Precision tools for retinal practice. Each calculator lives on its own page — self-contained, mobile-ready, and clinically verified.
Step-by-step dilution protocol for IVT medications — vancomycin, ceftazidime, amikacin, amphotericin B, dexamethasone, foscarnet, ganciclovir, and more.
Structured OCT-based assessment of neovascular AMD disease activity — scores IRF, SRF, PED, haemorrhage, BCVA and CMT change to guide treat-and-extend decisions.
5-year risk estimates for PDR progression, clinically significant DME, and moderate vision loss — based on UKPDS, WESDR, and ETDRS-derived risk factors with evidence-based recommendations.
Anti-VEGF injection interval calculator — PRN, T&E, and fixed dosing schedules for AMD and DME.
Instant conversion between Snellen, LogMAR, decimal, ETDRS letters, and percentage vision.
Determine if a change in CMT is clinically significant vs within test-retest variability for your OCT device.
Estimate 5-year risk of PDR and DME based on ETDRS grade, HbA1c, duration, and BP control.
Structured scoring of nAMD activity based on OCT features — fluid type, location, and change from baseline.
