BACKGROUND To evaluate the short-term reproducibility of diurnal intraocular pressure (IOP) and ocular perfusion pressure (OPP) measurements in normal volunteers, untreated normal-tension glaucoma (NTG) and primary open-angle glaucoma (POAG) patients. METHODS Fifty-four healthy volunteers (control group), 67 NTG patients and 54 POAG patients were recruited. The IOPs of both eyes were measured...

Trabeculectomy is a gold standard filtration procedure in the management of glaucoma. However, small incision cataract surgery with trabeculectomy combined surgical for coexisting glaucoma and cataract. The final success rate related to minimizing intraocular pressure (IOP) depends on follow-up duration assessment criteria. This study was aimed evaluate long term control morphology bleb cases u...

PURPOSE To compare intraocular pressure (IOP) measured using the Ocular Response Analyzer (ORA; Reichert Ophthalmic Instruments, Buffalo, NY) with that measured using the Goldmann applanation tonometer (GAT) in keratoconic eyes after deep anterior lamellar keratoplasty (DALK) and evaluate the influence of central graft thickness (CGT), corneal astigmatism, corneal hysteresis (CH), and corneal r...

purpose : to evaluate the efficacy and safety of subconjunctival oculusgen implantation when used during trabeculectomy methods : in this prospective, nonrandomized, interventional case series, 10 eyes of 10 patients with medically uncontrolled open angle glaucoma were enrolled. conventional fornix based trabeculectomy with implantation of subconjunctival biodegradable collagen implant (oculusg...

PURPOSE To evaluates the role of measuring intraocular pressure (IOP) outside office-hour in primary adult onset glaucoma. METHODS This retrospective study included 100 cases of primary adult onset glaucoma. IOP readings obtained with Goldmann applanation tonometry between 7 am and 10 pm were compared to office-hour readings. RESULTS One hundred patients were enrolled (mean age: 58.64 ± 10....

BACKGROUND Corneal biomechanical properties are always compromised after corneal refractive surgeries thus leading to underestimated intraocular pressure (IOP) that complicates the management of IOP. We investigated the changes in postoperative baseline of IOP values measured with noncontact tonometer (NCT), ocular response analyzer (ORA) and corvis scheimpflug technology (CST) in the early pha...

PURPOSE To determine the relationship between dynamic contour tonometry (DCT), Goldmann applanation tonometry (GAT) and pneumotonometry (PNT) in ocular hypertension patients (OHT) and their relationship to central corneal thickness (CCT) and ocular pulse amplitude (OPA). METHODS Sixty patients (101 eyes) with intraocular pressure (IOP) ≥21 mmHg using GAT and normal appearing optic nerve heads...

PURPOSE To test the putative role of A(3) adenosine receptors (ARs) in modulating intraocular pressure (IOP). METHODS IOP was monitored for up to 32 minutes in A3-knockout (A3AR-/-) and A3AR+/+ control mice by the servo-null approach. The IOP responses to adenosine, A3AR agonists and A3AR antagonists were studied singly or in combination in both strains. RESULTS IOP was significantly lower ...

Abstract Background: The aim of this study was to evaluate the efficacy and safety of phacoemulsification and the implantation of intraocular lenses (IOL) combined with trabeculectomy supplemented by releasable sutures and antimetabolite agents. Methods:Phacotrabeculectomy was performed in 36 eyes of 30 patients who hadmedically uncontrolle...
