- Abstract
Objective: To evaluate the thickness of lamina cribrosa (LC) in patients with multiple sclerosis (MS) using optical coherence tomography (OCT) and the effect of optic neuritis (ON) attack on these measurements during the remission period. Methods: The study included 20 cases diagnosed with relapsing-remitting MS with a history of ON attacks affecting one eye and in remission of MS and ON attacks for at least three months, and 28 randomly selected eyes of age- and sex-matched healthy controls. In the MS group, the eyes affected by ON attack were assigned as Group 1 (MS+ON), their fellow unaffected eyes as Group 2 (MS-ON), and healthy control eyes as Group 3. The LC, peripapillary retinal nerve fiber layer (ppRNFL), and subfoveal choroidal thickness measurements were made by using OCT in all cases, and results were compared between the groups. Results: The mean LC thickness in MS+ON and MS-ON groups was significantly lower than the control group (p<0.001). There was no significant difference between MS+ON and MS-ON groups in terms of mean LC thickness (p=0.073). The mean ppRNFL in the MS+ON and MS-ON groups was statistically significantly lower than the control group (p=0.003, p=0.035, respectively). Conclusions: It is noteworthy that LC is significantly affected in eyes with MS who have not had a history of ON attack. Evaluation of the LC measurements can be important for early detection of optic nerve damage in patients with MS.
