Purpose: Orbital implant exposures, infections, and extrusions can occur many years following enucleation or evisceration. This study analyzes complication rates following porous orbital implant wrapped with a posterior auricular muscle complex graft (PAMCG).
Methods: This is a retrospective study of patients who underwent orbital implantation following enucleation using this technique between 1992 and 2013.
Purpose: Studies on age-related macular degeneration often use rod-mediated dark adaptation (RMDA) to evaluate macular functional health, studying eyes with cataract and pseudophakic eyes within the same sample. We examine a poorly understood issue-whether rod intercept time (RIT), a measure of RMDA, changes after cataract surgery and intraocular lens (IOL) insertion as compared to RIT before cataract surgery. Cataract may serve as a filter reducing photo-bleach magnitude prior to surgery, biasing RMDA interpretation.

An 84-year-old man presented with a localized, firm, tender mass over the right lacrimal sac. He had a history of acute dacryocystitis in the same eye 6 months before presentation, which resolved with antibiotics followed by uneventful dacryocystorhinostomy. At repeat presentation, the patient underwent orbital imaging and excisional biopsy of the lesion.

Design: Prospective cohort.
Participants: Adults aged ≥60 years were recruited from primary care ophthalmology clinics.
Purpose: Delayed rod-mediated dark adaptation (DA) is characteristic of early age-related macular degeneration (AMD) and also can be observed in some older adults in normal macular health. We examine cross-sectional associations between rod-mediated DA and risk factors for AMD in older adults in normal macular health.
Methods: The sample consisted of adults aged ≥60 years old in normal macular health per grading of fundus photos using an established disease classification system.
Environmental health information resources lack exposure data required to translate molecular insights, elucidate environmental contributions to diseases, and assess human health and ecological risks. We report development of an Exposure Ontology, ExO, designed to address this information gap by facilitating centralization and integration of exposure data. Major concepts were defined and the ontology drafted and evaluated by a working group of exposure scientists and other ontology and database experts.

Cumulative risk assessment is a tool for organizing and analyzing information to examine, characterize, and possibly quantify the combined adverse effects on human health or ecologic resources from multiple environmental stressors.

Purpose: To compare the mobility of wrapped and unwrapped hydroxyapatite orbital implants after enucleation.
Methods: Fifteen consecutive adult patients underwent enucleation with hydroxyapatite implant placement. These patients randomly received either a wrapped or unwrapped implant.
