Evaluation of ocular parameters in newly diagnosed obsessive-compulsive disorder children with eye-rubbing compulsion

Abstract

Purpose: To determine the ocular structural changes in obsessive-compulsive disorder (OCD) children with eye-rubbing compulsion. Methods: Participants recruited at the child and adolescent psychiatry clinic were evaluated for the OCD diagnosis. All patients underwent imaging with Scheimpflug corneal topography (Sirius, CSO, Italy), Tomey EM-4000 specular microscopy (Nagoya, Japan), and Lenstar LS 900 (Haag-Streit AG, Switzerland) optical biometry. Results: Both naive OCD and healthy control groups consisted of 40 patients. Mean cylindric diopter, coma, and trefoil values were significantly higher in the right eyes of OCD children. (P =.043,.024, and.028, respectively). Besides, lens thickness, total ocular aberrations, and high ocular aberrations (P =.014,.040;.027,.038; and.020,.013, in right and left eyes, respectively) were bilaterally higher in OCD children. Conclusion: Eye rubbing and mechanical trauma were proposed as risk factors for ocular structural changes. Early evaluation of corneal topographic parameters such as CylD, coma, and trefoil aberrations in newly diagnosed OCD children might assist in preventing future corneal ectatic diseases.
