In short, these eye drops may be fine to use temporarily, but over time they really prevent your eyes from naturally recovering from whatever is causing the irritation in the first place. Clamping down on those vessels by using a vasoconstrictor counteracts the body’s efforts to repair the problem. This increase in blood flow is trying to help repair whatever irritation is affecting the surface of the eye. The problem is that these sympathomimetics work by a process called vasoconstriction (or artificially clamping down the superficial blood vessels on the eye surface.) Blood vessels on the eye surface often dilate in response to irritation of the eye surface. Both of these drugs are in a category called sympathomimetics,” said Dr. “Visine, Clear Eyes, B&L advanced redness relief, and several other generic versions of this redness relief drop most commonly contain either the active ingredient Tetrahydrozoline or Naphazoline. But what are the ingredients in these drops? And how often should these drops be used without consulting your Eye Associates Physician? Sydney L Tyson, MD, MPH (President and Medical Director of Eye Associates) sends a public service announcement to local communities as his practice has recently been seeing many cases of patients abusing these over-the-counter medications. Signs & Symptoms.While suffering from red, itching, and/or irritated eyes, many of us never hesitate to reach for “Redness Relief Eye Drops.” These drops (the most popular brands being Visine, Clear Eyes, B&L advanced redness relief) are known for temporary relief of minor eye redness or discomfort caused by minor irritants.

This may cause a sudden emergency or even death. Disruption of vital functions: When brain tumors affect the brainstem, they can interfere with breathing, heartbeat, and blood pressure, causing sudden, dangerous changes in these vital functions.Sometimes, the ventricular obstruction cannot be relieved, so fluid must be removed often, a ventriculoperitoneal shunt must be placed. When this occurs, intracranial pressure increases, and symptoms of confusion, vision impairment, and loss of consciousness arise. Hydrocephalus: Often, a brain tumor obstructs the flow of fluid in the ventricles, the spaces where fluid flows.Herniation can cause dilated pupils, rapid breathing, an irregular heartbeat, and may cause death very quickly if not urgently treated. As brain tissue is physically squeezed, it can lose function or be pushed down toward or into the upper spinal cord. Increased intracranial pressure: Because the skull is an enclosed, inflexible space, a growing brain tumor can lead to pressure on other areas of the brain.
