Abstract

Campimetry is an important test to detect and monitor central and peripheral ocular dysfunctions, which might indicate the existence of serious conditions such as glaucoma, or the occurrence of strokes or brain tumors. Commercially-available campimeters are expensive and lack portability. We present a portable, low-cost, easy-to-manufacture smartphone-based campimeter. We evaluated our prototype in a user- study, which has shown that its results are consistent with the ones obtained with the Humphrey Field Analyzer - HFA II-i campimeter, with a Pearson correlation coefficient above 0.98 for all sampling posi- tions on the visual field. Moreover, its reproducibility is also comparable to the Humprey campimeter. Given its portability and low cost, our mobile campimeter provides a promising alternative for patient screening in schools and community health centers, as well as for visual evaluation of patients with mobility restrictions, for keeping track of the visual field at home, and for use in communities with limited access to medical services.
