Abstract

Purpose: To compare the optical coherence tomography (OCT) parameters of the retinal nerve fiber layer (RNFL) and optic nerve head (ONH) between primary open angle glaucoma (POAG) and primary angle closure glaucoma (PACG) patients followed up in our clinic. Materials and Methods: Prospectively between January 2006 and May 2006, smax, imax, savg, iavg, average thickness parameters for RNFL analysis; and disk diameter, disk area, cup area, rim area, vertical cup diameter parameters for ONH analysis with OCT were compared among 3 groups, i.e. PACG group (Group 1: 54 eyes of 27 patients), POAG group (Group 2: 54 eyes of 27 patients), and a control group (Group 3: 40 eyes of 20 patients). Results: Mean age of Groups 1-3 was respectively 61.7±9.9, 64±10, and 52±9.6. According to the OCT evaluation for Groups 1 and 2 between disk area (2.6±0.5, 2.4±0.4), rim area (1.1±0.5, 1.3±0.7), and cup area (1.2±0.5, 1.3±0.7) there was a statistically significant difference (p<0.05). When Groups 1 and 3 were compared smax (130.30±42, 182.78±157), savg (100.43±32, 125.59±18), iavg (108.31±34, 133.76±21), average thickness (83.40±23, 100.66±12), cup area (1.24±0.59, 0.58±42), and rim area (1.17±0.51, 1.74±0.55) were statistically significant. Moreover, all parameters were statistically significant when Groups 1-3 were compared. Conclusion: For the diagnosis and follow-up of POAG and PACG patients OCT is a valuable device for RNFL and ONH analyses. For comparison of these two groups in terms of glaucomatous optic nerve disease development steps, OCT yields helpful parameters.

Özet

Amaç: Kliniğimiz glokom bölümünde takipte olan primer açık açılı ve primer kronik kapalı açılı glokom hastalarının retina sinir lifi tabakası (RSLT) ve optik sinir başının (OSB) optik koherens tmografi (OKT) parametrelerinin karşılaştırılması. Gereç ve Yöntem: Geriye dönük olarak Ocak 2006-Mayıs 2006 tarihleri arasında takip edilen primer kapalı açılı glokom (PKAG) (1. grup; 27 hasta, 54 göz), primer açık açılı glokom (PAAG) (2. grup, 27 hasta, 54 göz) ve kontrol grubunun (3. grup, 20 hasta, 40 göz) OKT ile RNFL 3.4-analizinde; smax, imax, savg ve iavg (sırasıyla üst ve alt maksimum ve ortalama kalınlık), average thickness (ortalama kalınlık) ve optik sinir başı-Fast Optik Disk- analizinde; disk diameter (disk çapı), disk area (disk alanı), cup area (çanaklaşma alanı), rim area (rim alanı), vertical cup diameter (dikey çanaklaşma çapı) parametreleri karşılaştırıldı. Bulgular: Hasta gruplarının yaş ortalaması sırasıyla 61.7±9.9, 64±10, 60.3±10.6 idi. Gruplar arasında istatistiksel anlamlı fark bulunan parametreler; 1. ve 2. gurubun OKT değerlendirmesinde sırasıyla disk alanı: 2.6±0.5, 2.4±0.4; rim alanı: 1.1±0.5, 1.3±-0.7 ve cup alanı: 1.2±0.5, 1.3±0.7 idi (p<0.05). Birinci ve 3. grup karşılaştırıldığında sırasıyla smax: 130.30±42, 182.78±157; savg: 100.43±32, 125.59±18; iavg: 108.31±34, 133.76±21; ortalama kalınlık: 83.40±23, 100.66±12; cup alanı: 1.24±0.59, 0.58±42; rim alanı:1.17±0.51, 1.74±0.55 idi. İkinci. ve 3. grup karşılaştırıldığında ise tüm parametrelerde istatiksel anlamlı fark olduğu saptandı (p<0.05). Sonuç: PAAG ve PKAG hastalarının tanı ve takibinde OKT, optik sinir başı ve sinir lifi analizinde değerli bir yardımcıdır, ve bu iki grubun karşılaştırılmasında glokomatöz optik sinir hasarının gelişim basamakları açısından yardımcı parametreler vermektedir.
