Methods of Threshold Estimation (Algorithms) and New Techniques in Perimetry: A Review

Recently, there have been several new developments in automated perimetry that have contributed to enhanced diagnosis and management of glaucoma. This paper will briefly review the classical algorithms of automated perimetry and also the latest advances in automated perimetry strategies, like SITA Faster algorithm. It will also explore the new algorithms for different perimeters and all the novel techniques, which has been shown to be a rapid, effective method of detecting glaucomatous visual field loss and have demonstrated the ability to predict the onset and progression of glaucomatous visual field deficits.
