Figure Lengend Snippet: The SCS microinjector and its drug distribution pattern. (A) The SCS microinjector comprises a 30-gauge microneedle with length markings (e.g., 900 μm and 1100 μm), a conjunctiva-compressing hub, barrel grips, capacity markings, and a plunger handle for precise fluid delivery. (B) Schematic of drug distribution following suprachoroidal administration. The microneedle delivers therapeutics into the suprachoroidal space (SCS), with the green-highlighted area indicating circumferential drug distribution within this compartment (between the sclera and choroid).
