Iris neovascular tufts.

G Mason

    Annals of Ophthalmology
    |April 1, 1980

    Summary
    This summary is machine-generated.

    Bilateral iris neovascular tufts in an elderly patient with retinal branch vein occlusion suggested an underlying disorder. Further tests revealed abnormal insulin secretion, indicating a potential link between iris neovascularization and diabetes.

    Area of Science:

    • Ophthalmology
    • Endocrinology
    • Vascular Biology

    Background:

    • Iris neovascular tufts are capillary outgrowths from pupillary margins.
    • Previously reported in elderly, diabetic, and myotonic dystrophy patients, and with retinal vein occlusion.
    • The etiology of iris neovascular tufts can be multifactorial.

    Observation:

    • A case of unilateral acute retinal branch vein occlusion presented with bilateral iris neovascular tufts.
    • The patient was elderly and had a history of hypertension.
    • Despite a normal glucose tolerance test, an insulin tolerance test indicated diabetes.

    Findings:

    • The bilateral presentation of iris neovascular tufts suggested a systemic underlying condition.
    • Iris neovascularization appeared to correlate with abnormal insulin secretion.

  • The co-occurrence with branch vein occlusion might be coincidental.

    • Implications:

    • This case highlights a potential association between iris neovascular tufts and subclinical diabetes or abnormal insulin secretion.
    • Further research is warranted to explore the relationship between iris neovascularization and metabolic disorders.
    • Ophthalmologists should consider systemic evaluation in elderly patients presenting with bilateral iris neovascular tufts.
