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.

Purpose: To report a case of combined central retinal vein occlusion and branch retinal artery occlusion in a 51-year-old male with a very good response to dexamethasone implant therapy. Methods: This is a descriptive case report based on data from clinical records, patient observation and follow-ups, and analysis of acquired diagnostic tests. Results: A 51-year-old man presented with sudden vision loss and best-corrected visual acuity of 20/40 in his left eye. A pale inferotemporal arterial branch course area along with increased vascular tortuosity, retinal hemorrhages, optic disk swelling, and macular edema were observed on slit lamp biomicroscopy examination. Right eye was normal. Diagnosis of combined central retinal vein occlusion and branch retinal artery occlusion in left eye was confirmed by fluorescein angiography and color fundoscopy, respectively. Optical coherence tomography confirmed subretinal fluid and intraretinal cysts with a prominent middle-limiting membrane in the inner synaptic portion of the outer plexiform layer, corresponding to areas of paracentral acute middle maculopathy. Intravitreal dexamethasone implant was administered to the patient. One month later, visual acuity was recovered with complete absorption of macular edema. Functional and anatomical stabilization were confirmed after 24 months. Conclusion: Combined central retinal vein occlusion and branch retinal artery occlusion represents a rare condition, with variable functional outcomes due to the long-term complications such as macular edema. We hypothesize that prompt diagnosis and immediate intravitreal corticosteroid implant therapy reduced macular edema, thus contributing to arterial perfusion improvement, which in this case lead to a full sustainable recovery with limited functional and anatomical damage.

Plasma Total Homocysteine

Purpose Elevated plasma homocysteine is an independent risk factor for thrombosis and vascular disease. This prospective study compared plasma total homocysteine levels in patients with retinal vascular occlusive disease and in matched healthy controls. Methods We measured plasma total homocysteine in 56 consecutive patients with recently diagnosed retinal vascular occlusive disease: 36 had central retinal vein occlusion, 12 branch retinal vein occlusion, and 8 retinal artery occlusion, and compared them with 59 age- and sex-matched healthy controls. Homocysteine levels were determined by high-performance liquid chromatography with electrochemical detection. Hyperhomocysteinemia was defined as a plasma homocysteine level above the 95th percentile in the control group (13.6 μmol/L). Results Mean plasma total homocysteine levels were significantly higher in patients than controls (16.1 ± 8.3 vs. 8.96 ± 5.6 μmol/L p<0.001). Mean homocysteine levels were significantly higher in the retinal vein occlusion and retinal artery occlusion groups than the control group (15.3 ± 8.2 and 20.95 ± 6.9 vs 8.96 ± 5.6 μmol/L, p<0.001). Estimates of the relative risk indicated that the risk of hyperhomocysteinemia was significantly higher in patients with retinal vascular occlusive disease than controls. Hyperhomocysteinemia was present in 37 (66.1%) of the 56 patients with retinal vascular occlusive disease but only 2 (3.4%) controls (odds ratio [OR] 47.5, 95% confidence interval [CI] 9.8 - 149.9). Hyperhomocysteinemia was present in 29 (60.4%) of the patients with retinal vein occlusion (OR 43.5, 95% CI 8.77 - 141.93) and in 6 (75%) patients with retinal artery occlusion (OR 85.5, 95% CI 7.49 - 1173.1). Conclusions High plasma homocysteine is a risk factor for retinal vascular occlusive disease so it may be useful to measure homocysteine in the management of these patients. A randomized, controlled trial is required to study the effect of lowering with homocysteine folic acid and other B vitamins on the risk of recurrent vascular occlusion in the same eye or its development in the fellow eye.
