Os hemangiomas cavernosos são os tumores intraorbitais mais comuns encontrados em adultos de meia-idade. Embora histológico benigno, eles podem invadir a área orbital ou intraorbital ou ainda as estruturas adjacentes (nervo óptico) e ser considerado anatomicamente ou posicional maligno. Apresentamos um relato de caso de hemangioma cavernoso orbital da órbita direita em mulheres jovens após a gravidez, a partir de Topola perto Kragujevac (Central Sérvia), com comprometimento visual e medicado por tratamento cirúrgico endoscópico transnasal. O paciente foi controlado e […]

We have read with great enthusiasm the recently published article entitled ”Use of intravitreal bevacizumab or triamcinolone acetonide as a preoperative adjunct to vitrectomy for vitreous haemorrhage in diabetics” by Ferraz et al.1. We congratulate the authors for their lightening study. In that well-designed study, Ferraz and coworkers tried to evaluate the effect of preoperative intravitreal bevacizumab (IVB) or triamcinolone (IVT) on the rate of early postvitrectomy hemorrhage in proliferative diabetic retinopathy (PDR). They concluded that intravitreal injection of bevacizumab […]

Ethics is the set of principles that guide human behavior in society. Medical ethics is a subject that evaluates intellectual worth and risks in the activities of medicine. Or better, it is a set of rules that defines limits in the relationship of doctors and their pairs, because medical practice involves much more than only technical aspects shown in other professions. Yet, medical ethics would be the rules that prevent the doctor from deliberately take advantage of his special condition […]

PURPOSE: To test whether corneal hysteresis (CH) and corneal resistance factor (CRF) can discriminate between keratoconus and normal eyes and to evaluate whether the averages of two consecutive measurements perform differently from the one with the best waveform score (WS) for diagnosing keratoconus. METHODS: ORA measurements for one eye per individual were selected randomly from 53 normal patients and from 27 patients with keratoconus. Two groups were considered the average (CH-Avg, CRF-Avg) and best waveform score (CH-WS, CRF-WS) groups. The […]

OBJETIVO: Testar se a histerese corneana (CH) e o fator de resistência corneano (CRF) podem discriminar olhos com ceratocone e avaliar se a média de duas medidas consecutivas apresenta desempenho diferente da medida única com a melhor waveform score para diagnósticar o ceratocone. MÉTODOS: Foram realizadas medidas do ORA de um olho por indivíduo, selecionados aleatoriamente a partir de 53 pacientes normais e de 27 pacientes com ceratocone. Dois grupos foram considerados: a média (CH-médio, o CRF-médio) e melhor waveform […]

PURPOSE: To evaluate the effect of corneal crosslinking (CXL) in the treatment of infectious keratitis resistant to medical treatment, and investigate the relation with the CXL outcome to the etiologic agent. METHODS: The study included 11 patients who were diagnosed with bacterial (seven eyes) or fungal keratitis (four eyes) at Altino Ventura Foundation from october 2011 to may 2012. All patients were using antibiotic eye drops for at least 7 days and have had no infection improvement. Patients were evaluated […]

OBJECTIVE: To evaluate the clinical effects of lips salivary gland secretion as ocular lubricant for dry eye relief in mild cases, severe and refractory to medical treatment, through the transposition technique of salivary glands autograft to the conjunctival fornix. METHODS: Seventeen dogs exhibiting autoimmune dry eye with no satisfactory response to clinical treatment were selected. Lacrimal Schirmer Test and Tear Film break-up time (BUT) preoperative tests were performed to estimate the quantity and the quality of produced tear. Animals were […]

PURPOSE: To evaluate wound leakage and bacteria-sized particle influx in differently corneal sealed side port incisions. METHODS: Four 1.5mm tunnel squared incisions were created in each of four cadaveric human eyes. In each cornea, one incision was left unsealed, whereas the other three incisions were sealed using a 10-0 nylon suture, cyanoacrylate glue, or stromal hydration, respectively. A Seidel and an India ink test were performed on each eye. During each Seidel test, flourescein was applied, the IOP increased from […]
