Abstract

Background

To evaluate stereopsis after successful surgery for unilateral rhegmatogenous retinal detachment (RD), and to investigate the relationship between stereopsis and clinical factors.

Methods

In 75 patients after RD surgery and 28 age-matched normal subjects, stereopsis was measured using the Titmus Stereo Test (TST) and TNO stereotest. Clinical data were collected, including age, gender, circumferential dimension of retinal tears, area and duration of RD, macular status, surgical procedures, postoperative spherical equivalent, and logarithm of the minimum angle of resolution best-corrected visual acuity (logMAR BCVA), low-contrast visual acuity, postoperative lens status (phakia/pseudophakia), and presence of postoperative epiretinal membrane (ERM), to determine the factors related to stereopsis.

Results

Stereopsis in patients after surgery was significantly worse than normal subjects (p < 0.0001). Stereopsis in TST was significantly correlated with the area of RD (p < 0.005), difference of postoperative spherical equivalent between two eyes (p < 0.05), postoperative logMAR BCVA (p < 0.005), difference of postoperative logMAR BCVA between two eyes (p < 0.01), and low-contrast visual acuity (p < 0.05). Stereopsis in TNO stereotest showed significant association with postoperative logMAR BCVA (p < 0.05). Stereopsis in both stereotests were significantly worse in patients with macula-off RD than macula-on RD (p < 0.005, p < 0.01 respectively). No significant relationship was found between stereopsis and other factors. Multiple regression analysis revealed that macular status (on/off) had a significant correlation with both stereopsis in TST and TNO stereotest (p = 0.028, p = 0.019 respectively), whereas other clinical parameters were not relevant.

Conclusions

Stereopsis is significantly deteriorated in patients after RD surgery than in normal subjects. Stereopsis was associated with the difference in refraction between two eyes, postoperative visual acuity and contrast sensitivity, and preoperative macular status.
