Cluster analysis of computerized visual field and optical coherence tomography-ganglion cell complex defects in high intraocular pressure patients or early stage glaucoma.

CONCLUSION:: In the early stages of glaucoma, the visual field cluster analysis seems to be useful to detect some focal defects that can be otherwise underestimated when globally considering the visual field. In group 3, where the conventional analysis of visual field was normal while the optical coherence tomography-ganglion cell complex exam was abnormal, the visual field cluster analysis showed a topographical correlation with optical coherence tomography-ganglion cell complex defects in more than 70% of the examinations performed. In addition, the patients with abnormal visual field and normal optical coherence tomography-ganglion cell complex were older than those with normal visual field and abnormal optical coherence tomography-ganglion cell complex (66.44 ± 3.51 vs 57.04 ± 5.96 years, p < 0.001 (0.0002)). These results confirm that the reliability of a visual field examination is subjective and decreases with age because of its difficulty and the personal compliance of the patient toward this examination.
