The aim of this study was to compare the effects of ropivacaine with those of lidocaine on the intraocular pressure (IOP) and the quality of the blockade in peribulbar anesthesia for cataract surgery. Fifty patients were allocated randomly into two groups and received 7-10 ml of 0.75% ropivacaine or 2% lidocaine with adrenaline, though the peribulbar two-point injection. The quality of the bloc...

OBJECTIVE To evaluate the effect of the Valsalva maneuver (VM) during micturition on intraocular pressure (IOP) in patients with benign prostatic hyperplasia (BPH). PATIENTS AND METHODS IOP were measured before and during micturition in uroflowmetry testing by Tonopen-Avia (Reichert Inc., NY, USA) in 35 eyes of 35 patients with BPH. International Prostate Symptoms Score (IPSS) questionnaire w...

AIM To evaluate whether intraocular pressure (IOP) calculation by applanation tonometry is determined more essentially by the subject's neck position or by neck constriction. METHODS 23 right eyes of 23 healthy subjects (12 male, 11 female) were included. IOP was measured by applanation tonometry with the TonoPen on sitting participants under four different conditions: with open collar uprigh...

OBJECTIVE Anecdotal evidence has suggested that guinea pigs have a high prevalence of ocular lesions. Here we undertook a survey of 1000 guinea pigs from populations of animals kept as laboratory animals, breeding show cavies, animals kept as pets and those from rescue and rehoming centers. Each animal was examined to assess for ocular abnormalities. PROCEDURES A full ophthalmic examination w...

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...

PURPOSE To compare the effects of ropivacaine and bupivacaine-lidocaine combination on intraocular pressure, quality of block, and degree of postoperative pain in peribulbar block. METHODS The study group involved 32 patients undergoing elective cataract surgery under peribulbar block. Patients were divided into two groups according to the local anesthetic used: Group 1 (n=16), ropivacaine 0....

AIMS A prospective study was carried out in order to evaluate the efficacy and safety of peribulbar anaesthesia during keratoplasty and to describe surgical conditions. METHODS Of 137 consecutive keratoplasties, 100 (73%) were performed under peribulbar anaesthesia. Patients received a mean volume of 16.5 (SD 4) ml (range 9-22 ml) of a mixture of etidocaine, bupivacaine, and hyaluronidase. Oc...

AIM To describe the methods used and initial results of a prospective study designed to determine whether screening and prophylactic treatment will reduce the incidence of primary angle closure glaucoma (PACG) in Mongolia. METHODS A total of 4725 individuals aged 50 years and above were recruited to the study and randomised to intervention or control groups. All subjects had non-mydriatic opt...
