ABSTRACT
PURPOSE: To assess the impact of ocular trauma associated with obstetric forceps delivery on the corneal endothelium in children. METHODS: Five patients who attended the Hospital for Sick Children, Toronto, between 2013 and 2016 with a diagnosis of unilateral obstetrical forceps-related corneal injury were included. Clinical presentation, best-corrected visual acuity, corneal endothelial cell density (ECD, cells/mm), and measures of cellular morphology were obtained. RESULTS: The mean follow-up duration was 30 ± 10 months. Mean ECD in the affected eye at initial assessment was significantly lower than that of the fellow eye (2576 ± 733 vs. 3481 ± 288 cells/mm, P = 0.02). At final follow-up, mean ECD was 3293 ± 175 and 1907 ± 524 cells/mm in the normal and affected eyes, respectively (P = 0.004). The mean annual rate of the ECD decrease was higher in the affected eyes than in the normal eyes (9.1% ± 4.2% vs. 2.0% ± 2.5%), although this difference was not statistically significant (P = 0.06). CONCLUSIONS: In children with forceps-related corneal injury, lower ECD with a higher annual decrease can be assessed with specular microscopy for risk stratification and parental counseling purposes.
