Benjamin Franklin once wrote, “an ounce of prevention is worth a pound of cure.”1 Although he was referring to fire prevention, this adage also applies to radiation maculopathy.
Over the years, I have relentlessly sought ways to decrease therapeutic radiation to the fovea and optic nerve. For example, in the 1980s, I studied adding intraocular microwave hyperthermia to lowered doses of plaque radiation therapy for the treatment of choroidal melanoma.2
In 1990, I published on the use of radio-opaque vitreous substitutes to act as an internal shield during plaque radiation therapy.3 This strategy is being pursued today with silicone oil.4
However, it was not until the mid-1990s that I discovered a simple, low-risk opportunity to improve plaque radiation therapy.5–7 Compared to iodine-125, the use of lower-energy palladium-103 photons shifted the intraocular dose distribution.8 It increased the dose within the tumor, while decreasing irradiation of most normal ocular structures.9Continue reading…
"Very well treated by Dr. Finger. He explained everything I needed to know about my issue with detail and attention, putting me at ease and giving me confidence to handle this problem for the rest of my life.”
