To determine the relationship between preoperative variables and visual recovery after treatment by pars plana vitrectomy (PPV) for macular-off rhegmatogenous retinal detachment (RRD) with posterior vitreous membrane.
This prospective study reviewed 63 patients with macula-off RRDs. Age, gender, preoperative and postoperative visual acuity (VA), duration of macular detachment, axial length, residual subfoveal fluid and position of causative tear were recorded for all patients. The patients underwent successful vitreous surgery without buckling procedure. We examined the correlation between preoperative variables and postoperative VA.
There are significant correlations for preoperative visual acuity (p< 0.001), age (p< 0.011) and the position of causative tear (p< 0.031) against postoperative VA. No significant correlations between the postoperative VA and other variables (duration macular detachment, gender, axial length and residual subfoveal fluid.
The correlation between the preoperative and postoperative VA was most significant, suggesting that patients with poor preoperative visual acuity already have an irreversible damage in the detached retina. Accordingly, it is considered that the preoperative visual acuity reflects a condition of the retina.
