The Determination of Type 2 Diabetes Mellitus's Impact on the Density of Retinal Blood Vessels and the Choriocapillaris: Optical Coherence Tomography Angiography Study.

Optical coherence tomography angiography (OCTA) was used to analyze the alterations in the density of retinal blood vessels and the choriocapillaris (VD) in patients suffering from type 2 diabetes mellitus (T2DM). One hundred sixty-six eyes of 83 patients (43 of whom were men and 40 women, with a mean age of 58.59 ± 14.

Optical coherence tomography in the evaluation of structural changes in primary open-angle glaucoma with and without elevated intraocular pressure.

Background/aim: Glaucoma is a progressive optic neuropathy characterized by damage of the retinal ganglion cells and their axons and glial cells. The aim of this study was to evaluate the differences and connections between changes in the visual field and the thickness of the peripapillary retinal nerve fiber layer (RNFL), using optical coherence tomography (OCT) in patients with primary open-angle glaucoma with normal and elevated intraocular pressure (IOP).

Methods: This prospective study included 38 patients (38 eyes) with primary open-angle glaucoma with normal intraocular pressure (NTG) and 50 patients (50 eyes) with primary open-angle glaucoma with elevated intraocular pressure (HTG), paired by the same degree of structural glaucomatous changes in the optic nerve head and by age.

[Effect of a tight necktie on intraocular pressure].

Introduction: Any factor causing constriction of the neck may lead to an increase in intraocular pressure. A tight necktie may result in increasing intraocular pressure, which could lead to an erroneous diagnosis and treatment of ocular hypertension or even glaucoma. This study was aimed at evaluating the effect of a tight necktie on intraocular pressure measurement using Goldmann applanation tonometry.

[Therapeutical approach to dry eye syndrome].

Introduction: Dry eye disease or dysfunctional tear syndrome is among the most frequently established diagnoses in ophthalmology. It can be defined as a disorder of the tear film resulting in changes in the ocular surface.

Mechanisms In Development Of Dry Eye Disease: There are many factors causing dry eye and they, can be related to deficiency in any of the components of the tear film.

[Ocular pseudoexfoliation syndrome].

Introduction: This study was aimed at providing an update on most recent developments regarding ocular and systemic manifestations and complications, clinical diagnosis and management, and molecular patophysiology of pseudoexfoliation syndrome.

Method: Review of recent literature and own clinical and laboratory studies.

Results: Pseudoexfoliation syndrome is an age-related disease in which abnormal fibrillar extracellular material is produced and accumulated in many ocular tissues.

Ocular manifestation of rheumatoid arthritis-different forms and frequency.

Rheumatoid arthritis (RA) is a systemic inflammatory disease associated with a number of extra-articular organ manifestations. Ocular manifestations involved with RA are keratoconjunctivitis sicca, episcleritis, scleritis , corneal changes, and retinal vasculitus. The etiopathogenesis of this autoimmune disorder is still unknown.

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.
