![]() How retinal detachment causes blindness?Ī retinal detachment condition may lead to permanent blindness when the condition is not treated or prevented in time. Patients are therefore recommended to visit their eye doctors regularly when they start experiencing retinal detachment symptoms. On the other hand, in retinal detachment ultrasound, the doctor is interested in investigating the presence of vitreous fluids. ![]() In the retinal examination, the doctor uses high light to illuminate the back of the eye, including the retina, to get a detailed view of the retina, areas where detachments occurred and the presence of inflammation or retinal joles. The doctor may diagnose a retinal detachment through either retinal detachment examination or retinal detachment ultrasound. The patient underwent previous medical surgery.Medical diagnosis indicates extreme myopia or shortsightedness.The medical history indicates a previous history of retinal detachment.The patient has a medical history of a previous diagnosis of retinal detachment.The following are the primary risk factors for retinal detachments The primary causes for exudative detachments include inflammatory infectious and neoplastic conditions with the choroid or the retina. Lastly, exudative retinal detachment describes a condition where fluids fill subretinal space, pushing it away and may lead to a buildup of fluids inside the blood vessels and even swelling of the eye. The most common cause of tractional retinal detachment is diabetes and prolonged high blood pressure. When the force pulling the retina is high enough, it can separate the neurosensory nerve from the attached retina. In addition, tractional retinal detachment describes the proliferation of the membranes that make up the vitreous retinal surface pulling the retina from the neurosensory retina. The common cause for rhegmatogenous retinal detachment is ageing, as the vitreous changes its composition in old age. When this happens, the detached vitreous enters the space beneath the neurosensory retina leading the retina detachment, retinal injury or inflammation. The rhegmatogenous retinal detachment describes a condition arising from retina dialysis, retinal break or retinal hole forming within the tissues that make up the retina. The three primary retinal detachment types are rhegmatogenous, tractional and exudative detachments which have different causes depending on the type. A curtain-like shadow blocks the eye's vision on the peripheral field.Overtime there is a gradual deterioration of peripheral vision evident in a grey curtain.The patient experiences flashes of light in the affected eye.The eye appears to have many floaters, tiny specs drifting away from the peripheral view/field of vision.What are the Symptoms of Retinal Detachment? Figure 2: Field of vision for an individual with retinal detachmentĪccording to Mayo Clinic, the following are the symptoms of retinal detachment ![]() In addition, the condition is particularly common in South East Asia and most European countries. The study also shows that males are highly susceptible to the condition than females. Incidences of retinal detachment are very rare in individuals, with studies showing that it affects 1 to 17 individuals out of every 10000. When retinal detachment happens, the retina pulls away from the supporting tissues causing reduced vision and, when not treated, may cause blindness. Pigment epithelial detachment means that the thin retina tissue is pulled away from the different layers of the eye tissues (see figure 1 above). The retina sends these signals to the human brain for visual recognition. The retina's primary purpose is to receive light and convert it to neural signals. What are Retina and Retinal Detachment? Figure 1: Retinal Detachment ConditionĪ retina describes the thin layer of tissue found near the optic nerve at the back of the human eye. First, let us see what’s retinal detachment and the signs of retinal detachment. This article will discuss various retinal detachment surgeries, how to prevent retinal detachments in daily life, and how low vision aids help with retinal detachment prevention and post-retinal detachment surgery recovery. Retinal detachment surgery has a high success rate in restoring an individual's vision and helps prevent further retina detachment. The appropriate recommendation would be to undergo retinal detachment surgery. Retinal detachment disrupts the retina's normal function, leading to low vision and sometimes causing blindness. ![]()
