![]() ![]() This can be seen through a standard optical coherence tomography (OCT) that. A unique feature of this central pit is the displacement of other retinal components to create space for cones. Its about 1.5 mm in diameter and contains about 199,000 cones/mm squared. If you are concerned about either diabetic or hypertensive retinopathy, please call (508) 238-2388 to arrange for a comprehensive eye examination at Easton Eye Consultants. The central fovea appears as a small flat spot at the retinas center. This treatment, called Pan Retinal Photocoagulation or simply PRP, can preserve most of your vision, but loss of side vision and reduction in night and color vision may result. We’ll look at the OCT through a number of common diseases. Two or more sessions are needed to place the one to two thousand laser spots in the areas of the retina away from the macula, which cause the abnormal blood vessels to shrink. There are fewer variations in the appearance of the sclera than in any of the other tissues of the fundus. View of the normal retina with OCT The macular OCT can be used to evaluate the premacular vitreous, macula, and choroid. If the disease advances to the proliferative stage, it can be treated with laser surgery. Until the disease reaches its most severe stage, it is sometimes enough to manage retinopathy by controlling the blood pressure, blood cholesterol, and blood sugar levels. The earlier stages of the disease do not normally require treatment, but annual or more frequent examinations should be considered to monitor the progress of the disease. Hypertensive retinopathy has relatively few hemorrhages and a greater number of “cotton wool” spots than diabetic retinopathy, although there is little to differentiate the two for the patient. Hypertensive retinopathy and diabetic retinopathy, while being similar in some features, show up differently on the retina. Hypertensive retinopathy, which can be determined during a comprehensive eye exam at Easton Eye Consultants, may be the first sign of hypertension, and occurs mostly among those middle-aged or older. This includes a brown to slate gray coloration with distinct but mildly. ![]() Close to half the population who have been diagnosed with diabetes will have some stage of diabetic retinopathy. Many nevi can be identified by their appearance alone on examination of the retina. Retinopathy can accompany either hypertension or diabetes (either type 1 or type 2). Macula The area of the retina at the posterior pole of the eye responsible for. Very Severe Non-Proliferative Diabetic Retinopathy structures of the normal eye and to perform a basic eye examination. While the presence of retinopathy may not be evident at first, over time it can worsen and lead to loss of vision.Īdvanced Proliferative Diabetic Retinopathy The blood vessels may swell and leak fluid, or abnormal ones may grow over the surface of the retina and interfere with proper vision. Method Of Exam Keep both yours and the persons eyes Have the patient focus on a distant object Look at right fundus with your right eye Ophthalmoscope. Retinopathy refers to a disease of the blood vessels within the retina that causes and changes their size and nature. ![]()
