Purpose
To describe a case of acute angle-closure glaucoma secondary to intermittent mydriasis related to Pourfour du Petit Syndrome caused by tracheal deviation.
Materials and methods
A 70-year-old Caucasian woman visited the Emergency Room of the University Eye Clinic complaining of blurring of vision and difficulty to move superior eyelid in her right eye. Examination revealed reactive mydriasis, and upper lid retraction on the right side. The rest of the ophthalmological examination was normal, and a cranial computed tomography (CT) did not identify any abnormalities. A cervical CT showed the presence of an accentuated lateral right convex deviation of the trachea, attributable to a fibrothorax. A right Pourfour du Petit syndrome was suspected. Although the mydriasis had in the meantime vanished, the patient was admitted to the Neurological Clinic.
Results
Five days later she suffered acute pain in her right eye. Ophthalmological examination of the right eye revealed conjunctival hyperemia, marked corneal edema, reduced depth of anterior chamber, permanent mydriasis. As assessed by Goldmann applanation tonometry, intraocular pressure (IOP) was 48 mm Hg. Fundus examination was normal in both eyes. Gonioscopy revealed angle closure in all quadrants. Slit lamp examination of the contralateral eye was normal; IOP was 10 mm Hg. After hypotensive medical therapy, iridotomy with YAG laser was performed. Thereafter, IOP stabilized at 12 mm Hg.
Conclusions
This is the first report in the literature of a case of acute angle-closure glaucoma secondary to mydriasis related to Pourfour du Petit Syndrome caused by tracheal deviation.
