Name this finding
Striate Melanokeratosis
What is Striate Melanokeratosis
It is a normal finding in pigmented individuals or a response to trauma or inflamation in lighter pigmented individuals, it represents a migration of pigmented limbal stem cells.
Name the different epithelial iron lines
- Palpebral fissure: Hudson Stahli
- Head of a pterygium: Fleischer
- Head of a filtering bleb: Ferry
- Adjacent to salzmann or other focal elevations
- Anterior to sutures of keratoplasty: Mannis
- After keratorefractive surgery
Name this condition and describe where are the deposits located.
Spheroidal degeneration
Deposits are located withind the bowman’s layer and anterior corneal stroma.
In primary form, They can initially be located in nasal and temporal corneal, since there is a correlation with UV radiation exposure
In the secondary form, it is associated to an area of cronic inflamation and vascularization.
Name this finding and the situation it is associated to?
Adrenochrome deposits
It is associated to topical epinephrine use for glaucoma.
Name this condition
Subepithelial mucinous dystrophy
What gives the cornea with band keratopathy its “Zwiss Cheese appearance”
Calcium is deposited relatevely homogenously in the epithelium, bowman and anterior stroma, but small areas are spared where corneal nerves cross the bowman’s.
What is the most likely diagnosis for this image?
subepithelial quinolone deposits.
This deposits can accumulate after the use of topical cipro/norfloxacine on an <strong>open epithelial defect</strong>.
If this patient is a chronic contact lens user, what is the most likely diagnosis for this finding?
Mucin Balls
