Review
BACKGROUND
The coronavirus disease 2019 (COVID-19) pandemic has been the most challenging health problem in the last 2 years. Post-COVID-19 multisystem inflammatory syndrome of children (MIS-C) is a severe post-COVID-19 complication in pediatric patients. Ocular manifestations may be the first presentation of MIS-C, wherein prompt treatment may improve outcomes. In this systematic review, we aimed to summarize the acute and sub-acute ocular manifestations in pediatric patients with laboratory-confirmed COVID-19.
METHODS
We included all online primary studies, with no language restriction and published between January 1, 2019 and November 18, 2020, reporting any acute or sub-acute ocular manifestations in children with laboratory-confirmed COVID-19. PubMed/MEDLINE was searched using the following MeSH and Emtree terms: "eye," "ophthalmologic," "ocular," "vision," "conjunctivitis," "severe acute respiratory syndrome coronavirus 2," "SARS-CoV-2," "corona," "2019-nCoV," "COVID19," and "COVID." The eligibility and quality of the selected records were assessed by two independent reviewers as per the Cochrane Handbook for Systematic Review.
RESULTS
A total of 1,192 records were identified electronically. Seven papers were extracted from the reference lists of the eligible records. Thirty-six papers met the inclusion criteria and were categorized into two subgroups according to acute or sub-acute presentation of ocular manifestations. Among 463 pediatric patients with COVID-19, 72 (15.5%) had acute ocular manifestations. There was one patient with central retinal vein occlusion and another with photophobia and diplopia associated with meningoencephalitis. Among 895 pediatric patients with post-COVID-19 MIS-C, 469 (52.4%) had ocular manifestations, which only included non-purulent conjunctivitis.
CONCLUSIONS
Ocular manifestations have been reported in less than one-fifth of pediatric patients with acute COVID-19. Furthermore, conjunctivitis was the only ocular manifestation reported in half of the patients with MIS-C, and it may be missed easily due to its non-purulent nature. During the COVID-19 pandemic, pediatricians and health workers must remain vigilant for early detection of signs of this potentially fatal post-COVID-19 inflammatory syndrome.

To evaluate the efficacy and safety of atropine for slowing myopia progression and to investigate whether the treatment effect remains constant with continuing treatment. Studies were retrieved from MEDLINE, EMBASE, and the Cochrane Library from their inception to May 2021, and the language was limited to English. Randomized controlled trials (RCTs) and cohort studies involving atropine in at least one intervention and placebo/non-atropine treatment in another as the control were included and subgroup analysis based on low dose (0.01%), moderate dose (0.01%-<0.5%), and high dose (0.5-1.0%) were conducted. The Cochrane Collaboration and Newcastle-Ottawa Scale were used to evaluate the quality of RCTs and cohort studies, respectively. Twelve RCTs and fifteen cohort studies involving 5,069 children aged 5 to 15 years were included. The weighted mean differences in myopia progression between the atropine and control groups were 0.73 diopters (D), 0.67 D, and 0.35 D per year for high-dose, moderate-dose, and low-dose atropine, respectively (χ = 13.76; = 0.001, = 85.5%). After removing studies that provided extreme findings, atropine demonstrated a significant dose-dependent effect on both refractive change and axial elongation, with higher dosages of atropine resulting in less myopia progression ( = 0.85; = 0.004) and less axial elongation ( = -0.94; = 0.005). Low-dose atropine showed less myopia progression (-0.23 D; = 0.005) and less axial elongation (0.09 mm, < 0.001) in the second year than in the first year, whereas in high-dose atropine more axial elongation (-0.15 mm, = 0.003) was observed. The higher dose of atropine was associated with a higher incidence of adverse effects, such as photophobia with an odds ratio (OR) of 163.57, compared with an OR of 6.04 for low-dose atropine and 8.63 for moderate-dose atropine ( = 0.03). Both the efficacy and adverse effects of atropine are dose-dependent in slowing myopia progression in children. The efficacy of high-dose atropine was reduced after the first year of treatment, whereas low-dose atropine had better efficacy in a longer follow-up period.

BACKGROUND
There is a high variability in the use of postoperative eye protection among ophthalmologists. Postoperative eye protection treatment modalities include an eye shield, an eye patch, an ocular bandage, and instant vision. The aim of this study was to review and compare the evidence on the various options for eye protection.
METHODS
A systematic literature search was conducted, and original comparative articles that reported on subjective symptoms (e.g., foreign-body sensation, photophobia, tearing, and pain) and postoperative outcomes (e.g., tear film breakup time, best-corrected visual acuity, etc.) after usage of an eye protection method were included.
RESULTS
Overall, 598 eyes across 8 articles were included. Included studies investigated ocular bandages (n = 6), eye patches (n = 4), instant vision (n = 2), and eye shields (n = 1) postoperatively. In 5 studies, patients receiving ocular bandages self-reported symptoms, including pain (n = 3), foreign-body sensation (n = 4), photophobia (n = 3), and tearing (n = 3), at a reduced or equivalent rate compared with other treatment modalities. With the ocular bandage, 3 studies reported increased tear film breakup time, and 1 study reported improvements in corneal wound healing compared with a control group. Two studies reported reduced tear film breakup time for the eye patch relative to the ocular bandage, and another study reported reduced tear film breakup time for instant vision compared with the eye patch.
CONCLUSIONS
Patient-reported symptoms are acutely reduced for patients receiving an ocular bandage relative to instant vision following cataract surgery. Patients prefer receiving some form of postoperative protection as opposed to instant vision.

By reviewing the existing clinical studies about visual snow (VS) as a symptom or as part of visual snow syndrome (VSS), we aim at improving our understanding of VSS being a network disorder. Patients with VSS suffer from a continuous visual disturbance resembling the view of a badly tuned analog television (i.e., VS) and other visual, as well as non-visual symptoms. These symptoms can persist over years and often strongly impact the quality of life. The exact prevalence is still unknown, but up to 2.2% of the population could be affected. Presently, there is no established treatment, and the underlying pathophysiology is unknown. In recent years, there have been several approaches to identify the brain areas involved and their interplay to explain the complex presentation. We collected the clinical and paraclinical evidence from the currently published original studies on VS and its syndrome by searching PubMed and Google Scholar for the term visual snow. We included original studies in English or German and excluded all reviews, case reports that did not add new information to the topic of this review, and articles that were not retrievable in PubMed or Google Scholar. We grouped the studies according to the methods that were used. Fifty-three studies were found for this review. In VSS, the clinical spectrum includes additional visual disturbances such as excessive floaters, palinopsia, nyctalopia, photophobia, and entoptic phenomena. There is also an association with other perceptual and affective disorders as well as cognitive symptoms. The studies that have been included in this review demonstrate structural, functional, and metabolic alterations in the primary and/or secondary visual areas of the brain. Beyond that, results indicate a disruption in the pre-cortical visual pathways and large-scale networks including the default mode network and the salience network. The combination of the clinical picture and widespread functional and structural alterations in visual and extra-visual areas indicates that the VSS is a network disorder. The involvement of pre-cortical visual structures and attentional networks might result in an impairment of "filtering" and prioritizing stimuli as top-down process with subsequent excessive activation of the visual cortices when exposed to irrelevant external and internal stimuli. Limitations of the existing literature are that not all authors used the ICHD-3 definition of the VSS. Some were referring to the symptom VS, and in many cases, the control groups were not matched for migraine or migraine aura.

Review
PURPOSE
To review all case series of refractive corneal inlay implantation: Flexivue (Presbia, Netherlands), Invue (BioVision, Brügg, Switzerland) and Icolens (Neoptics, Hünenberg, Switzerland) performed in presbyopia patients and to evaluate the reported visual outcomes. In addition, our aim is to provide assessment for complications and to report the satisfaction rates.
METHODS
PubMed, Web of Science and Scopus databases were consulted using "refractive corneal inlay", "Flexivue Inlay", "Invue Inlay" and "Icolens inlay" as keywords. 147 articles were found, and they were assessed considering the inclusion and exclusion criteria. After filtering, this systemic review included ten articles, published between 2011 and 2020.
RESULTS
308 eyes from 308 participants were enrolled in this systematic review. Mean maximum follow-up was 13.9 months. Nine of the ten case series included used femtosecond laser for the corneal pocket creation. Mean pocket depth was 293.75 µm. 77.5% of the eyes reported a postoperative uncorrected near visual acuity of 20/32 or better, and 19.20% of the inlay-implanted eyes achieved an uncorrected distance visual acuity of 20/20 or better. The most prominent complications were halos, pain, photophobia, and poor distance visual acuity. 27 eyes (8.7%) had to be explanted due to complications, such as near-distance spectacle dependence or blurred distance vision.
CONCLUSION
Refractive corneal inlay outcomes demonstrated high efficacy, safety, and satisfaction rates. Furthermore, it is a reversible technique. However, the findings must be viewed with caution due potential conflict of interest. Further research with higher sample size is needed to validate these findings.

Meta-Analysis Review
Ocriplasmin for treatment of vitreomacular traction and macular hole: A systematic literature review and individual participant data meta-analysis of randomized, controlled, double-masked trials.
Ocriplasmin is used to treat vitreomacular traction (VMT), with or without full-thickness macular hole (MH). We systematically reviewed the evidence on ocriplasmin's effect on vitreomacular adhesion resolution (VMAR), MH closure, vitrectomy, and best-corrected visual acuity (BCVA) and investigated the effect of baseline covariates on outcome. We applied individual participant data meta-analyses to the entire population and to subgroups defined by MH or epiretinal membrane (ERM) presence. Safety data were pooled and tabulated. Five randomized controlled trials (1,067 participants) were included. Six months after treatment, ocriplasmin achieved higher rates of VMAR and MH closure versus control, lowered vitrectomy odds, and increased the likelihood of a ≥10-letter BCVA increase. VMAR rates were lower when ERM, broad VMA (> 1500 µm), diabetic retinopathy, or pseudophakia were present and higher in younger participants, women, and eyes with MHs. Ocriplasmin-treated participants experienced more short-term visual impairment that was not predictive of final BCVA, as well as vitreous floaters, photopsia, photophobia, eye pain, blurred vision, and dyschromatopsia. The most common serious adverse events for ocriplasmin and control, respectively, were MH progression (22.5%, 17.3%), new MH (1.5%, 3.4%) and retinal detachment (0.8%, 1.2%). Ocriplasmin promotes VMAR and MH closure. Transient visual phenomena are not uncommon.

Meta-Analysis
BACKGROUND AND OBJECTIVE
There are five headache disorders composing the trigeminal autonomic cephalalgias (cluster headache, paroxysmal hemicrania, short-lasting unilateral neuralgiform headache attacks with conjunctival injection and tearing (SUNCT), short-lasting unilateral neuralgiform headache attacks with cranial autonomic symptoms (SUNA), and hemicrania continua). Little is known about these disorders in the pediatric population. The objectives of this study are to report the full age ranges of pediatric trigeminal autonomic cephalalgias and to determine if pediatric-onset trigeminal autonomic cephalalgias display similar signs and symptoms as adult onset.
METHODS
Search criteria in Medline Ovid, Embase, PsycINFO, and Cochrane Library were created by a librarian. The remainder of the steps were independently performed by two neurologists using PRISMA guidelines. Inclusion criteria for titles and abstracts were articles discussing cases of trigeminal autonomic cephalalgias with age of onset 18 or younger, as well as any epidemiological report on trigeminal autonomic cephalalgias (as age of onset data was often found in the results section but not in the title or abstract). Data extracted included age of onset, sex, and International Classification of Headache Disorders criteria for trigeminal autonomic cephalalgias (including pain location, duration, frequency, autonomic features, restlessness) and some migraine criteria (photophobia, phonophobia, and nausea). Studies that did not meet full criteria for trigeminal autonomic cephalalgias were examined separately as "atypical trigeminal autonomic cephalalgias"; secondary headaches were excluded from this category.
RESULTS
In all, 1788 studies were searched, 86 met inclusion criteria, and most (56) examined cluster headache. In cluster headache, onset occurred at every pediatric age (range 1-18 years) with a full range of associated features. Autonomic and restlessness features were less common in pediatric patients, while migrainous features (nausea, photophobia, and phonophobia) were found at similar rates. The sex ratio of pediatric-onset cluster headache (1.8, 79 male and 43 female) may be lower than that of adult-onset cluster headache. Data for other trigeminal autonomic cephalalgias, while more limited, displayed most of the full range of official criteria. The data for atypical trigeminal autonomic cephalalgias were also limited, but the most common deviations from the official criteria were abnormal frequencies and locations of attacks.
CONCLUSIONS
Trigeminal autonomic cephalalgias can start early in life and have similar features to adult-onset trigeminal autonomic cephalalgias. Specifically, pediatric-onset cluster headache patients display the full range of each criterion for cluster headache (except maximum frequency of six instead of eight attacks per day). However, cranial autonomic features and restlessness occur at a lower rate in pediatrics. Additional information is needed for the other trigeminal autonomic cephalalgias. As for expanding the ICHD-3 criteria for pediatric-onset trigeminal autonomic cephalalgias, we have only preliminary data from atypical cases, which suggests that the frequency and location of attacks sometimes extend beyond the official criteria. This study was registered as a systematic review in PROSPERO (registration number CRD42020165256).

Meta-Analysis
SIGNIFICANCE
This study reports the prevalence and relative risk of photophobia in patients with traumatic brain injury (TBI).
OBJECTIVES
This study aimed to conduct a systematic review and meta-analysis to determine the prevalence and relative risk of photophobia in patients with TBI.
DATA SOURCES
Three databases were used for literature search: PubMed, EMBASE, and Cochrane Library.
STUDY APPRAISAL AND SYNTHESIS METHODS
Publications reporting the prevalence of photophobia after TBI in patients of any age were included. A series of meta-regression analyses based on a generalized linear mixed model was performed to identify potential sources of heterogeneity in the prevalence estimates.
RESULTS
Seventy-five eligible publications were identified. The prevalence of photophobia was 30.46% (95% confidence interval [CI], 20.05 to 40.88%) at 1 week after the injury. Prevalence decreased to 19.34% (95% CI, 10.40 to 28.27%) between 1 week and 1 month after TBI and to 13.51% (95% CI, 5.77 to 21.24%) between 1 and 3 months after the injury. The rapid decrease in the prevalence of photophobia in the first 3 months after a TBI injury was significant (P < .001). Three months post-TBI, the prevalence of photophobia leveled off to a near plateau with nonsignificant variability, increasing between 3 and 6 months (17.68%; 95% CI, 9.05 to 26.32%) and decreasing between 6 and 12 months since TBI (14.85%; 95% CI, 6.80 to 22.90%). Subgroup analysis of 14 publications that contained control data showed that the estimated risk ratio for photophobia was significantly higher in the TBI than in the control group during the entire 12 months after TBI.
CONCLUSIONS AND IMPLICATIONS OF KEY FINDINGS
This study demonstrates that photophobia is a frequent complaint after TBI, which largely resolves for many individuals within 3 months after the injury. For some patients, however, photophobia can last up to 12 months and possibly longer. Developing an objective quantitative methodology for measuring photophobia, validating a dedicated photophobia questionnaire, and having a specific photophobia International Classification of Diseases, Tenth Revision code would greatly improve data gathering and analysis.

Review
PURPOSE
With the recent increase in popularity of electronic cigarette use in the United States, its harmful effects are not only limited to smoke inhalation, but also to the possibility of e-cigarette device malfunction. The purpose of this review is to characterize oromaxillofacial trauma secondary to electronic cigarette device explosion.
METHODS
For this systematic review, PubMed and Embase were searched in October 2019 using the following search terms: e-cigarette burns, e-cigarette injury, and e-cigarette explosions, which yielded 400 studies. Basic science research, animal studies, non-English studies, and reports of non-oromaxillofacial injuries were excluded. Study subject demographics, mechanism of trauma, injury type, treatment, and sequelae were recorded and analyzed.
RESULTS
Of all studies, 20 studies met inclusion criteria, including 14 case reports and 6 case series, with a total of 21 study subjects. For cases that reported sex, 100% were male (20) with a mean age of 29.5 years. Most common lacerations and/or burns involved the lips (10/21), tongue (8/21), soft palate and/or hard palate (4/21), and nose (5/21). Thirteen subjects underwent surgeries including oral-maxillofacial surgery or dental implants (7/13), bone graft repair (3/13), open reduction and internal fixation for preservation of sinus outflow tracts (2/13), foreign body removal from the cervical spine (1/13), and iridectomy (1/13). Reported complications included bone loss secondary to traumatic fracture, tinnitus and hearing loss, lip paralysis secondary to persistent edema, major depressive disorder/ post-traumatic stress disorder, persistent sinusitis, photophobia, and bilateral axillary and hand contractures.
CONCLUSIONS
Electronic cigarette device malfunction and explosion carries great risk for acute oromaxillofacial trauma that may be disfiguring. With the increasing popularity of electronic cigarette use, clinicians and patients should be advised regarding dangers of electronic cigarette use.

PURPOSE
To systematically review the literature on the treatment of vernal keratoconjunctivitis (VKC) in children and young adults and conduct comparative efficacy analysis on clinical signs and symptoms using network meta-analyses.
METHODS
We systematically searched the databases PubMed/MEDLINE, EMBASE, Cochrane Central and Web of Science on 21 October 2019 for randomized controlled trials (RCT). Studies considered had patients with VKC < 20 years of age randomized into either intervention (any medical intervention) or comparator (active treatment, placebo treatment or non-treatment control), where pre-defined outcomes (data from ≥2 weeks and as close as possible to 2 months) of symptoms (itching, tearing, photophobia and foreign body sensation) and signs (hyperaemia, punctate keratitis, Horner-Trantas dots and macropapillae) were reported. Risk of bias within studies was evaluated using the Cochrane risk of bias tool. Comparisons were made using network meta-analyses.
RESULTS
We identified 39 studies with data on 2046 individuals. Twenty-three studies were eligible for quantitative analyses. None were systemic therapy. Temporal trend analysis showed that an initial focus on topical mast cell stabilizers turned to a focus on calcineurin inhibitors and a more diverse variety of pharmacological strategies. Studies varied in population, treatment duration and quality. The quantitative analysis revealed that efficacy of different therapies differed substantially across important clinical signs and symptoms, but there was a general trend of superior efficacy when using topical corticosteroids with stronger efficacy of the more potent corticosteroids.
CONCLUSION
We provide an overview of RCTs comparing the efficacy of treatments for VKC in children and young adults, which we find differs across symptoms and signs. Overall, we saw a general trend of superior efficacy with topical corticosteroids. However, our findings highlight the need for better studies, consensus on core outcomes and potential for individualized therapy.
