PURPOSE: To assess whether pars plana vitrectomy (PPV) is an aerosol-generating procedure (AGP) in an ex vivo experimental model. METHODS: In this ex vivo study on 10 porcine eyes, optical particle counter was used to measure particles ≤10 µm using cumulative mode in the six in-built channels: 0.3 µm, 0.5 µm, 1 µm, 2.5 µm, 5 µm and 10 µm aerosols during PPV. Two parts of the study were as follows: (1) to assess the pre-experimental baseline aerosol count in the theatre environment where there are dynamic changes in temperature and humidity and (2) to measure aerosol generation with 23-gauge and 25-gauge set-up. For each porcine eye, five measurements were taken for each consecutive step in the experiment including pre-PPV, during PPV, fluid-air exchange (FAX) and venting using a flute with 23-gauge set-up and a chimney with 25-gauge set-up. Therefore, a total of 200 measurements were recorded. RESULTS: With 23-gauge and 25-gauge PPV, there was no significant difference in aerosol generation in all six channels comparing pre-PPV versus PPV or pre-PPV versus FAX. Venting using flute with 23-gauge PPV showed significant reduction of aerosol ≤1 µm. Air venting using chimney with 25-gauge set-up showed no significant difference in aerosol of ≤1 µm. For cumulative aerosol counts of all particles measuring ≤5 µm, compared with pre-PPV, PPV or FAX, flute venting in 23-gauge set-up showed significant reduction unlike the same comparison for chimney venting in 25-gauge set-up. CONCLUSION: PPV and its associate steps do not generate aerosols ≤10 µm with 23-gauge and 25-gauge set-ups.

Cataract surgery is the most frequently performed elective surgery worldwide. Although considered a safe procedure, potentially sight-threatening adverse events are possible. Among these, post-surgical inflammation and infections are the most relevant. Anti-inflammatory drugs, such as corticosteroids, and topical antibiotics are the pillars for the treatment of inflammation and for the prevention of infections. However, uncertainties remain regarding the duration of both topical antibiotic prophylaxis and corticosteroid treatment. LEADER7, a recent international clinical study conducted with the new fixed combination of levofloxacin and dexamethasone eye drops in patients undergoing uncomplicated cataract surgery, found that 1-week topical antibiotic prophylaxis is just as effective as the 2-week course commonly used in clinical practice. The study also showed that treatment for 1 week with dexamethasone results in complete resolution of inflammatory signs and symptoms in over 85% of patients, for whom further prolongation of corticosteroid treatment is, therefore, not necessary. This new treatment strategy can represent a significant step forward to reduce the unjustified use of prophylactic antibiotics after cataract surgery, limiting the emergence of bacterial resistance, as well as representing an opportunity to optimize the use and safety of the corticosteroid treatment.

PURPOSE: The purpose of this study was to determine the epidemiological, clinical and therapeutic features of ocular foreign bodies in our practice setting. METHODS: We conducted a cross-sectional descriptive study with retrospective data collection at the Sainte Ivonne ophthalmology center in Lubumbashi. We studied 98 medical records of patients seen from January through December 2016 for an ocular foreign body. The parameters used for this study were: age, gender, profession, circumstances of the injury, nature of the foreign body, complications, location, entry site, management and prognosis. RESULTS: The frequency of ocular foreign bodies was 2.4%. We saw predominantly young subjects; the mean age was 33.18±17.98 years. Males predominated, with a frequency of 78.57% of the cases, for a gender ratio of 3.7 men to women. The circumstances of the injuries were primarily work-related (36.46% of cases). The type of foreign body was most commonly wood (41.8% of cases). The FB was corneal in 81.7% of cases, conjunctival (bulbar and tarsal) in 13.3% of cases, and limbal in 5% of cases. Treatment consisted of either simple removal (86.61% of cases) or removal with suturing for deeper foreign bodies (13.27% of cases). The functional results obtained were encouraging; 90.82% of patients recovered well with preservation of visual acuity. The majority of the complications consisted of superficial punctate keratopathy in 27.53% of cases and corneal ulcer in 26.53% of cases. The results of our study are consistent with those in the literature in terms of the frequent corneal location of FB's. CONCLUSION: Ocular foreign bodies represent a situation of non-negligable severity and thus require proper early management in order to prevent progression to visual loss or blindness.

The clinical evaluation of infectious keratitis takes place largely through biomicroscopic examination, which presents limitations in the evaluation of the depth of the infiltrate and the exact thickness of the cornea, whether edematous or thinned. In this study, we aim to quantify the human corneal inflammatory response in treated infectious keratitis by anterior segment optical coherence tomography (AS-OCT). Patients with infectious keratitis were recruited prospectively in the ophthalmology department of the military hospital of Rabat between November 2017 and May 2019. Over the study period, 32 patients were included. A standardized scanning protocol was used. The thickness of the infiltrate, when present, and corneal thickness in any area of thinning and any surrounding edematous areas were measured. The various thicknesses gradually decreased over the course of follow-up, providing objective evidence of therapeutic efficacy in the early stages. Improvement in corneal edema and thinning was faster in the early stage. AS-OCT scanning can be used along with slit lamp examination to quantify and objectively follow infectious keratitis.

Purpose: To analyze the pattern of laboratory investigations of uveitis at a tertiary referral eye care center in Singapore.Methods: Retrospective analysis of 2040 uveitis cases from the Ocular Autoimmune Systemic Inflammatory Infectious Study (OASIS) database over a 12-year period (2004 - 2015).Results: Patients with retinal vasculitis (RV) had the most tests utilized per patient (6.79), followed by intermediate uveitis (IU) (5.25), panuveitis (Pan) (5.12), posterior uveitis (PU) (4.17), anterior uveitis (AU) (2.75), and keratouveitis (KU) (1.10). The most frequently utilized test for infective etiology were the VDRL (41.3%), Syphilis IgG (29.5%), and T-SPOT.TB (24.6%). For autoimmune tests, ANA was most utilized (18.2%), followed by anti-dsDNA (14.8%), and HLA-B27 (12.4%).Conclusion: There was high utilization of autoimmune tests such as ANA, anti-dsDNA, RF, and ANCA, despite its limited yield. Rationalization of investigations in patients with ocular inflammation via a stepladder approach may help optimize the use of limited resources.

RESUMO Objetivo: Avaliar as características das urgências oftalmológicas atendidas no Pronto Socorro do Instituto de Olhos de Goiânia, com destaque à conjuntivite infecciosa, morbidade de maior incidência neste Serviço. Visa ainda delinear as principais etiologias encontradas dentre as conjuntivites infecciosas e compará-las às encontradas em diversos outros serviços de referência em Oftalmologia, norteando, assim, futuros diagnósticos e tratamentos das patologias infecciosas oculares. Métodos: Estudo transversal e retrospectivo, com 783 pacientes atendidos na emergência oftalmológica do Instituto de Olhos de Goiânia, no período de primeiro de maio a 03 de setembro de 2017. Os dados foram coletados por meio de protocolos baseados nos prontuários físicos da emergência oftalmológica do hospital. Resultados: Observou-se que, quanto às causas diagnósticas, a principal foi a conjuntivite aguda, seguida, em ordem decrescente de incidência, por hordéolo e corpo estranho em superfície ocular, com porcentagens, respectivamente, de 10,98% e 9,96%. Dentre os 783 pacientes admitidos na emergência neste período, 302 foram diagnosticados com conjuntivite, representando uma porcentagem de 38,56% da totalidade dos atendimentos. Dentre essas, 226 foram diagnosticados como sendo de etiologia bacteriana e 38 de etiologia viral. Os números absolutos nos levam a uma porcentagem de 74,8% de conjuntivite bacteriana. Conclusão: A conjuntivite infecciosa representa uma porcentagem substancial dentre as patologias admitidas nos serviços de urgência oftalmológica em todo o mundo. No presente estudo houve ainda prevalência da conjuntivite bacteriana, bem como uma tendência irrefutável à instituição precoce de antibioticoterapia tópica. A alta prevalência desta comorbidade e a dificuldade no diagnóstico clínico da etiologia da infecção reitera a necessidade de realização de maiores estudos na área, a fim de otimizar o diagnóstico e a terapêutica da conjuntivite infecciosa.
ABSTRACT Objective: Evaluate the epidemiology of ocular emergencies in a Reference Ophthalmological Hospital in Goiânia, with emphasis on acute infectious conjunctivitis, morbidity with a higher incidence in this Service. It aims to delineate the main etiologies found among infectious conjunctivitis and to compare them with those found in several others Ophthalmology reference services, thus guiding future diagnoses and treatments of ocular infectious diseases. Methods: A cross-sectional and retrospective study was conducted with 783 patients seen at the ophtalmological emergency of the Goiânia Institute of Eyes from May 1 to September 3, 2017. Data were collected through protocols based on physical charts of the ophthalmologic emergency of the hospital. Results: The most common ocular emergencies were acute conjunctivitis, followed in decreasing order of incidence by hordeolum and foreign body on ocular surface, with percentages, respectively, of 10.98% and 9.96%, respectively. Among the 783 patients admitted to the emergency room in this period, 302 were diagnosed with conjunctivitis, representing a percentage of 38.56% of the total number of visits. Of these, 226 were diagnosed as having bacterial etiology (74.8%) and 38 (25.2%) as viral etiology. Conclusion: Infectious conjunctivitis represents a substantial percentage of the pathologies admitted to ophthalmological emergency services worldwide. In the present study there was also a prevalence of bacterial conjunctivitis, as well as an irrefutable tendency to the early institution of topical antibiotic therapy. The high prevalence of this comorbidity and the difficulty in the clinical diagnosis of the etiology of the infection reiterates the need for further studies in the area in order to optimize the diagnosis and treatment of infectious conjunctivitis.

Ophthalmic disease encountered in the intensive care unit (ICU) has a wide spectrum of prevalence and severity. Prolonged exposure of the cornea is common and preventable. Trauma, glaucoma, infection, vascular disease, and burns are among the potential causes of vision loss. Patients are predisposed to ocular complications by the ICU environment and critical illness itself. Critically ill patients require prioritization of life-sustaining interventions, and less emphasis is placed on ophthalmic disease, leading to missed opportunities for vision-saving intervention. It is therefore imperative for intensivists, nurses, and other providers to have an increased awareness and understanding of the broad range of ocular conditions potentially seen in the ICU.

Purpose: To report occurrence of acute severe inflammation after surgical implantation of mycoplasma-infected induced pluripotent stem cell-derived RPE (iPS-RPE) cells into the eyes of healthy primates, and determine the immunopathological mechanisms of the inflammation. Methods: Ophthalmic allogeneic transplantation of iPS-RPE cells was performed in the subretina of major histocompatibility complex (MHC)-matched (two eyes) and MHC-mismatched (one eye) healthy cynomolgus monkeys. The clinical course after transplantation was observed using color fundus photography, fluorescence angiography, and optical coherence tomography. After the animals were killed at 1 month after surgery, eyeballs were removed and pathologically examined. Microorganisms were analyzed by PCR methods and BLAST analysis using preserved graft iPS-RPE cells and the recipients' vitreous humor. Mixed lymphocyte-RPE assay was performed on the mycoplasma-infected and noninfected iPS-RPE cells in vitro. Results: In tested eyes, abnormal findings were observed in the grafted retina 2 weeks after surgery. Here, we observed retinal vasculitis and hemorrhage, retinal detachment, and infiltration of inflammatory cells into the retina of the eyes. One month after surgery, animals were killed due to the severe immune responses observed. Using PCR methods, sequence analysis detected mycoplasma-DNA (Mycoplasma arginini species) in both the grafted RPE cells and the collected vitreous fluids of the monkeys. Mixed lymphocyte-RPE assay revealed that the infected iPS-RPE cells enhanced the proliferation of inflammatory cells in vitro. Conclusions: Transplantation of graft iPS-RPE cells contaminated with mycoplasma into the subretina caused severe ocular inflammation. Mycoplasma possesses the ability to cause immune responses in the host.

PURPOSE: To describe the association of water exposure with contact lens (CL)-related disease and explore the guidelines regarding water exposure to CL wearers, provided by CL manufacturing industry, global public health, and CL-related professional associations. METHODS: A review of the literature was conducted by searching PubMed, MEDLINE, and Web of Science databases up to September 2017 for articles published or translated in English using keywords: contact lens* AND tap water OR swimming OR showering OR water exposure AND microbial keratitis OR Acanthamoeba keratitis OR corneal infiltrate* OR ocular adverse event*. References in all relevant publications were also reviewed. RESULTS: Water exposure during CL wear is associated with complications ranging from sterile corneal infiltrative events to sight-threatening infections. Despite the documented risks due to water exposure, water-related habits are common among CL wearers. This suggests a lack of awareness and understanding regarding the risks among CL wearers and potentially CL practitioners. Discrepancies exist in guidelines for CL hygiene and compliance provided by the CL manufacturing industry, global public health, and CL-related professional associations. There is also widespread use of water imagery within CL marketing and packaging materials. These factors may give rise to confusion among wearers and may contribute toward risk-taking behaviors. CONCLUSIONS: Consensus among stakeholders about water and CL care is needed. Guidelines should unequivocally advocate for the avoidance of any water exposure including handling CLs with wet hands, rinsing CLs or storage cases in tap water, showering while wearing CLs and swimming with CLs without wearing goggles.

A 40-year-old man had uneventful small-incision lenticule extraction. Three days later, the uncorrected distance visual acuity was 20/20 and the cornea was clear without intraocular inflammatory in both eyes. At 6 days, the patient presented with a foreign-body sensation in the right eye but with no decrease in vision. Dense infiltration was visible at the inferior nasal corneal rim on slitlamp microscopy. Anterior segment optical coherence tomography showed the lesion in the junction of the capsular bag and the lenticular edge. Confocal microscopy showed a large number of inflammatory cells and dendritic cells in the infiltration area. After the patient's frequent use of antibiotic and glucocorticoid eyedrops, the inferior corneal infiltration was absorbed and there were significantly fewer inflammatory cells and dendritic cells.

Accidents related to Africanized honey bees are growing globally and are associated with multiple stings owing to the aggressive behavior of this species. The massive inoculation of venom causes skin necrosis and rhabdomyolysis leading to renal failure. Anaphylactic manifestations are more common and are treated using well-defined treatment protocols. However, bee venom-induced toxic reactions may be serious and require a different approach. We report the case of a 3-year-old child, which would help clinicians to focus on the treatment approach required after an incident involving multiple bee stings.

BACKGROUND: Recurrent corneal erosion is a common cause of disabling ocular symptoms and predisposes the cornea to infection. It may follow corneal trauma. Measures to prevent the development of recurrent corneal erosion following corneal trauma have not been firmly established. Once recurrent corneal erosion develops, simple medical therapy (standard treatment) may lead to resolution of the episode. However, some people continue to suffer when such therapy fails and repeated episodes of erosion develop. A number of treatment and prophylactic options are then available but there is no agreement as to the best option. This review version is an update to the original version published in 2007 and a previous update published in 2012. OBJECTIVES: To assess the effectiveness and adverse effects of regimens for the prophylaxis of further recurrent corneal erosion episodes, the treatment of recurrent corneal erosion and prophylaxis of the development of recurrent corneal erosion following trauma. SEARCH METHODS: We searched CENTRAL, which contains the Cochrane Eyes and Vision Trials Register; MEDLINE; Embase; LILACS; the ISRCTN registry; ClinicalTrials.gov and the ICTRP. The date of the search was 14 December 2017. SELECTION CRITERIA: We included randomised and quasi-randomised trials that compared a prophylactic or treatment regimen with another prophylaxis/treatment or no prophylaxis/treatment for people with recurrent corneal erosion. DATA COLLECTION AND ANALYSIS: We used standard methods expected by Cochrane. Two authors independently screened search results, extracted data and assessed risk of bias in the included studies using the Cochrane tool for assessing risk of bias. We considered the following outcome measures: resolution of symptoms after treatment; recurrence after complete or partial resolution; symptoms (pain); adverse effects (corneal haze, astigmatism). We graded the certainty of the evidence using GRADE for the three most clinically relevant comparisons. MAIN RESULTS: We included eight randomised and two quasi-randomised controlled trials in the review, encompassing 505 participants. Seven studies were from Europe (Germany, Sweden and the UK), two from East Asia (Hong Kong and Japan) and one from Australia. Nine of the studies examined treatments for episodes of recurrent corneal erosions and one study considered prophylaxis to prevent development of recurrent corneal erosions after injury. Two of the nine treatment studies also enrolled participants in a study of prophylaxis to prevent further episodes of recurrent corneal erosions. The studies were poorly reported; we judged only one study low risk of bias on all domains.Two studies compared therapeutic contact lens with topical lubrication but one of these studies was published over 30 years ago and used a therapeutic contact lens that is no longer in common use. The more recent study was a two-centre UK study with 29 participants. It provided low-certainty evidence on resolution of symptoms after treatment with similar number of participants in both groups experiencing resolution of symptoms at four months (risk ratio (RR) 0.97, 95% confidence interval (CI) 0.62 to 1.53). There was very low-certainty evidence on recurrence after partial or total resolution at seven months' follow-up (RR 1.07, 95% CI 0.07 to 15.54). There was no evidence of an important difference in pain score (score of 3 in the contact lens group and score of 2 in the topical lubrication group, low-certainty evidence) and no adverse effects were reported. The older study, using a contact lens no longer in common use, found an increased risk of pain and complications with the contact lens compared with hypromellose drops and paraffin ointment at night.A single-centre, Australian study, with 33 participants, provided low-certainty evidence of an increased risk of recurrence with phototherapeutic keratectomy compared with alcohol delamination but with wide confidence intervals, compatible with increased or decreased risk (RR 1.27, 95% CI 0.48 to 3.37). Time to recurrence was similar in both groups (6.5 and 6 months, low-certainty evidence). On average people receiving phototherapeutic keratectomy reported less pain but confidence intervals included no difference or greater pain (mean difference (MD) -0.70, 95% CI -2.23 to 0.83, low-certainty evidence). No adverse effects were reported.A 48-participant study in Hong Kong found recurrences were less common in people given diamond burr superficial keratectomy after epithelial debridement compared with sham diamond burr treatment after epithelial debridement (RR 0.07, 95% CI 0.01 to 0.50, moderate-certainty evidence). The study did not report pain scores but adverse effects such as corneal haze (RR 0.92, 95% CI 0.06 to 13.87, low-certainty evidence) and astigmatism (0.88 versus 0.44 dioptres, moderate-certainty evidence) were similar between the groups.A study comparing transepithelial versus subepithelial excimer laser ablation in 100 people found low-certainty evidence of a small increased risk of recurrence of corneal erosion at one-year follow-up in people given the transepithelial compared with subepithelial technique, however, the confidence intervals were wide and compatible with increased or decreased risk (RR 1.20, 95% CI 0.58 to 2.48, low-certainty evidence). Other outcomes were not reported.Other treatment comparisons included in this review were only addressed by studies published two decades or more ago. The results of these studies were inconclusive: excimer laser ablation (after epithelial debridement) versus no excimer laser ablation (after epithelial debridement), epithelial debridement versus anterior stromal puncture, anterior stromal puncture versus therapeutic contact lens, oral oxytetracycline and topical prednisolone (in addition to 'standard therapy') versus oral oxytetracycline (in addition to 'standard therapy') versus 'standard therapy'. AUTHORS' CONCLUSIONS: Well-designed, masked, randomised controlled trials using standardised methods are needed to establish the benefits of new and existing prophylactic and treatment regimes for recurrent corneal erosion. Studies included in this review have been of insufficient size and quality to provide firm evidence to inform the development of management guidelines. International consensus is also needed to progress research efforts towards evaluation of the major effective treatments for recurrent corneal erosions.

BACKGROUND: Drawing attention to home birth conditions and subsequent neonatal infections is a key starting point to reducing neonatal morbidity which are a main cause of mortality in sub-Saharan Africa. OBJECTIVES: To determine the proportion of respiratory, ophthalmic, and diarrhoeal infections in neonates; the proportion of mothers of neonates, following clean delivery practices; and to explore existing community practices during delivery and the neonatal period. METHODS: A descriptive, cross-sectional, exploratory study, including 10 questionnaires and five Key-Informant interviews, in rural Karamoja, Uganda. RESULTS: Post-delivery razor blade and string use was 90%, but clean delivery surface use only 30%, while 90% obtained bathing water for neonates from boreholes. No mothers washed hands after latrine-related activities compared with 83% for food-related activities. None delivered in health centres or with skilled birth attendants. Respiratory infections occurred in eight neonates, compared to two ophthalmic infections, and no diarrhoea. CONCLUSION: Use of clean delivery surfaces needs to be improved as well as washing after latrine-related activities. Diarrhoea was far less common than expected. Since rural Mother-Infant pairs spend the majority of their post-delivery time around the homestead, hygiene impacts neonatal infections to a large degree, possibly even more so than delivery practices.

Infectious uveitis accounts for majority of the cases of uveitis in developing countries. It also encompasses an array of various microorganisms and their clinical presentations. Some of these infectious uveitic entities are familiar, while others are newly emerging in the global ophthalmic world. Many of these entities are also a major cause of morbidity and mortality, and appropriate, timely management is required to save not the eye, but life of the patient. This review highlights the ocular manifestations of various infectious uveitic entities, relevant to the ophthalmologist.
