Smash Mouth, “All Star”
Dermatologists, similar to everyone else, are subject to the inevitable: aging. More than 80% of the US population develops presbyopia, an age-related reduction in visual acuity, in their lifetime. The most common cause of refractive error in adults, presbyopia can contribute to reduced professional productivity, and individuals with uncorrected presbyopia face an estimated 8-fold increase in difficulty performing demanding near-vision tasks.1
As specialists who rely heavily on visual assessment, dermatologists likely are aware of presbyopia, seeking care as appropriate; however, visual correction is not one size fits all, and identifying effective job-specific adjustments may require considerable trial and error. To this end, if visual correction may be needed by a large majority of dermatologists at some point, why do we not have specialized recommendations to guide the corrective process according to the individual’s defect and type of practice within the specialty? Do we need resources for dermatologists concerning ophthalmologic wellness and key warning signs of visual acuity deficits and other ocular complications?
These matters are difficult to address, made more so by the lack of data examining correctable visual impairment (CVI) in dermatology. The basis for discussion is clear; however, visual skills are highly relevant to the practice of dermatology, and age-related visual changes often are inevitable. This article will provide an overview of CVI in related disciplines and the importance of understanding CVI and corrective options in dermatology.
CVI Across Medical Disciplines
Other predominantly visual medical specialties such as pathology, radiology, and surgery have initiated research evaluating the impact of CVI on their respective practices, although consistent data still are limited. Much of the work surrounding CVI in medicine can be identified in surgery and its subspecialties. A 2020 study by Tuna et al2 found that uncorrected myopia with greater than 1.75 diopter, hyperopia regardless of grade, and presbyopia with greater than 1.25 diopter correlated with reduced surgical performance when using the Da Vinci robotic system. A 2002 report by Wanzel et al3 was among the first of many studies to demonstrate the importance of visuospatial ability in surgical success. In radiology, Krupinski et al4 demonstrated reduced accuracy in detecting pulmonary nodules that correlated with increased myopia and decreased accommodation secondary to visual strain.
Most reports examining CVI across medical disciplines are primarily conversational or observational, with some utilizing surveys to assess the prevalence of CVI and the opinions of physicians in the field. For example, in a survey of 93 pathologists in Turkey, 93.5% (87/93) reported at least 1 type of refractive error. Eyeglasses were the most common form of correction (64.5% [60/93]); of those, 33.3% (31/93) reported using eyeglasses during microscopy.5
The importance of visual ability in other highly visual specialties suggests that parallels can be drawn to similar practices in dermatology. Detection of cutaneous lesions might be affected by changes in vision, similar to detection of pulmonary lesions in radiology. Likewise, dermatologic surgeons might experience a similar reduction in surgical performance due to impaired visual acuity or visuospatial ability.
