Advantages:

To analyze functional limits und subjective disturbances despite of anatomically successful surgery for rhegmatogenous retinal detachment (RRD).

Methods:

138 eyes with rhegmatogenous retinal detachment (RRD) were studied. Among others, analysis included VA measurement, recording of subjective VA disturbances, binocularity and stereopsis tests, pre- and postoperative macular assessment by OCT imaging, comparative fundus photography.

Effectiveness/safety:

Postoperatively, macular restoration occurred rapidly. Early macular edema was seen in 7% only. No eye showed macular pucker formation. Despite of significant visual improvement, 7% of patients complained of metamorphosia. Stereopsis was reduced in 40%. 10% perceived diplopia, usually associated with a decompensated exophoria or a vertical deviation. A slight retinal shift, usually downwards, was found in some eyes and explained vertical double images. In the later postoperative course these findings slowly, but incompletely improved.

Take home message:

The surgeon should be aware of functional deficiencies that may occur despite of a high primary reattachment rate and bother patients more than expected.
