Presentation
Patients often present in the fifth to sixth decade of life with blurry morning vision that increases in duration as the disease progresses. [jhu.pure.elsevier.com]
Numerous vesicular water clefts (subepithelial bullae, SB) were present in the superficial stroma (Fig. 4). [healio.com]
[…] inflammatory cells and neovascularization are present within adjacent stroma in some cases. [entokey.com]
Corneal flattening or thinning and endothelial opacities may also be present. A prominent Schwalbe’s line, as well as iris and angle findings, may also be present. [reviewofcontactlenses.com]
These patients will be the most symptomatic, often presenting with classic RCE morning symptoms. [decisionmakerplus.net]
Entire Body System
- Inflammation
Keratitis This is an inflammation of the cornea that sometimes occurs with infection after bacteria or fungi enter the cornea. These microorganisms can enter the eye after deep injury, causing infection, inflammation, and ulceration of the cornea. [my.clevelandclinic.org]
Symptoms include pain, burning, inflammation of the eye, as well as eye irritation, with foreign body sensation. [columbiaeye.org]
Carolina Eyecare Physicians offers treatment for many corneal and external eye diseases, including: Scleritis (inflammation of the sclera, the white part of the eye) Keratitis (inflammation of the cornea) Corneal ulcers and abrasions Fuchs’ Dystrophy [carolinaeyecare.com]
Corneal dystrophies are common genetic conditions which cause changes to your cornea without any inflammation, infection or other eye disease. Corneal dystrophies affect the clearness of your cornea and usually involve both eyes. [rnib.org.uk]

Symptoms may include: Blurry vision Distorted vision Tiny, painful blisters Cornea swelling Glare Pain Light sensitivity Common Corneal Dystrophies Fuchs’ Dystrophy Lattice Corneal Dystrophy Epithelial Basement Membrane Dystrophy Macular Corneal Dystrophy [southtexaseye.com]
Epithelial swelling damages vision by changing the cornea's normal curvature, and causing a sight-impairing haze to appear in the tissue. Epithelial swelling will also produce tiny blisters on the corneal surface. [web.archive.org]
In Fuchs dystrophy these cells deteriorate (“die off”) and the cornea fills with water and swells. The swelling worsens and blurred vision occurs that is worse in the morning, but gradually improves throughout the day. [cornealdystrophyfoundation.org]
- Surgical Procedure
Recent advances in our understanding of the genetic and pathophysiological mechanisms of the disease, as well as the application of new imaging modalities and less invasive surgical procedures, present new opportunities for improved outcomes among patients [jhu.pure.elsevier.com]

Autonomic disturbance includes orthostatic hypotension, cardiac conduction abnormalities, and dysfunction of perspiration. Symptoms Ocular: Corneal sensitivity is reduced or absent. [ncbi.nlm.nih.gov]
Eyes
- Photophobia
An abnormal sensitivity to light (photophobia) and the sensation of foreign material within the eye may also occur. [cornealdystrophyfoundation.org]
Patient remains asymptomatic until epithelial erosions precipitate acute episodes of ocular hyperemia, pain, and photophobia. [en.wikipedia.org]
In practice, the ophthalmologist manages functional symptoms such as recurrent erosions, visual loss and amblyopia, photophobia, foreign body sensation, and sometimes pain and aesthetic concerns. [em-consulte.com]
There was no history of photophobia. The parents were not related to each other before marriage. The general physical examination did not reveal any abnormality. [healio.com]

- Corneal Opacity
In Thiel–Behnke dystrophy, sub-epithelial corneal opacities form a honeycomb-shaped pattern in the superficial cornea. [en.wikipedia.org]
Differential diagnoses would include any diseases that present with corneal opacities or epithelial damage. [decisionmakerplus.net]
The density of the corneal opacity did not permit clear (Visualization of deeper layers of the cornea. The epithelial edema did npt clear appreciably even with 50 per cent glycerine. [healio.com]
If your dog has any of these other health issues or the corneal opacities are only in one eye, they may be secondary corneal degeneration rather than inherited dystrophy. [ashgi.org]

- Visual Acuity Decreased
Visual acuity decreases as opacification progresses with age. Recurrent erosions are seen frequently. Homozygote cases have more severe symptoms. [journals.lww.com]
Symptoms Decreased to normal visual acuity. Recurrent corneal erosions are less severe than in RBCD and TBCD. [ncbi.nlm.nih.gov]
- Eye Swelling
Iridocorneal endothelial syndrome (ICE) – This condition involves changes in the iris (the colored part of the eye), swelling of the cornea, and the development of glaucoma. [columbiaeye.org]
Skin
- Blister
Symptoms may include: Blurry vision Distorted vision Tiny, painful blisters Cornea swelling Glare Pain Light sensitivity Common Corneal Dystrophies Fuchs’ Dystrophy Lattice Corneal Dystrophy Epithelial Basement Membrane Dystrophy Macular Corneal Dystrophy [southtexaseye.com]
As the disease gets worse, small blisters may form. The blisters get bigger and may eventually break. This causes eye pain. Fuchs' dystrophy can also cause the shape of the cornea to change, leading to more vision problems. [medlineplus.gov]
It creates painful blisters on the cornea and makes it hard to see depth and colors. This disease also makes it difficult to clearly see faces when light shines from behind the person. Dr. [vsp.com]
Also, tiny blisters may form in the cornea. The blisters get bigger and eventually break open, causing eye pain. People in their 30s and 40s may have Fuchs’ dystrophy but not know it. Vision problems might not appear until age 50 or later. [carolinaeyecare.com]
Herpes zoster can cause blisters or lesions on the cornea, fever, and pain from nerve fibers. Corneal lesions usually heal by themselves, but antiviral treatment may shorten the course of disease. [my.clevelandclinic.org]
- Macula
The macula has a high density of cones, ganglion cells, and pigment within bipolar and ganglion cells. The central 1.5 mm area of the macula is the fovea. [patient.info]
Neurologic
- Nystagmus
In CHED1 the cornea is often clear at birth, corneal opacification is slowly progressive, and nystagmus is generally absent. [link.springer.com]
Patients have night blindness, reduced acuity, high myopia, nystagmus and strabismus. There are two major types - the complete form and the incomplete form. [patient.info]
Visual impairment is often associated with additional eye abnormalities, including "lazy eye" (amblyopia), eyes that do not look in the same direction (strabismus), involuntary eye movements (nystagmus), and increased sensitivity to light (photophobia [ghr.nlm.nih.gov]
Usually, these patients have associated nystagmus with minimal or no photophobia and watering. [ijo.in]

Workup
X-Ray
- Ground Glass Appearance
Congenital hereditary endothelial corneal dystrophy is characterized by a diffuse ground-glass appearance of both corneas and markedly thickened (2–3 times thicker than normal) corneas from birth or infancy. [en.wikipedia.org]
Case I: Ground-glass appearance of cornea in both eves. Fig. 3. Case 3: Showing corneal haziness on both sides. Fig. 4. [healio.com]
While in the beginning stages there are clear spaces between lesions, over time these spaces opacify and take on a ground glass appearance. [eyewiki.aao.org]
These changes, together with the decreased fibril density, scatter light and result in a ground-glass appearance of the cornea. The endothelial cells are scant or degenerated when present. [ojrd.biomedcentral.com]
Treatment
Preventative Treatment Avoiding or minimizing contact lens wear in patients with preexisting epithelial disease Pharmocologic Treatment Hyperosmotics The goal of treatment is to improve visual acuity by deturgescence of the stroma or epithelium. [decisionmakerplus.net]
Medical treatments consist of drops to promote healing, ointments, hyperosmotic agents and bandage contact lenses. Less invasive surgical treatments are used as second line therapy (phototherapeutic keratectomy, lamellar keratectomy). [em-consulte.com]
Vision slowly deteriorates, but treatment is not usually necessary until the seventh or eighth decade of life. [reviewofoptometry.com]
Corneal Dystrophy Treatment Options Manhattan corneal surgeon Dr. Belmont recommends an appropriate treatment option based on your type of corneal dystrophy and how advanced the condition is. [belmonteyecenter.com]
Beginning with basic science, examination techniques and epidemiology, the following chapters discuss the diagnosis and the medical and surgical treatment of numerous different conditions and diseases that may affect the cornea. [books.google.com]
Prognosis
Prognosis - there is no progression. [patient.info]
Treatment and prognosis Most patients with PPMD are asymptomatic and are diagnosed on routine eye exam. These patients usually have a great prognosis and often do not require any treatment. [webeye.ophth.uiowa.edu]
Prognosis Although there are many more forms of corneal dystrophy, essentially there are three inherited classical varieties and the progress and likely outcome varies with each. 1. [eyecaretrust.org.uk]
Br J Ophthalmol 1986, 71 : 130–44. 5 Krachmer JH : Posterior polymorphous corneal dystrophy: a disease characterised by epithelial-like endothelial cells which influence management and prognosis. [nature.com]
In the absence of longitudinal data, the hearing prognosis is presently unclear in the very young, sporadic CHED patients. [ojrd.biomedcentral.com]
Etiology
Certain conditions have both an underlying etiology and multiple body system manifestations due to the underlying etiology. [icd10coded.com]
Etiology Reis-Bücklers corneal dystrophy is caused by a specific mutation in the TGFBI gene (5q31). [orpha.net]
This is in contrast to other etiologies of congenital corneal clouding like Peter’s anomaly or a limbal dermoid, which can vary in size/location and often obscure underlying iris. [reviewofophthalmology.com]
Therefore, any unusual pattern of corneal opacities associated with corneal neovascularization is not a dystrophy and clinicians should investigate other etiologies. [reviewofoptometry.com]
The etiology is not completely understood. The gene for ERED remains to be mapped to a specific chromosomal locus. [ojrd.biomedcentral.com]
Epidemiology
Chapters on epidemiology, embryology, non-syndromic hearing loss, and syndromic forms of hearing loss have all been updated with particular attention to the vast amount of new information on molecular mechanisms, and chapters on clinical and molecular [books.google.com]

Preventative Treatment Avoiding or minimizing contact lens wear in patients with preexisting epithelial disease Pharmocologic Treatment Hyperosmotics The goal of treatment is to improve visual acuity by deturgescence of the stroma or epithelium. [decisionmakerplus.net]
Normally, the oil from these glands coats the eye's surface and prevents tear evaporation. [medicinenet.com]
Is there anything I can do to prevent my Fuchs Dystrophy from getting worse? No, nothing that we know of. However, talk with your ophthalmologist for steps you may be able to take to help alleviate your symptoms (make you feel better). [hopkinsmedicine.org]
There is no known prevention for Fuchs' dystrophy. 2. What Causes It? Fuchs' dystrophy can have a genetic cause, but it also can occur without a previous family history of the disease. In many cases, the cause is unknown. 3. [allaboutvision.com]
