The retina is a thin layer of tissue in the back of the eye. This light-sensitive tissue converts light energy into impulses that travel to our brain via the optic nerve. The brain interprets these impulses into the images that we see. There are a number of diseases of the retina that we at Nightingale Eye Associates diagnose and treat.
Floaters are often described as specks, cobwebs, dots or other shaped spots that “float” through a patient’s field of vision. They are most apparent when looking at a blank background such as a blue sky. Floaters are the result of small condensations of the vitreous – a gel-like substance that fills your eye. Mild floaters are common with age and nearsightedness.
Floaters can often be accompanied by “flashes,” where a patient experiences a brief lightening-like flash in their peripheral vision. Flashes are due to the vitreous jelly pulling on the retina.
A sudden shower of many floaters accompanied by flashes can be an indication of more serious conditions like retinal tears or detachments. These symptoms require prompt attention. Please contact Nightingale Eye Associates to be seen within 24-48 hours if you are experiencing these symptoms.
Tears and detachments of the retina are a potentially vision threatening condition. Symptoms of this condition are an onset of flashes and floaters. If a retinal tear is diagnosed early, it can be treated with a quick in-office laser procedure to prevent any worsening. This laser procedure helps prevent the torn retina from detaching.
If a retinal tear proceeds to retinal detachment, surgery will often be needed to restore the position of the retina. Retinal detachments typically occur in patients over 40 with a history of extreme myopia, trauma or other eye disease. If you are experiencing any flashes or floaters, please contact Nightingale Eye Associates to be seen within 24-48 hours.
Macular degeneration, or AMD, is the leading cause of blindness in the U.S. for people over the age of 65. The macula is responsible for our central vision – the vision we use to read and see fine detail. AMD occurs when the macula deteriorates over time. When the macula fails to work properly, central vision becomes blurry making it difficult to read and see fine detail. AMD typically develops in some patients as they age, with genetics, smoking and some other factors having an influence.
There are two major forms of macular degeneration: dry and wet. Dry AMD is more common and typically has much less effect on vision. Wet AMD is less common but when it occurs it can have a greater impact on a patient’s vision. These two forms of AMD have different treatments. Therapies for both dry and wet AMD have seen a significant advancement in the last decade. At Nightingale Eye Associates, we have the most up-to-date diagnostic modalities for identifying patients who either have AMD or are at risk of developing AMD. If you are diagnosed with AMD, we will guide you through the appropriate treatment modalities.
Epiretinal membranes, or macular puckers, occur when a very fine cellophane-like membrane forms over the central retina (macula). These membranes can form spontaneously or they can be the result of other problems in the eye. Patients with significant epiretinal membranes can experience distortions in their vision or a general blurring of vision. Often, these membranes are so thin and insignificant that they cause no symptoms, in which case they can be followed over time for growth. If an epiretinal membrane becomes significant, we can offer surgery to remove the membrane and restore vision. Epiretinal membranes can be readily diagnosed on routine eye exams.
Retinal vascular diseases, such as retinal vein and artery occlusions, occur when blood flow to the retina is blocked, leading to vision loss. Retinal vein occlusion (RVO) happens when a vein in the retina is blocked, causing blood and fluid to leak into the retina. Symptoms include sudden blurred or partial loss of vision. Retinal artery occlusion (RAO) involves a blockage in a retinal artery, often leading to more severe, sudden vision loss. Both conditions are medical emergencies and can result from underlying issues like high blood pressure, diabetes, or cardiovascular disease. Treatment aims to manage the cause and minimize vision loss through medications, laser therapy, or injections. Early diagnosis is crucial to prevent permanent damage.
