Congenital Bile Acid Synthesis Disorder (CBASD) is a rare metabolic condition that prevents the body from producing primary bile acids, which are essential for absorbing fat-soluble vitamins such as Vitamin A and E. Without these nutrients, the retina and optic nerve can deteriorate over time, leading to progressive vision loss if the underlying metabolic condition is not treated. Specialized metabolic and retinal diagnostic services for this condition are scarce across Tanzania. Optic Atrophy Treatment Center works with Tanzanian families exploring stem cell therapy for the eye/vision component of CBASD.
As a rare metabolic-genetic condition, CBASD requires coordinated care across metabolic medicine, genetics, and ophthalmology that is difficult to access within Tanzania. Families often travel abroad to access specialized retinal/optic nerve evaluation and explore regenerative treatment options for the progressive vision loss, alongside bile acid replacement therapy managed by a metabolic specialist.

Stem cell therapy is studied for its potential to help support optic nerve tissue affected by Costeff Syndrome. It addresses the vision component only — the movement-related features (chorea, spasticity) require ongoing management by a neurologist.
Suitability depends on the stage of retinal/optic nerve involvement and how well the underlying metabolic condition is controlled. Before travelling, our team reviews:

I came from overseas specifically for treatment. The staff not only assisted me with transport but also made the whole experience hassle-free. The medical service was of the highest standard and I was very secure in Delhi

Your family is very thankful to stem cell cure india for being there for us. The doctors were very understanding and the staff made it a point to see that we were comfortable during the treatment. It was a very calming experience
” No — these are three distinct genetic conditions. CBASD specifically involves an inability to produce primary bile acids, which secondarily damages the retina and optic nerve through fat-soluble vitamin deficiency”
“No. Bile acid replacement therapy and vitamin supplementation, managed by a metabolic specialist, remain the priority. Our evaluation addresses the resulting eye/optic nerve damage.”
” Serum bile acid analysis, genetic test results if available, ERG results, and OCT scan.”
“Yes. Once treatment is confirmed, we provide the invitation and supporting documents Tanzanian citizens need to apply for a Medical Visa through the Indian High Commission in Dar es Salaam.”
