Background: This study was performed to investigate if long-term visual results and complication rates of buckling surgery in myopic eyes of different degree differ from those in emmetropic eyes.

Patients and Methods: From the files of the Dept. of Ophthalmology Kiel all myopic patients were selected who had had buckling surgery for retinal detachment during 1990 and 1991. All patients under the age of 18, and with previous retinal diseases and surgery as well as general diseases were excluded. The remaining 42 eyes of 41 patients were re-examined. All eyes of this study group (SG) were divided into 3 subgroups of myopia: low: -1.0 to -2.75 D, medium: -3.0 to -5.75 D, high: > -6.0 D. 42 emmetropic eyes after buckling surgery served as a control group (CG). The average follow-up was 78.2 months (range: 56-106 months).

Results: Initial re-attachment rate was 88,1 % in the SG 92.9 % and in the CG. After one reoperation the retina was attached in all eyes of both groups. During follow-up re-detachment of the retina developed in 3 eyes (7%) in each group. Whereas only one reoperation was needed in the CG to permanantly reattach the retina, 13 operation had to be performed in the SG, 8 of these operations in the high myopic subgroup. In 2 eyes of this group the retina was not attached at the end of follow-up. In the SG in 54.8 % visual acuity (V.A.) improved by 2 lines or more, 23.8 % had the same V.A., and in 21.4 % V.A. deteriorated. There were no statistical differences between the different subgroups in myopic eyes. Corresponding V.A. results of the CG were 73.8 %, 21.4 %, and 4.8 %, respectively.

Conclusions: In the long-term course high myopic eyes have a higher risk of redetachment of the retina after initial successful buckling surgery than low or medium degree myopic eyes as well as emmetropic eyes. In respect to postoperative vision results there is no correlation to the degree of myopia.
