Abstract
Purpose :
To compare anatomical and functional outcomes of 25-gauge pars plana vitrectomy (PPV) and sulfur hexafluoride (SF6) gas for rhegmatogenous retinal detachment (RRD) associated with multiple breaks in multiple quadrants versus those with breaks limited to a single quadrant.
Methods :
A retrospective cohort study of patients with RRD who underwent 25-gauge PPV. Group A consisted of patients with identified breaks involving two or more quadrants. Group B consisted of patients with breaks involving a single quadrant.
Results :
Overall, 118 eyes of 118 patients with a mean age of 60.4 ± 11.8 years and 57.6% being males. Twenty seven with breaks involving multiple quadrants (Group A) and 91 with breaks limited to a single quadrant (Group B). The mean follow up time was 5 months (range 2-24 months). Single surgery anatomical success was achieved in 92.6% (25/27) of Group A and 93.4% (85/91) of Group B patients (P=0.88) with final anatomical success achieved in all cases. In regression analysis, the number of quadrants with breaks did not significantly account for the variation in single surgery success or visual outcomes. No significant differences were found between Groups A and B in terms of ETDRS letters of improvement (47.2 ± 58.1 and 41.3 ± 52.5 respectively, p=0.64) and final BCVA (0.56 ± 0.61 logMAR and 0.46 ± 0.45 logMAR respectively, p=0.40).
Conclusions :
Favorable results were achieved using 25-gauge vitrectomy and SF6 gas for the primary RRD treatment with multiple breaks in multiple quadrants. No differences in anatomical and functional success rates were observed between RRD associated with breaks involving multiple quadrants or those limited to a single quadrant.
