[Automobile driving capacity after retinal detachment surgery].
BACKGROUND
After vitreoretinal surgery the patient is at least temporarily unable to drive. Buckling procedures may cause refractive changes, reduced motility or impaired binocular vision. We examined the ability of these patients to drive a car according to German law after retinal surgery.


METHODS
The frequency and extent of changes interfering with driving ability were examined in 112 unselected patients 3.5 years (2-5 years) after successful buckling procedures. We used half-round buckling elements of 3-11 mm diameter or encircling bands (2-3 mm). We examined visual acuity, frequency of permanent diplopia and field of normal binocular vision. Driving ability was considered as impaired, when visual acuity was below 0.4 in the better eye or 0.2 in the worse eye, or when diplopia occurred within a gazing field of 20 degrees of diameter.


RESULTS
Eighteen of 112 (16%) patients reported diplopia within the first 3 months, so they were temporarily unable to drive. Two to five years later 14 of 112 patients did not have sufficient visual acuity according to the German requirements. Another 2 patients had an impaired binocular vision, resulting in driving disability.


CONCLUSIONS
Driving ability may be temporarily restricted by double vision in 15% of patients after successful buckling for retinal detachment. Permanent driving ability is mainly impaired by macular involvement in retinal detachment. The type of buckling procedure is of minor importance.
