Rod and cone dystrophies are inherited conditions that affect both night vision and daytime colour and detail. This page explains the condition for families in South Africa, what support is available and how stem cell therapy is assessed.

In a rod-cone dystrophy, night and side vision fade first. In a cone-rod dystrophy, glare, poor colour vision and loss of central sharpness come first. The ERG pattern and the genetic result decide which label fits.
Stem cell therapy for this condition is still experimental. It is not an approved standard treatment by regulators such as SAHPRA in South Africa or the US FDA, and results differ from person to person. We cannot promise any particular outcome.
These are the complaints we hear most often.
Several tests are combined to build a full picture.
A full-field ERG separates rod and cone responses.
OCT and autofluorescence imaging show which layers are thinning.
Inherited retinal conditions are being studied in South African families, so ask about local genetic research.
Helps families understand how the condition is inherited and plan ahead.
Good support makes daily life easier at every stage.
A patient organisation focused on inherited retinal disease, offering information and community.
Training, assistive technology and rehabilitation.
Ask the school about seating, large print and extra time, and any provision for learners with low vision.
Licensing has vision standards, so plan alternatives early.
Parents or guardians are welcome at assessments for children, and any decision about therapy for a minor should be made carefully by both parents together. Send reports by WhatsApp or email first. India is about three and a half hours ahead of South Africa, and we can provide a visa support letter.
