Spaceflight associated neuro-ocular syndrome (SANS) is one of the largest physiologic barriers to spaceflight and requires evaluation and mitigation for future planetary missions. As the spaceflight environment is a clinically limited environment, the purpose of this research is to provide automated, early detection and prognosis of SANS with a machine learning model trained and validated on astronaut SANS optical coherence tomography (OCT) images. In this study, we present a lightweight convolutional neural network (CNN) incorporating an EfficientNet encoder for detecting SANS from OCT images titled "SANS-CNN." We used 6303 OCT B-scan images for training/validation (80%/20% split) and 945 for testing …

Acute Diplopia After Glabellar Hyaluronic Acid Filler Injection, Caroline W. Chung, Eric J. Shiuey, César A. Briceño, Vivian Lee

SKMC Student Presentations and Publications

Purpose: Blindness is a well-known complication of filler injection in the glabellar region. Acute diplopia from filler injection without vision loss is a rare complication that typically results in clinical ophthalmoplegia which can have permanent sequelae. Here, we describe a patient who presented with acute diplopia with grossly intact full extraocular motility after glabella hyaluronic acid filler injection that resolved after 1 month.

Observations: A previously healthy 43-year-old woman underwent her first hyaluronic acid injection in the glabella and developed immediate binocular double vision with severe pain and skin mottling above her right eyebrow and central forehead. Hyaluronidase injections, nitroglycerin …

Intraocular Lens Tilt Due To Optic-Haptic Junction Distortion Following Intrascleral Haptic Fixation With The Yamane Technique, Jordan P. Safran, Steven G. Safran

SKMC Student Presentations and Publications

Purpose: To report two patients with a complication of Yamane intrascleral haptic fixation surgery (ISHF) with the Zeiss CT Lucia 602 lens: severely tilted intraocular lens (IOL) leading to significantly decreased vision in the early post-operative period.

Observations: We report two patients presenting with severely tilted IOL implants one day and one month following Yamane ISHF. The first patient is a monocular 81-year-old woman referred for treatment of cornea edema. Initial surgery involved replacement of an anterior chamber lens with a CT Lucia 602 posterior chamber lens using Yamane technique and Descemet's stripping endothelial keratoplasty. The patient returned at one …
