Retinal hemorrhages and cotton wool spots as part of radiation retinopathy will resolve without treatment; however, they are clear indications of retinal damage and are cause for ophthalmologic referral. Retinal edema manifests as blurred vision when it affects the macula. It is diagnosed by careful slit lamp biomicroscopy with the aid of fluorescein angiography. Current treatment options include laser photocoagulation and corticosteroids. Neovascularization (both iris and retinal) is a manifestation of chronic retinal ischemia and is also treated with laser photocoagulation. Because diabetes mellitus and hypertension can mimic and/or potentiate radiation retinopathy, strict control of blood sugar and blood pressure should be emphasized.
The treatment of optic disc edema and optic neuropathy is controversial. While the use of systemic corticosteroids and pressure-lowering medications may be effective, observation is also a viable option.
