Purpose: This study describes the implementation of an electronic medical record (EMR)-based initiative aimed at reducing the number of patients with glaucoma-related diagnoses lost to follow-up (LTF) and reviews its short-term outcomes.

Design: Retrospective, comparative case series.

Participants: Patients with glaucoma-related diagnoses seen 1 year prior at the Lahey Medical Center and who had not returned within the 6-month period between January 1, 2020, and June 30, 2020, which spanned the outbreak of the Coronavirus Disease 2019 (COVID-19) pandemic in the United States.

Article Synopsis
  • The study aims to assess how intraocular pressure (IOP) changes when patients with treatment-resistant neovascular age-related macular degeneration switch from other drugs to intravitreal aflibercept (IVA), focusing on those with and without glaucoma.
  • A total of 62 eyes from 58 patients were analyzed retrospectively, observing IOP before and after switching treatments, especially comparing those with glaucoma-related diagnoses to those without.
  • Results showed that while IOP remained stable during other treatments, those with glaucoma had a notable rise in IOP before switching, but IOP decreased significantly after transitioning to IVA for both groups.

Purpose: This study assessed the completeness of clinical information provided by ophthalmological and optometric referrals to glaucoma specialists consulting for open-angle glaucoma (OAG).

Methods: A retrospective, cross-sectional study of 72 internal referrals for evaluation of OAG in a multispecialty group practice was performed. The quality of the referral was assessed based on: (1) the completeness of the clinical triad of intraocular pressure measurement, visual field (VF), and cup-to-disk ratio for each eye; (2) the availability of the data necessary to calculate an ocular hypertension treatment study (OHTS) score; and (3) the presence of retinal nerve fiber layer (RNFL) imaging by mean of optical coherence tomography.

Precis: Evaluation of nonmydriatic fundus photographs captured with a low-cost, smartphone-based camera facilitated remote screening of patients for enlarged optic nerve cup-to-disc ratio in the Independent Nation of Samoa, an underserved setting with one full-time ophthalmologist in the entire country.

Purpose: To investigate factors that impact inter-rater agreement of glaucoma suspect optic disc status using a low-cost, handheld nonmydriatic fundus camera.

Methods: Color fundus photographs were obtained using the PanOptic iExaminer attached to an iPhone 6S by a lay examiner on 206 participants in the Independent Nation of Samoa.

Purpose: To study the extent to which patients with primary open-angle glaucoma (POAG) have subjective difficulties with dark (DA) adaptation and vision under low-luminance conditions and to correlate the reported difficulties with severity of disease, specifically visual field loss.

Design: Prospective, comparative case series.

Participants: Two hundred twenty patients with and without POAG who sought treatment at an outpatient subspecialty glaucoma clinic between October 2016 and September 2018.

Purpose: To evaluate outcomes after revision of failed fornix-based trabeculectomy using a posterior conjunctival incision and mitomycin C.

Methods: Cases were identified using Current Procedural Terminology codes. Information from clinical records was analyzed retrospectively.

Purpose: To compare intraocular pressure (IOP) control and other clinical outcomes after 1-site fornix-based and 2-site limbus-based phacotrabeculectomy.

Design: Prospective randomized controlled trial.

Participants: A total of 90 eyes of 76 patients with cataract and glaucoma were treated.

A telepathology network developed by Resintel (Dijon) has proved valuable in interactive situations, where two physicians converse by telephone, showing each other the part of the lesion they wish to discuss. In future this interactive process could be replaced by an electronic mailing service in which a limited number of images are taken from the slide, but this technique needs to be assessed in comparison with traditional microscopic diagnosis, when the pathologist can screen the entire slide. The present study compared diagnoses achieved through the traditional methods of current pathology practice with diagnoses achieved through a selection of images on a telediagnostic TV monitor.

Purpose: To attempt transcorneal laser sclerostomy with the erbium laser and to control the flow of aqueous through this sclerostomy with a suture ligature.

Methods: A contact erbium laser was used to create sclerostomies through small corneal incisions in both eyes of eight rabbits. Prior to surgery, a Merocel sponge soaked in mitomycin-C (0.

The objective of this work was to compare diagnoses achieved through the traditional methods of current pathology practice versus diagnoses achieved through a selection of image on a telediagnostic TV-monitor. The Kappa coefficient between the two protocols of k = 0.26 SE(k) = 0.

We have cloned cDNAs corresponding to the human gamma subunit of retinal cyclic GMP phosphodiesterase (gamma-cGMP-PDE). The coding region of these cDNAs was identical to that reported previously by Tuteja et al. (Gene 1990, 88, 227-32).

Human alpha-fetoprotein (AFP) purified from human amniotic fluid was investigated for its effect on human monocytoid cell lines, including U 937 cells with established subclones. The impact of AFP on the expression of surface markers (MHC class I and II, CD4, CD18, CD45, Fc receptors for IgG) was analyzed using known inducers of monocyte-macrophage differentiation such as phorbol esters and IFN-gamma. Furthermore we investigated the effect of AFP on the induction of macrophage antibody-dependent cell-mediated cytolytic activity (ADCC).

We used a cDNA fragment corresponding to the human cellular retinaldehyde binding protein (CRALBP) gene to search for mutations at this locus in patients with autosomal dominant, autosomal recessive, or isolate retinitis pigmentosa, and Usher's syndrome, type I. No gene deletions or rearrangements could be detected in any patient by Southern blotting. We identified a Pvu II restriction fragment length polymorphism (RFLP) defining two alleles at the CRALBP locus in the normal population.

Human fresh blood monocytes can phagocytize and lyse antibody-coated target cells by contact with membrane Fc receptors. Recently, the monocyte differentiation antigen Leu M3 has been described to be associated with monocyte/macrophage maturation pathway and to be linked to functionally distinct monocyte subsets. In the present study peripheral blood monocytes were separated into M3+ and M3- subsets, and evaluated for their ability to mediate antibody-driven effector functions.
