Epithelial edema
generally an early sign of epithelial compromise
- Subepithelial infiltrates
- Punctate epithelial keratitis
- Punctate epithelial erosions
Punctate epithelial erosions
Granular, opalescent, swollen epithelial cells, with focal intraepithelial infiltrates
- Subepithelial infiltrates
- Punctate epithelial keratitis
- Punctate epithelial erosions
Punctate epithelial keratitis
tiny subsurface foci of non-staining inflammatory infiltrates
- Subepithelial infiltrates
- Punctate epithelial keratitis
- Punctate epithelial erosions
Subepithelial infiltrates
is a non-specific term describing any corneal epithelial disturbance
- Filaments
- Superficial punctate keratitis
- Epithelial edema
Superficial punctate keratitis
strands of mucus admixed with epithelium, attached at one end to the corneal surface
- Filaments
- Superficial punctate keratitis
- Epithelial edema
Filaments
subtle cases may manifest with loss of normal corneal luster
- Filaments
- Superficial punctate keratitis
- Epithelial edema
Epithelial edema
is a feature of chronic ocular surface irritation or hypoxia
- Pannus
- Superficial neovascularization
- Epithelial edema
Superficial neovascularization
describes superficial neovascularization accompanied by degenerative subepithelial change extending centrally from the limbus
- Pannus
- Superficial neovascularization
- Epithelial edema
Pannus
are focal areas of acute stromal inflammation composed of inflammatory cells, and cellular and extracellular debris including necrosis
- Ulceration
- Vascularization
- Infiltrates
- Folds
Infiltrates
refers to tissue excavation associated with an epithelial defect
- Ulceration
- Vascularization
- Infiltrates
- Folds
Ulceration
in Descemet membrane
- Ulceration
- Vascularization
- Infiltrates
- Folds
Folds
may follow chronic inflammation with leakage from corneal new vessels
- Seidel test
- Lipid Deposition
- Breaks in Descemet Membrane
- Descemetocele
Lipid Deposition
may be due to corneal enlargement (Haab striae in infantile glaucoma) or deformation
- Seidel test
- Lipid Deposition
- Breaks in Descemet Membrane
- Descemetocele
Breaks in Descemet Membrane
usually only develops when the ocular defences have been compromised
- FUNGAL KERATITIS
