Abstract
Purpose: Evaluation of changes in anterior chamber parameters with the Pentacam rotating Scheimpflug and axial length measurements (Alx) by ultrasound in patients who use isotretinoin for the treatment of acne vulgaris.
Methods: Twenty-nine eyes of 29 patients (15 men, 14 women) were evaluated with the Pentacam before the treatment, and at the 3rd and 6th months of treatment. The axial length was evaluated by ultrasound biometry. The non-parametric paired t-test was used to compare pretreatment and 3rd and 6th month anterior chamber depth (ACD), anterior chamber volume (ACV), anterior chamber angle (ACA) width, central corneal thickness (CCT), lens thickness (LT), pupil size, axial length measurement (Alx) and mean keratometry values (K).
Results: The mean age of the patients was 21.82 ± 4.14 years. The differences between the pretreatment and 3rd and 6th month ACD, ACV, CCT, Alx, LT and mean K values were statistically significant (p < 0.05). The differences between the pretreatment and 3rd and 6th month pupil size measurements were not statistically significant (p > 0.05). The differences between the pretreatment and 3rd month ACA measurements were statistically significant (p > 0.05), but there was no statistically significant difference with 6th month values (p < 0.05).
Conclusions: Isotretinoin treatment causes statistically significant changes in most anterior segment parameters during treatment.
