Abstract

Purpose: To examine the retinal nerve fiber layer (RNFL) thickness by using spectral domain optical coherence tomography (OCT) in newly diagnosed and treatment-naive multiple sclerosis (MS) patients without a history of optic neuritis. Material and Methods: This prospective study included the newly diagnosed 30 eyes of 15 MS patients and 30 eyes of 15 healthy individuals as the control. Peripapillary RNFL thickness was measured in each eye with spectral domain OCT as an average (3600) and by quadrants (superior, nasal, inferior and temporal). Mean RNFL values were compared with the control group. Statistical analysis was carried out using Student’s t test. Results: Mean average RNFL thickness was 86. 4±15.4 &#956;m in the MS group and 98.0±9.1 &#956;m in the control group (p<0.05). When evaluated by quadrants, the decrease in the RNFL was statistically significant in the temporal and inferior quadrants in the MS group (p<0.05). Conclusion: Spectral domain OCT is a useful, objective and safe tool that can detect axonal loss in newly diagnosed MS patients without optic neuritis. However, larger and controlled clinical studies with OCT are needed to detect the follow-up intervals and the starting time of neuroprotective treatment in subclinical patients.

Özet

Amaç: Yeni tanı konmuş ve optik nevrit geçirmemiş multiple skleroz (MS) hastalarında, spektral domain optik koherens tomografi (OKT) ile retina sinir lifi tabakası (RSLT) kalınlığının incelenmesi. Gereç ve Yöntem: Bu geriye dönük çalışmaya yeni tanı almış 15 MS hastasının 30 gözü ve kontrol grubu olarak 15 sağlıklı gönüllünün 30 gözü dahil edildi. Peripapiller RSLT kalınlıkları her göz için ortalama (3600) ve 4 kadrandan (superior, nazal, inferior ve temporal) olacak şekilde spektral domain OKT ile ölçüldü. Elde edilen RSLT değerleri kontrol grubununkilerle karşılaştırıldı. İstatistiksel analiz Student’s t testi ile yapıldı. Bulgular: Ortalama (3600) RSLT kalınlıgı MS grubunda 86.4±15.4 μm, kontrol grubunda 98.0±9.1 μm olarak ölçüldü (p<0.05). Tek tek kadranlar açısından değerlendirildiğinde MS grubunda RSLT’deki azalma, kontrol grubuyla karşılaştırıldığında, temporal ve inferior kadranda anlamlıydı (p<0.05). Sonuç: Spektral domain OKT, yeni tanı almış ve optik nevrit geçirmemiş multiple skleroz hastalarındaki akson kaybının saptanmasında kullanışlı, güvenilir ve objektif bir yöntemdir. Henüz tanı almamış subklinik hastalarda, OKT ile yapılacak geniş kapsamlı ve kontrollü çalışmalarla, hangi aralıklarla hastaların takip edilmesi gerektiği ve nöroprotektif tedaviye başlama zamanı belirlenmelidir.
