Laroche Glaucoma Risk Calculator
Based on results from the Ocular Hypertension Treatment Study (OHTS) and the European Glaucoma Prevention Study (EGPS), we present a method for estimating if you are at higher risk or lower risk for having or developing glaucoma.
The method may be useful to clinicians and patients in deciding the frequency of examinations, tests, and the potential benefit of starting treatment and or having earlier cataract surgery and micro-invasive glaucoma surgery.

Calculator to Identify Glaucoma Patients and Stratify Management by D. Laroche, K.Rickford, E.V. Mike, L. Hunter, E. Ede, C. Ng, and J.Douglas (doi: 10.1155/2022/5288726. PMID: 35957745; PMCID: PMC9357680)
Directions for use This calculator requires only three factors to estimate glaucoma risk:
- Age
- Intraocular pressure (IOP)
- Central corneal thickness (CCT)
Methods
- For this Point System, you will select the age, intraocular pressure and central corneal thickness boxes for each eye.
- The results will appear in the two blue boxes beneath the table
Limitations and cautions
- The prediction methods presented here are derived from the Laroche Glaucoma calculator study. There is no guarantee that the predicted risk is accurate for individual patients.
- The predictions are more likely to be accurate for patients who are similar to the participants studied in the study. This calculator should exclude congenital and juvenile glaucoma in younger patients.
- These prediction models were derived from studies of patients with and without glaucoma. It is not clear whether these models also predict the progression of established disease or the development of visual disability from the need for glasses, retinopathy, cataracts, and other diseases.
- This calculator does not require optic nerve evaluation, vertical cup-to-disc ratio, nor visual field evaluation. These evaluations should be performed as soon as possible on high-risk patients as part of a complete ophthalmic examination. On low-risk patients, a complete ophthalmic examination should be performed within 6-12 months.
- The risks derived using these methods are designed to aid but not to replace clinical judgment and a complete ophthalmic examination.
