Glaucoma Testing and Treatment

visualfieldimageGlaucoma is a complicated disease in which damage to the optic nerve leads to progressive, irreversible vision loss. Glaucoma is the second leading cause of blindness.

Glaucoma is the generalized name for a group of eye diseases that damage the optic nerve of the eye, preventing the eye from sending accurate visual information to the brain. Glaucoma tests are designed to test your eyes for one of the key symptoms of the disease—increased eye pressure—however only a comprehensive eye exam can reveal whether or not you have glaucoma. Increased pressure inside the eye is often a key indicator of glaucoma, though not exclusively so. Eye doctors can use a number of tests for eye pressure, but will, by default, check for signs of glaucoma as part of a detailed examination of the retina—the light sensitive area at the back of the eye responsible for processing images.

How Does Glaucoma Testing Work?

A glaucoma test is usually part of a routine comprehensive eye exam. Both types of glaucoma tests measure the internal pressure of the eye.

For screening for glaucoma, we use an advanced noninvasive tonometer(I CARE) to gently check the pressure of the eye as without using a numbing eye drop. Another well-recognized test uses a special device called Goldman tonometer (in conjunction with eye-numbing drops) to measure eye pressure.

For better and more accurate diagnosis and treatment of Glaucoma we also use other tests include Visual Field test, OCT( Optical Coherence Tomography), Gonioscopy and Pachymetry.

While increased eye pressure is a key indicator of the disease, it does not necessarily mean you have a glaucoma diagnosis. In fact, the only way to detect glaucoma is to have a detailed, comprehensive eye exam that often includes dilation of the pupils. ,

So “true” glaucoma testing actually involves examining the retina and optic nerve at the back of the eye for signs of the disease.Visual Field 244768,1306767047,6

Glaucoma Treatment

Depending on the severity of the disease, treatment for glaucoma can involve the use of medications, conventional (bladed) surgery, laser surgery or a combination of these treatments. Medicated eye drops aimed at lowering IOP usually are tried first to control glaucoma.



Because glaucoma is often painless, people may become careless about strict use of eye drops that can control eye pressure and help prevent permanent eye damage. In fact, non-compliance with a program of prescribed glaucoma medication is a major reason for blindness resulting from glaucoma.
If you find that the eye drops you are using for glaucoma are uncomfortable or inconvenient, never discontinue them without first consulting your eye doctor about a possible alternative therapy.
All glaucoma surgery procedures (whether laser or non-laser) are designed to accomplish one of two basic results: decrease the production of intraocular fluid or increase the outflow (drainage) of this same fluid. Occasionally, a procedure will accomplish both.
Currently the goal of glaucoma surgery and other glaucoma therapy is to reduce or stabilize intra ocular pressure (IOP). When this goal is accomplished, damage to ocular structures – especially the optic nerve – may be prevented.

Glaucoma can cause slight to severe vision loss, and is often discovered only after the disease is present—that’s why glaucoma testing is so important.


Advanced Technology

Using cutting-edge technology we can diagnose eye conditions in their early stages, which is not possible with regular eye exam. Many eye diseases, if detected early enough, can be prevented or treated successfully before the vision deteriorate permanently. We recommend annual total advanced eye health exam for everyone.

Below are some of the advanced technology that we use in our Advanced Total Compréhensive Eye Examination.

Optical Coherence Tomography (OCT)

OCT is a quick, non-invasive, non-contact and painless procedure that revolutionized the way we diagnose and treat eye diseases. It provides fine details of each layer of the cornea and anterior segment of the eye, retina, and changes to the optic nerve.

As part of our preventative eye care, we incorporate screening OCT to our Advanced Total Eye Health Examination, therefore the eye conditions can be detected early to be treated in their early stages long before they become detectable by regular eye exams. Early detection is vital for early treatment and preventing vision loss.

OCT is used in the diagnosis of the diabetic retinopathy, age-related macular degeneration (AMD), macular oedema (accumulation of fluid within the retina), central serous retinopathy, macula hole, vitreomacular traction, other retinal disorders, glaucoma, medication toxicity, Keratoconus, pellucid marginal degeneration and other disorders of the cornea.

An Optical Coherence Tomography scan (OCT) is the latest advancement in imaging technology. Similar to ultrasound, this diagnostic technique employs light rather than sound waves to achieve higher resolution pictures of the structural layers of the back of the eye.

With an OCT scan, doctors are provided with color-coded, cross-sectional images of the retina, optic nerve, cornea and anterior segment of the eye. Using information obtained by OCT our doctor can detect the eye diseases in the early stage before they are become detectable by a regular eye exam.

Early detection is vital for early treatment and prevention.

Visual Field Testing

We use computerized instrument, called Humphrey Field Analyzer by Carl Zeiss globally recognized as gold standard for diagnosing and managing glaucoma.

Visual Field Analyzer is a none invasive sophisticated technology that  provides information regarding the location of any disease processes or lesion throughout the visual pathway , enabling your eye doctor to diagnose conditions such as glaucoma, stoke, brain tumour, brain hemorrhage and their exact location in the brain.

A visual field test measures how much 'side' vision you have. It is a straightforward test, painless, and does not involve eye drops. Essentially lights are flashed on, and you have to press a button whenever you see the light. Your head is kept still and you have to place your chin on a chin rest. The lights are bright or dim at different stages of the test. Some of the flashes are purely to check you are concentrating.

Each eye is tested separately and the entire test takes 15-45 minutes. Your eye doctor may ask only for a driving license visual field test, which takes 5-10 minutes.

Corneal Topography

Our cutting edge advanced corneal topographer, allows your eye doctor to diagnose and monitor abnormalities of the cornea such as Keratoconus. They are also able to create fully customized contact lenses enabling them to successfully fit individuals who have previously failed with standard contact lenses.

Keratograph 5M

Empress Eye Clinic

Keratograph 5M, is a non-invasive technologically advanced instrument, used by eye doctors at Empress Eye Clinic, to accurately diagnose and initiate a personalized treatment plan for dry eye disease.

Digital Retinal Imaging

Digital Retinal Imaging allows your eye doctor to evaluate the health of the back of your eye, the retina. It is critical to confirm the health of the retina, optic nerve and other retinal structures. The digital camera snaps a high-resolution digital picture of your retina. This picture clearly shows the health of your eyes and is used as a baseline to track any changes in your eyes in future eye examinations.


Treatment of Eye Diseases


Utilizing cutting edge technology  Drs. Heshmati  ,and Habib  diagnose and manage, with greater precision, diseases like Glaucoma, Macular Degeneration, Keratoconus, Retinal diseases, Cataracts ,Iritis, Uveitis, and Ocular surface diseases . The sooner the condition is diagnosed and treated,  the better the outcome. We are taking an aggressive approach to diseases that previously had few treatment options. Great advances have been made in the treatment of these diseases.

Empress Eye Clinic makes it an imperative that all staff members are up-to-date on the latest technology and techniques to make your visit to our clinic as comfortable and effective as possible. As ophthalmic and optometric technology changes, it is critical that our eye doctors have all the right eye care qualifications and follows the latest developments in eye care.
