The relationship between the types of axial elongation and the prevalence of lattice degeneration of the retina.
OBJECTIVE
To assess the relationship between the prevalence of lattice degeneration and the types of axial elongation.


METHODS
Nine hundred seventy eyes of 542 highly myopic patients with axial length of 26.00-31.99 mm were evaluated by using A-scan axial length measurements and fundus examinations. Then the prevalence of lattice degeneration was compared between eyes with posterior staphyloma and those without posterior staphyloma.


RESULTS
At each axial length, lattice degeneration was more frequent in eyes without posterior staphyloma (the entire eye elongates) than those with posterior staphyloma (only the posterior pole elongates). The difference was statistically significant (p<0.005-0.05).


CONCLUSIONS
The prevalence of lattice degeneration is influenced by the types of axial elongation in high myopic eyes.
