Abstract

Purpose: To compare the intraocular pressure values of Diaton transpalpebral tonometer (DTT) with those of the Goldmann applanation tonometer (GAT) and Canon TX-F noncontact tonometer. Materials and Methods: 103 eyes of 52 normal individuals not applied any intraocular or upper eyelid surgery and not diagnosed as glaucoma or did not use any glaucoma drugs, were included the study. After first observer made the measurement with Canon TX-F, second and third observers performed DTT and GAT, respectively with 15 minutes interval. Central corneal thickness of the each participant was measured by ultrasound pachymetry (Heidelberg Engineering IOPac, Canada). The corrected GAT values (D-GAT) were calculated according to the corneal thickness. The D-GAT and the other two devices values were compared with ANOVA and Pearson correlation analysis, the dual comparisons were made with t test. Results: Canon TX-F values were 1.02±3.40 mmHg higher than D-GAT values, and DTT values were 0.83±3.53 and 1.85±3.69 mmHg lower than D-GAT and Canon TX-F values, respectively. Canon TX-F values shown excellent correlation with D-GAT values (r=0.549, p<0.001), and there were moderate correlations between DTT and D-GAT values (r=0.430; P<0.001), and between DTT and Canon TX-F values (r=0.455; P<0.001). Conclusions: DTT can be useful especially for IOP measurement in the corneal pathologies, but it could make lower measurements than GAT must not be forgotten. Although Canon TX-F is seen as a safe device for normotansive cases, it made higher measurements than GAT must be kept in mind.

Özet

Amaç: Diaton transpalpebral tonometrenin (DTT) göz içi basıncı (GİB) değerlerini Goldmann aplanasyon tonometre (GAT) ve Canon TX-F non-kontakt tonometresi ile karşılaştırmak. Gereç ve Yöntem: Daha önce göz içi veya üst kapak cerrahisi geçirmemiş ve glokom tanısı ile anti-glokomatöz ilaç kullanmamış 52 normal bireyin 103 gözü çalışmaya alındı. Birinci araştırmacı Canon TX-F ile GİB ölçümü yaptıktan sonra 15’er dakika arayla, ikinci araştırmacı DTT ile ve üçüncü araştırmacı ise GAT ile ölçüm yaptı. Ayrıca her katılımcının santral kornea kalınlıkları (SKK) ultrasonik pakimetre (Heidelberg Engineering IOPac, Kanada) ile ölçüldü. Düzeltilmiş-GAT (D-GAT) değeri SKK’na göre düzeltilerek hesaplandı. D-GAT değeri ile diğer iki cihazın değerleri ANOVA ve Pearson korelasyon analizi, ikili karşılaştırmalar ise t testi ile değerlendirildi. Bulgular: Canon TX-F değerleri D-GAT değerlerinden ortalama 1.02±3.40 mmHg yüksek iken (p<0.05); DTT değerleri D-GAT değerlerinden 0.83±3.53 mmHg, Canon TX-F değerlerinden ise 1.85±3.69mmHg düşük idi (p<0.05). Canon TX-F ile D-GAT değerleri arasında çok iyi bir korelasyon var iken (r=0.549, p<0.001); DTT ile D-GAT ve Canon TX-F değerleri arasında orta derecede bir korelasyon (r=0.430, r=0.455, p<0.001) vardı. Sonuç: DTT, özellikle kornea patolojilerinde GİB ölçümünde yararlı olabilir ancak GAT’ne göre düşük ölçüm yaptığı unutulmamalıdır. Canon TX-F normotansif olgular için güvenilir bir cihaz olarak görünmekle birlikte GAT’a göre yüksek ölçümler yaptığı akılda tutulmalıdır.
