ABSTRACT

RESUMO O glaucoma é considerado a maior causa de cegueira irreversível no mundo, e o aumento da pressão intraocular constitui seu principal fator de risco. Usualmente, a terapia inicial do glaucoma consiste na redução da pressão intraocular a partir da instilação de drogas hipotensoras tópicas, estando as cirurgias antiglaucomatosas reservadas, na maioria das vezes, para casos em que o controle da doença não é atingido clinicamente. Classicamente, o tratamento cirúrgico do glaucoma é realizado a partir dos procedimentos filtrantes: trabeculectomia e implante de dispositivos de drenagem. O acrônimo MIGS (do inglês minimally invasive glaucoma surgery, procedimentos minimamente invasivos para glaucoma) corresponde a um grupo de procedimentos cirúrgicos pouco invasivos, que propõem a redução pressórica de maneira mais segura e previsível, quando comparada às técnicas cirúrgicas antiglaucomatosas convencionais.


ABSTRACT Glaucoma is considered the biggest cause of irreversible blindness in the world and the increase in intraocular pressure is its main risk factor. Usually, the initial therapy for glaucoma consists of reducing IOP through the instillation of topical hypotensive drugs, with antiglaucoma surgeries being normally reserved for cases in which disease control is not clinically achieved. Classically, the surgical treatment of glaucoma is performed using filtering procedures: trabeculectomy; non-penetrating sclerotomy and glaucoma drainage devices. The acronym MIGS (Minimally Invasive Glaucoma Surgery) corresponds to a group of minimally invasive surgical procedures that provide a safer and more predictable pressure reduction when compared to conventional antiglaucoma surgical techniques.

ABSTRACT

ABSTRACT Minimally invasive glaucoma surgeries are surgical treatment alternatives for glaucoma aimed at reducing intraocular pressure with a better safety profile compared to traditional trabeculectomy. However, in spite of less invasive techniques, complications may develop in any surgical procedure. To the best of our knowledge, this is the first case report of anterior uveitis following combined treatment with cataract surgery and iStent inject® which addresses the management of postoperative inflammation.


RESUMO As cirurgias minimamente invasivas para glaucoma consistem em uma opção de tratamento cirúrgico para glaucoma, a qual promove redução da pressão intraocular com melhor perfil de segurança do que a trabeculectomia. Todavia, complicações são inerentes à realização de procedimentos cirúrgicos, apesar do uso de técnicas menos invasivas. Este é o primeiro relato que apresenta um caso de uveíte anterior após cirurgia combinada de catarata e iStent inject®, além de orientações quanto ao manejo do quadro inflamatório.

ABSTRACT

ABSTRACT Objective To assess the economic impact of reducing glaucoma progression by using the trabecular micro-bypass implant, iStent inject®, in the Reference Centers for glaucoma treatment within the Brazilian Public Unified Health System (SUS). Methods In a cost-effectiveness analysis, a Markov model was developed, and the costs were obtained from the SUS perspective (medical direct costs). Effectiveness was measured in progression-free life-years. The time horizon was the mean life expectancy of the Brazilian population. The model parameters were obtained through a review and a critical analysis of the literature. The base case comprised a hypothetical cohort of patients with open-angle glaucoma, using anti-glaucoma eye drops and followed up at Reference Centers of SUS. We tested whether the incorporation of iStent inject® as an alternative second-line therapy would be cost-effective. The outcome measure was the incremental cost-effectiveness ratio (R$/progression-free life-years). We tested the robustness of the model by univariate and probabilistic sensitivity analyses. Results The use of iStent inject® led to decreased progression rate of glaucoma, evidenced by the amount of progression-free life-years obtained with each treatment strategy (7.82 progression-free life-years with iStent inject® versus 6.33 progression-free life-years with medical treatment), thereby improving glaucoma control. There was also a reduction in future costs associated with eye drops, filtering surgeries, and treatment complications. Incremental cost-effectiveness ratio ranged from R$ 6,429.30 to R$ 7,550.97/progression-free life-years. The model proved to be robust in the sensitivity analyses. Conclusion This analysis showed that iStent inject®, when used after the failure of the first-line therapy, is able to reduce the rate of glaucoma progression at an acceptable cost.


RESUMO Objetivo Avaliar o impacto econômico da redução da progressão do glaucoma pelo uso do implante de by-pass trabecular iStent inject® no ambiente dos Centros de Referência para tratamento do Sistema Único de Saúde (SUS). Métodos Em uma análise de custo-efetividade, elaborou-se um modelo de Markov, cujos custos foram obtidos a partir da perspectiva do SUS financiador (custos médicos diretos). A efetividade foi medida em anos de vida livres de progressão. O horizonte temporal foi a expectativa de vida média da população brasileira. Os parâmetros do modelo foram obtidos pela revisão e pela análise crítica da literatura. O caso base foi composto de uma coorte hipotética de portadores de glaucoma de ângulo aberto em uso de colírios antiglaucomatosos e em acompanhamento nos Centros de Referência do SUS. Testou-se se a incorporação do iStent inject® como alternativa à segunda linha de tratamento seria custo-efetiva. A medida de desfecho foi a razão de custo-efetividade incremental (R$/anos de vida livres de progressão). A robustez do modelo foi testada por meio de análises de sensibilidade univariada e probabilística. Resultados A utilização do iStent inject® proporcionou uma diminuição da velocidade de progressão do glaucoma, evidenciada pela quantidade de anos de vida livres de progressão obtida com cada estratégia de tratamento (7,82 anos de vida livres de progressão com iStent inject® versus 6,33 anos de vida livres de progressão com tratamento com colírios), melhorando, dessa forma, o controle do glaucoma. Houve ainda redução nos custos futuros associados aos colírios, às cirurgias filtrantes e às complicações do tratamento. A razão de custo-efetividade incremental variou de R$6.429,30 a R$7.550,97/anos de vida livres de progressão. O modelo mostrou-se robusto nas análises de sensibilidade. Conclusão O iStent inject®, quando usado após a falha do primeiro medicamento, é capaz de reduzir a taxa de progressão do glaucoma a um custo aceitável.

ABSTRACT

We describe the occurrence of bilateral iridocorneal endothelial (ICE) syndrome with glaucoma in a young girl with Down's syndrome. A 16-year-old girl with Down's syndrome was found to have secondary glaucoma in the right eye with features of progressive iris atrophy in both eyes. She was uncontrolled on maximum tolerable medical therapy for glaucoma. She underwent an uneventful trabeculectomy with mitomycin-C in her right eye. Scanning electron microscopy of the trabecular meshwork obtained in this case is described.

ABSTRACT

This study was performed to demonstrate the ultrasound, biomicroscopic and dimensional changes of angle structure after laser iridotomy (LI) and primary trabeculectomy (PT) in primary angle-closure glaucoma (PACG). Angle-opening distance at a point 500 (m from the scleral spur (AOD500), trabecular-iris angle (theta1), trabecular ciliary process distance (TCPD), ciliary process-iris angle (CPI), iris thickness (ID1, ID3), length of iris-lens contact distance (ILCD) and anterior chamber depth (ACD) were assessed before and after each procedure. Thirteen patients with LI and 16 with PT were prospectively enrolled. There were statistically significant increases in AOD500, theta1, and ILCD in both groups. CPI was decreased in both groups. ACD, TCPD, and iris thickness were not changed significantly. The changes in angle configuration after LI or PT may result more from alterations in aqueous pressure gradients across the iris and the changes of configuration were greater in the iris roots without rotation of ciliary body. However, we didn't find any significant differences in the changes of parameters between the two procedures.

ABSTRACT

Dezessete olhos portadores de glaucoma e catarata foram submetidos à cirurgia trílice: extraçäo extracapsular da catarata, implante de lente de câmara posterior e trabeculectomia. O período de seguimento estendeu-se por 3 a 18 meses. A acuidade visual melhorou em 100% dos casos e o controle da pressäo intra-ocular (Po <- 20 mmHg) foi obtido em 82%, sem medicaçäo. As complicaçöes foram discretas e raras. A técnica descrita parece ser uma boa opçäo para o tratamento do paciente portador de glaucoma e catarata
