Understanding Your Diagnosis: Multifocal Choroiditis

At a Glance

Multifocal choroiditis (MFC) is a rare inflammatory eye condition causing spots of inflammation in the choroid and retina, mostly affecting nearsighted women. With modern treatments like steroids and biologics, doctors can control the inflammation and help patients maintain excellent vision.

Receiving a diagnosis of Multifocal Choroiditis (MFC) can feel overwhelming. It is entirely normal to feel anxious or scared, especially as a young person facing a chronic condition. While the name sounds complex, MFC is simply a rare inflammatory disease that affects the choroid (the layer of blood vessels under the retina) and the retina itself, usually in young to middle-aged women who are myopic (nearsighted) [1][2].

  • Multifocal: This means the inflammation appears in multiple separate spots or “lesions.”
  • Choroiditis: This simply means inflammation of the choroid.

Because MFC is rare, local eye doctors might have limited experience with it. However, the outlook today is far brighter than in the past. With modern treatments and “tight control” of inflammation, many patients maintain excellent vision [3][4].

Common questions in this guide

What is multifocal choroiditis (MFC)?
Multifocal choroiditis is a rare inflammatory disease affecting the choroid, which is the layer of blood vessels under the retina. It causes multiple separate spots of inflammation and typically affects young to middle-aged women who are nearsighted.
What are the symptoms of multifocal choroiditis?
Warning signs of an MFC flare-up include blurry blind spots, seeing wavy lines, or noticing flashing lights in your vision. If you experience these visual changes, you should be evaluated by your eye doctor promptly.
Is multifocal choroiditis treatable?
Yes, the outlook for MFC is very positive today. Doctors use medications like steroids and biologics to achieve tight control of the immune system, which stops inflammation and helps most patients maintain excellent vision.
What kind of doctor should treat MFC?
Because MFC is a rare condition, local eye doctors may have limited experience with it. It is highly recommended to build a care team that includes a uveitis specialist, who is an ophthalmologist specially trained in inflammatory eye diseases.
What is choroidal neovascularization (CNV) and how is it monitored?
Choroidal neovascularization is a complication where abnormal blood vessels grow under the retina, potentially threatening your vision. Your doctor will monitor your eyes regularly using OCT and FAF scans to detect and treat CNV or scar expansion early.

Questions to Ask Your Doctor

Curated prompts to bring to your next appointment.

  1. 1.Based on my imaging, do I have Multifocal Choroiditis (MFC) or Punctate Inner Choroidopathy (PIC), and what features (like lesion size or vitritis) distinguish them in my case?
  2. 2.What is my current risk for developing choroidal neovascularization (CNV), and how will we monitor for it?
  3. 3.Given the rarity of MFC, are you comfortable managing this long-term, or should I also see a uveitis specialist?
