Retinitis Pigmentosa (RP) is a genetic condition leading to gradual vision loss. Our eye doctors provide comprehensive care and support for those living with RP.
Retinitis Pigmentosa (RP) is a group of rare, inherited eye diseases that gradually cause the cells in the retina to break down, leading to progressive vision loss. This condition affects the light-sensitive layer of tissue at the back of the eye, making it a significant focus for our eye doctors. Understanding RP is essential so patients and their families can manage vision changes through early detection and supportive care.
Retinitis Pigmentosa (RP) refers to a collection of genetic disorders that affect the retina, the part of the eye responsible for converting light into signals that the brain interprets as vision. In RP, the photoreceptor cells, which include rods and cones, gradually degenerate due to gene mutations. These genetic mutations interfere with the retina's ability to process light normally, leading to a slow and steady decrease in vision.
The condition is present at birth, but the symptoms may not become apparent until childhood or early adulthood. Because RP progresses differently among individuals, some patients may experience a slow decline in vision over many years, while others notice more rapid changes. While there is currently no cure for RP, various supportive strategies, including vision aids and rehabilitation programs, can help patients make the most of their remaining sight.
RP presents with a characteristic set of visual symptoms that slowly emerge and worsen over time. One of the earliest signs of RP is difficulty seeing in low-light conditions or at night—a symptom commonly referred to as night blindness.
Parents often observe that children with RP struggle to navigate in dim settings, indicating the onset of the condition. As RP progresses, the following symptoms are typically observed:
In some cases, the progression of visual loss can vary significantly from person to person. While many patients eventually lose most of their peripheral vision and have diminished central vision, the rate at which these changes occur differs, underscoring the importance of regular monitoring.

RP is fundamentally a genetic condition resulting from mutations in the genes that control the function and survival of retinal cells. These mutations interfere with the natural process by which the retina processes light, leading to the gradual death of photoreceptor cells. Since RP is inherited, it is passed down from generation to generation in families.
The inheritance patterns of RP can vary and include autosomal dominant, autosomal recessive, and X-linked forms. Here’s what that means in everyday terms: the specific gene mutation responsible for RP can be transmitted in different ways, affecting not just the patient but potentially future generations, making genetic counseling a recommended step for affected families.
Occasionally, RP may be associated with other genetic syndromes, such as Usher syndrome, which also causes hearing loss. In rare instances, environmental factors like certain medications, infections, or eye injuries can lead to a similar degeneration of retinal cells, but these causes are much less common compared to the genetic origins of RP.
Early and accurate diagnosis of RP is crucial for managing the condition effectively. Our eye doctors typically begin with a comprehensive dilated eye exam that carefully examines the retina for signs of deterioration. During this exam, special eye drops are used to dilate the pupils, allowing a better view of the back of the eye.
After the initial examination, several specialized tests may be conducted to confirm the diagnosis:
This diagnostic process not only helps in confirming RP but also assists our eye doctors in tailoring a personalized management plan for each patient. The tests are performed in a routine, comfortable environment, ensuring that patients feel supported throughout the process.
