Chapter 11 – High Myopia

The choroid plays an important role in the physiology and pathology of high myopic eyes. The choroid has been demonstrated to be thinner in high myopia comparing to control patients and also has a different profile, having thicker choroid in the temporal side of the macula. There is a positive correlation between visual acuity and choroidal thickness in high myopia. The choroid is of paramount importance in the pathology of the posterior pole in high myopia. Variation of its thickness has been demonstrated in several diseases as lacquer cracks, dome shape macula, different peripapillary anomalies, and posterior staphyloma.
