PURPOSE: To evaluate the success rate of pneumatic retinopexy (PR) for treatment of primary rhegmatogenous retinal detachment (RRD) and to explore preoperative factors associated with the success rate of PR.
METHODS: We conducted a retrospective study, having reviewed medical records of all patients diagnosed with primary RRD that underwent a single PR in Thammasat university hospital, Thailand, during 2016 to 2018. Preoperative ocular characteristics, postoperative anatomical and visual outcomes were collected.
RESULTS: 68 eyes of 68 patients were enrolled. Success rate of a single PR was 42.6%. The significant predictors were location of lowest retinal breaks (P < 0.001) and extension of retinal detachment (P < 0.002). In multivariate logistic regression analysis for the group with successful outcome, the patients whose lowest retinal breaks were located within thhe superior 2 clock hours were found to be 13.55 times more likely to respond successfully to PR (OR=13.55, 95%Cl 3.82-48.01, P<0.001). The success rate of PR was 0.722 times when the extension of retinal detachment increased for 1 clock hour (OR=0.722, 95%Cl 0.535-0.974, P=0.033). Out of the 29 patients from the success group, 27 (93%) patients had improvement of BCVA. Postoperative complications included new or missed break (12%), subconjunctival gas (10%), raised IOP (4%), vitreous haemorrhage (3%) and subretinal gas (1%).
CONCLUSIONS: The success rate of a single PR in primary RRD was 42.6%. The location of lowest retinal breaks and extension of retinal detachment were significant preoperative predictors of success in single PR for RRD. Final BCVA was improved in most patients with successful PR.
