“…Results of the correlation between spatial contrast sensitivity and reading speed are in accordance with earlier research. 11,15,29,30 To our knowledge the association between temporal contrast sensitivity and reading speed has not earlier been described for participants with macular pathologies. In the present study, moderate (r=0.352; p=0.015) to strong (r=0.661; p<0.001) correlations were found between spatial contrast sensitivity and temporal contrast sensitivity, respectively, and reading speed.…”

For spatial CS and temporal CS, moderate to strong correlations were found, respectively, with reading speed in patients with maculopathies. The stronger association between temporal CS and reading speed is suggested to reflect a high sensitivity for neural integrity of temporal CS. The differences in coefficients of repeatability and reproducibility could be explained by the psychometrical differences between methods.

Visual field deficits are common in neurologic disease conditions such as cerebrovascular disease, traumatic brain injury, and brain tumors. Loss of visual fields may lead to impairment of reading skills (hemianopic dyslexia) and limitations of daily activities such as driving, which can have a significant impact on an individual's socioeconomic status and quality of life. Moreover, patients with motor deficits from neurologic diseases have a 20% decreased likelihood of achieving independence in ambulation and self-care activities with coexisting hemianopia. Studies on the natural history of homonymous hemianopia have shown that spontaneous improvement of visual fields may occur in less than 40% of individuals early in the disease process. Improvement is usually incomplete, which implies that a significant number of individuals will be left with a disabling visual deficit. Although several methods of rehabilitation (optical, compensatory, and restitution therapy) are used in practice, none, unfortunately, have shown consistent and significant benefits. In this review, the authors focus on the natural history, impact, prognosis, and treatment modalities for neurologic field defects.

Microperimetry is a novel technique for assessing visual function that appears particularly suitable for age-related macular degeneration (AMD). Compared with standard automated perimetry, microperimetry offers several unique features. It simultaneously images the fundus, incorporates an eye-tracking system to correct the stimulus location for fixation loss, and identifies any preferred retinal loci. We identified 52 articles that met the inclusion criteria for a systematic review of microperimetry in the assessment of visual function in AMD. We discuss microperimetry and AMD in relation to disease severity, structural imaging outcomes, other measures of visual function, and evaluation of the efficacy of surgical and/or medical therapies in clinical trials. The evidence for the use of microperimetry in the functional assessment of AMD is encouraging. Disruptions of the ellipsoid zone band and retinal pigment epithelium are clearly associated with reduced differential light sensitivity despite the maintenance of good visual acuity. Reduced differential light sensitivity is also associated with outer segment thinning and retinal pigment epithelium thickening in early AMD and with both a thickening and a thinning of the whole retina in choroidal neovascularization. Microperimetry, however, lacks the robust diffuse and focal loss age-corrected probability analyses associated with standard automated perimetry, and the technique is currently limited by this omission.
