Abstract

PURPOSE
To evaluate the clinical effect of Head Mounted Visual Enhancement System. METHODS: We assesd the clinical effect after prescription in 21 patients that visited the low vision clinic from October 2001 to April 2002. RESULTS: The average age is 33.6 years old. The causes of low vison were optic atrophy (29%), retinitis pigmentosa (19%), congenital cataract (14%), macular degeneration (14%). The most common best corrected distant visual acuity before prescription is from 20/200 to 20/100 (42%). After prescription, the most common best corrected distant visual acuity is better than 20/25 (71%). The most common best corrected near visual acuity before prescription is from 20/200 to 20/100 (42%). After prescription, the most common best corrected distant visual acuity is better than 20/25 (81%). The most common purpose to use low vison aids was book reading (57%). CONCLUSIONS: These results show that a application of New Head Mounted Visual Enhancement System will be a great help to increasing low vision populations for visual rehabilitation.
