What's a detached retina and macular hole?

Retinal detachemnt. Retinal detachment is a detachment of the retina from the inside of the eye. The portion of retina that is detached leaves the vision completely black in the detached area. Retinal detachment is usually caused by a peripheral hole/tear of the retina. A macular hole is a hole in the center of the macula, the portion responsible for central vision causing varying degrees of loss.
Different disorders. Detached retina occurs in the periphery and can spread to involve the central vision, but sometimes are asymptomatic. Macular holes always cause symptoms of waviness, blind spots, or blurring. Both can be treated with retinal surgery. Macular hole closure rate is best when treated within the first 6 months of developing. There is a 10% risk of developing a hole in the second eye.
Big problem. A retinal detachment caused by a macular hole is a rare problem. It usually occurs in very nearsighted eyes (myopic). Fixing the macular hole fixes the detachment, but given the exact characteristics of such eyes make the fix difficult to achieve. Repairing the macular hole involves a vitrectomy surgery. Most of the times, macula holes occur without developing a retinal detachment.

Can you tell me about macular hole surgery on the eye?

Excellent surgery. Macular hole surgery is one of the great successes of modern ophthalmology. In good hands, it has a greater than 90% success rate at closing the hole, and most patients have good vision recovery. However, how good the vision will be after surgery is not predictable, and generally worse the longer the hole was present before repair. Not having surgery for a macular hole = bad idea.

Went to the eye dr. He said my vision was 20/400. What does that mean. I had macular hole surgery last year in my rt. Eye.

Poor eyesight. 20/400 vision means that you see at 20 feet what others can see at 400 feet. There are many people with 20/400 vision. However, they can be corrected to 20/20 with glasses or contacts. If your vision is 20/400 and cannot be corrected, it means you have poor eyesight and are legally blind.
