PURPOSE Regulation of ocular blood flow might be impaired in glaucoma patients. We compared the reaction of retinal vessels to a short-term increase of intraocular pressure (IOP), using a retinal vessel analyzer (RVA), in normal volunteers, ocular hypertensive patients (OH) and primary open angle glaucoma patients (POAG). METHODS Ten healthy subjects (56+/-8 years, IOP 13.7+/-1.6 mmHg), 10 OH...

PURPOSE Retinal vessel analysis is affected by both systemic and ocular factors. Malays are the major ethnicity in South East Asia. Data on the retinal microvasculature in Malays is limited, especially among children. We aim to evaluate the influence of ocular biometry on retinal vessel parameters in young Malay girls. METHODS This was a cross-sectional, hospital-based study involving 86 Mala...

PURPOSE To investigate the effect of cilostazol on ocular hemodynamics and to determine whether the administration of cilostazol increases the ocular blood flow in patients with diabetic retinopathy. METHODS This prospective observational study investigated the effect of orally administered cilostazol on diabetic retinopathy. Before and after administration for 1 week, pulsatile ocular blood ...

PURPOSE To evaluate the clinical outcomes of aspheric ocular wavefront ablation profiles in LASIK treatments. METHODS Thirty eyes treated by ocular wavefront were retrospectively analyzed at 6-month follow-up. Custom Ablation Manager (CAM) software was used to plan wavefront-customized aspheric treatments, and the ESIRIS system was used to perform ablations (SCHWIND eye-tech-solutions). Outco...

PURPOSE To examine the changes in meibomian gland morphology and ocular higher-order aberrations (HOAs) in eyes with chalazion and its excision. METHODS Seven male patients with previous history of chalazion excision and seven control male subjects were enrolled. Changes in meibomian gland morphology (meiboscores, gland dropout, and shortening) were evaluated by using meibography equipped in ...

PURPOSE The purpose of this study was to examine the effects an eye movement exercise intervention on cognitive function and prefrontal cortex connectivity in elderly with mild impairment.METHODS Ten older adults impairment participated consisting saccadic movement, pursuit vestibular-ocular vergence for 4 weeks. Cognitive (MoCA-K), reaction time during stroop task, were measured using function...

AIM To evaluate the possible effects of phacoemulsification cataract surgery on ocular hemodynamics. METHODS In this prospective study, intraocular pressure (IOP), pulsatile ocular blood flow (POBF), and ocular pulse amplitude (OPA) were measured pre-operatively (baseline) and at 1 week and 3 weeks postoperation in 52 eyes of 26 patients (mean age 63.15±10.25 years) scheduled for unilateral p...

Received for publication October2005 .................................. Although intraocular pressure (IOP) is closely linked to the pathogenesis of primary open angle glaucoma (POAG) and reduction of IOP slows down the glaucoma damage, 12% of subjunctives with controlled IOP continue to have progressive visual field loss and about 30% of glaucoma patients never experience high IOP. Clinical ex...

The purpose of the study is to determine the most important diagnostic criteria for distinguishing preperimetric glaucoma from perimetric glaucoma on the basis of a comprehensive assessment of structural changes and indicators of ocular blood flow. 90 eyes, including 30 eyes with preperimetric glaucoma, 30 eyes with perimetric glaucoma, and 30 normal eyes were analyzed in the present study. The...
