Intraocular Pressure Measurements with Pneumotonometer and Tono-Pen in Patients Using Topical Antiglaucomatous Medication Due to Primary Open Angle Glaucoma
Öz
Purpose:To compare intraocular pressure (IOP) measurements obtained with Goldmann applanation tonometer (GAT), pneumotonometer, and Tono-pen in patients using topical antiglaucomatous medication due to primer open angle glaucoma.
Patients and Methods:The medical documents of patients using topical antiglaucomatous medication due to primary open angle glaucoma were retrospectively investigated in this non-randomized case-control study. Only right eyes of 113 patients were included. The IOP measurements obtained with pneumotonometer and Tono-Pen were statistically compared with the IOP measurements obtained with GAT, and the correlations between series were investigated.
Results:The mean age was 57.41 11.02 years (41 – 82 years) in 113 patients, 52 males and 61 females (p = 0.638). The mean IOP was 21.04 5.40 mmHg (12 – 46 mmHg) with GAT, 20.19 5.61 mmHg (12 – 48 mmHg) with pneumotonometer and 17.37 4.99 mmHg with tonopen (8 – 44 mmHg). The mean IOP values obtained with both pneumotonometer and tonopen were significantly lower than the mean IOP obtained with GAT (p <0.001 for both). IOP measurements obtained with both pneumotonometer (r = 0.96 and p <0.001) and tonopen (r = 0.83 and p <0.001) were significantly correlated with IOP measurements obtained with GAT.
Conclusion:IOP measurements obtained with pneumotonometer and tonopen in patients using topical antiglaucomatous medication due to primer open angle glaucoma is lower and correlated with the measurements obtained with GAT.

Topikal Antiglokomatöz İlaç Kullanan Primer Açık Açılı Glokom Olgularında Pnömotonometre ve Tonopen ile Göz İçi Basıncı Ölçümü
Öz
Amaç:Primer açık açılı glokomu olan ve topikal antiglokomatöz ilaç kullanan hastalarda Goldmann aplanasyon tonometrisi (GAT), pnömotonometre ve tonopen ile elde edilen göz içi basıncı (GİB) ölçüm sonuçlarını karşılaştırmak.
Hastalar ve Yöntem:Randomize olmayan, olgu kontrol çalışmasında primer açık açılı glokomu olan ve topikal antiglokomatöz ilaç kullanan hastaların dosyaları geriye dönük olarak incelendi. Çalışmaya 113 hastanın sağ gözü dahil edildi. Pnömotonometre ve tonopen ile elde edilen GİB değerleri GAT ile elde edilen GİB değerleri ile istatistiksel yöntemlerle karşılaştırıldı ve seriler arasındaki korelasyon araştırıldı.
Bulgular:52\'si erkek, 61\'i kadın (p = 0,638) 113 hastanın yaş ortalaması 57,41 ± 11,02 yıl (41 - 82 yıl) idi. Ortalama GİB değeri GAT ile 21,04 5,40 mmHg (12 - 46 mmHg), pnömotonometre ile 20,19 ± 5,61 mmHg (12 - 48 mmHg) ve tonopen ile 17,37 ± 4,99 mmHg (8 - 44 mmHg) idi. Gerek pnömotonometre gerek tonopen ile elde edilen ortalama GİB değerleri GAT ile elde edilen ortalama GİB değerinden anlamlı olarak düşüktü (her ikisi için de p <0,001). Hem pnömotonometre (r =0,96 ve p <0,001) hem de tonopen (r =0,83 ve p <0,001) ile elde edilen GİB ölçümleri, GAT ile elde edilen GİB ölçümleriyle anlamlı şekilde korele idi.
Sonuç:Primer açık açılı glokomu olan ve topikal antiglokomatöz ilaç kullananlarda pnömotonometre ve tonopen ile ölçülen GİB, GAT ile ölçülen değerlerden daha düşük ve bu değerlerle koreledir.
