Abstract Details


To describe the clinical characteristics at diagnosis of the patients with retinal vein occlusion (RVO).


Ophthalmology Department, Hospital de Egas Moniz, Centro Hospitalar Lisboa Ocidental, Lisbon, Portugal.


Retrospective case review of the patients diagnosed with RVO in our Ophthalmology Department from 2009 to 2013. Baseline clinical characteristics were analyzed: age, sex, risk factors, central/branch RVO, extent and localization, Snellen corrected distance visual acuity (CDVA), fluorescein angiography (FA) and optical coherence tomography (OCT) findings.


97 patients were included, 52 with central RVO (34 females and 18 males) and 45 with branch RVO (25 females and 20 males). Mean age of the female and male patients with CRVO was 72,13 ± 7,13 and 62,94 ± 9,70 years respectively. Mean age of the patients with BRVO was 68,44 ± 6,98 for females and 64,71 ± 7,77 for males. Of the 45 patients with BRVO, 32 had temporal superior localization (71,1%). Of the 52 patients with CRVO 8 had inferior hemiretinal vein occlusion and 2 patients superior hemiretinal vein occlusion. Systemic hypertension was the main risk factor in our population, followed by hyperlipidaemia in the BRVO patients and by raised intraocular pressure in CRVO patients. Mean CDVA of female patients with BRVO was 0,27 and with CRVO was 0,11 (excluding 2 patients with light perception (LP)). Mean CDVA of male patients with BRVO was 0,41 and with CRVO was 0,08. Thirty-five patients with CRVO had FA available at baseline: 57% were classified as nonischemic, 26% as ischemic and 17% as undetermined. Sixty-six patients had OCT at baseline. Macular cystoid edema was present in 82% of the patients with CRVO and 63% of the patients with BRVO


Our results are similar to those reported in the literature except that CRVO was more prevalent in our population and females were more affected than males.
