Abstract

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.

Özet

Amaç: Pars plana vitrektomi (PPV)+silikon yağı enjeksiyonu (SYE) yapılan olgularda cerrahi sonrası göz içi basınç (GİB) artışı nedenleri ve tedavi yaklaşımlarını incelemek. Gereç ve Yöntem: PPV+SYE uygulanmış 134 olgunun 134 gözü çalışmaya dahil edildi. Olguların 87’si erkek, 47’si kadındı. Olguların eşlik eden sistemik hastalıkları, ameliyat öncesi, ameliyat sırasında ve ameliyat sonrası bulguları ve uygulanan tıbbi tedaviler retrospektif olarak incelendi. Ameliyat sonrası 1 ay süresince GİB 22 mmHg üzerinde olan vakalar değerlendirmeye alındı. GİB’ı yüksek olan olgular 4 grup altında incelendi: Grup 1 pupiller blok ile birlikte açı kapanması glokomu, Grup 2 pupiller blok olmaksızın açı kapanması glokomu, Grup 3 ön kamarada (ÖK) silikon mevcudiyetine bağlı açık açılı glokom, Grup 4 ÖK’da silikon olmaksızın açık açılı glokom. Uygulanan tedaviler, tedavi öncesi ve sonrası GİB değerleri kaydedilerek sonuçlar t-testi ile değerlendirildi. Bulgular: Ortalama tanı yaşı 49.4±13 yaş (15 ila 80 yaş arası) idi. PPV+SYE sonrası 56 olguda (%41.79) GİB yüksekliği saptandı. Olguların gruplara dağılımı: Grup 1: 4 (%3), Grup 2: 2 (%1.5), Grup 3: 22 (%16.4), Grup 4: 28 (%20.9) olgu idi. Ameliyat sonrası dönemde GİB yüksekliğinin ortaya çıkış süresi ortalama 26 gün (2-118 gün ) olup ortalama GİB’ı 37.5±15.6 mmHg idi. GİB artışı gelişen 56 olgunun 48’inde GİB’ı topikal (beta bloker, dorzolamid) ve/veya sistemik tedavi (asetozolamid) ile kontrol altına alındı (17.5±2.12 mmHg). Medikal tedaviye cevap vermeyen 7 olguya silikon yağı çıkarımı uygulandı. Silikon yağı çıkarımından sonra bir olgu hariç tüm olgularda GİB tıbbi tedavi ile kontrol altına alındı. Sonuç: SYE sonrası gelişen GİB yüksekliği antiglokomatöz tedaviye iyi yanıt vermektedir. Maksimum medikal tedaviye yanıt vermeyen olgularda öncelikle silikon çıkarımı uygulanmalı, bu tedaviye yanıt vermeyen olgularda filtran cerrahi tercih edilmelidir.
