OBJECTIVE To assess clinical outcomes and establish the incidence and management of a hypertensive phase (HP) (defined as intraocular pressure [IOP] > 21 mmHg in the first 6 postoperative months) in patients with Ahmed glaucoma valve implant. DESIGN Retrospective noncomparative case series. PARTICIPANTS A total of 85 patients were included in the(More)
The adult mammalian temporomandibular joint (TM) disc is a fibrocartilaginous tissue that undergoes normal developmental remodeling, requiring removal of the existing extracellular matrix and its replacement by new matrix macromolecules. This remodeling is probably mediated by matrix-degrading enzymes, but to date none has been demonstrated in association(More)
Children with juvenile rheumatoid arthritis or juvenile chronic arthritis often exhibit temporomandibular joint (TMJ) involvement accompanied by pain, dysfunction, and growth abnormalities. Despite the severe functional and developmental consequences of this disease, its pathogenesis remains poorly understood, but important insights may be provided by a(More)
PURPOSE To assess clinical outcomes in patients who were treated with the Baerveldt glaucoma drainage implant. METHODS The authors performed a retrospective multicenter study of 100 patients (103 eyes) with medically uncontrollable glaucomas who underwent a one-stage implantation with either the 200-, 250-, 350-, or 500-mm2 Baerveldt implant. The authors(More)
BACKGROUND AND OBJECTIVE To compare double-plate Molteno (DPM) with the Ahmed glaucoma valve (AGV) in the treatment of eyes with complicated glaucoma. PATIENTS AND METHODS This matched, retrospective, case-control study was based on diagnosis, number of previous operations, and age. There were 30 patients in each group and only patients with a minimum of(More)
BACKGROUND Vitamin C or ascorbate is important in wound healing due to its essential role in collagen synthesis. To study wound healing in the periodontium, cells adherent to expanded polytetrafluoroethylene (ePTFE) augmentation membranes, recovered from edentulous ridge augmentation procedures, have been established in culture in our laboratories. The(More)
Guided tissue regeneration is a clinical procedure used to restore mineralized tissue that has been lost to periodontal disease or after tooth extraction. The procedure makes use of Gore-tex membranes or Gore-tex augmentation membranes (GTAM) to prevent migration of keratinocytes and gingival fibroblasts into healing wounds. To begin to characterize the(More)
PURPOSE To describe four patients who developed cystoid macular edema shortly after onset of treatment with latanoprost. METHOD Retrospective review of medical records of patients with open-angle glaucoma who developed cystoid macular edema shortly after starting latanoprost. RESULTS The use of topical latanoprost was temporally related to the(More)
