Increased intraocular pressure following endarterectomy
Annals of Ophthalmology
|August 1, 1987
Summary
Neovascularization of the iris caused by carotid artery disease can regress with panretinal photocoagulation. However, carotid endarterectomy may increase intraocular pressure, potentially requiring surgery.
Area of Science:
- Ophthalmology
- Vascular Surgery
- Cardiology
Background:
- Neovascularization of the iris (NVI) can result from ocular ischemia due to carotid artery disease.
- Reduced carotid artery blood flow can lead to retinal and iris neovascularization.
Observation:
- Two patients with NVI secondary to carotid artery hypoperfusion were treated.
- Panretinal photocoagulation (PRP) was administered to both patients.
Findings:
- PRP led to regression of iris neovascularization in both patients, with varying degrees of response.
- Carotid endarterectomy in these patients resulted in increased intraocular pressure (IOP).
- One patient required filtering surgery to manage the elevated IOP post-procedure.
Implications:
- The study discusses potential mechanisms for IOP elevation after carotid endarterectomy.
- Understanding these mechanisms is crucial for managing patients with carotid artery disease and ocular complications.
- This highlights the complex interplay between carotid blood flow, ocular neovascularization, and intraocular pressure.
