Overview

The objective of the retrospective ten-year investigation is to evaluate anatomicaland functional results of pars plana vitrectomy (PVV) in haemophthalmus (HE)after retinal venous occlusion (RVO), and to assess in detachment of the retina(DR) with HE after RVO, the part played by traction of the retina.In 32 patients the authors assessed anamnestic data , the finding before surgery,supplementary procedures of PPV, surgical and postoperative complications.In 12 eyes they indicated during PPV internal tamponade of the retina on accountof imminent or already developed DR: in 7 eyes using hexafluorosulphide(SF6) andin 5 yeyes silicone oil 5000 cts. A total of 5 eyes were reoperated on account of DR.In 12 eyes the authors recorded after PPV a rise of the intraocular pressure,short-term and temporary in 4 eyes and long-term in 8 eyes. The emulsified siliconeoil was drained in 5 eyes without further complications. A complicated cataractwas eliminated after PPV in 9 patients.The results were evaluated in 30 patients who attended the final examination. Thefinal mean vision was 0.21. In 23 eyes the visual acuity improved, in 5 it wasunchanged and in 2 eyes it deteriorated.Deterioration of the final vision wascaused in one eye by maculopathy and in one eye by penetration of silicone oilbeneath the retina.In a total of 12 eyes the authors diagnosed during PPV tractional DR. The optimaltime for indication of PPV in HE after RVO without signs of ischaemia in theanterior segment is six months after the development of HE when the risk ofadverse vitreoretinal traction is reduced to a minimum.
