The standard method for recording visual acuity in infants and preverbal children typically involves the use of specialized tools that can accommodate the unique needs and limitations of this age group. Child Sight Measurement (CSM) is designed specifically to assess visual acuity in young children who may not yet be able to communicate effectively or follow instructions typical for traditional methods, such as using Snellen charts.

CSM often utilizes picture cards or symbols that require minimal verbal interaction and can be more engaging for children. This method allows for more accurate assessments since young children cannot always focus on or understand the tasks required in standard testing methods, making it particularly effective for this demographic. Additionally, it can adapt to varying developmental levels, enhancing its reliability and usability.

In contrast, Snellen charts are designed for older children and adults who can read letters and numbers. Visual field testing and pinhole testing are also more suited to older patients or those who have already developed the ability to respond to dictated visual acuity assessments. Therefore, CSM stands out as the method most appropriate for infants and preverbal children, facilitating accurate and effective visual acuity measurement in this population.
