Abstract

Persistent pupillary membrane (PPM) is a congenital ocular anomaly that typically manifests as fine strands of tissue across the pupil, remnants of a fetal vascular network. While most cases of PPM are benign and asymptomatic, rare instances can present with dense membranes that obstruct vision and lead to significant visual impairment. This report discusses the case of a 9-year-old male with unilateral dense PPM in the right eye, resulting in severe visual impairment. A thorough examination revealed normal corneal structure, but ultrasound B-scan showed a funnel-shaped retinal detachment. Given the retinal findings, surgical intervention for PPM was deemed inappropriate, and conservative management was chosen to minimize risks and preserve the patient’s remaining vision. This case highlights the importance of individualized management strategies in complex presentations of PPM, especially when associated with additional ocular pathologies.
