purpose: to evaluate ocular biometric changes after phacotrabeculectomy and its effect on intraocular lens power calculation. methods: twenty six eligible eyes (24 patients) underwent phacotrabeculectomy. they were reexamined at least 6 months after the operation in a historical cohort study. main outcome measures included axial length (al) with contact a- scan (us-8000, nidek, gamaguri, japan)...

Background: To evaluate the agreement in intraocular pressure (IOP) measurements by Ocular Response Analyzer (ORA) and Tono-Pen XL (TXL) with the Goldmann Applanation Tonometer (GAT) and to examine corneal biomechanical properties in aphakic glaucoma patients with a central corneal thickness (CCT) >600 µ. Methods: Thirty-six eyes of aphakic glaucoma patients (group 1) and 40 eyes of normal chil...

purpose: to compare corneal biomechanical properties and intraocular pressure (iop) in eyes with pseudophakic bullous keratopathy (pbk) before and after descemet stripping automated endothelial keratoplasty (dsaek). methods: this prospective non-randomizedintrasubject comparative study was conducted on 44eyes of 22 patients with the diagnosis ofpbk who underwent dsaek in one eye.intraocular pre...

purpose: to evaluate the success rate and complications of single-plate molteno tube implantation in patients with intractable glaucoma. methods: this study was conducted on records of patients who underwent molteno tube implantation from 1995 to 2000 and had at least 18 months of follow-up. results: thirty six eyes of 35 patients including 20 male and 15 female subjects with mean age of 29.7±2...

BACKGROUND Several authors reported incorrect high intraocular pressure (IOP) values in eyes with a thick cornea using applanation tonometry. This hypothesis was checked by comparing applanation tonometry with direct intracameral manometry. METHODS 73 patients, scheduled for intraocular surgery, were enrolled. Immediately before surgery, the following were registered: (i) central corneal thic...

Purpose: To study the simultaneous effects of prone position and anesthesia on intraocular pressure (IOP) and the time impact on post anesthesia visual loss development in percutaneous nephrolithotomy (PCNL). Materials and Methods: Twenty patients who were candidates for PCNL were recruited in this study. Intraocular pressure was measured in five occasions: 1. Base line; 2. Ten minutes after an...

OBJECTIVE To assess 24-hour intraocular pressure (IOP) and ocular perfusion pressure rhythms in newly diagnosed apneic patients before and after nasal continuous positive airway pressure (nCPAP) treatment. METHODS Intraocular pressure (using a Tonopen XL) and ambulatory blood pressure, measured hourly for 24 hours, were analyzed in 18 consecutive patients with obstructive sleep apnea for nyct...

PURPOSE/AIM Glaucoma consists of a group of progressive optic neuropathies that are characterized by degeneration of the optic nerve and irreversible visual filed loss. Elevated intraocular pressure is the only proven treatable risk factor and commercial products used for glaucoma treatment are focused in lowering intraocular pressure. These drugs can have various undesirable side effects and t...

IntroductionThe Goldmann Applanation Tonometer (GAT) is accepted as the gold standard tool to measure Intraocular Pressure (IOP). Besides, there an emerging Icare Rebound (RBT) which can be alternative in terms of measuring IOP.ObjectiveThis research aimed analyze agreement, and repeatability intraocular pressure (IOP) measurements compare outcomes RBT GAT among Mzuzu University Students Malawi...

Open-angle glaucoma (OAG) is a common ocular abnormality seen in patients with end-stage renal disease (ESRD) [1]. Although the pathogenesis of OAG is not yet fully understood, lowering intraocular pressure is the accepted treatment goal. Without adequate treatment, glaucoma can lead to visual disability and eventual blindness [2]. From a simplified viewpoint, intraocular pressure is determined...
