The retina is the light-sensitive membrane inside the eyeball located right at the back. It acts as a screen where the lens focuses the image. The responsibility of the retina is to convey the image signal to the brain via the optic nerve.
Retinal detachment refers to the situation where the retina separates from the back of the eye. It can lead to partial to complete loss of vision. It is a medical emergency. When left untreated, it can lead to a permanent impairment of vision.
When should you worry about retinal detachment?
Retinal detachment can happen to anyone of any age. Some types are more common in the elderly than others. However, knowing the symptoms can help you and your dear ones protect their eyesight with timely diagnosis and treatment.
If you experience any of the following symptoms, consult an eye specialist immediately –
● Blurred vision
● Sudden flashes of light when you look to the sides
● Partial loss of sight. (it may appear as a curtain across your field of view that feels like a shadow)
● The sudden presence of multiple floaters (small debris floating across your field of vision)
What are the different types of retinal detachment? What are its causes?
There are three types of retinal detachment, each with different causes and effects. Exploring the various reasons can help you understand why contacting the best cataract surgeon in Delhi is necessary to preserve and restore your vision –
i. Rhegmatogenous retinal detachment: In the case of rhegmatogenous retinal detachment, there is a hole in the retina. It allows fluid to enter behind the retina. The liquid layer can separate the retina from the retinal epithelium. This type of retinal detachment can deprive the retinal cells of oxygen and nourishment.
ii. Tractional retinal detachment: Tissue from the surface of the retina contracts causing the retina to pull away from the back of the eyeball. It is typical in those with diabetes mellitus. The vascular damage can result in the formation of scar tissues in your eye. That can further exacerbate the loss due to retinal detachment.
iii. Exudative detachment: There are no tears or scar tissue formation in this type of detachment. Typically the following conditions lead to exudative detachment –
● Inflammatory diseases of the eye
● Coat’s disease (aberrant development of blood vessels behind the retina that results in protein build up behind the retina)
● Cancer behind the retina
Who is more at risk of developing retinal detachment?
Some people are more at risk of developing retinal detachment as compared to others. The risk factors include –
● Direct trauma to the eye
● Age (especially individuals over 50 years of age)
● History of retinal detachment
● Diabetes mellitus

What is the available treatment for retinal detachment?
Today, it is possible to revert retinal detachment. Bharti eye is the best eye hospital in Delhi for retina offers almost all of these corrective procedures, depending on the cause and risk factors involved.
Freeze treatment or laser procedure – it involves cryopexy or laser surgery. It is a simple process that is enough to correct a small hole or tear in the retina. A competent eye surgeon uses a medical laser or a freezing probe to seal the breaks in the retina.
Surgery – when a larger part of the retina is damaged, you might need surgery to reattach or move the retina. Operations are more elaborate than cryopexy or laser surgery and have a more extended recovery period.
Treatment for retinal detachment is especially effective upon early diagnosis. Sometimes more than one procedure is necessary. However, more than 90% of people recover completely after corrective surgery.
