[Irvine-Gass syndrome. Statistical and angiographic study]

Area of Science:

• Ophthalmology
• Medical Research

Context:

• Investigated 12 cases of Irvine-Gass syndrome in 350 cataract surgery patients.
• Identified risk factors including male gender, hypertension, nuclear cataracts, and cryo-extraction.
• Observed increased incidence with vitreous bulge into the anterior chamber or vitreous incarceration in the surgical wound.

Purpose:

• To analyze the incidence and contributing factors of Irvine-Gass syndrome post-cataract surgery.
• To evaluate the relationship between syndrome onset and visual acuity restoration.
• To assess the role of the chorio-capillaris layer using fluorescein angiography.

Summary:

• Males were more affected than females.
• Arterial hypertension and nuclear cataracts increased disease frequency.
• Vitreous bulge and incarceration in the surgical wound were associated with higher incidence.
• Edema resolved faster if the syndrome appeared before cataract surgery, but visual acuity restoration was independent of timing.
• Fluorescein angiography revealed potential chorio-capillaris involvement and demonstrated its superiority over other imaging methods.

Impact:

• Highlights key risk factors for Irvine-Gass syndrome, aiding in surgical planning and patient selection.
• Demonstrates the diagnostic superiority of fluorescein angiography for assessing damage extent.
• Provides insights into the pathomechanisms and clinical course of Irvine-Gass syndrome.
