ABSTRACT
Purpose The purpose of this study is to retrospectively analyze single-operation success (SOS) rates of pneumatic retinopexy (PR) for the treatment of rhegmatogenous retinal detachment (RRD) and to identify the predictors of treatment outcomes. Methods Sixty-one eyes of 61 patients who underwent PR for RRD during a period of 12 years were included in this study. Patient demographics along with pre-treatment clinical characteristics were recorded. Treatment outcomes in terms of best-corrected visual acuity (BCVA) and anatomical characteristics were reported including any post-operative complications. Visual outcomes were compared according to pre-treatment characteristics and between groups of the eyes achieving SOS and those requiring additional surgery. Results SOS was achieved in 37 (61%) eyes. Twenty-four (39%) eyes required one (36%) or two (3%) additional procedures. There was no significant association between pre-treatment characteristics and treatment failure. SOS eyes had significantly better visual outcomes (P=0.002), and so did those with macula-on status (P=0.003). New/missed breaks (9.8%) and proliferative vitreoretinopathy (PVR) (4.9%) were the most common causes of failure. Conclusions We found PR to be a beneficial technique for the treatment of RRD in this cohort. PR remains the least invasive treatment modality, and as a cost-effective technique, it is especially useful in low/middle-income countries such as Pakistan.
