Using the Veterans Affairs Low Vision Visual Functioning Questionnaire (VA LV VFQ-48), the researchers found an improvement in reading ability and overall visual ability among those allocated to treatment compared to the control arm.The authors correctly note that this is the first RCT to examine the effectiveness of low vision services for patients with glaucoma. In fact, there is also no rigorous evidence for the effectiveness of low vision interventions for patients with other causes of peripheral field loss (PFL) such as retinitis pigmentosa, hemianopia, or dense pan- retinal photogoagulation;2 this lack of evidence is concerning since around one-fifth of patients with low vision have been found to have significant PFL.3 Patodia et al1 point out that different patterns of functional impairment are likely to result from central and peripheral vision loss. Although this has been corroborated by prior research, there is still an inadequate qualitative understanding of how PFL affects patients’ day-to-day lives and how this is impacted by demographic and sociological features such as age, gender, culture, and place.View the original paper by Patodia et al.Ehrlich JRMoroi SEDove Medical PressarticleGlaucomaLow VisionRehabilitationPatient-Reported OutcomesMixed MethodsOphthalmologyRE1-994ENClinical Ophthalmology, Vol Volume 11, Pp 1119-1120 (2017)
