Secondary complications in surgery of epiretinal membranes]

MATERIAL AND METHODS: Preoperative findings, intraoperative and postoperative complications as final results of 70 consecutive cases of idiopathic or secondary ERM operated by the same retina surgeon were analyzed. RESULTS: In all cases the ERMs were successfully removed from the fovea. The mean v.a. increased from 0.34 +/- 0.2. to 0.54 +/- 0.31, (p < 0.05) postoperatively. Idiopathic and secondary ERMs both showed significant improvement after surgery. Complications included intraoperative hemorrhage and retinal tears. Postoperative progressive nuclear sclerosis, retinal tears causing detachments, macular edema and retinal pigmentary epitheliopathy. CONCLUSIONS: Performing surgery for ERMs is worthwhile on eyes with major decreased v.a. and on eyes with metamorphopsia but only moderately reduced vision. Postoperative complications are frequent but can usually be managed successfully. Of them only retinal detachment is of some worse prognosis on the final functional outcome.
