Sattlerov sloj, imenovan po Hubertu Sattlru, austrijskom oftalmologu, jedan je od pet (ili šest, jer neki autori smatraju vaskularnu regiju sudovnjače kao dva odvojena sloja, Sattlerov i Hallerov sloj,^[1] a neki miske da je lamina fusca bionjačnog ili rožnjačnog porijekla.) slojeva krvnih sudova srednjeg promjera u ržnjačnom sloju oka. Nalazi se između Bruchove membrane, horiocapilarisa i Hallerovog sloja odozdo, odnosno nadrožnjačnog sloja gore.^[2] Čini se da je porijeklo povezano s kontinuiranom diferencijacijom tokom rasta tkiva, pa čak i daljom diferencijacijom tokom odrasle dobi.^[3]^[4]

Metodi mjerenja i klinički utjecaj

Nakon ekscizije, rožnjača djelimično kolabira, a histološki pripravci također mijenjaju lokalni pritisak i sadržaj tekućine u različitim dijelovima tkiva, pa su potrebni preparati s gumenim rastvorom ili drugi, koji mogu očuvati vaskularni status živog tkiva. Novi dijagnostički metodi, posebno optička koherentna tomografija proširile su razumijevanje stvarnog vremena, statusa in vivo različitih slojeva.^[5]

Nekoliko radova pokazalo je vezu između debljine rožnjačinog, Sattlerovog i Hallerovog sloja zdravih osoba i kod ljudi sa dobna povezanost (AMD).^[6] Studije su pokazale značajno smanjenje debljine sloja u odnosu na progresiju AMD-a, što može biti važno za razumijevanje horiopatije u patofiziologiji AMD-a. Međutim, također jake varijacije čak i tokom dnevnog ciklusa,^[7] kao i uticaj optičkih podražaja tokom rasta oka^[8] ukazuju na to da kompleksna funkcija ovog tkiva nije u potpunosti shvaćena i da bi mogao biti jedan od razloga često nađenih razlika između vaskularne veličine Halerovog i Sattlerovog sloja.
