Causes & Risk Factors
Several factors can contribute to Retinal Pigment Epithelium Detachment.
The underlying mechanism of pigment epithelial detachment involves fluid accumulation beneath the retinal pigment epithelium layer.
The underlying mechanism of pigment epithelial detachment involves fluid accumulation beneath the retinal pigment epithelium layer. This separation most commonly occurs when the drainage system beneath the retina becomes compromised, typically due to age-related changes in Bruch's membrane. As we get older, this crucial membrane can thicken and develop deposits called drusen, which interfere with normal fluid flow and waste removal.
Age-related macular degeneration represents the primary cause, accounting for the vast majority of cases.
Age-related macular degeneration represents the primary cause, accounting for the vast majority of cases. In the dry form of macular degeneration, drusen deposits gradually accumulate and can cause the RPE to lift away from its normal position. The wet form involves abnormal blood vessel growth beneath the retina, which can leak fluid or blood and create larger, more dramatic detachments. These new blood vessels develop because the retinal tissue isn't getting adequate oxygen and nutrients.
Other causes include central serous chorioretinopathy, where fluid leaks from blood vessels in the choroid layer beneath the retina.
Other causes include central serous chorioretinopathy, where fluid leaks from blood vessels in the choroid layer beneath the retina. Inflammatory conditions, certain medications like corticosteroids, and rare genetic disorders can also trigger pigment epithelial detachments. High blood pressure and stress appear to play roles in some cases, particularly in central serous chorioretinopathy, which tends to affect younger adults compared to age-related macular degeneration.
Risk Factors
- Age over 50 years
- Family history of macular degeneration
- Smoking cigarettes or tobacco use
- High blood pressure
- Prolonged exposure to ultraviolet light
- Light-colored eyes (blue or green)
- Being female
- Caucasian ethnicity
- Diet low in antioxidants and omega-3 fatty acids
- Chronic stress or Type A personality
Diagnosis
How healthcare professionals diagnose Retinal Pigment Epithelium Detachment:
- 1
Diagnosing pigment epithelial detachment begins with a comprehensive eye examination that includes testing your visual acuity and examining the back of your eye with specialized instruments.
Diagnosing pigment epithelial detachment begins with a comprehensive eye examination that includes testing your visual acuity and examining the back of your eye with specialized instruments. Your eye doctor will dilate your pupils and use an ophthalmoscope or slit lamp to get a detailed view of your retina and macula. They may also have you look at an Amsler grid - a pattern of straight lines that can reveal visual distortions characteristic of macular problems.

Optical coherence tomography (OCT) has revolutionized the diagnosis and monitoring of pigment epithelial detachments.
Optical coherence tomography (OCT) has revolutionized the diagnosis and monitoring of pigment epithelial detachments. This painless imaging test uses light waves to create detailed cross-sectional pictures of your retina, clearly showing the separation between the RPE and underlying tissues. OCT can measure the height and extent of the detachment and help determine what type of material has accumulated beneath the RPE. Fluorescein angiography may also be performed, involving an injection of dye into your arm while photographs are taken of blood flow in your retina.

Your doctor will need to distinguish pigment epithelial detachment from other retinal conditions like retinal detachment, macular holes, or diabetic retinopathy.
Your doctor will need to distinguish pigment epithelial detachment from other retinal conditions like retinal detachment, macular holes, or diabetic retinopathy. The pattern of vision loss, appearance of the retina, and OCT findings help make this distinction. Additional tests might include fundus autofluorescence imaging, which can reveal metabolic changes in the RPE, or indocyanine green angiography for complex cases involving abnormal blood vessel growth.
Complications
- The primary concern with pigment epithelial detachment is progression to more advanced forms of macular degeneration that can cause significant vision loss.
- Large or persistent detachments may lead to permanent damage of the overlying photoreceptor cells, resulting in scotomas or blind spots in central vision.
- When associated with wet macular degeneration, untreated detachments can progress to disciform scarring, where fibrous tissue replaces normal retinal architecture and causes irreversible central vision loss.
- Rarely, very large pigment epithelial detachments can spontaneously rupture, causing sudden worsening of vision and often leading to rapid progression of macular degeneration.
- This complication, called a rip of the retinal pigment epithelium, typically occurs in detachments larger than 2-3 disc diameters and may be triggered by anti-VEGF treatment in susceptible cases.
- While this sounds alarming, modern monitoring techniques help identify high-risk detachments, and the benefits of treatment generally far outweigh the small risk of complications.
- Most people with pigment epithelial detachment maintain good functional vision with appropriate monitoring and treatment when needed.
Prevention
- While you cannot completely prevent age-related changes that lead to pigment epithelial detachment, several lifestyle modifications can significantly reduce your risk and slow progression.
- The most impactful step is avoiding tobacco use entirely, as smoking more than doubles the risk of developing macular degeneration.
- If you currently smoke, quitting at any age provides benefits, and your eye doctor can connect you with resources to help.
- Nutritional approaches play a crucial role in prevention.
- A diet rich in leafy green vegetables, colorful fruits, and omega-3 fatty acids from fish supports retinal health.
- The Age-Related Eye Disease Study found that specific supplements containing vitamins C and E, beta-carotene (or lutein for smokers), zinc, and copper can reduce the risk of advanced macular degeneration by about 25% in people with intermediate disease.
- Regular consumption of foods high in lutein and zeaxanthin, such as spinach, kale, and egg yolks, may provide additional protection.
- Protecting your eyes from ultraviolet light exposure and managing cardiovascular risk factors also contribute to prevention.
- Wearing sunglasses with 100% UV protection when outdoors, controlling blood pressure and cholesterol levels, maintaining a healthy weight, and exercising regularly all support overall eye health.
- For those with central serous chorioretinopathy risk factors, managing stress through relaxation techniques, adequate sleep, and avoiding unnecessary corticosteroid medications can help prevent recurrences.
Treatment approaches for pigment epithelial detachment depend largely on the underlying cause and whether abnormal blood vessel growth is present.
Treatment approaches for pigment epithelial detachment depend largely on the underlying cause and whether abnormal blood vessel growth is present. For detachments related to dry age-related macular degeneration without active leakage, careful monitoring is often the initial approach. Your eye doctor will schedule regular follow-up visits with OCT imaging to track any changes in the size or characteristics of the detachment. During this time, taking AREDS2 vitamins (a specific formulation of antioxidants and zinc) may help slow progression in people with intermediate to advanced dry macular degeneration.
When wet macular degeneration causes the detachment, anti-VEGF injections represent the primary treatment.
When wet macular degeneration causes the detachment, anti-VEGF injections represent the primary treatment. These medications, including bevacizumab, ranibizumab, and aflibercept, are injected directly into the eye to block the growth of abnormal blood vessels and reduce fluid leakage. The injection procedure is performed in the office under local anesthesia and typically needs to be repeated monthly or every few months depending on your response. Most people experience significant improvement in vision and reduction in detachment size with consistent anti-VEGF treatment.
For detachments caused by central serous chorioretinopathy, treatment may include laser therapy, photodynamic therapy, or anti-VEGF injections depending on the specific characteristics and duration of the condition.
For detachments caused by central serous chorioretinopathy, treatment may include laser therapy, photodynamic therapy, or anti-VEGF injections depending on the specific characteristics and duration of the condition. Laser treatment can seal leaking blood vessels, while photodynamic therapy uses a light-activated drug to target abnormal vessels. Managing underlying conditions like high blood pressure and avoiding medications that can worsen the condition, particularly corticosteroids, plays an important supporting role in treatment.
Emerging treatments show promise for various forms of pigment epithelial detachment.
Emerging treatments show promise for various forms of pigment epithelial detachment. Complement inhibitors are being studied for geographic atrophy, while gene therapy and stem cell treatments are in clinical trials for inherited retinal diseases. Sustained-release drug delivery systems may reduce the need for frequent injections in the future, and artificial intelligence is improving our ability to predict which detachments require immediate treatment versus continued monitoring.
Living With Retinal Pigment Epithelium Detachment
Adapting to life with pigment epithelial detachment often involves making small but meaningful changes to support your vision and overall well-being. Good lighting becomes especially important for reading and detailed tasks. Position reading materials and work areas near windows during the day, and use bright, direct lighting for evening activities. Many people find that LED desk lamps or reading lights significantly improve their ability to see fine details. Magnifying glasses, large-print books, and high-contrast materials can help maintain independence in daily activities.
