Abstract
BACKGOUND: Intravitreal injections are the most common treatment modality for several retinal pathologies. Despite endophthalmitis being the most feared complication, antibioprophylaxis remains controversial in intravitreal injections. METHODS: This was a retrospective study done for a period of 2 years from 1st January 2017 to 31st December 2018 in B. P Koirala Lions Centre for Ophthalmic Studies (BPKLCOS) among patients receiving intravitreal bevacizumab. The intravitreal injection was given by a single surgeon. It included 503 eyes which received intravitreal bevacizumab over a period of 2 years without pre and postoperative antibiotics. RESULTS: Out of 503 eyes studied over a period of 2 years without antibiotic prophylaxis the rate of endophthalmitis was 0.0019% which is very low compared to the other studies with rate of endophthalmitis between 0.019-0.09%. CONCLUSION: The risk of endophthalmitis was low even without pre/post-operative antibiotics. Intravitreal injection can be given safely without pre-operative and post-operative antibiotics. Trial Registration not applicable as it is a retrospective study.
