Corneal Ulcer
Ulcerative keratitis
Juga dikenali sebagai: Corneal ulceration, Ulcerative keratitis, Indolent ulcer, Boxer ulcer, Indolent erosion, SCCED
Ringkasnya
A corneal ulcer is a painful open sore on the surface of a dog or cat's eye. While simple ulcers often heal quickly with prompt veterinary care, complicated or non-healing "indolent" ulcers require aggressive medical or surgical treatment to protect your pet's vision.
TL;DR. Luka menyakitkan pada kornea lutsinar; rawatan doktor haiwan segera untuk mengelak komplikasi hingga hilang penglihatan.
Kornea ialah lapisan pelindung jernih mata.
Apa itu?
Kehilangan epitelium kornea (keratitis ulseratif). Superfisial tidak rumit atau rumit (stroma, jangkitan, ulser "mencair"). Ulser indolent (SCCED): tepi epitelium longgar tidak sembuh tanpa debridemen.
Punca dan faktor risiko
Trauma, objek asing, entropion/distikiasis, KCS, paresis fasial. Steroid topikal pada ulser terbuka berbahaya.
"The leading cause of complicated ulcers is the use of topical steroids in a patient with a corneal defect."
Tanda
- Sakit, blefarospasme, defek kelihatan (kardinal)
- Biasa: kemerahan, mukus/nanah, edema (kekaburan kebiruan)
- Kadang-kadang: neovaskularisasi; jarang malasia, abses
Menyipit dan berair adalah tanda sakit klasik.
Diagnosis
Fluorescein (standard emas), slit lamp, tonometri; kultur/sitologi jika dijangkiti/dalam.
Fluorescein menanda defek hijau.
Rawatan
Tidak rumit: antibiotik topikal (cth. Orbifloxacin), Atropine untuk sakit, kolar. Rumit/mencair: serum topikal, Doxycycline, kadang pembedahan. Indolent: debridemen/keratotomi.
Prognosis
Tidak rumit: cemerlang (3–5 hari). Rumit: berjaga-jaga–sederhana. Indolent: baik selepas prosedur tetapi degil.
Pencegahan
Lindungi mata semasa mandi; potong bulu muka; rawat KCS; jangan guna titisan steroid lama.
Bila hubungi doktor haiwan
Setiap mata sakit/merah adalah kecemasan. Mata tertutup, kabur, lelehan kuning-hijau, menggaru mata.
Baka
Boxers: predisposisi ulser indolent.
