The Epley maneuver or repositioning maneuver is a maneuver used to treat benign paroxysmal positional vertigo of the posterior or anterior canals

Nystagmus is a vision condition in which the eyes make repetitive, uncontrolled movements. These movements often result in reduced vision and depth perception and can affect balance and coordination. These involuntary eye movements can occur from side to side, up and down, or in a circular pattern.

In dark or dim light, the pupil dilates to allow more light into the eye to improve vision. Normal pupil size tends to range between 2.0 and 5.0 millimeters, depending on the lighting. The younger you are, the larger your pupils tend to be.

Electronystagmography (ENG) is a diagnostic test to record involuntary movements of the eye caused by a condition known as nystagmus. It can also be used to diagnose the cause of vertigo, dizziness or balance dysfunction by testing the vestibular system.

In medicine, the caloric reflex test is a test of the vestibulo-ocular reflex that involves irrigating cold or warm water or air into the external auditory canal.

This test stimulates your acoustic nerve by delivering cold or warm water or air into your ear canal. When cold water or air enters your ear and the inner ear changes temperature, it should cause fast, side-to-side eye movements called nystagmus. The test is done in the following way: Before the test, your ear, especially the eardrum, will be checked. This is to make sure it is normal. One ear is tested at a time. A small amount of cold water or air is gently delivered into one of your ears. Your eyes should show an involuntary movement called nystagmus. Then they should turn away from that ear and slowly back. If water is used, it is allowed to drain out of the ear canal. Next, a small amount of warm water or air is gently delivered into the same ear. Again, your eyes should show nystagmus. Then they should turn toward that ear and slowly back. Your other ear is tested in the same way.

Nystagmus is a condition of involuntary (or voluntary, in rare cases) eye movement, acquired in infancy or later in life, that may result in reduced or limited vision. Due to the involuntary movement of the eye, it has been called "dancing eyes"

Stephen Slade shows a 1 week post op patient after DSAEK. DSAEK is an excellent option for many patients with corneal disease. In DSAEK, only the thin, inner layer is replaced, so the healing is typically much faster than a full thickness cornea graft.

Surgery is performed by Kami Parsa M.D. The patient is a 55 year old with a history of previous upper eyelid blepharoplasty with excessive skin removed from both upper eyelids which resulted in bilateral lagophthalmos. Patient could not close her eyes and had problems with severe dry eyes.

A chalazion is a swollen bump on the eyelid. It happens when the eyelid’s oil gland clogs up. It may start as an internal hordeolum (stye). At first, you might not know you have a chalazion as there is little or no pain. But as it grows, your eyelid may get red, swollen, and sometimes tender to touch. If the chalazion gets large, it can press on your eye and cause blurry vision. Rarely, the whole eyelid might swell.

A stye (also called a hordeolum) is a small, red, painful lump that grows from the base of your eyelash or under the eyelid. Most styes are caused by a bacterial infection. There are two kinds of styes: External hordeolum: A stye that begins at the base of your eyelash. Most are caused by an infection in the hair follicle. It might look like a pimple. Internal hordeolum: A stye inside your eyelid. Most are caused by an infection in an oil-producing gland in your eyelid.

Acanthamoeba keratitis is a rare disease in which amoebae invade the cornea of the eye. It may result in permanent visual impairment or blindness.

Most cataracts are associated with the aging process and are common among older Americans. In fact, according to the National Eye Institute (NEI), 68.3 percent of Americans 80 and older had cataracts in 2010. And the prevalence of cataracts in the U.S. is expected to grow significantly in the years ahead, due in part to the aging of the population. In 2010, roughly 24.4 million Americans had cataracts, and that number is projected to grow to 50.2 million by the year 2050, according to NEI.

Most retinal tears need to be treated by sealing the retina to the back wall of the eye with laser surgery or cryotherapy (a freezing treatment). Both of these procedures create a scar that helps seal the retina to the back of the eye. This prevents fluid from traveling through the tear and under the retina, which usually prevents the retina from detaching. These treatments cause little or no discomfort and may be performed in your ophthalmologist’s office. With laser surgery, your ophthalmologist uses a laser to make small burns around the retinal tear. The scarring that results seals the retina to the underlying tissue, helping to prevent a retinal detachment.
