Özet
ipsilateral orbita, optik kiazma ve karşı optik sinire yayılım gösteren olguyu sunmak. On yıl önce dış merkezde sol gözünün tümör nedeniyle alındığını belirten 51 yaşındaki erkek olgu sol göz kapaklarında şişlik ve ağrı flikayetiyle kliniğimize başlvurdu. Olgu oftalmolojik ve radyolojik olarak değerlendirildi. Sol göz kapakları ödemli ve hiperemik olan olgunun soket konjonktivasında hiperpigmente kitle saptandı. Sağ göz ön ve arka segmenti normal olup görme keskinli¤ i 10/10 idi. Orbita bilgisayarlı tomografide sol orbital boşluğun kitle ile dolu olduğu izlendi. Kitlenin intrakraniyal uzanımı olmadığu belirlendi. Sistemik metastaz saptanmayan olguya total ekzanterasyon uygulandı. Histopatolojik incelemede malign melanom izlendi. On ay sonra sağ gözde ani görme kaybı ile geldi. Sağ gözde ışık hissi yoktu. Gözdibi bakısında optik sinir başı soluktu. Görsel uyaranlı potansiyel tetkiki ile sağ gözden p100 dalgası elde edilemedi. Orbita bilgisayarlıtomografide optik kiazma ve sağ optik siniri tutan kitle belirlendi. Göz dışı yayılımı saptanmayan koroid malign melanomu do¤ru yöntemlerle tedavi edildi¤inde prognozu oldukça iyi bir tümördür. ‹ntraoküler tümör flüphesi olan olgularda enükleasyon yapılırken göz dışı yayılıma neden olabilecek gereksiz manevralardan kaçınmaya özen gösterilmelidir. Ekstraoküler yayılım mevcudiyetinde ekzanterasyon uygulanmalıdır. (Turk J Ophthalmol 2011; 41: 194-6)
To report a case of tumor invasion into the ipsilateral orbit/optic chiasm and into the contralateral optic nerve. A 51- year-old male who declared removal of his left eye ten years ago elsewhere, attended to our clinic for swelling of the left eyelids and pain. He was ophthalmologically and radiologically evaluated. A hyperpigmented mass was detected at the socket conjunctiva of the patient whose eyelids were swollen and hyperemic. Anterior and posterior segments of the right eye were normal, and the best corrected visual acuity was 10/10. On orbital computed tomography, the left orbit was found to be filled with mass. No intracranial invasion was detected. Exenteration was performed to the patient who had no systemic metastasis. Histopathological examination revealed malignant melanoma. Ten months later, the patient presented with sudden visual loss. Light perception was absent in the right eye. Optic nerve head was pale at fundus examination. No p100 wave was obtained from the right eye with visual evoked potentials. On orbital magnetic resonance imaging, a mass invading the optic chiasm and the right optic nerve was evident. When treated with appropriate methods, choroidal malignant melanoma with no extraocular extension has pretty good prognosis. When performing enucleation in patients with intraocular tumor suspicion, extra care should be spent not to make any unnecessary maneuver leading to extraocular spread. In the presence of extraocular dissemination, exenteration should be performed. (Turk J Ophthalmol 2011; 41: 194-6)
