PURPOSE: To report a case of unilateral post trabeculectomy globe massage-induced keratoconus (KCN). CASE REPORT: A 52-year-old lady with a history of trabeculectomy due to iridocorneal endothelial syndrome in her right eye was instructed to massage her globe to control gradual rise of intraocular pressure 1.5 years after surgery. The patient experienced high astigmatism and marked inferior corneal steepening after 3 years of globe massage. The left eye was normal in all aspects...

PURPOSE: To evaluate the safety and efficacy of phacoemulsification for management of post-filtering ocular hypotony. METHODS: This prospective interventional case series study recruited 21 consecutive patients with an established diagnosis of ocular hypotony with or without maculopathy. Clear corneal incision phacoemulsification was done for all patients. Nineteen cases that completed a follow-up of at least 6 months were considered for final analysis. RESULTS: Mean baseline intraocular pressure (IOP) was 2...

PURPOSE: To assess variations in the corneal biomechanical properties in thyroid eye disease (TED) patients using ocular response analyzer (ORA). PATIENTS AND METHODS: In this observational cross-sectional study, 75 patients with TED and 57 healthy subjects were enrolled. The mean age of the patients and healthy subjects were 47.50±1.55 and 43.6±1.23 years, respectively (P=0.06). All study participants underwent comprehensive ophthalmologic examination, Goldmann applanation tonometry (GAT), corneal pachymetry, and corneal biomechanical analysis using ORA...

BACKGROUND: The overall aim of this study was to determine retinal venous pressure (RVP) in healthy chronic smokers and compare values to those of healthy non-smokers. METHODS: Both eyes of 25 healthy chronic smokers and 41 healthy non-smokers were included. Measurements of RVP were performed by means of contact lens ophthalmodynamometry. Ophthalmodynamometry is done by applying increasing force on the eye via a contact lens. If a spontaneous venous pulsation was present, it was noted...

PURPOSE: To investigate the outcome of trabeculectomy with or without adjunctive intracameral bevacizumab. MATERIALS AND METHODS: In this prospective, double-blind, randomized clinical trial, 71 patients with primary open-angle or pseudoexfoliation glaucoma were randomly assigned to receive either 1.25 mg intracameral bevacizumab (n=36) or balanced salt solution as placebo (n=35) at the end of trabeculectomy. Success was defined as at least a 30% drop in intraocular pressure (IOP) compared with baseline values and an IOP between 6 and 21 mm Hg at the last postoperative visit with (qualified) or without (complete) glaucoma medications...

A 14-year-old boy presented with a 6-month history of small white masses in his right eye. Examination revealed a white floating fluffy lesion and 2 vegetative hornlike white lesions originating at the periphery of the iris. On ultrasound biomicroscopy, a normal echogenic mass was detected on the inferior iris root and angle, with no posterior chamber or cilliary body involvement. Histopathology following an excisional biopsy revealed keratinous material. There was no recurrence during 10 months of follow-up...

BACKGROUND: To evaluate different mechanisms of acute angle closure and to compare it with unaffected fellow eyes and primary angle closure suspects using anterior segment optical coherence tomography. DESIGN: Prospective, cross-sectional. PARTICIPANTS: 116 eyes (76 patients) with angle closure disease were included. METHODS: Eyes were categorized into three groups: (i) acute angle closure (40 eyes); (ii) fellow eyes of acute angle closure (40 eyes); and (iii) primary angle closure suspect (36 eyes)...

PURPOSE: To evaluate ocular biometric parameters in different subtypes of angle-closure disease in the Iranian population and compare them with normal eyes. DESIGN: Prospective, cross-sectional. METHODS: In this clinic-based study, 189 eyes of 154 patients consisting of 40 acute angle-closure glaucoma (AACG) eyes, 40 fellow eyes of AACG, 42 chronic angle-closure glaucoma (CACG) eyes, 40 primary angle-closure suspect (PACS) eyes, and 27 normal eyes underwent complete examination including gonioscopy, A-scan biometry, and anterior segment optical coherence tomography...

Carotid artery pseudoaneurysm is a rare complication of injury to the head and neck, which has been traditionally managed by an open surgical repair to avoid the occurrence of devastating cerebral strokes. Their treatment presents a challenge because of the risk of serious neurological events. This report presents a case of a stab penetrating injury to the left upper neck (Monson`s zone-III), which resulted in ipsilateral seventh and twelfth cranial nerve palsy and contra lateral hemiparesis, and false aneurysm of the internal carotid artery...

PURPOSE: To evaluate the effectiveness of phacoemulsification with goniosynechialysis in the management of refractory acute angle closure (AAC). METHODS: In this prospective, noncomparative interventional case series, patients with AAC who were unresponsive to medical and laser therapy were included. Success was defined as complete if intraocular pressure (IOP) had a drop of at least 30% and was between 6 and 21 mmHg without medication, and qualified if IOP was within that range with medication...

Sub chronic exposure to lead in rats slows gastric emptying, but little is known about the effects of lead on gastric secretion. This study was designed to investigate the effects of lead on gastric acid secretion and its possible mechanisms in rats. Lead acetate was dissolved in drinking water in a concentration of 1%. Sodium acetate-containing water with a molar concentration similar to lead was also prepared. We had nine groups of animals (n=8); four of them were exposed to lead for 1, 2, 3, and 4 weeks (Pb1, Pb2, Pb3 and Pb4 groups, respectively)...

BACKGROUND/AIMS: Paraoxon, an organophosphate metabolite of the insecticide parathion inhibits the enzyme, acetylcholinesterase (Achase). Organophosphates affect the heart, visual system, nervous system and muscles. In this present study, we investigate the effects of the chronic consumption of paraoxon on gastric acid and pepsin secretion in N-mari rats. MATERIALS AND METHODS: This study was performed from April 2003 to May 2004 in the Physiology department of Baghiatalah University of Medical Sciences, Tehran, Iran...

Considering the high consumption rate of marjoram in the Iranian population, this study was designed to investigate the effects of marjoram extract on gastric acid and pepsin secretion. In this study, Wistar rats (n=12) were divided into two equal case and control groups. Under general anaesthesia with 50 mg/kg i.p. sodium thiopental, laparatomy was done and a cannula inserted in the duodenum. In the case animals marjoram (12.5 mg/kg) was injected into the stomach through the mentioned cannula. The gastric contents were collected by the wash-out technique...
