We may be losing our sight, but we are holding onto our vision in this race against time. Join our global community dedicated to finding a cure for Bietti’s Crystalline Dystrophy (BCD).

Bietti’s Crystalline Dystrophy (BCD) is a rare, often misdiagnosed genetic eye disease that causes blindness for 100,000 people globally. 

Right now, there is no proven treatment, but there is hope. With your help, we can push BCD gene therapy research from pre-clinical study to human clinical trial.

Our Priorities

Advance Treatment Development

Fund the ongoing gene therapy led by a patient, which shows promise for a treatment that would help halt the deteriorating sight for many and prevent thousands more from the experience of losing their sight to BCD.

Improve the Correct Diagnosis

BCD often goes misdiagnosed, taking years for patients to understand what is happening with their vision. Raise awareness of BCD with us so more patients can be correctly diagnosed.

Raise Awareness with Us

Follow us and share our posts. Together, we can reach more BCD patients and families. With more awareness and knowledge of BCD, more people can be correctly diagnosed. 

What is BCD?

Our world is getting dimmer and blurrier, sending us to blindness, as Bietti’s Crystalline Dystrophy (BCD) progresses. But the ongoing gene therapy offers hope to halt the deteriorating sight.

How to Spot BCD?

Small yellow-white crystals are visible clinically in the retina and sometimes also in the cornea.

However, retinal crystals may not be obvious in early- or late-stage patients.

Crystals may not be obvious in early or late stages, but near-infrared imaging can enhance the detection of crystals
BCD is often misdiagnosed as RP or Stargardt disease. Use CYP4V2 gene test to diagnose or confirm BCD


Night blindness, distorted vision, photophobia

Impaired Visual Field & Visual Acuity

Who We Are

Invincible Vision is a non-profit organization and global community dedicated to finding a cure for BCD. Started by a small group of people touched by BCD, it has quickly grown to include more patients, families, and friends around the world who believe in the invincible vision that we can find a treatment together.

Why are rare diseases so difficult to diagnose?

🌀Wide range of symptoms
🌎Scattered expertise around the world
🧑‍⚕️Not easy for primary care professionals to choose the correct specialist
