Glaucoma
OUR SPECIALIZED GLAUCOMA SERVICES
The only way to be sure that you are unaffected by glaucoma is to undergo a comprehensive eye examination. Our clinic is well-equipped to diagnose glaucoma as early as possible and to arrest the disease in its earliest stage in the hands of experienced staffs.
Automated Perimetry Examination
The Humphrey Visual Field is a special automated procedure used to measure the entire area of peripheral vision that can be seen.
Lights of varying intensities are presented in different parts of the visual field while patient focuses on a central fixating light. Patient is asked to press a button whenever he or she is able to see the lights presented. The perception of these lights is charted and then compared to results of a healthy eye of the same age group in order to determine if any damage has occurred. This examination is performed easily in less than 15 minutes, and is effective in diagnosing and monitoring the progress of glaucoma.
Glaucoma patients will often undergo this test on a regular basis in order to determine the progression of the disease.
Optical Coherence Tomography (OCT)
Optical coherence tomography (OCT) is an advanced technology used to produce cross-sectional images of the retina. These images can help with the detection and treatment of serious eye condition such as macular holes, macular swelling and optic nerve damage.
OCT uses technology that is similar to CT scans of internal organs, using a scattering of light to rapidly scan the eye to create an accurate cross-section. Each layer of the retina can be evaluated and measured through this image.
The OCT examination takes about less than 5 mins to perform.
Tonometry
Tonometry is a method to determine the intraocular pressure (IOP) of the eye by measuring the tone or firmness of its surface.
Our airpuff non-contact tonometer requires no anesthetic drop as there is no mechanical contact with the eye. The pressure of the eye is measured by delivering a brief puff of air while patient fixates on a green light.
Tonometry is one of the principal tests for glaucoma.
Gonioscopy
Gonioscopy helps to determine the angle where the iris meets the cornea is open and wide or narrow and closed. During the examination, anesthetic eye drops are used to numb the eye. A hand-held lens is gently placed on the eye. There is a mirror on the lens which shows the doctor if the angle between the iris and cornea is closed and blocked (a possible sign of angle-closure or acute glaucoma) or wide and open (a possible sign of open-angle, chronic glaucoma).
Pachymetry
Pachymetry is a simple and painless test that measures the thickness of the cornea, usually in micrometres, when the ultrasonic transducer touches the cornea.
Pachymetry readings can be used in managing glaucoma patients and glaucoma suspects when determining the correlation between the patient’s corneal thickness and the patient’s intraocular pressure. Thicker corneas are associated with artificially elevated IOP measurements, and thinner corneas with artifically reduced IOP measurements.
Corneal pachymetry is considered an important test in the early detection of glaucoma.
