Ocular findings in Kenny's syndrome
Archives of Ophthalmology (Chicago, Ill. : 1960)
|May 1, 1979
Summary
Kenny's syndrome is a rare congenital disorder characterized by dwarfism and hypocalcemia. Ocular findings are diverse, and ophthalmologists should screen for electrolyte abnormalities.
Area of Science:
- Ophthalmology
- Genetics
- Endocrinology
Background:
- Kenny's syndrome, first described in 1966, is a rare congenital disorder.
- It is characterized by dwarfism, thickened long bone cortex, transient hypocalcemia, and normal intelligence.
Observation:
- Ocular findings in affected individuals are varied, including nanophthalmos, hyperopia, pseudopapilledema, vascular tortuosity, and macular crowding.
- Postmortem examination revealed unique corneal calcium deposits and retinal calcification, distinct from band keratopathy.
- A pseudodoubling of the optic papilla was observed, prompting a review of optic nerve anomalies.
Findings:
- The study identified diverse ocular manifestations in Kenny's syndrome.
- Unique patterns of calcium deposition were noted in the cornea and retina.
- No confirmed cases of true optic nerve doubling were found in the literature review.
Implications:
- Ophthalmologists should consider Kenny's syndrome in patients presenting with unexplained ocular abnormalities and electrolyte imbalances.
- Early identification of hypocalcemia is crucial for managing patients with this syndrome.
- Further research into the genetic and molecular basis of Kenny's syndrome may elucidate its pathogenesis and lead to improved diagnostic and therapeutic strategies.
