PURPOSE Choroidal detachment is a known complication of topical hypotensive agents when used to treat eyes sensitized by prior surgery. We document the abrupt development of an extensive choroidal detachment after initiation of dorzolamide therapy in a surgically untreated eye with primary open-angle glaucoma. DESIGN Observational case report. METHODS A 76-year-old woman with primary open-a...

Prior studies have shown that intravitreal daunorubicin (9-15 nmol) and triamcinolone acetonide (2 mg) are effective individually in preventing retinal detachment in experimental proliferative vitreoretinopathy. This report compares the efficacy of the combination of daunorubicin (15 nmol) and triamcinolone acetonide (2 mg) with that of daunorubicin alone in a refined experimental model of prol...

A conceptual model for colloid transport is developed that accounts for colloid attachment straining, and exclusion. Colloid attachment and detachment is modeled using first-order rate expressions, whereas straining is described using an irreversible first-order straining term that is depth dependent. Exclusion is modeled by adjusting transport parameters for colloid-accessible pore space. Fitt...

Field rainfall simulation experiments at two sites are used to partition sediment transport on unpaved roads into splash and hydraulic erosion components. Rain splash processes contributed 38–45% of total sediment output, with instantaneous contributions being variable throughout 60-min high-energy events. For lowand medium-magnitude rainstorms, splash erosion on roads is initially controlled b...

Papadopoulou et al are to be congratulated for submitting an informative article regarding the management of small choroidal melanoma with pertinent discussion and various educational points to remember. We were, however, surprised, not to find the use of OCT (optical coherence tomography) as part of the management to help the diagnosis or in the discussion section. The authors correctly highli...

The Attenuated Total Reflectance Fourier Transform InfraRed (ATR-FTIR) spectroscopy has been very early applied for studying biofilms, in situ, nondestructively, in real time, and under fully hydrated conditions. Because its analysis depth is very thin, typically of the order of 1-2 μm, the ATR-FTIR technique is an interesting tool for monitoring in situ, via the ATR-FTIR fingerprints of biomol...

BACKGROUND The mechanism underlying focal choroidal excavation (FCE) remains largely unknown. We evaluated the sequential progression of FCE generation using enhanced depth imaging optical coherence tomography (EDI-OCT) in a patient with multiple evanescent white dot syndrome (MEWDS). CASE PRESENTATION A 37-year-old woman suffered MEWDS in the right eye. EDI-OCT showed the loss of photorecept...

VITREOUS detachment is a constant accompaniment and thus a cardinal symptom of retinal detachment, the importance of which is being increasingly stressed by modern authors. It has been indicted as one of the causes of retinal detachment, its action being enhanced by vitreo-retinal adhesions, congenital or acquired. It is less known that all aphakic eyes show some degree of vitreous detachment, ...

A three-dimensional computer model was used to evaluate the effect of chemically mediated detachment on biofilm development in a negligible-shear environment. The model, BacLAB, combines conventional diffusion-reaction equations for chemicals with a cellular automata algorithm to simulate bacterial growth, movement and detachment. BacLAB simulates the life cycle of a bacterial biofilm from its ...
