영문 초록

Purpose: To evaluate the stereoscopic acuity in patients with unilateral or bilateral visual field defects. Methods: Stereoscopic acuity was measured using the Titmus stereo test for 36 subjects with visual field defects (VFD). VFD was assessed by sum of MD (mean deviation, MDsum) and PSD (pattern standard deviation, PSDsum) of both eyes in Humphrey visual field test and presence of central VFD (within 30° isopter) in Goldman visual field test. 25 glaucoma subjects and 11 optic neuritis subjects were included. Patients with strabismus or ocular motility disorders which could affect stereoscopic acuity were excluded. Results: The mean of MDsum was -20.10 ± 12.31 dB (-45.13~-10.64 dB) and PSDsum was 13.10 ± 8.76 dB (9.62-25.47 dB). The mean stereoscopic acuity was 710 ± 922 arc sec (40-3000 arc sec) with Titmus stereo test. The associations between stereoscopic acuity and PSDsum (r = 0.400, p = 0.016), presence of central VFD within 30 degrees (r = 0.428, p = 0.03) were statistically significant. There was positive trend between stereoscopic acuity and duration of VFD, but with no statistical significance. Conclusions: Decreased stereoscopic acuity was associated with PSDsum and VFD in the central 30 degrees. We should consider this decrease of stereoscopic acuity as well when evaluating visual function of the patients with VFD. J Korean Ophthalmol Soc 2014;55(5):734-739
