Asteroid hyalosis

Asteroid hyalosis is a degenerative condition of the eye involving small white opacities in the vitreous humor. It is named for its resemblance to a star-filled sky when viewed through an ophthalmoscope. The condition is typically asymptomatic and is most commonly found in elderly individuals.

Etiology[edit | edit source]

The exact cause of asteroid hyalosis is unknown, but it is believed to be related to aging and degenerative changes in the vitreous humor. Some studies have suggested a possible association with systemic diseases such as diabetes and hypertension, but this has not been definitively proven.

Clinical Presentation[edit | edit source]

Patients with asteroid hyalosis typically do not have any symptoms. The condition is usually discovered incidentally during a routine eye examination. In some cases, the opacities may be dense enough to cause a slight decrease in visual acuity or disturbances in night vision.

Diagnosis[edit | edit source]

The diagnosis of asteroid hyalosis is made based on the characteristic appearance of the opacities in the vitreous humor on ophthalmoscopic examination. No specific laboratory tests or imaging studies are needed.

Treatment[edit | edit source]

No treatment is usually necessary for asteroid hyalosis, as the condition does not typically cause any symptoms or affect vision. In rare cases where the opacities are dense enough to significantly impair vision, a vitrectomy may be considered.

Prognosis[edit | edit source]

The prognosis for asteroid hyalosis is generally good. The condition does not typically progress or lead to any serious complications.
