How might Coats disease be treated?

The treatment of Coats disease depends on the signs and symptoms present in each individual and the stage at which the individual is diagnosed.[1] Treatment is usually directed towards closing the vessels that are leaking and salvaging as much vision as possible.[2] A procedure that uses extreme cold to destroy the blood vessels (cryotherapy), and/or a procedure that uses intense, focused light (laser therapy) to heat and destroy tissue may be used alone or in combination to treat the telangiectasia associated with the disease.[1] These procedures are commonly used during the early stages of the disease.[2] More advanced cases may require surgical treatment.[2]. Surgery to reattach the retina may be necessary for retinal detachment.[1] Drainage of fluid or surgically removing the substances that fill the eyeball between the lens and the retina (vitrectomy) may also be used to treat Coats disease when a retinal detachment is present. A procedure in which the vessels involved are heated and destroyed (diathermy) has also been used to treat the disease.[1]
