A patient with bilateral persistent pupillary membrane: a conservative approach

Area of Science:

• Ophthalmology
• Pediatric Ophthalmology
• Visual Development

Background:

• Persistent pupillary membranes (PPMs) are congenital remnants of the pupillary membrane, typically found in children.
• Bilateral PPMs can potentially impact visual development and lead to conditions like amblyopia.
• Management strategies for PPMs range from conservative observation to surgical or laser interventions.

Observation:

• A case study of a 10-year-old girl with bilateral persistent pupillary membranes since childhood.
• The patient presented with ametropic amblyopia, a condition of reduced vision without a clear structural cause.
• Initial visual acuity and ocular health were otherwise normal, with no significant extraocular abnormalities.

Findings:

• The patient's ametropic amblyopia was successfully treated with spectacles and part-time occlusion therapy.
• Post-treatment, best-corrected visual acuity improved to 20/25 in both eyes.
• Stereopsis, ocular alignment (orthophoria), and extraocular movements were within normal limits after treatment.

Implications:

• Conservative management, including refractive correction and occlusion therapy, may be sufficient for bilateral PPMs.
• Surgical or laser interventions might not be necessary for all cases of PPMs, even when seemingly indicated.
• This case suggests a trial of non-invasive therapies before considering more aggressive treatments for PPM-related visual impairments.
