Anterior uveitis, poliosis, and skin hypopigmentation associated with topical chloramphenicol allergy following ptosis surgery.

The association of uveitis and vitiligo has long been established in specific disease entities: Vogt-Koyanagi-Harada syndrome and sympathetic ophthalmia. We report an unusual case of topical chloramphenicol allergy associated with an anterior uveitis with subsequent poliosis and periocular vitiligo, following anterior approach levator advancement surgery.

Structural mechanisms of trabecular bone loss in man.

The relationship between trabecular thinning and loss of connectedness of the trabecular bone pattern has been studied in iliac crest bone samples from 89 normal subjects in order to determine the structural mechanisms underlying age-related bone loss. Trabecular width and structure were quantitatively assessed using computerized techniques. Highly significant negative correlations were found between the mean trabecular plate thickness and number of free ends/mm2 both in males (r = -0.
