Abstract

Purpose: To identify differences in corneal biomechanical properties between healthy and pigment dispertion syndrome patients. Materials and Methods: Thirty eyes of 15 PDS (Group 1) and fifty eyes of 25 healthy (Group 2) subjects were included. Each participant underwent a complete ophthalmologic examination. Corneal biomechanical parameters; corneal-compen- sated IOP (IOPcc), Goldmann equivalent IOP (IOPg), corneal resistance factor (CRF), corneal hysteresis (CH) and central corneal thickness (CCT) were measured using an ocular response analyzer (ORA). The differences in ORA parameters between study and control group participants were analyzed using Student t test. A p value less than 0.05 was considered statistically significant. Results: In PDS patients and healthy subjects mean IOPcc values were 16.4±3.0 mmHg and 17.2±3.6 mmHg respectively (p=0.135). IOPg values were 15.09±3.3 mmHg and 15.88±3.6 mmHg respectively (p=0.259), CRF values were 9.66±1.8 mmHg and 9.84±1.8 mmHg respectively (p=0.948), CH values were 9.66±1.5 mmHg and 9.60±1.7 mmHg respectively (p=0.592), CCT values were 552.6±52.6 μm and 537.3±38.5 μm respectively (p=0.054). No significant difference was found between two groups. Conclusions: Pigment deposits of cornea endothelium do not affect corneal biomechanical properties in PDS patients.

Özet

Amaç: Pigment dispersiyon sendromlu gözlerde Oküler Response Analizörü (ORA) ile ölçülen korneanın biyomekanik pa- rametrelerinin normal bireyler ile karşılaştırılması. Gereç ve Yöntem: Pigment dispersiyon sendromu (PDS) olan 15 hastanın 30 gözü (grup 1) ve kontrol grubu olarak 25 hastanın 50 gözü (grup 2) çalışma kapsamına alındı. Tam oftalmolojik muayene sonrasında ORA ile kornea düzeltmeli göz içi basıncı (GİBkk), Goldmann ile uyumlu göziçi basıncı (GİBg), korneal rezistans faktör (KRF), korneal histerezis (KH) de- ğerleri ve santral kornea kalınlıkları (SKK) kaydedildi. Verilerin istatistiksel analizinde Student t-testi kullanıldı. p<0.05 değeri istatistiksel olarak anlamlı kabul edildi. Bulgular: PDS li olguların ve sağlıklı olguların ortalama GİBkk değerleri sırasıyla 16.4±3.0 mmHg ve 17.2±3.6 mmHg idi (p=0.135). GİBg değerleri sırasıyla 15.09±3.3 mmHg ve 15.88±3.6 mmHg (p=0.259), KRF değerleri sırasıyla 9.66±1.8 mmHg ve 9.84±1.8 mmHg (p=0.948), KH değerleri sırasıyla 9.66±1.5 mmHg ve 9.60±1.7 mmHg (p=0.592), SKK değerleri sırasıyla 552.6±52.6 μm ve 537.3±38.5 μm idi (p=0.054). İki grup arasında istatistiksel olarak anlamlı bir fark izlenmemiştir. Sonuç: Pigment dispersiyon sendromu olan hastalarda kornea endotelinde biriken pigment hücreleri korneanın viskoelas- tik özelliklerini etkilememektedir.
