Purpose: To determine the ocular consequences of a dominant-negative mutation in the p85α subunit of phosphatidylinositol 3-kinase (PIK3R1) using a knock-in mouse model of SHORT syndrome, a syndrome associated with short stature, lipodystrophy, diabetes, and Rieger anomaly in humans. Methods: We investigated knock-in mice heterozygous for the SHORT syndrome mutation changing arginine 649 to tryptophan in p85α (PIK3R1) using physical examination, optical coherence tomography (OCT), tonometry, and histopathologic sections from paraffin-embedded eyes, and compared the findings to similar investigations in two human subjects with SHORT syndrome heterozygous for the same mutation...

Acute ocular trauma accounts for a substantial number of emergency department visits in the USA, and represents a significant source of disability to patients; however, the orbits remain a potential blind spot for radiologists. The goal of this article is to review the relevant anatomy of the orbit and imaging findings associated with commonly encountered acute ocular traumatic pathology, while highlighting the salient information which should be reported to the ordering clinician. Topics discussed include trauma to the anterior and posterior chamber, lens dislocations, intraocular foreign bodies, and open and contained globe injuries...

A 68-year-old woman presented with infectious crystalline keratopathy 4 months after she underwent a combined phacoemulsification and Descemet's stripping endothelial keratoplasty for Fuch's endothelial dystrophy in her left eye. After 5 months of topical moxifloxacin 1%, the infiltrate responded well but had not completely resolved, with the resulting endothelial failure requiring a penetrating keratoplasty 9 months after the initial operation. Microbiology identified Enterococcus faecalis with the histopathology demonstrating bacterial colonies within the graft interface...

PURPOSE: We describe the clinicopathological and ultrastructural features of an opaque single-piece hydrophilic acrylic intraocular lens (IOL) explanted from a patient. METHOD: The main outcome of this report is the documentation of calcium deposits confirmed by surface analysis. The decrease in visual acuity was due to the opacification of the IOL. The opacification involved both the optic plate and the haptics. RESULTS: The analysis at the scansion electron microscope revealed that the opacity was caused by the deposition of calcium and phosphate within the lens optic and haptics...

INTRODUCTION: Intraocular pressure (IOP) lowering surgery in congenital aniridia glaucoma (CAG) can be complicated by dysgenesis of the limbal region, anterior chamber angle, iris and lens. METHODS: The anterior segments of 23 eyes (17 patients) with congenital aniridia were investigated under general anesthesia using ultrasound biomicroscopy (UBM). The structures of the anterior segment were examined: distance of ciliary body processes from the anterior chamber angle and positioning of Schlemm's canal...

BACKGROUND: The treatment of idiopathic full-thickness macular holes involves surgery to close the hole. Some surgeons advise patients to adopt a face-down position to increase the likelihood of successful macular hole closure. However, patients often find the face-down positioning arduous. There is a lack of conclusive evidence that face-down positioning improves the outcome. The 'Positioning In Macular hole Surgery' (PIMS) trial will assess whether advice to position face-down after surgery improves the surgical success rate for the closure of large (≥400 μm) macular holes...

Presbyopia-treating intraocular lenses (IOLs) are now widely available and offer high predictability at all distances, better visual outcomes, and high patient satisfaction. In most patients, the same multifocal IOL is implanted bilaterally. In certain circumstances, such as during complex surgeries, it is important to be prepared with a backup plan to maintain surgical expectations. We report 3 patients who had femtosecond laser-assisted cataract surgeries in both eyes. The complicated eye had implantation of a bifocal IOL and the fellow eye of a trifocal IOL...
