Purpose: This study was designed to determine whether the anterior scleral thickness is affected by axial elongation and to investigate the association between anterior scleral thickness and various ocular parameters in myopic eyes. Methods: This cross-sectional study included 79 healthy myopic participants. Anterior scleral thickness was measured in eight meridians (superior-nasal [SN], superior [S], superior-temporal [ST], temporal [T], inferior-temporal [IT], inferior [I], inferior-nasal [IN], and nasal [N]) using anterior segment optical coherence tomography. Bruch’s membrane opening (BMO) area, width of β-parapapillary atrophy with and without Bruch’s membrane (PPA+BM and PPA-BM), and the global peripapillary and subfoveal choroidal thickness (CT) were additionally measured. Age- and sex-adjusted partial correlation analysis and linear regression analysis were performed to examine the effects of axial length and various ocular parameters on anterior scleral thickness in myopic eyes. Results: The mean age of the included participants was 27.03 ± 2.70 years. Overall, the anterior scleral thickness varied topographically according to the meridians and distance from the scleral spur. In the partial correlation analysis controlled for the effect of age and sex, increasing axial length was related to anterior scleral thinning at several measurement points along the T, I, and N meridians. Among the several ocular parameters, multivariate linear regression analysis with age, sex, and axial length as covariates revealed that central corneal thickness, intraocular pressure, and BMO area were significantly associated with anterior scleral thickness. Conclusion: In conclusion, there was a close relationship between the anterior scleral thickness and several ocular parameters in myopic eyes. These features should be taken into consideration when managing myopia, and our results might have important implications for understanding the pathogenesis of scleral changes during axial elongation.

Background: In surgical correction of adult spinal deformity (ASD), pelvic incidence (PI)-lumbar lordosis (LL) plays a key role to restore normal sagittal alignment. Recently, it has been found that postoperative lordosis morphology act as an important factor in preventing mechanical complications. However, there have been no studies on the effect of postoperative lordosis morphology on the restoration of sagittal alignment. The primary objective of this study was to evaluate the effect of postoperative lordosis morphology on achievement of optimal sagittal alignment. The secondary objective was to find out which radiographic or morphologic parameter affects sagittal alignment in surgical correction of ASD. Methods: 228 consecutive patients with lumbar degenerative kyphosis who underwent deformity correction and long-segment fixation from T10 to S1 with sacropelvic fixation and follow-up over 2 years were enrolled. Patients were divided according to whether optimal alignment was achieved (balanced group) or not (non-balanced group) at last follow-up. We analyzed the differences of postoperative radiographic parameters and morphologic parameters between two groups. Correlation analysis and stepwise multiple linear regression analysis was performed to predict the effect of PI-LL and morphologic parameters on the sagittal vertical axis (SVA). Results: Of 228 patients, 195 (85.5%) achieved optimal alignment at last follow-up. Two groups significantly differed in postoperative and last follow-up LL (p < 0.001 and p = 0.028, respectively) and postoperative and last follow-up PI-LL (p < 0.001 and p = 0.001, respectively). Morphologic parameters did not significantly differ between the two groups except lower lordosis arc angle (=postoperative sacral slope). In correlation analysis and stepwise multiple linear regression analysis, postoperative PI-LL was the only parameter which had significant association with last follow-up SVA (R2 = 0.134, p < 0.001). Morphologic parameters did not have any association with last follow-up SVA. Conclusions: When planning spine reconstruction surgery, although considering postoperative lordosis morphology is necessary, it is still very important considering proportional lordosis correction based on individual spinopelvic alignment (PI-LL) to achieve optimal sagittal alignment.

Purpose: To evaluate the visual outcome after cataract operations in high myopia patients, whose axial length differences are longer than 2 mm.Methods: A retrospective study was conducted on patients who had received phacoemulsification cataract surgery from January 2014 to June 2020. The patients whose axial lengths and inter-eye axial lengths exceeded 26 and 2 mm, respectively, were selected. Demographic data, axial lengths, central subfield macular thickness, retinal nerve fiber layer, and best-corrected visual acuities (BCVAs) before and at 6 months postoperatively were collected. The factors related to visual outcome were analyzed using univariate, multivariate linear regression.Results: Twelve patients had an inter-eye axial length difference longer than 2 mm. The average axial lengths of longer and shorter eyes were 29.17 ± 1.94 and 26.66 ± 2.51 mm, respectively (p = 0.02, Mann-Whitney U-test). The BCVAs (logarithm of minimal angle of resolution, logMAR) of the longer and shorter eyes before the surgery were 1.09 ± 0.62 and 0.19 ± 0.16, respectively (p = 0.03, Mann-Whitney U-test). The BCVAs (logMAR) of the longer and shorter eyes 6 months after surgery were 0.19 ± 0.16 and 0.08 ± 0.10, respectively (p = 0.11, Mann-Whitney U-test). In univariate linear regression analysis, the BCVAs 6 months after the surgery showed better preoperative BCVAs (p < 0.001) and a thinner central subfield macular thickness (p = 0.001). In multivariate linear regression analysis, the BCVA at 6 months after the surgery showed significant improvement compared with preoperative BCVA values (p < 0.001).Conclusions: High myopia patients whose axial length differences exceeded 2 mm showed improved VA after cataract surgery.
