Which conditions are typically included in a vision history review?

The inclusion of retinopathy, cataracts, aphakia, glaucoma, and macular degeneration in a vision history review is essential for understanding a driver’s eye health and potential impact on driving abilities. These conditions are significant because they can severely affect visual acuity, depth perception, and overall visual fields, which are critical for safe driving.

Retinopathy refers to damage to the retina that can lead to vision impairment, often associated with diabetes. Cataracts cause clouding of the lens, resulting in blurred vision. Aphakia, the absence of the lens of the eye, can significantly impair focus and clarity. Glaucoma is characterized by increased intraocular pressure that may damage the optic nerve, leading to vision loss. Macular degeneration results in the deterioration of the central portion of the retina, affecting sharp, central vision.

In a DOT physical, identifying these conditions is crucial as they can hinder a driver's ability to maintain safe control of a vehicle and to react promptly to road conditions or hazards. Monitoring and addressing these disorders allows for proper assessment of a driver’s fitness to operate a commercial vehicle, ensuring safety on the roads.
