Purpose: To investigate clinical, anatomic and electroretinographic changes in eyes that suffered blunt ocular trauma with commotio retinae.
Methods: Patients who presented commotio retinae after unilateral blunt ocular trauma less then 72 hours before were submitted to visual acuity testing, biomicroscopy, binocular indirect ophthalmoscopy, fluorescein angiography, optical coherence tomography and full-field electroretinography. Full-field ERG was repeated after 15 and 30 days.
Results: Sixteen patients were included in the study. On the first examination there was a statistically significant difference between affected and fellow eye in all response amplitudes, without b/a ratio alteration, and a delay in single-flash cone response and 30-Hz flicker implicit time. On the second examination, the difference between the eyes remained for oscillatory potentials, but disappeared on the last examination. In fluorescein angiography, all patients presented mottled hyperfluorescence and hypofluorescent areas, due to alterations in the pigment barrier. On optical coherence tomography, we found optically empty spaces at the site of the lesion.
Conclusion: Found changes suggested photoreceptor and ganglion cells, but not Müller cell functional alterations, as well as pigment mobilization. These changes disappeared 30 days after the trauma.

Radiology, NHS, Essex, GBR.
CT is the gold standard for evaluating orbital trauma, providing rapid and detailed imaging of bony structures, soft tissue, and the globe. This is crucial in assessing orbital trauma due to its potential to cause significant impairment of ocular function. This case report presents a 35-year-old male who was admitted to the emergency department with a complicated left orbital blow-out fracture following blunt facial trauma.

Material And Methods: The study included 28 eyes of 28 patients, 19 (68%) of whom were men, with an average age of 46 years. They were operated on by a single surgeon for RRD at the Eye Clinic of the University Hospital and Faculty of Medicine, Masaryk University in Brno, from July 1, 2019, to April 30, 2023, using cryosurgical techniques and/or 25G+ pars plana vitrectomy (PPV).
Traumatic Hyphema with Commotio Retinae in a Special Operations Environment.

Traumatic ocular injuries from both combat- and noncombat-related activity remain a significant burden in active duty Ser- vicemembers and present a diagnostic and therapeutic challenge to Special Operations medics with limited resources in far forward and remote areas. Blunt ocular injury, whether from sports or battlefield engagement, can result in a variety of eyesight-threatening injuries, including hyphema, commotio retinae, iritis, uveitis, and open globe injury. The management of these conditions often requires teleconsultation with ophthalmology and potential evacuation, which is tailored to the resources available for the Special Operations Forces medic.

Article Synopsis
- * Emergency surgery successfully addressed the injuries, including closing a macular hole, allowing the player to return to training in six weeks and competitive play in eight weeks.
- * This case underscores the importance of quick medical response to prevent serious long-term consequences for athletes, even in sports typically considered low-risk for eye injuries, like soccer.
Background: Iridodialysis, the separation of the iris root from the ciliary body, typically results from trauma and can lead to significant visual impairment. This case report is novel as it demonstrates the successful management of iridodialysis using an extended depth of focus intraocular lens in a patient with a slightly irregular pupil.
Case Presentation: A 34-year-old Hispanic man presented with reduced vision and pain in his right eye following blunt trauma from a nail at work.
