Abstract
This study aimed to analyze the changes in meibomian glands (MGs) and tear film layer over time in patients taking systemic isotretinoin treatment. Patients who received systemic isotretinoin treatment between 4 and 8 months were prospectively followed up. In addition to full ophthalmologic examination, MG dysfunction (MGD), noncontact meibography, noninvasive and invasive tear break-up time (TBUT), ocular surface disease index (OSDI), corneal staining, and eyelid margin abnormality scores were recorded before, during, and after treatment. A total of 88 eyes of 88 patients were included in the study. The right eyes of all the patients were included. The mean age of the patients was 21 ± 2.9 years. Of the 88 patients, 70 (79.6%) were females and 18 (20.4%) were males. Before the treatment, MGD, noncontact meibography, first noninvasive TBUT, mean noninvasive TBUT, invasive TBUT, OSDI, corneal staining, and eyelid margin abnormality scores were 0.29 ± 0.45, 4.93 ± 3.50, 13.78 ± 3.89 s, 14.47 ± 3.09 s, 12.96 ± 3.61 s, 0.54 ± 1.00, 0.04 ± 0.20, and 0.09 ± 0.28, respectively. Twelve months after the end of treatment, the scores were 0.97 ± 0.87 (p < 0.001), 9.62 ± 3.89 (p < 0.001), 11.24 ± 3.52 s (p < 0.001), 12.34 ± 3.02 s (p < 0.001), 11.31 ± 2.90 s (p < 0.001), 1.90 ± 2.44 (p < 0.001), 0.20 ± 0.40 (p < 0.001), and 0.56 ± 0.49 (p < 0.001), respectively. Systemic isotretinoin treatment causes morphological changes in the MGs. However, this treatment may negatively affect the tear film layer of patients. Some of these changes may persist for a long time even if the treatment is discontinued.
