PRİMER AÇIK AÇILI GLOKOMLU HASTALARDA GÖZ ELASTİSİTESİ

Amaç: Bu çalışmada primer açık açılı glokom PAAG hastalarının oküler ve perioküler yapılarının elastisite değişikliklerinin sonoelastografi ile değerlendirilmesi amaçlandı. Hastalar ve Yöntem: PAAG’li 43 hasta 19 erkek, 24 kadın; 45-80 arası, ortalama yaş, 63.20 ± 2.31 yıl prospektif olarak incelendi. Bu hasta grubu refraksiyon kusuru dışında göz hastalığı olmayan 28 birey 17 erkek, 11 kadın, 40-85 yaş arası, ortalama yaş, 63.50 ± 1.89 yıl kontrol grubu ile karşılaştırıldı. Oftalmolojik değerlendirme ve B-mod ultrasonografi sonrasında, tüm katılımcılara semikuantatif sonoelastografik analiz yapıldı. Retrobulber yağ dokusu, optik sinir, lens ve retina-koroid-sklera kompleksinin RKSK elastikliği iki grup arasında sonoelastografi ile karşılaştırıldı. Student t-test ve Mann–Whitney U testi istatistik değerlendirme için kullanıldı. Bulgular: PAAG’li hastalar ve kontrol grubu arasında ölçülen perioküler ve oküler parametrelerde ortalama strain oranı belirgin farklılık göstermemektedir. Sonuç: Elastisite oranları perioküler ve oküler yapılarda PAAG ve PAAG olmayan hastalar arasında farklılık göstermemektedir.

Eye Elasticity In Patients With Primary Open Angle Glaucoma

Purpose: The present study was performed to assess elasticity changes in the ocular and periocular structures of patients with primary open angle glaucoma POAG via sonoelastography. Patients and Methods: Forty-three patients 19 male, 24 female; ranging from 45 to 80, mean age, 63.20 ± 2.31 years diagnosed with POAG were prospectively analyzed. This patient group was compared with a control group of 28 individuals 17 male, 11 female; ranging from 40 to 85, mean age, 63.50 ± 1.89 years who had no eye diseases apart from refractive errors. Following an ophthalmologic assessment and B-mode sonography, all participants underwent semiquantitative sonoelastographic analysis. The elasticity of the retrobulbar fat tissue, optic nerve, lens, and retina–choroid–sclera complex RCSC was compared between the two groups via sonoelastography. Student’s t test and the Mann–Whitney U test were used for statistical assessment. Results: There was no significant differences in the degree of elasticity of the ocular and periocular structures between patients with and without POAG. Conclusion: No difference was detected between elasticity levels of ocular and periocular structures in between patients with and without POAG.
