Anterior segment ischemia in Fuchs' heterochromic cyclitis

Area of Science:

• Ophthalmology
• Vascular Biology

Background:

• Fuchs' heterochromic cyclitis (FHC) is an uncommon chronic ocular inflammation.
• Understanding the vascular aspects of FHC is crucial for managing potential complications.

Observation:

• Anterior segment 10% fluorescein sodium angiography was performed on six patients with early FHC.
• The study focused on visualizing iris vasculature and anterior segment perfusion.

Findings:

• All patients exhibited anterior segment perfusion defects.
• Leakage from iris vasculature was consistently observed.
• These findings suggest chronic anterior segment ischemia in early FHC.

Implications:

• Chronic anterior segment ischemia may be a key factor in FHC pathogenesis.
• This ischemia could predispose eyes to complications like rubeosis and neovascular glaucoma.
• Further research into vascular changes in FHC is warranted.
