A look into…Retinal Detachment
Retinal detachment (RD) occurs when the retina begins to pull away from the blood vessels at the back of the eye, which supply oxygen and glucose to the cells there. There are three different types of RD: rhegmatogenous retinal detachment, exudative retinal detachment and tractional retinal detachment. Rhegmatogenous RD is the most common type caused by retinal tears which allow fluid to leak through from the middle of the eye and build up under the retina pushing the retina away from its position. This may present itself as black specks floating across the eye, sudden short flashes of light in the eye or blurring of the vision. Retinal detachments are classified as a medical emergency, normally requiring surgery and therefore help must be sought immediately otherwise loss of vision can result.
Proliferative vitreoretinopathy (PVR) is a disease which develops as a complication of rhegmatogenous retinal detachment, occurring in 8-10% of patients undergoing primary RD surgery, hindering the successful surgical repair. Retinal detachments are also commonly linked to, or as a result of, cataract surgery, retinal breaks and lattice degeneration. The Epiomic™ database provides robust information about this disease area by sub-dividing the patient population by detachment type, clinical history and lens status.
Within the eye, diabetes can affect the retina causing diabetic retinopathy by causing the capillaries within the eye to become leaky, leading to fluid movement in the retina which results in swelling. This can lead to retinal detachment. Using accurate data sources, the Epiomic database provides you with a greater understanding of the co-morbidities of RD such as diabetes and sickle cell disease, which is crucial information for developing innovative treatments.
Did you know ... Retinal detachment is extremely common in those with severe or extreme myopia (short-sightedness) as the retina is stretched thin.
