    Abstract:
    PURPOSE: To evaluate the efficacy and safety of hybrid 26-gauge needle drainage in scleral buckling for rhegmatogenous retinal detachment (RRD). METHODS: In this retrospective study, we included patients who underwent scleral buckling surgery along with subretinal fluid (SRF) drainage using the 'Hybrid 26G needle drainage technique'. Pre-operative assessment included the best corrected visual acuity (BCVA), lens status, and extent of retinal detachment. Intra-operative surgical details such as the height of retinal detachment, number of attempts required to drain the fluid, amount of fluid drained, adequacy of break buckle relationship, and any intra-operative or post-operative complications were noted. Post-operatively, the final visual outcome and retina status were assessed at 3 months of follow-up. RESULTS: A total of 10 eyes with primary RRD and proliferative vitreoretinopathy C1 or less were included. Pre-operatively, the mean BCVA was 2.43 ± 1.01 logMAR units, which improved significantly to 0.679 ± 0.45 logMAR units (p value < 0.05) at 3 months of follow-up. Regarding the extent of RRD, five eyes (50%) had a total detachment, two eyes (20%) had a sub-total detachment, and three eyes (30%) had an inferior detachment. Four eyes had shallow detachment, four had a moderate detachment, and two eyes had bullous detachment. Complete drainage of SRF (>75%) was achieved in five patients, and a partial but adequate drainage (50-75%) was achieved in the rest of the five patients. In none of the patients, inadequate or dry tap was encountered. No intra-operative complications were encountered. The retina was attached in eight out of ten eyes at 1 week and at a 1-month follow-up period. Two patients required pars plana vitrectomy for persistent SRF. The retina was attached in all the patients at 3 months of follow-up. CONCLUSION: The 'Hybrid needle drainage' technique is a safe and effective technique for SRF drainage in scleral buckling surgery.
