BCD or Bietti’s crystalline dystrophy is a genetic condition that causes fatty acid crystals to accumulate in the retina and cornea. The retina is the light-sensitive tissue layer in the back of your eye, and the cornea is the clear layer at the eye’s front.
The first symptoms of people with this condition are usually in their teenage years or 20s, such as blurry peripheral vision (vision from the eye’s corner) and in low light, which may gradually result in vision loss.
There is no available treatment for BCD, but rehabilitation of vision can help patients maximise their vision.
The first symptom is often a vision change. You may notice that your vision isn’t as clear as it used to be. The symptoms include:
BCD can affect both eyes, but one eye often gets worst faster than the other. The symptoms may also worsen over time. Most people with BCD lose all or most of their vision. Many BCD patients see things in their central vision, which is usually blurry.
Your risk of BCD may be higher if:
BCD is a rare genetic condition, meaning it is passed from parents to offspring. You will only experience the symptoms if your parents have the gene for BCD and it is passed to you. If only one of your parents has the gene, you will be a BCD gene carrier but will not have the symptoms.
A comprehensive dilated eye examination will help your doctor check for BCD. This exam is painless and simple. The doctor will give you some eye drops to widen (dilate) your pupil, then check for the disease.
Your doctor may also conduct genetic testing to confirm if you have BCD. These tests check for changes in the BCD gene (CYP4Vgene2).
Treatment for BCD
No permanent treatment is currently available for treating BCD. Living with low vision or vision loss resulting from BCD is usually challenging. Daily tasks will become more difficult even with contact lenses, glasses, surgery or medicine if you have low vision. However, options are available to help, such as rehabilitation programs and low-vision devices and support.

Dr Mani has performed more than 20,000 ophthalmic procedures, including LASIK, LASEK, PRK, Femto Cataract, RLE, Lens ICL and Phakic IOL Surgery
I had a great experience performing my laser eye surgery at Optimal Vision Clinic. All the staffs are very helpful, co-operative and supportive throughout the treatment process. On the first call, they explained the entire procedure in details and gave necessary instructions at every stage. My eye surgeon made me feel comfortable and relaxed before and during the procedure. Aftercare was done properly with a thorough check-up of my eyes. I would like to recommend this clinic to everyone!
Very happy and impressed with the highly professional care and service I’ve received at the Optimal Vision clinic. Dr Mani is so professional, and he explained everything about Laser surgery and answered all my questions. The surgery was quick and almost completely painless. My eyes have healed perfectly and quickly. I would highly recommend this clinic.
My husband had been experiencing discomfort in his left eye since July and was seen by various doctors/consultants even at the Queen Mary’s hospital but no abnormalities were found.
This week Dr. Mani discovered the fault which happened to be Retina detachment with three tears.
Dr. Mani’s preciseness and his perfectionist attitude to attention to details, detected the source of the main issue and saved my husband’s eye. We feel utterly grateful and can not recommend him enough for his excellence.
