Roth's spot

Roth's spot

Roth's spot (pronounced: /rɔːθz spɒt/) is a medical term referring to retinal hemorrhages with white or pale centers. They are named after Moritz Roth, a Swiss physician who first described them in the late 19th century.

Etymology

The term "Roth's spot" is derived from the name of the Swiss physician Moritz Roth, who first described these spots in 1872. The term "spot" is used to describe the appearance of these lesions on the retina.

Definition

Roth's spots are retinal hemorrhages characterized by a white or pale center. They are often associated with systemic diseases such as endocarditis, leukemia, diabetes, hypertension, and HIV/AIDS. The white center is thought to be caused by either coagulated fibrin or a colony of infectious organisms.

Symptoms

Roth's spots themselves do not cause symptoms. However, the underlying conditions associated with Roth's spots can cause a variety of symptoms, including fever, fatigue, weight loss, and vision problems.

Diagnosis

Roth's spots are typically diagnosed during an eye examination. The doctor will use a special instrument called an ophthalmoscope to look at the back of the eye and check for any abnormalities.

Treatment

Treatment for Roth's spots involves addressing the underlying condition causing the spots. This may involve antibiotics for endocarditis, chemotherapy for leukemia, or antiretroviral therapy for HIV/AIDS.
