ABSTRACT Purpose: To investigate periostin and collagen I expression during a scleral remodeling in myopic eyes and to determine their role in collagen remodeling of the myopic sclera. Methods: Fifty one-week-old guinea pigs were divided into the control and form-deprivation myopia (FDM) groups. The eyes of animals in the form-deprivation myopia group were covered for 2, 4, and 8 weeks, or were covered for 4 weeks and then uncovered for 2 weeks. The diopters and axial lengths in the eyes in each group of guinea pigs were measured. Immunohistochemistry and reverse transcription polymerase chain reaction were used to detect ...
To describe a pattern of combined exotropia and hypotropia in patients with unilateral high myopia and to suggest a surgical approach for their management.
Conclusion: Choroidal ganglioneuroma is rare. To our knowledge, no bilateral cases have been described in the literature. Major clinical features include a rapid increase in axial length, diffuse choroidal thickening, hyper-reflectivity in the choroid on optical coherence tomography, and loss of choroidal vasculature on ICGA. The current report provides multimodal imaging of choroidal ganglioneuroma for the first time and can be valuable for early diagnosis. PMID: 32454990 [PubMed]
Authors: Xiong F, Tu J, Mao T, Yu L, Lin N, Liao H Abstract Myopia is a common cause of visual impairment worldwide. Choroidal thickness (ChT) reflects the characteristic changes in myopic children and may be used as an important index of myopia. The purpose of this study was to investigate ChT and its distribution across the posterior pole in young myopic Chinese patients using enhanced depth imaging optical coherence tomography (EDI-OCT) and to explore the factors associated with it. A total of 402 myopic Chinese patients aged 6-16 years who underwent complete ophthalmic examinations, including those for axial le...
Conclusion: Significant differences in relative peripheral refraction were found between the atropine group and its controls. The findings suggested that the eyes that received atropine may have a less prolate shape and thus explain why using atropine is effective in controlling myopia progression. PMID: 32454988 [PubMed]
CONCLUSION: Ultra-wide field fluorescein angiography revealed various fluorescence features in the periphery of normal eyes, providing a basis for interpreting normal and pathological changes in peripheral retina and an important reference for clinical work.

CONCLUSIONS: Our findings are suggestive that SNTB1 is associated with high myopia in a Han Chinese population. PMID: 32452213 [PubMed - as supplied by publisher]
