BACKGROUND: Vitiligo is one of the common pigmentary disorders affecting the ocular structures.
AIM: To determine the retinal nerve fiber layer (RNFL), retinal pigment epithelium (RPE), and choroidal thickness (CT) in vitiligo patients and to evaluate the relationship between choroidal thickness and vitiligo subtypes.
METHODS: The right eyes of 106 participants (51 vitiligo, 55 nonvitiligo) were included in the study. All of the participants underwent detailed eye examinations and spectral-domain optical coherence tomography (SD-OCT) examinations. CT was measured manually with enhanced depth imaging optical coherence tomography (Edi-OCT) (subfoveal [SubF], nasal n500 µm [N1], n1500 µm [N2]), and temporal (t500 µm [T1], t1500 µm [T2]).
RESULTS: In vitiligo patients, CT values were significantly lower in the SubF, N1, N2, T1, and T2 areas compared to the control group (P = .001, P = .011, P = .002, P = .005, P ˂ .001, respectively). Periorbital involvement did not affect CT (P = .355, P = .746, P = .443, P = .633, P = .558, respectively). However, in patients with periorbital region involvement, the CT was significantly reduced if the lesion had a universal character (P ˂ .001, P = .001, P = .011, P ˂ .001, P = .002, respectively). It was observed that RPE thickness decreased in vitiligo, but this difference was not statistically significant (P = .140). RNFL thickness was unaffected in all quadrants. A positive correlation (r = .286, r = .280, respectively) was observed between the Vitiligo Area Severity Index (VASI) and age and disease duration. A negative correlation (r = -.360, r = -.316, r = -.315, r = -.313, respectively) was found in the CT of the SubF, N1, N2, T1, and T2 areas.
CONCLUSION: Vitiligo patients should be closely monitored for possible posterior ocular segment disorders.
