The types and severity of high myopic maculopathy in Chinese patients

Abstract

Age and refractive error are important risk factors playing different roles in the development of distinct subtypes and varying severities of high myopic maculopathy. Visual acuity is significantly associated with various subtypes and the severity of high myopic maculopathy.

Extreme Choroidal Thinning in High Myopia

“…12 In eyes with extreme choroidal thinnning, the mean CT was found to be thinnest at the fovea, followed by the nasal and inferior zones, and thickest superiorly and temporally, which is in agreement with other studies. 36 It is important to recognize that extreme choroidal thinning in some eyes with high myopia may differ from typical myopic maculopathy, which is associated with chorioretinal atrophy, lacquer cracks, and decreased visual acuity, 24,37 in terms of the rate of choroidal thinning or visual acuity prognostication. 36 It is important to recognize that extreme choroidal thinning in some eyes with high myopia may differ from typical myopic maculopathy, which is associated with chorioretinal atrophy, lacquer cracks, and decreased visual acuity, 24,37 in terms of the rate of choroidal thinning or visual acuity prognostication.…”

Microincision vitrectomy surgery for myopic foveoschisis

“…The degree of myopic chorioretinal atrophy was determined by fundus photography and categorised as minimal atrophy, lacquer cracks, patchy, diffuse and macular atrophy, as previously described (figure 2). 18 19…”

The noninvasive retro-mode imaging of confocal scanning laser ophthalmoscopy in myopic maculopathy: a prospective observational study

“…With age, eyes with high myopia can potentially develop myopic maculopathy that includes retinochoroidal degeneration in the macula, lacquer crack, hemorrhage, choroidal neovascularization (CNV), or proliferation and atrophy of the retinal pigment epithelium (RPE), all of which are conditions that can lead to poor vision. 1 However, because of the long axis oculi of an eye with myopic maculopathy and the complicated color changes precipitated by various degenerations, it is difficult to clearly identify the lesions via direct or indirect ophthalmoscope. 2 Most secondary lesions of myopic maculopathy can be discovered via fundus fluorescein angiography (FFA), but this procedure is invasive and relatively time consuming.…”
