Abstract

Evaluation of the thicknesses of medial and lateral rectus muscles with magnetic resonance imaging in patients with horizontal strabismus: the effect of amblyopia We aimed to investigate the effect of amblyopia on the thicknesses of medial and lateral rectus muscles in patients with concomitant horizontal strabismus. Thicknesses of medial and lateral muscles of 73 patients who had concomitant horizontal strabismus and were being followed by the Pediatric Ophthalmology and Strabismus Unit of Gülhane Military Medical Academy were measured on primary gaze position with magnetic resonance imaging with two-mm slice thickness on T1-weighted axial slices. Differences between the patients who had and who did not have amblyopia were evaluated statistically. The mean diameter of lateral rectus muscle in patients with amblyopia and esotropia (1.33±0.38 mm) was significantly thinner than the mean diameter of lateral rectus muscle in patients with esotropia and without amblyopia (2.05±0.74 mm) (p=0.007). The mean diameter of lateral rectus muscle in patients with amblyopia and exotropia (3.38+1.27 mm) was significantly thicker than the mean diameter of lateral rectus muscle in patients with exotropia and without amblyopia (1.91 ±0.8 mm) (p<0.001). There were no statistically significant differences between the mean diameters of medial rectus and tateral rectus muscles in patients with either esotropia or exotropia but without amblyopia. Prominent changes occur in horizontal rectus muscles in the presence of amblyopia in patients with horizontal concomitant strabismus.

Özet

Bu çalışmada, konkomitan horizontal kayması bulunan olgularda, ambliyopitinin iç rektus ve dış rektus kas kalınlıklarına etkisinin araştırılması amaçlanmıştır. GATA Pediatrik Oftalmoloji ve Şaşılık birimince takip edilen tümü erkek, konkomitan horizontal şaşılığı bulunan 73 olguda, primer bakış pozisyonunda, iç ve dış rektus kas kalınlıkları manyetik rezonans görüntüleme yardımıyla T1 aksiyal kesitlerde iki mm kesit kalınlığı kullanılarak ölçüldü. Ambliyopisi bulunan ve bulunmayan olgular arasındaki farklılıklar istatistiksel olarak değerlendirildi. Ambliyopi+ezotropya olgularındaki dış rektus kas kalınlığı ortalaması (1.33±0.38 mm), ambliyopisi olmayan ezotropya olgularının kas kalınlığı ortalamasından (2.05±0.74 mm) anlamlı şekilde inceydi (p=0.007). Ambliyopi+ekzotropya olgularının dış rektus kas kalınlığı ortalaması (3,38±1.27 mm), arnbliyopi bulunmayan ekzotropya olgularının dış rektus kalınlığına (1.91±0.8 mm) göre antamlı şekilde kalındı (p<0.001). Ambliyopi olmayan ezotropya ve ekzotropya olgularının iç rektus ve dış rektus kas kalınlıkları ortalamaları arasında anlamlı farklılık saptanmadı. Horizontal konkomitant şaşılık olgularında, ambliyopi varlığında horizontal rektus kaslarında belirgin değişiklikler oluşmaktadır.
