Abstract

This study aims to present a glaucoma case with delayed diagnosis be- cause of myelinated retinal nerve fiber layer. On ophthalmological exami- nation of a 58-year-old female patient with noted decrease in vision, cor- rected visual acuities were 0.9 in the right eye and 0.4 in the left eye, and intraocular pressures were 24 and 23 mmHg, respectively. In a slit-lamp examination, grade 1 nuclear sclerosis was observed in both the eyes. The iridocorneal angles were Grade 3 in both the eyes. On dilated fundus ex- amination, the optical disc was bilaterally surrounded with myelinated nerve fibers, and the right one was larger than the left one. Cup/disc ratio was found to be 0.9 on the right and 0.5 on the left. On standardized Hum- phrey visual field test peripheral advanced deep, concentric visual field constriction and enlargement of the blind spot, which was prominent on the right side, were detected. Moreover, the patient was diagnosed with primary open-angle glaucoma. The appropriate medical treatment was initiated. In this study, we mentioned that myelinated nerve fibers can be associated with glaucoma. In patients with myelinated nerve fibers, the evaluation of the optical disk should be more detailed, and in these patients, visual field assessment should be more carefully performed.

Özet

Bu olgu sunumunda son yıllarda, sağ gözde görme azalması şikayeti artan, ancak bu yakınması miyelinli sinir lifine bağlanan, geç tanı almış bir glokom olgusunun sunumu amaçlanmıştır. Elli sekiz yaşındaki bayan hastanın yapı- lan oftalmolojik muayenesinde düzeltilmiş görme keskinliği sağ gözde 0,4; sol gözde 0,9 düzeyindeydi. Göz içi basıncı (GİB), sağ gözde 24 mmHg, sol gözde ise 23 mmHg olup santral kornea kalınlığı sırasıyla 532 ve 526 ?m idi. Biyomikroskopik ön segment muayenesi bilateral grade 1+ nükleer skleroz dışında normal sınırlarda olan hastanın iridokorneal açısı her 2 gözde evre 3 (Schaffer) idi. Dilatasyonlu fundus muayenesinde sağda daha geniş olmak üzere optik diski çevreleyen bilateral miyelinli sinir lifi mevcut olup, çukurluk/disk (c/d) oranı sağ gözde 0,9; sol gözde 0,5 idi. Standart 30-2 Humprey görme alanında sağda daha belirgin olmak üzere kör noktada ileri düzeyde genişleme ve periferik konsantrik daralma gözlendi. Bu bulgular ile hastaya primer açık açılı glokom teşhisi konularak, antiglokomatöz tedaviye başlandı. Miyelinli sinir lifleri ile glokomun birlikte görülebileceği, miyelinli sinir lifi bulunan hastalarda optik sinirin ve görme alanının daha ayrıntılı ve dikkatli değerlendirilmesi gerekmektedir.
