PURPOSE: To clarify in which cases of blow-out fractures ocular motility will naturally recover. DESIGN: A retrospective review of observational cases. METHODS: Involved ocular motility ranges were measured by the Hess screen test at 15 or 30 degrees in 23 nonsurgical blow-out fracture patients without muscle entrapment or strong mechanical ocular restriction and in eight surgical patients with the above. RESULTS: In nonsurgical patients, the eyes moved more than 10 or 20 degrees respectively on a 15- or 30-degree Hess screen test in the early period, whereas in the surgical patients, the eyes did not. No nonsurgical patients had serious ocular motility disturbances; however, natural ocular motility recovery in many patients took more than 4 weeks. CONCLUSIONS: When an involved eye without muscle entrapment or strong mechanical restrictions moves more than 10 or 20 degrees on each Hess chart, natural recovery can be expected.

PURPOSE: To investigate the mechanisms of atopic cataract by immunohistochemically observing protein gene product 9.5 in lens epithelial cells (LECs) of atopic cataracts. SETTING: Departments of Ophthalmology and Anatomy, Shiga University of Medical Science, Shiga, Japan. METHODS: Specimens of anterior capsule obtained from 6 patients with atopic cataract and 8 patients with senile cataract were stained immunohistochemically and examined by light, electron, and confocal microscopy. RESULTS: In the LECs of the atopic cataracts, the arrangement and cell shape were varied. Immunohistochemistry for protein gene product 9.5 demonstrated selective localization, unlike with senile cataracts. This was especially prevalent in the spindle-shaped cells around the central opaque lesion. Protein gene product 9.5 positive cells overlapped with major basic protein positive cells in the atopic cataracts. CONCLUSIONS: The results indicate that the properties of LECs of atopic cataracts are different from those of senile cataracts. Protein gene product 9.5 and major basic protein seem to be concentrated in atopic cataracts.
