What is the retina?
The retina is a very thin layer and the light sensitive layer the coats the eye from inside, When light enters the eye, it is focused through the cornea and the human lens to fall on the retina which turns it into electrical impulses to be sent to the brain through he optic nerve and translated into a picture.

The retina is composed of two major parts: the macula that is responsible for the visual acuity, and the peripheral retina that enables a person to see sideways. The retina is surrounded from the outside with a layer called the choroid, and is rich in blood vessels to provide nutrients to the retina.

What is retinal detachment?
It happens when the retina is detached from the choroid and loses its nutrient supply. When it is detached completely, it loses its ability to conduct electricity to the brain; and here the eye loses the ability to see. The longer the duration of detachment, the more the atrophy that affects the retina, which is why it is very important to reposition the retina as soon as possible.

What are the causes of retinal detachment?
It is a serious condition that affects 1 in 10,000 people, and it is often seen after the age of 40 due to affection of the retina by advancing age, also high myopia is a risk factor, or after eye trauma or eye surgery, severe inflammations or eye tumors, and persons with severe diabetic complications. The risk increases in patients with relatives who had retinal detachment.

How does retinal detachment happens?
With advancing age, shrinkage of the vitreous ( the gel filling the eye ), which is in front of the retina, usually doesn’t cause any harm. In some cases, a tear in the retina accompanies this shrinkage especially where it is attached to the retina. This usually doesn’t affect vision, especially if this happens in the retinal periphery. But failure to treat this tear early leads to sub-retinal accumulation of fluid from the vitreous, causing the retina to detach and fail to perform its job as it should.

What are the symptoms of retinal tears and retinal detachment?
It can happen without symptoms but the patient can experience sudden flashes or floaters due to hemorrhage from the tear. You need to be reminded that flashes and floaters by itself does not mean you have a tear, but that you need to be checked by an ophthalmologist to ensure integrity of the retina.

Symptoms also include the patient experiencing waviness of the image or clouding or veil in front of the eye. And if the detachment affects the macula, it could lead to rapid deterioration of vision with retinal detachment, which could lead to complete loss of vision if left without a treatment for a long period of time.

How can retinal tears or retinal detachment be diagnosed?
When a person have these symptoms, he needs to go immediately to the ophthalmologist to be examined with advanced devices that help him diagnose such condition such as fundus examination or ultrasound.

How can retinal tears or retinal detachment be treated?
Retinal tears are treated using laser or cryo ( freezing ), while the retinal detachment needs surgical intervention for removing the fluid that accumulated under the retina, and the eye n=might be surrounded with a special band that is stitched in place around the eye to help re-position the retina.

Retinal detachment surgery can be done under local or general anesthesia and the operation can need a recumbency period from 4-6 weeks.

The patient should be aware that the surgery can lead to restoring vision when it is treated early, but sometimes the vision may not optimal after surgery due to many factors; such as the period between the detachment and doing surgery, the site of detachment and whether it was a partial or a complete detachment.

Remember:
Regular examinations are recommended if you have high myopia or you have a relative with retinal detachment.
If you develop flashes or floaters, you should see an ophthalmologist soon for early discovery of tears and detachments, which helps optimal restoration of vision after surgery.
