Asteroid Hyalosis: An Update on Prevalence, Risk Factors, Emerging Clinical Impact and Management Strategies

Area of Science:

• Ophthalmology
• Vitreoretinal diseases

Background:

• Asteroid hyalosis (AH) is characterized by refractile calcium and phospholipid deposits in the vitreous.
• First described in 1894, AH is noted for its

Purpose of the Study:

• To review the current literature on asteroid hyalosis (AH) epidemiology and pathophysiology.
• To provide updates on the clinical diagnosis and management of AH.

Main Methods:

• Literature review of epidemiological data.
• Analysis of suggested systemic and ocular risk factors.
• Summary of current diagnostic and management approaches.

Main Results:

• Global prevalence of AH is approximately 1%, with a strong association with older age.
• Pathophysiology remains unclear, but risk factors are being investigated.
• Clinical management focuses on differentiating AH from other conditions and managing visual impairment.

Conclusions:

• AH is a common, benign condition primarily affecting the elderly.
• Further research into pathophysiology may reveal underlying mechanisms.
• Current management emphasizes accurate diagnosis and retinal evaluation.
