Abstract
Purpose :
To evaluate whether there is a relationship between cognition and the visual field variability observed in glaucoma patients.
Methods :
Methods: In this cross-sectional study, one hundred and eight patients, all over 18 years old and diagnosed with glaucomatous neuropathy without any other ocular diagnosis were inclued. Each patient had a campimetry visual field SITA Standard 24-2, and after the exam, the patient answered the following questionnaires: Mini-Mental State Examination (MMSE) and Montreal Cognitive Assessment (MoCA), both being questionnaires for cognition assessment questionnaires. Only reliable visual field were considered for the final analysis (fixation loss < 33%, false positive and false negative < 20%). Once the questionnaires were answered, a computerized analysis (STATA 13.0 software) of the results was then performed.
Results :
The mean age of the patients was 61.47 ± 16.77 years. The mean of the MoCA values was 17.80 ± 5.61 points (reference normal value > 22 points). The mean of the MMSE values was 25.01 ± 3.86 points (reference normal value > 24 points). The worsening of cognitive level was significantly associated with patients who had peripheral visual field defects (p = 0.041) in reliable visual fields. Also worse cognitive level assessed with both questionnaires were directly associated with worsening of the MD of visual field even with acceptable reliable visual fields.
Conclusions :
The results showed that there is a correlation between the cognitive impairment of the patient and the pattern of visual field loss with reliable visual fields. Also indicated that cognitive worsening was linearly proportional to the worsening of the visual field defect in reliable visual fields.
