Abstract Details

Purpose:

The evaluation of color sensitivity in patients with various ocular diseases causing in many cases low vision, as an indicator of the progression of the disease.

Setting:

Laboratory of Experimental Ophthalmology, Aristotle University of Thessaloniki

Methods:

Laboratory of Experimental Ophthalmology, Aristotle University of Thessaloniki

Results:

The reduction in blue-yellow color has been described in cataract, age-macular degeneration, diabetic retinopathy and glaucoma. During cataract progression visual function is affected and the perception of color can be altered. It has been described that sensitivity to color contrast is in some causes compromised causing contours, shadows and colors seem less vivid. Furthermore, there is evidence that reduced oxygen saturation of the retina is associated with reduction in color vision in diabetic patients. It also appears to be a correlation between the loss of a specific wavelength and the severity of diabetic macular edema.

Conclusions:

Color vision is a parameter that is significantly affected in patients with various diseases and color testing is an important tool for their evaluation.
