Purpose: The aim of the study was to assess the usefulness of visual acuity applications and metamorphopsia applications in the diagnosis and monitoring of neovascular age-related macular degeneration.
Material and Methods: 30 eyes with the active form of neovascular age-related macular degeneration qualified for intravitreal injections of aflibercept were included in the study. Before the first, fourth and seventh injection, the patients underwent ophthalmologic examination including distance visual acuity, near visual acuity, metamorphopsia scores using the M-charts, Amsler test and spectral domain optical coherence tomography. At the same time, an examination of near visual acuity and metamorphopsia was performed using original applications installed on the tablet. The results of the study were subjected to statistical analysis.
Results: During therapy, improvement in distance visual acuity was noted. Regardless the method of examination the fluctuations in distance and near visual acuity and the extent of metamorphopsia were not statistically significant. Significant correlations were found between proprietary mobile applications and commonly used tests. No correlation was found between the degree of metamorphopsia and near visual acuity and the thickness of the retina.
Conclusions: The correlation between the retinal anatomical state in patients with neovascular age-related macular degeneration and function tested with simple tests is poor. The most useful method of monitoring the effects of treatment is distance visual acuity. Mobile applications used during the study correlate with commonly used tests, which in the future gives the possibility of easier and faster examination of patients.
