Abstract
Purpose :
Retinal Vein Occlusion (RVO) has been observed following cataract surgery, most notably with respect to vancomycin-associated haemorrhagic occlusive retinal vasculitis. Only one other case series reports a non-vancomycin associated RVO following surgery.
Methods :
In this retrospective, single centre study, we analyzed data from all patients with a new diagnosis of RVO at first follow-up after cataract surgery between Oct 2015-2016. We continued to observe these patients and assessed BCVA at 1 year following presentation.
Results :
In our study, 5 patients (mean age= 79.8± 9.52; 40% female) were identified. Of these, 4 (80%) developed cystoid macular oedema requiring intravitreal anti-VEGF therapy. All surgeries were reported as uneventful. Mean Pre-operative BCVA was 0.38±0.11 log MAR, postoperative after cataract surgery was 0.41±0.36 and the final VA outcome after treatment of macular oedema was 0.27±0.06. Co-morbidities included: 4 patients with hypertension, 2 with renal disease and 1 with diabetes type 2 and hypercholesterolemia.
Conclusions :
During this study, we noted that hypertension, vascular risk factors and IOP fluctuation during surgery were identified as risks for the development of RVO. Visual outcomes appear to more favourable in comparison to haemorrhagic occlusive retinal vasculitis. RVO may affect cataract surgery outcome and high-risk patients should be adequately counselled.
