Abstract
Purpose: :
To evaluate stereoacuity after successful surgery for unilateral rhegmatogenous retinal detachment (RD), and to investigate the relationship between stereoacuity and other visual function as well as clinical factors.
Methods: :
In 75 patients after successful surgery for unilateral RD (age 53.9 ±10.7 years, means ± SD) and age-matched 20 normal controls, stereoacuity was measured using the Titmus Stereo Test (TST). Clinical data were collected, including age, gender, spherical equivalent, logarithm of the minimum angle of resolution best-corrected visual acuity (logMAR BCVA), contrast sensitivity, circumferential dimension of retinal tears, area of detachment, duration of disease, surgical procedures (scleral buckling or vitrectomy), and macular involvement, to determine the factors related with stereoacuity.
Results: :
Stereoacuity in patients after RD surgery was significantly worse than that in normal controls (p < 0.0001). LogMAR BCVA (p < 0.005), difference of logMAR BCVA between both eyes (p < 0.01), difference of spherical equivalent between both eyes (p < 0.05), 10% low contrast visual acuity (p < 0.05), and area of detachment (p < 0.005) were significantly correlated with stereoacuity. Stereoacuity was significantly worse in patients with macula-off RD than in patients with macula-on RD (p < 0.005). There was no significant relationship between stereoacuity and other factors.
Conclusions: :
Stereoacuity in patients after RD is significantly deteriorated than that in normal controls. Stereoacuity was associated with visual acuity, contrast sensitivity, macular involvement, and difference in refraction between both eyes.
