Punctate Inner Choroidopathy (PIC) is a rare inflammatory eye disease that can affect your vision. Early detection and monitoring are crucial to maintaining eye health.
Punctate Inner Choroidopathy (PIC) is a rare inflammatory condition that affects a crucial layer of the eye known as the choroid, situated just beneath the retina. This disorder is primarily seen in young, nearsighted women between the ages of 18 and 40, and it can lead to tiny inflammatory lesions at the back of the eye. Early recognition and careful monitoring are essential in maintaining overall vision health and preventing potential complications.
PIC is a specific type of inflammatory eye disease that targets the choroid, a layer rich in blood vessels that supports the function of the retina. The inflammation results in small spots—tiny lesions—that can be seen during an eye examination. Although the condition can sometimes resolve on its own, it is important to understand and monitor PIC because of the potential risk it poses to vision through complications like choroidal neovascularization (CNV), where abnormal blood vessels may develop under the retina.
Even though the exact trigger of PIC remains unknown, research suggests that an autoimmune reaction is likely involved. In simple terms, the body’s immune system mistakenly attacks healthy tissue within the eye. Factors such as infections, vaccinations, or even stress could potentially act as triggers in individuals who are genetically predisposed to this condition. This immune system misfire leads to inflammation in the choroid, ultimately forming the characteristic spots that define PIC.
One of the challenges with PIC is that many individuals might not notice obvious signs of the condition at first. However, as the inflammation builds up, patients may experience a range of visual disturbances. Understanding these symptoms is key for early detection and maintaining good vision.
It is important to note that symptoms might develop gradually or sometimes appear more suddenly. While many patients maintain good vision despite these symptoms, any sudden changes warrant an evaluation by one of our eye doctors to ensure that complications such as CNV do not develop.

The diagnosis of PIC involves a series of examinations that allow our eye doctors to inspect the intricate layers of the eye closely. Since PIC affects the choroid and can produce subtle signs, a detailed diagnostic approach is necessary.
When you visit the clinic, your retina specialist will typically begin with a thorough dilated eye exam, examining the back of the eye for any signs of inflammation or lesions. To closely visualize these delicate layers, several imaging tests are often used:
Through these diagnostic tools, our eye doctors are able to pinpoint the extent of PIC, assess if both eyes are involved, and rule out other conditions that might mimic similar symptoms. Early and accurate diagnosis is a critical component in managing PIC effectively.
The exact origins of PIC remain elusive, which can understandably be a source of concern for those diagnosed with the condition. However, current understanding suggests that PIC is largely an autoimmune process. This means the body’s natural defense system mistakenly targets its own eye tissues, especially within the choroid.
Researchers believe there may be several factors that contribute to the development of PIC:
While the precise interplay of these factors is still under study, one thing is clear: managing inflammation and monitoring ocular health are key to preventing complications. Our eye doctors remain committed to following up regularly with patients affected by PIC, ensuring that any changes in the condition can be swiftly addressed.
