The Role of 24-hour Ambulatory Blood Pressure Monitoring in Hypertensive Patients with Normal-tension Glaucoma.

Introduction: Extreme dippers are patients with a nocturnal fall of blood pressure (BP) of more than 20%, dippers have normal diurnal rhythm and decrease of BP of 10-15%, while patients with a nocturnal BP fall of less than 10% are considered to be non-dippers.

Objective: The aim of this study was to compare 24-hour ambulatory BP monitoring results of normal-tension glaucoma (NTG) patients with NTG suspects, as well as to determine whether NTG patients are more prone to daytime/nighttime systemic arterial BP and heart rate oscillations in comparison to NTG suspects.

Methods: This was a prospective, cross-sectional and observational study of 57 hypertensive patients (39 female and 18 male), all examined at the Eye and the Cardiology Clinic, Clinical Center of Serbia in Belgrade, between November 2011 and March 2012.

Optic disc changes between first and final photographs were noted as well as progression identified by HRT topographic change analysis (TCA) and rim area regression line (RARL) Agreement between progression indentified by photography and HRT methods was assessed.

Morning glory syndrome associated with primary open angle glaucoma--case report.

Introduction: Morning glory syndrome (MGS) is a rare congenital optic disc anomaly, first reported in 1970. MGS is a nonprogressive and untreatable condition, which usually occurs as an isolated ocular anomaly, and can be associated with the increased incidence of nonrhegmatogenous retinal detachment, and also with strabismus, afferent pupillary defect, visual field defects, presence of hyaloids artery remnants, ciliary body cyst, congenital cataract, lid hemangioma and preretinal gliosis.

Case Outline: We report a clinical case of MGS associated with primary open angle glaucoma.

Objective: The aim of this study was to evaluate the changes of the hemodynamic parameters in the retrobulbar arterial circulation after decrease of the elevated intraocular pressure (IOP) in women and men with primary open angle glaucoma.

Methods: The study included 60 patients (33 males and 27 females) older than 50 years, with diagnosed and treated primary open angle glaucoma (77 eyes of 39 patients had increased IOP, > 25 mm Hg).

[Comparison of normal tension and high tension glaucoma patients (corrected) according to age and sex].

Introduction: According to the level of intraocular pressure (IOP), open angle glaucoma is divided into high tension glaucoma (HTG) and normal tension glaucoma (NTG).

Objective: To determine if there are differences in the distribution of patients by age and sex between NTG and HTG.

Methods: Our prospective study included 30 patients with NTG and 30 with HTG.

The effect of intraocular pressure on visual field after trabeculectomy in patients with primary open angle glaucoma.

Purpose: To compare the mean intraocular pressure (IOP), peak IOP and percentage reduction in IOP in the first five years following trabeculectomy between the patients with progressed visual field loss and the patients with stable visual fields.

Material And Methods: Thirty-six eyes of 36 patients were followed for five years after their first trabeculectomy with tonometry and automated perimetry (Octopus 500EZ, program G1). The rate of change of the visual field was measured by linear regression analysis of the mean sensitivity value (dB) of each field test versus time (month).

[Influence of initial visual field sensitivity on visual field loss progression in open angle glaucoma].

Introduction: It is important to know the risk factors for visual field defect progression in order to predict the future development of glaucoma.

Objective: To investigate the influence of visual field initial sensitivity on the rate of visual field progression.

Methods: A minimum of five visual fields were performed using computerized perimetry (Octopus) over a mean followup 4-year period (48.

Changes in the retrobulbar arterial circulation after decrease of elevated intraocular pressue in patients with primary open angle glaucoma.

Introduction: An altered perfusion of the optic nerve head has been proposed as a pathogenic factor in glaucoma.

Objective: To evaluate changes of haemodynamic parameters in the retrobulbar arterial circulation after a decrease of elevated intraocular pressure (IOP) in patients with primary open angle glaucoma (POAG).

Methods: Twenty-six patients were examined, 14 men and 12 women, 21 up to 50 years old and 5 below, all with previously diagnosed and treated POAG, and all examined at the Eye Clinic, Clinical Centre of Serbia.

Correlation between ocular pulse amplitude measured by dynamic contour tonometer and colour Doppler flow imaging of the arteric retrobulbar vessels.

Introduction: An altered perfusion of the optic nerve head has been proposed as a pathogenic factor in glaucoma.

Objective: The aim of this study was to evaluate the correlation between ocular pulse amplitude (OPA), measured by Dynamic contour tonometer (DCT) and colour Doppler imaging (CDI) of the arteric retrobulbar vessels.

Methods: Twenty patients older than 50 years were examined, and divided into two equal groups.

Is nail fold capillaroscopy useful in normotensive and primary open angle glaucoma? A pilot study.

Purpose: Vascular dysregulation is deemed a significant risk factor in glaucoma occurrence and progression. Capillaroscopy of the blood vessels on the finger nail-fold is a method that can provide information regarding the state of the vascular system at the capillary level. The aim of this pilot study was to determine whether there are significant differences in the morphological characteristics of the peripheral blood vessels in normotensive glaucoma and primary open angle glaucoma.

Simultaneous injuries to both eyes in traffic accidents.

Background: In traffic accidents, eye injuries occur as isolated or with polytrauma. They may involve just one eye, but simultaneous injuries to both eyes do happen occasionally. The aim of our paper was to reveal the risk factors, in an effort to reduce the number of such accidents and to prevent bilateral ocular damage.

Correlation between central corneal thickness and intraocular pressure in various age groups.

Introduction: The Pascal Dynamic Contour Tonometer (DCT) is an ophthalmic investigational device which directly calculates the dynamic pulsatile fluctuations in intraocular pressure (IOP) using a piezoelectric pressure sensor embedded in the devices tip.

Objective: The aim of this study was to compare IOP results obtained with Goldmann applanation tonometer (GAT), and their correlation with central corneal thickness (CCT) in patients of various age groups.

Methods: We studied 37 patients (17 male and 20 female), divided into three age groups: younger than 40 years; 40-60 years old, and older than 60 years.

[Unilatelaral iris plateau syndrome after the use of ecstasy].

Background: Courmon street name for 3,4-Methylenedioxymethamphetamine (MDMA) is ecstasy. This widely abused "recreational" drug causes both an increased release of monoamine neurotransmitters, including serotonine and dopamine, and an increased reuptake inhibition of serotonin. As a consequence, mydriasis and increased intraocular pressure (IOP) in predisposed patients occur.

[Contribution and significance of Heidelberg Retinal Tomography II in diagnostics of ocular hypertension and its conversion into primary open-angle glaucoma].

Background/aim: A term "ocular hypertension" is used when IOP is found to be >21 mmHg on two consecutive occasions, in the absence of detectable glaucomatous damage. The aim of this study was to determine the significance and contribution of Heidelberg Retinal Tomography II (HRT II) results that show very early, subtle changes in retinal neurofibre layers (RNFL) in the optic nerve head that are specific for glaucoma itself (the loss of neuroretinal rim area and an increase of Cup/Disc ratio), but are not possible to register by an ophthalmoscope. Also, when the results of the functional tests remain unchanged, that confirms the conversion of ocular hypertension into glaucoma.
