What type of retinopathy is likely to result in disqualifications?

Severe proliferative or unstable non-proliferative retinopathy is likely to result in disqualifications because it can significantly impact a person's vision and ability to drive safely. This type of retinopathy is characterized by abnormal blood vessel growth in the retina, which can lead to serious vision complications, including bleeding in the eye, retinal detachment, or severe vision loss. These vision impairments pose a direct risk when operating a commercial vehicle, where clear and reliable vision is crucial for safe driving.

In contrast, conditions such as minor non-proliferative retinopathy, stable retinopathy, and myopic retinopathy typically do not present the same level of risk to driving ability. Minor non-proliferative retinopathy often has minimal symptoms and is generally less likely to progress to a stage that would impair vision severely. Stable retinopathy indicates that the condition is not currently worsening, and myopic retinopathy, while it involves changes to the retina associated with high nearsightedness, usually does not lead to functional vision loss in many cases. Therefore, the severity and instability of proliferative retinopathy are key factors in disqualifying a driver.
