Abstract

Background: To find a correlation of the disc damage likelihood scale (DDLS) scale with visual field indices and its diagnostic power in cases of glaucoma.
Materials and Methods: The study enrolled 198 patients suffering from primary open angle glaucoma. The patients were investigated using Humphreys perimetry and ocular coherence tomography (OCT). The DDLS scoring for each patient was done which was then correlated with visual field indices and the accuracy of DDLS in scoring different stages of glaucoma was studied.
Design of Study: Single center, prospective, observational study.
Results: The DDLS showed a strong correlation with cup-disc ratio, a good correlation with visual field index and mean deviation values and a weak correlation with foveal sensitivity. Also, the scale showed 68.9%, 82.6% and 100% diagnostic accuracy in cases of mild, moderate and severe glaucoma respectively.
Conclusion: The DDLS is a strong adjunctive diagnostic tool that has helped in the diagnosis of glaucoma.
