Perimetric progression using the Visual Field Index and the Advanced Glaucoma Intervention Study score and its clinical correlations.

PURPOSE To evaluate the association between clinical parameters and the diagnosis of progression using VFI (Visual Field Index) and AGIS (Advanced Glaucoma Intervention Study) score in primary open angle glaucoma. METHODS Retrospective study of 517 visual fields of 78 eyes with primary open angle glaucoma analyzed with VFI and AGIS score. Clinical data registered included: age, sphere, pachimetry, basal intraocular pressure (IOP), and IOP during the follow up. RESULTS Only the AGIS score diagnosis of progression was associated with the clinical parameters registered. Among the analyzed data, the mean IOP during follow up (p = 0.0005) and IOP at the third month of follow up (p = 0.004) were statistically associated with progression using the AGIS criteria. CONCLUSION The diagnosis of perimetric progression using the AGIS score in the current study was closer to the real functional progression than the diagnosis using the VFI, as the former was associated with known risk factors for progression in glaucoma.
