Description: Glaucoma is a chronic and progressive entity of vision loss that requires detailed monitoring of visual function. In 2013, it was reported that the worldwide prevalence of glaucoma is estimated to be 64.3 million and is expected to increase to 111.8 million in 2040 (Tham YC et al., 2014). In the context of glaucoma diagnosis and management, standard automated perimetry (SAP) is the most utilised investigative technique used by eye health clinicians, with the 24-2 or the 30-2 being the mainstay (Hejil A, et al., 2003). This rationale was adopted under the premise that Glaucoma is a disease affecting the peripheral and mid-peripheral vision in early disease, with changes to central vision only occurring in advanced stages of the disease. Although, with the advent of spectral-domain optical coherence tomography (SD-OCT), there is emerging evidence to suggest the macula ganglion cell complex is affected in early disease processes (Hood DC et al., 2011; Hood DC et al., 2013). Hence, there is conjecture as to whether introducing the 10-2 SAP testing algorithm to Glaucoma screening may provide an added benefit in detecting perimetric changes in early Glaucoma (Kim EK et al., 2021). Therefore, in this scoping review our aim is to analyse the literature comparing the 24-2 and 10-2 SAP in the diagnosis of early glaucoma, whilst also assessing the practicability of additional perimetry testing in clinical practice.
