Central ECD refers to the number of endothelial cells present per square millimeter in the central cornea. This measurement helps in monitoring the progression of corneal diseases, particularly in conditions where there is a gradual loss of endothelial cells leading to corneal edema and vision loss. Central ECD was assessed using specular microscopy, a non-invasive imaging technique that allows for visualization and quantification of the corneal endothelial cells in the central cornea. A normal ECD in adults typically ranges between 2500 to 3000 cells per square millimeter, although this can vary depending on age and individual variation. A higher value indicates better corneal health and function. A lower value suggests potential endothelial dysfunction or damage. This analysis was performed using data from visits in the COMPASS XXT study. No hypothesis testing was prespecified for this outcome measure. One eye (study eye) contributed data to this analysis.

The CECCV is a measurement used in assessing the variability and quantifying the degree of variation in endothelial cell size within the central cornea. The CECCV measurements were obtained using specular microscopy from endothelial cells within the central region of the cornea. A higher CECCV suggests greater variability in endothelial cell size within the central cornea and may suggest underlying endothelial cell pathology, such as stress, aging, or certain corneal diseases (e.g. Fuch's endothelial dystrophy). A lower CECCV indicates more uniform cell size distribution, which is typically associated with a healthier endothelial function. This analysis was performed using data from visits in the COMPASS XXT study. No hypothesis testing was prespecified for this outcome measure. One eye (study eye) contributed data to this analysis.

The CEH is a measurement used in assessing the regularity of endothelial cell shape within the central cornea. It provides insights into the structural integrity of the corneal endothelium, aiding in the evaluation of corneal health and diagnosis of endothelial cell-related pathologies. The CEH measurement was obtained using specular microscopy, a non-invasive imaging technique that assesses the regularity of endothelial cell shape within the central cornea. A normal cornea is of hexagonal shape. A higher CEH indicates a greater proportion of endothelial cells with a hexagonal shape, which is associated with a more regular and healthier endothelial cell morphology. A lower CEH suggests decreased hexagonality and may indicate abnormalities in endothelial cell structure or function. This analysis was performed using data from visits in the COMPASS XXT study.

The annualized rate of change in central ECD is used to quantify the rate at which the central ECD changes over time. The annualized rate of change in central ECD is determined by dividing the change in ECD by the duration of observation (in years). A positive annualized rate of change indicates an increase in central ECD over time, suggesting a favorable outcome or the effectiveness of interventions aimed at preserving endothelial cell density. A negative annualized rate of change signifies a decrease in central ECD, which may indicate endothelial cell loss due to factors such as aging, disease progression, or the surgical interventions.

Corneal sequelae are occurrences of complications related to ECL in the cornea and may include corneal edema, decreased visual acuity, corneal decompensation, bullous keratopathy, etc. Corneal sequelae were quantified by counting the instances where patients experienced complications attributable to endothelial cell loss. A higher number of corneal sequelae events may indicate rapid disease progression or inadequate management of conditions leading to endothelial cell loss. A lower number of corneal sequelae events may indicate a favorable response to treatment and successful disease treatment or treatment stabilization.

Central ECD was assessed using specular microscopy, a non-invasive imaging technique that allows for visualization and quantification of corneal endothelial cells in the central cornea. A normal ECD in adults typically ranges between 2500 to 3000 cells per square millimeter, although this can vary depending on age and individual variation. A higher value indicates better corneal health and function. A lower value suggests potential endothelial dysfunction or damage. This analysis was performed using data from the COMPASS study. Only data for subjects with rings visible on the CyPass MicroStent device and ECD data is presented. No hypothesis testing was prespecified for this outcome measure. One eye (study eye) contributed data to this analysis.

SSI events are additional surgical procedures performed after the initial placement of the CyPass micro-stent device to adjust its position or address issues related to its placement. SSI were noted through adverse event reporting, clinical evaluation, comprehensive documentation of outcome assessment and data analysis. A higher number of SSI events may indicate challenges or complications related to the initial placement of the CyPass device, technical difficulties during the initial surgery, device-related issues, or patient-specific factors contributing to the need for additional interventions. A lower number of SSI events may suggest that the initial device placement was successful and well-tolerated, with fewer complications or the need for adjustments. This analysis was performed using data from visits in the COMPASS XXT study. No hypothesis testing was prespecified for this outcome measure. One eye (study eye) contributed data to this analysis.

CyPass micro-stent movement and/or malposition refers to issues related to the displacement or improper positioning of the CyPass Micro-Stent in the eye's drainage angle. The investigator qualitatively and subjectively assessed the position of the device by counting the visible number of rings of the device during a gonioscopic exam, which used a specialized lens to visually assess the position and stability of the CyPass device. Movement and/or malposition may suggest a greater risk of complications or inadequate treatment of glaucoma. This analysis was performed using data from visits in the COMPASS XXT study. No hypothesis testing was prespecified for this outcome measure. One eye (study eye) contributed data to this analysis.

A corneal adverse event is an undesirable occurrence related to the cornea, such as inflammation, edema, epithelial defects, or other complications. The number of corneal adverse events caused by the CyPass Micro-Stent was assessed from patient reporting, clinical observation and documentation during patients' follow-up visits. This analysis was performed using data from visits in the COMPASS XXT study. No hypothesis testing was prespecified for this outcome measure. One eye (study eye) contributed data to this analysis.

Visual acuity was measured with correction in place using letter charts. BCVA [synonymous with Best Corrected Distance Visual Acuity (BCDVA)] at each visit was compared to the participant's best achieved BCVA recorded throughout the 10-year period after CyPass implantation. This analysis was performed using data from the COMPASS study, the COMPASS XT study, and the COMPASS XXT study. No hypothesis testing was prespecified for this outcome measure.

Visual field mean deviation is a measure used in visual field testing to assess the overall sensitivity of a patient's vision compared to a standardized norm. The Humphrey automated perimeter with the 24-2 Swedish Interactive Thresholding Algorithm (SITA) standard testing method was used. Deviations were recorded in decibels. Normal deviation values are typically within 0 to -2 decibels (dB). A more negative number indicates decreased sensitivity and worsening of the overall visual field. This analysis was performed using data from the COMPASS study and data from the COMPASS XXT study. No hypothesis was prespecified for this outcome measure. One eye (study eye) contributed data to this analysis.

CCT is a measurement of the thickness of the cornea at its center and is assessed using a procedure called corneal pachymetry. A high CCT (thick cornea) indicates a central cornea thicker than average and may be associated with conditions such as corneal edema, Fuchs' dystrophy, or ocular hypertension. A low CCT (thin cornea) indicates a central cornea thinner than average and may be a risk factor for developing conditions such as glaucoma. A negative change value indicates a decrease in corneal thickness. This analysis was performed using data from the COMPASS study and data from the COMPASS XXT study. No hypothesis was prespecified for this outcome measure. One eye (study eye) contributed data to this analysis.
