Correlation between Axial Length and Presence of Age-Related Macular Degeneration.

Introduction/Background: To describe the relationship between axial length (AL) with progression of age-related macular degeneration (AMD). Methods: This retrospective, consecutive, comparative study, collected anonymized data between January 2010 and December 2015. We included patients with AMD who had AL measured as a prelude to cataract surgery. We excluded those with ocular copathology, incomplete data or choroidal neovascularization (CNV) secondary to pathologic myopia, retinal angiomatous proliferation and idiopathic polypoidal choroidal vasculopathy. AMD was diagnosed by clinical examination prior to biometry. Outcome measures were AL and AMD severity and type. Results: Of 99 eyes 49 had dry AMD and 50 had wet AMD. The mean (± standard deviation) AL of 43 eyes with only macular dru sen was 23.19 ± 0.84 mm, versus 23.24 ± 1.05 in 6 eyes with geographic atrophy, 23.43 ± 1.25 in 39 eyes with wet AMD and 23.36 ± 1.36 in 11 eyes with disciform scarring. Of the wet AMD group only 4% (2 of 50 eyes) had an AL ≥26.00 mm. Conclusions: AL was not found to be associated with the severity of AMD. Acknowledgements: None. [ABSTRACT FROM AUTHOR]
