Summary
Cold-induced ocular vasospasm was studied in patients with vasospastic disease. Nifedipine treatment resolved vasospasm in two patients, suggesting a potential risk for normal tension glaucoma.
Area of Science:
- Ophthalmology
- Neurology
- Vascular Medicine
Context:
- Investigating ocular vasospasm in patients with primary vasospastic disease.
- Assessing the impact of cold provocation on visual fields.
Purpose:
- To evaluate the occurrence and characteristics of cold-induced ocular vasospasm.
- To determine the efficacy of Nifedipine in treating ocular vasospasm.
- To identify potential risk factors for normal tension glaucoma.
Summary:
- Eight patients with primary vasospastic disease underwent visual field testing (Statpac 24-2) using a HUMPHREY autoperimeter.
- Tests included baseline, post-cold water immersion (13°C), and post-Nifedipine (10 mg) administration.
- Ocular vasospasm, indicated by visual field defects, was observed. Two patients experienced vasospasm regression following Nifedipine treatment.
Impact:
- Identifies Nifedipine as a potential treatment for cold-induced ocular vasospasm.
- Suggests that patients with resolved ocular vasospasm may be at increased risk for developing normal tension glaucoma.
- Highlights the utility of visual field testing in diagnosing and managing vasospastic conditions affecting the eye.
