Summary
Diabetic patients with ocular ischemic syndrome (OIS) often show asymmetrical eye findings. Iris neovascularization in OIS indicates a poor visual prognosis, highlighting the need for early detection in diabetes.
Area of Science:
- Ophthalmology
- Diabetology
- Vascular Medicine
Background:
- Diabetes mellitus is a significant risk factor for carotid occlusive disease.
- Carotid occlusive disease can lead to ocular ischemic syndrome (OIS), affecting vision.
- Understanding OIS in diabetic patients is crucial for managing visual complications.
Purpose of the Study:
- To retrospectively analyze the ocular manifestations and visual prognosis of OIS in diabetic patients.
- To identify clinical features associated with different OIS presentations in this population.
Main Methods:
- Retrospective analysis of 23 diabetic patients diagnosed with OIS.
- Patients were categorized into two groups based on the presence or absence of iris neovascularization.
- Clinical features and visual outcomes were reviewed for each group.
Main Results:
- Patients without iris neovascularization showed varied visual loss, with some experiencing severe vision loss due to optic neuropathy.
- Eyes with iris neovascularization experienced severe visual deterioration, and treatments were largely unsuccessful.
- Asymmetrical ocular findings were noted in both groups, and carotid surgery showed some benefit in the non-neovascularization group.
Conclusions:
- Ocular ischemic syndrome in diabetic patients can mimic diabetic retinopathy with asymmetrical ocular signs.
- The presence of iris neovascularization is a strong predictor of poor visual prognosis in diabetic OIS.
- Early recognition of OIS in the context of diabetes mellitus is essential for timely intervention and management.
