Detached Retina – Overview
A detached retina is a serious eye condition where the retina—the thin layer of tissue at the back of the eye—pulls away from its normal position. This separation cuts off the retina’s supply of oxygen and nutrients, which can result in permanent vision loss if not treated promptly. A detached retina is considered a medical emergency and requires immediate attention from an ophthalmologist.
The retina plays a vital role in vision. It captures light and converts it into electrical signals sent to the brain via the optic nerve. When the retina detaches, this process is disrupted, causing blurred vision, flashes of light, floaters, or a shadow across the field of vision. If left untreated, the condition can lead to total blindness in the affected eye.
Retinal detachment most commonly occurs due to ageing, injury, or underlying eye diseases. The condition affects about 1 in 10,000 people each year, often in those aged 50 and older. However, younger individuals with high myopia (short-sightedness), a family history of retinal problems, or those who have had previous eye surgery are also at increased risk.
Detached Retina
There are three main types of retinal detachment: rhegmatogenous (caused by a tear or hole in the retina), tractional (where scar tissue pulls the retina away), and exudative (caused by fluid build-up beneath the retina without a tear). Each type requires different treatment approaches.
In summary, a detached retina is a potentially sight-threatening condition that demands swift diagnosis and surgical intervention. Early recognition of symptoms and access to professional care significantly improve the chances of preserving vision.
