Reticular Pseudodrusen

Reticular pseudodrusen (often shortened to RPD) are tiny, grain-like deposits that sit above the retinal pigment epithelium (RPE) in the outer retina, in the zone where the light-sensing photoreceptors meet their support layer. Because of where they sit, doctors also call them subretinal drusenoid deposits (SDD). They look like small, yellow-white dots that tend to form a loose, net-like (reticular) pattern—most often just above the center of the retina (the superotemporal macula), an area rich in night-vision rods. RPD are strongly linked to age-related macular degeneration (AMD). Their presence means the eye is at higher risk of progressing to advanced AMD, especially the “dry” form with geographic atrophy, and they are also linked with a specific “wet” pattern (type 3 neovascularization/RAP). On modern scans (OCT), RPD are clearly seen on top of the RPE, which is different from classic soft drusen that collect below the RPE. EyeWikiPubMedPubMed Central

Reticular pseudodrusen (RPD) are tiny, pale, net-like spots that form in the light-sensing layer of the eye (the retina). Doctors also call them subretinal drusenoid deposits (SDD). Unlike ordinary drusen (which sit under the retinal pigment epithelium, or RPE), RPD sit above the RPE in the subretinal space and often appear in the outer retina where night-vision cells (rods) are common. On modern scans (OCT) they look like small mounds or deposits on top of the RPE, and on near-infrared images they create a reticular (net-like) pattern. RPD are strongly linked with age-related macular degeneration (AMD) and signal a higher risk of vision problems over time, especially difficulty with night vision and progression to late AMD. PubMed CentralLippincott Journals

RPD mean the retina is under stress. They are tied to thinning of the vascular layer under the retina (the choroid) and reduced blood flow. People with RPD often have slower dark adaptation—their eyes take longer to adjust to low light. Importantly, RPD are an independent risk factor for developing late AMD (both geographic atrophy and neovascular/wet AMD). PubMed Central+2PubMed Central+2MDPIAAO-HNS

Types

Doctors describe RPD in two helpful ways: by how they look across the retina, and by how they look in cross-section on OCT.

A) Appearance across the retina (multimodal imaging subtypes)

1. Dot RPD – look like many small dots that show up well on near-infrared images.

2. Ribbon RPD – look like faint, wavy, interconnected bands in the area around the fovea.

3. Peripheral RPD – less common; small globules seen a bit farther from the center.
   These “dot/ribbon/peripheral” patterns are simply different looks of the same process and can coexist. EyeWiki

B) Cross-section on OCT (structural stages)

1. Type 1 – thin granules sitting between the RPE and the photoreceptor line (ellipsoid zone) without lifting that line.

2. Type 2 – little mounds build up and gently push the photoreceptor line.

3. Type 3 – cone-shaped deposits poke up into the outer retina and interrupt the photoreceptor line.
   These OCT patterns confirm the above-RPE location that separates RPD from classic drusen. EyeWikiPubMed

Causes/risk

Important note: for RPD we mostly talk about contributors and risk mechanisms, not a single on/off cause. The items below summarize what research has linked to RPD; some are stronger links than others.

1. Aging of the outer retina – with age, photoreceptors and the RPE recycle lots of lipids; waste can accumulate above the RPE, helping deposits form. PubMed Central

2. Genetic risk (ARMS2/HTRA1) – common AMD risk variants, especially ARMS2, are associated with having RPD. PubMed Central

3. Genetic risk (CFH/complement pathway) – genes in the complement system (such as CFH) are linked to AMD and RPD biology in pathologic studies. PubMed Central

4. Complement-driven inflammation – histology shows complement components in subretinal deposits, suggesting immune involvement. ResearchGate

5. Lipid handling imbalance – the deposits contain cholesterol-rich debris; altered lipid transport above the RPE likely feeds deposit growth. PubMed Central

6. RPE stress/dysfunction – an overworked or stressed RPE may clear debris less efficiently, letting material build up in the subretinal space. PubMed Central

7. Rod vulnerability – RPD tend to cluster where rods are dense; rod function (especially dark adaptation) is often impaired, implying rod stress is part of the process. PubMed Central

8. Reduced choriocapillaris perfusion (vascular hypothesis) – several OCTA studies show impaired flow under RPD, although findings vary across methods and cohorts. NatureIOVSPubMed

9. Overall thinner or altered choroid – many (not all) studies report thinner choroid in eyes with RPD; the vascular bed beneath the retina may be compromised. PubMed Central

10. Smoking – a known AMD risk factor; cohorts with RPD often have higher smoking exposure, suggesting shared biology. PubMed Central

11. Systemic vascular risk – hypertension and cardiovascular disease have been explored alongside RPD as part of the AMD vascular story. PubMed Central

12. Oxidative stress – the outer retina has intense oxygen and light exposure; oxidative injury can damage membranes and promote deposit formation. PubMed Central

13. Female sex tendency – epidemiology shows RPD somewhat more often in women, although the reason is not fully clear. EyeWiki

14. Association with geographic atrophy – RPD often travel with GA and can signal faster atrophy spread; the atrophic environment may favor deposits. PubMed Central

15. Association with type 3 neovascularization (RAP) – RPD are enriched in eyes that develop this “retinal” form of NV; microvascular stress may connect them. EyeWiki

16. Sorsby macular dystrophy (link) – an inherited macular disease where RPD-like changes may appear as part of the phenotype. EyeWiki

17. Pseudoxanthoma elasticum (link) – a systemic elastic tissue disorder with retinal changes that can include RPD-like patterns. EyeWiki

18. Retinitis punctata albescens / fundus albipunctatus (links) – rare rod disorders reported with RPD-like spots in case descriptions. EyeWiki

19. Vitamin A deficiency (link) – severe deficiency affects rod health and has been reported alongside RPD patterns in some cases. EyeWiki

20. Diffuse macular stress state – newer functional work shows that in RPD, overall deposit burden (not just the spot you measure) ties to worse rod function, hinting at a wide, low-grade stress across the macula. PubMed Central

---

Symptoms

Many people with RPD feel nothing at first. Symptoms grow as photoreceptors struggle, especially in low light, or if AMD advances to atrophy or new vessels.

1. Trouble seeing in the dark (night vision problems) – dim places feel extra dim; it takes effort to get around. PubMed Central

2. Slow recovery after bright light (delayed dark adaptation) – after headlights or sunlight, vision “comes back” slowly. PubMed Central

3. Need for more light to read – you turn on brighter lamps to read comfortably.

4. Low-contrast blur – faint print, gray objects, smoke/fog scenes are harder to see.

5. Fluctuating clarity – good in bright, high-contrast settings; worse in dim rooms.

6. Glare sensitivity – bright lights scatter and feel harsh.

7. Mild central blur – letters look a bit washed or fuzzy on bad days.

8. Patchy dim spots near the center – small areas seem less clear, especially in low light.

9. Reading fatigue – more breaks are needed; print seems to fade quickly.

10. Color “dullness” – colors feel a bit less vivid in dim conditions.

11. Difficulty driving at night – headlights and dark roads are challenging.

12. Halos or streaks around lights – especially at night.

13. Wavy lines (metamorphopsia) – if fluid/new vessels develop, straight lines may look bent.

14. Missing letters or pieces of words – if atrophy expands, tiny gaps appear in the view.

15. One eye “lagging” the other – differences become noticeable when eyes are tested separately.

(Items 1–2 reflect the strongest functional signal reported in RPD—rod-mediated impairment and delayed dark adaptation.) PubMed Central

Diagnostic tests

Quick roadmap: We start with the simple chair-side checks, then move through targeted functional tests, a few lab/pathology items used mostly for context or research, standard electrophysiology, and finally the imaging tools that define RPD.

A) Physical exam

1) Dilated fundus exam with slit-lamp biomicroscopy
Your doctor looks through the pupil with a high-power lens. RPD can appear as subtle, pale dots in a loose net pattern, often above the macular center. Because they are faint, the exam can miss them—so imaging is nearly always added. EyeWiki

2) Indirect ophthalmoscopy (wider-field look)
A bright head-mounted light and a larger lens give a panoramic view to spot peripheral RPD patterns and survey for AMD changes. This complements the slit-lamp exam. EyeWiki

3) Best-corrected visual acuity (chart)
A basic baseline. Many people with RPD read well in standard room light; normal acuity does not rule out serious low-light dysfunction.

B) Manual/psychophysical functional tests

4) Amsler grid at home or in clinic
A simple square grid used to check for waviness or missing spots. It can hint at early fluid or atrophy if AMD advances.

5) Low-luminance visual acuity
Reading the chart through a neutral density filter simulates dim light. People with RPD often lose more lines under low light than expected for their bright-light acuity.

6) Contrast sensitivity (e.g., Pelli-Robson)
Measures how well faint gray letters can be seen. RPD can reduce contrast performance even when standard acuity looks good.

7) Dark adaptation testing
After a light bleach, a handheld device measures how quickly vision recovers in the dark. In RPD, this “recovery time” is often clearly delayed, showing rod stress. PubMed Central

C) Laboratory & pathological context

8) Histopathology (research or post-mortem correlation)
Microscopy has proven that RPD are above the RPE and contain lipid-rich, drusen-like debris; this discovery changed how we understand AMD biology on both sides of the RPE. PubMed CentralPubMed

9) Genetic testing (ARMS2/HTRA1, CFH and others)
Not routinely required, but studies show ARMS2 and overall genetic risk scores correlate with RPD—useful in research and sometimes in counseling. PubMed Central

10) Systemic risk labs (lipids, cardiovascular risk)
Ordered based on history, not to “diagnose” RPD; they help manage whole-body risk that travels with AMD in many people. PubMed Central

D) Electrodiagnostic tests

11) Full-field electroretinogram (ffERG)
An objective recording of rod and cone signals. In RPD, rod responses can be reduced or delayed, matching the dark-adaptation complaints. (Used selectively in clinics and more often in studies.) PubMed Central

12) Multifocal ERG (mfERG)
Maps cone-driven function across the macula. It can show small, local depressions that align with RPD-affected zones or nearby atrophy.

13) Electro-oculogram (EOG)
A global RPE function test. It is rarely needed, but abnormalities may support an outer-retina/RPE stress picture when the diagnosis is complex.

E) Imaging tests

14) Spectral-domain OCT (cross-sectional)
The core test. It shows RPD above the RPE as granular or mound-shaped bumps that can pierce the photoreceptor line (Type 1–3). OCT is how we separate RPD from classic drusen. EyeWikiPubMed

15) En face OCT
Builds a face-on map of the deposit layer so doctors can see the net-like spread and follow change over time.

16) OCT angiography (OCTA)
Looks at blood-flow maps without dye. Several studies show reduced choriocapillaris flow under RPD, while others—especially in specific AMD stages—find less or no difference. Your doctor interprets OCTA together with OCT and symptoms. NatureIOVSPubMed Central

17) Near-infrared reflectance (NIR) imaging
A fast, noninvasive photo that highlights RPD as dark spots against a bright background; extremely useful for detection. EyeWiki

18) Fundus autofluorescence (FAF)
Shows a “salt-and-pepper” pattern—many small low autofluorescence dots with thin bright lines in between—helpful for mapping the field at risk. EyeWiki

19) Color fundus photography (including blue-channel)
Basic documentation; plain color photos often miss RPD, but the blue channel can help. Still, it is less sensitive than NIR/FAF/OCT. EyeWiki

20) Indocyanine green angiography (ICGA)
A dye test that can show RPD as areas of reduced fluorescence in mid-to-late phases; used when other diseases are in the mix or when planning treatment in complex AMD. EyeWiki

Non-pharmacological treatments

There is no direct cure for RPD. These steps aim to protect retinal health, slow AMD progression, and keep you functioning well.

1. Understand your condition. Learn what RPD are, how they differ from classic drusen, and why regular follow-up matters. Informed patients recognize changes earlier and seek timely care. PubMed Central

2. Stop smoking completely. Smoking increases oxidative stress and AMD risk. Quitting lowers the chance of progression. Mechanism: reduces toxic free radicals and improves blood and oxygen supply to the retina.

3. Protect your eyes from bright sunlight. Wear UV-blocking sunglasses and a brimmed hat. Mechanism: limits cumulative light-related oxidative stress on photoreceptors and RPE.

4. Follow an AMD-friendly diet. Eat leafy greens (lutein/zeaxanthin), colorful vegetables, and fish rich in omega-3s; limit ultra-processed foods. Mechanism: antioxidants and macular pigments help filter blue light and counter oxidative injury. National Eye Institute

5. Keep blood pressure, lipids, and blood sugar well controlled. Healthy vessels support the choroid and retina. Mechanism: reduces ischemia and microvascular damage linked to AMD changes.

6. Exercise regularly (most days). Moderate activity improves cardiovascular health and retinal perfusion; it also reduces inflammation and oxidative stress.

7. Address sleep-disordered breathing (possible nocturnal hypoxia). If you snore or feel excessively sleepy, ask about screening for obstructive sleep apnea (OSA). Some studies link OSA-related hypoxia with AMD and RPD subtypes; managing OSA may help overall retinal health. Mechanism: improves nighttime oxygen levels for rod-rich retina. PubMed CentralPubMed

8. Optimize home lighting. Use bright, even, non-glare lighting and task lights for reading. Mechanism: reduces strain on impaired rod function and improves safety at night.

9. Night-driving strategies. Limit night driving if glare and adaptation are poor; clean windshields and use anti-glare lenses. Mechanism: compensates for delayed dark adaptation common with RPD. AAO Journal

10. Low-vision aids and training (when needed). Handheld magnifiers, electronic magnifiers, high-contrast apps, and orientation training maintain independence if central vision drops. Mechanism: enhances remaining vision and reading speed.

11. Use an Amsler grid or smartphone vision-check apps weekly. Mechanism: self-monitoring helps detect new distortion or scotomas that may signal conversion to wet AMD.

12. Regular dilated eye exams with OCT/FAF/NIR imaging. Mechanism: early detection of neovascular AMD or atrophy allows prompt treatment. PubMed Central

13. Blue-light hygiene on screens. Use comfort settings (night mode) and take breaks. Mechanism: reduces perceived glare and visual fatigue; evidence for disease modification is limited but comfort improves compliance.

14. Nutrition counseling. A clinician can tailor diet around AREDS2 principles, allergies, or drug–nutrient interactions. National Eye Institute

15. Fall-prevention at home. Improve contrast (colored tape on steps), remove tripping hazards, and ensure adequate lighting to prevent injuries from low-light vision.

16. Manage cardiovascular risk comprehensively. Work with your primary care doctor on cholesterol, triglycerides, weight, and exercise; RPD has been associated with systemic vascular disease in some studies. Mechanism: supports choroidal circulation. NatureBMJ Open

17. Stress management and sleep quality. Good sleep and lower stress may reduce systemic inflammation that can affect retinal health.

18. Avoid smoking exposure (second-hand). Mechanism similar to #2; protects against oxidative stress.

19. Vaccination & general health maintenance. Staying healthy (e.g., flu shots) prevents systemic illnesses that can exacerbate ocular inflammation or vascular stress.

20. Join support communities. Peer support improves adherence to follow-up, protective diet, and home adaptations.

Regenerative/immune-modulating therapies

There are no approved “hard immunity booster” drugs for RPD. These options are either approved for GA or wet AMD, or are in the research realm for photoreceptor/RPE rescue.

1. Pegcetacoplan (C3 inhibitor) – approved for GA. Dose: 15 mg intravitreal monthly or every other month. Function: slows GA expansion; Mechanism: dampens complement over-activation. Not specific to RPD but relevant when GA coexists. AHDB Online

2. Avacincaptad pegol (C5 inhibitor) – approved for GA. Dose: 2 mg intravitreal monthly. Function/Mechanism: blocks terminal complement to slow GA growth. Label updates in 2025 provided additional guidance; your specialist will individualize. FDA Access DataAstellas Pharma US, Inc. | News Room

3. RPE stem-cell therapies (clinical trials). Dose: surgical implantation of human embryonic stem cell- or iPSC-derived RPE (sheet or suspension). Function: aims to replace damaged RPE and support photoreceptors. Mechanism: cellular replacement and trophic support. Investigational; for advanced atrophy, not for isolated RPD.

4. Neuroprotective agents (e.g., brimonidine DDS, risuteganib) – investigational. Dose: varies by trial. Function: protect photoreceptors from oxidative/inflammatory injury. Mechanism: anti-apoptotic/anti-inflammatory signaling. Not approved for AMD as of now.

5. Photobiomodulation (device-based, investigational). Dose: scheduled light sessions. Function: may boost mitochondrial function; Mechanism: cytochrome-c-oxidase activation and reduced oxidative stress. Data are mixed; talk to your specialist before pursuing.

Procedures/surgeries

No surgery removes RPD. These procedures treat complications or coexisting issues.

1. Intravitreal injection procedure (office-based).
   What it is: A quick, sterile injection of medicines (anti-VEGF or complement inhibitors) into the eye.
   Why it’s done: To control wet AMD or slow GA growth.
   Mechanism: Delivers the drug where it works—inside the eye. FDA Access Data+1

2. Photodynamic therapy (PDT) with verteporfin (select cases).
   What it is: Light-activated drug treatment that seals abnormal vessels.
   Why it’s done: Rarely used now for typical wet AMD but may be used in polypoidal choroidal vasculopathy or non-responders.

3. Cataract surgery (phacoemulsification with IOL).
   What it is: Removal of a cloudy lens.
   Why it’s done: Improves clarity and contrast when cataract coexists, helping overall function in AMD patients; it doesn’t treat RPD directly.

4. Pars plana vitrectomy for complications.
   What it is: Microsurgery to remove vitreous gel/blood.
   Why it’s done: For dense, non-clearing vitreous hemorrhage or traction from neovascular complications, to restore media clarity and allow further treatment.

5. Submacular hemorrhage displacement (gas ± tPA).
   What it is: Intravitreal gas (and sometimes tissue plasminogen activator) to move blood away from the fovea.
   Why it’s done: To limit photoreceptor toxicity after a large bleed from wet AMD.

Prevention tips

1. Don’t smoke; avoid second-hand smoke.

2. Eat an AREDS2-friendly diet: leafy greens, colorful vegetables, fish; limit refined carbs. National Eye Institute

3. Talk to your doctor about AREDS2 supplements if you have intermediate AMD. National Eye Institute

4. Control blood pressure, cholesterol, weight, and blood sugar.

5. Exercise most days.

6. Use UV-blocking sunglasses and a hat outdoors.

7. Optimize indoor lighting and reduce glare.

8. Get regular eye exams with OCT and imaging to monitor RPD. PubMed Central

9. Consider evaluation for sleep apnea if you have symptoms (snoring, daytime sleepiness). PubMed Central

10. Keep a home Amsler grid and check weekly; call promptly for new distortion or dark spots.

---

When to see a doctor urgently vs routinely

• Call urgently (same day or ASAP) if you notice sudden distortion of straight lines, a new gray/black spot, a drop in central vision, flashing lights, or a curtain of vision loss. These can signal conversion to wet AMD or other urgent eye diseases that need treatment quickly.

• Schedule routine visits every 3–12 months (interval based on your doctor’s advice) for dilated exams and OCT/other imaging to monitor RPD, detect early changes, and review risk-reduction steps. PubMed Central

---

What to eat and what to avoid

1. Eat dark leafy greens daily (spinach, kale) for lutein/zeaxanthin.

2. Eat colorful fruits/veggies (peppers, oranges, berries) for antioxidants.

3. Eat oily fish 2–3 times/week (salmon, sardines) for omega-3s.

4. Include eggs (yolk contains lutein/zeaxanthin) if diet allows.

5. Choose whole grains and legumes; limit refined sugars to avoid glycemic spikes.

6. Use olive oil and nuts for healthy fats.

7. Hydrate well; dehydration worsens fatigue and visual comfort.

8. Avoid smoking and heavy alcohol; both increase oxidative stress.

9. Limit ultra-processed foods and trans fats.

10. Discuss AREDS2 supplements with your clinician if you have intermediate AMD; avoid beta-carotene if you smoke. National Eye Institute

FAQs

1) Is RPD the same as drusen?
No. Ordinary drusen sit under the RPE; RPD sit above the RPE in the subretinal space and often form a net-like pattern. PubMed Central

2) Does RPD always mean I will get severe vision loss?
Not always. But RPD raises the risk of late AMD, so close monitoring and risk-reduction steps are important. PubMed Central

3) Why is my night vision worse?
RPD commonly affect rod-rich areas; many patients have delayed dark adaptation, so low-light tasks feel harder. AAO Journal

4) Can diet really help?
For people with intermediate AMD, the AREDS2 formula can slow progression, and a plant-forward, fish-rich diet supports eye health. National Eye Institute

5) Should I take beta-carotene?
No—AREDS2 removed beta-carotene, especially due to lung cancer risk in smokers. Use lutein/zeaxanthin instead. National Eye Institute

6) Are omega-3 pills necessary?
They were not beneficial as an add-on in AREDS2, but eating fish is still healthy. National Eye Institute

7) How often should I be checked?
Your retina specialist will decide, but many patients are seen every 3–12 months, sooner if symptoms change. PubMed Central

8) Can RPD go away?
RPD can wax and wane, but they usually indicate ongoing retinal stress; the focus is on monitoring and preventing progression. PubMed Central

9) Do blue-light-blocking glasses stop RPD?
Evidence is limited for disease modification. Use whatever improves comfort and reduces glare while focusing on proven measures like AREDS2, smoking cessation, and systemic health. National Eye Institute

10) Is there a link with heart or blood vessel disease?
Several studies report associations between RPD and cardiovascular disease; this does not prove causation, but it supports careful systemic health management. NatureBMJ Open

11) What about sleep apnea?
Research suggests nocturnal hypoxia may relate to AMD and RPD; if you have symptoms, ask about testing. Treating OSA benefits overall health and may help eye health indirectly. PubMed Central

12) Are there shots to prevent vision loss?
If you develop wet AMD, anti-VEGF injections can protect and often improve vision. For GA, complement inhibitors can slow area growth. FDA Access Data+1AHDB Online

13) Do injections cure AMD or RPD?
No. They control complications or slow GA growth. Ongoing monitoring and injections are usually needed. FDA Access DataAHDB Online

14) Are stem-cell therapies available now?
Only in clinical trials for advanced atrophy; talk to your specialist about eligibility and risks.

15) What’s the single most impactful habit I can change today?
If you smoke, quit. Then build an AREDS2-friendly diet and keep regular eye appointments. National Eye Institute
