The retina does not function properly when it is detached, resulting in seeing a peripheral shadow that can progress to cause significant blurring of the vision.
A retinal detachment is a medical emergency and very serious. Evaluation and treatment are needed urgently as it can permanently damage your vision if the detachment is not repaired within 24 - 72 hours.
Normally, as the eye moves, the vitreous moves around within the eye without causing any problems with the retina.
However, occasionally the vitreous can pull on the retina and create a tear or rip.
When that happens, fluid can enter through the tear and lift (detach) the retina off the back wall of the eye.
Dr. Jonathan Staman explains how the eye works to a patient.
Without timely treatment, permanent vision loss can result. Call your eye doctor right away if you have any of the following symptoms:
Flashing lights such as seeing stars similar to being hit in the eye.
New or an increase in floaters. These can look like specks of dust, lines, mosquitos/flies or cobwebs in your field of vision.
A shadow or grey curtain appearing in your peripheral (side) vision.
After your pupils are dilated, your doctor may perform a slit lamp evaluation. Special lenses are placed between the slit lamp and the cornea (or directly on the cornea) to view deeper structures of the eye, such as the optic nerve, retina, and the area where fluid drains out of the eye (drainage angle).
A camera may be attached to the slit lamp to take photographs of different parts of the eye. This will allow your eye doctor to also examine your peripheral retina, which is where most detachments are located.

There are several ways to fix a retinal detachment:
This procedure can be performed in the office.
Your retinal specialist places a gas bubble inside your eye to act as a splint to support the retina so it can heal properly.
Afterwards, you will need to keep your head positioned in a certain way for a few days in order to keep the bubble in the right place. As your eye heals, the gas bubble goes away on its own over a few weeks.
Vitrectomy Surgery. This procedure is performed in the operating room.
Your retinal specialist removes the vitreous gel from the eye to stop the pulling on the retina.
A full gas or oil bubble will be placed in the eye to support the retina like a cast or splint so it can heal properly. The gas bubble dissolve over a few weeks. However, if an oil bubble is needed, your surgeon will need to remove it a few months later.
If you have a gas bubble, you cannot fly in an airplane because the altitude changes cause the gas to expand and increase the eye pressure and result in permanent loss of vision.
Scleral Buckle. A silicone band of soft plastic is attached to the outside of your eyeball behind the eyelids. It gently indents the eye inward to prevent the pulling of the vitreous gel on the retina.
The following is a list of possible surgical risks:
Your surgeon will discuss the risks and benefits of surgery.
You might have some pain for a few hours after surgery. You will be given pain medicine to help you feel better.
You need to rest and be less active after surgery for a few weeks. Your ophthalmologist will tell you when you can exercise, drive or partake in other activities.
You will need to wear an eye patch after surgery. Be sure to wear it as long as your doctor tells you to.
If a bubble was put in your eye, you will need to keep your head in one position for about 1 - 2 weeks. Your doctor will tell you what that position is. It is very important to follow the directions so your eye heals.
You might see floaters and flashing lights for a few weeks after surgery. You may also notice the bubble in your eye. Over time, this bubble will decrease in size and may actually break into smaller bubbles.
Your sight should begin to improve about four weeks after surgery. It could take months after surgery for your vision to stop changing. It is possible that the healing process following surgery could take a year or more.
You may see flashing lights or many new floaters.
You may see a shadow in your side vision.
Also, a gray curtain might cover part of your field of vision.
If you have any of these signs, call an ophthalmologist right away.
A detached retina must be treated immediately to keep your vision.
Retina: Layer of nerve cells lining the back wall inside the eye. This layer senses light and sends signals to the brain so you can see.
Vitreous: Jelly-like substance that fills the middle of the eye.
Floaters: Tiny clumps of cells or other material inside the vitreous. These look like small specks, strings or clouds moving in your field of vision.
