Purpose: To evaluate the reasons of intraocular pressure elevation following pars plana vitrectomy (PPV) and silicone oil injection (SOI), and to assess the treatment modalities.

Materials and Methods: One-hundred thirty four eyes of 134 patients who underwent PPV+SOI were enrolled in this study. Demographic characteristics, systemic diseases, preoperative, intraoperative and postoperative findings, and systemic medications were recorded retrospectively. Patients who had IOP>22 mmHg lasting one month postoperatively were included. Paitents who had elevated IOP were grouped as follows: Group 1 angle closure glaucoma with papillary block, Group 2 angle closure glaucoma without papillary block, Group 3 open angle glaucoma due to silicone oil in the anterior chamber (AC), Group 4 open angle glaucoma without silicone oil in the AC. Student t-test was used in order to analyze the difference between preoperative and postoperative intraocular pressure, and number of medications used.

Results: Mean patient age was 49.4±13 years (range 15 - 80 years). IOP elevation was detected in 56 patients (41.79 %) following PPV+SOI. Patients were grouped as follows: Group 1: 4 (3%), Group 2: 2 (1.5%), Group 3: 22 (16.4%), Group 4: 28 (%20.9) Postoperative mean time of IOP elevation development was 26 days (range: 2-118 days) and mean IOP was 37.5±15.6 mmHg. The IOP rise in 48 of the 56 patients was controlled with topical and/or systemic medical treatment (17.5±2.12 mmHg). Silicone oil removal was performed to 7 patients in whom medical treatment failed. After silicone oil removal, the glaucoma persisted in only one case.

Conclusions: Intraocular pressure rise following PPV+SOI responses well to medical treatment. First of all, topical and /or systemic aqeous humour suppressants should be preferred. Silicone oil removal and filtering surgery should be performed to the cases who do not respond to maximum medical therapy.
