Sinus Infection Complications Affecting The Brain

Blurry vision, brain fog, and increased ocular pressure, due to Intracranial Hypertension

An even more rare, and more serious, complication of sinus infection would be the infection spreading to the brain. The brain is protected by the blood-brain barrier, whose function is to separate circulating blood from the brain and the fluid of the central nervous system. Its very difficult for sinus infection to be able to cross this border, despite the proximity of the sinuses to the brain.

The blood-brain barrier is semipermeable, however, and it is possible on rare occasions for an infection to get through from the sinuses to the brain. If a sinus infection spreads to the brain, it can be a life-threatening condition, leading to swelling of the brain, meningitis, or brain abscess.

Symptoms might include:

  • Severe headache, and
  • Swelling in the face.

Most of these symptoms would require an emergency visit to the doctor, even without an association with a sinus infection.

Altered Cervical Joint Position And Movement Sense Static And Dynamic Balance And Ocular Mobility And Coordination Should Become An Essential Part Of The Routine Assessment Of Those With Traumatic Neck Pain

Dr. Julia Treleaven, Ph.D., is a member of the Neck Pain and Whiplash Research Group, Division of Physiotherapy, School of Health and Rehabilitation Sciences, University of Queensland, St Lucia, Australia. She has also written numerous papers on the problems of impaired function in the cervical neck. The paper cited at the top of this article is one that she co-authored.

In the July 2017 edition of The Journal of Orthopaedic and Sports Physical Therapyshe wrote:

There is considerable evidence to support the importance of cervical afferent dysfunction in the development of dizziness, unsteadiness, visual disturbances, altered balance, and altered eye and head movement control following neck trauma, especially in those with persistent symptoms.

However, there are other possible causes for these symptoms, and secondary adaptive changes should also be considered in the differential diagnosis.

Understanding the nature of these symptoms and differential diagnoses of their potential origin is important for rehabilitation.

How Can Sinusitis Affect Eyesight

The paranasal sinuses are found in the bones of the face maxillary, sphenoid, ethmoid, and frontal and, therefore, an infection or inflammation that affects this area can affect the eyes. When this happens, medical attention is required as soon as possible. Typically, those who suffer from sinusitis and describe vision problems complain of blurred or unclear vision in one eye, difficulty seeing clearly from afar, bulging eyes, and even diplopia, commonly known as double eyesight.

Since the ethmoid sinuses are adjacent to the tear ducts, ethmoid sinusitis accounts for the majority of cases of eye-related problems. One of the complications to watch out for is an orbital infection or an eye socket infection, which causes swelling and drooping of the eyelid and leads to eye movement loss.

In rare cases, pressure on the optic nerve can lead to vision loss. These problems can go away once sinusitis has been properly treated, but damage can sometimes be irreversible.

In short, if you suffer from sinusitis and notice any alteration in your vision, see your doctor as soon as possible.

What Causes Astigmatism

Astigmatism develops when either the cornea or lens of the eye changes shape.

The eyeball should be shaped like a sphere. An astigmatism causes the eye to be the shape of an oval or football. This change can happen naturally as you get older. You can also be born with astigmatism.

When the cornea or lens is not evenly curved, light entering the eye bends the wrong way. Normally, light enters the eye and hits the retina . The retina converts light signals into electrical signals and then passes these signals to the brain so you can see.

If you have a refractive error, like an astigmatism, the light hitting your retina is bent out of shape. Your retina passes on these distorted light signals to your brain. So you see images that look blurry or distorted.
