Amiodarone Verticillata – Whorl Keratopathy (Video)

This video shows a cornea with amiodarone verticillata deposits. You can see these as a whorl pattern – the entity is also called whorl keratopathy or hurricane keratopathy. These deposits are benign, difficult to see, and rarely (if ever) have any visual significance. Drugs that can cause this pattern: CACTI Mneumonic: chloroquine, amiodarone, chlorpromazine, tamoxifen,…

Phlyctenule reaction on the cornea (Video)

This slitlamp video shows a phylectenule bump on the surface of the cornea. This inflammatory nodule is caused by a delayed hypersensitivity reaction to staph antigens in a case of bad blepharitis. This case was successfully treated with good lid hygeine, erythromycin ointment, and a mild steroid. Download this video To download this video, right…

Epithelial Ingrowth after Lasik (Video)

This video shows epithelial ingrowth that occurs sometimes after LASIK surgery. If you look closely at the lasik flap, you can see an area of white deposits in an island configuration. These are collections of corneal epithelial cells that have grown under the flap. The surface epithelial cells can proliferate quickly, explaining why surface abrasions…

HSV herpetic dendritic ulcer on cornea (Video)

This video shows the classic dendritic ulcer seen with HSV keratitis. You can see them easily with the use of fluorescein staining (that’s why everything is blue in the movie). These patients typically present with a painful, red eye with photophobia. The HSV is typically the type-1 hsv infection that most people are inoculated with…

EKC adenovirus causing viral conjunctivitis (Video)

This video shows an eye with EKC viral conjunctivitis, caused by the adenovirus. Here you can see numerous subepithelial infiltrates. The easiest way to visualize these is by aiming your slit-lamp light so it comes in from the side and diffusely illuminates the corneal surface. This cornea is suffering from EKC (epidemic keratoconjunctivitis). The adenovirus…

DSEK corneal transplant problems (Video)

This eye has undergone DSEAK (Descemet’s Stripping Automated Endothelial Keratoplasty) also called DSEK. As you can see here, the endothelial transplant has separated from the inner cornea. This was reopposed with sf6 gas in the anterior chamber. DSEK has many advantages over traditional PK and is a wonderful alternative procedure for certain conditions. Download this…

Corneal Dellen after cataract surgery (Video)

Corneal Dellen after cataract surgery (Video)

This cornea has a small dellen (thinning of the corneal stroma) that occured after cataract surgery. The cornea thins when it is dehydrated, and in this case, a localized area of conjunctival edema next to the limbus interfered with the normal tear-blink mechanism. Fortunately, this thinning quickly resolved with aggresive lubrication. Download this video To…

Corneal laceration that’s seidel positive (Video)

This video shows a cornea with a small laceration through the stroma. You can tell that the wound goes all the way into the anterior chamber as the wound is seidel positive when fluorescein is applied.
