Ophthalmologic Presentations of Incontinentia Pigmenti

Area of Science:

• Ophthalmology
• Genetics
• Pediatrics

Background:

• Incontinentia pigmenti (IP) is a rare genetic disorder affecting the skin, nervous system, eyes, and skeleton.
• Ocular manifestations in IP, including retinal vascular abnormalities, can lead to significant vision loss if untreated.
• Early detection and intervention are crucial for managing the ophthalmic complications of IP.

Observation:

• A study included 18 patients (36 eyes) with incontinentia pigmenti, with a median age of 11 months at presentation.
• Retinal involvement was observed in 56% of the eyes, characterized by avascular areas.
• Widefield fundus photography and fluorescein angiography were used for ophthalmic examination and imaging.

Findings:

• Laser photocoagulation was the primary treatment for retinal manifestations, with 74% of treated eyes requiring only one session.
• No retinal detachment occurred in eyes treated with laser photocoagulation.
• Visual acuity remained stable or improved in 90% of eyes with recorded visual acuity at follow-up.

Implications:

• Laser photocoagulation is an effective treatment for preventing vision loss in patients with incontinentia pigmenti.
• Consistent ophthalmic monitoring and timely intervention can preserve visual function in children with IP.
• This study highlights the importance of a multidisciplinary approach to managing IP, involving ophthalmologists and geneticists.
