Fibroblast-loaded carboxymethyl chitosan-aldehyde hyaluronic acid injectable hydrogel for scleral remodelling to prevent development of myopia.

ABSTRACT: High myopia severely threatens the visual health of adolescents, with pathological features of decreased collagen aggregation and scleral thinning, ultimately leading to axial elongation on preretinal imaging. Fibroblasts play crucial roles in scleral remodelling and myopia prevention. In this work, we developed a fibroblast-loaded carboxymethyl chitosan-aldehyde hyaluronic acid (CMCS-HA-CHO) injectable hydrogel for anti-scleral remodelling. The CMCS-HA-CHO hydrogel is formed through simple mixing under mild conditions via a Schiff base reaction between CMCS and HA-CHO. The CMCS-HA-CHO hydrogel can be injected into a posterior sclera with a low modulus, and the increasing modulus over time provides good mechanical support to the sclera. The hydrogel demonstrated excellent cytocompatibility
