Filter by:This is a prospective study of IOP in Intravitreal injections to evaluate: 1. IOP effect of intravitreal injection 2. IOP response to prophylactic beta blocker or Prostaglandin vs control (Hypromellose) over multiple time periods 3. IOP response in correlation to number of injections, IOL, type of anti VEGF, co morbidities
The purpose of this study is to assess the effects osteopathic techniques at the upper cervical vertebrae or at the sphenopalatine ganglia on the intraocular pressure.
The purpose of this study is to evaluate the safety and Intraocular pressure lowering effectiveness of the Streamline™ Surgical System.
The SALUS project is developing a new form of care, the application of self-tonometry by the patient itself, and an accompanying electronic case file connecting clinics, doctor's offices and patients.
The aim of this study is to examine the effects of intraoperative systemic use of dexmedetomidine on the intraocular pressure (IOP) in patients undergoing spine surgeries in a prone position under general anesthesia.
This study aims to evaluate the effect of topical prophylaxis with brinzolamide-brimonidine fixed combination on short-term intraocular pressure (IOP) elevation after intravitreal injections of anti-vascular endothelial growth factors (anti-VEGF). Patients scheduled for treatment with intravitreal injections of anti-VEGF will be randomly divided into two groups. In control group no prophylactic medication will be used, whereas in case group one drop of brinzolamide-brimonidine fixed combination will be instilled two hours before the injection. IOP will be measured before the injection, 1 minute after the injection, 10 minutes and 30 minutes post-injection in all eyes. In case group, the pre-injection IOP will be measured prior to the administration of the fixed combination of brinzolamide-brimonidine. The iCare (IC200) tonometer will be used for IOP measurements at all time points.
Assessing the efficacy and safety of DEXTENZA, sustained release dexamethasone 0.4 mg insert following corneal transplant surgery (PKP, DSEK, DMEK) as compared to topical prednisolone acetate 1%.
Glaucoma remains the leading cause of irreversible blindness worldwide. Glaucoma represents a group of diseases that lead to optic nerve damage and corresponding deterioration of the visual field. Elevated intraocular pressure remains the most important risk factor. Interestingly, glaucomatous damage sometimes occurs despite seemingly normal intraocular pressure. Recent studies suggest pressure peaks, which are missed under the current practice of spot intraocular measurements during office hours. In order to detect pressure peaks diurnal measurements are mandatory. Costly in-hospital diurnal measurements are the current standard. The primary study objective is to verify that self-tonometry at home can provide valuable information when looking for pressure peaks in patients with glaucoma.
Determine if the Tono-Vera Tonometer accurately measures intraocular pressure (IOP). The hypothesis of this test is to confirm the Tono-Vera Tonometer is equivalent to the Goldmann Applanation Tonometer (within +/- 5.0 mmHg).
The aim of this study is to determine the effectiveness of lowering intraocular pressure and safety profile of the Paul Glaucoma Implant (Advanced Ophthalmic Innovations, Singapore). This is a non-comparative and single-arm observational study and all the participants were recruited between 1 Dec 2017 and 1 Dec 2018. Patients between age 21 - 80 years with glaucoma and an IOP deemed poorly controlled by the study team despite on maximal tolerated medical therapy were included in this study. The participants were recruited from 6 tertiary ophthalmology centers including National University Hospital, Singapore, Moorfields Eye Hospital, United Kingdom, St Thomas' Hospital, United Kingdom, Chulalongkorn University and Hospital, Thailand, International Specialist Eye Centre, Malaysia and Chinese University of Hong Kong, Hong Kong. All the eyes were followed-up for a period of 12 months after surgery. The examination and investigations included best corrected Snellen visual acuity, slit lamp examination, goldman applanation tonometry (GAT), dilated fundus examination and optic nerve head imaging. The participants are reviewed before surgery, 1 day, 1 week, 1 month, three months, 6 months and 12 months after surgery. All the data were captured in a standardized data-collection form for analysis. The primary outcome measure was failure, if was prospectively defined as IOP more than 21mmHg or less than a 20% reduction compared to pre-operative baseline on 2 consecutive visits after 3 months, IOP less than 6 mmHg on 2 consecutive visits after 3 months, reoperation for IOP-related indication, loss of light perception vision, or removal of the implant for any reason. Intraocular pressure outcomes, number of IOP-lowering medications and the rate of surgical complications were secondary outcome measures in this study.
