A retina doctor will not recommend surgery unless it is medically necessary, or if there is no alternative treatment option, the US Food and Drug Administration (FDA) said on Friday.
“The FDA is not aware of any FDA-approved treatment that provides a cure to retinal disease,” the agency said in a statement.
The agency said it was working on a guidance to the industry to clarify the need for a cure.
“Currently, there is only one FDA-approved treatment for retinal degeneration, but there is a growing body of evidence that other treatments are potentially effective,” it said.
The FDA said it is “working closely with the industry and its stakeholders to develop a unified set of guidance for FDA-regulated health care professionals that will better reflect the best available evidence.”
The US is one of the few countries where a doctor can prescribe a drug for retinopathy, or the damage caused by the damage to the retina caused by damage to blood vessels in the retina, according to the Cochrane Collaboration.
Retinal diseases affect a large segment of the US population.
About 1.4 million people are estimated to have the condition, according the US Centers for Disease Control and Prevention (CDC).
About a third of the country’s 5.2 million people have at least one type of retinal cancer.
In 2016, the CDC reported more than 3,500 cases of retinitis pigmentosa, a form of retinoic acid-induced damage.
