Eye Conditions

In general eye problems can be divided into two main groups, optical and medical.

  • Optical correction of vision relates to using glasses or contacts to correct near or far-sightedness.
  • Medical problems like cataract, glaucoma and macular degeneration, constitute a much broader category.

The links on the right side of the page contain the following information:

Eye Information

This section summarizes the results from selected major studies as follows:

Rates of Eye Disease presents data on the frequency of specific eye diseases in the US.

The Age Related Eye Disease Study (AREDS) looks at the use of antioxidant vitamins in slowing the progress of Macular Degeneration.

The Ocular Hypertension Treatment Study (OHTS) looks at the which risk factors, pressure level, disc shape, corneal thickness, etc., are helpful in predicting the development of Glaucoma in people who have elevated eye pressures.

Glaucoma Beyond OHTS describes the European Glaucoma Prevention Trial published in 2007. And as a follow-up there is an analysis of the combined data from those two studies, giving a refined risk model from a larger population base.

Eye Photos is a collection of photos with explanatory descriptions and diagrams.
