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.

To evaluate the optical performance of toric intraocular lenses (IOLs) after decentration and with different pupil diameters, but with the IOL astigmatic axis aligned.

The objective of this paper is to investigate the pattern of abnormalities and establish the diagnostic power of multifocal objective pupil perimetry (mfPOP) in multiple sclerosis (MS).

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.

To evaluate the safety and efficacy of combined 23-gauge transconjunctival pars plana vitrectomy and scleral fixation of intraocular lens (IOL) without conjunctival dissection.

To evaluate the efficacy and safety of the excimer laser correction of the residual refractive errors after cataract extraction with intraocular lens (IOL) implantation in uncommon cases.

To report the long-term results of temporary piggyback IOL implantation in congenital cataract and to compare the clinical outcomes of temporary piggyback IOL with those of single IOL implantation.

To describe a patient with flap complications after LASIK who was subsequently treated using phototherapeutic keratectomy (PTK) and an autologous lenticule transplant obtained via small incision lenticule extraction (SMILE).

To simulate the optical performance of three presbyopia-correcting intraocular lenses (IOLs) implanted in eyes with previous laser refractive surgery.
