Abstract

Aim: To compare the values of anterior chamber angle evaluated with fourier domain anterior segment optical coharence tomography (FD-ASOCT) after deep anterior lamellar keratoplasty (DALK) and penetrating keratoplasty (PK) in patients with keratoconus. Material and Method: The study includes 58 eyes of 47 patients who underwent DALK (14 patients) or PK (21 patients) and unoperated keratoconus (23 patients) subjects as control group. Skleral spur (SS) was defined manually and angle opening distance at 500 μm (AOD500) and trabeculo-iris space area at 500 μm (TISA500) were measured in all patients on same day by using FD-ASOCT. The results were compared within groups who underwent DALK, PK and control group (unoperated keratoconus patients). Results: The mean age was not significantly different between groups (p>0.05). The mean TİSA500 value in DALK group was 0.21±0.18 mm²; in PK group was 0.18±0.09 mm² and in keratoconus group was 0.18±0.05 mm². The TISA500 results were not significantly different between groups (p>0.05). The mean AOD500 value in DALK group was 569.43±312.11 μm; in PK group was 616.36±306.25 μm and in keratokonus group was 574.64±160.75 μm. The AOD500 results were not significantly different between groups (p>0.05).

Özet

Amaç: Keratokonus nedeniyle Derin Anterior Lameller Keratoplasti (DALK) ve Penetran Keratoplasti (PK) yapılmış olgularda Fourier Domain Ön Segment Optik Koherans Tomografi (FD-ÖSOKT) ile ölçülen açı değerlerinin karşılaştırılması. Gereç ve Yöntem: Çalışmaya keratokonus nedeniyle PK (14 olgu), DALK (21 olgu) uygulanmış ve kontrol grubu olarak opere olmamış keratokonuslu (23 olgu) 47 olgunun 58 gözü dahil edildi. Tüm olgulara aynı gün FD-ÖSOKT çekimi yapılarak sıklıkla standardize açı parametreleri olan 500 μm’de açı açılma mesafesi (AAM500) ve trabeküler-iris yüzey alanı (TİYA500) manuel olarak skleral mahmuz (SM) bulunmasıyla ölçüldü. Bulunan değerler keratokonus nedeniyle DALK ve PK uygulanmış olgular ve kontrol grubu arasında karşılaştırıldı. Bulgular: Grupların yaş ortalamaları arasında istatistiksel olarak anlamlı farklılık saptanmamıştır (p>0,05). DALK grubunda ortalama TİYA500 0,21±0,18 mm²; PK grubunda ortalama TİYA500 0,18±0,09 mm² ve keratokonus grubunda ortalama 0,18±0,05 mm² olarak bulundu. TİYA500 ölçümleri gruplara göre istatistiksel olarak anlamlı farklılık göstermemektedir (p>0,05). DALK grubunda ortalama AAM500 569,43±312,11 μm; PK grubunda ortalama AAM500 616,36±306,25 μm ve keratokonus grubunda ortalama 574,64±160,75 μm olarak bulundu. AAM500 ölçümleri de gruplara göre istatistiksel olarak anlamlı farklılık göstermemektedir (p>0,05). Sonuç: Keratokonus nedeniyle DALK ve PK olmuş olgularla opere olmamış olgular arasında açı yapıları değerlendirildiğinde farklılık saptanmamıştır.
