PURPOSE To describe a group of patients with dense visual field defects following macular hole surgery. METHODS Nine (7%) of 125 patients reviewed noted onset of dense visual field defects following uncomplicated vitrectomy with gas-fluid exchange for the treatment of macular hole. Patient records were reviewed to investigate the etiology of these(More)
Dissolution efficiency (D.E.), the area under a dissolution curve between defined time points, and the fit factors (f1 and f2) have been compared for the characterisation of dissolution profiles, using data from three batches of a product in nine different packs stored under two conditions. The factors f1 and f2 offer ease of calculation and a simple(More)
OBJECTIVE To determine whether patients with ocular hypertension (OHT) have elevated motion perimetry thresholds. DESIGN Motion perimetry uses a customized computer graphics program to detect the ability to identify a coherent shift in position of 50% of dots in a defined circular area against a background of fixed dots. Motion size threshold is defined(More)
Clinical observations suggest that patients with keratoconus have lower intraocular pressures, on average, than normal subjects. Our purpose was to determine whether differences in aqueous production and outflow facility could account for differences in intraocular pressure between a group of patients with keratoconus and a group of normal, age-matched(More)
Turcot syndrome is a hereditary condition characterized by multiple, adenomatous gastrointestinal polyps associated with neuroepithelial tumors of the central nervous system. The authors examined a patient with Turcot syndrome who had multiple regions of congenital hypertrophy of the retinal pigment epithelium (CHRPE) with areas of surrounding(More)
Mifepristone is a specific glucocorticoid receptor antagonist that has been shown to lower intraocular pressure modestly when applied topically to rabbit eyes. We evaluated the ability of mifepristone to block specific in vitro glucocorticoid receptor binding of the labeled agonist triamcinolone acetonide in cytosol isolated from rabbit iris-ciliary body(More)
BACKGROUND The efficacy of Baerveldt implant (Pharmacia & Upjohn, Inc., Kalamazoo, Mich.) surgery in the treatment of advanced childhood glaucoma is unknown. METHODS We reviewed the results of 23 consecutive 350 mm Baerveldt implants in 20 eyes of 17 children. Results were classified as follows: (1) success; no further reoperation, no decrease in vision,(More)
One hundred eyes of 100 patients in whom Tenon's cysts (TCs) developed in the early postoperative period following trabeculectomy with mitomycin C were retrospectively studied to determine their incidence, possible risk factors associated with their development, and the clinical course of the patients in whom they occurred. The incidence of TC formation was(More)
We have developed a technique of detecting and recording iris transillumination defects using an infrared sensitive video camera. This method is useful for assessing the loss of posterior iris pigment in patients with the pigmentary dispersion syndrome and pigmentary glaucoma. Some patients with no transillumination defects on slit-lamp examination were(More)
