Resumo Objetivos: Avaliar o grau de contaminação por fungos e bactérias e o modo de conservação destes colírios hipotensores por parte dos pacientes no ambulatório de Glaucoma da Santa Casa de Ribeirão Preto. Métodos: Foram selecionados aleatoriamente cinquenta e cinco pacientes, em seguimento no ambulatório, e após consentimento dos mesmos os colírios eram coletados e enviados via correio para análise por microbiologista e patologista em até 72 horas. Foi analisado 0,5ml aproximadamente das medicações e os pacientes respondiam a um questionário simples sobre o método de conservação e se consideravam estes adequados. Resultados: Dos 55 colírios analisados, cinco (9,01%) estavam com seu conteúdo líquido contaminado. Entre os microrganismos isolados haviam 4 bactérias Gram negativas, sendo 1 (1,8%) por Serratia marcescens, 1 (1,8%) Pseudomonas aeruginosa e 2 (3,6%) Stenotrophomas maltophilia. Um colírio estava contaminado pelo fungo Cândida ssp Todos pacientes do estudo julgam seus métodos de armazenamento e instilação adequados. Os pacientes que tiveram os colírios positivados eram convocados para exame clínico e passavam por novo questionário pelo investigador. Conclusão: O tempo de abertura dos frascos e os métodos de conservação influenciam na contaminação dos medicamentos, todos os colírios com crescimento de microrganismos no presente estudo estavam abertos entre 30 e 90 dias. O fato de que a maioria dos pacientes levam seus colírios em tarefas cotidianas, aumenta a exposição dos frascos e podem ser um fator relevante para determinar a contaminação destas medicações.


Abstract Objetives: To assess the degree of fungal and bacterial contamination of hypotensive eye drops and the way these are preserved by the patients at the Glaucoma outpatient clinic of Santa Casa Hospital in Ribeirão Preto. Methods: Fifty-five patients were randomly assigned to follow-up in the outpatient clinic and, after their consent, an eye drop was collected per patient and later sent by mail for analysis by microbiologist and pathologist in up to 72 hours. Approximately 0.5ml of the medications were analyzed and the patients were asked to answer a simple questionnaire on the method of drug conservation and whether they considered it adequate. Results: Of the 55 analysed eye drops, five (9.01%) had their liquid contents contaminated. Among the microorganisms isolated there were 4 Gram negative bacteria, 1 (1.8%) by Serratia marcenses, 1 (1.8%) Pseudomonas aeruginosa and 2 (3.6%) Stenotrophomas maltophilia. An eye drop was contaminated by the fungus Candida ssp. All the patients in the study judged their methods of storage and instillation appropriate. The patients who had the positive coliria were summoned for clinical examination and passed through a new questionnaire by the investigator. Conclusion: The time and methods of preservation influence the contamination of medicinal products. All the eye drops that presented growth of microorganisms in the present study were open between 30 and 90 days. The fact that most patients take their eye drops on daily tasks increases the exposure of the bottles and can be a relevant fact to determine the contamination of these medications.
