PURPOSE: In the majority of patients with full-thickness macular hole, closure can be achieved with vitreoretinal surgery techniques. However, postoperative function is variable and the prognostic determinants for visual acuity are incompletely understood. We evaluated the incidence and extent of macular edema after macular foramen surgery with and without combined cataract-surgery. METHODS: Between October 1997 and March 2001 macular foramen surgery was performed in 125 eyes from 116 patients. Fluorescein angiograms with sufficient quality were obtained from 59 eyes using a confocal scanning laser ophthalmoscope (Heidelberg Retina Angiograph, HRA, Heidelberg Engineering, Heidelberg) and were evaluated by two independent observers. RESULTS: Angiographic macular edema was noted on average 4.2 months after the operation in 47 out of 59 (79.7%) eyes. The incidence of macular edema was 87% in eyes after a combined cataract operation compared to 66.7 % in eyes with no simultaneous operation ( p=0.735). Mean postoperative visual acuity was 0.4 (min 0.1-max 1.2) with no significant difference between eyes with (4.1 lines) and without macular edema (3.5 lines) with regard to visual improvement from baseline. CONCLUSIONS: The results indicate a high incidence of macular edema in eyes after macular hole surgery with subsequent anatomical success. Apparently, the presence of macular edema is not associated with short term visual impairment. Furthermore it seems that a combined cataract operation compared to a consecutive procedure is not associated with disadvantages regarding the functional outcome.
