DIAGNOSTIC PROCDURES
Fluorescein Angiography, Optical Coherence Tomography, Perimetry
A fluorescein angiography is a medical procedure in which a fluorescent dye is injected into the bloodstream. The dye highlights the blood vessels in the back of the eye so they can be photographed.
This test is often used to manage eye disorders. Your doctor may order it to confirm a diagnosis, determine an appropriate treatment, or monitor the condition of the vessels in the back of your eye.
​
Optical coherence tomography (OCT) is a non-invasive imaging test. OCT uses light waves to take cross-section pictures of your retina.
With OCT, your ophthalmologist can see each of the retina’s distinctive layers. This allows your ophthalmologist to map and measure their thickness. These measurements help with diagnosis. They also provide treatment guidance for glaucoma and diseases of the retina.
​
A perimetry test (visual field test) measures all areas of your eyesight, including your side, or peripheral, vision.
To do the test, you sit and look inside a bowl-shaped instrument called a perimeter. While you stare at the centre of the bowl, lights flash. You press a button each time you see a flash. A computer records the spot of each flash and if you pressed the button when the light flashed in that spot.
At the end of the test, a printout shows if there are areas of your vision where you did not see the flashes of light. These are areas of vision loss.
THERAPEUTIC PROCEDURES
Laser treatments such as Panretinal Photocoagulation, Focal Laser Treatment, Yag Laser Capsulotomy, Yag Laser Iridotomy and etc.
Panretinal photocoagulation (PRP) is a mainstay of therapy for retinal ischemic disease. The procedure involves creating thermal burns in the peripheral retina leading to tissue coagulation, the overall consequence of which is improved retinal oxygenation.Panretinal Photocoagulation (PRP) is a type of laser treatment for the eye. It is used in people who have developed new abnormal blood vessels at the back of the eye in the retina or in the drainage system within the eyeball.
The PRP laser treatment prevents abnormal new vessels on the retina and in the drainage system of the eyeball from growing and encourages existing ones to shrink and scar up. This makes them less likely to bleed into the jelly in the eye ball (vitreous haemorrhage) or to cause a painful type of high pressure within the eye (neovascular glaucoma).
​
Focal laser is a procedure used to treat leaking blood vessels and edema (fluid buildup) in the retina. The laser creates heat that seals the vessels and vaporizes fluid in the area. Tissues in the retina also become thinner. The area of leaking vessels is smaller, creating less fluid buildup. Focal laser treatment will not give you back lost vision, but it can keep vision loss from getting worse.
​
A Yag capsulotomy is a special laser treatment used to improve your vision after cataract surgery. It is a simple, commonly performed procedure which is very safe.
​
A Yag laser iridotomy is performed almost exclusively for patients with narrow angles, narrow angle glaucoma, or acute angle closure glaucoma. Aqueous fluid is made in the ciliary body of the eye, which is situated behind the iris. The aqueous fluid primarily escapes the eye by flowing between the lens and iris of the eye, and then drains via the trabecular meshwork, which is located in the angle of the eye (where the front clear cornea meets the iris, essentially). If the flow of aqueous fluid to the drainage angle is obstructed by a forwardly bowed iris, the patient is said to have narrow angles.
YLI involves creating a tiny opening in the peripheral iris, allowing aqueous fluid to flow from behind the iris directly to the anterior chamber of the eye. This typically allows an opening up of the angle of the eye. The narrow or closed angle thus becomes an open angle.
The procedure itself is completed with the patient seated at the laser, and requires no sedation. Topical anaesthesia eye drops are instilled, a lens is placed on the eye to better control the laser beam. In general, only a few very brief episodes of slight discomfort are associated with this procedure. However, generally there is no pain involved post operatively. The entire procedure takes only a few minutes.
