    The study analyzed 506 patients with retinitis pigmentosa (RP) to assess how age influences genetic detection and clinical characteristics.

  • 2

    Detection rates of causative genes for RP decreased significantly with age, from 39.7% in patients under 40 to 3.0% in those aged 80 and older.

  • 3

    The mean age of participants was 58.8 years, with a distribution across six age groups, highlighting the study's diverse patient demographics.

  • 4

    Significant differences in age at onset were observed among causative genes, with RPGR showing the earliest onset at a mean age of 5.2 years.

  • 5

    The findings suggest that lower genetic detection rates in older patients may reflect characteristics associated with late-onset retinitis pigmentosa.
