    Diabetic retinopathy can lead to severe vision loss. Postmortem analysis revealed active proliferative lesions and complications from surgery, even after treatment.

    Area of Science:

    • Ophthalmology
    • Pathology
    • Diabetic Retinopathy

    Background:

    • Diabetic retinopathy is a leading cause of blindness.
    • Proliferative diabetic retinopathy (PDR) involves abnormal blood vessel growth.
    • Vitreous hemorrhage and tractional retinal detachment are severe complications.

    Observation:

    • Postmortem examination of eyes from a diabetic patient with PDR, vitreous hemorrhage, and tractional retinal detachment.
    • One eye underwent argon laser panretinal photocoagulation and vitrectomy surgery.
    • Clinical appearance of lesions was atrophic, but pathologic study showed them to be "active".

    Findings:

    • Vascular and nonvascular proliferative lesions were equally severe in both operated and non-operated eyes.
    • Sclerotomy wounds showed intraocular granulation tissue and granulomatous inflammation.

  • Inflammation was related to suture fragments and intraocular hemorrhage.

    • Implications:

    • Argon laser panretinal photocoagulation and vitrectomy may not fully resolve active proliferative lesions in diabetic retinopathy.
    • Surgical interventions can lead to intraocular complications.
    • Further research is needed to understand the long-term efficacy and potential complications of treatments for advanced diabetic retinopathy.
