MYELINATED NERVE FIBERS AND VITREORETINAL TUFT

Myelinated nerve nerve fibers have a whitish look as they emerge from the optic nerve in the eye.  Myelination is like insulation around electrical wires.   That myelination exists on the nerves when they exit the eye, but in the eye they are unmyelinated.  Sometimes the myelination will extend in to the eye.  It doesn't cause any problems.  

Vitreoretinal tuft is a traction on the retina from the vitreous bag that fills up the inside of the eye.  As this bag pulls on the retina, it can sometimes be adherent to the retina in a localized place and pull the retina up a little.  A small percentage of these become retinal tears, which can then turn in to detachments which would cause loss of vision.   Therefore they need to be watched with dilated eye exams closely.

CORNEAL ULCER FROM CONTACT LENS OVERWEAR

The photos below are of a corneal ulcer in a patient who frequently sleeps in their "extended wear" contact lenses and doesn't have a good pair of glasses that they like. 

This patient is lucky because the ulcer was just outside the visual axis, meaning that most of her vision should return to normal once the infection is gone and the eye is healed.  This ulcer will take high dosage of very potent topical antibiotics to resolve, followed by anti-inflammatory drops to minimize scarring and maximize vision. 

TREATED RETINAL TEAR

Below is a photo of a treated retina tear. You can see the piece of retina that is broken off. There is a tear underneath it. There are laser scars surrounding it, preventing it from becoming a retinal detachment.

PSEUDOEXFOLIATION GLAUCOMA

Pseudoexfoliation occurs primarily in patients of Scandinavian descent. It is a flaky material that exists on the anterior lens capsule and can also flake off and block the fluid drainage of the eye. This patient ha significant loss of vision in this eye from damage to the optic nerve (as demonstrated by it's lack of good blood perfusion in the bottom picture).

CONJUNCTIVAL CYST

This is a cool picture of a conjunctival cyst. The patient is looking to his left. The cyst grew overnight and stretched the blood vessels, causing a few of them to bleed.

ABMD

This is anterior basement membrane dystrophy, a genetic disease that causes an irregular corneal surface resulting in blurred vision and eye discomfort upon awakening.

"EYELASHITIS"

That is what this 9 year old patient calls this. It's actually blepharitis, a chronic infection of the eyelids.

BEAR TRACKS

Basically bear tracks are pigment on the retina. Kind of like a birth mark.
