Retinitis pigmentosa (RP) is a cluster of inherited eye disorders that affect the retina, the light-sensitive tissue at the back of the eye. It is caused by genetic mutations in over 100 different genes that affect the function of the retina's photoreceptor cells (rods and cones). These genetic mutations lead to a progressive degeneration of the photoreceptor cells, causing a slow loss of vision. The first symptom is usually difficulty seeing in low light (night blindness), followed by a gradual loss of peripheral vision and eventually central vision. There is currently no cure, but treatments like vitamin A supplements and gene therapy are being researched to try to slow the progression of vision loss.
Delhi, India's capital city known for its rich history and diverse culture, has seen its fair share of genetic disorders like RP cases. The residents of Delhi can rest assured that Apollo Hospitals is equipped with some of the best doctors for retinitis pigmentosa treatment and retinitis pigmentosa specialists who are well-trained to manage this rare disease effectively.
Types/Stages of Retinitis Pigmentosa
The key types of RP include:
-
Typical RP: This is the most common form inherited in an autosomal dominant, autosomal recessive, or X-linked manner. It is characterised by loss of peripheral vision and night blindness.
-
Usher Syndrome: Usher syndrome is a type of RP associated with hearing loss, and in some cases, with vestibular problems.
-
Leber's Congenital Amaurosis: This is a severe form of retinal dystrophy that presents at birth or within the first few months of life, leading to severe visual impairment or blindness.
-
Other Syndromic Forms: Some forms of RP are associated with other systemic or neurologic abnormalities, such as Bardet-Biedl syndrome, Senior-Loken syndrome, and Alström syndrome.
-
Other Non-syndromic Forms: There are many other non-syndromic forms of RP, each associated with specific genetic mutations and inheritance patterns.
Symptoms of Retinitis Pigmentosa
The symptoms of RP progress gradually and include:
-
Night blindness
-
Peripheral vision loss
-
Difficulty adjusting to light changes
-
Color vision problems
-
Central vision loss
Tests to Diagnose Retinitis Pigmentosa

-
Electroretinogram: The most important diagnostic test providing an objective measure of rod and cone function across the retina.
-
Genetic Testing: Identifying the specific genetic mutation causing the retinal degeneration is critical for diagnosis and prognosis.
-
Visual Field Testing: This test is used to map the progressive loss of peripheral vision in patients with RP.
-
Ophthalmoscope Exam: The doctor examines the retina for signs like retinal pigment changes, arteriolar attenuation, and optic nerve pallor.
