Central Cloudy Dystrophy of François

Central cloudy dystrophy of François (often shortened to CCDF) is a very rare corneal condition where the clear window of the eye (the cornea) develops faint, gray, cloudy “mosaic-like” spots in the central area. These cloudy areas are usually polygon (many-sided) or rounded, and they are separated by thin, clearer lines, so the cornea can look like a cracked-ice or crocodile-skin pattern when the eye is examined with a slit-lamp microscope. EyeWiki+2Orpha+2

Central cloudy corneal dystrophy of François (CCDF) is a very rare corneal stromal dystrophy. It usually shows polygon/rounded cloudy areas deep in the cornea with clear spaces between them, and it usually does not harm vision. Most people find out they have it during a routine slit-lamp exam because it is often non-progressive and asymptomatic. NCBI+3Orpha+3EyeWiki+3

Because CCDF is usually mild, there is no medicine that “cures” or removes the dystrophy. Care is mostly about keeping the eye comfortable, treating dry eye or surface irritation, and using procedures only if vision becomes affected for another reason. EyeWiki+2PMC+2

In CCDF, the cloudy pattern is mainly found deep in the cornea’s stroma (the thick middle layer), often close to the back surface of the cornea. It is usually in both eyes, often looks similar in both eyes, and in many people it does not reduce vision or cause major problems. Genetic Diseases Info Center+2WebEye+2

Doctors still debate whether CCDF is always a true “inherited dystrophy” or sometimes a degenerative look-alike (a change that can happen with age). Some families have been reported with multiple affected members (suggesting inheritance), but many cases appear sporadic (no clear family pattern). EyeWiki+2PubMed+2

Other names

CCDF is also called central cloudy corneal dystrophy of François (same meaning, longer name). Orpha+2Genetic Diseases Info Center+2

Some books and summaries also use François dystrophy or François disease to describe the same central cloudy mosaic pattern in the cornea. SpringerLink+1

Types

CCDF does not have widely accepted “official types” like many other diseases, but doctors often describe patterns based on how it appears in real patients and reports. PMC+1

1. Sporadic (non-familial) pattern: Many people diagnosed with CCDF have no relatives with the same finding, which supports the idea that at least some cases may be non-inherited. EyeWiki+1

2. Familial (reported inherited) pattern: Some older and modern case reports describe families where several members have a similar central cloudy mosaic, which has been interpreted as possibly autosomal dominant in those families. PubMed+2Moran CORE+2

3. “Phenocopy” / degenerative look-alike pattern: Major classification discussions note that CCDF can look clinically indistinguishable from posterior crocodile shagreen, which is usually considered an age-related degeneration, not a classic inherited dystrophy. PMC+2SciSpace+2

4. Isolated CCDF vs CCDF with coexisting eye findings: Some patients have CCDF plus other common eye problems (for example cataract, early Fuchs findings, or keratoconus features), and symptoms may come mainly from the coexisting condition, not from CCDF itself. WebEye+1

Causes

The exact cause of CCDF is unknown. That means science has not proven one single reason that explains all cases. EyeWiki+2PMC+2

So, when clinicians write “causes” for CCDF, they often mean (A) suspected contributors / risk patterns and (B) conditions that can cause a similar central cloudy cornea and must be ruled out. The list below is written in that practical, real-clinic way (because CCDF itself has no confirmed single cause). EyeWiki+2PMC+2

1. Sporadic (unknown) change: Many cases happen with no family history and no clear trigger, meaning the cloudy mosaic may appear as an unexplained corneal finding discovered during an eye exam. EyeWiki+1

2. Familial tendency (possible inherited form): In some families, several relatives show similar central deep stromal clouding, suggesting a genetic pattern in those specific families, even though this is not proven for all patients. PubMed+1

3. Posterior crocodile shagreen (degenerative): This is an age-related mosaic pattern in the deep cornea that can look very similar; some experts think some “CCDF” cases may actually be this degeneration. PMC+2EyeWiki+2

4. Anterior crocodile shagreen: Another crocodile-like pattern that may be seen in different corneal layers; it is usually discussed as a differential diagnosis when a mosaic pattern is noticed. EyeWiki+1

5. Arcus senilis / lipid arcus (usually peripheral): Fatty lipid rings typically form at the corneal edge with age, not the center, but they are mentioned because they can coexist with other corneal “aging” changes and can confuse the overall appearance. JAMA Network+1

6. Fleck corneal dystrophy: This causes small scattered spots in the cornea and can be mistaken for other stromal patterns unless the doctor carefully checks the exact shape, depth, and distribution. Ophthalmobytes+1

7. Pre-Descemet corneal dystrophy: This involves fine changes near the back of the cornea (close to Descemet’s membrane) and is often considered when deep stromal haze is seen. Ophthalmobytes+1

8. Posterior amorphous corneal dystrophy (PACD): PACD can create gray-white sheet-like stromal opacities and is commonly compared with CCDF in clinical reviews because both tend to be mild and may not progress fast. Modern Optometry+1

9. Congenital stromal corneal dystrophy: Some stromal dystrophies start very early in life and can cloud the cornea; doctors separate them from CCDF by history, exam pattern, and sometimes genetics. Ophthalmobytes+1

10. Macular corneal dystrophy: This stromal dystrophy can cause corneal haze and reduced vision; it is important to rule out because it is more visually significant than CCDF and has different deposits and course. Ijo+1

11. Granular corneal dystrophy: This causes gray-white deposits in the stroma (often clearer “granules”) and can be separated from CCDF by the deposit shape, depth, and family history patterns. Ijo+1

12. Lattice corneal dystrophy: This can make branching lines in the cornea and may cause symptoms; it is listed because stromal dystrophies can overlap in “cloudy cornea” complaints until the slit-lamp pattern is clear. Ijo+1

13. Schnyder corneal dystrophy: This involves cholesterol/lipid deposition and can cause corneal clouding; it is a key “rule-out” diagnosis when central stromal opacity is noticed. RBO Journal+1

14. Ichthyosis-related corneal clouding: Some skin disorders (like ichthyosis) can be linked with cloudy corneas; experts mention this because it can mimic corneal haze patterns and should be checked by history and skin exam. JAMA Network

15. Past corneal inflammation (old keratitis): Infections or inflammation can leave stromal scars or haze that may look cloudy; history of redness, pain, or ulcers helps doctors separate scars from CCDF. National Eye Institute+1

16. Past eye injury (trauma): Trauma can disturb corneal collagen and leave long-term haze; unlike CCDF, trauma haze often matches the injury location and may be one-sided. National Eye Institute+1

17. Corneal surgery haze (for example after keratoplasty or refractive surgery): Surgery can change corneal clarity, and sometimes CCDF is discovered incidentally when a person is being evaluated for another eye surgery. JAMA Network+1

18. Keratoconus with central scarring: Keratoconus changes corneal shape and can lead to central haze/scar in some people; imaging tests help separate shape disease from true stromal mosaic patterns. WebEye+1

19. Metabolic storage diseases (example: mucopolysaccharidosis): Some body-wide storage disorders can cloud the cornea; they are important to consider especially if there are systemic symptoms, even though CCDF itself is usually mild. JAMA Network+1

20. Medication or toxic deposits (rare corneal deposits): Some drugs and exposures can cause corneal deposits or haze; doctors use history plus slit-lamp appearance to decide if deposits explain the clouding. National Eye Institute+1

Symptoms

Many people with CCDF have no symptoms, and the finding is noticed only during an eye exam. Genetic Diseases Info Center+2EyeWiki+2

Below are possible symptoms someone might report; when symptoms exist, they may come from another eye problem occurring at the same time (like dry eye, cataract, or another corneal disease), not from CCDF alone. WebEye+2National Eye Institute+2

1. No symptoms at all: This is the most common “symptom,” meaning the person feels normal and sees well, and the doctor finds CCDF during routine slit-lamp examination. Genetic Diseases Info Center+1

2. Mild blur (especially in haze complaints): Some patients describe hazy vision, but this can be due to cataract or other corneal changes; CCDF is often reported to have little effect on vision by itself. WebEye+2Genetic Diseases Info Center+2

3. Glare in bright light: Any corneal irregularity or haze can scatter light and increase glare; the eye exam helps decide if CCDF is actually the reason or if another problem is present. National Eye Institute+2Cleveland Clinic+2

4. Halos around lights at night: Halos are common with many corneal and lens problems; doctors consider CCDF among other causes only after careful exam of the cornea and lens. Cleveland Clinic+1

5. Mild “foggy” feeling: People sometimes describe a “film” or “fog,” which may come from dry eye or surface issues rather than deep stromal findings like CCDF. Cleveland Clinic+1

6. Slow change noticed over years: CCDF is often described as non-progressive or very slowly changing; if vision declines quickly, doctors usually look for another cause. Modern Optometry+2PMC+2

7. Light sensitivity (photophobia): Photophobia is not a classic CCDF feature, but it can happen with surface irritation or other corneal disease that may coexist with CCDF. National Eye Institute+2Cleveland Clinic+2

8. Eye dryness or burning: Dry eye is extremely common and can blur vision and cause discomfort, and it may be the real reason someone seeks care when CCDF is found incidentally. Cleveland Clinic+1

9. Foreign-body sensation (“something in the eye”): Deep stromal dystrophies usually do not cause this directly, but surface disease can, so clinicians separate surface symptoms from deep stromal patterns. Cleveland Clinic+1

10. Fluctuating vision: Vision that changes during the day often suggests tear-film issues or refractive instability rather than a stable deep stromal mosaic pattern. Cleveland Clinic+1

11. Mild reduction in contrast (colors look dull): Light scatter can reduce contrast; doctors check whether the cornea, lens, or retina is responsible. National Eye Institute+1

12. Double vision in one eye (monocular ghosting): Corneal shape problems like keratoconus can cause ghosting; this symptom prompts corneal topography/tomography to look for shape disease. PMC+1

13. Need for stronger glasses over time: Changes in refraction are common with aging and other corneal disorders; CCDF itself is often stable, so refraction changes push the doctor to look for other causes. Cleveland Clinic+2National Eye Institute+2

14. Reduced best-corrected vision (rare for isolated CCDF): If even the best glasses cannot restore clear vision, clinicians consider other corneal dystrophies, scars, cataract, or retinal disease. Modern Optometry+2National Eye Institute+2

15. Symptoms from coexisting disease (example: cataract haze after surgery): Some reported patients were evaluated because of haze that did not improve after cataract surgery, and CCDF was identified as a corneal finding during that work-up. WebEye+1

Diagnostic tests

CCDF is diagnosed mainly by a careful eye exam, especially slit-lamp examination, and imaging can help confirm the depth and pattern of the stromal changes and rule out look-alikes. National Eye Institute+2Cleveland Clinic+2

Physical exam

1. Slit-lamp biomicroscopy (main test): The doctor uses a bright “thin sheet” of light and high magnification to see the cornea layers. CCDF shows a central mosaic of gray-white polygonal opacities with clearer lines between them, usually deep in the stroma. National Eye Institute+2EyeWiki+2

2. Specular reflection at the slit lamp (endothelium look): Using a reflection technique, the clinician checks the back corneal surface for signs of endothelial disease (like Fuchs) because those can also affect clarity and may coexist. WebEye+1

3. Dilated eye examination: Dilating drops let the doctor examine the lens and retina to make sure blur or haze symptoms are not caused by cataract or retinal disease instead of the cornea. National Eye Institute+1

4. Intraocular pressure (IOP) measurement: Some older family reports noted glaucoma in affected families, so checking eye pressure and optic nerve health is part of a complete evaluation. PubMed+1

Manual tests 

5. Visual acuity test (distance and near): This measures how clearly you see letters. Many CCDF patients have normal acuity, so reduced acuity makes the clinician search for another cause or an additional diagnosis. Genetic Diseases Info Center+1

6. Refraction (glasses test): The “which is better, 1 or 2?” test shows whether blur improves with lenses. If refraction does not fix blur well, corneal haze, corneal shape disease, or other pathology is considered. Cleveland Clinic+1

7. Glare testing / contrast testing (simple functional checks): These tests evaluate how scattered light affects vision. They help document functional impact, because CCDF is often mild and may not explain severe glare by itself. Modern Optometry+2National Eye Institute+2

8. Corneal sensitivity test: A gentle touch (or special filament) checks corneal nerve sensation. This helps rule out neurotrophic problems that can change corneal health and clarity, especially if the surface is abnormal. National Eye Institute+1

Lab and pathological tests

9. Family history assessment (clinical “genetic” screen): Asking about relatives with similar findings helps separate suspected familial CCDF from sporadic cases and from degenerations that happen with age. EyeWiki+2PubMed+2

10. Genetic testing (selective, usually for differentials): CCDF itself has no single confirmed gene in many modern classifications, but genetic testing may be ordered when the pattern might actually be another inherited stromal dystrophy. PMC+1

11. Corneal histopathology (when tissue is available): If a corneal transplant is done for another reason, the removed cornea can be stained and studied; reports have described stromal material that stains like acid mucopolysaccharide in CCDF-labeled cases. JAMA Network+1

12. Electron microscopy (research/special cases): Very high-magnification studies have described extracellular vacuoles and fibrillogranular material in reported CCDF specimens, which can help understand what the cloudy areas contain. JAMA Network+1

Electrodiagnostic tests

13. Visual evoked potential (VEP): VEP checks how well signals travel from the eye to the brain. It is not a CCDF-specific test, but it helps if vision loss seems worse than corneal findings suggest. National Eye Institute+1

14. Electroretinography (ERG): ERG measures retina function. It helps rule out retinal disease when symptoms do not match the mild corneal pattern typical of CCDF. National Eye Institute+1

15. Electro-oculography (EOG): EOG can help evaluate certain retinal pigment epithelium problems; it is used selectively when the clinician suspects a retinal explanation for symptoms rather than a corneal one. National Eye Institute+1

Imaging tests

16. In vivo confocal microscopy (IVCM): This imaging can “zoom in” on corneal micro-structure while the eye is alive. In CCDF, studies describe abnormal stromal deposits and dark striae that help separate CCDF from other stromal disorders. PubMed+2JAMA Network+2

17. Anterior segment OCT (AS-OCT): AS-OCT provides cross-section images of the cornea and can show where the opacity sits within corneal layers; it is used to evaluate corneal dystrophies and subtle corneal pathology. PubMed+2MDPI+2

18. Corneal topography: This maps the front corneal surface shape. It is useful if keratoconus or irregular astigmatism is suspected, especially when symptoms like ghosting are present. PMC+2Annals of Eye Science+2

19. Corneal tomography: Tomography measures both anterior and posterior corneal shape and thickness in 3D. It helps detect early ectasia and separates “shape problems” from “deposit/haze problems.” PMC+1

20. Pachymetry (corneal thickness measurement): Measuring thickness helps document corneal health and supports differential diagnosis, because some stromal dystrophies and degenerations can be associated with different thickness patterns. PMC+1

Non-Pharmacological Treatments

1. Observation (watching and follow-up): Most CCDF needs no active treatment. The purpose is to confirm the diagnosis, record photos, and watch for any other corneal problem. Mechanism: regular slit-lamp checks help doctors notice changes early (even though CCDF usually does not progress). EyeWiki+1

2. Accurate glasses/vision correction: If vision is blurry, it is often from refractive error (nearsightedness/astigmatism), not CCDF itself. Purpose: make vision clear. Mechanism: lenses bend light correctly onto the retina. EyeWiki+1

3. Anti-glare and UV-blocking sunglasses: Purpose: reduce glare and light sensitivity and protect the ocular surface from bright sunlight. Mechanism: filters lower scattered light and UV exposure that can worsen surface dryness and discomfort. National Eye Institute

4. Blink training + screen breaks: Long screen time reduces blinking and dries the corneal surface. Purpose: keep the tear film stable. Mechanism: more complete blinking spreads tears evenly and reduces dry spots. TFOS DeWS Report+1

5. Room humidity control (humidifier, reduce direct fan/AC to face): Dry air can worsen irritation even when CCDF itself is quiet. Purpose: improve comfort. Mechanism: higher humidity slows tear evaporation. TFOS DeWS Report+1

6. Warm compress and eyelid hygiene (if meibomian gland problems): Purpose: improve the oily tear layer so tears last longer. Mechanism: warmth melts thick oil and gentle cleaning reduces lid inflammation that can drive dry eye symptoms. TFOS DeWS Report+2PubMed+2

7. Avoid eye rubbing and protect from trauma: Purpose: prevent surface scratches and irritation. Mechanism: rubbing can damage the corneal epithelium and trigger pain/erosions in vulnerable eyes. EyeWiki

8. Night eye protection (shield or moisture goggles): Purpose: reduce overnight drying and accidental rubbing. Mechanism: a physical barrier and moist environment helps the corneal surface stay hydrated during sleep. TFOS DeWS Report+1

9. Scleral contact lenses (specialty lenses): Purpose: improve vision and comfort in irregular corneas or severe dryness. Mechanism: the lens vaults over the cornea and holds a fluid layer, smoothing the optical surface and protecting the epithelium. EyeWiki+2PMC+2

10. PROSE device (advanced scleral system): Purpose: protect the ocular surface and improve vision when standard lenses fail. Mechanism: creates a stable fluid reservoir and a smooth refractive surface over the cornea. EyeWiki

11. Rigid gas-permeable lenses (selected cases): Purpose: sharper vision if corneal surface irregularity is present. Mechanism: a rigid lens masks corneal shape issues by creating a smooth front surface for light focusing. EyeWiki

12. Bandage contact lens (short-term, doctor supervised): Purpose: reduce pain and help healing if there is a surface defect or erosion. Mechanism: the lens covers exposed nerve endings and acts like a “bandage” while epithelium repairs. American Academy of Ophthalmology+2EyeWiki+2

13. Punctal plugs (tear-duct plugs): Purpose: keep natural tears on the eye longer for dry eye symptoms. Mechanism: blocks drainage through puncta so the tear film stays longer on the cornea. AAO Journal+1

14. Treat associated dry eye step-by-step (DEWS approach): Purpose: match treatment strength to symptom severity. Mechanism: starts with education/environment, then adds stronger options if needed, to restore tear homeostasis. TFOS DeWS Report+1

15. Manage blepharitis/allergy triggers (dust, smoke, cosmetics irritants): Purpose: reduce lid and surface inflammation that can worsen discomfort. Mechanism: removing triggers lowers inflammatory signals that destabilize the tear film. TFOS DeWS Report+1

16. Hydration and sleep routine: Purpose: support natural tear production and healing. Mechanism: dehydration and poor sleep can worsen dry eye symptoms and ocular discomfort. World Health Organization+1

17. Low-vision aids (rare, if vision reduced for other reasons): Purpose: help reading and daily tasks. Mechanism: magnification and contrast tools make images larger and clearer for the brain. Orpha+1

18. Genetic counseling / family eye checks (when family clustering is suspected): Purpose: clarify inheritance questions and guide family screening. Mechanism: understanding family history supports early detection of other corneal disorders. Cornea Society+1

19. Careful planning before refractive surgery (if ever considered): Purpose: avoid surprises and choose safe candidates. Mechanism: detailed corneal mapping and surgeon judgment reduce risk; a case report described LASIK without CCDF worsening, but this is not a rule for everyone. EyeWiki+1

20. Regular eye-health habits (exercise, control diabetes/BP if present): Purpose: protect long-term eye health. Mechanism: good general health lowers risk of other eye diseases that could reduce vision. National Eye Institute+1

When to See Doctors

See an ophthalmologist urgently if you have new pain, strong light sensitivity, sudden redness, discharge, a white spot on the cornea, or sudden drop in vision, because these may be infection, erosion, or inflammation—not “just CCDF.” EyeWiki+1

Also book a visit if you have chronic dryness, gritty feeling, frequent watering, or blurred vision that comes and goes, because treatable dry eye disease is common and can be managed step-by-step. American Academy of Ophthalmology+1

What to Eat and What to Avoid

1. Eat: dark leafy greens (spinach, kale). Why: carotenoids and general eye nutrition support. National Eye Institute+1

2. Eat: fish rich in omega-3 (if your diet allows). Why: supports tear and inflammation balance. National Eye Institute+1

3. Eat: colorful fruits/vegetables daily. Why: antioxidants support tissue health. World Health Organization+1

4. Eat: eggs and nuts in moderation. Why: helpful nutrients like lutein and healthy fats. American Academy of Ophthalmology+1

5. Eat: enough protein (fish/beans/lentils/chicken). Why: supports healing and body repair. World Health Organization

6. Avoid/limit: ultra-processed foods high in sugar and trans-fat. Why: poorer overall health can worsen inflammation and dryness symptoms. World Health Organization+1

7. Avoid: smoking and secondhand smoke. Why: linked to eye damage and dry eye problems. CDC+1

8. Avoid: dehydration (too little water). Why: can worsen dryness and discomfort. World Health Organization+1

9. Avoid: rubbing eyes, especially when itchy. Why: increases surface injury risk. EyeWiki

10. Avoid: unsafe contact lens wear (sleeping in lenses unless doctor says). Why: raises infection and corneal complication risk. EyeWiki+1

FAQs

1. What is CCDF? It is a rare corneal stromal dystrophy pattern with cloudy polygonal spots in the central posterior stroma. Orpha+1

2. Is it dangerous? Usually no—most cases are mild and do not progress or affect vision. EyeWiki+1

3. Will I go blind from CCDF? That is very unlikely; most people keep normal vision, and many need no treatment. Orpha+1

4. Does CCDF need treatment? In general, no treatment is required because it is often asymptomatic and non-progressive. EyeWiki

5. Can eye drops remove the cloudy areas? No proven drop can remove CCDF deposits; drops are used only to treat dryness, irritation, or other surface problems. EyeWiki+1

6. Is CCDF inherited? The genetics are not fully clear in the literature; some reports suggest family cases, but classification discussions note uncertainty and overlap with similar degenerations. Cornea Society+2PMC+2

7. How is it diagnosed? Mainly by slit-lamp exam; specialists may use corneal imaging to document the pattern and depth. EyeWiki+1

8. Can CCDF be confused with other conditions? Yes, it can resemble posterior crocodile shagreen or other stromal findings, so a cornea specialist may compare patterns carefully. EyeWiki+2Cornea Society+2

9. Can I wear contact lenses? Often yes, but lens choice and hygiene matter; specialty lenses like scleral lenses can also help comfort/vision in some corneal disorders. EyeWiki+1

10. Can I do LASIK if I have CCDF? A published case report described LASIK without worsening over years, but refractive surgery decisions must be individualized after full corneal testing. PubMed+1

11. What symptoms should worry me? Pain, strong light sensitivity, thick discharge, a white corneal spot, or sudden vision drop—these suggest infection/erosion and need urgent care. EyeWiki+1

12. Do supplements cure CCDF? No; supplements may support general eye health but do not remove dystrophy changes. National Eye Institute+2APIM+2

13. Is corneal transplant common in CCDF? No—because CCDF is usually mild, transplant is uncommon and considered only if vision is significantly impaired for broader corneal reasons. EyeWiki+1

14. Will CCDF always stay stable? Most descriptions say non-progressive, but every person should still have periodic checks because other eye problems can occur independently. EyeWiki+1

15. What kind of doctor should I see? An ophthalmologist, ideally a cornea specialist, especially if you have symptoms, plan surgery, or need advanced lenses. EyeWiki+1
