Retinal Detachment Tear, Peripheral Photocoagulation (4K)

Описание: I went in for a followup eye exam and found a problem that had to be corrected before any further cataract surgery could be considered.


From UCLA Health website “After the age of 50, about 40 percent of the population already has a vitreous detachment. The more nearsighted the person is, the higher the chance for them to have this condition happen to them,” says Gad Heilweil, MD, an ophthalmologist at Doheny Eye Center UCLA.

Per Pradeep Prasad, MD, at UCLA Stein Eye Institute. As people age, the gel-like vitreous in the eye begins to liquefy and contract, peeling away from the retina. This can lead to a retinal tear or detachment. It can be vision-threatening and requires urgent medical attention. “It’s impossible for a patient to be able to distinguish between a vitreous detachment, which is bothersome, and an associated tear or detachment,” Dr. Prasad said. It is important to see an ophthalmologist.

When to see a doctor
Seek immediate medical attention if you are experiencing the signs or symptoms of retinal detachment. Retinal detachment is a medical emergency in which you can permanently lose your vision.

Causes
There are three different types of retinal detachment:
Rhegmatogenous (reg-ma-TODGE-uh-nus). These types of retinal detachments are the most common. Rhegmatogenous detachments are caused by a hole or tear in the retina that allows fluid to pass through and collect underneath the retina, pulling the retina away from underlying tissues. The areas where the retina detaches lose their blood supply and stop working, causing you to lose vision.
The most common cause of rhegmatogenous detachment is aging. As you age, the gel-like material that fills the inside of your eye, known as the vitreous (VIT-ree-us), may change in consistency and shrink or become more liquid. Normally, the vitreous separates from the surface of the retina without any complications — a common condition called posterior vitreous detachment (PVD). One complication of this separation is a tear.
As the vitreous separates or peels off the retina, it may tug on the retina with enough force to create a retinal tear. Left untreated, the liquid vitreous can pass through the tear into the space behind the retina, causing the retina to become detached.
Tractional. This type of detachment can occur when scar tissue grows on the retina's surface, causing the retina to pull away from the back of the eye. Tractional detachment is typically seen in people who have poorly controlled diabetes or other conditions.
Exudative. In this type of detachment, fluid accumulates beneath the retina, but there are no holes or tears in the retina. Exudative detachment can be caused by age-related macular degeneration, injury to the eye, tumors or inflammatory disorders.

Risk factors
The following factors increase your risk of retinal detachment:
Aging — retinal detachment is more common in people over age 50
Previous retinal detachment in one eye
Family history of retinal detachment
Extreme nearsightedness (myopia)
Previous eye surgery, such as cataract removal
Previous severe eye injury
Previous other eye disease or disorder, including retinoschisis, uveitis or thinning of the peripheral retina (lattice degeneration)
