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.

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 […]

OBJETIVO: Avaliar o sinal de Seidel positivo e a penetração de tinta da Índia em incisões corneanas acessórias seladas por diferentes métodos. MÉTODOS: Quatro incisões de 1,5 x 1,5mm foram criadas em cada um dos quatro olhos provindos do banco de olhos. Em cada córnea, uma incisão foi mantida sem manipulação, enquanto que as outras três incisões foram seladas respectivamente com Nylon 10-0, cola de cianoacrilato e hidratação estromal. Foram realizados dois testes: Sinal de Seidel positivo e penetração da […]
