[Eye symptoms in connatal lymphedema]

Area of Science:

• Ophthalmology
• Genetics
• Pediatrics

Background:

• Congenital lymphedema is a rare condition affecting lymphatic system development.
• Ophthalmic involvement in lymphedema can manifest in various ways, impacting ocular structures.

Observation:

• Two brothers presented with symptoms of congenital ophthalmic lymphedema.
• Clinical features included generalized lymphedema, antimongoloid eyelid, the 'cow-eye phenomenon', euryblepharon, and conjunctival lymphedema.
• The parents of the affected brothers were healthy, suggesting a non-dominant inheritance pattern.

Findings:

• The observed constellation of symptoms in siblings suggests a distinct genetic syndrome.
• The pattern of inheritance, with affected siblings and unaffected parents, strongly indicates recessive heredity.
• This case series points to a novel syndromic entity involving congenital lymphedema and specific ocular abnormalities.

Implications:

• Identification of this new syndrome expands the understanding of congenital lymphedema disorders.
• Recognition of recessive inheritance is crucial for genetic counseling and family planning.
• Further research is warranted to elucidate the specific genetic basis and molecular mechanisms underlying this condition.
