Eye Anatomy

The eye is a complex organ that works much like a camera, focusing light rays and forming an image. On the surface of the eye is the cornea, a thin, clear layer of tissue that provides a window for light to pass through. In a healthy eye, the cornea bends or refracts light rays so they focus precisely on the retina in the back of the eye. ...

Cataracts

Each year, cataracts affect millions of people, including more than half of all Americans aged 60 and older. A cataract is a painless clouding of the eye's natural lens that is caused by a buildup of protein. A cataract can form in one or both eyes. If left untreated, cataracts worsen over time and interfere with everyday activities such as reading or driving. Night vision is usually most affected. When cataracts are in their early stages, people are helped by brighter lighting. As cataracts get worse, however, most people require surgery. ...

Glaucoma

Glaucoma is a group of related diseases that damage the optic nerve, resulting in vision loss and possible blindness. Many people affected with glaucoma do not experience symptoms, and may not be aware that they have the disease until they have lost a significant amount of vision. With early detection and treatment, however, eyes can be protected against the serious loss of vision or blindness. Catching glaucoma at an early, treatable stage is one important reason to have regular, thorough eye examinations. A leading cause of blindness and visual impairment in the United States, glaucoma affects patients of all ages. ...

Diabetic Eye Disease

Patients with diabetes are at a higher risk for developing eye conditions as a complication their disease. Over 40 percent of patients diagnosed with diabetes develop some form of eye disease as a result of their disease. Diabetic retinopathy is the most common diabetic eye disease and the primary cause of blindness in the United States. ...

Ocular Hypertension

Ocular hypertension is a condition where the intraocular pressure (IOP) in the eyes is higher than normal. A normal pressure reading falls between 10 mm Hg and 21 mm Hg. Anything greater than 21 mm Hg is considered hypertensive. The increased pressure is caused by a problem in the drainage of fluid produced in the eye. ...

Heidelberg Retinal Tomograph

The Heidelberg Retinal Tomograph, or HRT, is a state-of-the art computerized laser device designed to aid in the diagnosis of glaucoma. This non-invasive procedure scans the eye,  producing 3-dimensional digital images of the optic nerve and retina. The optic nerve is photographed along with deeper layers of the eye resulting in a 3-dimensional topographic map of the retinal surface. ...

Humphrey Visual Field

The Humphrey visual field is a diagnostic test to measure visual fields, or perimetry. The Humphrey visual field test measures the entire area of peripheral vision that can be seen while the eye is focused on a central point. During this test, lights of varying intensities appear in different parts of the visual field while the patient's eye is focused on a certain spot. The perception of these lights is charted and then compared to results of a healthy eye at the same age of the patient to determine if any damage has occurred. ...

Tube Shunt 

The tube shunt is a medical device used in the treatment of glaucoma for those patients not responding to medication or surgical intervention. Used to regulate ocular pressure levels, the tube shunt is a device that drains excess fluid from the eye. The fluid flows through the tube and out of the eye into a reservoir where it can be safely absorbed by surrounding tissue. It is implanted on the outer surface of the eye, but covered by conjunctival tissue so it is not visible to others or felt by the patient. ...

Selective Laser Trabeculoplasty

Selective laser trabeculoplasty, or SLT, is an FDA-approved laser procedure for the treatment of open-angle glaucoma. SLT is an advanced treatment option that lowers eye pressure and increases fluid drainage. It is minimally-invasive and uses low levels of energy to selectively pinpoint the areas of the trabecular meshwork, relieving the symptoms of glaucoma. If needed, the procedure can be repeated several times without causing damage to surrounding tissue. ...

Laser Peripheral Iridotomy

Laser peripheral iridotomy, also known as LPI, is a laser procedure used to lower eye pressure in patients with narrow-angle glaucoma. Narrow-angle glaucoma is a condition that occurs when the angle between the iris and the cornea in the eye is too small, resulting in a blockage of fluid in the drainage channel of the eye. Using a laser, a small hole is made in the iris to increase the angle between the iris and cornea allowing fluid to drain from the eye. ...

Trabeculectomy

Trabeculectomy, also known as glaucoma filter surgery, is a surgical procedure that removes part of the trabecular meshwork of the eye in order to increase the drainage of fluid. A trabeculectomy is one of the most common surgical procedures used to treat open-angle and chronic closed-angle glaucoma. A new drainage passage is created during the procedure by creating a bypass opening in the sclera (the white part of the eye) diverting the fluid to a space outside the eye between the sclera and conjunctiva (the outer covering of the eye).   This is a bypass procedure designed to lower intraocular pressure.  This serves to create a system for bypassing the blocked drainage channels and encourages fluid drainage and reduces eye pressure and the dependence on topical eye drops.  The purpose of the surgery is to reduce the rate of glaucoma.   ...
