scatter laser treatment - 

This is a kind of laser surgery for people with proliferative retinopathy. Scatter laser treatment helps to shrink the abnormal blood vessels. For this treatment, the doctor places 1000 to 2000 laser burns in the areas of the retina away from the macula. This causes the abnormal blood vessels to shrink. Because a high number of laser burns are necessary, a person who gets this treatment usually needs two or more sessions. Scatter laser treatment can cause some loss of peripheral (side) vision, but it can preserve and save the rest of the person's vision, especially critical central vision. It might also slightly reduce color vision and night vision.
scleral buckle -  This is a tiny synthetic band that the doctor attaches to the outside of the eyeball. The band gently pushes the wall of the eye in toward the center of the eye. This places the eye wall very close to the detached retina. Natural pumps in the eye then help reattach the retina to the wall.
secondary glaucoma -  These are types of open-angle glaucoma that are caused by medication or other medical conditions.
severe non-proliferative retinopathy - 

In this third stage, many more blood vessels are blocked. This keeps several areas of the retina from receiving the blood supply they need. These areas of the retina send signals to the body to grow new blood vessels for nourishment.
stroma - 

Beneath Bowman's layer is the stroma, which accounts for about 90 percent of the cornea's thickness. It is mostly made of water and collagen. The collagen's unique shape, arrangement, and spacing are important in allowing light to pass through the cornea. The stromal layer is is the part of the cornea that is reshaped in laser vision correction, such as PRK and LASIK procedures.
