The medical examiner should refer a driver for a specialist evaluation for all of the following conditions except:

The decision to refer a driver for a specialist evaluation hinges on the potential impact of their condition on driving abilities. Conditions such as retinopathy, cataracts, and macular degeneration can significantly impair visual acuity and processing, which are critical for safe driving. These conditions often involve the retina or lens of the eye and can lead to severe visual limitations that necessitate a thorough assessment by an ophthalmologist or specialist to determine fitness for driving.

In contrast, conjunctivitis is an inflammation of the conjunctiva, typically characterized by redness and irritation of the eye. While it can cause discomfort and temporary vision disturbances, it is often a mild condition responsive to treatment, such as antibiotics or antihistamines, and typically does not pose a long-term threat to visual function. Thus, it generally does not require a referral to a specialist for evaluation concerning driving safety.

This distinction is important for medical examiners to ensure that they properly assess and manage conditions that could impair a driver's ability to operate a vehicle safely.
