Exclusion criteria were any history of prior vitreous or retinal surgery or evidence of retinal diseases (other than myopic degeneration
, such as age-related macular degeneration, macular hole, and foveal hypoplasia) affecting the retinal or choroidal vasculature by history or examination, presence of media opacities preventing reliable retinal thickness which prevents good visualization of the retinal structure, having systemic diseases such as glaucoma or diabetes mellitus which might affect the ocular circulation, and medication usage within 2 weeks of measurements.
The exclusion criteria were any ocular disorders except ametropia, any systemic diseases, a history of intraocular surgery or ocular trauma, a history of posterior segment laser treatment, a history of ocular hypertension or glaucoma, signs of myopic degeneration or a pathologic form of myopia, an inability to tolerate OCTA, and poor-quality images.
Of note, we found that both superficial and deep macular vascular densities were not significantly different among the three myopia groups and we demonstrated that SE did not influence the macular vascular density in myopic eyes without myopic degeneration or pathologic changes.

She had been referred to the HES one year ago for 'retinal thinning', which was diagnosed as being peripheral myopic degeneration
; no treatment had been performed and the patient was discharged.
Other causes of visual impairment (binocular VA of less than 6/18) and sight loss identified were AMD (52.9%), cataract (35.9%), glaucoma (11.6%), myopic degeneration
(4.2%) and diabetic eye disease (3.4%).
: The elongation of the globe in this condition can lead to islands of chorioretinal degeneration, progressing to retinal pigment epithelium atrophy
Peripheral retinal myopic degenerations
were observed in 26 of the 27 eyes included in the study, while macular degeneration markedly affecting visual outcomes was seen in three eyes (Table-1).
