The retina is a very important aspect to eye function. It is able to capture images from the eye and send them forward to the brain to analyze. A retina evaluation can be done with a complete examination of a dilated eye along with using advanced imaging techniques to distinctively see the retina. The present techniques to remedy retina-related issues are touchy and require an experienced eye doctor in Laguna Hills, with an expert hand, to perform the procedures correctly.
Learn about Common Retina Diseases:
Diabetic retinopathy is when the retina is damaged by diabetes complications and this can eventually end in blindness. It may develop in patients who have type 1 or type 2 diabetes. The possibility of developing diabetic retinopathy is heightened with a prolonged case of diabetes. Diabetic retinopathy is characterized by the presence of abnormal blood vessels developing in the eyes that cause an irregular drainage and distribution of fluid in the eyes.
Diabetic retinopathy has the following symptoms:
- Vision obstructed by floaters
- Vision blurred
- Changes in vision
- Blind spots
- Loss of vision
- Color perception is off
- Diabetic retinopathy usually affects both eyes
Diabetic retinopathy may be categorized as early retinopathy or advanced retinopathy, this all depends upon signs and symptoms that are evident.
Treatment and Drugs
Treatment for diabetic retinopathy depends on the type of condition, the severity of the condition and how the condition previously responded to earlier treatments. There are many treatment options for diabetic retinopathy, these can include:
- Focal laser treatment – this can be used to handle leakage of blood and fluid in the eye.
- Scatter laser treatment – this shrinks the abnormal blood vessels.
- Vitrectomy - this removes blood from the middle of the eye.
- Eye injections - apply medication into the vitreous fluid in the eye.
Age-Related Macular Degeneration
A deterioration of the macula is known as an age-related macular degeneration. This condition is also known as AMD and is directly the cause for central vision. This normally only affects patients 50 years or older and is a major source of vision loss in older adults.
How can AMD be detected?
A person can actually show no indications or symptoms when in the early and intermediate stages of AMD. Only a very thorough eye exam will be able to identify its existence. There many aspects to the eye exams done to discover the early stages of AMD, these include the following procedures:
- Visual acuity test - to measure sight at a distance
- Dilated eye exam - to allow the doctor to get a better look at the back of the eye
- Amsler grid - to detect how vision may be altered
- Fluorescein angiogram – to detect abnormal blood vessels the doctor uses dye and special imaging techniques
Dry MD is what most beginning forms of AMD are considered. It causes blurred central vision in the affected eye and is caused when the cells sensitive to light in the macula gradually break down. A patient will tend to notice a blurred spot in the center of their vision as this condition worsens.
Vision can actually be lost on a gradual basis over time because the macula functions decrease.
Wet AMD is much more sever than dry AMD and affects approximately 10 percent of remaining patients with AMD.
When the macula starts to have abnormal blood vessels growing underneath it the condition of Wet AMD is present. These blood vessels can be delicate and tend to frequently leak blood and other fluid. This can cause quick and harmful damage to the eye because the resulting leakage causes the macula to swell.
If it is diagnosed prior to the severe vision loss, our Atlantis Eye Care specialists are able to stop the progression toward a person losing their central vision.
What are the symptoms of Wet AMD?
Straight lines in a person’s vision can appear wavy in the beginning stages of wet AMD. A person can also acquire a blind spot that develops in a loss of central vision.
You should contact your eye doctor immediately if you notice any of the above symptoms or any sort of vision changes. It is vitally important to treat an eye condition before any sever vision loss starts taking place.
Wet AMD Treatments
Early detection and diagnosis is vital with Wet AMD. It is the only way to temper, slow down and halt the progression of the disease and in turn preserve your vision. The symptoms of Wet AMD can be successfully managed with early detection. The following are treatments for Wet AMD but are not cures:
- Drug injections - can help to to slow the progression of wet AMD.
- Photodynamic therapy - destroys abnormal blood vessels. It uses focused light along with injected drugs. This technique has the possibility to restore vision where it has been lost before.
- Laser surgery - applies a laser directly against abnormal blood vessels to destroy them. This is a less common treatment and it carries the risk of also harming the surrounding healthy tissue.
