Abstract
PURPOSE: To evaluate the aspects of OCT and visual field (VF) tests in the diagnosis and following up of patients with small uveal malign melanomas. MATERIAL AND METHODS: Routine opthalmological examinations were preceded by ultrasonography, magnetic resonance, fundus fluorescein and indocyanine green angiography, fundus photography, OCT, static and kinetic perimetry tests. RESULTS: Fortythree patients with initial dignosis of uveal melanoma attended to Istanbul University Cerrahpaşa Medical Faculty Ocular Oncology Section of Ophthalmology Department between January 1999 and December 2000. After further tests and controls 8 patients were excluded from the study since they were proved as to be non-melanoma masses 5 of which were related to senile macular degeneration. Our study consists of 35 cases 14 male and 21 female. Patient ages ranged from 32 to 79 with a median of 55. Among 20 cases which OCT and VF tests were both performed, 12 cases showed defective results in both OCT and VF tests, in 17 cases OCT were normal and VF defective, 1 patient's mass was off screen in OCT while VF was normal, in 3 cases OCT were defective while VF tests were normal. OCT results revealed various pictures like hyperreflectivity of retinal pigment epithelium (RPE) elevation or detachment of RPE layer and neurosensorial retina. In visual field tests sector defects and paracentral scotomas were noticeable. Sloping or steep edges and absolute or relative scotomas were insignificant. CONCLUSION: OCT and visual field tests are complimentary tests in diagnosis of small uveal melanomas.
Özet
AMAÇ: Koroid malign melanomlarının (KMM) ayırıcı tanısında Optik Koherens Tomografi (OCT) ve Görme Alanının (GA) teşhisteki rolünü araştırmak GEREÇ VE YÖNTEM: KMM'lerin tanısında melanom ön tanısıyla başvuran hastalara sistemik göz muayeneleri, ultrasonografi (USG), fundus floresein anjiyografi (FFA), indocyanine green anjiyografi (ICGA), manyetik rezonans (MR) muayeneleri yanında OCT ve GA muayeneleri yapılarak ayırıcı tanı sağlanmaya çalışıldı. BULGULAR: KMM ön tanısıyla başvuran 43 olgunun 35'inde tetkikler sonucu küçük KMM saptandı. OCT bulguları olarak retina pigment epiteli (RPE) kalınlaşmasına bağlı hiperreflektivite, RPE elevasyonu, RPE dekolmanı, retina dekolmanı (RD) ve subretinal kistik boşluklar dikkati çekti. GA muayenesinde parasantral rölatif skotom, parasantral absolü skotom, sektör defekti ve kör noktanın büyümesi tespit edildi. OCT ve GA beraber yapılabilen 20 olgunun 12'sinde hem OCT hem GA defektif, 17'sinde OCT normal ve GA defektif, 1 olgunun kitlesi OCT ekranına girmezken GA defektif, 2 olguda OCT ve GA normal, 1 olguda kitle OCT ekranına girmezken GA normal, 3 olguda ise OCT defektif GA normal bulundu. SONUÇ: KMM'ların tanısında OCT ve görme alanı birlikte değerlendirildiğinde lezyonun aktivitesi hakkında önemli veriler vereceği düşünülmektedir.
