BackgroundTo evaluate the safety and efficacy of intravitreal conbercept (IVC) injection in the treatment of retinopathy of prematurity (ROP).MethodsPatients with ROP who underwent IVC injection in Zhujiang Hospital from June 2015 to July 2016 were studied retrospectively. The primary outcome was defined as the regression of plus disease. The secondary outcomes were defined as the presence of recurrence, number of injections and the final regression of disease.ResultsA total of 48 eyes of 24 patients with ROP were included. Among them, 9 eyes of 5 patients had zone I ROP, 35 eyes of 18 patients had zone II ROP and 4 eyes of 2 patients had aggressive posterior ROP. The mean gestational age was 28.5±1.6 weeks, the mean birth weight was 1209.6±228.6 g, the mean postmenstrual age of first injection was 34.2±1.9 weeks and the mean follow-up period was 31.0±4.7 weeks. Forty of 48 eyes (83.3%) received IVC only once, and the regression of plus disease occurred at an average of 3.5±1.5 weeks after the first injection of conbercept. For eight recurrent eyes (16.7%), four eyes received a second IVC and the remaining four eyes received laser photocoagulation, and the regression of plus disease occurred in 3 weeks. No lens opacity, vitreous haemorrhage, entophthalmia or retinal detachment was observed during follow-up.ConclusionIVC injection is an effective treatment for ROP.

Background: Diabetic retinopathy (DR) is the leading cause of blindness in most industrialized countries. This study was undertaken to assess the variability of IOP following laser photocoagulation used in the treatment of diabetic retinopathy.Methods: This study was conducted at Department of Opthalmology, B.R.D. Medical College, Gorakhpur from June 2015 to December 2016. This study was intended to see the onset and duration of intraocular pressure spikes in diabetic retinopathy patients after green laser photocoagulation (532 nm) (Nidek). Forty patients were followed for next 3 months. The data was analysed by using SPSS version 15.0. Chi-square test and T test was used.Results: Out of 40 patients, 2 (5%) had background Diabetic retinopathy (DR) with maculopathy, 10 (25%) having pre-proliferative DR, 28 (70%) having proliferative DR. Out of 2 BDR patients, 1 (50%) developed immediate post laser angle closure (Schaffer's grade 1) which persisted for 3 days and another had shown no change in angle structure. Out of 10 PPDR patients, no one developed post laser angle closure (0%). Out of 28 PDR patients, 6 (21.4%) had post laser angle closure which included 4 patients who had angle closure before laser, that means around 7% patients developed angle closure in this group. Among these 2 patients, 1 developed angle closure immediately (Schaffer's grade 1) and another developed the same 1 day later and this angle closure (Schaffer's grade 1) remained for 3 days.Conclusions: Laser photocoagulation in diabetic retinopathy patients can cause increase in IOP.
