There is significant variation in treatment parameters when treating the infraorbital region. Thorough knowledge of these pertinent factors, choice of the optimal filling material, and proper understanding of the anatomy of this unforgiving region will contribute to a safe, effective, and natural result. We aim to conduct a systematic review of published literature related to soft tissue fillers of the tear trough and infraorbital region. A search of published literature was conducted in accordance with PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines and included PubMed, Embase, and Science Direct databases. The Medical Subject Headings (MeSH) terms used were "tear trough" OR "infraorbital" AND "dermal filler" OR "hyaluronic acid" OR "poly-L-lactic acid" OR "calcium hydroxyapatite" OR "Restylane" OR "Radiesse" OR "Perlane" OR "Juvéderm" OR "Belotero." Different combinations of these key terms were used. The initial search identified 526 articles. Six additional articles were identified through references. Two-hundred twenty-five duplicates were removed. A total of 307 studies were screened by title and abstract and 258 studies were eliminated based on inclusion and exclusion criteria. Forty-nine articles underwent full-text review. The final analysis included 23 articles. Patient satisfaction was high, and duration of effect ranged from 8 to 12 months. Restylane was most commonly used. Injection technique varied, but generally involved placing filler pre-periosteally, deep to orbicularis oculi muscle, anterior to the inferior orbital rim via serial puncture or retrograde linear threading with a 30-gauge needle. Topical anesthetic was most commonly used. Side effects were generally mild and included bruising, edema, blue-gray dyschromia, and contour irregularities. Nonsurgical correction of the tear trough deformity with soft tissue filler is a minimally invasive procedure with excellent patient satisfaction with long-lasting effects. It is essential to have a fundamental understanding of the relevant anatomy and ideal injection technique to provide excellent patient outcomes and prevent serious complications.

Dermatologic Surgery : Official... Jan 2021Periorbital hyperpigmentation (POH) is an aesthetic concern for patients. Etiologies of the condition include pigmentary, structural, vascular, and mixed causes.
BACKGROUND
Periorbital hyperpigmentation (POH) is an aesthetic concern for patients. Etiologies of the condition include pigmentary, structural, vascular, and mixed causes.
OBJECTIVE
To systematically review the current literature for treatment of POH.
METHODS
A systematic literature review was performed on PubMed. Search terms included "infraorbital dark circles," "dark circles," "periorbital hyperpigmentation," "idiopathic hyperchromia AND orbital," "under-eye circles," "ICHOR (idiopathic cutaneous hyperchromia of the orbital region)," "dark circles" AND "treatment," and "filler" AND "dark circles."
RESULTS
A total of 39 studies were included. Effective treatments for POH include lasers, topical creams and serums, fillers, chemical peels, carboxytherapy, plasma-rich platelet injections, blepharoplasty, and normobaric oxygen.
CONCLUSION
Soft tissue fillers and autologous fat grafting are most effective in treating dark circles due to volume loss. Blepharoplasty surgery is best when excessive skin laxity is the underlying cause. Various topical creams and chemical peels are useful in treating pigment-based POH, whereas lasers are mildly to moderately beneficial for both vascular and pigment types. Given the scarcity of high-quality evidence supporting these results, recommendations should be interpreted selectively. Additional randomized clinical trials studying POH will be helpful.

Meta-Analysis Review
INTRODUCTION
The retina shares structural and functional similarities with the brain. Furthermore, structural changes in the retina have been observed in patients with schizophrenia spectrum disorders (SSDs). This systematic review and meta-analysis investigated retinal abnormalities and their association with clinical factors for SSD.
METHODS
Studies related to retinal layers in SSD patients were retrieved from PubMed, Scopus, Web of Science, Cochrane Controlled Register of Trials, International Clinical Trials Registry Platform, and PSYNDEX databases from inception to March 31, 2021. We screened and assessed the eligibility of the identified studies. EZR ver.1.54 and the metafor package in R were used for the meta-analysis and a random-effects or fixed-effects model was used to report standardized mean differences (SMDs).
RESULTS
Twenty-three studies (2079 eyes of patients and 1571 eyes of controls) were included in the systematic review and meta-analysis. The average peripapillary retinal nerve fiber layer (pRNFL) thickness, average macular thickness (MT), and macular ganglion cell layer-inner plexiform layer (GCL-IPL) thickness were significantly lower in patients than in controls (n = 14, 6, and 3, respectively; SMD = -0.33, -0.49, and -0.43, respectively). Patients also had significantly reduced macular volume (MV) compared to controls (n = 7; SMD = -0.53). The optic cup volume (OCV) was significantly larger in patients than in controls (n = 3; SMD = 0.28). The meta-regression analysis indicated an association between several clinical factors, such as duration of illness and the effect size of the pRNFL, macular GCL-IPL, MT, and MV.
CONCLUSION
Thinning of the pRNFL, macular GCL-IPL, MT, and MV and enlargement of the OCV in SSD were observed. Retinal abnormalities may be applicable as state/trait markers in SSDs. The accumulated evidence was mainly cross-sectional and requires verification by longitudinal studies to characterize the relationship between OCT findings and clinical factors.

Review
Ocular ischemic syndrome is a rare condition, which is caused by ocular hypoperfusion due to stenosis or occlusion of the common or internal carotid arteries. Atherosclerosis is the major cause of changes in the carotid arteries. Ocular ischemic syndrome is manifested as visual loss, orbital pain and, frequently, changes of the visual field, and various anterior and posterior segment signs. Anterior segment signs include iris neovascularization and secondary neovascular glaucoma, iridocyclitis, asymmetric cataract, iris atrophy and sluggish reaction to light. Posterior eye segment changes are the most characteristic, such as narrowed retinal arteries, perifoveal telangiectasias, dilated retinal veins, mid-peripheral retinal hemorrhages, microaneurysms, neovascularization at the optic disk and in the retina, a cherry-red spot, cotton-wool spots, vitreous hemorrhage and normal-tension glaucoma. Differential diagnosis of ocular ischemic syndrome includes diabetic retinopathy and moderate central retinal vein occlusion. Carotid artery imaging and fundus fluorescein angiography help to establish the diagnosis of ocular ischemic syndrome. The treatment can be local, for example, ocular (conservative, laser and surgical) or systemic (conservative and surgical treatment of the carotid artery). Since the condition does not affect the eyes alone, patients with ocular ischemic syndrome should be referred for consultation to the neurologist, vascular surgeon and cardiologist.

Meta-Analysis Review
BACKGROUND
Structural retinal imaging biomarkers are important for early recognition and monitoring of inflammation and neurodegeneration in multiple sclerosis. With the introduction of spectral domain optical coherence tomography (SD-OCT), supervised automated segmentation of individual retinal layers is possible. We aimed to investigate which retinal layers show atrophy associated with neurodegeneration in multiple sclerosis when measured with SD-OCT.
METHODS
In this systematic review and meta-analysis, we searched for studies in which SD-OCT was used to look at the retina in people with multiple sclerosis with or without optic neuritis in PubMed, Web of Science, and Google Scholar between Nov 22, 1991, and April 19, 2016. Data were taken from cross-sectional cohorts and from one timepoint from longitudinal studies (at least 3 months after onset in studies of optic neuritis). We classified data on eyes into healthy controls, multiple-sclerosis-associated optic neuritis (MSON), and multiple sclerosis without optic neuritis (MSNON). We assessed thickness of the retinal layers and we rated individual layer segmentation performance by random effects meta-analysis for MSON eyes versus control eyes, MSNON eyes versus control eyes, and MSNON eyes versus MSON eyes. We excluded relevant sources of bias by funnel plots.
FINDINGS
Of 25 497 records identified, 110 articles were eligible and 40 reported data (in total 5776 eyes from patients with multiple sclerosis [1667 MSON eyes and 4109 MSNON eyes] and 1697 eyes from healthy controls) that met published OCT quality control criteria and were suitable for meta-analysis. Compared with control eyes, the peripapillary retinal nerve fibre layer (RNFL) showed thinning in MSON eyes (mean difference -20·10 μm, 95% CI -22·76 to -17·44; p<0·0001) and in MSNON eyes (-7·41 μm, -8·98 to -5·83; p<0·0001). The macula showed RNFL thinning of -6·18 μm (-8·07 to -4·28; p<0·0001) in MSON eyes and -2·15 μm (-3·15 to -1·15; p<0·0001) in MSNON eyes compared with control eyes. Atrophy of the macular ganglion cell layer and inner plexiform layer (GCIPL) was -16·42 μm (-19·23 to -13·60; p<0·0001) for MSON eyes and -6·31 μm (-7·75 to -4·87; p<0·0001) for MSNON eyes compared with control eyes. A small degree of inner nuclear layer (INL) thickening occurred in MSON eyes compared with control eyes (0·77 μm, 0·25 to 1·28; p=0·003). We found no statistical difference in the thickness of the combined outer nuclear layer and outer plexiform layer when we compared MSNON or MSON eyes with control eyes, but we found a small degree of thickening of the combined layer when we compared MSON eyes with MSNON eyes (1·21 μm, 0·24 to 2·19; p=0·01).
INTERPRETATION
The largest and most robust differences between the eyes of people with multiple sclerosis and control eyes were found in the peripapillary RNFL and macular GCIPL. Inflammatory disease activity might be captured by the INL. Because of the consistency, robustness, and large effect size, we recommend inclusion of the peripapillary RNFL and macular GCIPL for diagnosis, monitoring, and research.

Review
The Purpose is to identify, through a systematic literature review, the current evidence regarding the effectiveness of topical insulin treatment in ocular surface pathologies. A literature search was implemented in Medline (Pubmed), Embase and Web Of Science medical indexing databases by using keywords such as "insulin" AND "cornea" OR "corneal" OR "dry eye" in published papers in English or Spanish within the last eleven years (2011-2022). Nine papers were identified with 180 participants from the United States, Spain, Ireland, Canada, Portugal and Malaysia, with persistent refractory epithelial defects and secondary to vitrectomy, whose extension of the lesion was from 3,75mm to 65.47mm. The preparation was dissolved with artificial tears and the insulin concentration ranged from 1 IU/ml to 100 IU/ml. In all cases, the resolution of the clinical picture was complete with a healing time from 2.5 days to 60.9 days, the latter being a secondary case to a difficult-to-control caustic burn. Topical insulin has been effective for the treatment of persistent epithelial defects. The intermediate action and low concentrations showed a shorter resolution time in neurotrophic ulcers and induced during vitreoretinal surgery.

Meta-Analysis Review
PURPOSE
To evaluate the long-term efficacy and safety of repeated low-intensity red light (RLRL) treatment for childhood myopia.
DESIGN
Systematic review and meta-analysis METHODS: We searched PubMed, Web of Science, CNKI, and Wanfang from inception to February 8, 2023. We used the RoB 2.0 and ROBINS-I tools to assess the risk of bias and then used a random-effect model to calculate the weighted mean difference (WMD) and 95% CIs. The primary outcomes were WMD in spherical equivalent refractive error (SER), WMD in axial length (AL), and WMD in subfoveal choroid thickness (SFChT). Subgroup analyses were performed to investigate the sources of heterogeneity based on variation in follow-up and study design. The Egger and Begg tests were used to assess publication bias. Sensitivity analysis was used to verify the stability.
RESULTS
This analysis included 13 studies (8 randomized controlled trials, 3 non-randomized controlled trials, and 2 cohort studies) involving 1857 children and adolescents. Eight studies met the meta-analysis criteria, and the WMD for myopia progression between RLRL and the control group was 0.68 diopters (D) per 6 months (95% CI = 0.38 to 0.97 D; I = 97.7%; P < .001) for SER change; -0.35 mm per 6 months (95% CI = -0.51 to -0.19 mm; I = 98.0%; P < .001) for AL elongation; and 36.04 µm per 6 months (95% CI = 19.61 to 52.48 µm; I = 89.6%; P < .001) for SFChT change.
CONCLUSIONS
Our meta-analysis shows that RLRL therapy may be effective for delaying the progression of myopia. The evidence is low certainty, and larger and better randomized clinical trials with 2-year follow-ups are needed to improve the existing state of knowledge to inform medical guidelines more comprehensively.

Review
BACKGROUND
Eustachian tube dysfunction (ETD) is the inability of the Eustachian tube (ET) to adequately perform at least one of its functions: to protect the middle ear from sources of disease, to ventilate the middle ear, and to help drain secretions away from the middle ear. There are a number of treatment options for ETD, but there is little consensus about management.
OBJECTIVES
To determine the clinical effectiveness of interventions for adult ETD and to identify gaps in the evidence to inform future research.
DATA SOURCES
Twelve databases were searched up to October 2012 for published and unpublished studies in English (e.g. MEDLINE from 1946, EMBASE from 1974, Biosis Previews from 1969 and Cumulative Index to Nursing and Allied Health Literature from inception). References of included studies, relevant systematic reviews and regulatory agency websites were checked.
REVIEW METHODS
A systematic review was undertaken. Controlled studies evaluating prespecified treatments for adult patients diagnosed with ETD were eligible. Uncontrolled studies with at least 10 participants were included for interventions where no controlled studies were found. Outcomes included change in symptoms severity/frequency (primary outcome), quality of life, middle ear function, hearing, clearance of middle ear effusion, early ventilation tube extrusion, additional treatment, adverse events and complications. All aspects of the review process were performed using methods to reduce reviewer error and bias. Owing to heterogeneous data, a quantitative synthesis could not be performed, and results were reported in a narrative synthesis.
RESULTS
Nineteen studies were included: three randomised controlled trials (RCTs) and two non-RCTs evaluating pharmacological interventions or mechanical devices for middle ear pressure equalisation; and 13 case series and one retrospective controlled before-and-after study evaluating surgical interventions. None was conducted in the UK. All studies were small (11 to 108 participants). Most non-surgical studies reported including mixed populations of adults and children. All except two studies were at high risk of bias, and subject to multiple limitations. Based on a single RCT, nasal steroids showed no improvement in symptoms or middle ear function for patients with otitis media with effusion and/or negative middle ear pressure. Very short-term improvements in middle ear function were observed in patients receiving directly applied topical decongestants or a combination of antihistamine and ephedrine. Single trials found two pressure equalisation devices were each associated with significant short-term improvements in symptoms, middle ear function and/or hearing. Eustachian tuboplasty (seven case series) and balloon dilatation (three case series) were associated with improved outcomes. Positive results were also reported for myringotomy (two case series), directly applied topical steroids (one case series) and laser point coagulation (one controlled before-and-after study). High rates of co-interventions were documented. Minor complications of surgery and pharmacological treatments but no serious adverse effects were reported.
LIMITATIONS
The evidence was limited in quantity and overall was of poor quality. No data were identified on several interventions despite extensive searches.
CONCLUSIONS
It is not possible to draw conclusions regarding the effectiveness of any of the interventions for the treatment of adults with an ETD diagnosis, and there is insufficient evidence to recommend a trial of any particular intervention. Further research is needed to address lack of consensus on several issues, including the definition of ETD in adults, its relation to broader middle ear ventilation problems and clear diagnostic criteria.

: Blue blocking (BB) lenses, including spectacles and intraocular lenses, work by attenuating short-wavelength light. BB glasses are being marketed with the aim to reduce eye fatigue symptoms when using digital devices, improve sleep quality and potentially confer protection from retinal phototoxicity. BB intraocular lenses following cataract surgery may be implanted because they are thought to prevent age-related macular degeneration (AMD) progression.: The present study is a systematic review aiming to analyze BB lenses clinical efficacy in preventing blue light-related ocular disorders, including AMD progression, eye fatigue, and their impact on sleep quality. We searched Medline, PubMed, Web of Science and the Cochrane Library until May 2020.:Although several studies have been performed investigating BB lenses, clinical efficacy for preventing or attenuating the above-mentioned ocular disorders is often theorical or based on laboratory or animal experiments. To date, there is a lack of consistent evidence for a larger-sclale introduction of BB lenses in the routine clinical practice.

Review
INTRODUCTION
Cataract accounts for over 47% of blindness worldwide, causing blindness in about 17.3 million people in 1990. Surgery for cataract in people with glaucoma may affect glaucoma control.
METHODS AND OUTCOMES
We conducted a systematic review and aimed to answer the following clinical questions: What are the effects of surgery for age-related cataract without other ocular comorbidity? What are the effects of treatment for age-related cataract in people with glaucoma? What are the effects of surgical treatments for age-related cataract in people with diabetic retinopathy? What are the effects of surgical treatments for age-related cataract in people with chronic uveitis? We searched: Medline, Embase, The Cochrane Library, and other important databases up to May 2010 (Clinical Evidence reviews are updated periodically; please check our website for the most up-to-date version of this review). We included harms alerts from relevant organisations such as the US Food and Drug Administration (FDA) and the UK Medicines and Healthcare products Regulatory Agency (MHRA).
RESULTS
We found 20 systematic reviews, RCTs, or observational studies that met our inclusion criteria. We performed a GRADE evaluation of the quality of evidence for interventions.
CONCLUSIONS
In this systematic review we present information relating to the effectiveness and safety of the following interventions: for people with cataract without other ocular co-morbidity: cataract surgery alone, cataract surgery with non-concomitant glaucoma surgery, concomitant cataract and glaucoma surgery, intracapsular extraction, manual (large or small) incision extracapsular extraction, and phaco extracapsular extraction; for people with cataract with co-morbid diabetic retinopathy: cataract surgery alone, and adding diabetic retinopathy treatment to cataract surgery; for people with cataract and co-morbid chronic uveitis: cataract surgery, and medical control of uveitis at the time of cataract surgery.
