Clinical analysis of exophthalmos caused by brain-related diseases / 中华实验眼科杂志

ABSTRACT

Background Exophthalmos caused by brain-related diseases will result in the serious outcome if treated improperly.It will be helpful for the diagnosis of the disease correctly when signs and symptoms are taken into consideration.Objective This study was to analyze the cause and clinical manifestations of exophthalmos due to brain-related diseases.Methods The elinical data from 38 patients with exophthalmos caused by brain-related diseases was collected and analyzed retrospectively.The sex,age,cause,exophthalmos range,symptom and sign of patients were considered. Results The gender of 38 patients was 21 males(55.26％)and 17 females(44.74％),aged from 16 to 71 years old with the average age 37.21.Four types of brain-related diseases were associated with the exophthalmos of eyeballs,including benign tumor 65.79％(25/38)containing the meningioma 60.53％(23/38),chordoma 5.26％(2/38)；malignant tumor 5.26％(2/38)containing the malignant meningioma 2.63％(1/38),choroid tong one cases of papillary carcinoma 2.63％(1/38)；carotid-cavernous fistula 26.32％(10/38)；meningoencephalocele 2.63％(1/38).Exophthaimos ranged from 18 to 35 mm in the patients with the average value of 22.17 mm.In all of the 38 patients,the right eyes were 36.84％(14/38),and left eyes were 55.26％(14/38)and bilateral eyes 7.89％(3/38).Accompanying signs and symptoms of meningioma included long-term headache (65.22％),nausea and vomiting(21.74％).declined vision(17.39％),elevated intraocular pressure,visual field shrink and loss,etc..Accompanying signs and symptoms of carotid cavernous fistula were loss of vision,pulsatile exophthalmos,noise over the orbit,ocular limitation of movement,eyelid edema(80％),bulbar conjunctival congestion,episodes of eyelid,diplopia(80％),headache(60％). Conclusion Some brain diseases are often accompanied by exophthalmos.Exophthaimos can provide useful clues to the diagnosis of brain diseases.
