THE RELATIONSHIP BETWEEN THE TYPES OF AXIAL ELONGATION AND THE PREVALENCE OF LATTICE DEGENERATION OF THE RETINA

Purpose: 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 c ompared between eyes with posterior staphyloma and those without poste rior staphyloma. Results: At each axial length, lattice degeneration w as more frequent in eyes without posterior staphyloma (the entire eye elongates) than those with posterior staphyloma (only the posterior po le elongates). The difference was statistically significant (p<0.005-0 .05). Conclusion: The prevalence of lattice degeneration is influenced by the types of axial elongation in high myopic eyes.
