Abstract

PURPOSE: To investigate the effects of age, sex, intraocular pressure (IOP), central corneal thickness (CCT), corneal curvature, anterior chamber depth (ACD) and axial length on OPA measurements using dynamic contour tonometer (DCT) in healthy subjects. MATERIALS-METHODS: Fifty-three eyes of 53 healthy individuals were included in this prospective study. After keratometric measurements, OPA and IOP were measured using Pascal DCT under topical anesthesia. The CCT was determined with the aid of ultrasonic pachymeter. After that, ACD and axial length of the subjects were measured by A scan ultrasonography. Pearson correlation analysis was used to determine the association between OPA and other parameters. RESULTS: The mean age of 53 subjects (34 female, 19 male) who were included in the study was 52,68 ± 8,29 years. Mean OPA was 2,81 ± 1,01 mm Hg. Mean IOP was 15,89 ± 2,39 mm Hg, corneal curvature was 7,80 ± 0,23 mm, CCT was 556,30 ± 32,80 µm, ACD was 2,91 ± 0,32 mm and axial length was 23,14 ± 1,10 mm. There was no correlation between OPA values and age, CCT or ACD of the subjects (p>0.05). There were significant negative correlations between OPA and axial length (p

Özet

AMAÇ: Bu çalışmanın amacı, sağlıklı insanlarda dinamik kontur tonometre (DKT) ile ölçülen oküler puls amplitüdün (OPA); yaş, cinsiyet, göz içi basıncı (GİB), santral kornea kalınlığı (SKK), korneal kurvatür, ön kamara derinliği (ÖKD) ve aksiyel uzunluk ile ilişkisi olup olmadığını araştırmaktır. GEREÇ-YÖNTEM: Bu prospektif çalışmaya 53 sağlıklı bireyin 53 gözü dahil edildi. Keratometri ölçümlerini takiben topikal anestezi altında Pascal DKT ile OPA ve GİB ölçümleri yapıldı. Ultrasonik pakimetre yardımıyla SKK saptandı. Daha sonra A scan ultrasonografi ile olguların ön kamara derinlikleri ve aksiyel uzunlukları ölçüldü. OPA ile bu parametreler arasında bir ilişki olup olmadığını araştırmak için Pearson korelasyon analizi kullanıldı. BULGULAR: Çalışmaya alınan 53 bireyin (34 kadın, 19 erkek) yaşları ortalaması 52,68 ± 8,29 yıl idi. Ortalama OPA 2,81 ± 1,01 mm Hg idi. Ortalama GİB 15,89 ± 2,39 mm Hg, korneal kurvatür 7,80 ± 0,23 mm, SKK 556,30 ± 32,80 µm, ÖKD 2,91 ± 0,32 mm ve aksiyel uzunluk 23,14 ± 1,10 mm idi. Olguların yaş, SKK ve ÖKD'si ile OPA değerleri arasında herhangi bir korelasyon tespit edilmedi (p>0.05). Aksiyel uzunluk ve korneal kurvatür ile OPA arasında anlamlı negatif bir korelasyon saptandı (sırasıyla p
