Improving visual acuity

"Improving visual acuity" refers to a clinical outcome and a primary therapeutic endpoint in ophthalmology rather than a specific molecular target, receptor, or enzyme. Visual acuity is defined as the capacity of the visual system for spatial resolution, typically measured by the ability to distinguish characters or symbols on a standardized chart at a specific distance (NIH National Eye Institute). This metric is influenced by the optical quality of the eye, the functional integrity of the retina (particularly the fovea), the health of the optic nerve, and the processing capabilities of the visual cortex (StatPearls: Visual Acuity). In drug development, improving visual acuity is the goal of various pharmacological interventions, such as the use of vascular endothelial growth factor (VEGF) inhibitors to treat neovascular age-related macular degeneration or diabetic edema (PubMed: PMC4311109). While many drugs are developed to achieve this result, the term itself represents a physiological effect or clinical benefit rather than a biological entity that a drug can bind to or modulate directly. Therefore, in the context of target identification, this entry is classified as a clinical indication or outcome measure rather than a therapeutic molecular target.
