Cataract - Diagnosis

1. Slit-lamp biomicroscopy : To detect location and density of opacity within lens.
2. Potential visual acuity with removal of cataract can be estimated with potential acuity meter (PAM) or laser interferometer.
3. B-scan ultrasound can be used to detect retinal detachment or tumors if severe cataract prevents retinal examination.
4. Glare testing and contrast sensitivity testing can quantitatively estimate functional impact of cataract on vision.
