Based on the available reference, it seems there might be a misunderstanding in the question. The reference mentions Punctate Inner Choroidopathy (PIC), not "pic disease." Therefore, this answer will address what Punctate Inner Choroidopathy (PIC) is.
PIC, or Punctate Inner Choroidopathy, is a rare eye condition characterized by inflammation in the back of the eye.
Understanding Punctate Inner Choroidopathy (PIC)
PIC is a condition that primarily affects the choroid, a layer of blood vessels located beneath the retina. The "punctate" part of the name refers to the small, distinct spots that appear in the choroid during the disease.
Key Features of PIC:
- Rare Condition: PIC is not a common eye disorder.
- Inflammation: The primary cause is inflammation within the eye.
- Location: The inflammation occurs at the back of the eye, specifically in the choroid.
- Demographics: PIC is more frequently observed in women. The reference also notes it's more common in short-sighted people.
- Vision Impact: PIC can lead to vision problems if left untreated.
Risk Factors:
- Female Gender: Women are more likely to develop PIC.
- Myopia (Short-sightedness): Individuals with myopia have an increased risk.
Diagnosis:
Diagnosis usually involves a comprehensive eye exam, including:
- Fundoscopy: Examining the back of the eye with an ophthalmoscope.
- Optical Coherence Tomography (OCT): An imaging technique to visualize the layers of the retina and choroid.
- Fluorescein Angiography: A procedure where dye is injected into the bloodstream to visualize blood flow in the retina and choroid.
Treatment:
Treatment often involves managing the inflammation, typically with:
- Corticosteroids: To reduce inflammation.
- Immunosuppressants: In severe cases, to suppress the immune system.
