Abstract:
Forty-four unselected patients with amaurosis fugax (AF) have been followed for 4.6 years (mean 2.6). Thirty per cent had atheromatous lesions, 20% had miscellaneous diagnoses (temporal arteritis 5, transitory ocular hypertension 2, glaucomatous iritis 1, benign intracraniel hypertension 1), 50% consisted of young, mainly women, in whom no cause was found. Prior to AF 2 had hemiplegia, 4 TCI, one optic atrophy and suspicion in 3. None died, one developed hemiparesis and one macular degeneration. An individual conservative attitude to AF seems justified in this material.
Insights
Amaurosis fugax (AF) affects young women often without a clear cause. This study suggests a conservative approach is appropriate for managing transient vision loss, as severe outcomes were rare in the observed cohort.
Area of Science:
- Ophthalmology
- Neurology
- Vascular Medicine
Background:
- Amaurosis fugax (AF) is a transient episode of vision loss.
- Etiology of AF can range from atheromatous disease to idiopathic causes, particularly in younger patients.
Purpose of the Study:
- To evaluate the long-term outcomes of patients diagnosed with amaurosis fugax.
- To determine the appropriate management strategy for AF based on patient outcomes.
Main Methods:
- A cohort of 44 unselected patients with AF was followed prospectively.
- Data collected included underlying causes, prior neurological events, and subsequent visual or systemic complications.
Main Results:
- Fifty percent of patients were young females with an undetermined cause for AF.
- Atheromatous lesions were present in 30%, and 20% had other miscellaneous diagnoses.
- No deaths occurred; one patient developed hemiparesis and one macular degeneration during the follow-up period.
Conclusions:
- A significant proportion of AF cases, especially in young women, remain idiopathic.
- The low incidence of severe complications supports a conservative management approach for amaurosis fugax.
