Understanding Retinal Detachment

Bothered by the sudden appearance of floaters? Troubled by hazy vision? Check with your doctor fast. You could be suffering from a retinal detachment that can make you blind!

The retina is a thin membrane attached to the back of the eye. It carries specialized sense receptors that make vision possible. These retinal cells are known as rods (which register black and white only) and cones (which react to color). A person has about 10 million cones and 100 million rods on the retina of each eye.

To work properly, the retina gets oxygen and nutri¬ents from underlying blood vessels. If it separates from this layer of blood vessels, the problem is called a retinal detachment.

Retinal detachment affects 20,000 people yearly in the United States alone. It may follow an injury to the eye, cataract surgery or severe nearsightedness. More men than women develop this condition and the risk increases in people with tumors of the eye and hyper¬tension. A genetic factor may also be involved as the condition tends to run in families.

“Retinal detachment is a medical emergency, and time is critical. Unless the detached retina is promptly surgically reattached, this condition can cause permanent loss of vision in the affected eye,” according to the Mayo Clinic.

“The condition is painless. However, symptoms almost always appear before the retina detaches. As the vitreous fluid (the jellylike substance inside the eyeball) shrinks and sags, it may tug on the retina, producing the sensation of flashing lights. If the tugging is strong enough and causes a retinal tear, small blood vessels will be damaged, allowing blood to seep into the vitreous and causing hazy vision and the sudden appearance of new floaters (dark or light spots or specks or lines in the field of vision),” said Dr. David E. Larson, editor-in-chief of the “Mayo Clinic Family Health Book.”

Whether or not surgery will help depends on the patient’s case. If the retina is merely torn but has not yet detached from underlying blood vessels, the physician can repair the damage by laser treatment (photocoagulation) or cryopexy (in which intense cold is applied to form a scar and hold the retina in place). Both can be done on an outpatient basis.

Surgery is necessary if the retina is detached but this should be done quickly since rods and cones die if they are separated from their source of nourishment for a long time. Once this happens, the patient becomes blind and nothing can restore his or her vision.

“Doctors commonly use one of three surgical procedures to repair a retinal detachment. Some of these procedures are done in conjunction with photocoagulation or cryopexy. The purpose of these treatments is to close any retinal holes or tears and to reduce the tug on the retina from a shrinking vitreous. The type, size and location of any retinal detachment will determine which procedure your eye surgeon recommends. In general, these surgeries can successfully treat more than 90 percent of cases of retinal detachment, although a second treatment is sometimes necessary,” concluded the Mayo Clinic.

Retinal Tear/detachment- Do’s and Don’s after laser correction. Lifting?

We were given very limited instructions after my husband had laser surgery to prevent further tearing and detachment of the retina monday. The instructions were simply no sports, no horseback riding, nothing that would jar your head, and no contacts for the first week.

I had the same situation. Had a retinal hole in one eye with partial detachment and a hole with no detachment in the other eye. Had both corrected with laser surgery. Was never told of any limits regarding lifting. I do know there are many more limitations when one has a full detachment that is treated through more invasive means. While I don’t think you would need to worry (I had a toddler at the time and am certain I lifted him that day) about lifting with laser surgery, it never hurts to call the doc’s office to check. I would not put drops in my eyes for a week unless the doc gave them to me. Tylenol or other pain reliever helped with the uncomfortaable feeling after the surgery.
