During the COVID-19 pandemic, precautionary measures taken by various countries include individual movement restrictions causing significant lifestyle changes and affecting dietary patterns. A 23-year-old woman presented with reduced left eye vision over 1 week and amenorrhea for 4 months. She was diagnosed with severe iron-deficiency anaemia causing central retinal vein occlusion and amenorrhea. During the lockdown, there was a change in her diet with greatly reduced iron intake. Iron is an essential mineral for retina metabolism and function. Iron supplementation was done with improvement in her vision. This case demonstrates the potential impact of lockdown measures on nutrition and health. Education of the general population on maintaining appropriate nutrition during periods of movement restriction is important and that nutritional evaluation and supplementation should be considered in patients with drastic changes in dietary pattern.

Purpose: To report our findings in 2 patients who developed a central retinal vein occlusion (CRVO) and were chronic users of antipsychotic medications. Case Presentation: Case 1 was a 62-year-old woman who had a sudden reduction of vision in her right eye to 20/2,000. Her fundus showed signs of an impending CRVO with marked macular edema. She had been taking antipsychotic drugs (quetiapine fumarate and risperidone) for about 2 years. She refused anti-VEGF therapy for her macular edema but selected systemic kallidinogenase. Two days later, the macular edema was significantly reduced but the number of cotton wool spots (CWS) was increased. Ten days later, the macular edema was resolved and her BCVA improved to 20/60. The CWS gradually disappeared, and her BCVA improved to 20/20. Case 2 was a 43-year-old man who presented with vision reduction in his right eye of 1 week’s duration. His BCVA was 20/50 and his fundus showed signs of a CRVO-related macular edema with CWS in the peripapillary area. He had been taking sulpiride (DogmatylTM) for depression for 1 year, and his blood test showed an increase in red blood cells and hematocrit. Anti-VEGF therapy was performed, and the macular edema was resolved with vision improving to 20/20. There has been no recurrence to date in both cases. Conclusions: These results indicate that a CRVO can be a complication of chronic use of antipsychotic medications. However, early treatment can lead to good outcomes. Clinicians should question patients who develop a sudden CRVO whether they are using antipsychotic medications.

SummaryA series of coagulation parameters and lipoprotein(a) (Lp(a)) were explored in plasma from 40 patients with central retinal vein occlusion (CRVO, non-ischemic type n = 12; ischemic type n = 28) free of local and systemic predisposing factors, 1 to 12 months after the acute event. Forty age- and sex-matched patients with cataract served as controls. Prothrombin fragment 1.2 (FI.2), D-dimer, FVII:C - but not FVII: Ag - were higher and fibrinogen was lower in CRVO patients than in controls. Patients with non-ischemic CRVO had higher FI .2 and FVII:C and lower heparin cofactor II than patients with ischemic CRVO. Lp(a) levels greater than 300 mg/1 were observed in 12 patients with CRVO and in 4 controls (30% vs 10%, p <0.025). Patients with high Lp(a) - consistently associated with the S2 phenotype - had higher FVII:C, FVII:C/Ag ratio, and fibrinogen than the remaining CRVO patients. Plasma FI.2 and D-dimer correlated fairly in controls (r = 0.41) and patients with normal Lp(a) levels (r = 0.55), but they did not in the group of patients with high Lp(a) (r = 0.19), where the latter parameter was negatively related to D-dimer (r = −0.55). There was no dependence of the abnormalities observed on the time elapsed from vein occlusion. The findings of activated FVII and high FI.2, D-dimer, and Lp(a) are not uncommon in patients with CRVO. Increased thrombin formation with fibrin deposition and impaired fibrinolysis may play a role in the pathophysiology of CRVO and require specific treatment

Aims and Objective - The aim of the present study is to identify risk factors associated with different retinal vascular occlusive diseases (RVOD), such as central retinal artery occlusion (CRAO), hemi-retinal artery occlusion (HRAO), branch retinal artery occlusion (BRAO), cilioretinal artery occlusion (Cilio-RAO), central retinal vein occlusion (CRVO), branch retinal vein occlusion (BRVO), and hemi-retinal vein occlusion (HRVO). Patients and Method - A cross-sectional study on 114 consecutive subjects, aged 24-96 years who have attended at the outpatient department of ophthalmology at Shyam Shah Medical College, Rewa, MP, were included in the study. The Duration of study was January 2016 to December 2017. Only patients with CRAO, BRAO, HRAO, Cilio-RAO, CRVO, BRVO, and HRVO were included in the study. Other retinal vascular disorders such as diabetic vaso-occlusive disease, anterior and posterior ischemic and non-ischemic neuropathy, hypertensive retinopathy, sickle cell retinopathy, retinal telangiectasia, retinopathy of prematurity, were excluded from study. Results - We have included 114 patients, 64 cases (56.14%) males, 50 (43.85%) females, aged 56+/-8 years (range 24-96 years).  Bilateral retinal vascular occlusive disorders were seen in only 4 cases (3.5%). Two patients have bilateral CRVO followed by one case of bilateral BRVO and one case of bilateral CRAO.  Out of 114 patients, branch retinal vein occlusion was seen in 62 cases (54.38%), followed by central retinal vein occlusion in 36 cases (31.57%), CRAO in 8 cases (7.01%), and hemi- retinal vein occlusion in 4 cases (3.50%). Hypertension was the most common, (40 cases, 35.08%) risk factor identified for retinal vascular occlusive disorders followed by diabetes 24 cases (21.05%), combined diabetes and hypertension in 22 cases (19.29%), and atherosclerosis in 18 cases (15.78%). Conclusions - Retinal vascular occlusive diseases have systemic as well as ocular risk factors. Understanding of these risk factors is essential for proper treatment of RVOD. Timely identification of risk factors for RVOD may helpful in decreasing ocular and systemic morbidity in these patients.
