Visual disorders and fitness for professional driving

The professional driver's post is a security post that requires a careful assessment of the visual functions influencing the medical fitness decision. Professional driving benefits from a codified regulation regarding vision disorders. However, it suffers from several shortfalls making the task of the occupational doctor sometimes difficult.

To identify the ophthalmological pathologies that have influenced the fitness decision for professional driving and develop a fitness approach for professional driving according to the different ophthalmological pathologies encountered.

We conducted a retrospective, descriptive study from the files of professional drivers with visual impairment who consulted the department of occupational health at Charles-Nicolle Hospital of Tunis for medical fitness decision, during the period from January 1, 2008 to December 31, 2016.

Sixty drivers were included in the study. The population gender was exclusively male. Mean age was 48 ± 8.43 years. A pathological medical history was found in 70% of patients, mainly represented by: Diabetes (37%) and high blood pressure (28%). Truck drivers were the most represented (45%) and the average of professional experience was 14 years with extremes ranging from zero to 33 years. In 75% of cases, patients had one or more functional complaints. The decrease in visual acuity was the common reason for consultation (55% of cases). Diabetic retinopathy was the ophthalmological diagnosis most commonly found in our study (18% of cases). Diabetic retinopathy was the leading cause of definitive disability in our study (32% of cases). Other ophthalmologic causes of definitive disability were: Glaucoma, amblyopia, homonymous haemianopia, age-related macular degeneration, blindness or functional loss of one eye, diplopia, retinal detachment and uveitis complicating Behcet's disease.

At the end of this study, we showed regulatory deficiencies for which we suggested recommendations that could help the occupational physician to take medical fitness decisions.
