| This review aims to caution ophthalmologists about the ocular consequences leading to the diagnosis of hepatitis C virus infection. In addition, in this context, the effects of old and new drugs are discussed in the ophthalmological setting. The importance of early diagnosis and the curative treatment of the disease has been reported in the national and international literature, demonstrating that its progression has important implications for daily clinical and surgical ophthalmological practice. Despite the scarcity of studies on new direct-acting antiviral drugs, fewer side effects of these drugs have been shown when compared with conventional interferon treatment with or without ribavirin. The ophthalmologist's risk of becoming infected, as demonstrated by the presence of the virus in ocular structures, and the possibility of contamination, is also discussed.Keywords: Hepatitis C/ complications; Hepatitis C/drug therapy; Interferon/therapeutic use; Direct-acting antiviral drugs RESUMO | Esta revisão objetiva alertar os oftalmologistas sobre as consequências oculares que levam ao diagnóstico da infecção pelo vírus da Hepatite C. Além disso, neste contexto, os efeitos de drogas antigas e novas são discutidos no cenário oftalmológico. A importância do diagnóstico precoce e do tratamento curativo da doença tem sido relatada na literatura nacional e internacional, demonstrando que sua progressão tem implicações importantes para a prática oftalmológica diária. Apesar da escassez de estudos sobre novos medicamentos antivirais de ação direta, foram demonstrados menos efeitos colaterais desses medicamentos quando comparados ao tratamento convencional com interferon, com ou sem ribavirina associado ou não à rivabirina. O risco do oftalmologista de se infectar, como demonstrado pela presença do vírus nas estruturas oculares, e a possibilidade de contaminação, também é discutido.Descritores: Hepatite C/complicações; Hepatite C/tratamento farmacológico; Interferon/uso terapêutico; Drogas antivirais de ação direta
Background: Studies suggest that the pain response may be evaluated using pupillometry and is influenced by factors such as gender and anxiety. Objectives: The aim of this study was to use pupillometry to observe the effects of gender and anxiety on the pain response. Study Design: A randomized, prospective, clinical and interventional study. Setting: Center for Research on Pain at the Federal University of Maranhão, Brazil. Methods: Ninety-six patients were divided into groups according to their level of anxiety as indicated by the Beck questionnaire. Under photopic conditions and using retinography, these patients underwent pupillometry while a painful pressure stimulus of 1,500 kPa was applied to the middle phalanx of each patient’s right middle finger using a pressure algometer. Results: The pupil diameter increased in response to pain in all study participants, regardless of gender and anxiety level; the average pupil diameter was 3.265 ± 0.028 mm before the painful stimulus and 4.31 ± 0.200 mm for the duration of the stimulus (P = 0.0251). There was no significant difference between the genders in the level of anxiety (P = 0.614). Regardless of gender, individuals with moderate to severe anxiety had higher average pupil diameters than individuals exhibiting mild or no anxiety (P = 0.019). Men had a higher average pupil diameter than women (4.53 ± 0.345 mm and 4.48 ± 0.358 mm, respectively); however, this difference was not statistically significant in the presence of moderate to severe anxiety (P = 0.072). Limitations: The number of men with high anxiety was insufficient to create their own group. Conclusions: The pupil dilation in response to a painful stimulus was similar in both genders. Additionally, regardless of gender, the average pupil diameter was greater in the presence of moderate to severe anxiety. Key words: Pupillometry, pain, gender, anxiety
