Screening

Screening

Cataracts are identified through routine comprehensive ophthalmologic examination rather than population-based laboratory testing or imaging studies. Slit-lamp examination following pupillary dilation remains the primary method for detecting and classifying lens opacities.[1]

Screening for cataracts is typically incorporated into periodic eye examinations, particularly in older adults and individuals with known risk factors such as diabetes mellitus, corticosteroid use, or significant ultraviolet exposure.[1]

Early identification of cataracts allows monitoring of disease progression and timely referral for surgical evaluation when visual impairment becomes functionally significant.[1]
