Role of Transthoracic Echocardiography in the Evaluation of Patients with Retinal Vein Occlusion

   Introduction: Retinal vein occlusion  is a common vascular disorder disrupting vision. Two basic types of RVO are branch retinal vein occlusion and central retinal vein occlusion (CRVO).  Retinal vein occlusion is a multifactor process including systemic illness and local retinal factors.RVO may be associated with atherosclerotic risk factors. We analyzed the role of 2 dimensional transthor...

The relationship between impaired retinal vascular reactivity and renal function in patients with degenerative vascular disease.

In hypertension and diabetes retinal vascular changes which are evident on fundiscopic examination are usually accompanied by renal vascular changes which are evident on microscopic examination. It has been found that the retinal vessels of most patients with hypertension or diabetes fail to constrict normally when the blood oxygen tension is elevated. This investigation evaluates the clinical ...

Evaluation of Optical Coherence Tomography Angiography Findings in Patients with Branch Retinal Vein Occlusion

Purpose: To analyze the correlation of optical coherence tomography angiography (OCTA) findings with visual acuity (VA) in patients with branch retinal vein occlusion (BRVO). Methods: This cross-sectional study was performed on 20 eyes of 20 patients with unilateral BRVO involving the macula referred to the ophthalmology clinic of Rassoul Akram Hospital. OCTA imaging was conducted for all patie...

The reactivity of the capillary bed of the nailfold to circulating epinephrine and nor-epinephrine in patients with normal blood pressure and with essential hypertension.

Several studies have attempted to determine whether the vascular system of patients with essential hypertension is hyper-reactive to epinephrine. In these studies vascular reactivity was judged solely by the increase in arterial blood pressure following the parenteral administration of this pressor substance. Some investigators believed that this method indicated vascular hyperreactivity to epi...

Quantification of retinal capillary density and flow velocity in patients with essential hypertension.

Arterial hypertension is known to be an important risk factor for cerebral and cardiovascular disease. Previous studies in rats have demonstrated that changes in both capillary density and vessel diameter may contribute to increased vascular resistance in hypertension. In vivo studies of human subjects with essential hypertension revealed a reduction in the number of arterioles in the skin and ...

Hypertension Secondary to PHPT: Cause or Coincidence?

Primary hyperparathyroidism (PHPT) may be associated with arterial hypertension. The underlying mechanisms are not fully understood and reversibility by parathyroid surgery is controversial. This study aimed to characterize pressor hormones, vascular reactivity to norepinephrine, and cytosolic-free calcium in platelets in 15 hypertensive patients with hypercalcaemic PHPT before and after succes...
