Abstract

Purpose: To evaluate the morphological changes on the anterior segment using ultrasonic biomicroscopy imaging (UBM) in phakic patients who underwent 23 Gauge pars plana vitrectomy (PPV) for variety of vitreoretinal pathologies including vitreous hemorrhage, rhegmatogenous retinal detachment, proliferative diabetic retinopathy with either silicone oil or gas (C3F8) tamponade. Methods: Patients were divided into 2 groups based on the internal tamponade used: group 1 (silicone oil, n=21), group 2 (C3F8, n=20). Several anterior segment variables including lens thickness, scleral thickness (ST), anterior chamber depth (ACD), trabecular mesh- work-iris angle (TIA), ciliary body thickness (CBT), trabecular meshwork-ciliary process distance (T-CPD), and iris-ciliary process distance (I-CPD) were assessed before the surgery and at post-operative week 1. Results: Mean ACD, TIA, CBT, T-CPD, and I-CPD were signifi cantly decreased in group 2 compared to baseline; whereas there was no signifi cant change in these parameters in group 1 after the surgery. Mean LT and ST were signifi cantly increased in group 1 compared to baseline and there was no signifi cant change in these parameters in group 2 after the surgery. Conclusion: Gas tamponade may cause signifi cant morphological changes in the anterior segment structures in the supine position.

Özet

Amaç: Vitreus hemorajisi, yırtıklı retina dekolmanı, proliferatif diabetik retinopati gibi değişik vitreoretinal patolojilerde 23 Gauge pars plana vitrektomi yapılan fakik olgularda ultrasonik biyomikroskop kullanarak ön segment morfolojik değişimini değerlendirmek amaçlanmıştır. Gereç ve Yöntem: Hastalar internal tamponat kullanımına göre; Grup 1 (Silikon yağı, n=21) ve Grup 2 (C3F8, n=20) olarak 2 gruba ayrıldı. Ön segment parametrelerinden lens kalınlığı (LK), ön kamera derinliği (ÖKD), trabeküler ağ-iris açısı (TİA), sklera kalınlığı (SK), siliyer cisim kalınlığı (SCK), trabeküler meshvork-siliyer proçes mesafesi (T-SPM), iris-siliyer proçes mesafesi (I-SPM) ameliyat öncesi ve postoperatif 1. haftada değerlendirildi. Bulgular: Grup 2’de; ortalama ÖKD, TİA, SCK, T-SPM ve İ-SPM ameliyat öncesine göre sonrası önemli derecede azalma gösterirken, Grup 1’de önemli derecede değişiklik gözlenmedi. Grup 1’de ortalama LK ve SK operasyon öncesine göre anlamlı artış gösterirken, Grup 2’de anlamlı artış saptanmadı. Sonuç: Gaz tamponatlar supin pozisyonda, ön segment yapılarında önemli derecede değişikliğe sebep olabilirler.
