Infrared pupillometry was introduced in 1962 but portable instruments that use this technology have only recently become available in the hospital setting. Questions surrounding the accuracy of these instruments have been addressed by documenting the inter-observer agreement on pupillary measurements and also by comparisons with standard pen-light examinations. The following commentary summarizes the development of these devices and provides a wider perspective on how the pupil and its reflexes might be used in providing care for patients with critical illness.

Improvement in surgical devices and intraocular lenses has made modern cataract surgery a safe procedure with decreasing complication rates. Intraocular lens dislocation is a serious complication after cataract surgery. Although most dislocations occur during the first week postoperative period, late intraocular lens dislocation occurring 3 months or later post-surgery has been reported with increasing frequency in recent years as a result of progressive zonular dehiscence. We report the clinical features, management and outcomes of five cases of late in-bag dislocation of intraocular lens in patients with underlying uveitis. This is a retrospective case series and literature review.

Purpose To determine the incidence of ophthalmologic disorders in children with autism and related disorders. Design Retrospective chart review. Four hundred and seven children diagnosed with autism or a related disorder between 1998 and 2006. one hundred and fifty-four of these children completed a comprehensive ophthalmology exam by a pediatric ophthalmologist. Results Ophthalmologic pathology was found in 40% of patients with autism or a related disorder with 29% having significant refractive errors, 21% demonstrating strabismus, and 10% having amblyopia. Conclusions Children with autism or a related disorder will frequently have an ophthalmologic abnormality. Since cooperation with vision screening is understandably limited in these children, a comprehensive eye examination by a pediatric ophthalmologist is recommended for all such children.
