Purpose. To evaluate changes in anterior segment parameters measured by imaging in coronavirus disease 2019 (COVID-19) infection. Methods. This longitudinal observational study included patients who recovered from COVID-19. All subjects exhibited a confirmed diagnosis of COVID-19 with a positive result of nasopharyngeal reverse transcription-polymerase chain reaction evaluation. Corneal Pentacam (Oculus, Dutenhofen, Germany) imaging was performed at least two weeks after recovery from systemic COVID-19. Measurements were repeated one and three months later. Results. A total of 20 patients, 11 (55%) of whom were females, with a mean age of 35.5 ± 7.1 years (age range: 25–51 years) recovered from nonhospitalized COVID-19 infection, were enrolled in this study. An increase in the keratometry mean front, keratometry mean back, cornea volume, and anterior chamber depth was observed in the longitudinal evaluation; however, they showed no statistical significance. The anterior chamber volume was statistically increased at three-month follow-up, compared to baseline (baseline: 177.8 ± 36.68 mm3; three months: 182.25 ± 39.58 mm3, P=0.048). Conclusion. COVID-19 infection may affect the cornea and anterior segment.

Ophthalmology ,RE1-994 - Abstract
Purpose. To report a case of protein C deficiency with paracentral acute middle maculopathy (PAMM) and nonischemic central retinal vein obstruction (NI-CRVO). Case Report. A previously healthy twenty-one-year-old male was referred with sudden-onset, painless, unilateral paracentral scotomata in the right eye for a week. His uncorrected visual acuity was 20/20 in both eyes. In fundus examination of the right eye, mild venous tortuosity, retinal hemorrhages, and a gray-white opacity in the papillomacular bundle were observed. In the macular spectral-domain optical coherence tomography images, a hyperreflective band was noticed at the level of the inner nuclear layer, indicating PAMM. Fundus appearance and fluorescein angiography findings indicated NI-CRVO diagnosis made. The systemic and laboratory evaluations disclosed a protein C deficiency. Conclusion. In this report, in a healthy young male, combined PAMM and NI-CRVO showed to be the cause of blurred vision in the setting of protein C deficiency.

Ophthalmology ,RE1-994 - Abstract
Aim. This study was aimed at reporting a case of central retinal artery occlusion (CRAO) after rhinoplasty. Case Report. Unilateral blindness occurred in a 22-year-old woman after rhinoplasty with a history of transient visual loss due to migraine aura and vasospasm. The physical examination of the patient revealed a visual acuity of no light perception in the right eye, a 4+ relative afferent pupillary defect, disc swelling, cherry-red spot in the macula, and ischemic retina in the right eye. Based on the diagnosis of CRAO, the patient underwent anterior chamber paracentesis (AC tap) along with treatment with mannitol and intravenous hydrocortisone. Visual acuity improved to 1/10 after a two-month follow-up. Conclusion. Taking history is very important in rhinoplasty surgery, and vasoconstrictors should be limited in the patients with a suspected history of vasospasm.

Ophthalmology ,RE1-994 - Abstract
Purpose. To quantify the longitudinal changes of the optic nerve head (ONH) parameters and peripapillary retinal nerve fiber layer (pRNFL) thickness in patients recovered from coronavirus disease 2019 (COVID-19) using spectral-domain optical coherence tomography (OCT) analysis. Materials and Methods. In an observational longitudinal study, in patients recovered from COVID-19, ONH OCT images were recorded at least two weeks after recovery from the systemic disease as the baseline and after one and three-month follow-up. Ganglion cell complex (GCC) analysis, ONH parameters, and pRNFL thickness changes were measured. Results. A total of 36 eyes from 18 recovered COVID-19 patients including eleven (61.2%) females were studied. The average age was 35.5 ± 7.5 years. The pRNFL thickness in the nasal lower sector significantly decreased from 77 ± 18 μm in the first post-COVID-19 month to 74 ± 10 μm in the third month (P=0.8). The average, superior, and inferior pRNFL thickness remained unchanged. The average cup volume significantly decreased from 0.27 ± 0.15 mm3 at baseline to 0.19 ± 0.15 mm3 in the third post-COVID-19 visit (P=0.028). In terms of ONH morphologies including rim, disc and cup to disc area, and the vertical and horizontal ratio, the changes were not significant over the 3-month study period. Focal loss volume and global loss volume values were not changed significantly. Conclusion. Localized defect in the nasal lower sector of pRNFL is observed in 3-month post-recovery from COVID-19. Larger studies with longer follow-ups are required to reveal the exact changes in ONH parameters.

Objective. To evaluate the midterm longitudinal changes in chorioretinal structures in patients with coronavirus disease 2019 (COVID-19). Methods. Thirty-four eyes of 17 COVID-19 patients were enrolled. The patients underwent retinal and choroidal imaging upon the recovery (baseline) after 1 and 3 months. Retinal measurements in fovea, parafovea, and perifovea were recorded. To calculate choroidal vascularity index (CVI), luminal and total choroidal areas were measured using Sonada's method. Choroidal thickness was measured at the subfovea 500 microns temporal and nasal to the fovea. Results. Mean CVI was 0.64 ± 0.04 at baseline that significantly increased to 0.67 ± 0.05 (P = 0.012) after 1 month and again significantly decreased to 0.63 ± 0.05 after 3 months (P

Ophthalmology ,RE1-994 - Abstract
Purpose. To report an unusual case of gas expansion following oxygen therapy in a patient with sulfur hexafluoride (SF6) 20% tamponade after pars plana vitrectomy. Case Report. A 40-year-old man came to the clinic with severe ocular pain and redness and also vision decrease in his left eye three days after uncomplicated 23-gauge pars plana vitrectomy, internal limiting membrane peeling combined with phacoemulsification, and using 20% SF6 injection as a tamponade agent due to significant cataract and a full-thickness macular hole. In ophthalmic examinations of his left eye, high intraocular pressure (approximately 70 mmHg), a flat anterior chamber, and a gas-filled vitreous cavity were found. The patient had been hospitalized the day before due to carbon monoxide poisoning and had undergone oxygen therapy with a pure 100% mask for three hours. Conclusion. It seems that oxygen therapy or carbon monoxide poisoning increases the volume of gas in the patient’s vitreous cavity and the nonexpansile percentage of SF6 expands.

Ophthalmology ,RE1-994 - Abstract
Background. To report a patient with central retinal artery occlusion (CRAO) associated with sildenafil overdose. Case Presentation. A forty-two-year-old male presented three hours after sudden painless visual loss in the right eye. BCVA was counting finger in two meters, and relative afferent pupillary defect was positive. Fundus examination revealed retinal whiteness except in a limited area of papillomacular bundle and cherry red spot. He consumed two 100 mg film-coated sildenafil tablet (Vizarsin, Krka, d.d., Novo mesto, Slovenia) twelve hours apart, and the last one was six hours before visual loss. He was diagnosed with CRAO with cilioretinal artery sparing. Although we did not find any emboli, anterior chamber paracentesis was done. Four weeks later, BCVA improved to 20/80, with resolving of retinal edema. Cardiovascular, carotid arteries, and neurologic evaluations were negative for any predisposing factor. Conclusion. CRAO is a vision threatening condition that might be associated with the overdose of sildenafil.

Ophthalmology ,RE1-994 - Abstract
Purpose. To report the occurrence of acute, bilateral, central serous chorioretinopathy (CSC), and pachychoroid spectrum disorder findings in patients with coronavirus disease 2019 (COVID-19). Methods. In recovered cases of COVID-19 with visual disturbances, complete ocular examinations with multimodal retinal and choroidal evaluation, including enhanced depth imaging optical coherence tomography, fluorescein or indocyanine green angiography, and blue autofluorescence, were obtained. Results. Four COVID-19 recovered patients presented with bilateral blurred vision. Ocular examination and imaging revealed pachychoroid and pachyvessels associated with choroidal hyperpermeability without any obvious intraocular inflammation. Bilateral localized serous retinal detachment was obvious in three cases compatible with pachychoroid associated with CSC manifestation and pachychoroid pigment epitheliopathy in one patient. CSC was resolved with treatment by steroidal antimineralocorticoid (Eplerenone) in two patients and by photodynamic therapy in one patient. None of the patients reported emotional stress and history of corticosteroid consumption. Conclusion. Hyperpermeability of the choroid, pachychoroidopathy, or choroidal vessel congestion can be observed or exacerbated in association with COVID-19.

Ophthalmology ,RE1-994 - Abstract
Purpose. Herein, we report a case of primary intraocular lymphoma (PIOL) with the first presentation of bilateral Epstein-Barr virus- (EBV-) associated panuveitis. Case Presentation. A 69-year-old male was referred with a three-day history of blurred vision and pain and redness in his left eye following cataract surgery. Examination revealed panuveitis, vitritis, and necrotizing retinitis with retinal hemorrhage. A month later, the right eye was also involved. Polymerase chain reaction-based analysis of the vitreous sample was positive for EBV, and cytological evaluation was compatible with the diagnosis of B-cell lymphoma. A significant improvement was observed following serial intravitreal rituximab and methotrexate injections. The central nervous system and lungs were involved after 6 months, and the patient expired despite systemic chemotherapy. Conclusion. There may be an association between EBV panuveitis and primary intraocular B-cell lymphoma.

Background Chronic inflammation has a role in the pathogenesis of diabetic retinopathy. Infection with intracellular organisms may incite chronic inflammation. This study was conducted to investigate the association between previous infection with Chlamydia pneumoniae (an intracellular microorganism) and diabetic retinopathy. Methods Patients with type 2 diabetes mellitus (30–60 years old) and age-matched normal controls were recruited. Patients with history of cardiovascular or cerebrovascular disease, recent pulmonary infection and the presence of age-related macular degeneration were excluded from the study. Complete ophthalmic examinations were performed. Fasting blood sugar and haemoglobin levels were measured in diabetic patients and controls, and HgbA1c, blood urea nitrogen, creatinine and 24-h urine protein were measured in diabetic patients. Anti-C. pneumoniae IgG (enzyme-linked immunosorbent assay) was measured in the sera of all participants. Results A total of 215 type 2 diabetic patients and 243 normal healthy controls were included. Anti-C. pneumoniae IgG titers were higher in patients affected by diabetic retinopathy than participants without retinopathy (74.78 ± 33.38 vs 66.18 ± 31.40, p = 0.028). Diabetic patients with diabetic retinopathy also had higher titers than diabetic patients without diabetic retinopathy (74.78 ± 33.38 vs 66.11 ± 33.41, p = 0.042). Of different variables including age, body mass index, haemoglobin level, glycated haemoglobin level, fasting blood sugar, mean arterial pressure and blood urea nitrogen, only age (r = 0.17; p = 0.001) and body mass index (r = 0.15; p = 0.003) were correlated with anti-C. pneumoniae IgG levels. In regression analysis, the presence of diabetic retinopathy was still a determinant of the antibody level (p = 0.03). Conclusion Anti-C. pneumoniae IgG titers were higher in patients with diabetic retinopathy, which may indicate a role of this infection in the pathogenesis of diabetic retinopathy.

Background A major disadvantage of photorefractive keratectomy is postoperative pain and discomfort. This study aims to evaluate whether topical diclofenac 0.1% therapy adds any extra benefit to systemic diclofenac in controlling pain after photorefractive keratectomy. Design Prospective randomized, double-masked clinical trial applied in the Khatam-al-Anbia Eye Hospital, Mashhad University of Medical Sciences, Mashhad, Iran. Participants Sixty-eight individuals (age range, 18–35 years) having bilateral photorefractive keratectomy for myopic correction with or without astigmatism. Methods All patients received 100 mg of extended-release oral diclofenac two times (12-h interval) before photorefractive keratectomy surgery. Postoperatively, patients were randomized into the case and control groups. Case group was administered the diclofenac 0.1% drop, one drop 2 h preoperatively and four times daily postoperatively for 3 days, whereas the control group was given artificial tears instead. Main Outcome Measures Pain level, photophobia and functional activity were evaluated by the patient after operation. Results Two days after surgery, no statistically significant difference in pain level was noted between both groups. In addition, photophobia and functional activity was not different between the case and control groups. Eyelid oedema and conjunctival injection levels were significantly higher in the control group (P

Purpose To quantify distribution of conjunctival vessels in normal eyes and the changes induced by the irritation of photography. Methods Digital slit lamp photography of the upper and lower conjunctiva of 728 healthy eyes was done in 4 groups with different orders of succession of the photography in each person. A radon transform based algorithm was used to segment vessels and compute area occupied by vessels (AOV) of different sizes in each image. AOV of small, medium and large vessels were compared in the first photos of cases, and in the successive photos of each person using ANOVA (post hoc: Tukey) and paired sample T tests. Results AOV of the 3 sizes of vessels had normal distribution in all images. In the first images of photography (un-irritated eyes); AOV of medium sized vessels was the largest and was less in both fields of the left eye than the upper field of the right eye. Irritation of photography, caused an increase in AOV of the large vessels first, followed by increase in AOV of medium sized vessels accompanied by a decrease in AOV of small vessels, and finally a small increase in AOV of small vessels. Conclusion Medium sized vessels are the most abundant in un-irritated eye. During mild irritation, changes in large conjunctival vessels are documented first. Medium and small sized vessels seem to respond later.
