🎯
Objective & Hypothesis:Purpose: To compare the anterior segment parameters of the two eyes in cases with asymmetric primary open-angle glaucoma (POAG) or ocular hypertension (OHT) by noncontact biometer (Haag-Streit LENSTAR® LS 900 Optical Biometer Switzerland) using optical low-coherence reflectometry.Materials and Methods: Cases who had been recently diagnosed as asymmetric POAG or OHT with the differences of intraocular pressure (IOP) >=5 mmHg and/or vertical cup to disc (c/d) ratio >=0.2 between their two eyes, were investigated prospectively.
📊
Key Findings & Data:Central corneal thickness (CCT), anterior chamber depth (ACD), axial length (AL) and lens thickness (LT) measurements of their two eyes were measured by optical biometer (Haag-Streit LENSTAR® LS 900 Optical Biometer) before anti-glaucoma treatment and compared statistically.

Abstract

Purpose: To compare the anterior segment parameters of the two eyes in cases with asymmetric primary open-angle glaucoma (POAG) or ocular hypertension (OHT) by noncontact biometer (Haag-Streit LENSTAR® LS 900 Optical Biometer Switzerland) using optical low-coherence reflectometry.Materials and Methods: Cases who had been recently diagnosed as asymmetric POAG or OHT with the differences of intraocular pressure (IOP) >=5 mmHg and/or vertical cup to disc (c/d) ratio >=0.2 between their two eyes, were investigated prospectively. Central corneal thickness (CCT), anterior chamber depth (ACD), axial length (AL) and lens thickness (LT) measurements of their two eyes were measured by optical biometer (Haag-Streit LENSTAR® LS 900 Optical Biometer) before anti-glaucoma treatment and compared statistically. Mann-Whitney U test was used for statistical analysis.Results: Thirteen female and 16 male totally 29 cases (12 cases with OHT and 17 cases with POAG with a mean age of 53.8±8.9) were included to the study. No significant differences were found between the CCT (p=0.89), ACD (p=0.87), AL (p=0.74) and LT (p=0.56). In 26 cases IOP and the other glaucomatous findings were controlled by medical treatment while in 3 cases filtering surgeries were performed. Conclusions: The anterior segment parameters were found to have no direct effects on initial asymmetric clinical findings of the two eyes in cases with POAG and OHT.

Özet

Amaç: Asimetrik başlangıçlı primer açık açılı glokom (PAAG) ve oküler hipertansiyon (OHT) olgularında, her iki gözün optik biyometri ile ölçülen ön segment parametrelerinin kıyaslanması amaçlandı. Gereç ve Yöntem: İki göz arasında en az 5 mmHg göz içi basıncı (GİB) ve/veya en az 0,2 düzeyinde vertikal çukurluk/disk (c/d) oranı farkı saptanarak teşhisleri yeni konulan PAAG ve OHT olguları ileriye dönük olarak incelendi. Olguların, GİB ve/veya c/d oranının daha yüksek olduğu ve diğer gözlerinin merkezi kornea kalınlığı (MKK), ön kamara derinliği (ÖKD), aksiyel uzunluk (AU) ve lens kalınlığı (LK) değerleri optik düşük koherens reflektometri yöntemi ile çalışan optik biyometri (Haag-Streit LENSTAR® LS 900 Optical Biometer) ile herhangi bir antiglokomatöz ilaç başlanmadan önce ölçüldü. Her iki göz arası farklılıklar Mann-Whitney U testi ile istatistiksel olarak analiz edildi.Bulgular: 12 OHT ve 17 PAAG toplam 29 olgu (13 kadın, 16 erkek, yaş ortalaması:53.8±8.9) çalışma kapsamına alındı. Klinik olarak daha kötü ve daha iyi başlangıçlı gözlerde, MKK (p=0.89), ÖKD (p=0.87), AU (p=0.74) ve LK (p=0.56) açısından anlamlı farklara rastlanmadı. 26 olguda GİB tıbbi tedavi ile kontrol altına alınırken, 3 göze filtran cerrahi uygulandı.Sonuç: PAAG ve OHT'lu olgularda ön segment parametrelerinin, hastalığın her iki gözde asimetrik başlangıcı üzerine doğrudan etkileri olmadığı sonucuna gidildi.
