Amaç: Retina sinir lifi tabakası (RSLT) kalınlığı multipl sklerozlu (MS) hastalarda hastalık aktivitesinin izlenmesinde kullanılmaktadır. Retinanın maküler ganglion hücre kompleksi (GHK) tabakası da optik koherens tomografi (OKT) ile değerlendirilebilir ve MS’te potansiyel bir biyobelirteç olarak önerilmiştir. Bu çalışmada, maküler GHK ve bunun Multipl Skleroz (MS) hastalarında potansiyel bir biyobelirteç olarak rolünü araştırdık. Metod: Bu prospektif kohort çalışmasında, katılımcılar tekrarlayıcı (relapsing-remitting) MS hastalarından (n=62) ve sağlıklı kontrollerden (n=60) oluşuyordu. MS hastalarının gözleri optik nörit öyküsüne (ON) göre iki alt gruba ayrıldı. Spektral domain OKT ile standart peripapiller- RSLT, maküler tarama protokolü ve retinal oto-segmentasyonu gerçekleştirildi. Maküler RSLT (mRSLT), ganglion hücre tabakası (GHT) ve iç pleksiform tabaka (İPT) ile bu üç tabakanın toplamı olan GHK kaydedildi. Makula ETDRS halka sistemi kullanılarak dokuz sektöre bölündü (4×9=36 değişken). Bulgular: Toplamda 36 hastanın 50 gözünde geçirilmiş ON atağı saptandı. 36 GHK parametresinden 35’i, MS hastalarında ve alt gruplarda, kontrol grubuna göre daha inceydi (p<0.05). Optik nörit öyküsü olan ve olmayan gözler karşılaştırıldığında, 36 parametrenin 25’i, ON geçirenlerde daha inceydi. ON hikâyesi olan hastalarda görme keskinliği ve GHK parametreleri ile EDSS skorları arasında güçlü düzeyde korelasyonlar saptandı. Bununla beraber, ON hikâyesi olmayanlarda böyle bir ilişki bulunamadı. Sonuç: GHK, MS’de GHT, İPT ve mRSLT sırasıyla incelmektedir. GHK’nin ayrıntılı olarak incelenmesi MS için faydalı bir biyobelirteç olabilir.
Multiple sclerosis; ganglion cell complex; ganglion cell layer; inner plexiform layer; retinal nerve fiber layer
Introduction: Retinal nerve fiber layer thickness has been used for monitoring of disease activity in patients with multiple sclerosis (MS). Macular ganglion cell complex (GCC) layer of retina also can be measured by OCT and has been suggested as a potential biomarker in MS. In this study we investigated the macular GCC and its role as a potential biomarker in patients with Multiple Sclerosis (MS).Methods: A prospective cohort-study, subjects consisted of Relapsing- Remitting MS patients (n=62) and healthy controls (n=60). Eyes of MS patients were divided into two subgroups according to the history of the optic neuritis (ON). Standard peripapillary-RNFL and macular scan protocol, and retinal auto-segmentation of spectral-domain OCT were performed. Macular RNFL (mRNFL), ganglion cell layer (GCL), and inner plexiform layer (IPL), and GCC (the sum of these former three layers) were recorded. The macula was divided into nine sectors using the ETDRS grid (4×9=36 variables). Results: In total, 50 eyes of 36 patients had previous ON attacks. 35/36 GCC parameters were thinner in MS patients and subgroups compared to the control group (p<0.05). When the eyes with and without a history of optic neuritis were compared, 25 of 36 parameters were thinner in those with ON. There were strong correlations between visual acuity- GCC parameters and EDSS scores in patients with a history of optic neuritis. However, no such relationship was found in those without an ON story. Conclusion: Ganglion cell complex gets thinner in patients with MS with a decreasing order of GCL, IPL, and mRNFL. The examination of GCC in detail could be a beneficial biomarker for MS.
