Diagnostics

 

AEI is a full service eye care facility with advanced diagnostic, therapeutic and surgical services. 

The ophthalmic diagnostic division has the most up to date diagnostic equipment, which is not readily available at many other centers (UBM ultra-sound, Heidelberg Retinal Tomography, Anterior Segment Visante OCT, Preferential Hyperacuity Testing). The use of advanced diagnostics ensures earlier diagnosis and management of your disease.

 

FOR CATARACT PATIENTS

Atlas Topography

atlasTo care for your cataract, Atlas corneal topography and corneal wave front analysis are used to help plan your surgery and choose an implant that will result in the clearest vision. The Atlas Topography Unit helps determine the exact location of your astigmatism and of your cornea – both extremely important factors in determining the best way to treat your cataract. The information obtained from topography also helps improve the accuracy the calculations used to determine the power of the intraocular lens that is inserted into your eye at the time of cataract surgery. The Atlas examination is not covered by OHIP for the assessment of cataract patients. The cost of the test can be claimed on your income tax return, (Line 330 ). Atlas topography is an optional test to you, the patient. It is your choice to have an Atlas exam. It is valuable for all cataract patients and is recommended, but should you decide to decline this test the standard of care will continue to be delivered to you and every effort will be made to manage your eye condition in the best manner possible. We believe all cataract patients will benefit from Atlas topography, as it enables us to plan your cataract surgery with higher degree of precision and recommend an implant that will give you the clearest vision.

Wavefront Analysis

Wavefront analysis uses a special device to precisely measure the unique irregularities and variations in the cornea. This analysis has been compared to taking a fingerprint of the eye.

With your chin resting on the device, you will be asked to stare past what is called a target light. A sensor will measure the irregularities in the wavefront pattern of the light reflecting from your cornea.

Wavefront measuring devices create a precise map of the cornea. It is very detailed and records subtle distortions in your cornea. Using the information from this map, Dr. Anjema can select the intraocular lens used in your surgery to correct for some of these measured distortions, giving you clearer vision than would be possible with conventional lenses.

Wavefront analysis is not covered by OHIP. The cost of this test can be claimed on your income tax return, (Line 330) and is optional to you, the patient.

 FOR MACULAR DEGENERATION,
DIABETES AND RETINAL DISEASE

Overview

To screen for your macular degeneration, diabetes, and other retinal problems, laser imaging and macular mapping are used to help diagnose and manage your disease more accurately, and to prevent blindness. For diabetes, macular degeneration, and other retinal diseases, OCT evaluation is combined with Preferential Hyperacuity Perimetry (PHP). AMD  
=

PHP

Preferential Hyperacuity Perimetry (PHP) was developed recently by North American retinal specialists. The PHP maps your macular function in response to a pinpoint target. The goal of the PHP test is to identify which part of the back of your eye (retina and macula) is not seeing as well as other areas. It is a very sensitive screening test which finds disease earlier than eye physicians can see without the screening test.

In February, 2010, the world renowned Wilmer Eye Institute at Johns Hopkins University in Baltimore, Maryland, USA, conducted a study called the AMD-DOC Study. In this study, the doctors found that PHP testing is a very sensitive test for detecting macular disease before it can be seen by the eye surgeon.

The value of the PHP test to you, the patient, is that your eyes will be screened for blinding diseases such as macular degeneration before your eye surgeon can detect the problem. Ultimately, we can treat you sooner and preserve your vision. For patients with macular degeneration, the PHP is valuable for monitoring the health of your macula prior to and during drug injections.

The PHP test is not covered for the assessment of cataract patients. The cost of the test can be claimed on your income tax return, (Line 330 ). PHP Test is an optional test to you, the patient.

 FOR GLAUCOMA DETECTION & MONITORING

Overview

Glaucoma is a progressive disease of the optic nerve that can lead to permanent loss of vision. Clinical studies have confirmed that early detection and treatment of glaucoma can slow or prevent the progression of permanent optic nerve.

There are new state of the art technologies that measure and analyze the optic nerve in a more precise way, and allow for detection of subtle changes over time.

HRT

=

Wavefront Analysis

The Heidelberg Retina Tomograph (HRT) is a proven, essential tool for detecting and managing glaucoma and disease of the optic nerve, especially for assisting in the identification of early disease and tracking progression. The Heidelberg Retina Tomograph (HRT) is a confocal scanning laser ophthalmoscope. A laser light scans the retina in 24 millisecond sequential scans, starting above the retinal surface, then capturing parallel images at increasing depths. The stacks of images can be combined to create a three-dimensional (3-D) topographic image of the retina. Images are aligned and compared using TruTrack™ software for both individual examinations and for detecting change between examinations.

There are new state of the art technologies that measure and analyze the optic nerve in a more precise way, and allow for detection of subtle changes over time. These technologies are called the Heidelberg Retinal Tomograph (HRT) and Ocular Coherence Tomography (OCT). These tests take digital images of the back of your eye and computers evaluate the images to provide information about your glaucoma and the optic nerve head. The HRT test is not covered for the assessment of glaucoma patients. The cost of the test can be claimed on your income tax return, (Line 330 ). The HRT test is an optional test to you, the patient.

It is your choice to have this test. Dr. Anjema may recommend you have this test, but should you decide to decline, the standard of care will continue to be delivered to you and every effort will be made to manage your eye condition in the best manner possible.

 

 

 FOR REFRACTIVE SURGERY
& CORNEAL DISEASE

 

=

Overview

To care for corneal problems, laser imaging is used to help diagnose and manage your disease more accurately, and to prevent blindness.

For corneal care and anterior eye assessment Visante Anterior Segment OCT is used.

=

Visante OCT

The value of the Visante OCT is that it provides high resolution corneal images and documentation of the anterior segment of the eye that allow for precise evaluation a number of conditions – post LASIK flap evaluation, keratoconus, irregular astigmatism, narrow angle glaucoma, safety of refractive surgery, complex and complicated cataract surgery planning.

In particular the Visante OCT is invaluable in the planning and management of phakic implants (ICL surgery).

Most importantly, this test helps your surgeon decide the best treatment for your eyes to prevent you from losing your vision. It will help prevent loss of vision from the damaging effects of eye disease.

The Visante Anterior Segment OCT is not covered by OHIP. Visante Anterior Segment testing is performed as needed. The cost of this test can be claimed on your income tax return, (Line 330). Visante OCT is an optional test to you, the patient.
