Relationship Between Macular Microvasculature and Visual Acuity in Advanced and Severe Glaucoma: Macular Microvasculature and Visual Acuity.

Abstract Purpose To evaluate the correlation between structural parameters and visual acuity (VA) in advanced glaucoma. Design Prospective, cross-sectional study. Methods A total of 238 eyes from 238 patients (82 men, aged 59.9 ± 13.8 years) from a tertiary center were divided into an advanced (mean deviation of 24-2 visual field tests from −12.01 to −20.0 dB) and severe ( Results In the advanced glaucoma group (133 eyes), superficial (Pearson correlation coefficient, γ = −0.46, P Conclusions Macular VD showed better correlation with VA in advanced glaucoma. Deep macular VD, especially nasal grid, may be a promising structural parameter in severe glaucoma.
