RESUMO
Many studies have evaluated different treatments for ischemic central retinal vein occlusion (CRVO). Nevertheless, improvement and complication rates vary significantly. This systematic review aimed to evaluate the efficacy of laser therapy in treating ischemic CRVO compared with a control group using other treatments. The databases of PubMed, Google Scholar, and ClinicalTrials.gov were searched using a variety of keywords, including "ischemic central retinal vein occlusion," "CRVO," "laser," and "panretinal photocoagulation." After data extraction, each study's quality was assessed using the methodological index for nonrandomized studies (MINORS) or grading of recommendations, assessment, development, and evaluation or GRADE standards. A sum of 195 abstracts were reviewed, and seven clinical trials were eventually chosen. Of these, four were prospective studies, two were randomized controlled studies, and only one was a retrospective study. The assessment of potential biases in our included studies revealed that all these studies demonstrated moderate or high quality. Two studies were selected for meta-analysis, and the results showed no significant difference in visual acuity (VA) outcomes between the treated and the control groups (P = 0.17). In the remaining five studies, laser therapy was found to be more effective at neovascular complications, with a higher rate of neovascular glaucoma (NVG), iris neovascularization (NVI), neovascularisation at disc (NVD), and retinal neovascularization in the group without laser treatments. This review suggests that laser therapy is essential in preventing neovascular complications, such as NVG, NVI, NVD, and retinal neovascularization rather than improving VA. In addition, the combination of laser photocoagulation and intravitreal injection (IVI) improved VA, but further studies are required.
RESUMO
Central serous chorioretinopathy (CSCR) is an idiopathic chorioretinal disease characterized by localized serous detachment of the neurosensory retina at the macula. To date, there is no high-quality evidence of recent updates on treating acute CSCR, focusing on photodynamic therapy (PDT) and anti-vascular endothelial growth factor (anti-VEGF). Hence, this review aims to conduct a comprehensive systematic review of the most recent therapeutic approaches for acute CSCR using the following electronic databases for a comprehensive and systematic literature review: MEDLINE, EMBASE, and Cochrane. In addition, we analyzed studies comparing PDT with placebo, anti-VEGF with placebo, or PDT with anti-VEGF in treating acute CSC eyes with no previous intervention. Seven studies were included, with a total of 292 eyes. The overall positive results were significantly higher among patients who received PDT compared to control groups (odds ratio [OR] = 7.96, 95% confidence interval [CI], 3.02 to 20.95, p < 0.001). The proportions of positive results were 81.0% and 97.1% among patients who received anti-VEGF and PDT, respectively, with no statistically significant differences between the groups. In addition, there were no significant differences between anti-VEGF and control groups. In contrast, PDT was significantly associated with lower recurrence odds than the control groups (OR = 0.12, 95% CI, 0.04 to 0.39, p = 0.042). According to our findings, PDT showed higher positive results than anti-VEGF in acute CSCR. In addition, PDT was significantly associated with a lower recurrence rate than the control group. However, the analysis needs to be confirmed and updated by large-scale, well-designed randomized clinical trials.
RESUMO
Post-keratoplasty (KP) patients' visual acuity can be severely limited by ametropia. Irregular astigmatisms are frequently encountered in these patients and is commonly associated with high degrees of hyperopia or myopia. This systematic review investigates the safety and efficacy of laser refractive surgery for post KP vision correction. 31 studies with 683 participants (732 eyes) enrolled in this review. Mean astigmatism improved significantly (mean difference [MD] = -2.70, 95% CI, -3.13 to -2.28, P < .0001). As well as Mean spherical equivalent (MD = -3.35, 95% CI, -3.92 to -2.78, P < .0001). From 586 participants 5.8% lost 2 or more lines of corrected distance visual acuity after treatment. The proportion of eyes with 20/40 uncorrected distance visual acuity or better was reported and the percentage was 46.79% overall. Laser refractive procedures (laser in situ keratomileusis [LASIK] or photorefractive keratectomy [PRK] or transepithelial PRK) on eyes with corneal transplantation were found to be relatively safe and effective. Our systematic review shows there is improvement in all outcomes. Main adverse effects were haze for PRK and epithelial ingrowth for LASIK.

Purpose: To report a 56-year-old male in Saudi Arabia who developed signs of aberrant facial nerve regeneration after recovering from Bell's palsy associated with COVID-19 infection. Observations: The patient presented, months following recovery from Bell's palsy associated with COVID-19, with symptoms of aberrant seventh nerve regeneration in the form of tearing with eating "crocodile tears" and synchronous right eyelid closure with the jaw movement. Conclusions and Importance: Case reports of Bell's palsy associated with COVID-19 are emerging, but association does not mean causation. That said, we need to report these cases to draw attention to the possible neuroinvasive propensity of this virus. It is also imperative to recognize Bell's palsy as a possible symptom of COVID-19.
RESUMO
INTRODUCTION: With the recent increase in interest in using autologous fat (AF) filler injections to enhance aesthetic facial appearance, there is a noticeable increase in the complications such as vascular compromise and blindness. This systematic review and meta-analysis aimed to understand the symptomatology of ophthalmic complications related to AF facial injections for cosmetic purposes, their underlying causes, management options, and the final clinical outcomes. METHODS: This review was conducted according to the International Prospective Register of Systematic Reviews (PROSPERO) guidelines. In November 2021, we performed a systematic review of available literature using the following electronic databases: Cochrane, MEDLINE, and EMBASE. Our search was limited to the published studies between 2000 and 2021. RESULTS: A total of 1052 publications and 34 articles published were included. Twenty case reports, two case series, one prospective cohort study, and eleven retrospective studies were evaluated. The forehead was the most common single injection site (n = 196, 55.36%). The most common initial symptom was periorbital swelling (92.7%). The pooled prevalence of ophthalmic artery occlusion was 50.4% out of all AF injection-related complications. Regarding the management, most patients were managed conservatively (n = 278, 51.38%). Complete improvement was observed among 423 patients (80.57%). CONCLUSION: Autologous facial fat injection is a minimally invasive procedure with a favorable safety profile in cosmetic applications. However, the common use of these injections in aesthetic surgery has resulted in a concomitant increase in devastating consequences, such as blindness. Therefore, a firm understanding of the potential complications of such interventions is essential. LEVEL OF EVIDENCE III: This journal requires that authors assign a level of evidence to each article.

BACKGROUND: With the global rise in the use of hyaluronic acid (HA) fillers as a minimally invasive cosmetic procedure, significant adverse effects such as vascular compromise and blindness have become common. Hence, we present the first systematic review aimed to investigate ocular complications secondary to a facial HA injection and to understand the presentation, cause, management, and outcome of these complications. METHODS: The preferred reporting items for systematic reviews and meta-analyses (PRISMA) guidelines were used to report this review. A systematic search was performed in July 2021 for published literature using the PubMed, MEDLINE, and Cochrane databases. The following terms were used: facial fillers, facial injections, hyaluronic acid, blindness, ophthalmoplegia, diplopia, ptosis, ophthalmic artery occlusion, posterior ciliary artery occlusion, and ocular ischemic syndrome. RESULTS: A total of 2496 publications were searched, and 34 articles published between January 2000 and July 2021 were included. Twenty-seven case reports and seven case series were evaluated. The nose was the most common site of injection (n = 25; 40.67%). Ocular pain was the most common initial symptom of ocular complications (n = 13, 22.41 %). The most common complication was vision loss (n = 17, 50%). The majority of patients received hyaluronidase, aspirin, and steroids. Regarding the outcome, 15 (45.45%) of the published studies showed no improvement in complications even after management. CONCLUSION: HA is gaining popularity in cosmetic applications. Post-HA ocular complications nearly always have an immediate onset. Proper knowledge of potential adverse events is crucial for clinicians to attempt to decrease complications and improve outcomes. LEVEL OF EVIDENCE III: This journal requires that authors assign a level of evidence to each article.

OBJECTIVES: To determine the prevalence of positive screening of body dysmorphic disorder (BDD) among patients seeking cosmetic surgeries in plastic surgery and oculoplastic surgery clinics. METHODS: The survey of this cross-sectional study was self-administrated and distributed among adults pursuing cosmetic surgeries in plastic surgery and oculoplastic surgery clinics at King Abdulaziz University Hospital, Jeddah, Saudi Arabia, between March 2019 and March 2020. The BDD questionnaire was validated, and a highly sensitive and specific tool was used to identify patients with BDD. Ethical approval was granted by the Research Ethics Committee. All analytic studies were performed using IBM SPSS, version 24. Results: A total of 344 patients participated in this study with a mean age of 39.66 ± 13.76 years. Of these, 296 (86%) were women and 298 (86.6%) were Saudi. The prevalence of positive screening for BDD was 19.2%. The most commonly requested procedures were abdominoplasty (21.2%) and skin lesion removal (21.2%). Smoking was found to be significantly associated with BDD with 21.2% of smokers having it (p less than 0.010). CONCLUSION: Body dysmorphic disorder was unrecognized among patients pursuing cosmetic surgeries. One-fifth of patients requesting cosmetic procedures are potential cases of BDD requiring psychiatric evaluation and treatment. We recommend implementing screening protocols to identify cases before surgical plans.

OBJECTIVE: Although the eyes occupy 0.1% of the total body surface, eye injuries are serious because vision is arguably the most important sense. We aimed to assess knowledge of Saudi Arabian residents regarding steps to be taken in cases of chemical eye injury, in order to promote awareness of such procedures. RESULTS: A cross-sectional design was done. A random sampling method was utilized to select 888 individuals in the Saudi community. Participants completed an electronic closed ended, validated, anonymous, self-administered questionnaire. Two experts assessed content and face validity. Respondents were 18-29 years of age. 74 (8.3%) had a history of chemical eye injury. Regarding the first step taken in case of chemical eye injury, 697 (78.5%) respondents indicated washing with water, 164 (18.5%) indicated visiting the emergency department, 11 (1.2%) indicated using eye drops, and 5 (0.6%) indicated covering the eye immediately. Seventy-five (8.4%) respondents agreed that an eye injured with an acidic material should be washed with an alkaline solution. These results should be confirmed by health authorities and appropriate interventions should be developed for improving knowledge among masses, thereby promoting a healthier society.

RESUMO
BACKGROUND: Although plastic surgery has been gaining a lot of popularity recently, there seems to be limited perception and a poor understanding of this field by both medical professionals, including medical students, and the general public. This might alter referral patterns as well as medical students' choice to pursue a career in plastic surgery. OBJECTIVE: The purpose of this study was to assess knowledge and perception of plastic surgery among medical students and to explore the influencing factors underlying particular beliefs. METHODS: Data for this cross-sectional study were collected between August 22 and December 22, 2017. The questionnaire was formulated on the basis of our own study objectives and from available questionnaires with similar objectives. It was composed of 14 questions divided into three main parts: demographics, the specialty of plastic surgery, and media involvement and its effect on plastic surgery. The study was conducted via an online questionnaire among medical students in all years at King Abdulaziz University Hospital, Jeddah, Saudi Arabia. Data were considered significant at P<.05. All analyses were performed using SPSS, version 20. RESULTS: A total of 886 medical students participated in this study. We achieved a response rate of 56.79%. The mean age of the participants was 21.2 years. The mean awareness score was 9.7 (SD 4.2) for female students and 8.3 (SD 4.2) for male students (P<.001). The condition most commonly known to be treated by a plastic surgeon was burns (70.3% of responses). CONCLUSIONS: Medical students do not have adequate awareness of plastic surgery, and early exposure to this specialty may enhance their awareness.
RESUMO
OBJECTIVES: To determine the prevalence, reasons of use, reported hygienic practices, and complications related to CLs' usage, and to assess awareness of medical students about CLs' hygienic behaviours, King Abdulaziz University (KAU), Jeddah, Saudi Arabia. METHODS: A cross-sectional design was done. A multi-stage stratified random sampling was utilized to select 536 medical students. A validated, self-administered, anonymous questionnaire was used. Both descriptive and inferential statistics were applied. RESULTS: The prevalence of current users of CLs was 40.5%. Females reported significantly much higher prevalence of usage compared to males (OR=8.38; 95% CI:5.2-13.3). Second-year students, and those living in university dormitory had the highest prevalence of CLs usage compared to others. The commonest reason for wearing CLs was cosmetic purpose. Improper CLs-hygienic practices were reported; as exceeding the period required for renewal (45.6%), sharing lenses (16.6%), and sleeping (29.9%), swimming (24.6%) or showering (29.0%) with CLs. Only 16.6% of the participants cleaned their lenses daily. At least one CLs' related complications was reported by 30.4% of the users. Acute red eye (19.8%), conjunctivitis (18.9%), and corneal abrasion (8.3%) were the commonest CLs' complications. CONCLUSION: A relatively high prevalence of CLs' usage was found. Participants were aware about CLs-hygienic practices. However, unhygienic CLs-related practices and complications were also reported. Provision of educational messages and training on sound CLs' hygienic practices are needed.
