[Comparative investigation of the etiology of XXXX after epimacular surgery].

@entity1 @entity1020 @entity227
BACKGROUND: Sectorial @entity227 after macular hole surgery were described by several authors. The intraocular gas tamponade is discussed to be a possible causative factor for this complication. @entity1 AND METHODS: Goldmann perimetry and threshold perimetry were performed preoperatively and 6 weeks postoperatively in 48 @entity1 who underwent epimacular surgery because of @entity1020 (23 eyes) or macular holes stage II - IV (25 eyes). Laser polarimetry was performed additionally using the Nerve Fiber Analyzer. The results were compared quantitatively. In all cases an epimacular membrane was peeled off. Eyes with macular holes underwent fluid-gas exchange with SF 6 without drying up the retina completely. RESULTS: No @entity1 showed a sectorial @entity227 . The quantitative comparison of visual field examinations did not prove a difference between both groups. CONCLUSIONS: We could not detect any impairing influence of the intraocular gas tamponade in our @entity1 . Without complete desiccation of the vitreous cavity, @entity227 after macular hole surgery are unlikely.
