Organization, Consolidation and Presentation of Financial Statements [Abstract]
Operations	1. Operations EyePoint Pharmaceuticals, Inc., a Delaware corporation (together with its subsidiaries, the Company), is a clinical-stage biopharmaceutical company committed to developing and commercializing innovative therapeutics to help improve the lives of patients with serious retinal diseases. The Company's pipeline leverages its proprietary bioerodible Durasert E™ technology (Durasert E™) for sustained intraocular drug delivery. The Company’s lead product candidate, DURAVYU™, previously EYP-1901, is an investigational sustained delivery treatment for anti-vascular endothelial growth factor (anti-VEGF) mediated retinal diseases combining vorolanib, a selective and patent-protected tyrosine kinase inhibitor with Durasert E™. DURAVYU™ is currently in Phase 3 global, pivotal clinical trials for wet age-related macular degeneration (wet AMD), the leading cause of vision loss among people 50 years of age and older in the United States and in Phase 2 clinical trials for diabetic macular edema (DME). Additional pipeline programs include EYP-2301, a promising TIE-2 agonist, razuprotafib, f/k/a AKB-9778, formulated in Durasert E™ to potentially improve outcomes in serious retinal diseases. The Company plans to identify and advance additional product candidates through clinical and regulatory development for its pipeline. This may be accomplished through internal discovery efforts, research collaborations and/or in-licensing arrangements and potential acquisitions of additional products, product candidates or technologies. Liquidity The Company had cash, cash equivalents and investments in marketable securities of $370.9 million at December 31, 2024. The Company has a history of operating losses and has not had significant recurring cash inflows from revenue. The Company’s operations have been financed primarily from sales of its equity securities, issuance of debt, and a combination of license fees, milestone payments, royalty income and other fees received from its collaboration partners. The Company anticipates that it will continue to incur losses as it continues the research and development of its product candidates, and the Company does not expect revenues from its product sales to generate sufficient funding to sustain its operations in the near-term. The Company expects to continue fulfilling its funding needs through cash inflows from revenues, licensing and research collaboration transactions, additional equity capital raises and other arrangements. The Company believes that its cash, cash equivalents and investments in marketable securities of $370.9 million at December 31, 2024, will enable the Company to fund its current and planned operations for at least the next twelve months from the date these consolidated financial statements were issued. Actual cash requirements could differ from management’s projections due to many factors, the timing and results of the Company’s clinical trials for DURAVYU™, additional investments in research and development programs, competing technological and market developments, and the costs of any strategic acquisitions, and/or development of complementary business opportunities.
