How this service works
OHTS-EGPS 2007 Table 6: 5-year primary open-angle glaucoma risk in untreated ocular hypertension from age, mean IOP (mm Hg), mean central corneal thickness (microns), mean vertical cup-disc ratio, and mean Humphrey pattern standard deviation (dB). Point bands map to 4%, 10%, 15%, 20%, or 33%. No race (dropped in the multivariate model). No diabetes term. Not a glaucoma diagnosis or drop order. magent does not measure IOP or pachymetry.
Output
Returns a point total derived from the five OHTS-EGPS Table 6 inputs and maps it to one of five 5-year POAG risk bands: 4%, 10%, 15%, 20%, or 33%. Does not produce a diagnosis, prescribe treatment, or measure any clinical values itself.
Example use cases
Pre-treatment glaucoma risk counseling
“My patient has ocular hypertension and we're deciding whether to start drops. They're 63 years old, mean IOP 27 mm Hg, CCT 538 microns, vertical cup-disc ratio 0.55, and Humphrey PSD 2.6 dB. Can you run the OHTS-EGPS Table 6 calculation and tell me their 5-year risk band?”
Monitoring borderline ocular hypertension
“I have a 47-year-old with borderline ocular hypertension — mean IOP 22.5, CCT 590 microns, cup-disc ratio 0.35, and PSD 1.7 dB. Use the OHTS-EGPS 2007 model to give me their 5-year POAG risk so I can decide on observation vs treatment.”
High-risk glaucoma suspect documentation
“Document the OHTS-EGPS glaucoma risk score for a 72-year-old patient: IOP 29 mm Hg, CCT 510 microns, cup-disc ratio 0.65, PSD 3.1 dB. I need the point total and the 5-year risk percentage band for the chart.”
Technical details
Endpoint
GEThttps://api.magentlab.com/api/calc/ohtsWhen to prefer
Use this endpoint when you need a validated, published clinical risk score specifically from the OHTS-EGPS 2007 Table 6 model for untreated ocular hypertension patients. Prefer this over general risk tools when the clinical question is 5-year POAG conversion probability without race as a covariate and without a diabetes term, matching the original multivariate model. Not appropriate for patients already on IOP-lowering treatment, for diagnosing glaucoma, or for measuring clinical parameters — inputs must come from clinical records.
Side effects
- Age outside 30–80 range returns validation error
- IOP outside 20–32 mm Hg range rejected
- CCT outside 475–650 microns range rejected
- PSD outside 0.5–8 dB range rejected
- Cup-disc ratio outside 0–1 rejected
- Missing any required query parameter returns 400-level error
- Payment not included or insufficient USDC balance blocks call
