简要总结
The purpose of this study is to assess the vision improvement achieved by patients with retinal disorders who received corneal treatments by a low vision aid device.
详细描述
The purpose of this study is to assess the vision improvement achieved by patients with retinal disorders, including age-related macular degeneration and diabetic macular edema, who received corneal treatments by a low vision aid device. Patient records will be analyzed to determine measures of vision improvement including best spectacle-corrected distance visual acuity (CDVA). Analyses will include descriptive statistics and correlation between outcomes and baseline characteristics.

入选标准
- •Female or male
- •Patient is at least 50 years old
- •Patient has diagnosed retinal disorder that causes central vision loss in one or both eyes
- •Treated eyes, at time of treatment, were pseudophakic or phakic with no significant vision loss due to cataract
- •Patient had moderate to severe baseline vision impairment with CDVA of 20/63 or worse (decimal = 0.317 or less; logMAR greater than or equal to 0.50) in the treated eye(s)
- •Patient CDVA records are available at baseline and at 1m or longer post-Tx times
排除标准
