To make us understand better, our school teachers taught us how our eye functions like a camera and the retina acts like a film. What she meant to say is that retina is a light sensitive tissue, which reacts to incoming light and sends the image to the brain through the optic nerve.
It is obvious that any problem in the retina would disrupt the picture formed. So, one must get their eyes tested to ward off experiencing black spots, flashes of light or distorted or blurred vision. These problems could indicate eye ailments like diabetic retinopathy, retinal detachment or a torn retina.
If you have been experiencing any such symptoms, you must not ignore them. These could be assign of sever eye troubles. You must know when you need to consult an ophthalmologist to maintain healthy eyes.
When you suffer from diabetes, you are at a greater risk of developing cataracts, glaucoma, and most the very dangerous- diabetic retinopathy. Irregular sugar levels in body damage the blood vessels inside the eye causing diabetic retinopathy.
When blood vessels in the retina are damaged they may leak blood and grow fragile, brush-like branches and scar the tissue. This can blur or distort the vision.
If one is to observe the leading cause of blindness all over the world, the answer has to be diabetic eye problems. If you suffer diabetes and do not get proper treatment for it, you are more likely to go blind than the general population. The duration of diabetes is directly proportional to the risk of developing diabetic retinopathy.
Myopia, or short sightedness, is a very strong risk factor for retinal detachment. Retinal detachment occurs when the retinal tissue separates from the layer of blood vessels. The function of these blood vessels is to provide nutrients and oxygen. The lack of oxygen in cells results into the eye creating a blurred picture.
While the initial detachment could be restricted, if left untreated for a long time, it can cause blindness in the affected eye. Retinal detachments are also caused by trauma to the head or eye. According to the statistics, these are frequent in the elderly and middle aged people.
Kids below the age of 6 can develop retinoblastoma- the most common type of rapidly developing cancer of the retina. It could be heritable or non-heritable, may occur in one (unílateral retínoblastoma) or both the eyes (bílateral retínoblastoma). In some rare cases, a kid may develop trilateral retinoblastoma where the pineal gland is also affected along with both the eyes.
If you notice white spots on the pupil, redness and pain in your kid’s eyes, must take them to the doctor immediately. Children with cross eyes are at higher risk and must be tested regularly. If left untreated, the tumour can spread to the child’s lungs, brain and bones. The kid can even become blind.
Eyes are often neglected especially when we spend hours straining our eyes in front of the screen - computer or smartphones. We also do not realise the harm that other health problems do to our eyes. This negligence can cause blindness or vision impairment in the long run. Get your eyes checked regularly.
