Microperimetry, also referred to as fundus perimetry or fundus-driven perimetry, enables simultaneous acquisition of visual sensitivity and eye movement data. We present sensitivity data collected from 60 participants with normal vision using gaze-contingent perimetry. A custom designed spatially dense test grid was used to collect data across the visual field within 13° of fixation. These data are supplemental to a study in which we demonstrated a spatial interpolation method that facilitates comparison of acquired data from any set of spatial locations to normative data and thus screening of individuals with both normal and non-foveal fixation (Denniss and Astle, 2016) [1]...

BACKGROUND: Intrachoroidal cavitation (ICC) in the temporal peripapillary area is a relatively frequent finding in high myopia. However, ICC associated with a full thickness retinal defect rarely observed. We report an unusual case of ICC combined with a full thickness retinal defect in the papillo-macular bundle, in which the spatially corresponding visual field sensitivity was preserved. CASE PRESENTATION: A high myopic and pseudophakic left eye of a 79-year-old Japanese woman was evaluated with swept source optical coherence tomography (SS-OCT) and Humphrey 30-2 visual field testing for moderate glaucoma...

BACKGROUND/PURPOSE: Previous studies have shown that patients with diabetic macular edema (DME) with relatively good visual acuity can have slow reading speed. The aim of this study was to evaluate the structural-functional correlation in a cohort of patients with DME and to assess whether the central four retinal points on microperimetry (MP4) could be used as a potentially faster and more reliable method of assessing retinal function in patients with DME than reading speed. METHODS: The study was performed on patients with clinically significant DME...

PURPOSE: To demonstrate the usefulness of fundus autofluorescence for diagnosing a subclinical case of Best disease. RESULTS: We describe a 27-year-old white woman without central visual symptoms, visual acuity of 20/12 in both eyes, carrying the previously reported p.Tyr227Cys mutation in the BEST1 gene. Although electrooculography, microperimetry (MP-1), and spectral-domain optical coherence tomography did not reveal unequivocal pathology, fundus autofluorescence imaging allowed to clearly detect a phenotypic correlate of Best disease, namely small areas of significantly increased fundus autofluorescence signals...
