More sketches for a new project about myopia (nearsightedness) & myodesopsia (eye floaters) continued~
Pneumatic retinopexy & scleral buckling are different procedures used to fix retina detachments & certain retina tears.
Pneumatic retinopexy is usually done in combination with cryopexy, where 1st very small area of the eye is exposed to extremely cold temperature (via special probe), which stimulates the formation of scar tissue, binding the retina back in place & sealing together torn edges. A small air bubble is injected into the eye & holds the retina back against the inner wall of the eye as the eye heals itself. This is a far less invasive procedure than scleral buckling but can only be done for certain tears/detachments since you have to keep your head in a certain position (1-3 wks) to keep the air bubble in place (i.e. primarily tears/detachments on the upper & back surfaces of the eye’s interior). Scleral buckling is definitely more invasive than pneumatic retinopexy, as a piece of silicone is sewn to the exterior surface of the eye, indenting it & forcefully pushing the eye wall against the detached retina. The piece of silicone is threaded beneath the rectus muscles that enable you to turn your eyes inward/outward/up/down & generally permanently left in place.
