Punctate Inner Choroidopathy: Signs, Causes, and How to Treat

Punctate Inner Choroidopathy (PIC) is a rare eye condition that affects the choroid, a layer of blood vessels beneath the retina. In PIC, small, yellowish-white spots develop in the choroid, potentially impacting vision. The exact cause of PIC is not fully understood, but it is believed to be related to an abnormal immune response targeting the choroid.

This condition mainly affects young adults, particularly women, and is often associated with myopia (nearsightedness). While the spots can lead to vision changes, PIC typically does not cause severe vision loss. Understanding the underlying mechanisms of PIC and its specific triggers remains an ongoing area of research in the field of ophthalmology. If you suspect you may have PIC or

What Are the Symptoms of Punctate Inner Choroidopathy?

Punctate inner choroidopathy (PIC) can cause various eye symptoms. Patients may experience vision disturbances such as floaters, blurry vision, or blind spots in their central vision. Some individuals with PIC may also notice flashes of light or changes in color vision. Additionally, a decrease in visual acuity, especially in one eye, can be a common symptom. It is essential to consult an eye care professional if you experience any of these symptoms to receive a proper diagnosis and appropriate management.

Causes of Punctate Inner Choroidopathy

This condition is commonly seen in young myopic women and often occurs in individuals with a history of autoimmune diseases. Additionally, genetic predisposition may play a role in the development of PIC. While the exact cause of PIC is not fully understood, these factors are thought to contribute to the onset and progression of this rare eye disorder.

Types Of Punctate Inner Choroidopathy

Types include classic PIC, which involves multiple yellow-white lesions in the posterior pole, and multifocal choroiditis, characterized by scattered lesions. Subretinal fibrosis can develop in chronic cases. Another variant is the acute exudative polymorphous vitelliform maculopathy, where yellowish subretinal deposits appear. Additionally, patients may exhibit a pattern resembling acute macular neuroretinopathy. The diversity of PIC types underscores the complexity of this condition and the importance of accurate diagnosis and management strategies.

Risk Factors

While the exact cause is unknown, several risk factors have been identified. These include a history of myopia, a family history of autoimmune diseases, and genetic predisposition. Additionally, individuals who smoke or have a history of viral infections may have an increased risk of developing PIC. Proper management and regular eye exams are essential for detecting and addressing this condition early to prevent vision loss.

Diagnosis of Punctate Inner Choroidopathy

The process may include a thorough review of the patient's medical history and symptoms, as well as imaging tests such as optical coherence tomography (OCT) and fundus autofluorescence (FAF) to visualize the choroid and retinal layers. Fluorescein angiography may also be used to assess blood flow within the eye. Additionally, a visual field test and electroretinography (ERG) may help evaluate the retinal function. These various methods collectively aid in the accurate diagnosis of Punctate Inner Choroidopathy, guiding the appropriate management and treatment plan for the patient.

Treatment for Punctate Inner Choroidopathy

Punctate inner choroidopathy (PIC) is a rare inflammatory eye condition primarily affecting young myopic women, characterized by inflammation in the inner choroid layer of the eye. Treatment options aim to manage inflammation, preserve vision, and prevent complications. Corticosteroids, such as oral prednisone or intraocular injections, are commonly prescribed to reduce inflammation. In cases where corticosteroids alone are insufficient, immunosuppressive agents like azathioprine or mycophenolate mofetil may be used for long-term management. 

For patients experiencing choroidal neovascularization, anti-VEGF injections can help address this complication. Regular monitoring through eye exams is essential to detect any progression of the disease and adjust treatment as necessary. Additionally, lifestyle modifications, including quitting smoking and maintaining a healthy diet, can further support overall eye health. For individuals with mild or asymptomatic cases, observation and monitoring may be sufficient.
