Summary
Ocular ischemic syndrome (OIS) often presents with severe vision loss and is linked to significant systemic vascular disease. Early diagnosis by ophthalmologists is critical for patient health, as OIS can indicate underlying cardiovascular and cerebrovascular conditions.
Area of Science:
- Ophthalmology
- Vascular Medicine
- Cardiology
Background:
- Ocular ischemic syndrome (OIS) is a severe condition characterized by reduced blood flow to the eye.
- It is often associated with systemic atherosclerosis and carries a poor visual prognosis.
Purpose of the Study:
- To investigate the clinical features of OIS.
- To determine factors influencing the development of OIS.
- To evaluate the management and outcomes of OIS patients.
Main Methods:
- Patient data collection included detailed medical and ocular histories.
- Ophthalmic evaluations involved fluorescein angiography.
- Carotid artery evaluation utilized duplex ultrasonography and/or aortic arch angiography.
Main Results:
- The study included 32 patients (39 eyes) with OIS, with a mean age of 68 years.
- Common findings included severe visual acuity reduction (64% ≤ 20/400), iris neovascularization (87%), and significant carotid artery stenosis (74%).
- Associated systemic diseases were prevalent, notably diabetes mellitus (56%), hypertension (50%), and coronary artery disease (38%).
Conclusions:
- Ocular ischemic syndrome has a poor visual prognosis.
- OIS diagnosis is crucial as it may be the initial manifestation of serious cerebrovascular and ischemic heart diseases.
- Prompt identification and management of underlying systemic conditions are vital.
