Abusive head trauma (AHT) is an extreme form of physical child abuse, a subset of which is shaken baby syndrome (SBS). While traumatic injury in children is most readily observed as marks of contusion on the body, AHT/SBS may result in internal injuries that can put the life of the child in danger. One pivotal sign associated with AHT/SBS that cannot be spotted with the naked eye is retinal injury (RI), an early sign of which is retinal hemorrhage (RH) in cases with rupture of the retinal vasculature. If not addressed, RI can lead to irreversible outcomes, such as visual loss. It is widely assumed that the major cause of RI is acceleration-deceleration forces that are repeatedly imposed on the patient during abusive shaking. Still, due to the controversial nature of this type of injury, few investigations have ever sought to delve into its biomechanical and/or biochemical features using realistic models. As such, our knowledge regarding AHT-/SBS-induced RI is significantly lacking. In this mini-review, we aim to provide an up-to-date account of the traumatology of AHT-/SBS-induced RI, as well as its biomechanical and biochemical features, while focusing on some of the experimental models that have been developed in recent years for studying retinal hemorrhage in the context of AHT/SBS.

Purpose: To explore patterns of disease expression in Alagille syndrome (ALGS). Methods: Patients underwent ophthalmic examination, optical coherence tomography (OCT) imaging, fundus intravenous fluorescein angiography (IVFA), perimetry and full-field electroretinograms (ffERGs). An adult ALGS patient had multimodal imaging and specialized perimetry. Results: The proband (P1) had a heterozygous pathogenic variant in JAG1; (p.Gln410Ter) and was incidentally diagnosed at age 7 with a superficial retinal hemorrhage, vascular tortuosity, and midperipheral pigmentary changes. The hemorrhage recurred 15 months later. Her monozygotic twin sister (P2) had a retinal hemorrhage at the same location at age 11. Visual acuities for both patients were 20/30 in each eye. IVFA was normal. OCT showed thinning of the outer nuclear in the peripapillary retina. A ffERG showed normal cone-mediated responses in P1 (rod-mediated ERGs not documented), normal ffERGs in P2. Coagulation and liver function were normal. An unrelated 42-year-old woman with a de-novo pathogenic variant (p. Gly386Arg) in JAG1 showed a similar pigmentary retinopathy and hepatic vascular anomalies; rod and cone function was normal across large expanses of structurally normal retina that sharply transitioned to a blind atrophic peripheral retina. Conclusion: Nearly identical recurrent intraretinal hemorrhages in monozygotic twins with ALGS suggest a shared subclinical microvascular abnormality. We hypothesize that the presence of large areas of functionally and structurally intact retina surrounded by severe chorioretinal degeneration, is against a predominant involvement of JAG1 in the function of the neurosensory retina, and that instead, primary abnormalities of chorioretinal vascular development and/or homeostasis may drive the peculiar phenotypes.

Acute leukemia is a hematological malignancy affecting different organ systems including the eye and orbit through direct infiltration of tissues or secondary to hematological abnormalities. Ophthalmological manifestations in acute leukemia are variable ranging from asymptomatic presentation to serious manifestations that can alter the disease course and treatment. The purpose of this study is to detect the incidence of different ophthalmological manifestations in newly diagnosed acute leukemia patients and to assess the relationship between ocular findings and hematological characteristics and the sequel of these neoplasms. A cross-sectional study with analytical components was conducted on 222 newly diagnosed acute myeloid and acute lymphoblastic leukemia patients who presented at Oncology Center Mansoura University (OCMU) between January 2022 and February 2023. All patients underwent a complete ophthalmic evaluation at Mansoura Ophthalmology Center (MOC). The mean age was 43.45 ± 17.35 years (range, 17–85), and M/F was 137 (61.7%)/85 (38.3%). One-hundred and forty-four (64.9%) had acute myeloid leukemia (AML), and 78 (35.1%) had acute lymphoblastic leukemia (ALL). Ophthalmic manifestations were detected in 96 patients (43.2%). Among them, 4 (1.8%) had poor visual acuity. Retinal hemorrhage (19.8%) and Roth spots (17.1%) were the most common ocular manifestations. Other ophthalmological manifestations observed were orbital involvement (3.2%), ocular motility issues (1.4%), subconjunctival hemorrhage (5.9%), conjunctival chemosis (0.9%),lid swelling (4.1%), lid ecchymosis (3.2%), lagophthalmos (0.5%), lid ptosis (1.8%), retinal venous congestion & tortuosity (4.1%), preretinal hemorrhage (3.2%), vitreous hemorrhage (3.2%), macular affection (2.3%), retinal infiltration (1.8%), exudative retinal detachment (ERD) (1.8%), cotton-wool spots (0.9%), retinal vein occlusion (0.5%), papilledema (2.8%), optic disc infiltration (1.8%), disc pallor (1.8%).AML patients were significantly associated with a higher frequency of ocular affection, retinal hemorrhages, and Roth spots (P 0.028, 0.003, and 0.046, respectively) compared to ALL patients. Retinal hemorrhage was statistically significantly associated with anemia (P 0.021). Ophthalmological manifestations of acute leukemia are heterogeneous; they can be detected at initial presentations or relapse. Some manifestations are asymptomatic, others can affect visual acuity or even alter the disease course. Cooperation between ophthalmologists and haemato-oncologists is crucial for recognizing ocular involvement and disease management. [ABSTRACT FROM AUTHOR]

Purpose: To report a case of bilateral retinal hemorrhages in a patient undergoing two separate endovascular interventions for bilateral cerebral aneurysms. Methods: A comprehensive ophthalmic examination was performed after the patient underwent each of two separate endovascular interventions for bilateral cerebral aneurysms. Multimodal imaging including widefield pseudocolor fundus photography, optical coherence tomography, and widefield fluorescein angiography was obtained. A systemic workup including genetic testing and hypercoagulability studies was performed. Results: Dilated fundus examination revealed new visually significant ipsilateral retinal hemorrhages after each endovascular procedure. Fluorescein angiography showed evidence of a peripheral retinal microangiopathy present in both eyes before the patient underwent her second endovascular procedure. Systemic workup revealed persistently elevated serum anticardiolipin IgM antibody levels at .99th percentile. Conclusion: Retinal complications after endovascular intracranial interventions are uncommon. This patient who developed bilateral retinal complications was found to have persistently elevated anticardiolipin antibody levels, a risk factor for thrombosis. Patients who develop retinal complications after endovascular intracranial intervention may benefit from systemic workup for hypercoagulable conditions. [ABSTRACT FROM AUTHOR]

Retinal hemorrhages in pediatric patients can be a diagnostic challenge for ophthalmologists. These hemorrhages can occur due to various underlying etiologies, including abusive head trauma, accidental trauma, and medical conditions. Accurate identification of the etiology is crucial for appropriate management and legal considerations. In recent years, deep learning techniques have shown promise in assisting healthcare professionals in making more accurate and timely diagnosis of a variety of disorders. We explore the potential of deep learning approaches for differentiating etiologies of pediatric retinal hemorrhages. Our study, which spanned multiple centers, analyzed 898 images, resulting in a final dataset of 597 retinal hemorrhage fundus photos categorized into medical (49.9%) and trauma (50.1%) etiologies. Deep learning models, specifically those based on ResNet and transformer architectures, were applied; FastViT-SA12, a hybrid transformer model, achieved the highest accuracy (90.55%) and area under the receiver operating characteristic curve (AUC) of 90.55%, while ResNet18 secured the highest sensitivity value (96.77%) on an independent test dataset. The study highlighted areas for optimization in artificial intelligence (AI) models specifically for pediatric retinal hemorrhages. While AI proves valuable in diagnosing these hemorrhages, the expertise of medical professionals remains irreplaceable. Collaborative efforts between AI specialists and pediatric ophthalmologists are crucial to fully harness AIs potential in diagnosing etiologies of pediatric retinal hemorrhages.

Abusive head trauma is a serious type of child abuse that causes skull and brain damage as a result of the child being violently shaken and/or exposed to blunt trauma. It is seen in children under 5 years, most commonly under 2 years. Its classic triad is the simultaneous occurrence of subdural hematoma, retinal hemorrhage, and encephalopathy. Histopathological and immunohistochemical examinations at autopsy are crucial in determining the cause of death and the age of the lesions in cases resulting in death. While these examinations confirm the macroscopic diagnosis, they also enable the determination of macroscopically undetectable findings and the age of the trauma. Determining a protocol specifically for central nervous system examinations in cases of suspected child abuse and sampling by this standard approach will make significant contributions to the proper functioning of justice.

Abstract Aim This study analyzed whether retino‐dural hemorrhages in infants are markers of the degree of intracranial pathology, rather than evidence of violent shaking. Methods Using data from 420 infants with acute intracranial pathologies, comparison of clinical findings is made between cases diagnosed as abusive head trauma (AHT) and four categories: cases where caregivers report no trauma; cases of witnessed or admitted AHT; cases where caregivers report accidental trauma; and witnessed accidents. The data are then controlled for degree of intracranial pathology by only comparing cases in each category that have evidence of hypoxic‐ischemic swelling. Results Although categories differ in clinical findings when all data are considered, they do not differ when the data are controlled for degree of intracranial pathology. Conclusions The data suggest that the clinical findings widely considered to be indicative of shaking are instead markers of the degree of intracranial pathology. Previous results showing differences were driven by selection effects, whereby different categories have different fractions of serious cases. Most notably, caregiver and witnessed reports of accidental head trauma led doctors to explore intracranial pathologies across a broader spectrum of severity, including milder cases, as opposed to situations where no head trauma is reported.

Background: Acute promyelocytic leukemia (APL) is a distinct subtype of acute myeloid leukemia with a favorable prognosis. Hemorrhagic manifestations in APL at presentation are usually due to thrombocytopenia, consumptive coagulopathy, and fibrinolysis. Central nervous system (CNS) hemorrhage carries a risk for CNS relapse and early death in APL patients. Case Presentation: A 23-year-old male presented with sudden bilateral visual loss and headache. The ocular examination revealed a massive exudative retinal detachment in the right eye and bilateral dense vitreous hemorrhage. APL diagnosis was confirmed through peripheral blood and bone marrow examination, along with cytogenetic and molecular testing. The patient received 7+3 induction chemotherapy combined with All-trans-retinoic acid. After achieving complete remission, he underwent pars plana vitrectomy and silicone oil injection in the right eye. Intrathecal chemotherapy was considered for CNS prophylaxis after induction. Later, he had a medullary relapse which was managed with salvage therapy and autologous stem cell transplantation. Conclusion: Although APL has a favorable prognosis, its management can be complicated. It may present with retinal detachment or intraocular hemorrhage. Managing intraocular and intracranial hemorrhage is challenging due to the risks of hemorrhage and coagulopathy. This complexity is further heightened by poor visual prognosis, high risk of CNS infiltration, and potential for medullary relapse.

Leber’s hereditary optic neuropathy (LHON) causes subacute visual loss, and, in the acute phase, the optic disc shows hyperemia, peripapillary telangiectasia, and swelling of the retinal nerve fiber layer (RNFL). Rarely, retinal hemorrhage may be present. In this study, we investigated LHON cases with retinal hemorrhage in the acute phase. Among 82 cases (164 eyes) of LHON who visited the Inoue Eye Hospital, retinal hemorrhage was observed in 5 cases (5 eyes). The age at onset was 36 (27–46) years, with 4 male cases. Mitochondrial DNA analysis revealed the presence of the m.11778G > A variant in four patients and the m.14484T > C variant in one patient. There was no medical history and no excessive smoking or alcohol consumption in any of the cases. In all cases, retinal hemorrhages were observed in the RNFL, accompanying the characteristic optic disc findings of LHON. Fluorescein angiography performed in three cases showed no leakage from the optic disc or blood vessels. While rare, the presence of retinal hemorrhage along the RNFL during the acute phase of LHON should be recognized, as it may warrant consideration of alternative diagnoses. [ABSTRACT FROM AUTHOR]

Objective: Rare disease. Background: Terson's syndrome (TS) is a medical condition characterized by intraocular bleeding that can lead to visual impairment and is associated to subarachnoid hemorrhage (SAH). The pathophysiology and natural history are not well established in the current literature. This report describes successful treatment of a 52-year-old man with aneurysmal SAH who developed late-onset TS using balloon-assisted coiling and vitrectomy to raise awareness of this important complication of aneurysmal SAH. Case Report: A 52-year-old smoker with no known past medical history presented to the emergency department with a sudden, severe headache that worsened with photophobia and phonophobia. The patient had a diffuse SAH and underwent an embolization procedure. After 48 hours of close Intensive Care Unit monitoring, the patient's vital signs were stable, and the GCS score was consistently 15/15. However, after 3 weeks in the hospital, the patient experienced blurred vision and a right upper quadrantanopia. Further examination revealed TS and the patient underwent a vitrectomy in 1 eye. The surgery was successful and the eye recovered to 20/20 with no complications. However, the other eye showed slow absorption of the hemorrhage, and a vitrectomy was scheduled for that eye as well. Conclusions: TS is a complication of aneurysmal SAH that can lead to vision loss and increased morbidity. It often goes undiagnosed, and ophthalmologists are not regularly consulted. Late manifestation of the condition is exemplified by the present case. Early detection and intervention are crucial for better patient outcomes. [ABSTRACT FROM AUTHOR]

AIM: To explore the correlation between neonatal retinal hemorrhage(RH)and changes in umbilical artery blood gas analysis.METHODS: A total of 312 full-term neonates born in our obstetrics department from January 2019 to December 2021 were selected as the study subjects. According to the RetCam III fundus examination results, 245 neonates who did not experience RH were included in the control group, while 67 cases with RH were found to be included in the RH group. In addition, neonates were grouped into I degree group(n=20), II degree group(n=29), and III degree group(n=18)based on the degree of RH. General clinical data and umbilical artery blood gas analysis indicators between the RH group and the control group were compared; the levels of umbilical artery blood gas analysis indicators in neonates with different degrees of RH, the relationship between pH and RH degree, and the influencing factors of neonatal RH were analyzed.RESULTS: There was no obvious difference in maternal age, average gestational week, fetal gender, parity, gestational diabetes, fetal birth weight, and amniotic fluid between the RH group and the control group(all P>0.05), while there were obvious differences in delivery methods, gestational hypertension, forceps assisted delivery, neonatal asphyxia, and umbilical cord around the neck(all P

AIM: To explore the results of fundus screening in 5 307 newborns and the related factors of fundus diseases.METHODS: A total of 5 307 newborns who underwent fundus screening in our ophthalmology department from January to December 2022 were selected. RetCam III system was used for fundus examination, and abnormal fundus conditions were recorded. The influencing factors of retinal hemorrhage in full-term infants and retinopathy of prematurity(ROP)in preterm infants were analyzed.RESULTS: The incidence of ocular abnormalities in newborns was 27.17%, with the highest incidence of retinal hemorrhage(61.23%), followed by retinal exudation(22.95%), ROP and ROP like retinopathy(10.68%). The incidence of morning glory syndrome(0.21%), albino fundus(0.21%), and permanent fetal vasculature(PFV; 0.28%)was lower. The incidence of eye abnormalities in full-term infants was lower than that in preterm infants(26.30% vs 30.08%, P

Severe congenital protein C deficiency (SCPCD) is a rare disorder associated with life-threatening purpura fulminans and disseminated intravascular coagulation that typically present within hours after birth. Treatment options for patients with SCPCD include replacement therapy with a plasma-derived protein C concentrate. In this targeted literature review, we summarize information on the use of protein C concentrate as long-term prophylaxis (>1 week of treatment) for patients with SCPCD. In total, 18 publications were included in the review, of which 15 were case studies. Treatment with protein C concentrate (Ceprotin; Baxalta US Inc, a Takeda company; Takeda Manufacturing Austria AG) was reported in 11 publications, and treatment with protein C concentrate (Protexel; LFB Biomedicaments) was reported in 2 publications. One publication reported on both Ceprotin and Protexel. Details of protein C concentrate treatment regimens, including the dose, administration frequency, and route of administration, were reported in 11 publications. Dosing regimens varied across all 11 publications, possibly due to different protein C trough levels among patients or the administration of concomitant medications. Seven of the 11 publications reported on patients who initially received intravenous protein C concentrate and subsequently switched to subcutaneous administration. Treatment outcomes with protein C concentrate were generally favorable, including the prevention of coagulopathy and thrombosis and the healing of cutaneous lesions. Three adverse events in 1 publication were identified as being possibly related to Ceprotin administration. Although published data are limited, this review provides valuable insights into the treatment of patients with SCPCD in clinical practice, including protein C concentrate dosing regimens, administration routes, and associated clinical outcomes.

BackgroundAbusive head trauma (AHT) is a severe form of physical abuse leading to significant morbidity and mortality in children, often presenting with complex brain injuries. Among the varied manifestations, ophthalmologic presentations are critical yet underexplored, which may provide essential clues for early diagnosis and management, improving long-term visual and neurological outcomes.ObjectiveThis study aims to explore the manifestation, management, and outcomes of AHT cases within a single center in China over a five-year period, with a focus on the importance of ophthalmologic evaluation in enhancing the diagnosis, management, and outcome predictions of AHT.MethodsA retrospective case series was conducted at a single institution, involving infants diagnosed with AHT from 2019 to 2023. Data on demographics, medical histories, and clinical management were collected. Ophthalmologic examinations including fundus photography, ocular B-scan ultrasound and fundus fluorescein angiography (FFA), were performed to evaluate retinal vasculature and identify peripheral ischemic retina (PIR). Statistical analyses were performed using SPSS ver. 26.0.ResultsEight AHT patients (16 eyes) were included in the study. Bilateral ocular involvement was observed in all patients, with 81.25% exhibiting retinal hemorrhages (RH). Other manifestations included retinal detachment (31.25%) and optic nerve atrophy (18.75%). Clinical interventions varied, with 68.75% of patients undergoing treatments such as laser photocoagulation and anti-vascular endothelial growth factor (VEGF) injections. Among all eyes, 75% showed resolution of RH. Despite treatment, some patients progressed to severe conditions such as retinal detachment (RD) and iris neovascularization (INV).ConclusionThis study emphasizes the importance of a multidisciplinary approach in the diagnosis and management of AHT, particularly by integrating ophthalmological perspectives into patient care. These findings contribute to the understanding of ophthalmologic presentations in AHT.

PurposeTrauma to the eye resulting from a soccer ball is a common sports-related injury. Although the types of ocular pathologic features that result from impact have been documented, the underlying pathophysiologic mechanics are not as well studied. The purpose of this study was to evaluate the biomechanical events after the collision of a soccer ball with the eye to better understand the pathophysiology of observed ocular and retinal injuries and to compare them with those observed in abusive head trauma (AHT).DesignComputer simulation study.ParticipantsNone.MethodsA finite element model of the eye was used to investigate the effects of a collision of a soccer ball on the eye.Main outcome measuresIntraocular pressure and stress.ResultsImpact of the soccer ball with the eye generated a pressure wave that traveled through the vitreous, creating transient pockets of high and negative pressure. During the high-frequency phase, pressure in the vitreous near the posterior pole ranged from 39.6 to -30.9 kPa. Stress in ocular tissue was greatest near the point of contact, with a peak of 66.6 kPa. The retina experienced the greatest stress at the vasculature, especially at distal branches, where stress rose to 15.4 kPa. On average, retinal stress was greatest in the subretinal layer, but was highest in the preretinal layer when considering only vascular tissue.ConclusionsThe high intraocular pressure and stress in ocular tissue near the point of soccer ball impact suggest that injuries to the anterior segment of the eye can be attributed to direct transmission of force from the ball. The subsequent propagation of a pressure wave may cause injuries to the posterior segment as the positive and negative pressures exert compressive and tractional forces on the retina. The linear movement of the pressure wave likely accounts for localization of retinal lesions to the posterior pole or superior temporal quadrant. The primarily linear force in soccer ball trauma is the probable cause for the more localized injury profile and lower retinal hemorrhage incidence compared with AHT, in which repetitive angular force is also at play.

Purpose: Infantile acute subdural hematoma (IASDH) has a limited age distribution and mostly benign clinical features. Mild-type IASDH has a stereotypical clinical course which, however, has been described in only a few studies. Methods: Four male infants (aged 6–10 months; mean age: 7.5 months) were diagnosed as mild-type IASDH associated with retinal hemorrhage (RH) after suffering from occipital impact in a fall. The present case series reviews their clinical features and neuroimaging findings, including CT and MRI findings. Results: All the infants fell backwards from a standing or sitting position onto a soft surface, striking the occipital region. They began crying on impact and then soon afterwards exhibited seizure-like activity or recurrent vomiting. CT and MRI revealed a thin, unclotted subdural hematoma (SDH) without mass effect or brain parenchymal abnormality. Various degrees of bilateral RH were observed. On the day of symptom onset, all infants returned to baseline, and follow-up more than 5 years revealed normal development with no deficits. Conclusions: Mild-type IASDH with retinal hemorrhage presents with seizure-like activity or recurrent vomiting preceded by crying after an occipital impact on a soft surface. The clinical course of IASDH is followed by rapid recovery on the day of symptom onset. CT and MRI findings reveal a small, unclotted SDH without a mass effect or cerebral parenchymal abnormality.

PurposeTo investigate longitudinal changes in rates of optic nerve head circumpapillary retinal nerve fiber layer (cpRNFL) thinning and vessel density loss in patients with primary open-angle glaucoma with or without a history of disc hemorrhage (DH).DesignObservational cohort.MethodsIn this longitudinal study, 34 eyes with DH and 134 eyes without DH that had ≥1.5 years of follow-up and 3 optical coherence tomography and optical coherence tomography angiography follow-up scans were enrolled. A linear mixed-effects model was used to compare the rates of cpRNFL thinning and vessel density loss between DH and non-DH eyes.ResultsRates of whole image capillary density loss were faster in the DH group compared with the non-DH group (mean difference [95% confidence interval] -0.32% [-0.59% to -0.04%] per year; P = .027). Faster mean rates of vessel density loss were found in the inferotemporal, inferonasal, and nasal sectors in eyes with DH than without DH (P < .05). There was no statistically significant difference in the global rate of cpRNFL thinning between the 2 groups (P = .679). The mean rate of cpRNFL thinning was faster in the DH group compared with the non-DH group only in the inferotemporal sector (mean difference [95% confidence interval] -1.01 μm (-1.62 μm to -0.40 μm) per year; P = .001).ConclusionsMean rates of vessel density loss between DH and non-DH eyes were different not only in the affected area but also in the other regions. In contrast, a significant difference in cpRNFL thinning between the 2 groups was detected only in the inferotemporal sector. Disc hemorrhage is an independent predictor of faster vessel density loss in glaucoma suspects and patients with primary open-angle glaucoma.

Abstract Purpose To evaluate the clinical patterns of retinopathy in patients who received cardiopulmonary resuscitation (CPR) using wide-field fundus photography and slit-lamp fundus examination. Methods The medical records of patients aged ≥ 18 years who survived after receiving CPR and underwent wide-field fundus photography and slit-lamp fundus examination within 3 months were retrospectively analyzed. Fundus findings, including retinal hemorrhage and cotton wool spots, were investigated. The subjects were categorized into the retinopathy and non-retinopathy groups based on the presence of fundus findings. Systemic and CPR-related factors were analyzed to compare the two groups. Results Twenty eyes (10 patients) and 28 eyes (14 patients) were included in the retinopathy and non-retinopathy groups, respectively. The retinopathy group had longer CPR time than the non-retinopathy group (15 ± 11 min vs. 6 ± 5 min, p = 0.027). In the retinopathy group, retinal nerve fiber layer hemorrhage was observed in all eyes, and intraretinal hemorrhage was observed in 55% of the eyes. 80% of hemorrhages were located in the peripapillary or posterior pole. There were no interval changes in visual acuity, intraocular pressure, and central retinal thickness for 6 months. The average remission periods of retinal hemorrhage and cotton wool spots were 6.8 ± 2.6 month and 5.6 ± 2.1 months, respectively. No retinopathy progression was observed. Conclusion The signs of retinopathy, such as retinal hemorrhages and cotton wool spots, which are found after CPR, mainly occur in patients who receive longer time of CPR and improve over time.

PurposeTo investigate the characteristics and rate of central visual field loss after optic disc hemorrhage (DH).DesignProspective cohort study.MethodsThree hundred forty-three eyes of 220 subjects who had ≥3 years of follow-up with a minimum of 5 visits with 10-2 and 24-2 visual field (VF) were recruited. Rates of 10-2 mean deviation (MD) loss in each hemifield and predefined zones were compared using linear mixed-effects models in DH and non-DH eyes. Clustered pointwise regression analysis was also used to define central VF progressors and compared with 24-2 VF loss using guided progression analysis.ResultsThirty-nine eyes with DH and 304 eyes without DH had a mean follow-up of 5.2 years. Eyes with DH had rates of 10-2 MD loss that were 3 times faster than non-DH eyes (mean difference -0.36 dB/year [95% confidence interval 0.54-0.18]; P < .001) and were 3.7 times more likely to progress (P = .002). A larger proportion of glaucomatous eyes showed central VF progression rather than peripheral VF progression in the DH group (30.8% vs. 20.5%) compared with the non-DH group (10.9% vs. 9.2%). In early glaucoma, the rate of 10-2 MD loss was 5.5 times faster in DH eyes than in non-DH eyes (P < .001). Superonasal and superotemporal central VF regions progressed more rapidly than other regions, especially in DH eyes.ConclusionCentral VF loss is accelerated in glaucoma eyes with DH and it corresponds topographically to the DH location. In patients with glaucoma with DH, one should consider supplementing 10-2 VFs with 24-2 VFS to monitor the disease.

Factor VII (FVII) is an important, vitamin K-dependent clotting factor. Acquired FVII deficiency is a rare entity that is associated with serious bleeding complications. We report a case of acquired FVII deficiency in a patient with recurrent chronic myeloid leukemia in blast crisis who developed bilateral retinal hemorrhages. The coagulopathy was corrected with the initiation of chemotherapy and subsequent reduction in peripheral blast count. [ABSTRACT FROM AUTHOR]

Abusive head trauma is the leading cause of physical child abuse deaths in children under 5 years of age in the United States. To evaluate suspected child abuse, radiologic studies are typically the first to identify hallmark findings of abusive head trauma including intracranial hemorrhage, cerebral edema, and ischemic injury. Prompt evaluation and diagnosis are necessary as findings may change rapidly. Current imaging recommendations include brain magnetic resonance imaging with the addition of a susceptibility weighted imaging (SWI) sequence which can detect additional findings that suggest abusive head trauma including cortical venous injury and retinal hemorrhages. However, SWI is limited due to blooming artifacts and artifacts from the adjacent skull vault or retroorbital fat, which can affect the evaluation of retinal, subdural, and subarachnoid hemorrhages. This work explores the utility of the high-resolution, heavily T2 weighted balanced steady-state field precession (bSSFP) sequence to identify and characterize retinal hemorrhage and cerebral cortical venous injury in children with abusive head trauma. The bSSFP sequence provides distinct anatomical images to improve the identification of retinal hemorrhage and cortical venous injury. [ABSTRACT FROM AUTHOR]

Ocular decompression retinopathy (ODR) is characterized by multiple retinal hemorrhages. It is a rare complication associated with rapid decrease of intraocular pressure (IOP). The course of ODR is usually asymptomatic and self-limiting, which was confirmed by the observation of our patient. In this study, we present a 5-month follow up of a 77-year-old woman with acute right eye (RE) filtration angle closure who developed symptoms of ODR. Clinical examination and multimodal imaging modalities, including color fundus photography, optical coherence tomography (OCT), OCT angiography (OCTA) and fluorescein angiography (FA), were used to confirm the diagnosis and performed regularly in monitoring the course of the disease. Fundus lesions in the RE included diffuse intraretinal hemorrhages in the posterior pole, which gradually resolved during follow-up time. The fundus of the left eye (LE) was normal. The patient underwent conservative therapy, laser therapy and surgery, achieving stabilization of the IOP and improvement of the local condition in the RE. Of the various multimodal imaging techniques, color fundus photography and OCT seemed to be the most specific and helpful in monitoring the patient with ODR. [ABSTRACT FROM AUTHOR]

PRECIS: In this prospective cohort study, disc hemorrhages were associated with more severe central damage on 24-2 and 10-2 visual fields (VFs), and faster progression globally on 24-2 VFs and centrally on 10-2 VFs. PURPOSE: To study the relationship between disc hemorrhage (DH) and the presence and progression of glaucomatous central VF damage. METHODS: Cross-sectional and longitudinal analyses were performed on data from the African Descent and Glaucoma Evaluation Study (ADAGES) cohort. Two masked investigators reviewed disc photographs for the presence and location of DH. 24-2 central VF damage was based on the number of test locations within the central 10 degrees of the 24-2 field pattern deviation and their mean total deviation (MTD). 10-2 central VF damage was based on pattern deviation and MTD. Main outcome measures were the association between DH and presence of central VF damage and between DH and worsening of VF. RESULTS: DH was detected in 21 of 335 eyes (6.2%). In the cross-sectional analysis, DH was significantly associated with more severe central damage on 24-2 [incidence rate ratio=1.47; 95% confidence interval (CI)=1.02-2.12; P=0.035] and 10-2 VFs (incidence rate ratio=1.81; 95% CI=1.26-2.60; P=0.001). In the longitudinal analysis, DH eyes progressed faster than non-DH eyes based on 24-2 global MTD rates (difference in slopes, β=-0.06; 95% CI=-0.11 to -0.01; P=0.009) and 10-2 MTD rates (β=-0.10; 95% CI=-0.14 to -0.06; P< 0.001), but not 24-2 central MTD rates (β=-0.02; 95% CI=-0.078 to 0.026; P=0.338). CONCLUSION: DH was associated with the presence and progression of central VF defects. DH identification should prompt intensive central VF monitoring and surveillance with 10-2 fields to detect progression.

The main objective of this study was to evaluate the retinas of severely or critically ill COVID-19 patients during their hospital stay, at varying time points after symptoms onset. This was a case series observed during May 2020 in two referral centers for COVID-19 treatment in Rio de Janeiro, Brazil. 47 eyes from 25 hospitalized patients with severe or critical confirmed illness were evaluated. A handheld retinal camera was used to acquire bilateral fundus images at several time points after symptoms onset. Electronic health records were retrospectively analyzed and clinical data collected. Severe and critical diseases were noticed in 52% (13/25) and 48% (12/25) of enrolled patients, respectively. Retinal changes were present in 12% (3/25) of patients: a 35 year-old male demonstrated bilateral nerve fiber layer infarcts and microhemorrhages in the papillomacular bundle, but required mechanical ventilation and developed severe anemia and systemic hypotension, acute kidney injury and neurologic symptoms during the course of the disease (critical illness); a 56 year-old male, who required full enoxaparin anticoagulation due to particularly elevated D-dimer (>5.0 mcg/mL), demonstrated unilateral and isolated flame-shaped hemorrhages; and a 49 year-old hypertensive male showed bilateral and discrete retinal dot and blot microhemorrhages. The other 22 patients evaluated did not demonstrate convincing retinal changes upon examination. There was no correlation between disease severity and admission serum levels of CRP, D-dimer and ferritin. This was the first study to show that vascular retinal changes may be present in not insignificant numbers of severe or critical COVID-19 inpatients. These retinal changes, only seen after morbid developments, were likely secondary to clinical intercurrences or comorbidities instead of a direct damage by SARS-CoV-2, and may be important and easily accessible outcome measures of therapeutic interventions and sentinels of neurologic and systemic diseases during COVID-19 pandemic.

PurposeTo compare the rates of retinal nerve fiber layer (RNFL) thinning after intraocular pressure (IOP) lowering procedures in eyes with or without disc hemorrhage (DH) history.DesignObservational cohort study.MethodsA total of 166 primary open angle glaucoma (POAG) eyes and glaucoma suspect eyes (37 eyes with DH history (DH group) and 129 eyes without DH (non-DH group)) were included from the African Decent and Glaucoma Evaluation Study (ADAGES) and the Diagnostic Innovations in Glaucoma Study (DIGS). Subjects underwent stereoscopic optic disc photography annually and spectral-domain optical coherence tomography (OCT) RNFL thickness measurements every 6 months. The rates of RNFL thinning were compared in eyes with and without DH using univariate and multivariable linear mixed effects models.Main outcome measuresThe rates of RNFL thinning.ResultsThe mean follow-up of DH group and non-DH group was 4.6 years and 4.2 years, respectively. DH group had more procedures (2.4 vs. 1.9, P= 0.080) before follow-up, and more medications (1.8 vs. 1.4, P= 0.052) and lower mean IOP (12.69 mmHg vs. 14.41 mmHg, P= 0.012) during follow-up compared to non-DH group. When mean IOP was adjusted as a covariate in the model, the RNFL thinning rate in the DH group was 2-fold faster than in the non-DH group (-0.61 μm /year vs. -0.33 μm /year, P= 0.025). Higher mean IOP during follow-up was associated with a faster rate of RNFL thinning after procedures.ConclusionsPOAG or glaucoma suspect eyes with a history of DH should be carefully followed after IOP-lowering procedures. Additional IOP-lowering may be needed to slow structural progression of the DH eyes to the same rate as the non-DH eyes.

Abstract Background Ophthalmic manifestations are common in patients with leukemia, developing in nearly 50% of cases. Intracranial hemorrhage is another potentially fatal complication of leukemia. In this case report, we aim to present a challenging case that involves both ophthalmic and intracranial manifestations in an individual with acute monocytic leukemia. Case presentation A 36-year-old Persian male presented to the emergency room with complaints of fever, headache, and bilateral blurred vision. The patient had been diagnosed with acute monocytic leukemia 3 months prior and had undergone four sessions of induction chemotherapy, the last of which was 10 days prior to admission. The patient was admitted to the internal medicine service, and initial lab studies confirmed pancytopenia, including severe neutropenia, anemia, and thrombocytopenia. Subarachnoid hemorrhage in the left frontal lobe was detected through spiral brain computed tomography scan. Ophthalmic examination revealed visual acuity of light perception in the right eye and 3-m finger count in the left eye. Fundus examination revealed bilateral peripapillary subhyaloid and intraretinal hemorrhages, confirming leukemic retinopathy. The patient showed significant improvement in visual acuity and hemorrhage resolution through conservative treatment and regular follow-ups after 3 months. Conclusion Simultaneous subarachnoid hemorrhage and bilateral subhyaloid hemorrhages seemed to have occurred as a result of pancytopenia. Management approach of ophthalmic manifestations of leukemia involves interdisciplinary cooperation and should be individualized on the basis of the patients’ underlying medical condition.

Abstract Background Since the development of the coronavirus disease 2019 vaccine, there have been many reports of its adverse effects. While respiratory symptoms are common, many other symptoms in various organs have been reported. Herein, we report a case of optic disc and retinal hemorrhage that developed immediately after coronavirus disease 2019 vaccination. Case presentation A healthy 18-year-old Japanese female noticed floater in the left eye 1 day after the second vaccination for coronavirus disease 2019 (Pfizer Inc.). Her visual acuity was 20/20 in the left eye, and Goldmann visual field test showed a relative scotoma around blind spot and in the temporal lower quadrant. It was considered due to subretinal hemorrhage and optic disc swelling. Fundus examination revealed retinal and optic disc hemorrhage. Pupillary reflex was intact and central critical flicker was not impaired, indicating that optic nerve was not involved. There was no sign of inflammation, vascular abnormality, nor history of an intense Valsalva maneuver. The hemorrhage resolved spontaneously within 5 months. Conclusion This case expands the clinical presentation of coronavirus disease 2019 vaccination-associated ocular adverse events, and it should be kept in mind when patients with similar symptoms visit clinics. The case report will help clinicians avoid unnecessary and invasive examinations and treatment.

AIM: To investigate the ratio of spontaneous regression of retinopathy of prematurity (ROP) and to explore the possible relevant predictive factors. METHODS: A retrospective review of 405 infants who were diagnosed with ROP and mother during pregnancy were collected. Stage, zone, and duration of ROP were recorded. Statistical analysis was performed on 51 possible predictive factors. RESULTS: Totally 356 infants showed spontaneous regression. The incidence was 100%, 95.3%, and 22.7% in stage 1, 2, and 3, respectively. The 13.4% of the ROP with plus disease eventually resolved spontaneously. All affected eyes of aggressive posterior retinopathy of prematurity (AP-ROP) failed to spontaneously regress. The mean duration of ROP was 7.2wk in patients with spontaneous resolution of ROP. Days of mechanical ventilation (OR=0.981, 95%CI, 0.965-0.997, P=0.021), retinal hemorrhage (OR=0.173, 95%CI, 0.064-0.470, P=0.001), delivery pattern (OR=2.750, 95%CI, 1.132-6.681, P=0.025), maternal anemia in pregnancy (OR=0.142, 95%CI, 0.036-0.563, P=0.005), the stages (at initial diagnosis OR=0.183, 95%CI, 0.041-0.816, P=0.026; at final diagnosis OR=0.031, 95%CI, 0.006-0.167, P

(1) Background: Head trauma represents the first cause of death in abused children, but diagnostic knowledge is still limited. The characteristic findings of abusive head trauma (AHT) are retinal hemorrhages (RH) and additional ocular findings, including optic nerve hemorrhages (ONH). However, etiological diagnosis must be cautious. (2) Methods: The Preferred Reporting Items for Systematic Review (PRISMA) standards were employed, and the research focus was the current gold standard in the diagnosis and timing of abusive RH. (3) Results: Sixteen articles were included for qualitative synthesis. The importance of an early instrumental ophthalmological assessment emerged in subjects with a high suspicion of AHT, with attention to the localization, laterality, and morphology of the findings. Sometimes it is possible to observe the fundus even in deceased subjects, but the current techniques of choice consist of Magnetic Resonance Imaging and Computed Tomography, also useful for the timing of the lesion, the autopsy, and the histological investigation, especially if performed with the use of immunohistochemical reactants against erythrocytes, leukocytes, and ischemic nerve cells. (4) Conclusions: The present review has made it possible to build an operational framework for the diagnosis and timing of cases of abusive retinal damage, but further research in the field is needed.

Naturally occurring cell death is a fundamental developmental mechanism for regulating cell numbers and sculpting developing organs. This is particularly true in the nervous system, where large numbers of neurons and oligodendrocytes are eliminated via apoptosis during normal development. Given the profound impact of death upon these two major cell populations, it is surprising that developmental death of another major cell type-the astrocyte-has rarely been studied. It is presently unclear whether astrocytes are subject to significant developmental death, and if so, how it occurs. Here, we address these questions using mouse retinal astrocytes as our model system. We show that the total number of retinal astrocytes declines by over 3-fold during a death period spanning postnatal days 5-14. Surprisingly, these astrocytes do not die by apoptosis, the canonical mechanism underlying the vast majority of developmental cell death. Instead, we find that microglia engulf astrocytes during the death period to promote their developmental removal. Genetic ablation of microglia inhibits astrocyte death, leading to a larger astrocyte population size at the end of the death period. However, astrocyte death is not completely blocked in the absence of microglia, apparently due to the ability of astrocytes to engulf each other. Nevertheless, mice lacking microglia showed significant anatomical changes to the retinal astrocyte network, with functional consequences for the astrocyte-associated vasculature leading to retinal hemorrhage. These results establish a novel modality for naturally occurring cell death and demonstrate its importance for the formation and integrity of the retinal gliovascular network.

OBJECTIVE: The aim of this study is to determine the incidence and characteristics of newborns with subconjunctival hemorrhage (SCH). METHODS: In our study, patient files of term infants referred to the study hospital's ophthalmology clinic in 2018-19 were analyzed. Demographic data of infants including gestational week, birth weight, gender, and head circumference were all recorded. The frequency of SCH detection was evaluated depending on delivery type. Demographic data of infants with and without retinal hemorrhage (RH) were compared. RESULTS: A total of 172 eyes of 86 infants were included in study. Forty-two (48.8%) of 86 neonates were male, and 44 (51.2%) were female. Mean gestational week was 38.62±1.1. SCH was detected in 31.4% (27) in the right eye, 36% (31) in the left eye, and 32.6% (28) in both eyes. The diagnosis was made at the mean of 3.74 days (range 1-20). Mean birth weight was found as 3621.1±453.3 g, head circumference as 35.4±1.3 cm, height as 50.7±2 cm, and chest circumference as 33.6±1.4 cm. Mean Apgar score in 1st min was 7.1±0.4; 5th min was 9. About 11.6% (10) of the mothers were nulliparous, and 88.4% (76) were multiparous. It was found that 79 of the deliveries were vaginal and seven with cesarean section. RH was not detected in any of the infants born with cesarean section. CONCLUSION: SCH and RH were more common in infants born vaginally. If SCH is detected, a fundus examination should be performed to not miss possible RH. [ABSTRACT FROM AUTHOR]

Child physical abuse may result in a range of injuries to the globe and surrounding tissues. These injuries have varying degrees of specificity for abuse, and no pattern of injury is unique to abuse. Easily overlooked eye injuries in non-ambulatory infants often portend more severe abuse and require careful evaluation for occult injury when they are unexplained. Retinal hemorrhages are most often a sign of significant trauma and the severity of the hemorrhages generally parallels the severity of neurological trauma. Ophthalmologists contribute important data that more easily distinguish medical disease from trauma, but caution is needed in differentiating accidental from inflicted trauma. This distinction requires careful consideration of the complete clinical data and occasionally on additional law enforcement or child welfare investigation. [ABSTRACT FROM AUTHOR]

AIM: To summarize and analyze the results of neonatal eye screening using digital wide-area fundus imaging system(RetCam3)in general hospital, and to provide references for the prevention and treatment of neonatal eye diseases.METHODS: There were 7 239 newborns subjected to eye examinations in Zhongshan City People's Hospital from December 2018 to December 2021, and RetCam3 was used to obtain eye screening images. Newborns with abnormal screening results were treated and followed up accordingly.RESULTS: Among 7 239 newborns, 1 200(16.58%)newborns were diagnosed with abnormal eyes, including 7 cases of anterior segment abnormalities and 1 193 cases of fundus abnormalities. Among 7 cases of anterior segment abnormalities, 2 cases were congenital cataract, 2 cases were pupillary residual membrane, and 3 cases were corneal leukoplakia. Among 1 193 cases of fundus abnormalities, 1 141 cases were retinal hemorrhage(RH), and 19 cases were retinopathy of prematurity(ROP). In addition, there were 6 cases of ROP-like in term infants.CONCLUSION: Neonatal ocular abnormalities mainly develop in the posterior segment of the eye. Neonatal eye disease screening in general hospitals is beneficial to early detection and treatment of neonatal ocular diseases.

Retinal hemorrhages in pediatric patients can be a diagnostic challenge for ophthalmologists. These hemorrhages can occur due to various underlying etiologies, including abusive head trauma, accidental trauma, and medical conditions. Accurate identification of the etiology is crucial for appropriate management and legal considerations. In recent years, deep learning techniques have shown promise in assisting healthcare professionals in making more accurate and timely diagnosis of a variety of disorders. We explore the potential of deep learning approaches for differentiating etiologies of pediatric retinal hemorrhages. Our study, which spanned multiple centers, analyzed 898 images, resulting in a final dataset of 597 retinal hemorrhage fundus photos categorized into medical (49.9%) and trauma (50.1%) etiologies. Deep learning models, specifically those based on ResNet and transformer architectures, were applied; FastViT-SA12, a hybrid transformer model, achieved the highest accuracy (90.55%) and area under the receiver operating characteristic curve (AUC) of 90.55%, while ResNet18 secured the highest sensitivity value (96.77%) on an independent test dataset. The study highlighted areas for optimization in artificial intelligence (AI) models specifically for pediatric retinal hemorrhages. While AI proves valuable in diagnosing these hemorrhages, the expertise of medical professionals remains irreplaceable. Collaborative efforts between AI specialists and pediatric ophthalmologists are crucial to fully harness AI’s potential in diagnosing etiologies of pediatric retinal hemorrhages.

Context: Neonatal retinal hemorrhage (RH) is a condition occurring in newborns within 1 month of birth. Long-standing, dense hemorrhages obscuring the macula may lead to severe vision deprivation amblyopia. Aims: This study aimed to estimate the incidence of retinal hemorrhages (RHs) in full-term newborn babies in a medical college tertiary care hospital over a period of 1 year and to determine the association between RH and the mode of delivery. Settings and Design: This was a prospective observational study. Subjects and Methods: Screening was done in 469 full-term newborn babies within a week of delivery. Pupils were dilated with 0.4% tropicamide and 2.5% phenylephrine. Retinal evaluation was done with indirect ophthalmoscope and 20D lens. Statistical Analysis Used: Data analysis was done using SPSS software version 21. Chi-square test was used to assess the association between sex of the baby, mode of delivery, birth weight, and RH. P < 0.05 was considered statistically significant. Results: Out of 469 babies screened, 27 had RH on fundus examination. Of the 266 babies who were born spontaneously through vaginal route, 20 babies had RH. Eleven babies were delivered through vacuum-assisted vaginal delivery, of which 5 had RH. Babies weighing >2.5 kg had a higher incidence of RH (6.3%). There was no significant association between sex and RH. Conclusion: The incidence of RH in newborn babies was found to be 5.8%. Incidence of RH was found to be high among vacuum-assisted delivery followed by spontaneous vaginal delivery. Babies weighing >2.5 kg had a higher incidence of RH. By 2 weeks after birth, RH resolved in 96.29% of eyes.
