Intraocular pressure (IOP) is a diagnostic measurement of the fluid pressure, measured in millimeters of mercury, inside the eye. IOP was measured using Goldmann applanation tonometry or by use of a Tonopen tonometer. Normal eye pressure is usually considered to be between 10 and 20 mmHg (AAO.org). Untreated elevated eye pressure is a risk factor for glaucoma.

Population: Defined as all enrolled participants who were administered CLS-AX, and from whom at least one post-Baseline safety measurement was obtained.

Number of participants receiving additional intravitreal aflibercept injections during the course of the study for nAMD. Participants qualified to receive additional IVT aflibercept injections based on protocol-defined criteria, including 1) loss of 10 or more letters in BCVA compared to the best prior study-assessed BCVA in the study eye that was attributed to intra- or sub-retinal fluid, 2) increase in central subfield thickness \>75 microns from Baseline in the study eye, or 3) presence of vision-threatening hemorrhage due to AMD in the study eye. Additionally, a participant could receive additional IVT aflibercept injections in the study eye for reasons beyond the protocol-defined criteria if it was in the participant's best interest per the Investigator's judgment following best medical practice.

Central subfield thickness (CST) is a diagnostic measurement used in identifying the presence of edema in the circular area 1 mm in diameter centered around the fovea. CST was measured using spectral domain optical coherence tomography (SD-OCT). A central reading center graded the SD-OCT digital images. A negative change from baseline value represents a reduction in macular edema. Only images that were gradable by the central reading center were included in the analysis.
