PURPOSE OF REVIEW: The aim of the present review was to summarize the evidence implicating the association between myopia and glaucoma, the possible underlying mechanisms for this relation, and the controversies surrounding detection of glaucomatous changes in coexisting myopia.
RECENT FINDINGS: Numerous studies have shown that increasing categories of myopia are associated with a higher risk for optic neuropathy and glaucoma-like visual field defects. Recently, some high-resolution imaging modalities have been developed that aid further detection of the microanatomical changes of the optic nerve head and thus may provide a new insight to explain the association between myopia and glaucoma. Although the highly myopic eye usually shows many structural and functional defects that are difficult to distinguish from those caused by glaucoma, some new methods have been introduced to better differentiate between these changes.
SUMMARY: The interaction of myopia with glaucoma risk remains complex, largely because of the retinal and nerve fiber layer damage that occurs in myopia alone. Whether to treat for glaucoma relies on the suspicion level of the clinician who must consider other risk factors for vision loss. Ultimately, it is the progression of glaucoma-like findings that determines whether a myopic patient has glaucoma.
