Acute attacks of glaucoma are usually precipitated by dilation of the pupil by medications or dark environments. Pain is initially restricted to the eye but can become generalized throughout the head. Blurred vision and rainbow lights may result from corneal edema. In severe attacks, patients develop nausea and vomiting. Pilocarpine drops may be used to constrict the pupil and reestablish circulation of aqueous humor.
Surgery remains the definitive choice to treat the condition and prevent recurrence.
At least 1 percent of persons in the population have symptomatic nasal polyps and up to 42 percent may have asymptomatic polyps on careful examination of the middle meatus, middle turbinate and ethmoids. The cause of nasal polyps is unknown, but they may be associated with asthma, cystic fibrosis and aspirin allergy. The most common symptom is nasal obstruction, but rhinorrhea, loss of smell and taste, and respiratory infections are also likely. Polyps are visualized as pale, grapelike structures prolapsing into the nasal cavity from the middle meatus. After one month of treatment, or after symptoms have been controlled, intranasal steroid spray is used for maintenance treatment.
