Hypopion layering in the eye (Video)
This video shows an eye with a hypopyon. This is when pus layers out in the front portion of the AC and can be seen as white in the bottom portion of this movie. Hypopions can be sterile or infectious. This particular case was secondary to bacterial endophthalmitis from an exposed tube-shunt (a tube placed…
Hyphema of the eye (Video)
This video shows a layer of blood inside the eye called a hyphema. Hyphemas like this one can occur after blunt injury when the delicate iris arteries bleed into the front anterior chamber of the eyeball. Treatment of hyphemas involves steroid drops (to decrease inflammation) and cycloplegics (to dilate the eye for comfort and to…
Hyphema eye paracentesis (Video)
This video shows an eye with a large hyphema (blood) inside the anterior chamber. The blood has settled into the bottom 35% of the eye, while the upper portion of the AC is dense with free-floating RBCs. In the last half of the movie, I create a paracentesis using a super-blade scalpel. Hyphemas typically occur…
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…
Corneal guttata from Fuch’s dystrophy (Video)
This video shows a cornea with Fuch’s dystrophy. You can see guttata or guttae on the back surface of the cornea. These bumps indicate endothelial pump difficulty, and appear as a “beaten metal” appearance. If you look closely (look where the arrow is pointing) you can see a pock-marked surface that looks like craters on…
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…
Gonioscopy with lens haptic (Video)
This gonioscopy video shows an interesting finding: the blue line is a haptic from an intraocular lens that has poked through the iris into the anterior chamber. Fortunately, the eye pressure was not affected, and there does not appear to be any inflammatory response (ie. you don’t see any PAS in this video). Gonioscopy is…
Fungal corneal ulcer (Video)
This slit-lamp video shows a large, central corneal ulcer that was caused by fusarium fungus. Classically, fungal ulcers are described as gray, feathery borders, with satellite lesions. In reality, the only way to determine the real pathologic cause is with a good culture (molds take forever to grow and require a deep sample) and time…
Removing a metal foreign body from the cornea (Video)
This video shows the removal of metal particle from the surface of the eye using a needle. Metal particles can occur from metal grinding and machine work … the metallic flakes have a tendency to get into hair then fall onto the cornea and stick. This quickly rusts and if not removed soon, can cause…
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 opacity usually…
Pseudoexfoliation Syndrome (Photo)
This photograph of the eye shows pseudoexfoliation on the lens. You can see here a circular ring of whitish material on the lens. As the iris dilates and constricts, the back surface of the iris rubs on the basement-membrane like material and sheds pigment into the aqueous that can clog the trabecular meshwork and cause...
Pseudoexfoliation Syndrome of the Lens (Photo)
This photo shows pseudoexfoliation of the lens. Here you can see a ring of white granular material on top of the lens. This stuff is made of a basement membrane-like material that coats the lens, zonules, and other areas throughout the body.This is important to discover as PXF complicates cataract surgery secondary to zonular instability.
PXF of the lens (Photo)
Here you can see a white material along the pupil margin at the arrow. The iris rubs over this rough surface and pigment can be knocked off the back surface and clog up the trabecular meshwork and cause glaucoma.
