    Diyabetik Optik Nöropatilerde Ayırıcı Tanılar: Diyabetik Papillopati, İskemik Optik Nöropati ve Optik Atrofi
    (2018) Yassa, Ertuğrul Tan; Bakbak, Berker
    Diyabetik retinopatinin yıkıcı etkileri iyi bilinmektedir. Diyabetes mellitus (DM), diyabetik retinopatiden daha nadir olarak optik sinir komplikasyonlarına yol açmaktadır. DM'nin yol açtığı damarsal değişiklikler non-arteritik iskemik optik nöropati ve diyabetik papillopati oluşumuna katkıda bulunduğu düşünülmektedir. Optik atrofi, özgül bir bulgu değildir ve birçok optik nöropatinin kronik fazında ortaya çıkabilir. Bu derlemede, bahsi geçen optik sinir hastalıklarının klinik özellikleri, güncel tanı ve tedavi yaklaşımları, DM varlığı dikkate alınarak gözden geçirilmiştir

    Toxic anterior segment syndrome: Is it possible to have corneal dysfunction without changes in corneal morphology
    (2018) Yassa, Ertuğrul Tan; Bakbak, Berker
    Toxic anterior segment syndrome (TASS) is a sterile postoperative infl ammatory reaction caused by a noninfectious substance thatenters the anterior segment, resulting in a wide range of toxic damage to intraocular tissues. The process typically begins 12 to 48 hoursafter anterior-segment surgery, but delayed mild cases have been reported. In this paper, a case of mild late-onset TASS that specifi callycaused corneal edema without changes in corneal morphology is described. While, ideally, corneal morphology should be documentedby a corneal confocal microscopy, this case could be documented by a biomicroscopic anterior and posterior segment examination,central corneal thickness (CCT) detection by a corneal B mode ultrasound and a corneal specular microscope without corneal confocalmicroscopy. For this case, mild corneal edema was observed on postoperative day 32 (the CCT was 701 ?m on postoperative day 32,602 ?m on postoperative day 75) without any specular microscopic changes (the preoperative endothelial cell density was 2660 cells/mm 2 , and on postoperative day 75, it was 2660 cells/mm 2 ) and major infl ammation in the anterior and posterior segment of the eye,which responded well and promptly to topical steroid treatment. The aim is to contribute to the identifi cation and proper management ofsimilar patients and to discuss whether TASS causes corneal dysfunction without changes in corneal morphology, as the early detectionof mild cases is important in preventing potentially severe cases.
