RESUMO Objetivo: Avaliar o filme lacrimal e os sintomas de olho seco antes e após a realização da facoemulsificação. Métodos: Participaram deste estudo clínico 51 pacientes diagnosticados com catarata (55% mulheres; 78% brancos; 71,2 ± 6,5 anos de idade; sem uso de colírio lubrificante) que foram submetidos à facoemulsificação em um hospital na cidade de Aparecida (SP). A análise do filme lacrimal foi feita pelo teste de ruptura do filme lacrimal, e os sintomas de olho seco foram avaliados pelo Índice de Doença da Superfície Ocular, ambos antes da cirurgia e 30 e 60 dias de pós-operatório. Resultados: Na análise pré-operatória, 25,5% dos pacientes tinham olho seco pelo critério subjetivo (Índice de Doença da Superfície Ocular ≥ 25%), enquanto a proporção de pacientes com olho seco foi de 92,2% pelo critério objetivo (teste de ruptura do filme lacrimal < 10 segundos). Não houve correlação entre o teste de ruptura do filme lacrimal e o Índice de Doença da Superfície Ocular (r = −0,14; p = 0,33). Não foi observada redução dos sintomas de olho seco (15,9 ± 17,6 versus 12,2 ± 13,2 versus 7,8 ± 11,5; p < 0,001) e nem do tempo de ruptura do filme lacrimal (6,2 ± 2,2 vs. 4,3 ± 2,0 versus 6,9 ± 2,0 segundos; p < 0,001) no pré, 30 e 60 dias após a cirurgia. Conclusão: A facoemulsificação desencadeia sintomas de olho seco e altera os valores do teste de ruptura do filme lacrimal e do Índice de Doença da Superfície Ocular, havendo melhora depois da cirurgia, com o passar dos dias. Observou-se que, após os 60 dias, os sintomas de olho seco avaliados pelo Índice de Doença da Superfície Ocular apresentaram melhora. Em relação ao filme lacrimal, avaliado pelo teste de ruptura do filme lacrimal, observou-se que houve piora estatisticamente significativa aos 30 dias, seguida de melhora no pós-operatório de 60 dias. Os resultados sugerem que a análise clínica do olho seco deve ser realizada por diferentes métodos, preferencialmente objetivos.

Dry Eye Disease (DED) is a pathology that can be caused by genetic and environmental factors. It is characterized by the loss of homeostasis of the tear film, triggering symptoms such as pain, burning, redness, blurred vision, tearing, and photophobia. It is emphasized that the treatments are aimed at restoring the ocular surface and reducing tear film instability. Hyaluronic acid (HA) has emerged as a promising treatment for this disease. The aim of this study was to seek rationale for this condition and to evaluate the efficacy of the use of HA in its treatment. The methodology used was a literature search based on the descriptor: "{(Hyaluronic Acid)} AND {(Dry Eye)}" in the PubMed and Science Direct databases. Of the 4652 articles selected, 38 that related DED and HA. In this perspective, there are several mechanisms that are part of the pathophysiology of DED, which run with the loss of tear film homeostasis. Thus, HA, with its various applicability, has become a therapeutic option due to its different modes of application and its very few side effects. However, the importance of the development of an updated protocol and the continuity of studies on this condition is still emphasized. [ABSTRACT FROM AUTHOR]

Objective: to evaluate the clinical predictors for dry eye and the nursing diagnosis Risk of dry eye in postoperative patients in the Post-Anesthesia Care Unit. Method: cross-sectional study conducted between May and August, 2017. The sample was 157 adult patients undergoing elective surgical procedures. Data were analyzed using descriptive and inferential statistics. Results: the clinical diagnosis of dry eye prevailed in 85.35% of patients, and the nursing diagnosis Risk of dry eye in 14.65%. Statistical differences were observed between hyperemia, excessive tearing and insufficient Schirmer test with the diagnosis of ocular dryness in the right eye and with the diagnosis Risk of dry eye. In the left eye the Schirmer test was insufficient. Conclusion: hyperemia, excessive tearing and insufficient Schirmer test are relevant perioperative clinical predictors to promote preventive measures and/or early detection of dry eye.

Objective: To describe the use of subconjuctival administration of the anti-tumor necrosis factor agent adalimumab for treatment of dry eye in patients with Sjögren's syndrome, and to investigate conjunctival healing. Methods: Prospective, nonrandomized, noncomparative interventional case series including consecutive patients with Sjögren's syndrome and dry eye disease treated with subconjunctival adalimumab, who were refractory to conventional treatment. Patients with infectious ocular surface involvement or structural changes in the tear pathway or eyelids were excluded. Data recorded included age, sex, lissamine green staining pattern, Schirmer test results, intraocular pressure, conjunctival mobility, tear break up time and findings of biomicroscopic evaluation, following fluorescein dye instillation. The Ocular Surface Disease Index questionnaire validated for the Portuguese language was used for subjective assessment of patients. Results: Eleven eyes of eight patients were studied. Mean patient age was 53±13.4 years. Patients were treated with subconjunctival injection of 0.03 mL of adalimumab and followed for 90 days thereafter. There were no statistically significant objective improvement (objective tests results; p>0.05) and no statistically significant changes in intraocular pressure (p=0.11). Questionnaire responses revealed a significant improvement in ocular symptoms (p=0.002). Conclusion: Based on the Ocular Surface Disease Index questionnaire, subconjunctival administration of adalimumab improved dry eye symptoms. However, objective assessments failed to reveal statistically significant improvements. [ABSTRACT FROM AUTHOR]

Objective: To compare the clinical efficacy of two different doses of topical cyclosporine A used in addition to artificial tears in the treatment of patients with meibomian dysfunction and secondary dry eye. Methods: Fifty patients aged 18 to 40 years, who presented to our clinic between June 2020 and June 2021 were included in our study. Patients were divided into two groups as Group A (topical cyclosporine A 0.05%) and Group B (topical cyclosporine A 0.1%). All the patients underwent a detailed ophthalmological examination, basal Ocular Surface Disease Index measurement, and Schirmer 1 and tear break-up time tests at all visits. Results: The mean age was 32±7.1 years in Group A and 30.7±8.5 years in Group B. In Group A, there were 15 women and ten men, and Group B consisted of 14 women and 11 men. There was no difference between the groups in terms of age and gender distribution (p>0.05). Schirmer 1 and tear break-up time results and Ocular Surface Disease Index score also did not significantly differ between the groups (p>0.05). Conclusion: Cyclosporine A 0.05% and 0.1% eye drops were both seen to be effective in managing dry eye disease in patients with meibomian gland dysfunction. [ABSTRACT FROM AUTHOR]

Objetivo: Identificar na literatura publicações sobre os fatores de risco para o olho seco em pacientes internados em unidade de terapia intensiva de adultos. Método: Realizou-se busca nas bases de dados MedLine, CINAHL, Web of Knowledge, LILACS, Cochrane, IBECS e BDENF. Foram identificadas 620 publicações potencialmente elegíveis para inclusão nesta revisão, selecionando-se ao final vinte e sete publicações que atenderam aos critérios de inclusão. Essas foram analisadas por dois pesquisadores independentes, usando-se instrumento adaptado para verificar o nível de evidência. Resultado: Foram identificados 39 diferentes fatores de risco para olho seco, sendo que os apontados em 50% ou mais dos estudos, o lagoftalmo (85,18%), uso de sedativos (70,37%), ventilação mecânica (66.66%) e uso de bloqueadores musculares (55,55%). Conclusão: Foi encontrado somente um estudo que abordasse especificamente o problema do olho seco em pacientes críticos; estudos clínicos são necessários, a fim de se apresentar evidências científicas fortes ao problema.

Objective: To evaluate the long-term efficacy of autologous platelet -rich plasma (PRP) in the symptomatic dry eye of diabetic patients after 6 months of treatment suspension. Methods: A single intervention group, prospective study, series of cases; ten diabetic patients with refractory dry eye disease who used PRP and were reassessed 6 months after discontinuation of treatment. At the initial stage 221 diabetic patients were evaluated for dry eye, of these 12 were submitted to CPC, and evaluated for symptoms, Ocular Surface Disease Index (OSDI), TFBUT (Tear Film Break Up Time) and Schirmer's Test. At this stage of the study, patients were recruited after 6 months of CCP suspension, and the OSDI, TFBUT and Schirmer test scores were reviewed. Results: There was a statistically significant difference in the OSDI and TFBUT scores between the baseline (before PRP treatment) and after 1 month of PRP use; between the baseline and after 6 months of PRP use, and between the values after 1 month of use and after 6 months of non-use (p = 0.005, p = 0.010 and p = 0.028, p = 0.04, p = 0 , 03 and p = 0.02, respectively). Schirmer test values had no significant difference in any of the comparisons (p = 0.09, p = 0.26, p = 0.47 respectively). Conclusions: PRP after 6 months of use presents evidence that it would still be effective even with suspension of eye drops. [ABSTRACT FROM AUTHOR]

Graft-versus-host Disease (GVHD) is a major complication with high morbidity and mortality rates on patients undergoing hematopoietic stem cell transplantation. The ocular involvement, named ocular GVHD, may affect all structures of the eyes, but the lacrimal unit (lacrimal glands and ocular surface) is the main target of the inflammatory response mediated by the donor T cells. The development of dry eye disease is the main clinical ocular manifestation, and the association of a variety of therapeutics options is necessary. The aim of the review is to describe the clinical manifestations, diagnostic criteria, impact in quality of life, the current treatment and future perspectives of this disease that demands a multidisciplinary follow-up.

The aim of this review is to list the ophthalmological conditions in which platelet concentrate (CP) has been used, as well as its biochemical and physiological properties. The CP has both anticatabolic potential, present in autologous serum, and substances with anabolic properties, which together are responsible for its benefits in the treatment of ocular surface diseases. There is currently a shortage of clinical trials in this area, both in ophthalmology and other medical areas, with more studies and reports on the use of autologous serum. In ophthalmology, CP has been used in the treatment of symptomatic dry eye, corneal ulcers and ocular burns, among other applications, being an effective alternative in several ocular pathologies; therefore, it’s evident the importance of more studies in this topic to prove the efficiency of this product.

Objective: To identify the effect of polyethylene film on the prevention of dry eye in critically ill patients admitted to an adult intensive care unit. Methodology: A systematic review study, guided by PRISMA recommendations. Seven databases were searched through strategies that involved the cross-referencing of Dry Eye Syndromes, Keratoconjunctivitis Sicca, Corneal Diseases, Risk Factors, Intensive Care Units, Hospital and Nursing. Results: A total of 784 primary studies were identified, 35 were evaluated and four were selected, with reference to the use of polyethylene film for the prevention of dry eye. There was a slight superiority in the effectiveness of the polyethylene film in relation to the other interventions. Conclusion: The evidence was not sufficient to establish whether the efficacy of the polyethylene film is superior to that of other interventions. We suggest performing a randomized clinical trial to verify the efficiency of different nursing interventions in the prevention of dry eye in critically ill patients. [ABSTRACT FROM AUTHOR]

OBJETIVO: Verificar a prevalência de disfunção lacrimal em grávidas, comparando-a com a de mulheres não grávidas. Correlacionar achados de diminuição do filme lacrimal com antecedentes obstétricos. MÉTODOS: Foram entrevistadas 150 mulheres grávidas e 150 não grávidas para avaliação da presença de sintomas de secura ocular e antecedentes obstétricos. Os dois grupos foram submetidos ao teste de Schirmer I e a um questionário para sintomas de olho seco. Pacientes com colagenoses, uso de medicamentos associados à secura de mucosas, hepatite C e infecção por vírus da imunodeficiência humana, inflamação intraocular prévia ou cirurgia ocular foram excluídas. Os dados obtidos foram analisados por testes de Χ2 e Fisher quanto às variáveis nominais, e pelo t de Student e Mann-Whitney quando numéricos. A significância adotada foi de 5%. RESULTADOS: Os dois grupos não diferiram quanto aos sintomas relacionados à secura ocular. O valor absoluto do teste de Schirmer foi igual nos dois grupos, tanto para olho direito (p=0,3) como esquerdo (p=0,3). Todavia, as mulheres grávidas tiveram maior prevalência de disfunção lacrimal em pelo menos um olho (p=0,004). A ocorrência de disfunção lacrimal nos dois grupos (pacientes e controles) estava associada a maior número de gestações a termo por paciente (p=0,04), mas não com número de abortos (p=0,9), nem com o tempo da gravidez (p=0,5). CONCLUSÕES: Mulheres grávidas têm mais disfunção lacrimal do que não grávidas. Nos dois grupos a prevalência de disfunção lacrimal é mais alta em mulheres com maior paridade.PURPOSE: To assess the prevalence of lacrimal dysfunction during pregnancy comparing it to non-pregnant women and to correlate these findings with obstetric history. METHODS: We interviewed 150 pregnant and 150 non-pregnant women for symptoms of dry eyes and obstetric history. Both groups underwent Schirmer I testing and responded to a questionnaire on dry eye symptoms. Patients with collagen diseases, medications associated with dryness of mucous membranes, hepatitis C infection and AIDS, previous intraocular inflammation and eye surgery were excluded. Data were analyzed by the Χ2 and Fisher tests when the data were nominal and by the Student´s t-test and Mann-Whitney test when numerical. The level of significance was set at 5%. RESULTS: The two groups did not differ in symptoms of lacrimal dysfunction. The results of Schirmer's test were equal in both groups for the right eye (p=0.3) and left eye (p=0.3). However, pregnant women had a higher prevalence of at least one dry eye (p=0.004). The occurrence of dry eye in both groups (patients and controls) was associated with a greater number of full-term pregnancies/patient (p=0.04) but not with pregnancy time (p=0.5) or number of abortions (p=0.9). CONCLUSIONS: Pregnant women suffer more from lacrimal dysfunction than non pregnant women; in both groups the prevalence of tear dysfunction is more elevated in women with higher parity.

OBJETIVO:Avaliar a presença da síndrome da disfunção lacrimal e alterações na sensibilidade corneana no pré e pós-operatório de pacientes com indicação de blefaroplastia superior. MÉTODOS: Foram avaliados 30 pacientes com indicação cirúrgica para correção de dermatocálase em pálpebra superior de ambos os olhos. Obtida história clínica e realizado exame oftalmológico geral, incluindo exames como teste de Schirmer I, coloração com Lissamina Verde, tempo de ruptura do filme lacrimal, coloração com fluoresceína e teste da sensibilidade corneana com estesiômetro de Cochet-Bonnet, além de teste subjetivo pelo questionário ODSI. Os exames foram realizados antes e após 90 dias da cirurgia. RESULTADOS: Apenas 23 pacientes completaram o seguimento, sendo o sexo feminino predominante. A idade dos pacientes variou de 63 a 87 anos. De acordo com o questionário ODSI aplicado, observou-se que houve melhora dos sintomas, mas a análise estatística mostrou um resultado não-significante. Com relação à análise dos resultados obtidos com o estesiômetro de Cochet-Bonnet, 7 pacientes apresentaram uma melhora na sensibilidade corneana, 9 pacientes diminuíram a resposta e 7 mantiveram seus valores. Os resultados do BUT lacrimal, colorações com Lissamina verde e Fluoresceína foram considerados estatisticamente não-significantes. O teste de Schirmer I demonstrou uma melhora estatisticamente significativa da produção lacrimal no pós-operatório. CONCLUSÃO: Neste trabalho observou-se que os pacientes submetidos à blefaroplastia superior apresentaram uma melhora nos sinais e sintomas relacionados à SDL, apesar de ter sido diagnosticado uma diminuição na sensibilidade corneana não estatisticamente significante.

Objective: To investigate the correlation between phenol red test and Schirmer tear test on tear quantification together with a questionnaire to detect symptoms of dry eye. Methods: A total of 49 patients were enrolled at this study. Each participant had its eyes examined by the two tests. The dry eye symptoms were evaluated by a total of 5 questions. The data were collected and analysed by Kappa statistical method to check the concordance between the tests. Results: A sum of 65.3% of the patients referred dry eye symptoms. When grouping them by age, 70.5% of the patients older than 60 years had symptoms, while in the group of 40-59 years, 59.3% reported symptoms. Schimer tear test was positive for dry eye in 51%(25) of the patients, against 65.3%(32) in the phenol red test. Kappa value between the tests were 0.548, which indicates a moderate agreement of the them. Conclusion: The symptomatic questionnaire showed a higher frequency of dry eye in the elderly. Kappa value displayed an moderate agreement, which is relevant, specially because neither of the tests are the gold standard for the diagnosis of dry eye, and for the variability of results that testing can bring.
