Infectious Keratitis: Secreted Bacterial Proteins That Mediate Corneal Damage
Ocular bacterial infections are universally treated with antibiotics, which can eliminate the organism but cannot reverse the damage caused by bacterial products already present. The three very common causes of bacterial keratitis-Pseudomonas aeruginosa, Staphylococcus aureus, and Streptococcus pneumoniae-all produce proteins that directly or indirectly cause damage to the cornea that can resul...
متن کاملCorneal Nerve Damage In Microbial Keratitis.
Barriers that rapidly oppose potential corneal pathogens include innate immunity, tears that form a barrier and contain antimicrobial substances, and blink reflex that helps to spread tears over the cornea and mechanically sweep away pathogens. These protective mechanisms are controlled by nerves that can both stimulate and inhibit immune functions, stimulate tear production, and regulate blink...
متن کاملPACK-CXL: Corneal cross-linking in infectious keratitis.
BACKGROUND Corneal cross-linking (CXL) using ultraviolet light-A (UV-A) and riboflavin is a technique developed in the 1990's to treat corneal ectatic disorders such as keratoconus. It soon became the new gold standard in multiple countries around the world to halt the progression of this disorder, with good long-term outcomes in keratometry reading and visual acuity. The original Dresden treat...
متن کاملCorneal Pyogenic Granuloma: Rare Complication of Infectious Keratitis
BACKGROUND Pyogenic granuloma is an excessive proliferation of granulation tissue that usually develops after minor trauma or surgery. Ocular involvement usually happens on the external surface and cornea is rarely involved. The objective of our report is to describe the clinicopathological feature of this rare disease and give insight on clinical features that help in the diagnosis. CASE REP...
متن کاملCorneal collagen crosslinking in the treatment of infectious keratitis
PURPOSE To report the use of corneal collagen crosslinking in the treatment of infective keratitis not responding to antimicrobial therapy. METHODS Two retrospective case reports of infective keratitis treated with corneal collagen crosslinking. RESULTS In both cases, corneal collagen crosslinking caused a rapid resolution of the infective keratitis, leaving residual stromal scarring. Due t...
