Amblyopia and Refractive Status in Congenital Ptosis: The Effect and Timing of Surgical Correction.
Wu X, Zhang J, Ding X, Cao Y, Zhu X, Li R, Li L, Lin M, Li J. Wu X, et al. Ann Plast Surg. 2021 Jul 1;87(1):49-53. doi: 10.1097/SAP.0000000000002677. Ann Plast Surg. 2021. PMID: 33538502

The number of cases of amblyopia and strabismus was reduced, as was the percentage of cases of with-the-rule astigmatism (P < 0.05). CONCLUSION: Congenital ptosis can result in refractive error, strabismus, and amblyopia, which could seriously impai

RESULTS: Among 4040 Vision in Preschoolers Study participants overrepresenting children with vision disorders, 687 (17%) had astigmatism, and most (83.8%) had with-the-rule astigmatism. In multivariate analyses, African American (OR, 1.65; 95% CI, 1.22 …

Refractive development in individuals with ocular and oculocutaneous albinism.
Verkicharla P, Thakur S, Kammari P, Dhakal R, Das AV. Verkicharla P, et al. Int Ophthalmol. 2022 Jul;42(7):2007-2015. doi: 10.1007/s10792-021-02165-6. Epub 2022 May 19. Int Ophthalmol. 2022. PMID: 35587842
Irrespective of the albinism type, with-the-rule (70%) astigmatism was the most prevalent compared to other types of astigmatism. The frequency of with-the-rule astigmatism was significantly high in the presence of nystagmus compared to individuals wit …
