PURPOSE The purpose of this study was to evaluate the intermediate surgical results of Ahmed glaucoma valve (AGV) implantation in patients less than 7 years of age, with advanced primary congenital glaucoma who have failed previous surgeries. PATIENTS AND METHODS Consecutive patients with advanced primary congenital glaucoma that failed previous operations and had undergone subsequent AGV imp...

Mahelkova et al. recently published an interesting study evaluating the corneal structures in buphthalmic eyes and healthy eyes in patients with unilateral congenital glaucoma by using confocal microscopy. The authors reported statistically significant increase of the basal epithelial cell density and significant reduction of the endothelial cell density in the buphthalmic eyes, whereas the dif...

Cardiopulmonary bypass (CPB) in a patient with glaucoma is a challenge. The glaucomatous eye is at risk during CPB. We report a case of ostium secundum atrial septal defect that was not amenable to device closure. The unique feature in the patient was the presence of congenital glaucoma. She was blind in the left eye, and the visual acuity in the other eye was decreased because of glaucoma. She...

Introduction: primary open-angle glaucoma (POAG) is a chronic and progressive anterior optic neuropathy characterized by perimetric alterations pathological excavation of the disc in absence other ocular pathologies or congenital anomalies. It usually accompanied an increase intraocular pressure. Gonioscopic examination confirms that iridocorneal angle open. The term "risk factor" defined as co...

A RAISED intra-ocular pressure associated with decreased outflow facility, a progressively enlarging cornea, and atrophy of the optic nerve have been described in neonatal infants born to mothers who acquired rubella during the first trimester of pregnancy (Swan, Tostevin, Moore, Mayo, and Black, 1943; Rones, 1944; Long and Danielson, 1945; Prendergast, 1946; Guerry, 1946; Irvine, 1946; Bardram...

T,he symposium was opened by a brief report on the recent conference on oxygen use in premature infants. J. Everett Kinsey, Ph.D., and Arnall Patz, M.D., stated that more oxygen was being used at present in order to decrease infant deaths. Dr. Patz recommended routine ophthalmoscopy of premature infants receiving oxygen. If excessive oxygen is being given, the retinal arterioles will show extre...

Dear Editor: Miyamoto et al show that intravitreal triamcinolone reduces macular edema as early as 1 hour after injection. They suggest that the time pattern demands that nongenomic mechanisms must be involved in the therapeutic effect of triamcinolone on retinal edema. Vasogenic edema in all tissues, including the retina, may be understood in terms of Starling’s law, by which the balance of hy...

OBJECTIVE To analyze data on the pediatric population attending the Ophthalmologic Clinic's Low Vision Service at the São Paulo University Medical School. METHODS Low vision ophthalmologic assessment, from April 1998 to December 2003, of 385 children and adolescents with mean age of 7 years; 51.7% males and 48.3% females. The main data analyzed were age, diagnosis, anatomic site of the ocular...

THIS series comprises foturteen cases, in which 2F') eyes were operated on. The timile over which the eyes were under observation after operation varied from seven years to twxo miontlhs. Tlihree of the cases were reported in a previous coimniunicatioin (M\IcA.revev, 1948); their subsequenit history is now followsed up. As a cause of blindness in eairllife, congenital glaucoma has a high incide...
