PURPOSE To determine the efficacy and safety of latanoprost treatment for 1 year in glaucoma patients, and to evaluate the effects of switching from timolol to latanoprost therapy. METHODS Latanoprost 0.005% was topically applied once daily without masking for 6 months in 223 patients with elevated intraocular pressure after previous treatment with latanoprost once daily or 0.5% timolol twice...
Four masked examiners studied the usefulness of the glass-rod for estimating intraocular pressure (IOP) in a living, anesthetized rabbit eye manometrically set to 135 different random values. With training, the average error in IOP estimation improved from 7.42 +/- 5.56 mmHg to 5.13 +/- 4.48 mmHg. Gentle palpation of the corneal apex with a glass-rod provides tactile and visual clues that may a...
AIM To analyse ab interno trabeculectomy (AIT) with the trabectome and combined phacoemulsification with AIT (phaco-AIT) by Shaffer angle grade (SG). METHODS Prospective study of AIT and phaco-AIT with narrow angles of SG≤2 versus open angles ≥3. Outcomes included intraocular pressure (IOP), medications, complications, secondary surgery and success (IOP <21 mm Hg and >20% reduction without fu...
A linear viscoelastic finite element model was built to investigate factors that influenced the intraocular pressure (IOP) elevations due to micro-volumetric changes in the eye at three different rates. The viscoelastic properties of the cornea and the sclera, including the instantaneous modulus, equilibrium modulus, and relaxation time constants, parametrically varied to examine their effects ...
Recent technological developments have provided a tool for continuous intraocular pressure (IOP) monitoring for a period of up to 24 h in patients with open angle glaucoma.1 We have taken part in a randomized clinical trial in which 8 patients received continuous IOP monitoring for 24 h with hospital admittance. The inclusion criteria were having an age comprised between 18 and 85 years with si...
OBJECTIVE To compare the short-term and long-term efficacy of using releasable sutures vs conventional interrupted sutures for scleral flap suturing in trabeculectomy. DESIGN A prospective randomized study. SETTING A university-affiliated referral eye hospital. PATIENTS Thirty consecutive patients requiring trabeculectomy for uncontrolled primary glaucoma. INTERVENTION Fifteen patients ...
Both alpha- and beta-adrenergic antagonists have been utilized in an atempt to discern the site of action of prostaglandin (PG) and tetrahydrocannabinol (THC) in the eye. Both alpha- and beta-adrenergic antagonists (alpha-antagonists, phentolamine and phenoxybenzamine; beta-antagonists, propranolol and sotalol) cuased a dose-dependent reduction in intraocular pressure and blood pressure and inc...
An open label, multi-center, 6 months observational study of new fixed combination (travoprost 0.004%/timolol 0.5%), in order to evaluate both efficacy (intraocular pressure lowering) and tolerability (patient and investigator satisfaction) of two dosing regimens--evening (PM) and morning (AM). After screening for enrollment, to 40 patients (79 eyes with primary open angle glaucoma or ocular hy...
BACKGROUND The correlation between intracranial pressure (ICP) and intraocular pressure (IOP) is still controversial in literature and hence whether IOP can be used as a non-invasive surrogate of ICP remains unknown. The aim of the current study was to further clarify the potential correlation between ICP and IOP. METHODS The IOP measured with Goldmann applanation tonometer was carried out on...
