Summary

Background: 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.
Aim: 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.
Methods: 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.
Results: 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.
Conclusion: 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.
