Visual screening methods are the pillars of early detection and good management of ocular diseases, thereby reducing the burdens placed on the healthcare system and promoting the best patient outcomes. A thorough discussion of the visual analysis methods used for the early detection of eye diseases follows. Visual acuity testing, pressure measurement of the intraocular, and fundoscopic examination are part of the examination process. Among others, tools like OCT and retinal imaging are also part of this research, as they can be used to increase the accuracy and precision of early disease detection. The review takes inventory of the particular strengths, restrictions, and clinically relevant details that characterize the different screening techniques and then demonstrates the extent to which they work when applied to other patient populations. Moreover, guidelines are given on how improvements can be made in the ocular screening methods that would lead to an increased detection rate of visual problems and reinforce timely treatment.
