Focal Choroidal Thickness Hemodynamıcs as a Sign of Macular Neovascularizatıon Activity in Pathologic Myopia

Purpose: To analyze the relationship between a focal increase of choroidal thickness (ChT) and exudative activity of macular neovascularization (MNV) secondary to pathologic myopia.

Methods: Retrospective analysis including eyes with pathologic myopia presenting with a focally increased ChT underneath active MNV. All patients included were treated, and ChT was measured before and after each intravitreal injection by two experienced ophthalmologists.

Results: Fifty-two eyes of 52 patients with myopic MNV (19 men and 33 women) were included in this analysis. ChT at T-1 averaged 51.09 ± 33.56 μ m, whereas at the time of MNV activation (T0), ChT was significantly thicker: 85.11 ± 43.99 μ m ( P < 0.001). After a single intravitreal injection, the ChT significantly decreased to 53.23 ± 34.15 μ m ( P < 0.001).

Conclusion: This study showed that focal ChT variations may be considered an interesting corollary sign of MNV in high myopic patients, indicating the activity of myopic neovascularization.
