LONG -TERM RESULTS FOLLOWING PNEUMATIC RETINOPEXY

Purpose: To evaluate the long-term outcome (> 6 years) following retinal reattachment by pneumatic retinopexy.
Methods: 78 eyes were examined retrospectively after treatment with pneumatic retinopexy. The average follow-up period was 6.4 years. Visual acuity was documented and fundus examination performed. Possible reoperations were evaluated. Visual acuity was compared to that of the fellow eye.
Results: In 77 eyes permanent reattachment of the retina was achieved. In 67 eyes the primary intervention had been successful. However, in 19.4% of these the retina redetached already during the first 3 months and in further 4.5% later during the observation period requiring reoperation. The average number of operations necessary to obtain permanent attachment of the retina in the 77 eyes was 1.39. One eye was lost due to phthisis bulbi and had to be enucleated. Six years after the first intervention visual acuity of the eyes without reoperation was 0.57 (±0.25 SD) with initially detached macula [fellow eye 0.67 (±0.27)] and 0.7 (±0.27) with attached macula [fellow eye 0.7 (±0.25)]. Visual acuity of the eyes with reoperation was 0.36 (±0.3) [fellow eye 0.51 (±0.29)] with initially detached macula and 0.64 (±0.26) [fellow eye 0.63 (±0.35)] with attached macula.
Conclusion: Six years after initial pneumatic retinopexy the retina was found to be attached in 98.7% of eyes. In 65.4% this result had been achieved by the minimally invasive primary surgery alone. The need for reoperation became evident already during the first 3 months in 89% of cases. Initial visual outcome was overall satisfactory.
