How do you decide the threshold and duration of subretinal fluid that can be safely tolerated in exudative AMD when adjusting treat-and-extend intervals?

How do you decide how much subretinal fluid you tolerate in patients with exudative AMD when using a treat-and-extend approach?

• I aim for complete SRF resolution before extending.
• I tolerate minimal SRF if vision is stable.
• I tolerate persistent low-level SRF indefinitely if OCT and vision are otherwise stable
• I individualize based on patient-specific factors
