Abstract
Lacquer cracks are observed as yellowish linear lesions in the posterior fundus in 4.2–15.7% of highly myopic eyes. They represent healed and mechanical breaks of the retinal pigment epithelium (RPE), Bruch’s membrane, and choriocapillaris complex. Their progression patterns are: increase in number, elongation, and progression to patchy atrophy.
Simple hemorrhage is macular hemorrhage that occurs in highly myopic eyes and is most likely caused by the mechanical rupture of Bruch’s membrane and choriocapillaris complex without macular neovascularization. Subretinal bleeding is an indicator of a formation of new lacquer cracks.
Myopic stretch lines are observed as pigmented brown lines running alongside the large choroidal vessels, which represent a proliferation of RPE cells on and around the large choroidal vessels.
