Nöro-Oftalmolojik Hastalıklarda Optik Koherens Tomografisi

Optik Koherens Tomografisi OKT klinisyenlere optik sinir hastalıklarına yaklaşımda önemli bilgiler veren retina sinir lifi tabakası RSLT kalınlığını kantitatif olarak ölçme olanağı tanır. OKT cihazları artan tarama hızları sonucu gelişerek retina katlarının görüntülemesinde olağanüstü bir ayrıntıya ve hassasiyete ulaşılmıştır. OKT günümüzde çeşitli nöro-oftalmik durumlarda kullanılmaya başlanmıştır. Bunların arasında anterior iskemik optik nöropati AİON , toksik ve inflamatuar diğer optik nöropatiler, multiple sklerozis, nöromyelitis optika, psödotumor serebri, migren, optic sinir başı druseni, Leber’in herediter optik nöropatisi LHON , Alzheimer hastalığı ve Friedrich hastalığı yer almaktadır. Bu derlemenin amacı nöro-oftalmolojik hastalıklarda OKT kullanımı ile ilgili varolan yayınların gözden geçirilmesi ve klinik uygulamada kullanımını artırmaktır. OKT’nin optik sinir ve görme sistemi hastalıklarının değerlendirilmesinde yaygın kullanımı, nöro-oftalmolojik hastalıklardaki yargılarımızı, yaklaşımımızı, araştırmalarımızı ve anlayışımızı kökten değiştirmektedir

Optical Coherence Tomography In Neuro-Ophthalmological Diseases

Optical coherence tomography OCT provides clinicians with the ability to quantify the thickness of the retinal nerve fiber layer RNFL , which is useful in managing diseases of the optic nerve. OCT’s advancement refined its ability to image the retinal layers with incredible sensitivity by increasing scanner speed. OCT has been studied in several neuro-ophthalmic conditions, including anterior ischemic optic neuropathy, other toxic and inflamatuar optic neuropathies, multiple sclerosis, neuromyelitis optica, pseudotumor cerebri, migraine,optic nerve head drusen, compressive optic neuropathy, Leber’s hereditary optic neuropathy LHON , Alzheimer’s disease and Friedrich’s disease. The purpose of this review is to coalesce the current literature on the use of OCT in neuro-ophthalmology to enhance its use in clinical practice. OCT’s wide use in evaluating the optic nerve and the visual system has revolutionized our assessment, management, research, and understanding of neuro-ophthalmic diseases
