Congenital glaucoma and retinal dysplasia

Area of Science:

• Ophthalmology
• Medical Genetics
• Pediatric Pathology

Background:

• Leukocoria (white pupil) in neonates necessitates a broad differential diagnosis, including retinal dysplasia, often associated with microphthalmia and chromosomal abnormalities.
• Congenital glaucoma and retinal dysplasia are typically distinct entities, rarely co-occurring.
• The potential impact of environmental factors, such as parental exposure to herbicides like Agent Orange, on congenital ocular malformations remains an area of investigation.

Observation:

• A neonate presented with leukocoria, enlarged eye, elevated intraocular pressure, and prominent iris vasculature.
• Family history revealed a paternal link to Agent Orange exposure and previous birth defects in another child.
• Ocular examination revealed posterior vitreous opacities, suggestive of an intraocular mass.

Findings:

• Histopathological examination confirmed retinal dysplasia, intraocular hemorrhage, and an anomalous corneoscleral angle.
• The corneoscleral angle demonstrated an anteriorly inserted iris with absence of the trabecular meshwork and Schlemm's canal.
• The unique combination of retinal dysplasia, congenital glaucoma, and a larger-than-normal eye was observed.

Implications:

• This case presents a unique clinical presentation of congenital ocular malformation, challenging existing diagnostic paradigms.
• The findings underscore the importance of considering a wide range of conditions in the differential diagnosis of neonatal leukocoria.
• Further investigation is warranted to explore the potential role of environmental exposures in the etiology of such complex ocular anomalies.
