Readiness of the tabletop screen-based perimetry tests for screening and monitoring glaucoma

The necessity of glaucoma screening for the general population and the need to frequently monitor established glaucoma finds a promising solution in readily available perimetry devices. Some of the common readily available perimetry devices include smartphone-based perimetry inserted into virtual reality headsets, personal computer-based (laptop-based and desktop-based) perimetry, and tablet-based perimetry. Virtual reality headsets, though increasingly affordable, are not commonly found in typical clinical setups or home environments, limiting their feasibility for home-based monitoring or widespread clinical deployment. Using a smartphone as a standalone device, placed on a tabletop, is constrained by limited screen size and field of view, rendering it unsuitable for comprehensive visual field testing. Personal computer-based and tablet-based perimetry leverages commonly available devices, offering a practical and scalable alternative. Personal computer-based and tablet-based perimetry, collectively referred to as tabletop screen-based perimetry in this review, are not intended to replace clinical static automated perimetry (SAP) but rather to complement it, addressing the demand for frequent assessments in glaucoma care and enabling high-volume screening in population settings. This review summarises the readiness of tabletop screen-based perimetry tests, highlighting their accessibility, stimulus and testing parameters. The review will help clinicians in selecting appropriate perimetry techniques for home monitoring or screening glaucoma and support researchers in designing future studies.
