X-Linked Retinitis Pigmentosa (XLRP) is a severe form of inherited retinal degeneration. Because the gene is located on the X chromosome, it primarily affects males, leading to progressive loss of "photoreceptor" cells in the retina.

Symptoms often begin in childhood with "nyctalopia" (night blindness). This is followed by a gradual narrowing of the peripheral visual field, commonly known as "tunnel vision."
By the third or fourth decade of life, many individuals experience significant central vision loss. Unlike other forms of RP, the X-linked variety tends to progress more rapidly toward legal blindness.
While there is no cure, gene therapy trials are currently underway. Patients are advised to use low-vision aids and protect their eyes from excessive UV light exposure.
Most carriers have normal vision, but some may show subtle retinal changes or mild night vision issues later in life.
While not usually apparent at birth, genetic testing can identify the mutation early if there is a known family history.
Some doctors recommend Vitamin A palmitate or Omega-3, but you must consult a retinal specialist before starting any high-dose supplements.
