I developed a cystoid macular edema in 2010 because the blood vessels in my retina were leaking, a long-term side effect from the radiation I had back in 1986. Some of the doctors at Stanford thought that the cancer had returned or had come out of stagnation, and I ended up visiting Dr. Abramson in New York at Sloan-Kettering, Who is one of the worlds top retinoblastoma research doctors. He explained the leaking blood vessels and the effects of the radiation, and I came back to California to undergo treatment to fix the vessels. The treatments didn't really work and I ended up getting an internal infection that required surgery to fix, and a month after that surgery my retina detached. Changed doctors, and it turned out that some simple laser treatments solve the original edema problem, but the damage was already done with The failed detachment surgery and a year later I had to go in for more surgery since it wasn't getting better. Every surgery I had from then on had a complication, and basically four surgeries later my eye just sort of gave out and threw a blood clot in the main artery that feeds the retina cells. The radiation treatments and time had hardened that artery and made it susceptible to clots, which was something no one considered until it actually happened.
