Title: $Comments on: Refractive changes during off-the-axis retinoscopy in myopia
Abstract: Dear Editor, For an intriguing perspective on how off-axis retinoscopy generated the refractive error, I read the original study "Refractive changes during off-axis retinoscopy in myopia."[1] I would like to congratulate the authors on the success of their original article. In the original article, it was speculated that a higher degree of eccentricity resulted in a higher number of retinoscopy errors. Earlier, authors proved myopia and oblique astigmatic error were attributed when light rays impacted the lens obliquely likewise.[2] Sng et al.[3] also showed relative peripheral hyperopia in myopic individuals and relative peripheral myopia in emmetropic individuals. I think that eccentricity measurement while performing off-axis retinoscopy should be included in this study. In the column of seidel aberration of the human eye, there are five different types of aberrations (spherical aberration, COMA, astigmatism, curvature of field, and distortion) that play a major role in an induced refractive error in the human eye.[4] If the study participants chosen were from an emmetropic population, a statistically significant difference could have been discovered. It will be simpler for everyone to grasp if the author can additionally concentrate on a specific sort of aberration that is causing refractive error while doing off-axis retinoscopy because the human eye's entire refractive system is curved. This will make it easier for everyone to understand and access information. Financial support and sponsorship Nil. Conflicts of interest There are no conflicts of interest.
