Correlation of Scheimpflug Densitometry Measurements of Corneal Haze With Disability Glare

Plain-language summary

Disability glare is described as "halos" or "starbursts" around bright sources of light that can cause discomfort and reduce vision. The cornea is the clear "window" at the front of the eye, but certain conditions such as a previous infection can leave a scar. Corneal scars can cause disability glare by scattering and spreading incoming light instead of allowing it to focus on the back of the eye (retina) to get a crisp image. In this study, the corneal scar will be analyzed using a new device that measures scar density (Pentacam), and a relationship with disability glare will be made. This can help us further understand disability glare and make better decisions in the future on when to treat these scars to help patients see better.
