A clinical comparison of two methods of glare testing

Ophthalmic Surg. 1987 Sep;18(9):680-2.


We evaluated two methods of glare testing, the Miller-Nadler Glare Tester (M-NGT, Titmus Optical, Inc.) and the Brightness Acuity Tester (BAT, Mentor O & O, Inc.). Resulting Snellen visual acuities both for a control group of normal volunteers and for a study group with cataract or posterior capsule opacification were compared using the two glare testers. The decreases in Snellen visual acuities were comparable in the eyes with cataract. No glare disability was measured in the control group. There was greater glare disability using the BAT compared with the Miller-Nadler test when eyes with posterior capsule opacities were compared.
