Medical Care
- General
- In a child suspected of having Peters anomaly, a thorough physical examination by a pediatrician is warranted.
- Genetic counseling must be offered as needed.
- Ocular
- Glaucoma is very common in patients with Peters anomaly, occurring in up to 90% of them. No Food and Drug Administration (FDA)-approved medications are available for the treatment of glaucoma in children.
- A pediatric glaucomatologist best manages these patients.
Surgical Care
- For patients with a clear peripheral cornea, peripheral optical iridectomy may be performed.
- For patients with bilateral visually disabling corneal opacity, penetrating keratoplasty is recommended. To prevent amblyopia, the earlier the surgery is performed (eg, before 3-6 mo), the better the results. The rates of graft clarity are between 20-60% in different studies.20,21,22,23,24,25,26
- For patients with cataract, lensectomy/vitrectomy is indicated. If left aphakic, these patients will require aphakic contact lenses or aphakic spectacles.
- Filtration surgery, cryoablation, or a tube shunt may be required for those patients with glaucoma whose increased intraocular pressure cannot be managed by medications.27
Consultations
- Pediatrician - Thorough examination to rule out other systemic abnormalities
- Geneticist - Genetic counseling
- Pediatric glaucomatologist - Management of glaucoma (Most patients with Peters anomaly have glaucoma. No FDA-approved glaucoma medications are available for children.)
- Vitreoretinal surgeon - Lensectomy/vitrectomy
- Cornea specialist - Keratoplasty
- Low-vision specialist - Management of poor vision, provision of optical aids
