White dot syndromes
White dot syndromes
White dot syndromes (/waɪt dɒt ˈsɪndroʊmz/) are a group of rare inflammatory diseases that affect the retina and choroid of the eye. The term "white dot syndromes" is derived from the appearance of white dots that are seen in the back of the eye. These syndromes are often characterized by inflammation and damage to the retina, choroid, or both.
Etymology
The term "white dot syndromes" is descriptive, referring to the appearance of white dots in the back of the eye during an examination. The word "syndrome" is derived from the Greek "σύνδρομον" (sýndromon), meaning "concurrence of symptoms" or "concurrence of signs".
Types of White Dot Syndromes
There are several types of white dot syndromes, including:
- Acute posterior multifocal placoid pigment epitheliopathy (APMPPE)
- Birdshot chorioretinopathy
- Multiple evanescent white dot syndrome (MEWDS)
- Multifocal choroiditis and panuveitis (MCP)
- Punctate inner choroidopathy (PIC)
- Serpiginous choroiditis
Each of these syndromes has unique characteristics, but they all involve inflammation and damage to the retina and/or choroid.
Symptoms
Symptoms of white dot syndromes can vary depending on the specific syndrome, but may include:
- Blurred vision
- Floaters
- Photopsia (flashes of light)
- Scotoma (blind spots)
- Eye pain
Diagnosis
Diagnosis of white dot syndromes typically involves a thorough eye examination, including a dilated eye exam and imaging tests such as fluorescein angiography and optical coherence tomography (OCT).
Treatment
Treatment for white dot syndromes often involves reducing inflammation and preserving vision. This may include the use of corticosteroids, immunosuppressive drugs, and in some cases, laser therapy.
