Congenital conjunctivo-limbo-corneal choristoma associated with marginal keratopathy
1Bindura Hospital, Mashonaland Central, Zimbabwe.
Insights
This case study describes an infant's conjunctival choristoma, a rare eye growth. Treatment with topical corticosteroids resolved associated keratitis, suggesting potential links to maternal rubella antibodies.
Area of Science:
- Ophthalmology
- Pediatric Ophthalmology
- Developmental Biology
Background:
- Ocular choristomas are congenital tumors composed of tissue elements not normally found in the eye.
- Early detection and management are crucial for preserving vision in infants.
- Understanding the etiology of choristomas aids in diagnosis and treatment strategies.
Observation:
- A three-day-old African infant presented with a three-day history of a red, injected right eye.
- Examination revealed a conjunctivo-limbo-corneal choristoma with associated marginal keratitis.
- High maternal rubella antibody titers were detected during investigation.
Findings:
- The conjunctival choristoma and marginal keratitis in the infant showed a positive response to topical corticosteroid treatment.
- The case highlights a potential association between ocular choristomas and maternal rubella infection.
- Discussion covers choristoma epidemiology, classification, pathogenesis, and surgical indications.
Implications:
- This case suggests that embryological errors or in-utero infections, such as rubella, may contribute to ocular choristoma development.
- Prompt treatment with corticosteroids can effectively manage associated inflammatory conditions like keratitis.
- Further research into the role of prenatal infections in choristoma formation is warranted.
Abstract:
We report a case of a three day old African baby who presented with a three day history of injected right eye. Examination disclosed an injected conjunctivo-limbo-corneal choristoma with associated marginal keratitis. Investigation disclosed a high maternal titer of rubella antibodies. The marginal lesions responded well to topical corticosteroids. Clinical manifestations of ocular choristomas epidemiology, classification, pathogenesis and indications for surgical treatment are discussed. We assume that an embryological error was the cause for the development of the choristomatous lesion but we cannot exclude the possibility of occult rubella infection during the early stages of pregnancy.
