Ophthalmology. Fuchs dystrophy, also referred to as Fuchs endothelial corneal dystrophy ( FECD) and Fuchs endothelial dystrophy ( FED ), is a slowly progressing corneal dystrophy that usually affects both eyes and is slightly more common in women than in men. Although early signs of Fuchs dystrophy are sometimes seen in people in their 30s and ...
Recurrent corneal erosions may occur. The hallmark of Schnyder corneal dystrophy is the accumulation of crystals within the corneal stroma which cause corneal clouding typically in a ring-shaped fashion. [citation needed] Posterior corneal dystrophies – Fuchs corneal dystrophy presents during the fifth or sixth decade of life. The ...
Ophthalmology. Fuchs heterochromic iridocyclitis (FHI) is a chronic unilateral uveitis appearing with the triad of heterochromia, predisposition to cataract and glaucoma, and keratitic precipitates on the posterior corneal surface. Patients are often asymptomatic and the disease is often discovered through investigation of the cause of the ...
Bullous keratopathy, also known as pseudophakic bullous keratopathy ( PBK ), is a pathological condition in which small vesicles, or bullae, are formed in the cornea due to endothelial dysfunction. In a healthy cornea, endothelial cells keeps the tissue from excess fluid absorption, pumping it back into the aqueous humor.
Periodic acid Schiff (PAS) stain. Posterior polymorphous corneal dystrophy ( PPCD; sometimes also Schlichting dystrophy) is a type of corneal dystrophy, characterised by changes in Descemet's membrane and endothelial layer. Symptoms mainly consist of decreased vision due to corneal edema. In some cases they are present from birth, other ...
none. Prognosis. medium. Frequency. rare, about 24 cases have been described in medical literature. Deaths. -. Corneal dystrophy-perceptive deafness syndrome, also known as Harboyan syndrome, is a rare genetic disorder characterized by congenital hereditary corneal dystrophy that occurs alongside progressive hearing loss of post-lingual onset.

Corneal endothelial dystrophy. Corneal endothelial dystrophy is an age-related change that affects the inner layer of the corneal, the endothelium. Leakage of fluid into the cornea causes edema, causing a bluish appearance. This will eventually involve the whole cornea. Bullous keratopathy ( blisters in the cornea) may also form, leading to ...
Congenital hereditary corneal dystrophy (CHED) is a form of corneal endothelial dystrophy that presents at birth. CHED was previously subclassified into two subtypes: CHED1 and CHED2. However in 2015, the International Classification of Corneal Dystrophies (IC3D) renamed the condition "CHED1" to become posterior polymorphous corneal dystrophy ...
