PURPOSE We investigated the correlation between 24-hour IOP in the habitual (sitting during day and supine during night) position (H24h-IOP) and IOP after a postural-change test (PCT-IOP) and a water-drinking test (WDT-IOP). We also investigated ocular and systemic factors related with them in patients with normal tension glaucoma (NTG). METHODS Japanese NTG patients underwent H24h-IOP, PCT-I...

purpose: to assess alterations in parameters measured by the ocular response analyzer (ora) after photorefractive keratectomy (prk) with or without 0.02% mitomycin c (mmc) in myopic eyes. methods: in 33 right eyes of 33 patients, iop was determined using the goldmann applanation tonometry (gat) before and 3 months after prk. corneal hysteresis (ch), corneal resistance factor (crf), goldmann-cor...

purpose: although there are ample evidences for the effects (mostly decrease) of intraocular pressure (iop) after the administration of atracurium and cisatracurium during general anesthesia in ophthalmic operations, no study has yet been done to compare their effects on both iop and pupillary diameter (pd) simultaneously. the aim of this study was to determine whether there is any difference b...

purpose : to evaluate the intraocular pressure (iop) rising effect of anterior versus posterior subtenon injection of triamcinolone in eyes with retinal vein occlusion methods : this prospective nonrandomized study was performed on 57 eyes of 57 patients with macular edema due to retinal vein occlusion. 26 eyes received posterior subtenon injection of 40 mg triamcinolone acetonide [pstt] and 31...

Objective: Retinopathy is a microvascular complication of diabetes in the retina. It is hypothesized the aqueous flow decrease in patients with retinopathy which effects the Intra-ocular pressure (IOP). The purpose of this study is to determine whether a significant correlation exists between IOP and diabetic retinopathy grades. Materials and Methods: Our study is analytic cross sectional. Abo...

Background: In many clinical situations, knowledge of central venous pressure (CVP) is important.  Measurement of CVP is not always possible. Objective: To determine if intraocular pressure (IOP) can be used as an estimate for CVP. Methods: IOP and CVP were measured concurrently in 30 candidates of coronary artery bypass graft surgery.  Those with carotid artery or jugular venous diseases as we...

PURPOSE We studied the relationship between nocturnal habitual position IOP elevation and diurnal IOP level in normal-tension glaucoma (NTG) patients. METHODS A total of 70 young NTG patients with a low diurnal IOP level (mean diurnal seated IOP < 15.0 mm Hg; low IOP group) and 79 age-, axial length-, and disease severity-matched NTG patients with a high diurnal IOP level (mean diurnal seated...

PURPOSE We investigated correlations between short-term and long-term intraocular pressure (IOP) fluctuations. METHODS We examined 50 eyes of glaucoma patients who were followed for >2 years. We measured short-term IOP fluctuation using a Triggerfish(®) contact lens sensor (CLS). The short-term IOP fluctuation (mVeq) was defined as the difference between the maximum value and the minimum valu...
