Retinitis Pigmentosa — Overview
Retinitis pigmentosa (RP) is a group of inherited retinal disorders that gradually damage the light-sensitive cells of the retina. This leads to progressive vision loss, beginning with difficulty seeing at night and eventually affecting peripheral and central vision over time.
Traditional management options aim to slow vision deterioration but cannot regenerate damaged photoreceptor cells. Stem cell therapy, however, introduces regenerative potential by restoring impaired retinal cells, improving retinal function, and supporting visual clarity.
At Viezec, our advanced regenerative medicine programs focus on protecting, repairing, and revitalizing retinal tissue using ethically sourced stem cells — designed to preserve and enhance long-term vision quality for RP patients.
How Stem Cells Help in Retinitis Pigmentosa (RP)
Retinitis pigmentosa (RP) is a group of inherited retinal disorders that gradually destroy the light-sensitive cells of the retina. Patients typically experience night blindness, tunnel vision, and progressive loss of peripheral and central sight, which may eventually lead to severe visual impairment or blindness. The slow degeneration significantly affects mobility and independence in daily life.
Stem cell therapy, especially with mesenchymal stem cells (MSCs), supports retinal repair by replacing or rejuvenating damaged photoreceptor and retinal pigment epithelial cells. MSCs secrete neuroprotective and anti-inflammatory molecules that enhance retinal cell survival, improve microcirculation, and slow disease progression—helping stabilize or restore visual function in RP patients.
Causes of Retinitis Pigmentosa
Retinitis pigmentosa (RP) is a group of inherited retinal disorders caused by progressive loss of photoreceptor cells, primarily the rods, which impairs night vision and peripheral sight. Multiple genetic, cellular, and environmental mechanisms interact to produce the characteristic degeneration of the retina seen in RP.
- Inherited gene mutations: Variants in dozens of genes that affect photoreceptor structure or function are the primary cause of RP.
- Mode of inheritance: Autosomal dominant, autosomal recessive, and X-linked patterns influence disease onset, severity, and family risk.
- Photoreceptor cell death: Dysfunctional rods (and later cones) undergo apoptosis, leading to progressive vision loss over years.
- Oxidative and metabolic stress: Impaired cellular metabolism and reactive oxygen species accelerate photoreceptor degeneration.
- Retinal pigment epithelium dysfunction: Defects in the RPE impair photoreceptor support, waste clearance, and nutrient transport to the retina.
- Modifier and environmental factors: Light exposure, systemic health, and other genetic modifiers can affect progression and symptom severity.
Early genetic diagnosis and monitoring help guide prognosis and emerging therapies. At Viezec, our regenerative medicine team evaluates underlying causes to design individualized strategies aimed at preserving retinal function and slowing decline.
Symptoms of Retinitis Pigmentosa (RP)
Retinitis pigmentosa is a group of inherited retinal disorders that gradually damage the light-sensitive cells of the eye. Symptoms typically begin with night vision problems and slowly progress to peripheral vision loss. Recognizing early signs helps in managing the condition and protecting remaining vision.
- ✅ Difficulty seeing in dim light or at night
- ✅ Gradual loss of peripheral (side) vision
- ✅ Tunnel vision—seeing only objects straight ahead
- ✅ Sensitivity to bright light or glare
- ✅ Slower adjustment of eyes when moving from light to dark environments
⚠️ Important: Consult an eye specialist if you experience night blindness, shrinking side vision, or increased glare sensitivity. Early detection allows timely interventions and helps slow further vision deterioration.
Diagnosis of Retinitis Pigmentosa
Accurate diagnosis of Retinitis Pigmentosa (RP) is essential for genetic counselling and preserving remaining vision. At Viezec, our team employs advanced retinal imaging and functional tests to assess photoreceptor health and map the progression of RP.
Standard Diagnostic Tests Include:
- Comprehensive Eye Examination: Full retinal inspection to identify bone-spicule pigmentation, optic disc changes, and peripheral retinal degeneration.
- Optical Coherence Tomography (OCT): High-resolution cross-sections to evaluate photoreceptor layer integrity and retinal thickness.
- Electroretinography (ERG): Measures retinal electrical responses to light and quantifies rod and cone function decline typical of RP.
- Visual Field Testing: Assesses peripheral field loss and scotomas to monitor disease progression and functional vision impact.
🩺 Clinical Credibility: All RP diagnostic evaluations at Viezec are performed under the guidance of retina specialists and ophthalmologists, following international best practices. This ensures precise staging, genetic investigation where appropriate, and careful planning before any regenerative therapy or intervention is considered.
Stem Cell Treatment for Retinitis Pigmentosa
How It Works
Stem cell therapy for retinitis pigmentosa (RP) focuses on preserving peripheral and central vision by targeting the progressive degeneration of photoreceptors and their supportive retinal environment. Transplanted cells—derived from mesenchymal stem cells (MSCs) or pluripotent cell lines—can provide trophic support, replace damaged retinal cells, and attenuate harmful inflammation. These cells release growth factors and neuroprotective cytokines that help stabilise surviving photoreceptors, enhance local metabolic support, and promote synaptic repair. In selected patients this combined protective and regenerative activity can slow the course of degeneration and create potential for modest visual improvement or improved night and peripheral vision function over time.
Procedure at Viezec
At Viezec, RP interventions follow a patient-centred protocol developed by retinal specialists and regenerative medicine experts. Every phase—from eligibility screening through rehabilitation—is carried out in accordance with international standards inside GMP-certified facilities to guarantee cell integrity, sterility, and traceability across the treatment pathway.
- Comprehensive retinal imaging and functional testing to determine candidacy
- Selection and collection of autologous or donor stem cell material
- Cell expansion, differentiation as needed, and strict GMP processing
- Targeted delivery via subretinal, intravitreal, or systemic routes based on disease pattern
- Post-treatment monitoring, vision therapy, and scheduled follow-up assessments
Expected Outcomes
Many patients experience stabilization of visual field loss and occasional measurable gains in functional vision, such as improved night vision, contrast sensitivity, or reading ability, typically observed within 3–6 months after therapy. While dramatic recovery of long-lost vision is uncommon—particularly in advanced RP—clinical experience indicates that regenerative approaches can reduce the pace of degeneration, preserve remaining photoreceptors, and enhance daily visual performance for a portion of treated individuals.
Disclaimer: Outcomes depend on disease stage, genetic subtype of RP, patient age, and prior treatments. All procedures at Viezec are conducted under specialist medical supervision and are intended to complement established retinal care rather than replace it.

Mechanism of Action: How Stem Cells Support Retinal Repair in Retinitis Pigmentosa
Stem cell therapy for Retinitis Pigmentosa (RP) focuses on restoring and preserving the photoreceptor layer that progressively degenerates due to genetic or metabolic dysfunction. Instead of simply replacing dead retinal cells, stem cells serve as biological repair agents—secreting growth factors, cytokines, and neuroprotective molecules that help maintain surviving retinal tissue and slow further vision loss.
- Photoreceptor Preservation: Stem cells release neurotrophic factors that protect and nourish remaining rod and cone cells, delaying degeneration.
- Retinal Microenvironment Repair: They help rebuild supportive tissue and improve intercellular communication within the retinal structure.
- Anti-inflammatory and Immune Balance: Stem cells regulate immune responses that trigger retinal damage, minimizing inflammation and apoptosis.
- Enhanced Oxygenation and Nutrient Supply: By promoting angiogenic signaling, stem cells improve local circulation and metabolic support for retinal cells.
This holistic regenerative approach underscores the potential of mesenchymal stem cells (MSCs) in addressing both early and advanced stages of RP. At Viezec, each treatment adheres to strict clinical standards ensuring safety, therapeutic accuracy, and ethical compliance for every individual patient.
