Visual acuity was evaluated using teller acuity cards (TACs). MRI of the brain and orbit was performed using three-dimensional high-resolution, volumetric heavily T2-weighted sequences to screen for brain pathologies and measure optic nerve dimensions at two locations. The correlation between visual acuity and optic nerve dimensions was analyzed. The Chi-square test was employed to assess significance using SPSS software.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>RESULTS:<\/jats:title>\n                    <jats:p>\n                      In our study, 64% (\n                      <jats:italic toggle=\"yes\">n<\/jats:italic>\n                      = 38) of the participants were children under 3 years of age. The severity and characteristics of CVI influenced visual functioning at different ages. As children with CVI grew older and moved from Phase I to Phase III, the proportion with very low visual acuity significantly decreased from 85.2% in Phase I to 22.2% in Phase III and from 63.2% in the &lt;3-year age group to 18.2% in more than 5-year age group. No direct correlation was found between optic nerve dimensions and visual acuity but optic disc changes such as optic disc pallor significantly correlated with low visual acuity.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>CONCLUSION:<\/jats:title>\n                    <jats:p>Our findings suggest that there may not be a direct correlation between optic nerve dimensions and visual acuity in children with CVI. However, optic disc changes do correlate with visual acuity, but optic disc changes alone are not a criterion for assessing visual function. Additionally, our study highlights the significance of a combined assessment by a neuro- ophthalmologist and neuro-pedaitrician in children with CVI.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.4103\/ojo.ojo_238_23","type":"journal-article","created":{"date-parts":[[2024,10,30]],"date-time":"2024-10-30T13:18:25Z","timestamp":1730294305000},"page":"371-375","update-policy":"https:\/\/doi.org\/10.1097\/lww.0000000000001000","source":"Crossref","is-referenced-by-count":1,"title":["Correlation of optic nerve on magnetic resonance imaging with visual acuity in children with cerebral visual impairment"],"prefix":"10.4103","volume":"17","author":[{"given":"Veenish","family":"Samvedya","sequence":"first","affiliation":[{"name":"Department of Ophthalmology, Jawaharlal Nehru Medical College, KLE Academy of Higher Education and Research, Belagavi, Karnataka, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"K.
