Retinal sensitivity linked to functional impairment after retinal reattachment
Delayed recovery of the outer retinal thickness may be associated with reduced macular sensitivity after reattachment of a macula-off rhegmatogenous retinal detachment, according to a study.
The study included 23 eyes of 23 patients who underwent surgery for acute macula-off rhegmatogenous retinal detachment; 10 eyes underwent scleral buckling and 13 eyes underwent pars plana vitrectomy.
Best corrected visual acuity, central foveal thickness, retinal thickness and retinal sensitivity were evaluated at 3 and 6 months postoperatively.
Study results showed that logMAR BCVA improved from 0.89 to 0.14 at 6 months; the gain was significant (P < .001).
Central foveal thickness had no apparent effect on BCVA at 3 or 6 months. Increased outer retinal thickness of the macula at 3 and 6 months after scleral buckling was associated with reduced retinal sensitivity in the central 10° of the retina.
