Familial nanophthalmos.

H E Cross, F Yoder

    American Journal of Ophthalmology
    |March 1, 1976
    PubMed
    Summary
    This summary is machine-generated.

    This study identifies a unique form of microphthalmos in a family, suggesting a new autosomal-recessive genetic mutation. The condition affects eye development and retinal perfusion, with potential glaucoma risk.

    Area of Science:

    • Ophthalmology
    • Medical Genetics

    Background:

    • Microphthalmos is a congenital condition characterized by small eye size.
    • Genetic factors play a significant role in the etiology of various ocular developmental disorders.

    Observation:

    • Four individuals from a single sibship presented with microphthalmos.
    • Funduscopic examination revealed an irregular,
    • rippled
    • appearance of the fundi with alternating light and dark red coloration.

    Findings:

    • Fluorescein angiography demonstrated patchy choriocapillaris perfusion.
    • Unusually rapid diffusion of fluorescein into the retina was observed.
    • Genealogic and geographic data indicated a strong likelihood of autosomal-recessive inheritance.

  • Glaucoma developed in only one affected individual.

    • Implications:

    • The unique constellation of ocular abnormalities suggests a novel recessive mutation.
    • This finding may contribute to understanding the genetic basis of microphthalmos and related retinal vascular anomalies.
    • Further research into this specific mutation could offer insights into diagnostic and therapeutic strategies for similar conditions.
