Elschnig Spots
Elschnig spots (pronunciation: /ˈɛlʃnɪg/; etymology: Named after Anton Elschnig, an Austrian ophthalmologist) are small, yellow or white, round areas of retinal pigment epithelium atrophy surrounded by a ring of hyperpigmentation. They are typically seen in hypertensive retinopathy, a condition that affects the retina's blood vessels due to high blood pressure.
Causes
Elschnig spots are caused by hypertensive retinopathy, a condition that affects the retina's blood vessels due to high blood pressure. They are a result of choroidal infarcts, which are areas of dead tissue due to a lack of blood flow.
Symptoms
The presence of Elschnig spots does not cause any symptoms. They are usually discovered during a routine eye examination.
Diagnosis
Elschnig spots are diagnosed through a fundus examination, a procedure that involves examining the interior surface of the eye, including the retina, optic disc, and macula.
Treatment
There is no specific treatment for Elschnig spots. The underlying cause, which is usually high blood pressure, should be treated to prevent further damage to the retina.
