Living with Oguchi disease
An inherited eye condition with night blindness present from birth that does not get worse over time.
Understanding Oguchi disease
It is marked by congenital stationary night blindness and the Mizuo-Nakamura phenomenon, a change in how the retina looks after time in the dark. Retina tests (electroretinograms) show reduced responses. GARD lists newborn and infant years as the usual onset.
Signs & symptoms
Symptoms vary from person to person. GARD lists these among the most common:
- Night blindness from birth that does not worsen
- Mizuo phenomenon (a retina color change after dark adaptation)
- Reduced dark-adapted response on an electroretinogram
Not everyone has every symptom. GARD's list comes from the Human Phenotype Ontology.
Diagnosis
- 1Talk with your doctor
Share the symptoms you've noticed, when they started and your family health history. Notes and photos can help.
- 2See a specialist
Specialists who may be involved include eye disease specialists and genetic specialists.
- 3Ask which tests can help
Your care team will decide which exams and tests can confirm the diagnosis.
Care & treatment
- Care team
- Eye disease specialists (ophthalmologists); Genetic specialists (geneticists)
- Expert care
- Ask about multidisciplinary care centers for rare conditions
- Treatment
- GARD doesn't list specific treatments for this condition. Your care team will tailor care to your symptoms.
- Research
- Clinical trials and observational studies may be options. See the research section below.
General information, not medical advice. Your care team makes the decisions.
Everyday life
Living with a rare condition is easier with support.
- Connect with rare disease patient organizations for support
- Keep notes on symptoms, changes and questions for appointments
- Ask about patient registries that help research
- Look into financial aid and travel resources for care visits
Quick facts
GARD says changes in genes cause this condition. It is inherited in an autosomal recessive way, meaning a child inherits a changed copy of the gene from each parent.
Also known as: congenital stationary night blindness, oguchi type; oguchi syndrome; oguchi's disease
