Examination Initial Visit. Your initial visit to our office may take 1 to 3 hours, depending upon the type of retinal problem you have and the need for specialized tests such as fluorescein angiography, ophthalmic ultrasound, and optical coherence tomography. To examine your retina it will be necessary to place dilating drops in your eyes.

The OptiGen prcd -PRA Test Code 105 The OptiGen prcd-PRA Test. The OptiGen prcd-PRA test is a DNA-based test that helps you avoid one form of Progressive Retinal Atrophy (PRA). PRA refers to a group of diseases that cause the retina of the eye to degenerate slowly over time.The result is declining vision and eventual blindness.he OptiGen prcd test is done on a small sample of blood from the dog. The test analyzes the specific DNA mutation causing prcd-PRA. The OptiGen test detects the mutant, abnormal gene copy and the normal gene copy.

Overview Retinoblastoma most commonly affects young children, but can rarely occur in adults. Your retina is made up of nerve tissue that senses light as it comes through the front of your eye. The retina sends signals through your optic nerve to your brain, where these signals are interpreted as images.

Diagnosis To prepare for a retinal exam, your eye doctor puts drops in your eyes to open your pupils wide (dilate). This makes it easier to examine the back of your eyes (retina). Using a slit lamp or a special device called an ophthalmoscope, your eye doctor can examine your lens for signs of a cataract.

Retinoschisis Retinoschisis means splitting of the eye's retina into two layers. There are two forms of this disorder. The most common is an acquired form that affects both men and women. It usually occurs in middle age or beyond, although it can occur earlier, and it is sometimes known as senile retinoschisis.

What will you see in an OCT scan from our Lantana, FL eye doctor? With an OCT scan, doctors are provided with color-coded, cross-sectional images of the retina. These detailed images are revolutionizing early detection and treatment of eye conditions such as wet and dry age-related macular degeneration, Glaucoma, Retinal Detachment and Diabetic Retinopathy. An OCT scan is a noninvasive, painless test.

Diagnosis Optical coherence tomography. Your eye doctor may request an optical coherence tomography (OCT) exam. This imaging test provides cross-sectional images of the retina that show the thickness of the retina, which will help determine whether fluid has leaked into retinal tissue. Later, OCT exams can be used to monitor how treatment is working.

Retinal Detachment - Topic Overview The retina is a thin membrane of nerve tissue that lines the back of the eye. When part or all of the retina comes off (detaches from) the back of the eye, it is called retinal detachment. The nerve cells in the retina normally detect light entering the eye and send signals to the brain about what the eye sees.But when the retina detaches, it no longer works correctly.hen part or all of the retina comes off (detaches from) the back of the eye, it is called retinal detachment.

What Your Eyes Say About Your Brain Pencil in the eye doctor. Even if you’re blessed with 20/20 vision, retinal imaging (a fancy term for the photo eye docs take of your eyes) does far more than test vision: It could be the easiest way yet to check in on your brain.

- A positron emission tomography (PET) scan is an imaging test that allows doctors to check for disease in your body. The scan uses radioactive tracers in a special dye. These tracers are injected into a vein in your arm and are then absorbed by your organs and tissues.

Retina Scanner Retina Scanner is an great app for fooling your friends. Here is how it works. Secretly, you enter your friend's information like name, age, gender blood group in the first screen. Ask your friend to put his/her finger on scan button and hold the phone in front of their eye so that it works as a eye scanner.

Why does a retina display matter? What Retina means. When Apple talks about a Retina display it's not referring to a worldwide standard or a set of specifications. It's actually just a marketing term, and it simply means that the screen has sufficient pixel density, so that when you look at it normally, you can't make out all the individual pixels.

What is a Retina Specialist? A retina specialist is an ophthalmologist who has received special training in conditions which involve the vitreous body and retina of the eye. This subspecialty of ophthalmology is sometimes known as vitreoretinal medicine.

Adult health During a traditional eye exam, an eye doctor dilates your eyes with special eyedrops and then checks your retinas for abnormalities using tools such as an ophthalmoscope — a lighted magnifying instrument. During a laser retina scan, such as Optomap, your eyes may or may not be dilated.

Retinal cryopexy Retinal cryopexy. Definition. Retinal cryopexy, also called retinal cryotherapy , is a procedure that uses intense cold to induce a chorioretinal scar and to destroy retinal or choroidal tissue. Purpose. The retina is the very thin membrane in the back of the eye that acts like the film in a camera. It is held against the inside back portion of the eye by pressure from fluid within the eye. In the front part of the eye, the retina is firmly attached at a ring just behind the lens called the pars plana.

What you need to know about a detached retina Causes. The retina is the layer of tissue that lines the inside of the eye. It is light sensitive and its function is to send visual signals to the brain, through the optic nerve.

Retinal Detachment - Topic Overview The retina is a thin membrane of nerve tissue that lines the back of the eye. When part or all of the retina comes off (detaches from) the back of the eye, it is called retinal detachment. The nerve cells in the retina normally detect light entering the eye and send signals to the brain about what the eye sees.But when the retina detaches, it no longer works correctly.he most common cause of a tear is posterior vitreous detachment (PVD). Vitreous gel fluid flows through the tear, pools beneath the retina, and lifts the retina off the back of the eye. Retinal detachment can also happen without a retinal tear. Scar tissue buildup in the eye may pull on the retina.

Diabetic eye screening Diabetic eye screening. Diabetic eye screening is a key part of diabetes care. People with diabetes are at risk of damage from diabetic retinopathy, a condition that can lead to sight loss if it's not treated. Diabetic retinopathy is one of the most common causes of sight loss among people of working age.

Detached Retina: Causes, Symptoms and Treatment Detached Retina: Causes, Symptoms and Treatment. A detached retina, which occurs when the retina becomes separated from the tissue which normally supports it, is an extremely serious eye condition which must be treated as a medical emergency. The retina is the very thin sensory membrane which lines the back of the eye and is only about the size of a postage stamp.
