Abstract

Purpose: To determine the agreement between the measurements of intraocular pressure (IOP) by two portable tonome ters at patients with cornea pathology who were requiring contact lens usage. Material and Methods: IOP measurements of 64 eyes without eye pathology except refraction error have been recorded before contact lens wearing and after 5 minutes with both devices. Tono-Pen XL measurements were done after 15 minutes following I-Care tonometer measurements. T test, Pearson correlation analysis and Blant&Altman analysis were used for statistical evaluation. Results: Statistically significant difference were determined between measurements with and without contact lens (p<0.05). The results of measurements with I-Care were higher +2.07±3.38 mmHg than Tono-Pen XL and I-Care measurements with contact lens were higher +2.67±3.30 mmHg than Tono-Pen XL with contact lens (p<0.05). When we compare two device measurements separately; while there were no statistically significant difference between I-Care measurements with and without contact lens, Tono-Pen XL measurements showed statistically significant difference. Tono-Pen XL measurements with contact lens were lower 1.23±2.98 mmHg averagely than measurements without contact lens. While there was a good correlation between I-Care and Tono-Pen XL; I-Care and I-Care with contact lens and Tono-Pen XL and Tono-Pen XL with contact lens measurements (r=0.519, r=0.670, r=0.603 p<0.0001). Conclusion: Although both devices can be used for IOP measurements with contact lens, I-Care tonometer can be preferred due to absent of significant difference between measurements with and without contact lens.

Özet

Amaç: Kontakt lens (KL) kullanmayı gerektirir kornea patolojili hastalarda, hasta başı göz içi basınç (GİB) ölçümlerinde, taşınabilir iki tonometri ile elde edilen GİB değerlerinin uyumluluğunu karşılaştırmak. Gereç ve Yöntem: Refraksiyon kusuru dışında göz patolojisi bulunmayan 64 gözün KL takılmadan ve takıldıktan 5 da kika sonra her iki cihazla GİB değerleri ölçüldü. I-Care tonometri ile yapılan ölçümlerden 15 dakika sonra Tono-Pen XL ile yapılan ölçümlere geçildi. İstatistik değerlendirmesinde, ikili karşılaştırmalar t testi ile; ölçüm metotları arasındaki kore lasyon, Pearson korelasyon analizi ile, GİB farklarının dağılımı Blant&Altman analizi ile değerlendirildi. Bulgular: KL’li ve KL’siz her iki cihazla yapılan GİB değerleri arasında anlamlı fark vardı (p 0.05), Tono-Pen XLve KL-Tono-Pen XL değerleri arasında anlamlı bir fark vardı (p<0.05). KL-Tono-Pen XL değerleri, Tono-Pen XL değerlerinden ortalama 1.23±2.98 mmHg daha düşüktü. I-Care ve Tono-Pen XL; I-Care ve KL-I- Care; Tono-Pen XL ve KL-Tono-Pen XL değerleri arasında çok iyi bir korelasyon vardı (r=0.519, r=0.670, r=0.603 p<0.0001). Sonuç: Her iki cihazda KL üzerinden GİB ölçümlerinde kullanılabilir. Ancak I-Care ile elde edilen KL’li ve KL’siz GİB değerleri arasında anlamlı fark bulunmaması nedeniyle I-Care tonometri öncelikli tercih edilebilir.
