Abstract

PURPOSE
To describe the characteristics of the disabled patients visiting the eye clinic in our institute. METHODS: We carried out a retrospective analysis of 35 cases in our clinic from April 2004 to June 2008 using the McBride disability evaluation. We investigated the clinical features and the causes of disorders through visual acuity, visual field and ocular motility. RESULTS: Thirty-three (94.3%) of the 35 patients had disabilities due to trauma; twelve (34.3%) of them were caused by traffic accidents, and 21 (60%) of them were due to blows or lacerations. Other causes of disability were glaucoma and retinal break (5.8%). Nine patients (25.7%) had abnormal findings in the visual field examination, and nine other patients (25.7%) had limitations in ocular motility. Twenty-eight patients (80%) had decreased visual acuity, and nine (25.7%) had multiple symptoms. CONCLUSIONS: Considering the contribution of disability estimation of visual field and ocular motility in McBride disability evaluations, we considered the importance of repetitive examinations and evaluations. When patients complained of unexplained decreased visual acuity with no anatomical abnormalities, multifocal ERG and multifocal VEP should be considered in order to distinguish it from malingering or functional visual loss.
