Purpose: Retinopathy of prematurity is a leading cause of childhood blindness worldwide, but clinical diagnosis is subjective, which leads to treatment differences. Our goal was to determine objective differences in the diagnosis of plus disease between clinicians using an automated retinopathy of prematurity (ROP) vascular severity score.

Design: This retrospective cohort study used data from the Imaging and Informatics in ROP Consortium, which comprises 8 tertiary care centers in North America.

Purpose: To report a case of varicella zoster virus associated neuroretinitis confirmed via polymerase chain reaction analysis of ocular fluid.

Observations: A 30-year-old man presented with a 1-week history of decreased vision in his left eye and ulcerative skin lesions above his left eyebrow. On exam, he had clinical findings consistent with neuroretinitis characterized by optic disc edema and formation of a macular star.

Purpose Of Review: The intestinal microbiome is thought to play a role in the pathogenesis of inflammatory bowel disease (IBD). There are many shared clinical manifestations between IBD and spondyloarthritis (SpA), of which the most common are peripheral arthritis and uveitis. Clinical overlap along with similar genetics between these diseases suggests a possible shared pathogenetic mechanism, which might center on the intestinal microbiota.

Background: Earlier studies have raised the notion that docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA) supplementation could be a useful intervention in autosomal dominant Stargardt macular dystrophy (STGD3). We sought to assess whether fish oil supplementation has a beneficial effect on the clinical course of STGD3 secondary to a mutation in the ELOVL4 gene.

Materials And Methods: Eleven patients with STGD3 were enrolled in an 8-year open-label, clinical interventional study of over-the-counter fish oil supplements at a recommended daily dose of 650 mg EPA and 350 mg DHA (NCT00420602).

Background/purpose: To report two novel cases of intermediate uveitis associated with Periodic Fever, Aphthous Stomatitis, Pharyngitis, and Cervical Adenitis syndrome.

Methods: Observational case reports and review of the literature.

Results: Both patients in this report had an established diagnosis of Periodic Fever, Aphthous Stomatitis, Pharyngitis, and Cervical Adenitis syndrome before the onset of ocular inflammation.

Purpose: To report the clinical course of a patient with ocular manifestations of hyperviscosity syndrome associated with Waldenström macroglobulinemia, and for the first time, video imaging of mobile emboli in the conjunctival and retinal vasculature.

Methods And Patient: A 60-year-old woman with newly diagnosed Waldenström macroglobulinemia, with no visual complaints was evaluated by the Ophthalmology service for a baseline ocular examination.

Results: At presentation, ocular examination revealed a visual acuity of 20/25 in each eye.

Purpose: To analyze macular pigment (MP) amount and distribution in patients with macular telangiectasia Type 2 receiving oral zeaxanthin supplementation in a randomized, open-label, interventional trial.

Methods: Eight macular telangiectasia Type 2 patients were randomized to 10 mg or 20 mg of zeaxanthin per day. At each visit, best-corrected visual acuity, contrast sensitivity, fundus biomicroscopy, color fundus photography, autofluorescence imaging, optical coherence tomography, and serum carotenoid levels were tested.

Article Synopsis
  • Eruptive vellus hair cysts are small cystic bumps that develop from abnormal vellus hair follicles, mainly appearing on the chest and upper limbs.
  • These cysts are very rare in the eye area, and there hasn't been any prior documentation of them in the orbit.
  • The authors present a case of a patient who has an eruptive vellus hair cyst located in the orbital region.

Purpose: Amphibian retinas regenerate after injury, making them ideal for studying the mechanisms of retinal regeneration, but this leaves their value as models of retinal degeneration in question. The authors asked whether the initial cellular changes after rod loss in the regenerative model Xenopus laevis mimic those observed in nonregenerative models. They also asked whether rod loss was reversible.

The anterior cruciate ligament (ACL) inserts into bone through a characteristic fibrocartilagenous interface, which is essential for load transfer between soft and hard tissues. This multi-tissue interface is lost post ACL reconstruction, and the lack of an anatomic fibrocartilage interface between graft and bone remains the leading cause of graft failure. Currently, the mechanism of interface formation is not known.
