RESUMO
A 35-year-old man was initially seen following the incidental discovery of swollen optic disc in both eyes. Over a subsequent 15-year period, the patient experienced an inexorable loss of vision in both eyes, characterized by normal neuroradiologic findings and the presence of opticocillary shunt vessels on both discs. A craniotomy ultimately demonstrated the presence of bilateral optic nerve sheath meningiomas that appeared to have arisen multifocally.

We studied four patients with anisocoria and the pigmentary dispersion syndrome. In all patients, the larger pupil was on the side of the greater iris transillumination. The amount of anisocoria was between 0.5 and 1.5 mm and was the same in both the light and dark. There was no blepharoptosis, and all pupils dilated normally with cocaine. All of the patients were young men with myopia, and one patient had increased intraocular pressure.

In two patients opticociliary venous shunts occurred in association with pseudotumor cerebri. One patient underwent bilateral optic nerve sheath fenestrations, after which her papilledema resolved, and the opticociliary venous shunts were noted to be markedly decreased in caliber.

This study examined the behaviors of black Head Start children and their mothers around a series of experimental joint reading contexts in their homes. There were 2 specific objectives: (1) to examine the effects of text genre (narrative and expository) and text format (familiar and traditional) on mothers' teaching strategies while interacting with their children around reading tasks, and (2) to examine the effectiveness of mothers' teaching strategies in eliciting children's participation in the joint reading tasks. 13 mother-child dyads were videotaped in their homes while interacting around a series of texts in each genre and format. Results indicated that genre, not format, affected mothers' teaching strategies. Further, mothers adjusted their level of teaching to children's level of task competence. Results are discussed in terms of Vygotsky's notion of the zone of proximal development.
