Purpose to explore the potential consequences of the COVID-19 lockdown on the prevalence of myopia among Italian children aged 5–12 years. Materials and Methods retrospective multicenter study conducted in Italy. Population: children aged 5–12. Selection: random selection of children who received an eye exam between 2016 to 2021. Inclusion criteria: healthy children presenting for a routine eye exam. Exclusion criteria: presence of ocular comorbidities other than refractive error, such as blepharoptosis, media opacities, corneal or retinal dystrophies, strabismus, amblyopia, or concurrent therapy with atropine 0.01%. Outcome measure: age and spherical equivalent (SE) measured in diopters (D) in the right eye (RE) in cycloplegia. Statistical analysis: ANOVA test. Results total of 803 children. In the years prior to COVID-19, the mean SE ± SD of healthy age-school children was: 0.54 ± 1.49 D in 2016; 0.43 ± 1.84 D in 2017; 0.34 ± 1.41 D in 2018; 0.35 ± 1.75 D in 2019 (ANOVA, p = .659). In 2021, the mean SE changed to −0.08 ± 1.44 D (ANOVA, p = .005). Mean age was comparable in all groups (ANOVA, p = .307). The prevalence of myopes (SE ≤−0.5D) and hyperopes (SE ≥ 2D) was respectively 24.10% and 9.64% among children aged 60–96 months, and 63.86% and 6.02% among children aged 97–144 months. These values represent a statistically-significant increase in the number of myopes (Chi-square, p = .016) and decrease in the number of hyperopes (Chi-square, p = .001), as compared to previous years (.06 and.48 respectively). Conclusion this retrospective study shows a statistically-significant decrease in the mean SE in children aged 5–12 in the year following the COVID-19 lockdown. The percentage of myopes has increased significantly, while the percentage of hyperopes has decreased. The lifestyle changes caused by the lockdown led children to spend more time on near-work activities and digital devices, and less time outdoors. These are known risk factors for the development and progression of myopia. Studies in different countries are encouraged.

Anterior capsule contraction syndrome (ACCS) is a rare, late complication of cataract surgery, associated with impairment of visual function. In this paper, we describe a new surgical technique to treat ACCS by femtosecond laser procedure. The femtosecond laser was used to perform an anterior capsulotomy with a customized size, in order to avoid IOL damage. After ophthalmic viscosurgical device injection in the anterior chamber, the anterior capsule flap was separated from the IOL surface by gentle hydrodissection. This manoeuvre enabled an easy and safe removal of the fibrotic material by vitreal microscissors. Our technique allowed a complete removal of the fibrotic material and opening of the capsule, with immediate complete visual acuity recovery without IOL damage. In conclusion, femtosecond laser appears to be safe and effective for treatment of ACCS with long-lasting efficacy.

Background Fabry disease (FD) is a rare X-linked, lysosomal storage disorder caused by mutations in the alpha-galactosidase gene and characterized by neurological, cutaneous, renal, cardiovascular, cochleo-vestibular and ocular manifestations. The aim of this study is to characterize morphological, functional and autophagy-lysosome pathway alterations of the ocular surface in FD patients. Methods Eleven subjects with a diagnosis of FD and fifteen healthy control subjects were examined. All patients underwent ocular surface slit lamp examination, corneal aesthesiometry and in vivo confocal laser-scanning microscopy (CCM). Conjunctival impression cytology was performed in six FD patients and six controls, to assess for expression of two markers of the autophagy-lysosome pathway: the microtubule-associated protein light chain 3 (LC3) and lysosome-associated membrane protein 2 (LAMP2). Results Cornea verticillata and increased conjunctival vessel tortuosity were detected respectively in 67% and 33% of patients with FD. Compared with healthy subjects, patients affected by FD showed a significant reduction in corneal nerve fiber length, density and nerve branching on CCM and a significantly increased expression of LC3 on conjunctival impression cytology (p < 0.001). No changes were observed in the conjunctival expression of LAMP2 between the two groups. Conclusions This study shows that FD is associated with ocular surface alterations including corneal and conjunctival morphology, innervation and vascularization changes. Our data demonstrate an increased expression of LC3 protein in patients with FD, suggesting that alteration of the autophagy-lysosome pathway may play a role in the occurrence of ocular manifestations.
