purpose: to evaluate the early and intermediate outcomes of ahmed glaucoma valve implantation in pediatric glaucoma at labbafinejad medical center. methods: this was a retrospective chart review of 101 eyes of 80 consecutive patients with pediatric glaucoma who underwent ahmed glaucoma valve implantation. success was defined as an intraocular pressure less than 21 mmhg with or without medicatio...

BACKGROUND Corneal endothelial damage is a known complication of aqueous shunt surgery. OBJECTIVE To describe a new technique for repositioning the Ahmed glaucoma valve tube in a case of tube-endothelial touch. CASE A patient with advanced glaucoma, having undergone Ahmed glaucoma valve (AVG) implantation, developed localized corneal endothelial damage due to contact between the tube and su...

Optical coherence tomography (OCT) is a commonly used imaging modality in the evaluation of glaucomatous damage. The commercially available spectral domain (SD)-OCT offers benefits in glaucoma assessment over the earlier generation of time domain-OCT due to increased axial resolution, faster scanning speeds and has been reported to have improved reproducibility but similar diagnostic accuracy. ...

For quite some time, glaucoma has been regarded as more than just intraocular pressure [IOP] elevation. Significant contribution to this conceptual improvement has risen from a better understanding of ocular blood flow, vessel wall integrity and certain advanced ideas in neuroophthalmology, for example neuroprotection. Transforming growth factor-β (TGF-β) molecule, its inhibitors and antagonist...

PURPOSE A 1986-1987 survey found an 8.8% prevalence of open-angle glaucoma in the black population of St Lucia, West Indies. This follow-up study assessed progression of visual field loss in untreated glaucoma patients and persons with suspected glaucoma 10 years later. METHODS Subjects were 205 patients with or suspected of having glaucoma. The 1987 data included age, sex, visual acuity, and...

Glaucoma is one of the principal causes of blindness in the world1. It is an illness which has an asymptomatic form until advanced stages, thus early diagnosis represents an important objective to achieve with the aim that people who present Glaucoma maintain the best visual acuity throughout life, thereby improving their quality of life. An Artificial Neural Network (ANN) is proposed for the d...

PURPOSE To investigate the clinical features of subjects with glaucoma with the E50K mutation in the optineurin (OPTN) gene and to compare the onset, severity, and clinical course of these patients with a control group of subjects with glaucoma without this mutation. METHODS The phenotype of well-characterized subjects from Moorfields Eye Hospital, London, who had been identified as carrying ...

Patients with glaucoma and glaucoma suspects encompass a large group of individuals—up to 5% of the population over the age of 40 years, and an even higher prevalence in older age groups. With aging of the Canadian population, the number of affected individuals with glaucoma or glaucoma suspects is expected to increase dramatically, placing significant stresses on the resources devoted to eye c...

Objectives: To determine the correlations between measurements obtained with Heidelberg retina tomograph III (HRT III), optic coherence tomography (OCT), and laser polarimetry (GDx) indices of automated perimetry (AP) in moderate severe glaucoma patients. Methods: Forty-nine eyes 30 patients were included current study divided into two groups: 23 26 defined by Hodapp-Parrish-Anderson grading sy...
