Uso de drogas antiglaucomatosas em pacientes com glaucoma severo: quantas são necessarias para controle da doenca? / Use of antiglaucomatous drugs in patients with severe glaucoma: how many are necessary to control the disease?

Resumo Introdução: O glaucoma e a principal causa de cegueira irreversivel no Brasil. Ate o momento nao se dispoe de uma droga ideal para o controle da pressao intraocular (PIO), geralmente necessitando associar dois ou mais medicamentos hipotensores, com frequentes instilacoes diarias e ma aderencia ao tratamento. Objetivos: Descrever quantitativa e qualitativamente as drogas usadas para controle da PIO e a eficacia do tratamento na prevencao da cegueira. Métodos: Estudo transversal retrospectivo, atraves de revisao de 420 prontuarios de portadores de Glaucoma severo acompanhados no ambulatorio do Hospital Emilio Carlos, de Catanduva-SP, de janeiro/2014 a dezembro/2016. As variaveis analisadas foram: idade, acuidade visual e medicamentos antiglaucomatosos utilizados: topicos (colirios) e sistemicos. Resultados: A media de idade dos participantes foi 62,99±16,29 anos. Foram detectados 68 casos de cegueira, sendo que 3 pacientes (0,7%)perderam a visao no tempo investigado, com referencias a periodos sem tratamento/subdose/instilacao indevida/uso de 3 ou 4 colirios. Em 73,3% dos casos conseguiu-se estabilizacao da PIO com o uso de um (38,1%) ou no maximo 02 (35,2%) colirios associados. Houve correlacao significativa entre o no de combinacoes de hipotensores topicos e o no de pacientes em uso de Acetazolamida. O medicamentomais usado foi o Maleato de Timolol (67,1%). Conclusões: Na maioria dos pacientes a PIO foi controlada com 1 ou 2 colirios associados; pequena porcentagem dos casos evoluiu para cegueira; muito provavelmente a evolucao para perda de visao foi decorrente da complexidade e ma aderencia ao tratamento.

ABSTRACT Introduction: Glaucoma is the main cause of irreversible blindness in Brazil. To date, there is no ideal drug for the control of intraocular pressure (IOP), usually requiring the combination of two or more hypotensive drugs, with frequent daily instillations and poor adherence to treatment. Objectives: To describe quantitatively and qualitatively the drugs used to control IOP and the efficacy of treatment in the prevention of blindness. Methods: A retrospective cross-sectional study was carried out through a review of 420 medical records of patients with severe Glaucoma who were followed up at the Emílio Carlos Hospital outpatient clinic in Catanduva, SP, from January 2014 to December 2016. The analyzed variables were: age, visual acuity and antiglaucomatous drugs used: topical (eye drops) and systemic. Results:The mean age of participants was 62.99 ± 16.29 years. Sixty-eight cases of blindness were detected, and three patients (0.7%) lost vision at the time investigated, with references to periods without treatment / subdose / improper instillation / use of 3 or 4 eye drops. In 73.3% of the cases, IOP stabilization was achieved with one (38.1%) or at most 02 (35.2%) associated drops. There was a significant correlation between the number of combinations of topical hypotensive agents and the number of patients taking acetazolamide. The drugmostused was Timolol (67.1%). Conclusions: In the majority of patients IOP was controlled with 1 or 2 associated eye drops; small percentage of cases evolved into blindness; most likely the evolution to loss of vision was due to the complexity and poor adherence to the treatment.

Ocular surface evaluation in patients treated with a fixed combination of prostaglandin analogues with 0.5% timolol maleate topical monotherapy: a randomized clinical trial

OBJECTIVES: To compare ocular surface changes induced via glaucoma treatment in patients using fixed combinations of prostaglandin analogues (travoprost, latanoprost and bimatoprost) with 0.5% timolol maleate METHODS: A prospective, multicenter, randomized, parallel group, single-blind clinical trial was performed in 33 patients with ocular hypertension or open angle glaucoma who had not been previously treated. The ocular surface was evaluated prior to and three months after treatment, with a daily drop instillation of one of the three medications. The main outcome measurements included the tear film break-up time, Schirmer's test, Lissamine green staining, the Ocular Surface Disease Index questionnaire, impression cytology using HE and PAS and immunocytochemistry for interleukin-6 and HLA-DR. Ensaiosclinicos.gov.br: UTN - U1111-1129-2872 RESULTS: All of the drugs induced a significant reduction in intraocular pressure. Decreases in the Schirmer's test results were observed with all of the drugs. Decreases in tear-film break-up time were noted with travoprost/timolol and latanoprost/timolol. An increase in the Lissamine green score was noted with travoprost/timolol and bimatoprost/timolol. The Ocular Surface Disease Index score increased after treatment in the travoprost/timolol group. Impression cytology revealed a significant difference in cell-to-cell contact in the same group, an increase in cellularity in all of the groups and an increase in the number of goblet cells in all of the groups. The fixed combinations induced an increase in IL-6 expression in the travoprost/timolol group, in which there was also an increase in HLA-DR expression. CONCLUSIONS: All of the fixed combinations induced a significant reduction in intraocular pressure, and the travoprost/timolol group showed increased expression of the inflammatory markers HLA-DR and interleukin-6. All three tested medications resulted in some degree of deterioration in ...

The prevalence of ocular surface complaints in Brazilian patients with glaucoma or ocular hypertension / Prevalência de sintomas da doença da superfície ocular em pacientes brasileiros com glaucoma ou hipertensão ocular

PURPOSE: To examine the prevalence of ocular surface complaints in Brazilian patients with glaucoma or ocular hypertension who used topical intraocular pressure (IOP)-lowering regimens. METHODS: In this multicenter, noninterventional, single-visit study, adults with glaucoma or ocular hypertension treated with an IOP-lowering regimen were administered the 12-item ocular surface disease index (OSDI) questionnaire. Each response was scored on a 5-point scale, with 0 indicating symptom present none of the time and 4 indicating symptom present all of the time. The average of the 12 item responses for each patient was transformed to a scale from 0 to 100, with higher scores representing worse disabilities. OSDI results then were categorized as absence of OSD (scores of 0-12), mild OSD (scores of 13-22), moderate OSD (scores of 23-32), or severe OSD (scores of 33100). RESULTS: The 173 enrolled patients had a mean age of 61.2 years, were women in 65.3% of cases, and had glaucoma in 89.0% of cases and ocular hypertension in 11.0% of cases. OSDI scores for 158 patients using 1 IOP-lowering therapy indicated no OSD in 37.3% of patients (59/158), mild OSD in 20.9% (33/158), moderate OSD in 17.1% (27/158), and severe OSD in 24.7% (39/158). For the 120 patients using 1 IOP-lowering medication and having a known duration of diagnosis of glaucoma or ocular hypertension, mean OSDI scores were numerically higher (worse) for the 39 patients with a diagnosis ≥6 years long (score 25 [± 20], indicating moderate OSD) than for the 81 patients with a diagnosis lasting <6 years (score 22 [± 20], indicating mild OSD); however, no significant differences in OSDI scores by duration of diagnosis were evident in means (P=0.49), distributions (P≥0.26), or correlation (P=0.77). CONCLUSIONS: A large proportion of Brazilian patients treated with 1 IOP-lowering therapy had some ocular surface complaints.

OBJETIVO: Avaliar a prevalência de sintomas decorrentes de doença de superfície ocular (DSO) em pacientes brasileiros com glaucoma ou hipertensão ocular que utilizam tratamento ocular tópico para redução da pressão intraocular (PIO). MÉTODO: Neste estudo multicêntrico, não intervencional de uma única visita, pacientes adultos com glaucoma ou hipertensão ocular em tratamento para redução da pressão intraocular (PIO) responderam aos 12 itens do questionário "índice de doença da superfície ocular" (OSDI). Cada resposta foi pontuada numa escala de 5 pontos, com 0 (zero) indicando a ausência de sintomas e 4 indicando sintomas presentes todo o tempo. A média de respostas dos 12 itens para cada paciente foi transformada numa escala de 0 a 100, com pontuações mais elevadas representando piores deficiências. Os resultados do OSDI foram categorizados como ausência de DSO (pontuação de 0-12), DSO leve (pontuação de 13-22), DSO moderada (pontuação de 23-32) ou DSO grave (pontuação de 33-100). RESULTADOS: Os 173 pacientes incluídos apresentavam idade média de 61,2 anos, 65,3% eram mulheres (65,3%), tinham glaucoma em 89,0% dos casos e hipertensão ocular em 11,0% dos casos. As pontuações do OSDI para os 158 pacientes utilizando uma medicação para redução da PIO indicaram "DSO ausente" em 37,3% dos pacientes (59/158), "DSO leve" em 20,9% (33/158), "DSO moderada" em 17,1% (27/158) e "DSO grave" em 24,7% (39/158). Para os 120 pacientes utilizando medicação redutora da PIO e com duração conhecida do diagnóstico de glaucoma ou hipertensão ocular, a pontuação média do OSDI foi numericamente superior (pior) para 39 pacientes com diagnóstico realizado há mais de 6 anos (pontuação 25 [± 20] indicando DSO moderado) do que para 81 pacientes com o diagnóstico realizado há menos de 6 anos (pontuação 22 [± 20] indicando DSO leve); no entanto, não houve diferença estatisticamente significativa na média da pontuação OSDI na duração do diagnóstico (P=0.49), distribuição (P≥0,26), ou correlação (P=0,77). CONCLUSÃO: Uma grande proporção de pacientes brasileiros tratados com uma medicação para redução da PIO apresenta sintomas decorrentes de doença da superfície ocular (DSO).
