Abstract

OBJECTIVE: Predominantly hemorrhage represents one of the possible manifestations of choroidal neovascularisation (CNV) in eyes with age-related macular degeneration (AMD). The purpose of this study is to evaluate the effecte of ranibizumab treatment in patients with predominantly hemorrhagic CNV secondary to AMD. METHODS: Twenty-five patients with predominantly hemorrhagic choroidal neovascularization due to AMD with at least three ranibizumab injections and followed up for at least 12 months were included in the study. The months of follow-up were recorded (baseline, 3rd, 6th, and 12th months). The change in central macular thickness (CMT) on optical coherence tomography, visual acuity (VA) in ETDRS letters, and lesion size on fundus fluorescein angiography were evaluated. RESULTS: The mean age of the patients was 68.1±5.7 (range: 63-82) years, the mean follow-up was 19.9±14.5 (range: 12-67) months, and the mean number of injections was 4.0±1.4 (range: 3-15). The initial VA was 39.3±17.9 (range: 1-65) letters, CMT was 272.7±104 (range: 164-587) µm, and the initial lesion width was 11.4±10.5 (range: 1.3-45.7) mm2. The VA was 41.4±20.1 (range: 5-75) and 36.9±21.8 (range: 4-80) letters (p=0.150), CMT was 270.7±110 (range: 159-570) and 230.4±108 (range: 109-667) µm (p=0.009) and the lesion width was 10.9±11.5 (range: 1.1-39.7) and 10.4±11.6 (range: 1.2-44.3) mm2 at 6th and 12th month, respectively. No factor was found to be associated with final CMT. CONCLUSION: Although the final visual outcome is limited by the progression of the disease, hemorrhagic lesions treated with ranibizumab have stable anatomical outcome. [ABSTRACT FROM AUTHOR]

Abstract

Background To evaluate the prevalence, risk factors and treatment of retinopathy of prematurity (ROP) in Turkey and to establish screening criteria for this condition., Methods A prospective cohort study (TR-ROP) was performed between 1 April 2016 and 30 April 2017 in 69 neonatal intensive care units (NICUs). Infants with a birth weight (BW)=1500 g or gestational age (GA) 1500 g or GA> 32 weeks with an unstable clinical course were included in the study. Predictors for the development of ROP were determined by logistic regression analyses., Results The TR-ROP study included 6115 infants: 4964 (81%) with a GA 32 weeks. Overall, 27% had any stage of ROP and 6.7% had severe ROP. A lower BW, smaller GA, total days on oxygen, late-onset sepsis, frequency of red blood cell transfusions and relative weight gain were identified as independent risk factors for severe ROP in infants with a BW=1500 g. Of all infants, 414 needed treatment and 395 (95.4%) of the treated infants had a BW, Conclusions Screening of infants with a GA

Abstract

Objective: To determine the vitreous and serum concentrations of TNF-alpha, IL-6, VEGF, IL-1 beta, IL-8, IL-17, MCP-1, IL-1Ra, IL-10 in patients with proliferative diabetic retinopathy (PDR) and to investigate the effect of adipose tissue on the pathogenesis of PDR. Methods: Twenty-two patients with PDR were prospectively evaluated. Seven cadavers and 11 patients with idiopathic epiretinal membrane or macular hole served as the controls. Multiplex bead array technology was employed to assess the concentrations of the cytokines. Results: The intravitreal levels of VEGF, IL-8, IL-6 were significantly higher in PDR group than control groups. In PDR group, the levels of IL-17, IL-8, IL-6 were significantly elevated in the vitreous, whereas the intravitreal levels of IL-10, IL-1Ra were found to be significantly lower than the serum concentrations. No significant correlation was found between cytokine levels and body mass index (BMI), fasting blood glucose (FBG), or glycated haemoglobin (HbA1c) of diabetic patients. Conclusion: In PDR the balance between the intravitreal pro-and anti-inflammatory adipo-cytokines is disturbed in favor of proinflammatory and proangiogenic cytokines in the vitreous humour. This study supports the role of adipocytokines in vascular pathology in PDR. It seems that PDR is a local inflammatory disease. However, obesity may not be the root of the inflammatory mediators in PDR.

Abstract

BACKGROUND/OBJECTIVES: To analyze the ophthalmic characteristics of congenital prepapillary vascular loop (PVL) and to propose a new morphologic classification dividing the loops into six types. SUBJECTS/METHODS: Collaborative multinational multicentre retrospective study of PVL cases. RESULTS: There was a total of 49 cases (61 eyes), 37 unilateral (75.5%) and 12 bilateral (24.5%), 32 arterial type (65.3%) and 18 venous type (36.7%) (one patient had either kind in each eye). The mean number of loops per eye was 2.7 (range, 1-7). The loops were asymptomatic in 42 cases (85.7%). Other findings included: the presence of cilioretinal artery (14 cases), retinal vascular tortuosity (26 cases), amaurosis fugax (1 case), branch retinal artery occlusion (1 case) and vitreous haemorrhage (3 cases). Six morphologic loop types could be discerned based on elevation (flat vs. elevated), shape (figure of 8 or corkscrew with hyaline sheath), number (multiple or single), location (central or peripheral), lumen size (arterial vs. arteriolar) and presence of vascular tortuosity or vitreous traction. CONCLUSIONS: PVL are usually asymptomatic and can be divided into six morphologic types with different pathogenesis during early embryogenesis.

17. A rare galactosemia complication: vitreous hemorrhage.

Author

Abstract

Galactosemia is a secondary glycosylation disorder characterized by galactose deficiency of glycoproteins and glycolipids. Abnormal glycosylation of coagulation factors and evidence of liver disease are associated with coagulopathy in galactosemic infants. We report a case of a neonate with galactosemia presenting with bilateral vitreous hemorrhage (VH). During the follow-up, hemorrhage in the right eye resolved; however, it persisted in the left eye. Vitrectomy was planned for the left eye. In addition to cataract, VH is another ophthalmic finding in galactosemia with serious sequelae such as amblyopia. Serious complications of coagulopathy in galactosemic infants can be prevented with early diagnosis and prompt treatment. Inclusion of galactosemia in the neonatal screening program offers an opportunity to prevent early severe symptoms.
