Dacryocystographic examination does not identify early seventh nerve failure in leprosy patients.

Dacryocystographic examination was performed in two groups of patients: patients having leprosy and those not having leprosy, in order to look for early failure of the facial nerve. The results of this study show that this kind of examination does not improve diagnosis of leprosy.

Clinical ocular study in leprosy patients at a sanitary dermatological hospital in Brazil.

This study is based upon the observation f 363 leprosy patients having different types of the disease. At the time of the examination, we did not have any previous knowledge about the type of leprosy the patients were having. Thus, the eye examination was done without the knowledge of clinical diagnosis. The ocular examination protocol covered the following: visual activity, facial muscle function, eyebrows, eyelashes, lacrimal system, pupil, eye motility, corneal sensitivity, Schirmir's test and study of the anterior segment of the ocular bulb with a slit-lamp. The study patients included 275 cases of lepromatous leprosy, 57 tuberculoid, 29 indeterminate and two dimorphous cases. The age of the patients ranged between 18 and 82 years, and 229 of them were males. Among those patients, 183 were whites, 23 were black and 157 were mulatto.
