Brainstem auditory evoked responses during the recovery of Wernicke's disease.

Serial brainstem auditory evoked responses (BAERs) during the acute and recovery phase of Wernicke's disease were studied in two patients. Both morphologic abnormalities and prolongation of absolute and interpeak latencies of wave I through V were noted during the acute and recovery periods. Normalization was found in one patient and incremental improvements in the other. This study suggests that the BAER may provide documental evidence of auditory tracts involvement in Wernicke's disease. The diagnostic value of the BAER is for establishing the presence of brainstem involvement when features of classical triad of Wernicke's disease are absent. This pathologic process may or may not be reversible with thiamine treatment.

Orbital dacryops.

Two patients presented with an enlarging orbital mass that proved to be simple dacryops, a condition in which a cyst arises in the palpebral lobe of the lacrimal gland. The cyst in one patient was lined by one to two layers of relatively flat epithelial cells favoring a lacrimal gland ductal origin. In the second patient, the cyst was lined by a nonkeratinized stratified squamous epithelium with numerous goblet cells consistent with a conjunctival origin.

Nonteratoid medulloepithelioma of the ciliary body.

A 34-month-old girl was treated for anterior uveitis, a superiorly subluxated cataract, rubeosis iridis and secondary glaucoma of the right eye of 3 months duration. She was diagnosed as having medulloepithelioma only after a mass was subsequently identified on the anterior surface of the iris. A low grade malignant nonteratoid medulloepithelioma was found to involve the ciliary surface throughout the circumference of the enucleated right globe. These tumors are generally associated with a good prognosis for survival, but are potentially lethal when they extend extrasclerally.
