Definition
Meaning and Definition
A genetic eye disease causing progressive retinal degeneration and loss of vision.
A group of inherited retinal dystrophies characterized by the gradual breakdown and loss of photoreceptor cells, specifically rods and then cones, often leading to tunnel vision and eventual blindness.
Dialectal Variation
British vs American Usage
Differences
No significant differences in meaning or usage; it is a standard international medical term. Spelling may occasionally differ in derivative adjectival forms (e.g., 'retinitis pigmentosa-related' vs. 'related to retinitis pigmentosa'), but the core term is invariant.
Connotations
None beyond the clinical definition.
Frequency
Equally rare and used only in specialist medical contexts (ophthalmology, genetics, optometry) in both dialects.

- Assuming it is an infectious or inflammatory condition from the '-itis' suffix.
FAQ
Frequently Asked Questions
No, it is an inherited genetic disorder and cannot be spread from person to person.
Currently, there is no cure, but research into gene therapy, retinal implants, and pharmaceutical treatments is ongoing to slow progression or restore some vision.
The suffix '-itis' denotes inflammation. This is a historical misnomer, as inflammation is not a primary feature of the disease; it is primarily a degenerative condition.
Diagnosis typically involves a combination of a detailed patient history, visual field testing, electroretinography (ERG) to measure retinal cell function, and ophthalmoscopic examination to observe the characteristic retinal pigmentation.
A genetic eye disease causing progressive retinal degeneration and loss of vision.
Retinitis pigmentosa is usually medical/specialist in register.
Retinitis pigmentosa: in British English it is pronounced /ˌrɛtɪˈnaɪtɪs ˌpɪɡmɛnˈtəʊsə/, and in American English it is pronounced /ˌrɛt̬əˈnaɪt̬ɪs ˌpɪɡmɛnˈtoʊsə/. Tap the audio buttons above to hear it.
Learning
Memory Aids
Mnemonic
Think: RETINA + 'itis' (inflammation) + PIGMENT-osa (pigmented spots). The retina develops pigment spots, leading to sight loss.
Conceptual Metaphor
Vision as a narrowing tunnel (due to peripheral vision loss).
