Materials and Methods: Early proliferative Type II Diabetic drivers who have recently been scheduled for PRP procedure are included in the study. Complete ocular examination were performed for each patient. Pre- and post- treatment color vision and streopsis examinations were performed for each eye. The monoocular central 30- 2 and binocular Esterman perimetric tests using Model 750 Humphrey Visual Field Analyser II were performed before and 1 and 3 months after PRP, respectively.

Results: A total of 74 eyes of 37 patients, 16 females and 21 males were included in the study. The mean age of the patients was 41,8 ± 2,6 years (range, 36-47 years). Visual field defects which are not legally allowed for driving has been noted in 8 patients (% 24,2) at the first month exam upon examination with Esterman binocular visual field analysis, which all disappeared in the thirdmonth exams. There was a significant decrease in the mean retinal sensitivities of central visual field of the patients at the first post-laser month examination (p<0,05).

Conclusion: There has been an improvement in binocular and the monoocular visual fields of the PRP treated diabetic patients, who are under the risk of being revoked of their driving licence, three months after the treatment. These patients should be advised not to drive during the first month after the end of their PRP treatment. Keywords : Diabetes, Driving licence, Panretinal laser photocoagulation, Visual field
