Genetic Disorder

Retinitis Pigmentosa

MODERATE

A group of inherited retinal dystrophies causing progressive vision loss due to photoreceptor degeneration. Most common inherited retinal disease. Can be isolated or part of syndromes (Usher syndrome, Bardet-Biedl syndrome).

Risk Factors

1Family history
2Genetic mutations
3Consanguinity
4Advanced paternal age
5Ethnic predisposition

Diagnostic Methods

  • 1Genetic testing
  • 2Clinical evaluation
  • 3Family history assessment
  • 4Specialized laboratory tests
  • 5Imaging studies
  • 6Biopsy (if applicable)

Prognosis

Variable progression. Legal blindness by age 40 in many cases. Some forms progress rapidly, others slowly. Cataracts common and treatable. No effect on lifespan.

Prevention

  • Genetic counseling
  • Carrier screening
  • Prenatal diagnosis
  • Preimplantation genetic diagnosis
  • Family planning

Research Status

Gene therapy (Luxturna for RPE65) approved. Vitamin A palmitate may slow progression. Retinal prosthetics (Argus II) available. CRISPR trials ongoing. Many gene-specific therapies in development.
