RESUMO

ABSTRACT Purpose: To evaluate the efficacy of oral pilocarpine (20 mg daily) for the treatment of dry eye in patients with Sjogren's Syndrome. The frequency of side effects reported during the treatment was also investigated. Methods: In this placebo-controlled crossover study, 32 patients with Sjögren's syndrome were enrolled to receive either oral pilocarpine or placebo for 10 weeks. Following a 2-week washout period, the treatment was inverted for each patient for the same duration. Assessments included the quality of life National Eye Institute Visual Function Questionnaire-25 (NEI-VFQ-25), dry eye specific questionnaire Ocular Surface Disease Index, non-invasive breakup time, invasive breakup time with fluorescein, corneal and conjunctival staining patterns with the use of fluorescein and rose bengal staining, Schirmer's test, and tear ferning test. Results: According to the NEI-VFQ-25, there was statistically significant improvement in the quality of life following oral pilocarpine. Similar results were observed for ocular discomfort, as determined by the Ocular Surface Disease Index. All clinical tests showed favorable and statistically significant results following the use of oral pilocarpine. Regarding the analysis of tear samples, there was an improvement in the quality of tear film. This was evidenced by the modification of the patterns observed in the tear ferning test. Side effects were reported by 96.8% and 56.2% of the patients who received pilocarpine and placebo, respectively. Sweating was the most frequently reported side effect (67.74% versus 11.11%, respectively). Conclusions: Although the treatment was associated with a high frequency of side effects, oral pilocarpine (20 mg daily) was able to relieve discomfort related to dry eyes in patients with Sjögren's syndrome and induce favorable structural changes in the tear film.

RESUMO Objetivos: Avaliar o alívio de sintomas e sinais relacionados à secura ocular e na qualidade de vida de pacientes com síndrome de Sjögren tratados com o uso oral de pilocarpina na dose diária de 20mg. A frequência dos efeitos colaterais relatados com o tratamento também foi estudada. Métodos: Trata-se de estudo cruzado e placebo-controlado, que envolveu 32 pacientes com síndrome de Sjögren em uso de pilocarpina oral ou placebo, por dez semanas. Após duas semanas sem medicações, houve a inversão dos tratamentos para cada paciente, por mais dez semanas. As avaliações foram feitas por meio do questionário de qualidade de vida NEI-VFQ-25, questionário olho seco específico Ocular Surface Disease Index, tempo de ruptura do filme lacrimal não invasivo, tempo de ruptura do filme lacrimal com fluoresceína, avaliação da superfície ocular com os corantes fluoresceína e rosa Bengala, teste de Schirmer e teste de cristalização do filme lacrimal. Resultados: Houve melhora estatisticamente significante na qualidade de vida medida pelo questionário NEI-VFQ-25 e no desconforto ocular avaliado pelo Ocular Surface Disease Index, após o tratamento. Todos os testes clínicos sofreram influência favorável e estatisticamente significante durante a fase de tratamento com pilocarpina oral. Em relação à análise de amostras de lágrimas, ocorreram alterações estruturais indicando melhora no padrão de cristalização do filme lacrimal. Os efeitos colaterais com o uso de pilocarpina foram relatados por 96,8% dos pacientes com a pilocarpina e 56,2% com placebo. Sudorese foi o efeito colateral mais frequentemente relatado (pilocarpina = 67,74%; placebo = 11,11%). Conclusões: O uso oral de pilocarpina na dose diária de 20mg foi capaz de aliviar as queixas de desconforto relacionadas ao ressecamento ocular em pacientes com síndrome de Sjögren, produzir impacto positivo na qualidade de vida dos pacientes e induzir mudanças estruturais favoráveis no filme lacrimal, embora os efeitos colaterais relatados tenham ocorrido com alta frequência.

RESUMO

PURPOSE: Report a new technique for improvement of pterygium surgery: donor graft harvesting with air. CASE REPORTS: We describe a technique that was used with 138 patients who underwent surgery that included a conjunctival autograft and fibrin glue with air injection to dissect the Tenon capsule from the conjunctiva. RESULTS: No complications occurred with this technique and all patients achieved good results. DISCUSSION: The surgical time with this new technique was similar to that reported in the literature. In addition, the graft thickness was close to that reported with femtosecond laser dissection and it was thinner than that reported with aesthetic/saline dissection (unable to determine statistical significance). CONCLUSIONS AND IMPORTANCE: With the injection of an air bubble, we could easily dissect the conjunctiva from the Tenon capsule and quickly acquire thin grafts without any additional costs or complications.

RESUMO

We report the case of a patient who received conjunctival tattooing for cosmetic purposes with associated complications. A 28-year-old male experienced severe ocular pain after undergoing conjunctival tattooing. Slit-lamp examination revealed blue deposits over the conjunctiva in association with intense conjunctival edema and a 4+ anterior chamber cellular reaction. The patient underwent clinical treatments to control ocular inflammation. Two months after the injury, the patient was still in follow-up to ensure that any further complications were managed and documented. This unusual case of conjunctival tattooing resulted in conjunctival edema and anterior uveitis. Because of the increasing popularity of eyeball tattooing, the potentially severe complications of this procedure may become more common.

RESUMO Relatamos um caso de um paciente que realizou tatuagem conjuntival para fins cosméticos com complicações associadas. Um homem de 28 anos de idade apresentou dor ocular importante após tatuagem conjuntival. O exame da lâmpada de fenda revelou depósitos azuis sobre a conjuntiva, associados a um intenso edema conjuntival e uma reação de câmara anterior de 4+ de células. O paciente foi submetido a tratamentos clínicos para controlar a inflamação ocular. Dois meses após o ocorrido, o paciente ainda estava em acompanhamento para garantir que quaisquer outras complicações fossem gerenciadas e documentadas. Um caso incomum de tatuagem conjuntival resultou em edema conjuntival e uveíte anterior. Devido à crescente popularidade da tatuagem no globo ocular, complicações potencialmente graves deste procedimento podem se tornar mais comuns.

RESUMO

PURPOSE:: To identify and evaluate changes in the ocular surface in obese patients with bariatric surgery. METHODS:: The study included 89 randomly selected patients; 81 (91.0%) were women, 35 were preoperative, 32 were included 0-12 months after surgery, and 22 were included >12 months after surgery. All patients completed a dry eye-specific questionnaire and were evaluated by the tear ferning test, tear-film breakup time (BUT), Schirmer's test I, examination of the ocular surface by 1% rose Bengal staining, and impression cytology. Patients were questioned about compliance with nutritional supplementation. RESULTS:: The pre- and postoperative groups did not differ significantly in age (p=0.082), but did differ in body mass index (p<0.001). All test values are within the normal range and there was no statistically significant difference in ocular surface disease index score between the preoperative and postoperative periods. The mean tear-film BUT was lower than that considered normal (10 s) at each time it was tested. No statistically significant group differences were observed in Schirmer's test, BUT, rose Bengal staining, or impression cytology. A high rate of noncompliance with nutritional supplementation was observed. CONCLUSIONS:: No symptoms of xerophthalmia developed in this series of bariatric surgery patients. No changes were observed in any of the specific tests used to evaluate the ocular surface up to 5 years after surgery compared with presurgery results.

RESUMO Objetivos: Analisar os resultados dos testes de avialiação da superfície ocular em pacientes com obesidade submetidos à cirurgia bariátrica e identificar a presença e intensidades das alterações oculares após cirurgia bariátrica. Métodos: O estudo foi composto de 89 pacientes, amostra randômica, sendo 81 mulheres (91,0%). Os pacientes foram agrupados com relação à relação da cirurgia bariátrica: pré-operatório (35 pacientes), pós-operatório 0 a 12 meses (32 pacientes) e mais de 12 meses (22 pacientes). Todos os pacientes foram submetidos a seguinte sequencia de exames: questionário olho seco específico, teste de cristalização do filme lacrimal, teste da tempo de ruptura do filme lacrimal, Schirmer teste I, avaliação da superfície ocular usando rosa bengala, citologia de impressão. Os pacientes foram questionados quanto ao uso da suplementação nutricional. Resultados: Não houve diferença estatística entre os grupos quanto à idade (p=0,082). BMI foi significativamente diferente entre os grupos (p<0,001). Quanto ao OSDI, os valores foram normais, sem diferença estatística entre os períodos pré-operatório e pós-operatório. A média do tempo de ruptura do filme lacrimal foi abaixo do considerado normal (10 segundos) em todos os momentos avaliados. Não houve di ferença estatisticamente significante entre os grupos com relação aos exames: teste de Schirmer, BUT, biomicroscopia com rosa bengala 1% e citologia de impressão. Elevada taxa de uso incorreto da suplementação nutricional foi encontrada (73%). Conclusão: Não houve surgimento de sintomas de xeroftalmia nos pacientes submetidos à cirurgia bariátrica e não foram encontrados alterações em nenhum teste utilizado para avaliar a superfície ocular em cinco anos após a cirurgia em comparação com os pacientes antes da cirurgia.

RESUMO

PURPOSE: To report a case of conjunctival tattooing for cosmetic purposes with inadvertent globe penetration resulting in severe inflammation, capsular lens opacity, and secondary glaucoma. METHODS: Case report. RESULTS: A 25-year-old woman experienced severe ocular pain and decreased vision in the left eye after conjunctival tattooing for cosmetic purposes on the previous day. Slit-lamp examination revealed black deposits over the conjunctiva, corneal endothelium, anterior chamber angle, iris, and anterior capsular lens due to the tattooing pigment. In addition, severe anterior uveitis triggered by the pigments and, later, secondary glaucoma were diagnosed. The patient underwent clinical and surgical treatments to control ocular inflammation and intraocular pressure. Three months after the injury, the patient was still under follow-up treatment in an effort to control the complications of the eyeball tattooing. CONCLUSIONS: An unusual case of conjunctival tattooing resulted in severe inflammation, capsular lens opacity, and secondary glaucoma. Because of the increasing popularity of eyeball tattooing, coupled with the procedure being performed by untrained professionals, potentially severe complications of this procedure may become more common.

RESUMO

PURPOSE: Surface tumors of the eye comprise an ample spectrum of diseases with various clinical manifestations. Diagnosis has been traditionally achieved through core biopsies, but cytology is an innovative, fast, and minimally invasive method. The objective of this study was to investigate the use of exfoliative cytology as an alternative method for the detection of ocular surface squamous neoplasm (OSSN). METHODS: Exfoliative cytology of the lesions was performed by collecting smears using plastic brushes followed by smearing the cells onto slides and subsequently fixing them in 90% alcohol. Incisional biopsies were performed at the exact same location and sent for processing in 10% formaldehyde. Both the surgical pathologist and cytopathologist were masked to the clinical characteristics and to the corresponding cytological or histological result. RESULTS: Twenty-two patients were enrolled in the study (12 men and 10 women, median age 52.5 years). Final histological diagnoses comprised 7 cases of pterygium, 7 squamous-cell carcinomas, 4 squamous papillomas, and 4 chronic inflammatory processes. Cytohistological agreement was achieved in 19 (86.4%) of the samples. Cytology showed a sensitivity, specificity, positive predictive value, and negative predictive value of 85.7%, 86.7%, 75%, and 92.9%, respectively, in detecting OSSN. CONCLUSIONS: Exfoliative cytology of the conjunctival lesions is a simple procedure, with high agreement to the histological follow-up. Its broad use could augment the early diagnosis of OSSN, with improvement in patient prognosis.
