Abstract

Purpose : Ultrasound biomicroscopy (UBM) is a high frequency B-mode ultrasound which can image the anterior segment at high resolution. The objective of this study was to evaluate the anterior segment and to demonstrate the associated pathologies in eyes with corneal opacities. Methods : Twenty-seven eyes of 26 patients that presented to our clinic with corneal opacities were evaluated with UBM (Paradigm Medical Industries.Inc.. Salt Lake City. UT). The imaging was performed using 50 MHz transducer. at 80 dB/mm gain and 5 dB/mm time-gain. After imaging the central cornea. peripheral cornea was imaged perpendicular to the limbus. all over 360°. Results : The age of the patients were between 10 and 83 years (mean: 53± 20.4 year). 8 of them were female and 18 were male. Nine eyes had aphakic-pseudophakic bullous keratopathy. 6 eyes had graft rejection. 9 eyes had corneal vascular leukoma. and 3 eyes had corneal leukoma. The results of the UBM showed that 81.5% of the eyes had anterior segment pathology associated with corneal opacification. These include; peripheral anterior synechiae in 14 eyes. anterior synechiae in 9 eyes. shallow anterior chamber in 8 eyes. posterior synechiae in 4 eyes. lens opacities in 4 eyes. anterior chamber opacities in 2 eyes. cyclitic membrane in 2 eyes. corneal endothelial thickening in 1 eye. traumatic aniridia in1 eye. iridodialysis in1 eye and haptic dislocation of an anterior chamber lens to the ciliary body through an peripheral iridectomy in 1 eye. In 5 eyes (18.5%) the anterior segment were normal. Conclusion : UBM is a useful diagnostic method to examine the anterior segment and ciliary body and also in planning keratoplasty in corneal opacifications.

Özet

Amaç: Ultrason biyomikroskopi (UBM) ön segmentin yüksek rezolüsyonda görüntülenebilmesini sağlayan yüksek frekanslı B-mod ultrasondur. Bu çalışmanın amacı kornea opasitesi olan gözlerde ön segmentin UBM ile değerlendirilerek kornea opasitesine eşlik eden patolojilerin belirlenmesidir. Yöntem: Kliniğimize kornea opasitesi ile başvuran 26 olgunun 27 gözü UBM (Paradigm Medical Industries,Inc., Salt Lake City, UT) ile değerlendirildi. Tüm görüntülemeler 50 MHz transducer kullanılarak 80 dB/mm gain, 5 dB/mm time-gain ayarında yapıldı. Görüntülemeler ilk olarak santral korneadan yapıldı, bunu takiben periferik kornea 360 derece, limbusa dik olarak görüntülendi. Bulgular: Olguların yaşları 10 ile 83 yaş arasında değişmekte olup (ort: 53 ± 20.4 yıl), 8'i kadın, 18'i ise erkekti. Dokuz gözde afakik-psödofakik büllöz keratopati, 6 gözde grefon hastalığı, 9 gözde korneal vaskülarize lökom, 3 gözde ise korneal lökom mevcuttu. UBM ile yapılan inceleme sonucu olguların %81.5'inde kornea opasitesine eşlik eden ön segment patolojisi saptandı. Bu patolojiler arasında; 14 gözde periferik ön sinesi, 9 gözde ön sinesi, 8 gözde sığ ön kamara, 4 gözde arka sinesi, 4 gözde lens kesafeti, 2 gözde ön kamarada opasiteler, 2 gözde siklitik membran, 1 gözde kornea endotelinde kalınlaşma, 1 gözde travmatik aniridi, 1 gözde irido-dializ ve 1 gözde ön kamara lensinin haptiğinin periferik iridektomiden siliyer cisim bölgesine dislokasyonu saptandı. Beş gözde (%18.5) ön segment normal olarak değerlendirildi. Sonuç: UBM ön segmentin optik olarak izlenemediği kornea opasitelerinde ön segment ve siliyer cismin değerlendirilmesinde ve keratoplastinin planlanmasında yardımcı bir tanı yöntemidir.
