Retinitis Pigmentosa

Retinitis Pigmentosa is an inherited eye disease that slowly affects vision, leading to night blindness and gradual loss of sight.
Symptoms:

Retinitis Pigmentosa slowly damages the retina, causing night blindness, loss of peripheral vision, and difficulty seeing in dim light. Over time, central vision may also blur, making daily activities like driving or reading increasingly hard.

Symptoms usually begin gradually and can vary from person to person.

  • Night blindness — trouble seeing in dim light or at night
  • Loss of peripheral (side) vision — “tunnel vision”
  • Difficulty adjusting between dark and bright environments
  • Trouble seeing moving objects or navigating crowded spaces
  • In later stages, reduced central vision and possible blindness
What is Retinitis Pigmentosa ?

Retinitis Pigmentosa (RP) is a rare inherited eye disorder that gradually damages the retina, the light-sensitive tissue at the back of the eye. It mainly affects photoreceptor cells called rods and cones, which help people see in dim light and detect colors and details. The condition usually begins with night blindness and difficulty seeing in low-light environments. As the disease progresses, peripheral vision slowly decreases, often leading to tunnel vision. In advanced stages, central vision may also be affected.

RP is caused by genetic mutations passed down through families, and symptoms can appear during childhood, adolescence, or adulthood. The progression and severity vary from person to person.

Doctors diagnose RP through eye examinations, visual field tests, retinal imaging, and genetic testing. Although there is currently no complete cure, treatments such as low-vision aids, vitamin therapy under medical supervision, and certain gene therapies may help manage symptoms and slow progression. Early diagnosis and regular eye care are important for preserving vision and improving quality of life.

Various Stages in Retinitis Pigmentosa :
Stage 1: Early Stage – Night Blindness (Nyctalopia) Rod cells (responsible for low-light and peripheral vision) begin dying first. The patient notices difficulty seeing in dim light or at night – struggling to walk in a dark room, navigate in theaters, or drive after sunset . Daytime vision and central vision remain normal at this stage.
Stage 2:Early-Mid Stage – Loss of Peripheral (Side) Vision A ring-shaped blind spot (peripheral ring scotoma) develops around the central vision . The patient starts bumping into objects on the sides, has trouble with peripheral awareness while driving, or misses people approaching from the side . This is often described as gradually narrowing visual field.
Stage 3: Mid Stage – Tunnel Vision Develops Peripheral vision loss worsens, leaving only a small circular area of central vision – like looking through a narrow tunnel . The patient can still read, recognize faces, and see details straight ahead. Color vision and visual acuity may begin declining slightly .
Stage 4. Mid Stage – Tunnel Vision Develops Peripheral vision loss worsens, leaving only a small circular area of central vision – like looking through a narrow tunnel . The patient can still read, recognize faces, and see details straight ahead. Central vision (macula) begins deteriorating as cone cells (for color vision) also degenerate
Stage 5 . Late Stage – Severe Tunnel Vision with Central Vision Decline The tunnel of central vision shrinks further; some patients retain only a tiny central spot.
Stage 6 . End Stage – Legal Blindness (But Complete Blindness Is Extremely Rare) Some patients reach legal blindness (visual acuity ≤20/200 or visual field
