Rigorous evidence that screening for primary open-angle glaucoma in asymptomatic adults reduces the risk of blindness or improves quality of life does not exist. So it is not surprising that the latest assessment of this practice by the US Preventive Services Task Force (USPSTF) concludes that current evidence is insufficient to evaluate the balance of benefits and harms of such screening. But ophthalmologists, while acknowledging the limited evidence, say screening is still beneficial.
