Purpose:The authors of the present study report a case of phthiriasis palpebrarum treated with petrolatum ointment and tea tree oil in a 12-month-old boy. Case summary: A bluish-gray macule and blood clots were found on the central portion of the upper eyelid of a boy who had rubbed his eyelid vigorously 1 week prior. Several 0.5 mm sized brownish-gray nits and 1.6 mm sized lice on the eyelashes were visible and was diagnosed with phthiriasis palpebrarum after light microscopic examination. The nits and lice were gently removed mechanically with the help of a white petrolatum ointment (Vaseline) and the eyelashes were cleaned with 50% tea tree oil. Nits and lice were successfully eradicated without recurrence 10 days after daily treatment with petrolatum ointment and 10% tea tree oil eyelash cleansing.

Purpose:To measure the orbital volume from facial CT scans using a semi-automatic computer program. Methods: Axial and coronal slices of 35 facial CT scans were used to measure the orbital volume. The cross-sectional area was determined from each slice using a semi-automated computer program (MATLAB 2009a

Case Summary: A 74-year-old woman presented to our clinic with decreased visual acuity in both eyes. Such symptoms started 1 month prior to her visit, after sudden onset of left-side motor power weakness and dysphasia. Following the initial symptoms, our patient consecutively experienced worsening dysphagia, ptosis, and lateral gaze limitation. We confirmed the diagnosis as Miller Fischer syndrome with a positive anti-GQ1b antibody serology. She received immunoglobulin treatment for 5 days in other departement. She visited our clinic due to continuing diplopia, decrease of visual acuity and gait disturbance. On initial examination, the corrected visual acuity was 0.5 in both eyes. Ptosis of both eyelids, esodeviation, limitation in ocular movement was noted. The fundoscopic examinations revealed relatively pale optic disc. There was decrease in color vision in both eyes. The visual evoked potential test showed low amplitude and delayed latency in P100 wave in both eyes. Two months after her initial visit to our department her symptoms started to improve, and after 4 months all the initial problems resolved completely and her corrected visual acuity checked out to be 0.8 in both eyes and VEP abnormality was recovered. Conclusions: It is extremely uncommon for Miller Fisher syndrome to involve the optic nerve. We present such a case of a 74-year-old woman whose symptoms improved 4 months after its first attack with treatment.
