Dilated episcleral vessels and open-angle glaucoma.

R L Radius, A E Maumenee

    American Journal of Ophthalmology
    |July 1, 1978
    PubMed
    Summary

    Idiopathic dilated episcleral vessels may be linked to open-angle glaucoma. Three of four patients with this condition showed glaucoma, suggesting a potential association between vascular anomalies and intraocular pressure.

    Area of Science:

    • Ophthalmology
    • Vascular Biology

    Background:

    • Idiopathic dilated episcleral vessels are a rare finding.
    • The association between episcleral vascular anomalies and glaucoma is not well-established.

    Observation:

    • Four patients with idiopathic dilated episcleral vessels were studied.
    • Three patients presented with asymmetric or unilateral open-angle glaucoma in the eye exhibiting greater episcleral vascular anomaly.
    • One patient had dilated episcleral vessels without elevated intraocular pressure (IOP).

    Findings:

    • In patients with elevated IOP, decreased facility of outflow was observed.
    • Schlemm's canal was engorged with blood in one eye despite a high IOP (35 mm Hg).
    • The study explored the potential for a congenital vascular anomaly.

    Implications:

    • Dilated episcleral vessels may serve as a clinical sign for underlying glaucoma.
    • Further research is warranted to elucidate the pathophysiology linking episcleral vascular anomalies and glaucoma.
    • This finding could influence diagnostic approaches for certain glaucoma patients.
