To evaluate the changes in contrast sensitivity following surgery for macula-on rhegmatogenous retinal detachment (RD).
This study included 65 eyes of 65 patients with unilateral macula-on RD undergoing primary scleral buckling or pars plana vitrectomy. We examined the logarithm of the minimum angle of resolution best-corrected visual acuity (logMAR BCVA) and contrast sensitivity with the CSV-1000E (Vector Vision Co., Greenville, OH) before and after surgery. From the data obtained with CSV-1000E, the area under the log contrast sensitivity function (AULCSF) was calculated. LogMAR BCVA and contrast sensitivity in the contralateral normal eyes was also measured to serve as the normal controls. Clinical data were collected, including age, gender, surgical procedures (scleral buckling or vitrectomy), number of retinal tears, circumferential dimension of retinal tears, and area of retinal detachment, to determine the clinical factors related to visual acuity and contrast sensitivity.
Preoperative logMAR BCVA and AULCSF were significantly worse in eyes with RD than in the contralateral normal eyes. AULCSF decreased significantly after surgery, but logMAR BCVA did not change by surgery. Postoperative AULCSF was significantly lower in RD eyes than in the control, but postoperative logMAR BCVA was not different between the two eyes. Multiple regression analysis revealed that postoperative AULCSF had significant correlation with circumferential dimension of retinal tears, while no clinical parameters were significantly associated with postoperative BCVA.
Surgery for macula-on RD did not change visual acuity, whereas contrast sensitivity was significantly influenced by surgery, with which the extent of retinal tears was associated.
