Segmentation by type classifies therapies into anti‑VEGF agents, corticosteroids, gene therapies, ocular implants, and combination regimens, each with distinct mechanistic sub‑categories. Anti‑VEGF agents dominate with sub‑types like bevacizumab, ranibizumab, aflibercept, and faricimab, collectively delivering the bulk of clinical outcomes across AMD and DR. Corticosteroid treatments split into intravitreal injections (triamcinolone) and sustained‑release implants (dexamethasone, fluocinolone), offering alternative pathways for patients refractory to anti‑VEGF therapy. Gene‑therapy products, exemplified by voretigene neparvovec, target hereditary retinal diseases, introducing a curative paradigm albeit with limited current uptake. Ocular implants, including refillable port‑delivery systems, extend drug residence time and reduce treatment burden. Finally, combination regimens—pairing anti‑VEGF with corticosteroids or anti‑inflammatory agents—aim to synergize efficacy and address heterogeneous disease phenotypes. This taxonomy clarifies how each type contributes to overall market size through differentiated clinical value and pricing structures.
