Cavernous sinus thrombosis following sinusitis results in all of the following signs except:
Constricted pupil in response to light
Engorgement of retinal veins upon ophthalmoscopic examination
Ptosis of eyelid
Ophthalmoplegia
Ptosis and ophthalmoplegia occur in cavernous sinus thrombosis due to involvement of III and IV and V cranial nerves. Retinal vessels are also engorged but pupils are fixed and dilated,due to involvement of III nerve and sympathetic plexus. Ref Dhingra 5/e,p 214.
