Torsion-Induced Traumatic Optic Neuropathy (TITON): A Physiologically Relevant Animal Model of Traumatic Optic Neuropathy.

Traumatic optic neuropathy (TON) is a common cause of irreversible blindness following head injury. TON is characterized by axon damage in the optic nerve followed by retinal ganglion cell death in the days and weeks following injury. At present, no therapeutic or surgical approach has been found to offer any benefit beyond observation alone.

Prospective Comparison of VisuALL Virtual Reality Perimetry and Humphrey Automated Perimetry in Glaucoma.

Aim And Background: Automated perimetry plays an important role in the diagnosis and monitoring of glaucoma patients. The purpose of this study is to prospectively determine parity between Humphrey visual field analyzer (HVFA) perimetry (the current gold standard) and the VisuALL virtual reality perimeter (VRP).

Materials And Methods: In this prospective fully paired diagnostic accuracy study, patients with stable, long-term HVFA visual fields (horizontal dots for ≥4 consecutive visits on progression analysis) with preperimetric, mild, moderate, or severe visual field loss were familiarized with the VRP and then tested using its proprietary software.

COVID-19 Related Acute Macular Neuroretinopathy (AMN): A Case Series.

Purpose: Following the emergence of coronavirus disease 2019 (COVID-19) eye care practitioners have become accustomed to identifying and managing an array of ocular complications following the viral infection. Acute macular neuroretinopathy (AMN) is one such complication that has been reported. While the etiology of AMN has eluded researchers, current literature is suggestive of a microvascular compromise within the deep capillary plexus of the retina.

Rotational extraction of incarcerated iris (REII): a slit lamp technique to reduce incarcerated iris after nonpenetrating deep sclerectomy for glaucoma.

Purpose: Iris incarceration is a complication of glaucoma filtering surgery that often requires surgery. We describe a technique for reduction of incarcerated iris at the slit lamp, dubbed rotational extraction of incarcerated iris (REII). A retrospective analysis of visual function and intraocular pressure (IOP) was done in patients treated with REII after nonpenetrating deep sclerectomy.

Digital Ocular Compressions Reduce Intraocular Pressure in Eyes With Tube Shunts.

Prcis: Digital ocular compressions (DOCs) decrease intraocular pressure in eyes with tube shunts by significantly greater magnitude and duration when compared with fellow eyes without filtering surgery.

Purpose: DOCs are commonly used by glaucoma surgeons to reduce intraocular pressure (IOP) in the early postoperative period. Little is known, however, about the effects of DOC in eyes with tube shunts.
