Iris Prolapse after Cataract Surgery (Video)

This cataract complication is rarely seen. Here you can see a piece of the iris (the colored part of the eye) that has prolapsed upwards through the cataract incision. This particular surgery was performed with the “scleral tunnel” technique, where the doctor creates the entry incision through the sclera and tunnels into clear cornea before…

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,…

Retinal detachment viewed from the slitlamp (Video)

This video shows a retinal detachment of the eye as viewed from the slit-lamp microscope. In this case, you see a large bullous rhegmatogenous detachment with a retinal tear/hole at the 1 o’clock position (the image is reversed). Unless you are experienced with the retinal exam, this movie may be hard to interpret … retina…

Retained lens material after cataract surgery (Video)

This eye has a small piece of lens nucleus sitting in the bottom of the anterior chamber after successful phaco cataract extraction. This usually occurs when a piece of the hard nucleus gets stuck in the angle and isn’t seen in surgery because of dense arcus or corneal edema (especially sub-incisionally). This nuclear fragment eventually…

“Cell and flare” in the eye (Video)

“Cell and flare” in the eye (Video)

This video demonstrates what cell and flare look like under the slit-lamp microscope. “Cell” is the individual inflammatory cells while “flare” is the foggy appearance given by protein that has leaked from inflamed blood vessels. This finding is commonly seen with uveitis, iritis, and after surgery … and actually seeing it can be challenging for…

Phlyctenule reaction on the cornea (Video)

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)

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)

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…

KP (keratic precipitates) on the back of the cornea (Video)

In this video you can see particles stuck to the back surface of the cornea. These are KP (keratic precipitates) which are clusters of inflammatory cells that tend to congregate and stick to the endothelium during times of AC inflammation (uveitis). As you can see in this video, the KP spots are visible on the…

EKC adenovirus causing viral conjunctivitis (Video)

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)

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. Download this video To download this video, right click on a link below and choose “Save Target As…” cornealaceration.wmv…

Goldman Applanation Mires for Glaucoma (Video)

This video shows the view you have when checking eye pressure (glaucoma check) with the goldman applanation tonometer. This device flattens the corneal surface of the eye, and by determining the amount of force required to flatten a measured area, can calculate the inner ocular pressure. Applanation is one of the harder steps for the…

Video: Asteroid Hyalosis

Asteroid hyalosis describes white floaters in the vitreous humor of the eye. These bodies are different than the typical floater, and usually don’t cause visual disturbances. They are caused by calcium soap deposits and can be associated diabetes, hypertension, and high cholesterol. Though usually visually benign, these rarely cause significant visual disturbance. The opacity usually…
