Factors Influencing Fixation Stability Area: A Comparison of Two Methods of Recording.

Significance: The authors analyze factors influencing bivariate contour ellipse area (BCEA) in healthy and pathologic eyes and how such factors may affect isolated (static BCEA) or microperimetric fixation (dynamic BCEA). They conclude that aging increases both dynamic BCEA and examination time, whereas static BCEA offers less variance and the maximum distinction with pathologic eyes.

Purpose: The aim of this study was to assess factors influencing BCEA and the recording method that offer less variability and thus maximum distinction between healthy and pathologic eyes.

Clinical correlation between retinal sensitivity and foveal thickness in retinitis pigmentosa patients.

Purpose: To investigate the relationship between retinal structure and retinal sensitivity comparing data obtained using spectral-domain optical coherence tomography (SD-OCT) and microperimetry in retinitis pigmentosa (RP) and healthy patients.

Methods: A total of 49 patients (98 eyes) with RP were divided into 4 groups according to the OCT findings: group A, patients with no macular changes; group B, patients with cystoid macular edema (CME); group C, patients with vitreomacular traction (VMT); group D, patients with retinal thinning. As a control group, we enrolled 27 healthy subjects.
