Late hyphema due to wound vascularization.

K C Swan

    Transactions. Section on Ophthalmology. American Academy of Ophthalmology and Otolaryngology

    Summary

    Deep vascularization at cataract surgery sites can cause delayed hyphema (bleeding) years later. This condition, stemming from vessel ingrowth, presents with blurred vision and is often diagnosed via gonioscopy.

    Area of Science:

    • Ophthalmology
    • Surgical Complications
    • Vascular Biology

    Background:

    • Delayed hyphema can occur months or years after cataract surgery.
    • This complication arises from abnormal vascularization at the surgical incision site.
    • Episcleral vessels may grow into the stromal wound, forming capillaries.

    Purpose of the Study:

    • To describe the phenomenon of delayed hyphema following cataract surgery.
    • To elucidate the underlying mechanism of vascular ingrowth leading to hyphema.
    • To outline the clinical presentation and diagnostic findings associated with this complication.

    Main Methods:

    • Review of clinical cases presenting with delayed hyphema post-cataract surgery.
    • Ophthalmoscopic and gonioscopic examination to identify vascular abnormalities.
    • Correlation of symptoms with surgical history and findings.

    Main Results:

    • Focal deep vascularization of the stromal wound was identified as the cause of delayed hyphema.
    • Symptoms include spontaneous or trauma-induced blurred vision.
    • Gonioscopy frequently reveals a small clump of vessels or the bleeding site.

    Conclusions:

    • Delayed hyphema after cataract surgery is linked to deep stromal wound vascularization.
    • Early identification via gonioscopy is crucial for diagnosis and management.
    • Understanding this vascular complication aids in patient counseling and follow-up care.
