Keratitis (C0022568)

Definition (CHV) inflammation of the cornea
Definition (CHV) inflammation of the cornea
Definition (MSHCZE) Zánět rohovky. Postiženy mohou být povrchové vrstvy s patrnými defekty v epitelu (např. keratitis dendritica) nebo je postiženo i stroma (např. keratitis parenchymatosa). Příč. mohou být viry (herpes, adenoviry), poranění, cizí tělíska, poleptání, bakterie či plísně. K. se projevuje bolestí, slzením, blefarospasmem, nerovnostmi povrchu. Postižení hlubokých vrstev může vést ke zkalení, přítomny jsou infiltráty, může dojít k vaskularizaci. Následně může dojít k poruchám zraku. Těžké formy vedou k vzniku vředu, indukci iritidy, hypopyon. Léčí se klidem, vyloučením dráždících faktorů (čoček), mydriatiky či cykloplegiky, kauzálními postupy (antibiotické masti, antivirotika). Lokální kortikoidy jsou vyhrazeny jen některým formám (zejm. hlubším, se spoluúčastí imunitních mechanismů, obv. v kombinaci s antimikrobiální léčbou). Nesprávně indikované kortikoidy mohou vést k rychlé progresi zánětu. Někdy jsou zároveň postiženy spojivky (keratokonjunktivitida). Typy k. – viz keratitis. (cit.
