Purpose: The purpose of this paper is to assess the anatomic and functional results after macular surgery in a large group of patients.
Method: Between 06/1995 and 06/2002 423 eyes underwent vitreous surgery for macular holes (n=188) or macular pucker (n=235) with a standard pars plana vitrectomy (PPV) with induction of posterior vitreous separation, membrane peeling, peeling of the internal limiting membrane (no ICG staining was used) and gas (SF6-) instillation. In all patients circular peripheral cryoretinopexy was performed 3-4 weeks prior to the PPV. Anatomic results as well as visual acuity, also depending on postoperative complications and secondary surgical interventions, were investigated retrospectively with a follow up of 15.6 months on average (min 6 months).
Results: A second surgical intervention due to vision threatening complications after PPV had to be performed in 12/423=2.6% in the immediate postoperative period. Anatomic and functional results are reported in 297/423=70.2% eyes. Hole closure of macular holes was obtained in 93.3%, visual acuity improved from preop 0.2 to postop 0.4. In the macular pucker group metamorphopsias improved in 46.6%; visual acuity improved from preop 0.3 to postop 0.5.
Conclusions: In our group a second vitreoretinal procedure due to vision threatening complications had to be performed in 2.6%. This is lower than in many other studies with comparable anatomic
