Ob allergisch, autoimmun, toxisch oder mechanisch bedingt – die nicht-infektiöse Konjunktivitis
ist ein Chamäleon unter den Augenerkrankungen. Dieser Beitrag beleuchtet differenzialdiagnostische
Herausforderungen, pathophysiologische Mechanismen und moderne Therapieansätze von
Keratokonjunktivitis vernalis über Graft-versus-Host-Erkrankung bis hin zum okulären
Pemphigoid.
Abstract
The conjunctiva is a central component of the ocular mucosal system and, together
with the Meibomian glands of the eyelids and the lacrimal glands, fulfills nutritive
and defensive functions on the ocular surface. The conjunctiva is integrated into
a dense neural and immunological network called the “Conjunctiva-associated Lymphoid
Tissue” (CALT) [1]
[2]. This network perceives various stimuli and responds in a finely tuned manner to
provide protection while minimizing collateral damage. This must be viewed in the
context of resident microorganisms (“commensal flora”) colonizing the conjunctiva
(microbiome), and numerous biophysical factors that can disrupt the homeostasis of
the ocular surface. Inflammatory changes are of primary concern and are differentiated
according to their origin as either infectious or non-infectious. This CME
article provides an overview of non-infectious inflammatory pathologies.
