Congenital pterygium with anterior segment dysgenesis: rare ocular manifestation in Rubinstein-Taybi syndrome.
Case Report
Pterygium is a benign, wing-shaped fibrovascular overgrowth of subconjunctival tissue that can encroach over the cornea. This condition usually occurs in individuals aged 20-40 years but is rarely seen in children. We report a case of an infant with Rubenstein-Taybi syndrome presenting with nebulo-macular corneal opacity and congenital pterygium. On examination under anaesthesia, bilateral infero-nasal nebulo-macular corneal opacity (6 × 5 mm) with a whitish pink tissue originating from nasal bulbar conjunctiva was noticed. The probe test was negative for this tissue. To the best of our knowledge, only two other cases of congenital pterygium have been reported in the literature. The presence of this anomaly supports the hypothesis of genetic factors having a role in the development of pterygium.
