Evaluation of Ocular Parameters in Newly Diagnosed Obsessive-Compulsive Disorder Children With Eye-Rubbing Compulsion.

This article investigates ocular structural changes in children newly diagnosed with obsessive-compulsive disorder (OCD) who exhibit eye-rubbing compulsions. Using Scheimpflug corneal topography, specular microscopy, and optical biometry, the study found that OCD children showed significantly higher cylindric diopter, coma, and trefoil aberrations in the right eye, as well as increased lens thickness and total and high ocular aberrations bilaterally, compared to healthy controls. The findings suggest that mechanical trauma from eye rubbing and associated inflammation may contribute to early corneal alterations, potentially increasing the risk for corneal ectatic diseases such as keratoconus. Early ophthalmologic evaluation of corneal topographic parameters in OCD children may aid in preventing progression of such ocular conditions.
