![]() ![]() If not treated promptly, retinal problems can lead to permanent vision loss. Certain diseases or trauma to the eye can cause scar tissue to form and pull on the retina. Causes: As you age, the vitreous gel in your eye liquefies and shrinks, causing the retina to tear or detach.Symptoms: flashes and floaters in which you experience cobwebs or speck-like floaters in the field of vision, they are usually black and float in and out of view.Īnyone can have a tear or detachment but higher-risk factors include family history of vitreo-retinal problems, age, cardiovascular disease or diabetes, nearsightedness, previous eye surgery or trauma to the eye.There is no way to tell if a PVD caused a retinal tear so anyone experiencing symptoms needs a prompt dilated retinal exam. Retinal tears can lead to a detached retina if the tear is not treated. There is a small chance that a PVD can cause a retinal tear. The vast majority of PVDs do not cause serious problems, but many people notice annoying floaters and occasional light flashes. PVD occurs when liquefaction progresses until the vitreous separates from the retina. Prevention: regular eye exams, diet, medications, regular exercise, blood sugar and blood pressure control, and avoidance of alcohol and cigarettes.Treatment options: laser photocoagulation to control leaking capillaries and prevent growth of new capillaries, vitrectomy to remove cloudy vitreous and scar tissue, and cryotherapy to shrink capillaries and repair the retina.Risk factors: high blood pressure, smoking and high cholesterol.What are the symptoms For most people, vision. Symptoms: blurry, darkened or cloudy vision seeing floaters or black lines However, if the scar tissue has formed over the macula, our sharp, central vision becomes blurred and distorted.Common Retina Conditions Diabetic Retinopathyĭiabetic Retinopathy occurs when diabetes damages blood vessels inside your eye, which can lead to blurry, distorted vision and blindness. If you are experiencing vitreo-retinal problems you should consult with a specialist that focuses on diseases in the back of the eye such as macular degeneration, diabetic disease, retinal detachment, trauma and intraocular infection. small lesions called histo spots can occur that might lead to growth of new blood vessels and scar tissue in the retina. Damage to the retina may be caused by injury, illness or as a result of aging. Eye researchers taking part in the SST investigated the benefits and risks of retinal surgery to remove lesions consisting of new blood vessels, scar tissue, and associated bleeding in different groups of patients. When the retina is damaged in any way, your vision becomes impaired. Like the film of a camera, it receives images projected through the lens of the eye and sends these images to your brain through the optic nerve. Other terms for this scar tissue are epiretinal membrane (ERM) or cellophane maculopathy. The retina is the delicate, light-sensitive tissue that covers the interior wall of the eye. What is macular pucker A macular pucker is a wrinkling of your retina due to scar tissue.
