Summary
Optic disc drusen, a condition affecting 0.3% of the population, remain poorly understood. This review covers their history, epidemiology, clinical features, and diagnostic methods like ultrasonography and fluorescein angiography.
Area of Science:
- Ophthalmology
- Optic Neuropathy
Background:
- Optic disc drusen have been recognized for over a century.
- Their etiology and clinical associations are not fully understood.
- Observed in 0.3% of the population, with autopsy suggesting 2% incidence.
Purpose of the Study:
- To review the historical and epidemiological aspects of optic disc drusen.
- To detail the clinical and histological features of optic disc drusen.
- To discuss specialized diagnostic techniques for optic disc drusen.
Main Methods:
- Literature review of historical and epidemiological data.
- Analysis of clinical and histological findings.
- Discussion of diagnostic imaging techniques including ultrasonography and fluorescein angiography.
Main Results:
- Optic disc drusen are often asymptomatic, but can cause decreased vision and visual field deficits.
- Prevalence estimates vary between clinical observation and autopsy studies.
- Diagnostic techniques provide detailed structural and functional information.
Conclusions:
- Further research is needed to elucidate the etiology of optic disc drusen.
- Understanding clinical and diagnostic features is crucial for patient management.
- Specialized imaging aids in the diagnosis and monitoring of optic disc drusen.
