Overview of Retinal Detachment
Retinal detachment usually causes over the age of 50 years due to weakness of the eye. This is the most common cause of retinal detachment.
Signs and Symptoms of Retinal Detachment
The retina is a light-sensitive membrane located behind the eye. The retina is responsible for focusing the image on the lens. When the retina changes the image to signals for brain detection, in that way, people can see the objects easily.
Retinal detachment (ankh ka parde ki alehdgi / آنکھ کا پردہ کی علیحدگی) is a condition in which the light-sensitive retinal layer of tissue (the retina) at the back of the eye pulls away from its normal position. The permanent vision loss may result if the retinal detachment is not treated on time.
Prevalence of Retinal Detachment
Globally, there are around 33%-44% of people experiencing retinal detachment due to various causes.

Types of Retinal Detachment
Retinal detachment is painless. The warning signs of retinal detachment appear until it becomes advanced such as:
- The sudden appearance of spots affecting the vision loss
- Flashes of light in one or both eyes (photopsia)
- Blurred vision
- Gradually reduced peripheral vision
- A curtain-like shadow over the visual field
Causes of Retinal Detachment
Retinal detachment comprises three main types, depending on its cause.
Rhegmatogenous Retinal Detachment
Rhegmatogenous retinal detachment is one of the most common types of retinal detachment. It is caused by a small tear in the retina. The fluid passes through the hole of the eye and gets back to the retina. This fluid detaches the retina from the retinal pigment epithelium (it provides nourishment and oxygen to the retina).
Causes of Rhegmatogenous Retinal Detachment
As the individual gets older, the risk of rhegmatogenous retinal detachment is higher.Changing the texture and shrinkage of the vitreous in the eye begins to form the tears in the retina that pulls from its normal position. Other causes are eye injuries, eye surgery, and nearsightedness.
Tractional Retinal Detachment
Tractional retinal detachment starts as the scar tissue on the retina pulls the retina away from the back of the eye.
Causes of Tractional Retinal Detachment
One of the most common causes of tractional retinal detachment is diabetes. Because high glucose levels damage the blood vessels and make a hole in the retina. From there, the retina becomes detached.
Other causes of tractional retinal detachment are eye diseases, eye infections, and swelling (inflammation) in the eye.
Exudative Retinal Detachment
Exudative retinal detachment results from the accumulation of fluid behind the retina, but there are tears or breaks in the retina. This leads to the retinal detachment.
Causes of Exudative Retinal Detachment
The most common causes of exudative retinal detachment are the leakage of blood vessels or cause swelling in the back of the eye.
Other causes of leaking blood vessels and oedema production in the back of the eye are as follows:
- Injury or trauma to the eye
- Age-related macular degeneration (AMD)
- Eye tumours
- Diseases cause the inflammation of the eye
- Coats disease, a rare eye disorder
There are the following factors increases the risk of retinal detachment:
- Aging over age 50
- History of retinal detachment in one eye
- Family history of retinal detachment
- Extreme nearsightedness (myopia)
- People had a history of eye surgery, such as cataract surgery
- Severe eye injury
- Other eye disease or disorder, including retinoschisis, uveitis or thinning of the peripheral retina (lattice degeneration)
There's no way to reduce the risk of retinal detachment until or unless people wear protective things such as safety goggles during the risky activities.
Another way to protect it is early diagnosis of an eye if people are doing dilated eye exams regularly or test for another eye disease. Early treatment can prevent them from permanent vision loss.
Treatment of Retinal Detachment | When to Consult a Doctor
Diagnosing the retinal detachment, an ophthalmologist conducts the following ways for the eye examination, which includes:
- Eye pressure
- The physical appearance of the eye
- Ability to see colours
An ophthalmologist may also check whether the retina is functioning properly or not. A doctor also examines the blood flow of the eye particularly in the retina.
Additional tests are the ultrasound of eyes to reveal any abnormalities in the eye via images of it.
