Menda and colleagues describe a technique for shortening a long clear corneal incision that may avoid the pitfalls of an incision that is too long.
Wallace et al compare Early Treatment Diabetic Retinopathy Study visual acuity outcome with retinal structural outcome at the 6-year follow-up of infants randomized in the Early Treatment for Retinopathy of Prematurity study, which previously reported reduced rates of poor functional and structural outcomes after early treatment of high-risk eyes with prethreshold retinopathy of prematurity.
Scott and coworkers compared baseline characteristics, changes in visual acuity and center point thickness, safety outcomes, and number of treatments and treatment response of participants with HRVO vs BRVO or CRVO in the SCORE Study. Eyes were randomized to standard care, 1 mg intravitreal triamcinolone, or 4 mg intravitreal triamcinolone.
The Pediatric Eye Disease Investigator Group conducted a prospective study to determine the most cost-effective approach for treatment of nasolacrimal duct obstruction in infants, comparing immediate probing in the office setting vs 6 months of observation with the possible need for surgery to be performed in a surgical facility with the infant under general anesthesia.
Mansouri and coauthors examine the safety, tolerability, and reproducibility of intraocular pressure patterns during repeated continuous 24-hour intraocular pressure monitoring with a contact lens sensor.
De Moraes et al for the Ocular Hypertension Treatment Study Group compare rates of visual field change in ocular hypertensive eyes with and without optic disc hemorrhage.
Mukkamala and colleagues described optical coherence tomographic (OCT) findings of layered hyperreflective bands beneath the retinal pigment epithelium (RPE), the so-called onion sign, believed to represent lipid within a vascularized pigment epithelial detachment. The study involved 22 eyes of 20 patients with sub-RPE hyperreflective bands.
In an observational cross-sectional study, Scholl and coauthors characterize the phenotype of a white patient with occult macular dystrophy and her clinically unaffected family members and determine whether similar mutations were present in the RP1L1 gene in this family.
Binenbaum and colleagues attempt to develop a birth weight, gestational age, and postnatal–weight-gain retinopathy of prematurity prediction model in a cohort of 524 infants meeting current screening guidelines. As a simple logistic equation, it can be calculated by hand or represented as a nomogram for easy clinical use.
A retrospective cohort with thyroid-associated orbitopathy was used by Savar and colleagues to show photographic evidence of eyebrow tissue expansion and to demonstrate consistency in grading using of standardized photographs.
Saleh et al evaluate kinematic analysis as a technique to elucidate patterns of movement in assessing surgical skills.
Lewallen and colleagues obtained raw data on age-specific cataract prevalence from standardized population-based surveys to estimate and compare the incidence of operable cataract and the desired cataract surgery rates required to eliminate cataract-related visual impairment in several Latin American settings. Dr Sommer provides commentary in an accompanying editorial.
To determine whether racial disparities exist in the use of ancillary testing to evaluate individuals with open-angle glaucoma (OAG), Stein and colleagues identified all enrollees aged 40 years and older in a large US managed care network with retinal or optic nerve conditions that could warrant the use of ancillary testing. Among the 797 879 eligible enrollees, 149 018 individuals had OAG.
Emily Dickinson and Dr Williams met during the time of the Civil War, when Emily consulted him about her ophthalmic disorder. No records of the diagnosis survive. Iritis, exotropia, or psychiatric problems are the most frequent diagnoses offered to explain her difficulties. Blanchard offers an additional possibility that Dr Williams likely considered (ie, hysterical hyperaesthesia of the retina).
