 This study investigated the effects of a hyaluronic acid hydrogel loaded with hydroxycamptothacin, HCPT, on scar formation after filtration surgery in a rabbit model. The results showed that HCPT significantly inhibited the growth of rabbit scleral fibroblasts and effectively inhibited scar formation after filtering surgery by accelerating the degradation of extracellular matrix deposition.
