To determine the recovery of structural and functional corneal sensory nerves within the LASIK flap in order to provide insight to more proximal corneal reinnervation and symptoms post-LASIK.

Twenty participants underwent femtosecond LASIK with a superior flap hinge. Ocular Comfort Index in Chinese (OCI-C), Cochet-Bonnet esthesiometry, and in vivo confocal microscopy were conducted before surgery and 1week, 1-, 3-, and 6-months post-LASIK to measure symptoms, corneal sensitivity, nerve fiberdensity, width, and the numberofinterconnections within the flap (central and mid-temporal regions), and next to the superior flap hinge. Linear mixed models were used to compare differences between corneal regions at each time point post-LASIK and changes over time post-LASIK. Spearman's correlation tests were used to examine the associations between variables post-LASIK.

The least reduction in sensitivity (P < 0.03) and in nerve fiber density (P < 0.02) was found near the flap hinge compared to other regions, but no regional differences were found in nerve fiber width and interconnections. Nerve fiberdensity and the number of interconnections at all regions within the flap recovered over time (P < 0.02). The recovery of corneal sensitivity and nerve fiber width was only seen at the central and temporal regions (P < 0.04). No association was found between sensitivity and nerve parameters, but a higher OCI-C score was associated with a lower nerve fiber density near the hinge (r =  - 0.43, P = 0.003) over time post-LASIK.

Corneal sensitivity and density are preserved in the hinge, but this preservation of the corneal nerve damage does not affect the nerve morphology.

To estimate the clinical characteristics of retinal arterial macroaneurysms (RAM) and evaluate the prognosis of different interventions.

This study is a meta-analysis. The databases PubMed, EMBASE, and Ovid from inception to January 2021 were searched to identify the relevant studies. R software version 3.6.3 was used to perform the statistical analyses. Results in proportion with 95% confidence interval were calculated by means of Freeman-Tukey variant of arcsine square transformation.

Sixty-nine studies involving 1332 patients were finally included. The pooling results indicated that 91% (95% CI [88 ~ 94%]) of the RAM patients were over sixty, 73% (95% CI [68 ~ 77%]) were female, and 73% (95% CI [66 ~ 79%]) have hypertension. By observation, the RAM closure rate was 64% (95% CI [39 ~ 86%]), the visual acuity (VA) improved in 55% (95% CI [40 ~ 71%]) of the patients, and the VA of 64% (95% CI [54 ~ 74%]) hemorrhagic versus 27% (95% CI [15 ~ 41%]) exudative patients improved significantly. By laser, the ng laser or anti-VEGF treatments get higher closure rate and better visual prognosis than those with observation alone. Hemorrhagic RAM have a better visual prognosis by observation or laser treatment, while exudative RAM have a better visual prognosis by anti-VEGF treatment.

This study evaluated the safety and efficacy of Bowman's membrane electrocautery in blind painful eyes with bullous keratopathy not amenable to corneal transplantation.

Eleven eyes of 11 subjects with painful bullous keratopathy and poor visual potential who underwent electrocautery of Bowman's membrane at a tertiary referral ophthalmology clinic were reviewed retrospectively. Subject demographics and preoperative and postoperative data were collected, including description of pain, slit lamp biomicroscopy, best corrected visual acuity, topical medication use, and complications. Efficacy of the procedure on pain reduction, bullae resolution, and topical medication use were assessed at post-operative visits. Safety was also evaluated based on any complications.

Bowman's membrane electrocautery effectively resolved bullae in all eyes examined up to 6months postoperatively; however, 2 eyes had recurrence by 1year. Mean age at the time of surgery was 69.8years and mean duration of follow-up was 15.4months. Pain reduction was achieved in all eyes at 1month, but 1 subject had pain recurrence by 6months and another by 1year. The median number of drops per day decreased from 6 preoperatively to 1.7 at 6months. Two subjects who had underlying advanced ophthalmic disease had a mild reduction in vision.

Bowman's membrane electrocautery is a safe and minimally invasive procedure for the management of painful bullous keratopathy in eyes with low vision potential and not amenable to corneal transplantation. Duration of effect appears to last at least 6months and up to 3years post-procedure.

To report on the factors associated with severe vision loss from fireworks-related ocular trauma during celebrations, including festivals.

Tertiary eye care hospitals in 5 countries and private ophthalmology practices in the Netherlands. Patients included received treatment for fireworks-related ocular trauma during celebrations. Demographic and clinical data for patients affected were analyzed and associations with severe vision loss reported.

Of 388 patients, 71 (18.3 %) had severe vision loss (worse than 6/60) at 4-week follow-up due to fireworks-related ocular trauma. Mean age overall was 20.6 years (range 2 to 83 years), and there was a male predominance of 41. Clinical factors associated with severe vision loss included penetrating injury (OR 4.874 [95% CI 1.298-18.304; p = 0.02]) and lens injury (OR 7.023 [95% CI 2.378-20.736; p = 0.0004]). More patients with closed-globe injuries (CGIs) had improved vision after 4 weeks (OR 3.667, 1.096-12.27) compared to those with open-globe injuries (OGI) (p = 0.035). Eye protection use was reported by 7 patients, and 39.4% patients < 18 years were unsupervised by an adult at the time of injury.

Severe vision loss from fireworks-related ocular trauma occurred during celebrations in a variety of countries and was associated with penetrating and/or lens injury and poor presenting vision. New initiatives are needed to prevent severe vision loss associated with these injuries.

To compare the effects of ciclosporine A (2%) eye drop and tacrolimus (0.03%) eye ointment on children with vernal keratoconjunctivitis (VKC) who were not responding to corticosteroid eye drops.

A prospective comparative study was carried out on children who were diagnosed with refractory VKC at the ophthalmology clinic in Benha University, Delta area, Egypt, during the period from October 2019 to February 2020.

Fifty-nine patients completed this study. Regarding the individual symptom score, redness, burning, photophobia, and foreign body sensation were significantly reduced in the tacrolimus group compared to those in the ciclosporine A group during the 1st week (p < 0.05). Moreover, the tacrolimus group showed a statistically significant reduction in burning and foreign body sensation at the 4th week (both p = 0.032), and in redness and burning sensation at the 12th week compared to those in the ciclosporine A group (p = 0.005 and 0.048, respectively). The tacrolimus group showed significantly lowe A 2% eye drops was observed. Moreover, long-term medication for refractory cases is needed to control inflammation. Overall, our finding suggested that ciclosporine A eye drops and tacrolimus eye ointment could be considered as corticosteroid-sparing drugs in the management of children with refractory VKC.

IgA-dominant infection-associated glomerulonephritis is well-documented in adults but has not been studied in depth in children. We assessed the incidence of pediatric IgA-dominant infection-associated glomerulonephritis and clinical and kidney biopsy findings.

Pediatric native kidney biopsies over a 10-year period with IgA dominance, strong C3, and findings indicative of infection-associated etiology were identified.

We identified 9 cases of IgA-dominant infection-associated glomerulonephritis, 0.8% of pediatric native kidney biopsies. Seven patients presented with elevated creatinine. All had hematuria and proteinuria. Eight patients had clinical evidence of infection one each with central port infection by methicillin-sensitive Staphylococcus aureus, recurrent streptococcalpharyngitis and recent otitis media, streptococcalpharyngitis demonstrated 8months after biopsy, suspected streptococcalscalded skin syndrome, and viral gastroenteritis, and three with serologic evidence of Streptococcal infection but no identified site of infection. All but one patient experienced short-term normalization of creatinine and resolution of proteinuria, though two eventually progressed to kidney failure one 3years later due to progressive disease and one 11years later due to focal segmental glomerulosclerosis without concurrent immune deposits.

Pediatric IgA-dominant infection-associated glomerulonephritis is rare, and generally has a favorable prognosis, contrasting that seen in adults with severe comorbidities. A higher resolution version of the Graphical abstract is available as Supplementary.

The grading of urinary tract dilatation (UTD) on postnatal sonography is a fundamental step to establish rational management for infants with antenatal hydronephrosis (ANH). The aim of this study was to compare the prediction accuracy of UTD grading systems for relevant clinical outcomes. In addition, we propose a refinement of the UTD classification by adding quantitative measurements and evaluate its impact on accuracy.

Between 1989 and 2019, 447 infants diagnosed with isolated AHN were prospectively followed. The events of interest were surgical interventions and kidney injury. Comparison of performance of the grading systems and the impact on the accuracy of a modified UTD classification (including the size of the kidney parenchyma) was assessed by the area under the receiver-operating characteristic curve (AUC).

Of 447 infants, 131 (29%) underwent surgical intervention and 26 (5.8%) had developed kidney injury. The median follow-up time was 9years (IQ range, 7-12years). The performance for detectincation might increase the accuracy for predicting infants who may develop kidney injury.
