Purpose: This observational study was conducted to determine the association between axial length and central macular thickness in high myopic adults.

Method: After a routine eye examination on myopic adults (SE ≤ -6.00D) without any fundus pathology and age matched controls (SE = 0.00D), their axial length was measured with A-scan ultrasonography and their central macular thickness was obtained by OCT measurements (NIDEK RS-3000 ADVANCE) via macular map.

Results: 300 eyes of 150 subjects and 200 eyes of 100 controls were evaluated NIMS University Ophthalmology OPD over a period of one and a half year from January 2020 to June 2021. There was a positive association between values of spherical equivalent and axial length (p-value 0.00001, t- value 35.006051). Also, a positive correlation was noted between values of spherical equivalent and central macular thickness (p-value 0.00001, t-value 22.853918). This increase was specifically noted after axial length values of 24.5 mm (p-value < 0.00001, t- value 5.524218).

Conclusion: Thus, we conclude that with increasing degrees of myopia, there is axial elongation of the eye ball and also increase in the central macular thickness which should be kept in mind while evaluating high myopes for other macular and glaucomatous diseases.
