Summary: PS group showed differences in ACD, lens thickness, and SE compared to NPS group. Reduced choriocapillaris perfusion, SFCT, and retinal layer thickness were observed in the PS group. Multivariate regression analysis indicated that disc tilt ratio and SFCT were significant predictors of PS.

Summary: This study investigated the characteristics of macular structures and microcirculation in eyes with posterior staphyloma (PS) and explored the factors related to PS in high myopia. Thinner retinal and choroid thickness were observed in patients with PS, and they also had significantly lower subfoveal scleral thickness. The density of retinal deep vascular complex and choriocapillaris perfusion area were also significantly lower in the PS group. Factors such as subfoveal scleral thickness, retinal and choroid thickness, and choriocapillaris perfusion area were found to be significantly correlated with PS.

Summary: The purpose of this study was to examine the bilaterality and symmetry of posterior staphyloma in high myopic eyes. The results showed that 92.8% of the eyes had posterior staphyloma, and 85.6% of the patients had it in both eyes. Patients with bilateral posterior staphyloma showed higher myopic severity and incidence of severe pathologic myopia compared to those with unilateral posterior staphyloma.

Summary: This study found that in highly myopic eyes, myopic traction maculopathy and posterior staphyloma are independently associated with myopic macular degeneration.

Summary: This study investigated the differences in accommodation-induced axial elongation between myopic and nonmyopic children. The results showed that myopic children exhibited significantly greater accommodation-induced axial elongation than nonmyopic children. This finding could support a potential mechanism linking near work, axial elongation, and myopia development in children.

Summary: Posterior scleral staphyloma affects the choroidal blood vessels and matrix components, leading to decreased choroidal thickness. The choroidal structure changes in myopic eyes with longer axial length, with choroidal vessels being more impaired than the stroma. A lower choroidal vascularity index may indicate pathological changes in myopia with longer axial length.

Summary: This study retrospectively investigated the axial length changes in myopic children wearing orthokeratology lenses and found that after initial shortening, the axial length rapidly rebounded during the washout period and shortened again when lenses were re-worn. The changes in axial length were significantly correlated with the initial axial length. Therefore, measuring axial length after the washout period can provide a more objective and accurate evaluation of orthokeratology, and the existence and degree of axial shortening can predict long-term myopia development.

Summary: This study aimed to investigate the cutoff of axial length (AL) change in order to accurately differentiate between progressive and non-progressive myopic children. The results showed that myopic children with non-progressive status had significantly less axial elongation than those with progressive status. An annual AL change cutoff of 0.20 mm/year can be used to differentiate between non-progressive and progressive myopia.

Summary: The study found through a double-blinded randomized clinical trial that violet light-transmitting eyeglasses (VL glasses) have a suppressive effect on myopia in children, particularly in those with shorter near-work time and those who had never worn eyeglasses before the trial. The axial elongation suppressive rate in the VL glasses group was 21.4% over two years.

Summary: This study evaluated the relationship between macular sensitivity and retinal perfusion density in eyes with myopic macular degeneration. The results showed that macular sensitivity decreased with increasing severity of MMD and was significantly associated with deep retinal PD.

Summary: This study analyzed the relationship between diopter and choroidal thickness in myopic children and found significant differences in choroidal thickness among myopic children. Choroidal thickness was positively correlated with diopter and negatively correlated with axial length. Therefore, choroidal thickness is considered an important indicator for evaluating the progression of myopia.

Summary: This study tested short-term axial length changes in myopic individuals using special spectacle lenses. The results showed that the use of these lenses significantly shortened the axial length, indicating a potential effect on the signals of axial elongation from the choroid. These spectacles could be further investigated for myopia control purposes.

Summary: The study investigated the association between different types of posterior staphyloma (PS) and refractive error (RE) after cataract surgery in highly myopic patients. The findings suggest that wide macular PS may be associated with more hyperopic RE after surgery.

Summary: This study investigated the correlation between baseline axial length (AL) and axial elongation in myopes undergoing orthokeratology (ortho-k). The results showed a negative association between axial elongation and baseline AL in the ortho-k group. Furthermore, children aged 8-11 years with longer baseline AL demonstrated slower annual axial elongation during the first 2 years of ortho-k treatment.
