ULTRA-WIDEFIELD AUTOFLUORESCENCE IMAGING IN THE EVALUATION OF SCLERAL BUCKLING SURGERY FOR RETINAL DETACHMENT

To investigate the use of ultra-widefield fundus autofluorescence imaging in the early postoperative evaluation of scleral buckling surgery for retinal detachment. Forty-five eyes from 44 patients with rhegmatogenous retinal detachment were included. Ultra-widefield fundus autofluorescence imaging (Optomap P200Tx) was performed from both eyes preoperatively and early (1-2 days) postoperatively. All patients were operated with 2.5-mm encircling band, 6-mm to 9-mm segmental buckle, transscleral cryopexy, and the choice of drainage and air/gas endotamponade. The mean age of the patients was 58 ± 12 years, and the ratio of macula on-off detachments was 19/26. Light cryopexy induced hyperfluorescence of the treated area (in 11% of cases). Moderate cryopexy resulted in central hypofluorescence with a hyperfluorescent halo (in 51% of cases), whereas extensive cryopexy and disruption of the retinal pigment epithelium resulted in a broad hypofluorescent area (in 36% of cases). Tightening of the indenting elements induced peripheral hyperfluorescent radial streaks in 47% of cases and distinct areas of hyperfluorescence in 58% of cases. Demarcation lines and residual subretinal fluid were observed as hyperfluorescent areas. Central autofluorescence changes were observed in 96% of macula-off surgeries, whereas only 27% of these cases showed distinct hyper- and hypo-autofluorescent streaks. Ultra-widefield fundus autofluorescence imaging is a useful adjuvant tool for evaluating early outcome and retinal pigment epithelium function after scleral buckling surgery for retinal detachment.

A Prospective Series Case Study of Pyogenic Liver Abscess: Recent Trands in Etiology and Management

Our study aims to review the literature on the management of pyogenic liver abscess, focusing on the choice of drainage. A case series of our experience with clinicopathological correlation is presented to highlight the indication and outcome of each modality of drainage. Intravenous antibiotic is the first line, and mainstay, of treatment. Drainage is necessary for large abscesses, equal to or larger than 5cm in size, to facilitate resolution. While percutaneous drainage is appropriate as first-line surgical treatment in most cases, open surgical drainage is prudent in cases of rupture, multiloculation, associated biliary, or intra-abdominal pathology. Percutaneous drainage may help to optimize clinical condition prior to surgery. Nevertheless, in current good clinical practices, the choice of therapy needs to be individualized according to patient's clinical status and abscess factors. They are complementary in the management of liver abscesses.

Pump Drainage in Carolina Bays

Small submersible electric pumps were used in conjunction with tile and surface-drainage systems for removing excess water from saucerlike basins at a reasonable cost. Only 0.67 in. (17 mm) of water per year was removed by the surface-drainage whereas 3.46 in (88 mm) were removed by the tile-drainage system. The water table was controlled below the rooting depth by both drainage systems, whereas water was ponded on the surface several times each year where no drainage system was provided. The bays drained by pump-assisted tile or surface-drainage systems were productive all year, while the lower portions of the undrained bays were nonproductive. The choice of drainage in Carolina bays should be based on the comparative installation cost of the two systems, anticipated additional income resulting from drainage, and the ability of the operator.
