Anatomical and Functional Results Following 23-Gauge Primary Pars Plana
Vitrectomy for Rhegmatogenous Retinal Detachment: Superior versus
Inferior Breaks
Purpose. In this retrospective study, we evaluated the anatomical and
functional outcomes of patients with rhegmatogenous retinal detachment
primarily treated with pars plana vitrectomy in regard to the location
of the breaks. Methods. 160 eyes were enrolled in this study, divided
into two groups based on break location: the superior break group (115
eyes) and the inferior break group (45 eyes). The main endpoint of our
study was the anatomical success at 3 months following surgery. Results.
Primary retinal reattachment was achieved in 96.5% of patients in group
A and in 93.3% in group B (no statistically significant difference, OR
1.98, 95% CI: 0.4, 7.7). Mean BCVA change and intraoperative
complication rate were also not statistically significantly different
between the two groups (p > 0 05, OR: 1.0, 95% CI: 0.9, 1.01, resp.).
Statistical analyses showed that macula status, age, and preoperative
BCVA had a significant effect on mean BCVA change (p = 0 0001, p = 0
005, and p = 0 001, resp.). Conclusion. This study supports that
acceptable reattachment rates can be achieved using PPV for
uncomplicated RRD irrespective of the breaks location and inferior
breaks do not constitute an independent risk factor for worse anatomical
or functional outcome
