OBJECTIVE A highly reflective layer seen in retinal optical coherence tomography (OCT) has been believed to correspond to the choriocapillaris (CHC) and retinal pigment epithelium (RPE). On gray-scale scans of OCT-2000, and on Stratus OCT, this layer by the outer retinal limit can be resolved into 2 distinct laminae. We analyzed these 2 laminae in normal(More)
PURPOSE Microglia normally exist in several layers across the retinal thickness. When retinal ganglion cells undergo apoptosis after lesion to their axons, microglial cells proliferate and promptly clear the debris. We have previously reported on the phagocytic response following optic nerve axotomy. Here, we present how microglial cells of deeper retinal(More)
PURPOSE The use of a temporary keratoprosthesis has allowed earlier surgical intervention in eyes with coexisting vitreoretinal and corneal disease. We analyzed our experience with this type of surgery. METHODS We retrospectively reviewed charts of patients in whom a temporary keratoprosthesis was used between 1987 and 1998. Analysis was focused on ocular(More)
Penetrating keratoplasty carries an infectious risk. Its requirement for topical corticosteroid therapy facilitates fungal growth with resulting keratitis. Although progression of fungal keratitis to intraocular infection is uncommon, endophthalmitis resulting from keratitis usually has a poor visual prognosis. Fungal infection under these circumstances(More)
PURPOSE To analyze factors that may lead to inadvertent subretinal retention of perfluorocarbon liquid (PFCL) after vitreoretinal surgery and compare surgical outcomes and complications associated with these events. DESIGN Consecutive retrospective study. METHODS The authors retrospectively reviewed the charts of 72 vitreoretinal surgeries using(More)
Coats' disease is an idiopathic disorder in which telangiectatic and aneurysmal retinal vessels leak a lipoproteinaceous exudate, with consequent bullous retinal detachment. It is a diagnostic challenge, and CT and MR imaging provide valuable information to differentiate it from other pathologies, particularly from retinoblastoma. Typical, advanced Coats'(More)
PURPOSE To describe a patient with postoperative endophthalmitis whose only abnormal finding at presentation was a vitreous hemorrhage. DESIGN Interventional case report. METHODS A 68-year-old diabetic woman underwent cataract extraction with intraocular lens implantation in the left eye. Three days after surgery, she had painless loss of vision,(More)
PURPOSE To determine which of the eye's refractive components are responsible for the high myopia in retinopathy of prematurity (ROP), as compared with highly myopic eyes in full-term patients. METHODS The study included 53 highly myopic eyes in 34 patients with a history of ROP, and 66 highly myopic eyes in 37 full-term patients. Measurements included(More)
PURPOSE To evaluate the thickness of the peripapillary retina in healthy subjects with different degrees of ametropia. DESIGN Cross-sectional study. PARTICIPANTS Forty-three healthy normal subjects, ages 15 to 64 years (38+/-15 years) were recruited. METHODS The method of retinal thickness mapping was applied to generate serial optical section images(More)
