Complications after pars plana vitrectomy in diabetic patients in the early postoperative period
Purpose: To assess the frequency of serious postoperative complications in the three-month period after pars plana vitrectomy performed for pathological diabetic proliferative vitreoretinopathy. Setting: The set consisted of 90 eyes. The mean duration of diabetes in this set of patients amounted to 19 years. In 18 patients, type I diabetes was present, and 72 patients had type II diabetes. Methods: In all patients, 19-gauge pars plana vitrectomy [PPV] was performed; the patients were examined 1, 4, 8, and 12 weeks after the surgery. Their visual acuity was evaluated on ETDRS text charts, aplanation tonometry was performed, the anterior eye segment was examined with a slit lamp, and findings on the retina were evaluated using biomicroscopy and indirect ophthalmoscopy. Results: 1 case: closed angle secondary glaucoma was present with excessive oil filling. 1 case: the same type of glaucoma for excessive gas expansion, always with a forward shift of the lens and pupillary block development. 1 case: the preoperatively diagnosed rubeosis progressed and painful neovascular glaucoma developed. 5 cases: cataracta complicata was treated surgically. 1 case: vitreous cavity lavage was done for relapse of hemophthalmus. 4 cases: rhegmatous retinal detachment retina was diagnosed. 4 cases: traction-rhegmatogenous retinal ablation was observed. In 2 eyes, silicone oil was present in the anterior chamber, in contact with the corneal endothelium. Conclusions: Pars plana vitrectomy is an operation that can tackle complex findings connected with proliferative diabetic retinopathy. In our set, we observed serious postoperative complications endangering the patients’ vision in 21% of the operated eyes. We did not succeed in solving these complications in 7% of the eyes of the set.
