ABSTRACT
BACKGROUND: The VASOGRADE is a simple aneurysmal subarachnoid hemorrhage (aSAH) grading scale that combines the modified Fisher scale (mFisher) and the World Federation of Neurological Societies (WFNS) grading system, allowing the stratification of delayed cerebral ischemia (DCI) risk. However, the VASOGRADE accuracy in predicting functional outcomes is still to be determined. METHODS: We retrospectively evaluated a multiethnic cohort of consecutive patients with aSAH admitted to a high-volume center in Brazil from January 2016 to January 2019. Patients were classified according to the severity of the clinical presentation (WFNS), the amount of blood in the initial head computerized tomography (mFisher) scan, and the VASOGRADE (green, yellow, red). The primary outcome was to detect DCI-related cerebral infarction, and the secondary outcome was the functional outcome at hospital discharge according to the modified Rankin scale (mRs). Univariate and multivariate logistic regression models were employed. RESULTS: A total of 212 patients (71.7% female, mean age 52.7 ± 12.8) were included. Sixty-nine patients were classified as VASOGRADE-Green (32.5%), 98 patients as VASOGRADE-Yellow (46.9%), and 45 patients as VASOGRADE-Red (20.6%). DCI-related infarction was present in 39 patients (18.9%). The proportions of patients in the VASOGRADE-Green, VASOGRADE-Yellow, and VASOGRADE-Red categories with DCI-related infarction were 7.7, 61.5, and 30.8%, respectively. After a multivariable analysis including age, sex, aneurysm location, and the VASOGRADE classification as variables, both VASOGRADE-Yellow and VASOGRADE-Red were independently associated with DCI-related infarction (odds ratio [OR] 7.69, 95% confidence interval [CI] 2.13-27.8, and OR 8.07, 95% CI 2.03-32.11, respectively) and unfavorable outcome (OR 4.16, 95% CI 1.33-13.03, and OR 25.57, 95% CI 4.45-147.1, respectively). The VASOGRADE discrimination performance for DCI-related infarction (area under the receiver operating characteristic curve) was 0.67 ± 0.04 (95% CI 0.58-0.75; p = 0.001). VASOGRADE-Red had 97.5% specificity for predicting an unfavorable mRs score at discharge (95% CI 92.8-99.5%). Conversely, VASOGRADE-Green had an excellent specificity for predicting favorable outcome at discharge (mRs score 0-2, 95% CI 82.6-95.5%). CONCLUSIONS: In conclusion, in a multiethnic cohort of patients with aSAH, VASOGRADE-Green predicted the absence of DCI and good clinical outcome at discharge with very high specificity, and patients in this category might be selected for early intensive care unit (ICU) discharge, minimizing costs and medical complications associated with prolonged hospital stay. On the other hand, patients categorized as VASOGRADE-Yellow and VASOGRADE-Red were at the highest risk for DCI. They should, therefore, be selected as a priority for care in high-volume aSAH centers, being aggressively monitored for DCI at the ICU. Such stratification methods are crucial, especially in countries with low financial resources and high health care services demand.

PURPOSE: To present a case of stellate nonhereditary idiopathic foveomacular retinoschisis (SNIFR) resolution associated with vitreomacular adherence (VMA) release and propose a potential contributing association between SNIFR and vitreomacular interactions. OBSERVATIONS: A 67-year-old female patient was diagnosed and followed for SNIFR in OD with spectral-domain optical coherence tomography (SD-OCT) scans at presentation and subsequent visits at 3, 6, 16 and 22 months. VMA and foveomacular retinoschisis remained unchanged on SD-OCT during the first 6 months of the follow-up. At 16-month follow-up visit, SD-OCT revealed VMA release and an important improvement of the macular schisis. At 22 months of follow-up, SNIFR cavities completely resolved in the presence of posterior hyaloid separation from the macular area without any adjunct treatment. The authors could not identify any other possible cause to justify the resolution of SNIFR other than VMA release in this case. Patient did not undergo any treatment for OD other than phacoemulsification 3 months after initial visit. CONCLUSION: The present case illustrates with SD-OCT scans a possible association between SNIFR resolution and VMA release, highlighting a potential tractional component of the posterior vitreous on the internal limiting membrane and consequent glial cells stretching with schisis formation.
ABSTRACT
BACKGROUND: The purpose of the current study is to report the anatomical and functional results of off-label human amniotic membrane graft as primary intervention to repair large to giant macular holes and in reoperations when wide internal limiting membrane peeling was unsuccessful. METHODS: Retrospective chart review was carried out in five different centers to identify all cases that had undergone off-label human amniotic membrane graft for the treatment of large or failed macular holes (MH). Data collected included age, gender, other concomitant diagnosis, symptoms duration, lens status, number of previous surgeries, macular hole measurements (minimum and base linear diameters), mean post-operative follow-up (months), and pre- and post-operative best corrected visual acuity (BCVA). Main outcome measures were anatomical MH closure rates and final BCVA (in logMAR). Nonparametric Wilcoxon rank-sum test was used because the data was not normally distributed, a P values < 0.05 were considered statistically significant. RESULTS: Nineteen eyes of 19 patients were identified and included in the study. Mean age was 66.21 ± 14.96 years and predominantly females (84%). All eyes had successfully closed MH with a single intervention with no recurrences during a mean of 9 ± 3.87 months follow-up. The median BCVA in logMAR preoperative was 1.30 ± 0.44 (0.80-2.0), approximately 20/400 on Snellen chart and the median BCVA in logMAR postoperative was 1.0 ± 0.72 (0.4-3.0) approximately 20/200 (p < 0.0001) with median of three lines of visual improvement. CONCLUSION: The use of human amniotic membrane graft seems to be a viable and effective alternative for the treatment of large and persistent macular holes. However, further larger prospective controlled studies are necessary to confirm our preliminary results of this new surgical technique.

Motor neuron disease is one of the major groups of neurodegenerative diseases, mainly represented by amyotrophic lateral sclerosis. Despite wide genetic and biochemical data regarding its pathophysiological mechanisms, motor neuron disease develops under a complex network of mechanisms not restricted to the unique functions of the alpha motor neurons but which actually involve diverse functions of glial cell interaction. This review aims to expose some of the leading roles of glial cells in the physiological mechanisms of neuron-glial cell interactions and the mechanisms related to motor neuron survival linked to glial cell functions.

ABSTRACT Purpose: To evaluate if Eyesi cataract surgical simulator training using its standard course curriculum is effective in improving performance of cataract surgery trainees on creating capsulorhexis on high-tension capsules on the simulator. Methods: We retrospectively analyzed training reports of ophthalmic surgery trainees (2nd and 3rd year residents and cataract fellowship trainees) that have accomplished the standard Eyesi cataract surgery simulator training course version 2.1 between May 2012 and August 2013 at Instituto de Diagnostico e Terapia Ocular, Rio de Janeiro, Brazil. We compared the mean score (from 0 to 100) attributed by the simulator on performing the same task, a capsulorhexis on a high-tension capsule, on the surgical simulator "before training" (during beginning of the course) and "after training" (at later stages of the course). Results: Thirty-seven trainees' reports were analyzed. Mean and standard deviation "before training" high-tension capsulorhexis score was 41.73 ± 27.08 points and the mean "after training" score was 72.55 ± 16.40 points, a difference of +30.82 points (p value <0.001 on Paired t test), representing a 73% improvement on performance. Conclusions: Eyesi surgical simulator training on course version 2.1 curriculum was effective in improving performance of cataract surgery trainees on creating capsulorhexis on high-tension capsules.
RESUMO Objetivos: Avaliar se o treinamento realizado com o simulador cirúrgico de catarata Eyesi e o seu currículo de exercícios padrão são efetivos em melhorar o desempenho de cirurgiões de catarata em formação na confecção de capsulorrexe em cápsulas de alta tensão realizadas no simulador. Métodos: Analisamos retrospectivamente relatórios de treinamento de residentes de 2º e 3º ano e fellows de catarata que realizaram o curso versão 2.1 de treinamento com o simulador cirúrgico de catarata Eyesi no período de maio de 2012 a agosto de 2013 no Instituto de Diagnóstico e Terapia Ocular, Rio de Janeiro, Brasil. Comparamos o escore médio (de 0 a 100 pontos) atribuído na confecção de capsulorrexe em cápsula de alta tensão no simulador "antes do treinamento" (durante início do curso) e "depois do treinamento" (nos estágios finais do curso). Resultados: Trinta e sete relatórios de cirurgiões em treinamento foram analisados. O escore médio e desvio padrão da capsulorrexe em cápsula de alta tensão "antes do treinamento" foi de 41,73 ± 27,08 pontos e "depois do treinamento" de 72,55 ± 16,40 pontos, uma diferença de +30,82 pontos (p <0.001 no teste t pareado), representando uma melhora de 73% no desempenho. Conclusão: O treinamento realizado com o simulador cirúrgico de catarata Eyesi seguindo o currículo do curso versão 2.1 foi eficaz em melhorar o desempenho de cirurgiões em treinamento na confecção de capsulorrexe em cápsulas de alta tensão.

BACKGROUND: To perform a microbiological contamination analysis of the vitreous during office-based micro-incision vitrectomy surgery (MIVS) assessing whether the bacteria detected correlated with patient's ocular conjunctival flora. METHODS: This is a prospective, interventional, nonrandomized case series of patients undergoing office-based MIVS, anti-VEGF, and dexamethasone intravitreal injections (triple therapy) for the treatment of wet age-related macular degeneration (AMD) and diabetic macular edema (DME).All patients were operated at a small procedure room in an ambulatory clinic of the Department of Ophthalmology, University of Montreal, Quebec, Canada. Conjunctival samples were done before placing the sclerotomies. The MIVS was done with a 23-gauge retractable vitrector, a 27-gauge infusion line, and a 29-gauge chandelier. Undiluted and diluted vitreous were collected for aerobic, anaerobic and fungal cultures. Outcomes measured were bacterial species identification within samples collected from the conjunctiva and the vitreous. RESULTS: Thirty-seven patients (37 eyes) were recruited and completed over 17 months of follow-up. Twenty-eight had wet AMD and nine had DME. There were 13 men and 24 women, with a mean age of 78 years. Eighteen patients (46%) had culture positive conjunctival flora. Twenty-six bacterial colonies were tabulated in total from the conjunctival swabs. All bacteria detected were gram-positive bacteria (100%), most commonly: Staphylococcus epidermitis in 11 (42%) and Corynebacterium sp. in 6 (23%). Only 1/18 patients had more than 3 species isolated, 6/18 patients had 2 species and 11/18 patients had 1 species identified on the conjunctival swab. Only 1 of the 37 undiluted midvitreous samples was culture positive, equating to a contamination rate of 2.7%. None of the diluted vitreous samples were culture positive. All cultures were negative for fungus. No serious postoperative complications occurred, including bacterial endophthalmitis, choroidal detachment, and retinal detachment. CONCLUSION: This preliminary study of office-based MIVS gives us insights on the ocular surface microbial profile and vitreous contamination rate of performing such procedures outside the OR-controlled environment. Our initial results seem to indicate that there is little risk of bacterial translocation and contamination from the conjunctiva into the vitreous. Therefore, if endophthalmitis occurs post-operatively, the source may likely arise after the procedure. Larger studies are needed to confirm our data.

Purpose. To investigate the in vivo incision architecture using spectral domain optical coherence tomography (SD-OCT) in 23-gauge and 25-gauge transconjunctival sutureless pars plana vitrectomy (TSPPV). Methods. A prospective observational study of 22 eyes of 22 patients that underwent three-port 25-gauge (10 eyes) or 23-gauge (12 eyes) TSPPV was performed. The three sclerotomies sites in each eye were analyzed by Corneal Adapter Model (CAM) RTVue SD-OCT (Optovue Inc., Fremont, CA, USA) with wound cross-section images (longitudinal and transversal) on days 1, 7, and 30 postoperatively. Transversal and longitudinal length, location, angle between the conjunctival surface tangent and the incision plane, and architecture deformations were evaluated. Results. All patients (22 eyes) completed the study and surgeries lasted less than 60 minutes. All wounds were obliquely performed, 23-gauge mean angle was 23 ± 5°, and 25-gauge angule was 21 ± 4°. Twenty-three-gauge sclerotomy transversal mean length was 1122 ± 242 µ m and 25-gauge transversal sclerotomy mean length was 977 ± 174 µ m; 23-gauge longitudinal mean length was 363 ± 42 µ m and 25-gauge longitudinal sclerotomy mean length was 234 ±19 µ m; 23-gauge open wound thickness mean was 61 ± 28 µ m and 25-gauge open wound thickness mean was 22 ± 6 µ m. All results were statistically significant (P < 0.05). No vitreous incarceration or silicone oil residue was observed in incision sites with both gauges. Conclusions. The 23-gauge and 25-gauge architectural wound constructions were well visualized using CAM SD-OCT. Statistical differences between the two gauges were observed throughout the study period.
ABSTRACT
PURPOSE: To describe a novel surgical technique for drainage of bullous serous and hemorrhagic choroidal detachments. METHODS: A prospective, consecutive case series of 6 eyes with serous and/or hemorrhagic choroidal detachments secondary to intraocular surgery was documented to evaluate the feasibility of using the 25-gauge and 20-gauge transconjunctival trocar/cannula systems to drain choroidal detachments. Two eyes had expulsive hemorrhagic choroidal detachments and 4 eyes had serous choroidal detachments after glaucoma surgeries. A 25-gauge infusion line was placed in the anterior chamber. A 20-gauge (in eyes with hemorrhagic choroidal detachments) or a 25-gauge (in eyes with serous detachments) trocar/cannula system was inserted into the suprachoroidal space 7.0 mm from limbus. After drainage, the cannulas were removed and no sutures were placed. Pars plana vitrectomy was performed only in eyes with concomitant pathology that demanded the additional procedure. The primary outcome measure was presence of choroidal detachment at 1 week, 2 weeks, and 1 month postoperatively. Secondary outcome measures were visual acuity at 6 months and intraocular pressure at 1 week and 1, 3, and 6 months postoperatively. RESULTS: Drainage of hemorrhagic choroidal detachments resulted in resolution of the detachments by 1 month postoperatively. In eyes with serous detachments, resolution was achieved by 1 week postdrainage. In both groups, intraocular pressure increased to at least 10 mmHg by postoperative Week 1. The visual acuity improved in all eyes. No complications related to the transconjunctival technique were noted. CONCLUSION: Transconjunctival drainage of serous and hemorrhagic choroidal detachments seems to be a feasible and simple surgical option with minimal scleral and conjunctival damage. Pars plana vitrectomy may not be necessary when draining choroidal detachments in this manner.

ABSTRACT
Objetivos: Comparar a influência do descolamento posterior do vítreo parcial com o total nos resultados cirúrgicos de olhos fácicos submetidos à cirurgia para correção de descolamento regmatogênico da retina com retinopexia pneumática, retinopexia e introflexão escleral ou vitrectomia via pars plana. Pacientes e Métodos: Foi realizado um estudo prospectivo mascarado observacional de uma série consecutiva de setenta e cinco olhos fácicos com descolamento regmatogênico da retina e rotura em "ferradura". Estes olhos foram avaliados por meio de exame oftalmológico, incluindo ultrassonografia B dinâmica para a análise pré-operatória da interface vítreo -retiniana posterior. A decisão sobre a técnica cirúrgica foi tomada sem o conhecimento dos resultados da ultra sonografia, sendo que olhos sem vitreorretinopatia proliferativa foram submetidos à retinopexia pneumática, retinopexia e introflexão escleral ou vitrectomia via pars plana e os olhos com vitreorretinopatia proliferativa foram submetidos à vitrectomia via pars plana. Os pacientes foram divididos em dois grupos conforme o resultado da ultra-sonografia pré-operatória: descolamento posterior do vítreo parcial e total. Foram analisados e comparados entre os grupos o sucesso anatômico primário e final, o índice de reoperações e a acuidade visual final corrigida. Resultados: Dos setenta e quatro pacientes (75 olhos) recrutados para o estudo, 61 (62 olhos - 81,3 por cento) completaram 12 meses de acompanhamento pós-operatório. Dezoito olhos foram submetidos à retinopexia pneumática (9 com descolamento posterior do vítreo parcial e 9 com total), 15 à retinopexia e introflexão escleral (8 com descolamento posterior do vítreo parcial e 7 com total) e 17 à vitrectomia via pars plana com e sem introflexão escleral associada(5 com descolamento posterior do vítreo parcial e 12 com total) (au)

Objetivo: Descrever a técnica de bloqueio retrobulbar com apenas 2ml de xilocaína 2 por cento para a cirurgia de facoemulsificação desenvolvida por nosso anestesista e os seus resultados em uma série de pacientes. Casuísticas e Métodos: Foram selecionados 19 pacientes, com riscos cirúrgicos ASA I e II, que seriam submetidos a cirurgia de catarata por facoemulsificação através de incisão córnea clara. O bloqueio retrobulbar foi realizado por nosso anestesista em todos os pacientes. A anestesia foi realizada através de punção no terço externo da pálpebra inferior com agulha biselada 30x7mm atingindo o espaço retrobulbar (cone muscular), injetando-se 2ml de xilocaína 2 por cento sem vaso constritor e posterior compressão com balão de Honan. Foi realizada a avaliação da acuidade visual com a tabela de Snellen de 10 em 10 minutos após a cirurgia de catarata para avaliar em que momento o bloqueio perdia o efeito sobre a visão. Resultados: Foram analisados 19 pacientes, sendo 12 mulheres e 11 olhos direitos. A idade média dos pacientes foi de 71,2 anos. Todos os pacientes tinham o globo ocular paralisado no per-operatório e o movimento palpebral de abrir e fechar após a cirurgia. A duração do efeito anestésico sobre a visão foi em média de 82,1 minutos. Considerou-se o término do efeito anestésico sobre a visão o momento em que o paciente retornava a acuidade visual, que em média foi fr 0,35 (variando de 0,1 a 0,4) sem correção. A acuidade visual final com correção, avaliado um mês após a cirurgia, foi em média de 0,9. Conclusão: Concluímos que o bloqueio retrobulbar com apenas 2ml de xilocaína 2 por cento permite uma boa acinesia do globo ocular no per-operatório sem que se percam os movimentos palpebrais após a cirurgia de facoemulsificação. A vantagem desse método é a rápida recuperação visual e a não oclusão ocular após a cirurgia.
