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.
Of these two prediabetic states, the latter in particular is a major risk factor for progression to full-blown diabetes mellitus, as well as cardiovascular disease. The American Diabetes Association (ADA) since 2003 uses a slightly different range for impaired fasting glucose of 5.6 to 6.9 mmol/L (100 to 125 mg/dL).
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 nonhealing and recurrent corneal ...
Bullous pemphigoid (a type of pemphigoid) is an autoimmune pruritic skin disease that typically occurs in people aged over 60, that may involve the formation of blisters ( bullae) in the space between the epidermal and dermal skin layers. It is classified as a type II hypersensitivity reaction, which involves formation of anti- hemidesmosome ...
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 40s, the ...
Specialty. ophthalmology. [ edit on Wikidata] Osteo-odonto-keratoprosthesis ( OOKP ), also known as "tooth in eye" surgery, [1] is a medical procedure to restore vision in the most severe cases of corneal and ocular surface patients. It includes removal of a tooth from the patient or a donor.
In mucous membrane pemphigoid, the autoimmune reaction occurs in the skin, specifically at the level of the basement membrane, which connects the lower skin layer (dermis) to the upper skin layer (epidermis) and keeps it attached to the body. When the condition is active, the basement membrane is dissolved by the antibodies produced, and areas ...
Specialty. Dermatology. A vesiculobullous disease is a type of mucocutaneous disease characterized by vesicles and bullae (i.e. blisters). Both vesicles and bullae are fluid-filled lesions, and they are distinguished by size (vesicles being less than 5–10 mm and bulla being larger than 5–10 mm, depending upon which definition is used).
