Glaucoma is the leading cause of irreversible blindness in Brazil. Its prevalence and incidence tend to increase significantly in the future, mainly due to the population increase and aging. The scarcity of health care resources and the increasing costs in health require a balanced analysis of health interventions and an efficient allocation of resources. The cost-effectiveness and cost-utility studies are important because they allow a comparison between different alternatives in terms of both their costs and their results. For this […]

Over the years, mitomycin C has been used by refractive surgeons to prophylactically decrease haze after surface ablation procedures and therapeutically in the treatment of preexisting haze. Development of mitomycin C treatments has had a significant role in the revival of surface ablation techniques. We reviewed the literature regarding mechanism of action of mitomycin C, its role in modulating wound healing after refractive surgery, and its safety and efficacy as adjuvant therapy applied after primary photorefractive keratectomy surgery or after […]

Glaucoma is a group of progressive optic neuropathies that have in common a slow progressive degeneration of retinal ganglion cells and their axons, resulting in a distinct appearance of the optic disc and a concomitant pattern of visual loss. Biomarkers are characteristics objectively measured and evaluated as indication of normal biologic processes, pathogenic processes, or pharmacologic responses to a therapeutic intervention. Several biological markers have been implicated with glaucoma, especially genetics, proteomics, autoimmune and other molecular biomarkers, although, most awaits […]

The corneal cross-linking has been used in order to reduce and stabilize the progression of ectatic diseases through its effects on the biomechanics of the cornea. Different protocols are being conducted worldwide to expand its indications as well as its use at different ages, different stages of the disease, combinations with other techniques, besides the utilization for non-ectatic diseases. There is still no consensus on the indications of the cross-linking procedure, but the results published in the literature show significant […]

Macular cystoid edema is one of the major causes of decreased vision after cataract surgery. The inflammatory process appears to be the main causal factor of the edema. The major risk factors are: surgical complications, previous retinal diseases, diabetes, uveitis and use of prostaglandins drops. The diagnosis is clinically, but fluorescein angiography and optical coherence tomography are also important to detect swelling and assist in differential diagnosis. Although pre-operative prophylaxis do not have scientific evidence, it is recommended especially in […]

O presente trabalho objetiva descrever o processo de doação, captação, fila de espera e transplante de órgãos e tecidos como uma das políticas de saúde no Brasil e no Estado do Rio de Janeiro, com ênfase nos procedimentos relativos aos transplantes de córnea. A baixa notificação de possíveis doadores e a alta taxa de negativa familiar na doação associado ao insuficiente número de córneas disponibilizadas por Banco de Olhos são os principais fatores que limitam o aumento do número dos […]

Diabetic retinopathy is the leading cause of blindness among the working population in the developed world. The prevalence of diabetic retinopathy increases with duration of diabetes, and nearly 100 percent of patients with type I diabetes and more than 60 percent of those with type II have some signs of diabetic retinopathy after 20 years.A number of approaches have proved to be useful in the treatment of diabetic retinopathy, such as laser photocoagulation and tight systemic control of blood glucose, […]
