Retinal and choroidal thickness changes after single anti-vegf injection in neovascular age-related macular degeneration: Ranibizumab vs bevacizumab

PubMedID: 24803153Purpose: To evaluate and compare the effects of single intravitreal injection of ranibizumab and beva-cizumab on central retinal and choroidal thickness in patients with neovascular age-related macular degeneration (AMD).Methods: Forty eyes of 40 patients with neovascular AMD that underwent intravitreal injection of vascular endothelial growth factor inhibitors (anti-VEGFs) were included. Patients were randomized into 2 groups: 20 eyes received ranibizumab and 20 eyes received bevacizumab injection. Central retinal and choroidal thicknesses of all eyes at baseline and 1 month postinjection scans were measured with Fourier-domain optical coherence tomography (OCT). Student t test and Mann-Whitney U test were used to compare the data.Results: The mean central retinal thickness (CRT) showed significant decrease after single injection of ranibizumab (from 345.0 µm to 253.5 µm, p<0.01) and bevacizumab (from 329.5 µm to 251.0 µm, p<0.01) at the first month, respectively. There was no significant difference regarding the CRT change between groups (p = 0.39). The mean choroidal thickness decreased from 158.6 µm (115-317) to 155.5 µm (111-322) in the ranibizumab group and from 211.5 µm (143-284) to 201.5 µm (93-338) in bevacizumab group. The decrease was not significant between groups (p = 0.35).Conclusions: Intravitreal injection of both ranibizumab and bevacizumab provided a significant decrease in CRT; however, the agents caused no significant change in choroidal thickness. Additionally, no difference between ranibizumab versus bevacizumab was observed related to macular edema inhibition. © 2014 Wichtig Publishing

Avaliação do risco nutricional em idosos atendidos por Equipes de Saúde da Família Evaluación del riesgo nutricional en ancianos atendidos por Equipos de Salud de Familia Evaluation of the nutritional risk in elderly assisted by Family Health Teams

Alterações do estado nutricional contribuem para o aumento da morbi-mortalidade em idosos. O instrumento The Nutrition Screening Initiative (NSI) foi desenvolvido para identificar riscos nutricionais nesse grupo populacional. Este estudo tem por objetivos descrever o perfil sociodemográfico e avaliar o risco nutricional de idosos atendidos por equipes da Estratégia Saúde da Família. O estudo é transversal, com amostra de 503 idosos residentes em Dourados (MS). Instrumentos: NSI e questionário estruturado para as variáveis sociodemográficas de saúde. Verificou-se o predomínio de idosos do sexo feminino, entre 60 a 69 anos, viúvos, analfabetos, de renda per capita de até um salário mínimo, com hipertensão e auto-avaliação regular de saúde. O NSI permitiu identificar 33,2% de idosos com alto risco nutricional, o que se mostrou significativamente associado ao baixo nível de escolaridade, à baixa renda per capita e às doenças crônicas. Como método de rastreio, o NSI mostrou-se útil para identificar os determinantes sociais e de saúde que contribuem para o risco nutricional.<br>Las alteraciones del estado nutricional contribuyen en aumentar la morbimortalidad en ancianos.

The instrument Nutrition Screening Initiative (NSI) was developed in order to identify nutritional risks in this population group. This study aims to describe the socio-demographic profile and evaluate the nutritional risk of the elderly assisted by Family Health Strategy teams. It is a cross-sectional study with a sample of 503 older people living in Dourados (MS). Instruments: NSI and structured questionnaire for the health socio-demographic variables. There was a prevalence of female people, aged between 60 and 69 years old, widowers, illiterate, with a per capita income up to one minimum salary, with hypertension and regular health self-evaluation. The NSI allowed to identify 33.2% of the elderly with high nutritional risk, which was significantly associated to the low level of education, low per capita income and chronic diseases. As a tracking method, the NSI was useful to identify the social and health determinants that contribute to the nutritional risk

Intravitreal Dexamethasone Implant in Retinitis Pigmentosa-related Cystoid Macular Edema

Purpose: To report the clinical outcome after intravitreal dexamethasone implant in patients with retinitis pigmentosa and cystoid macular edema. Methods: Multicenter retrospective case series of eyes with retinitis pigmentosa and cystoid macular edema that underwent intravitreal dexamethasone implant. Primary outcome measures were best-corrected visual acuity in LogMAR and central macular thickness. Statistical analyses used two-tailed comparison with Wilcoxon signed-rank test. Results: There were a total of 45 eyes from 34 patients with a mean age of 32.7 years (range 16-57) and mean follow-up of 15.5 ± 13.0 months. At Month 3 after the first injection, mean initial best-corrected visual acuity improved from 0.61 ± 0.38 (20/81) to 0.37 ± 0.16 (20/47) (P = 0.012), whereas mean central macular thickness (m) decreased from 506 ± 288 m to 311.7 ± 71.6 m (P < 0.001) and mean intraocular pressure increased from 15.7 ± 2.3 mmHg to 19.8 ± 11.0 mmHg (P = 0.01). Fourteen eyes had multiple injections (1-7 reinjections) at a mean interval of 6 months. Treatment effect was durable with multiple injections, but with seven eyes developing visually significant cataracts. Conclusion: Best-corrected visual acuity improved up to 4 months in around half of the eyes. Eyes that benefited the most were pseudophakic, steroid nonresponsive, with large initial central macular thickness, and profuse fluorescein dye leakage. © Ophthalmic Communications Society, Inc

Hypotony in Patients with Uveitis: The Multicenter Uveitis Steroid Treatment (MUST) Trial

PURPOSE: To assess the prevalence of hypotony in patients with severe forms of uveitis. METHODS: The Multicenter Uveitis Steroid Treatment (MUST) Trial, a randomized study, enrolled 255 patients. Patients with hypotony at the baseline visit were identified. RESULTS: Twenty (8.3%) of 240 patients with sufficient data had hypotony. Hypotony was more common in patients with uveitis ≥5 years duration (odds ratio [OR] = 5.0; p < .01), and in eyes with a history of ocular surgery (vitrectomy vs. none, OR = 3.1; p = .03). Hypotony was less in patients with older age of uveitis onset (>51 years vs. <51 years, OR = 0.1; p = .02), in Caucasian patients (OR = 0.1; p < .01) compared to African American patients. Hypotonous eyes were more likely to have visual impairment (OR = 22.9; p < .01). CONCLUSIONS: Hypotony is an important complication of uveitis and more commonly affects African-American patients, those with uveitis onset at a younger age, and those with longer disease duration. It is associated with visual impairment

Sports-Related Injuries of the Anterior Segment

Sports-related eye injury is a significant cause of morbidity and disability and accounts for a significant proportion of ocular trauma, especially in the young. Although some sports-related ocular injuries can be self-resolving and require little to no intervention, many other injuries have long-term sequelae that require extensive treatment and follow-up. A thorough evaluation of the mechanism of and circumstances surrounding the ocular injury is important to guide further management of the case. Blunt trauma has a significantly different pathophysiologic process compared to trauma by a sharp object, and the evaluation of the injury should be cognizant of the ocular trauma expected. The conjunctiva is most frequently involved in sports-related ocular injuries, and the nature of the conjunctival injury can often indicate involvement of other potential ocular structures. Examples of other anterior segment injuries that can result from sports-related ocular trauma include structural or functional damage to the cornea, iris injury leading to iris prolapse or laceration, ciliary body injury resulting in ciliary body detachment, lens injury resulting in cataract or subluxation/dislocation of the lens, and traumatic glaucoma. In this chapter, we provide a comprehensive review of the pathogenesis, clinical findings, treatment options, and prognosis of sports-related injuries of the anterior segment
