Abstract

Aim: To find out outcome following single intravitreal injection of ranibizumab in central retinal vein occlusion (CRVO) patients in a government hospital in the capital of Odisha.

Methods: This study was a prospective interventional study of 18 months duration done from August 2017 to February 2019 included 15 cases of CRVO. Thorough history was taken and detail ophthalmological evaluation was done. Best corrected visual acuity (BCVA) was examined with Snellen’s chart and central macular thickness (CMT) was measured using optical coherence tomography (OCT). Routine blood tests were done. Intravitreal injection of ranibizumab 0.5 mg in 0.05 ml was given. BCVA and CMT was measured at 1 day, 1 week, 1 month and 3 month follow up visit.

Results: Mean age was 59.53 ± 8.65 years.  Male: female ratio was 2.8:1. Diastolic blood pressure of ≥ 90 was found in 46.7% patients.  60% cases showed improvement at 1 week post-operatively.At post-operative day 1 CMT was significantly decreased (p= 0.0193). Reduction in mean CMT at post-operative day 7 was >290 µ.

Conclusion: Single intravitreal injection of ranibizumab 0.5 mg in 0.05 ml causes significant increase in vision and significant reduction of central macular thickness in patients with branch retinal vein occlusion.
