Documented Reperfusion of the Retina on Fluorescein Angiography after Administration of Intravenous Prostaglandin E1 for Central Retinal Artery Occlusion: A Case Report.

Central retinal artery occlusion (CRAO) can result in devastating permanent vision loss. Presently, there is no evidence-based treatment for CRAO that is widely accepted. In the literature, multiple studies propose intravenous (IV) prostaglandin E1 (IV PGE1) as a potential treatment option for patients with CRAO.

Outcomes in Sutured Versus Sutureless Wound Closure in Pediatric Cataract Surgery.

Purpose: To analyze the postoperative course, specifically postoperative complications, of pediatric patients who underwent cataract surgery by a single surgeon. The type of wound closure was compared to provide an evidence-based approach to surgical technique in pediatric cataract surgery.

Methods: This retrospective study analyzed pediatric patients who underwent cataract extraction by a single surgeon from 2014 to 2020.

Case series: Two cases of herpetic retinitis presenting as progressive outer retinal necrosis in immunocompetent individuals.

Purpose: To raise awareness of ophthalmologists that Varicella Zoster Virus (VZV) retinitis should be considered in the differential diagnosis of retinitis that presents with features of progressive outer retinal necrosis (PORN) in healthy immunocompetent patients.

Observations: Case 1 is a 39-year-old healthy Caucasian male who presented after one week of decreased vision in the left eye. Patient was found to have optic disc edema and multifocal retinitis primarily localized to the posterior pole with only a few lesions in the periphery and minimal vitritis.

Two Patients with Atypical Choroidal Detachment.

Serous choroidal detachment that is caused by rhegmatogenous retinal detachment (RRD) may present a significant diagnostic challenge as delayed recognition and repair of the underlying RRD can severely impact the final anatomical and visual outcome. We report 2 consecutive patients with atypical choroidal detachments who were later found to have underlying RRDs. A 71-year-old female presented with a 1-week history of painful vision loss and floaters in the left eye.

Defining the Anatomy of the Tendinous Intersections of the Rectus Abdominis Muscle and Their Clinical Implications in Functional Muscle Neurotization.

Purpose: Little is known about the definitive course of the tendinous intersections from anterior to posterior through the rectus abdominis (RA) muscle. The implications of a full thickness intersection may have effects on the ability to neurotize the RA. We hypothesized that these tendinous inscriptions would be fully adherent to the anterior rectus sheath, but there would be an incomplete penetrance into the posterior surface, thereby allowing for muscle fibers and neurovascular structures to run the entire course of the RA muscle.

Involvement of AMPA Receptor and Its Flip and Flop Isoforms in Retinal Ganglion Cell Death Following Oxygen/Glucose Deprivation.

Purpose: The α-amino-3-hydroxy-5-methyl-4-isoxazoleproprionic acid (AMPA) receptors (AMPAR) subunits can be posttranscriptionally modified by alternative splicing forming flip and flop isoforms. We determined if an ischemia-like insult to retinal ganglion cells (RGCs) increases AMPAR susceptibility to s-AMPA-mediated excitotoxicity through changes in posttranscriptional modified isoforms.

Methods: Purified neonatal rat RGCs were subjected to either glucose deprivation (GD) or oxygen/glucose deprivation (OGD) conditions followed by treatment with either 100 μM s-AMPA or Kainic acid.
