Baseline Characteristics and Risk Factors for Retinal Vein Occlusions

Introduction: Venous obstructive disease of the retina iscausing significant visual morbidity affecting quality of lifeof patient. Incidence of CRVO is 0.8 per 1000 persons and 4.4per 1000 persons for BRVO. RVO most commonly affects thevenous blood supply of entire retina [CRVO] or a quadrantdrained by one of the branches [BRVO] less commonlysuperior or inferior half of retina alone is affected [HRVO].Study Aimed to study demographic characteristics and riskfactors of Retinal Vein Occlusions (Both CRVO and BRVO)Material and methods: This is a cross sectional observationstudy. It included 208 patients [64 CRVO patients and 144BRVO patients]at Retina department, Sarojini Devi EyeHospital, Hyderabad. Study was conducted for 1 year and 7months.Results: Hypertension stands alone as the most significantrisk factor (P Value is 0.005). Other factors studied likeUrban Background, Lack of physical Activity, Diabetes,Hyperlipidemias, CVA, CAD etc. though were present in goodnumbers in the cases studied but they were not statisticallysignificant.Conclusion: Hypertension, Diabetes and Raised SerumLipids are significant risk factors for Retinal Vein Occlusionsin South Indian population

Unusual retinal manifestations of PORN combined complications of central retinal artery and vein occlusions / 国际眼科杂志(Guoji Yanke Zazhi)

·AIM:To describe an unusual combination of retinal manifestations in an AIDS patient with progressive outer retinal necrosis (PORN),complicated by combined central retinal artery occlusion (CRAO) and central retinal vein occlusion (CRVO).·METHODS:A case report.·RESULTS:The patient presented with PORN with primary optic nerve involvement complicated by combined central retinal artery occlusion(CRAO) and central retinal vein occlusion(CRVO) as a primary manifestation of Varicella Zoster Virus (VZV).Aggressive treatment with intravitreal and specific systemic anti-VZV therapy,in addition to systemic highly active antiretroviral therapy (HAART) achieved retinal quiescence with sparing of the fellow eye.Visual outcome of the affected eye was poor.·CONCLUSION:We present the first report of PORN associated with the unusual combined complications of CRAO and CRVO. Aggressive local treatment was combined with systemic therapy,which achieved local control and empirical prophylaxis for the fellow eye.

Characteristics of Acute Hemorrhagic Central Retinal Vein Occlusion

PURPOSE: To investigate the characteristics of patients with acute hemorrhagic central retinal vein occlusion. METHODS: We reviewed the medical records of 124 eyes of 122 patients who were diagnosed to have central retinal vein occlusion within one month after onset and followed for six months or longer. Eyes were divided into three groups - ischemic, hemorrhagic and nonischemic - and the visual prognosis and complications were compared among the three groups. RESULTS: The hemorrhagic group had a tendency to be a male and younger than the other groups. The mean initial and final visual acuity of the hemorrhagic group was logMAR 1.23 and 1.54, respectively, and showed significant decrease rate of visual acuity compared to that of ischemic group (p=0.022), logMAR 1.31 and 1.35, respectively. Iris neovascularization (INV) / angle neovascularization (ANV) occurred in 6 eyes (7.4%) of the ischemic group and in 3 eyes (12.5%) of the hemorrhagic group. The mean period form the initial examination to INV/ANV occurrence was 4.67 and 2.33 months, respectively. All eyes of the hemorrhagic group and 4 eyes (66.7%) of the ischemic group with INV/ANV progressed to neovascular glaucoma. CONCLUSIONS: The hemorrhagic group had a worse final visual acuity, a greater decreasing rate of visual acuity, and earlier occurrence of INV/ANV than ischemic group. Close follow-up and proper management are warranted in patients with acute hemorrhagic central retinal vein occlusion.

A Case of Central Retinal Vein Occulsion Successfully Treated with Unsei-in and Gorei-san / 日本東洋医学雑誌

The prognosis of central retinal vein occlusion (CRVO) is generally poor. I report a case of a 67-year-old man with CRVO who underwent Kampo therapy. He ultimately continued to use Unsei-in for one year and 10 months, and he also continued to use Gorei-san for 9 months with no severe side effects. His visual acuity, which was LV: 0.02 (n. c.) before this therapy, has improved to LV: 0.2(0.3×S+0.75D_??_C-1.0DA×110°). Ocular neovascularization did not occur. These results suggest Kampo therapy is effective on CRVO.

Central Retinal Vein Occlusion During Embolization for Carotid Cavernous Sinus Fistula

Most trauma induced fistulas are direct communications between the intracavernous carotid artery and the cavernous sinus. Theses abnormal communications are characterized by high pressure, high blood flow and a clinically obvious constellation of symptoms and signs. We here in report a patient with traumatic carotid cavernous sinus fistula(CCSF). who developed central retinal vein occlusion(CRVO) during detachable balloon embolization. The mechanism of CRVO occurring during detachable balloon embolization. The mechanism of CRVO occurring during detachable ballon embolization for CCSF was discussed. We report this case with the review of previous reports.
