Association between maternal fasting glucose levels throughout pregnancy and preschoolers' refractive errors
CONCLUSIONS: High level of fasting plasma glucose trajectories during pregnancy has been observed to be associated with 6-year-old children's refractive error, hypermetropia and astigmatism. The first and the second trimesters may be critical periods for the effects of maternal blood glucose on children's vision. The long-term effect of maternal glucose metabolism on children's visual development deserves further study.PMID:38625056 | DOI:10.1210/clinem/dgae247 (Source: The Journal of Clinical Endocrinology and Metabolism)

Refractive changes associated with oculoplastic surgeries: A scoping review
CONCLUSIONS: Based on the findings of this study, there is no evidence to suggest clinically significant refractive changes following oculoplastic surgeries. The most notable changes may occur after surgery for severe ptosis; however, further research is needed to confirm this observation.PMID:38623746 | DOI:10.1177/11206721241247422 (Source: European Journal of Ophthalmology)

Ophthalmic features of Lamb-Shaffer syndrome: a case series
We present a case series of 6 pediatric patients with LSS and describe its ophthalmic manifestations. Strabismus was present in 5 patients, with exotropia being most common. All subjects had significant refractive errors; 5 had astigmatism of at least 2 D. All patients had optic nerve abnormalities, including pallor (4), hypoplasia (2), and anomalous appearance (1), with retinal nerve fiber layer thinning demonstrated in a single subject.

Higher order aberrations in keratoconus
ConclusionsEarly diagnosis can lead to early treatment and may allow for arresting progression, thereby improving the long-term prognosis. With the acceleration of refractive surgery, it is important to identify patients with keratoconus, as they are usually contraindicated for refractive surgery. (Source: International Ophthalmology)

Femtosecond laser-assisted astigmatic keratotomy versus toric IOL implantation for correcting astigmatism in cataract patients: a systematic review and meta-analysis with trial sequential analysis
CONCLUSIONS: For cataract patients, both FSAK and toric IOLs are effective methods for correcting astigmatism. However, toric IOLs offer less postoperative astigmatism and result in better postoperative UDVA compared with FSAK. In vector analysis of astigmatism, toric IOLs can also produce higher TIA and SIA. Additionally, neither method is associated with severe untreatable complications. Therefore, the conclusion is that toric IOLs are the preferred choice for astigmatism correction in cataract patients and FSAK serves as a viable alternative when toric IOLs are contraindicated.PMID:38575199 | DOI:10.1136/bjo-2024-325195...
