Clinical Tools
Name: Amsler Grids
Price: Free
The poor sensitivity of the Amsler and the rise of the OCT will see the total demise of the technique as a means of screening for macular degeneration. However, as a means of patient-centred monitoring of macular vision, and for purposes of patient understanding, I think the test will survive. I have started using a free app version (from Konan) of the Amsler grid on domiciliary visits and find that it has some obvious benefits. Firstly, the touchscreen makes it easier for a patient to record their visual distortions and blind areas. Secondly, electronic storage is much better than paper and I fail to see any reason for using a paper version any more.
