Early detection of glaucoma with the STAR ll Calculator

According to the Ocular Hypertension Treatment Study1 (OHTS), the cumulative risk of developing primary open-angle glaucoma (POAG) for those with ocular hypertension (OHT) was 4.4 per cent in treated eyes and 9 per cent in controls. This represents a 50 per cent reduction of risk. Therefore early identification of patients at risk of developing POAG is critical.

Risk factors

The OHTS identified five key risk factors in predicting the likelihood of progression from OHT to POAG;

The STAR (Scoring Tool for Assessing Risk) calculator is based on a model derived from a collective assessment of key risk factors (Figure 1). This tool enables a practitioner to estimate the degree of risk for any individual patient of progressing from ocular hypertension to glaucoma within five years.
