EMBRIOLOGI DAN ANATOMI KORNEA PADA MATA.pptx

Hinweis der Redaktion

  1. Surface Ektoderm menutup lubang lensa dan membentuk epitel kornea (lihat Gambar 4-6D). Proses ini diikuti oleh 3 gelombang migrasi berturut-turut dari sel-sel yang berasal neural crest cell (Gambar 4-17; lihat juga Gambar 4-6E). Gelombang pertama menimbulkan endotel kornea, melewati antara permukaan ektoderm dan vesikel lensa anterior. Gelombang kedua melewati antara endotel dan epitel untuk membentuk keratosit stroma kornea. Gelombang ketiga, terdiri dari sel-sel puncak saraf dan asal mesodermal, berkontribusi terhadap perkembangan iris. Sel-sel endotel kornea bertemu dengan iris yang sedang berkembang, membentuk sudut reses.
  2. Perkembangan kornea di central region. A, Pada hari ke 39, epitel 2 lapis bertumpu pada lamina basal dan dipisahkan dari endotel (gelombang pertama) oleh ruang aseluler yang sempit. B, Pada minggu ke 7, sel ektomesenkim yang berasal dari puncak saraf dari perifer bermigrasi ke ruang antara epitel dan endotel (gelombang kedua). C, Sel mesenkim (keratosit masa depan) tersusun dalam 4-5 lapisan tidak lengkap pada usia kehamilan 7,5 minggu; beberapa fibril kolagen hadir di antara sel. D, Pada usia 3 bulan, epitel memiliki 2-3 lapisan sel, dan stroma memiliki sekitar 25-30 lapisan keratosit yang tersusun lebih teratur di bagian posterior. Membran Descemet yang tipis dan tidak rata terletak di antara keratosit paling posterior dan satu lapisan endotel
  3. Epitel : merupakan barrier terdepan yang terdiri dari beberapa lapis sel yang sangat rapat sulit diinvasi oleh mikroba, jika tidak ada port d entry kecuali bbrp bakteri lainnya yg bisa langsung menembus salah satunya sprit gonorhea Membran bowan : tidak dapat brgenerasi dan akan membentuk jaringan sikatrriks. Terdiri atas kolagen I dan IV Stroma : lapisan yang paling tebal di kornea 90% bagian dari kornea. Terdiri atas air dan berbagai jenis kolagen. Membran descement : merupaka “true basement membrane : seiring usia diproduksi terus menerus, dan merupakan membrane yang sangat resisten terhadap trauma dan dapat bergenerasi. Kolagen tipe iv banyak ditemukan disini. Lapisan endotel : permukaan kornea, lapisan yg tersusun oleh sel2 berbentuk hesagonal yang saling mengunci.
