Retinitis Pigmentosa in Grand Rapids, MI

Understanding inherited retinal disease, diagnosis, and local support

Retinitis pigmentosa (RP) is a group of inherited eye diseases that damage the light‑sensing cells in the retina and gradually affect vision. In Grand Rapids, Michigan, residents with RP can access advanced eye care through major health systems such as Corewell Health (formerly Spectrum Health), Trinity Health Grand Rapids, Metro Health – University of Michigan Health, and Mercy Health.

About the Retina

The retina is a thin layer of light‑sensitive cells at the back of the eye. It sends information about:

  • Shape
  • Color
  • Pattern
  • Movement

to the brain through the optic nerve.

The retina contains millions of special cells called rods and cones:

Rods and Cones Explained

  • Rods

    • More numerous than cones
    • Spread across the entire retina, with higher concentration in the periphery (edges)
    • Allow you to see what’s above, below, and to the sides of the object you’re looking at
    • One of their key functions is to help you see in low light or at night

  • Cones

    • Fewer in number than rods
    • Concentrated mainly in the center of the retina (the macula)
    • Help you distinguish colors and see fine detail (reading, recognizing faces, etc.)

When these rod and cone cells are damaged, vision gradually worsens.

What Is Retinitis Pigmentosa?

Retinitis pigmentosa (RP) is the name for a group of hereditary (genetic) retinal diseases that damage the rod and/or cone cells and cause vision to fade over time.

RP is part of a broader category called inherited retinal diseases (IRD). IRDs affect approximately 1 in every 3,000 Americans. The:

  • Severity of symptoms
  • Speed of progression
  • Age when symptoms first appear

can vary widely from person to person, even within the same family.

Symptoms of Retinitis Pigmentosa

RP usually progresses gradually, not suddenly. Early symptoms may be subtle, which is why regular eye exams with a Grand Rapids ophthalmologist are important.

Common Early Symptoms

  • Night blindness

    • Difficulty seeing in dim light (e.g., in Michigan’s long winter evenings, dim restaurants, or poorly lit parking lots)
    • Trouble adjusting from bright to dark environments

  • Peripheral (side) vision loss

    • Difficulty noticing curbs, steps, or obstacles to the side
    • Bumping into furniture or door frames
    • Trouble seeing people or objects that are not directly in front of you

As RP progresses, you may lose more of your peripheral vision, until only the very center of your visual field remains.

Tunnel Vision

When only the central part of your vision remains, this is called tunnel vision. To see what is above, below, or to the sides of what you are focusing on, you must move your eyes or head more often.

Other possible symptoms include:

  • Difficulty distinguishing colors
  • Trouble reading or seeing fine detail
  • Glare sensitivity

Because Michigan experiences frequent overcast days and glare from snow in winter, people with RP in Grand Rapids may notice more difficulty with changing light conditions.

Diagnosis of Retinitis Pigmentosa in Grand Rapids

If you notice any of the symptoms above, schedule a comprehensive eye exam with an ophthalmologist in Grand Rapids. Major centers such as Corewell Health – Helen DeVos Eye Center, Trinity Health Grand Rapids, and local retina specialists can perform detailed testing.

Common Tests for RP

A full assessment may include:

  • Comprehensive eye exam

    • Visual acuity (how clearly you see)
    • Pupil and lens examination
    • Dilated retinal exam

  • Visual field test

    • Measures your side vision and detects areas of vision loss

  • Electroretinography (ERG)

    • A specialized test that records the electrical activity of the retina
    • Shows how well rods and cones are functioning

  • Optical coherence tomography (OCT)

    • High‑resolution scans of the retina
    • Can detect swelling (macular edema) or thinning of retinal layers

  • Color vision testing

    • Checks for problems distinguishing colors

  • Retinal photographs

    • Document how the retina looks and help track changes over time

Medical and Family History

Your eye care provider will also:

  • Record a detailed family eye history
  • Ask about other medical problems that might suggest a syndrome involving RP (for example, hearing loss, kidney disease, or developmental issues)

Sometimes a broader medical examination is needed because, in some people, RP is part of a larger condition such as:

  • Usher syndrome (RP plus hearing loss)
  • Bardet–Biedl syndrome (BBS)
  • Refsum disease
  • Alport syndrome

Other Eye Complications Linked to RP

People with RP have a higher risk of developing additional eye problems, including:

  • Macular edema (swelling in the central retina)
    • Can blur or reduce central vision
  • Cataracts
    • Clouding of the eye’s lens
    • Common with aging and may appear earlier in people with RP

Regular eye checks with a Grand Rapids ophthalmologist are important to detect and treat these conditions early.

How Is Retinitis Pigmentosa Inherited?

RP is caused by changes (mutations) in genes that are important for retinal function. More than 300 genes have been linked to inherited retinal diseases.

Identifying the specific gene can:

  • Clarify the inheritance pattern
  • Help estimate the risk to children and other relatives
  • Determine if you may qualify for gene‑specific clinical trials or treatments

Main Inheritance Patterns

  1. Autosomal Recessive (AR)

    • Affects men and women equally
    • Often no obvious family history
    • Both parents are healthy but carry one copy of the RP gene
    • Each pregnancy has a 25% (1 in 4) chance of a child having RP
    • Risk is higher if parents are related (e.g., cousins)

  2. Autosomal Dominant (AD)

    • Only one parent needs to carry the gene
    • That parent may or may not have symptoms
    • Each child has a 50% (1 in 2) chance of inheriting the gene and developing RP

  3. X‑Linked Recessive (XL)

    • Primarily affects males
    • Females usually carry the gene and may have mild or no symptoms
    • The RP gene is carried on the X chromosome
    • Mother carriers: each son has a 50% chance of having RP; each daughter has a 50% chance of being a carrier
    • Affected males pass the gene to all daughters (carriers) and no sons

  4. Mitochondrial Inheritance

    • Caused by genetic changes in mitochondrial DNA (the “powerhouses” of cells)
    • Mitochondrial DNA is passed only from mothers to children

Genetic Testing and Genetic Counseling in Grand Rapids

What Is Genetic Testing?

Genetic testing for RP typically involves:

  • A blood sample or
  • A saliva sample

sent to a specialized laboratory to look for mutations in genes known to cause RP and other inherited retinal diseases.

Why Consider Genetic Testing?

Genetic testing can help:

  • Identify the specific gene causing RP (when possible)
  • Clarify the type and inheritance pattern of RP
  • Inform family planning decisions
  • Determine if you’re eligible for gene‑based treatments or clinical trials

However:

  • Not all RP genes are known yet
  • Testing does not always find the exact cause

Genetic Counseling

Genetic counseling is an essential part of the process. A genetic counselor or specialized ophthalmic genetics provider can help you:

  • Understand what the results mean for you and your family
  • Discuss risks for children and siblings
  • Explore emotional, practical, and ethical considerations

In the Grand Rapids area, your ophthalmologist can refer you to:

  • Clinical genetics services within Corewell Health or University of Michigan Health – West (Metro Health)
  • Dedicated genetic eye clinics in Michigan (often located at large academic centers)

Treatment and Research for Retinitis Pigmentosa

Currently, most forms of RP do not have a cure. Treatment focuses on:

  • Protecting remaining vision
  • Managing complications
  • Maximizing independence and quality of life

Gene‑Replacement Therapy

There is now a commercially available gene‑replacement treatment for a very rare inherited retinal disease caused by mutations in the RPE65 gene. This does not apply to all RP patients, but it shows what may be possible as research advances.

Ongoing Research

Promising areas of research include:

  • Gene therapy
  • Stem cell technology
  • Retinal implants and prosthetics
  • Clinical trials for specific genetic types of RP

If you live in the Grand Rapids area, your retina specialist can help you:

  • Determine if genetic testing is appropriate
  • Check for clinical trials in Michigan or nearby states
  • Coordinate care with larger research centers when needed

Managing Retinitis Pigmentosa in Daily Life

While RP is progressive, many people in Grand Rapids live full, active lives for many years with appropriate support and adjustments.

Lifestyle and Eye Health

  • Do not smoke
    • Smoking can damage blood vessels and may worsen eye disease
  • Eat a healthy diet
    • Emphasize fruits, vegetables, whole grains, lean protein, and omega‑3 fatty acids (e.g., fish)
  • Protect your eyes from UV light
    • Wear sunglasses and hats, especially around reflective surfaces like snow and water (common in West Michigan winters and near Lake Michigan)
