laser photocoagulation subthreshold laser therapy 2021-02-11T13:52:41Z PMID:31402999 Subthreshold therapy is photocoagulation that does not produce clinical or histologic evidence of retinal damage. Therapeutic benefit is thought to be derived by inducing thermal stress on RPE cells. The goal of the subthreshold therapy is to maintain the temperature rise below the threshold of irreversible thermal damage. The main types are micropulse, selective retinal therapy (SRT), and continuous wave laser with EndPoint Management (algorithm/protocol). XCO:0000803 experimental_condition_ontology slaulede
