Importance: The association between availability of eye care clinicians and visual impairment, a condition presenting with increased morbidity and health care costs, has not been thoroughly studied.
Objective: To examine associations between the geographic distribution of eye care clinicians and visual impairment in California.
Design, Setting, And Participants: This survey-based cross-sectional study included ophthalmologists and optometrists licensed in California in 2018 and 2020 as well as respondents to the 2014 to 2018 American Community Survey (ACS) by California counties and Medical Service Study Areas (MSSAs).
Purpose: To summarize the results of 5 years of vision screening with the University of California, Los Angeles (UCLA) Preschool Vision Program (UPVP).
Design: Retrospective evaluation of a screening program.
Methods: The UPVP performed visual acuity and undilated noncycloplegic refractive screening using an autorefractor on 93,097 children between 2012 and 2017.
Purpose: To report the outcomes of full ophthalmic examination for preschool children in LA County who failed screening with the Retinomax Autorefractor.
Design: Retrospective, cross-sectional study.
Methods: Between August 2012 and May 2013, the University of California Los Angeles (UCLA) preschool vision program screened 11 260 preschool children aged 3-5 years in Los Angeles County using the Retinomax Autorefractor only.
Purpose: To introduce the University of California Los Angeles (UCLA) Preschool Vision Program (UPVP) and describe the utilization pattern and challenges of the first year of implementation.
Methods: The UPVP aims to improve vision in 3- to 5-year-old preschoolers of Los Angeles County. On the first visit, trained personnel use a handheld autorefractometer (Retinomax 3; Righton, Japan) for initial screening and identify those who would benefit from a complete eye examination.
Purpose: To develop and assess the validity of an evaluation tool to assess quantitatively the hydrodissection and phacoemulsification portions of cataract surgery performed by residents.
Design: Case series.
Setting: Jules Stein Eye Institute, Olive View-UCLA Medical Center, and Veterans Administration Medical Center, Los Angeles, California, USA.
Purpose: To investigate the utility of corneal biopsy in the evaluation of infectious keratitis; to compare results of culture and histopathologic examination of the same specimens; to investigate potential factors related to positive biopsy results.
Design: Retrospective, observational case series.
Methods: We reviewed medical records for all patients who underwent corneal biopsy because of infectious keratitis at the Jules Stein Eye Institute from June 1989 through June 2009.
Purpose: To develop and assess the validity of an evaluation tool to quantitatively assess the capsulorhexis portion of cataract surgery performed by residents.
Setting: University of California at Los Angeles (UCLA), Department of Ophthalmology, Jules Stein Eye Institute, Los Angeles, California, USA.
Design: Masked prospective case series.
Objectives: This is a prospective study in an urgent-care ophthalmic setting to investigate contact lens (CL) complications and their association with extended wear (EW).
Methods: Data on CL designs, care system(s), and ocular complications were collected over a 6-month period.
Results: One thousand three hundred and sixty-nine patients presented to the Jules Stein Eye Institute urgent care with symptoms of eye problems.
Purpose: To determine incidence and risk factors for graft failure following penetrating keratoplasty (PK) in eyes with Ahmed valves (AV).
Design: Retrospective, observational cohort study.
Methods: Patients who underwent PK after AV implantation (both performed at our institution through 2004) were studied.
Although the risk of developing contact lens associated microbial keratitis is small, the potential consequences of this condition, such as vision loss, are serious. This paper presents an analysis of the risk factors that have been identified for contact lens induced microbial keratitis, which include extended wear, hypoxia, non-compliance, blepharitis, diabetes mellitus, epithelial trauma, steroid use, therapeutic lens use, tobacco use, and possibly travel to warm climates. By remaining mindful of these risk factors, practitioners can take action and offer advice to patients so as to optimize the safety of contact lens wear.

Design: Experimental animal study.
Methods: Corneas of New Zealand albino rabbits were treated with topical azithromycin (2 mg/ml or 4 mg/ml) or clarithromycin (10 mg/ml).
Purpose: To describe the presentation and management of the first identified case of ocular vaccinia infection associated with the current smallpox vaccination program.
Design: Case report.
Methods: Vaccinia virus was isolated by cell culture of a conjunctival swab.
Purpose: To report a case of severe bilateral deep stromal neovascularization and opacification associated with unmonitored contact lens wear.
Design: Observational case report.
Methods: A 46-year-old woman who had been using hydrogel contact lenses bought on the Internet without a prescription for 5 years was found to have dense, bilateral corneal opacities with deep stromal neovascularization.
Purpose: Infectious endophthalmitis is characterized by neutrophil migration into the eye. The purpose of this study was to determine whether systemic neutrophil depletion mitigates the ocular influx of neutrophils during the early phases of experimental endophthalmitis.
Methods: Endophthalmitis was induced in rats by intravitreal injection of Staphylococcus aureus.
Among the many problems complicating contact lens wear, microbial keratitis is of most concern because of its potential for substantial morbidity. Three decades of basic and clinical research suggest that risk factors include poor care compliance and extended wear through one or multiple sleep cycles. Many believe the latter problem is caused in part or in whole to contact lens-induced hypoxia.

Participants: Because of the highly specific nature of this group of diseases, the 26 invited participants included either international scholars in the field of mucous membrane pemphigoid or experts in cutaneous pharmacology representing the 3 medical disciplines ophthalmology, oral medicine, and dermatology.
