Why Sinusitis Affects Your Vision

Author: Adam Bradley

Sinusitis and vision problems can be very much related to one another.  Many people often find their vision is impeded every time their sinus flares up. Watery eyes, blurred vision, and frequent dull eye pain are all associated with sinusitis. Bacterial sinusitis accounts for more than 15% of all sinus infections and sinusitis vision problems. Depending on the sinus that is infected, multiple symptoms may occur. The main reason why people experience blurred vision is that all the four sinus regions are located close to the eye. The maxillary sinus is located in the cheek, the ethmoid sinus between the eyes and nose, the sphenoid sinus behind the ethmoid sinus, and the frontal sinus is located in the forehead above the eyes.

A sinus infection may occur in any or all of the sinus regions. Vision is most likely to be impaired when the infection is in the ethmoid or sphenoid sinus regions. Blurred, and in some cases, double vision are common in these cases. However, the symptoms do not last for very long. In rare cases of ethmoid sinusitis, the pressure exerted on the optic nerve causes a patient to lose eye movement. In other cases, an abscess forms around the eyes due to prolong sinus infection, leading to permanent eye damage without timely medical intervention.

In young males with sinusitis, vision is affected due to the inflammation of the frontal and ethmoid sinuses, in a condition known as osteomyelitis. The inflammation may spread to the inner eye socket and occurs mainly in the frontal sinus region above the eyes. However, this is a rare phenomenon. Common symptoms of osteomyelitis include watering of the eyes, squinting, and severe pain. In a bacterial infection that causes ethmoid sinusitis vision can also be impaired and is accompanied by severe pain in the midline of the face. In chronic cases an orbital infection may occur, which spreads to the cavernous venous sinuses next to the pituitary glands causing an abscess or meningitis. Blood clots may also occur in those suffering from ethmoid and frontal sinus infections. The most common symptom is dilation of the pupils. The blood clot travels to the venous structures around the eye thereby causing impaired vision. However, these symptoms are rare and occur only in chronic cases.

With infections caused by sinusitis, vision is affected mainly due to the drainage of mucus being blocked. The nasolacrimal duct that is right next to the entries sinus areas get blocked due to the inflamed sinus leading to excessive water and moisture in the eyes and subsequent sinusitis vision problems.

The nasal saline irrigation technique with the use of a Neti pot is among the best ways to treat sinusitis vision problems. This therapy involves the use of a salt and water solution to flush out the nasal cavity. The Neti pot is a ceramic pot that has been in use in ayurvedic and yoga as a form of natural medication.  Several ear, nose, and throat surgeons recommend nasal irrigation to clear the nasal passage. This helps to thin the mucus and flush it out of the nasal passages.  The cilia, which are tiny hair-like structures that line the nasal and sinus cavities wave back and forth, pushing the mucus back into the throat or to the nose so that it can be blown out.

It is advisable to seek the help of a medical professional in case of any sinusitis vision problems.

    Can sinus pressure cause blurred vision in one eye?
    I’ve had a bunch of sinus pressure lately. I’ve been having random sinus headaches in my left temple, and for the past two days those headaches have been accompanied by blurred vision in the same eye. I’ve had sinus issues most of my life and never experianced this before. Even after my headache goes away, the blurred vision remains.

    I don’t have any health insurance, so I’m mainly wanting to know if this is normal as a symptom of sinuses or not.

    I have sometimes blurred eye vision and after few minutes I have severe headache above my eyes .?
    I have sometimes blurred eye vision and then followed by the severe headache next to my eyes and when headache starts my vision become clear. Although blurred vision is for 10 to 15 min headache following last for one to two days. This specially happens if i am faced with bright lights or after waking up in the morning. Some doctor suggested me not to use pillows and stopped that but still having this problem.

      could just be migraine or amaurosis fugax. so get your cholesterol or lipid profile done at a clinic and if the levels are high, get a sonogram study of your carotids to rule out AF….can be a presursor to stroke. so see a neurologist.

    What can cause blurred vision in one eye?
    I sometimes (not any time recent) have blurred vision in a single part of a single eye. Usually the right eye and its usually only the upper right hand corner of that eye but its impossible to see anything in that section (about half the eye). I sometimes feel a slight headache with them, but not always and it goes away after about 10-30 min. I was just thinking about it and maybe someone out there knew what it was. It doesnt seem like a serious problem im just curious.

    i wish to know treatment for one eye blurred vision?
    any lasik or laser therapy avialble to correct blurred vision in an eye ?

    • Baby says:

      It really depends on what is causing the blurred vision in that eye. If it is caused by an uncorrected refractive error, then yes laser treatment could help to correct it. But if it is caused by pathology such as a retinal detachment then no laser treatment will be of not help.

      You need to go to see an optician first to find out the cause of the blurred vision

    Can Gestational Diabetes affect only one eye with blurred vision?
    I just had my 1 hour GD testing done last week & it came back as 171 when it should be 140. I have to go back and do a 3 hr glucose test to confirm GD. Now I’m starting to put together why I’m always thirsty and why my son is measuring pretty big. My question is can you have blurred vision in only ONE eye as a symptom of GD? Also, if you have failed your 1 hr GD test…what was your numbers? and did you fail the 3 hour one?

    • Skatin' says:

      Yes, blurred vision can be a symptom of GD and it doesn’t matter if it’s one eye or both. However, sometimes vision changes in pregnancy even for people without GD, so just make sure you tell your doctor about it.

      Many people fail the first but pass the second test. They will be looking to see if your high sugar can fall down below a certain benchmark by the 2nd and 3rd hour. Honestly, a 171 isn’t too promising, that is quite high. So even if you do pass the 2nd test you should adjust your eating to help with that sugar spike.
