[Stereoacuity in Glaucoma Patients].

Purpose: Studies report that glaucoma significantly affects stereoacuity. We investigated the stereoacuity in glaucoma and preperimetric glaucoma patients.

Methods: The near stereoacuity in glaucoma patients and preperimetric glaucoma patients was evaluated using Titmus stereo test, and distance stereoacuity was evaluated using Distance Randot stereotest.

Results: We found a significant reduction both in near and in distance stereoacuity in the glaucoma group compared with the control group, but the difference between the preperimetric glaucoma group and the control group were not significant. We observed a trend of decrease in near stereoacuity with increase in age and increased number of central scotoma cases, as well as a trend of decrease in distance stereoacuity with increased age.

Conclusions: The near and distance stereoacuity in glaucoma patients was significantly impaired. Our results suggest that visual field damage within the central 5 degrees may affect the near stereoacuity in glaucoma patients.
