Abstract

The effects of variations in corneal curvature (CC) and keratoconus on intraocular pressure (IOP) measurements with non-contact tonometer (NCT) and Goldmann applanation tonometer (GAT) were investigated. No difference was observed between IOPs measured by NCT and GAT in 38 emmetropic and 42 astigmatic eyes with a corneal curvature difference less than 0.2 mm. Average IOP value of 36 eyes of 20 individuals with keratoconus was 6.7 ± 4.4 (range 1-18) mm Hg by NCT and 9.6 ± 3.5 (range 2-16) mm Hg by GAT (p

Özet

Kornea eğrilik yarıçapı (KEY) farklılıkları¬nın ve keratokonüsün Goldmann aplanasyon tonometresi (GAT) ve non-kontakt tonometre (NKT) ile göziçi basıncı (GİB) ölçüm sonuçlarına etkisi araştırıldı. Otuzsekiz emetrop ve KEY farkı 0.2 mm'nin altında olan 42 astigmat gözde NKT ve GAT 'si ile GİB ölçüm sonuçları arasında fark gö¬rülmedi. Yirmi bireyin 36 keratokonüslü gözünde ise GİB değerleri ortalaması, NKT ile 6.7±4.4 (1-18) mm Hg, GAT ile 9.6 ± 3.5 (2-16) mm Hg olarak bulundu (p 7 mm olan grupta ise NKT ile GİB ortalama 7.9 ± 4.7 (2-18) mm Hg, GAT ile 10.2 ±3.8 (2-16) mm Hg idi (p < 0.05). Düşük KEY değerlerinde her iki tonometri yöntemi ile GİB'nin düşük olarak ölçül¬düğü, ancak NKT'de bunun daha fazla olduğu sonucuna varıldı.
