The cloudiy vision could be "Fuch's Dystrophy." Fuch's is not life threatening. It causes cloudiness of the cornea. Mosrly in the mornings and improves as the day goes on, I have it. Some times it does not improve that much. Look this up on the intrernet, because there is more information on this than I can type right now. Also go to see an "Opthalmologist" or a "Cornea" specialist not an Optrometrist. Mine was discovered during an exam. Make sure you ask them to check for this.
Hi there!
The swollen gland could be related to the sinus infection; while the cloudy vision is unlikely to be related and would require an evaluation by an ophthalmologist to consider issues such as refractive errors, infections, increased eye pressure etc. This does not sound like cancer/ terminal illness. If the eye ointment doesn’t seem to help you may consider a review with his treating doctor.
Hope this is helpful.
Take care!
