Filter by:We aim to investigate the effect of spinal anesthesia on intraocular pressure.
The investigators conduct this study to access the effect of corneal edema (the investigators are particularly interested in those who have the clinical central corneal edema) on the variation of intraocular pressure values measured by 3 commercial-available tonometers compare to the current gold standard tonometer; Goldmann applanation tonometer.
The Nevanac product information insert says that it can cause increase in eye pressure in 5-10% of patients. There is very little published literature on the effect of topical Nepafenac eye drops on eye pressure in normal people. The purpose of our study is to report this effect with a working hypothesis that there is no increase in eye pressure following use of Nepafenac eye drops.
Pediatric glaucoma is a rare but potentially blinding condition where the pressure in the eye is too high. Diagnosis is based on intraocular pressure (IOP) and assessment of the optic nerve, cornea and other structures. Accurate intraocular pressure measurements in young children is often impossible to obtain in an office setting. Children need sedation or general anesthesia to determine IOP. All volatile general anesthetics affect the IOP. Nitrous Oxide, a weak volatile anesthetic, does not affect IOP in healthy adults. Since Nitrous Oxide has shown to be safe and effective in a variety of practice environments, we want to evaluate the use of nitrous oxide in oxygen to obtain IOP measurements in children.
The purpose of the study is to investigate the IOP difference between normal and glaucomatous eyes using standard ophthalmic tonometry devices while subjects are performing different standard yoga asanas. The IOP of participants will be measured prior, immediately at start of the asana, 2 minutes into the asana, and immediately after assuming a sitting position. The patient will wait 10 minutes and a final IOP will be taken. Four standard yoga asanas will be tested.
The objective of this study is to evaluate the effect of latanoprostene bunod dosed once daily (QD) in reducing intraocular pressure (IOP) measured over a 24-hour period in healthy subjects.
Phacoemulsification is a quick method with less complication for cataract surgery. Due to the use of ultrasonic energy, it produced more post-operative inflammation than other methods. Many routes of steroid had been used to control post-operative inflammation. The investigators here compare the efficacy of single depot steroid subtenon injection (20-mg triamcinolone) with four-time-a-day steroid eye drop (0.1% dexamethasone) in controlling inflammation after uneventful phacoemulsification.
The goal of the study is to determine the effect of different doses of caffeine on intraocular pressure. We hypothesized that higher dosage of caffeine would increase intraocular pressure more than lower doses. Eligible subjects will be randomized into three groups: 1. group 1: intake of decaffeinated coffee 2. group 2: intake of coffee with lower caffeine dose 3. group 3: intake of coffee with higher caffeine dose Intraocular pressure will be measured at 0, 30, 60 and 90 minutes after coffee intake.
The purpose of the study is to compare the measurement of pressure inside the eye using three different FDA-approved devices (Icare, Tonopen, and Goldmann applanation).
- Transcleral cyclophotocoagulation (TSCPC) has long been used as refractory glaucoma management and is very easy to learn and easy to perform. - Recent advances in laser technology; the role of TSCPC is being expanded because it has benefits of noninvasive glaucoma procedure. - The titration (pops), the fixed high-energy, and the fixed-low energy (slow-coagulation) are three energy delivery techniques. - The present study would report on the outcome (efficacy and safety) of the slow-coagulation versus the titration method in treatment of refractory glaucoma with dark iris. - The results would provide reliable evidences to supplement clinical judgment when making a decision in favor of each treatment method for glaucoma patients.
