Purpose Of Review: Post-traumatic orbital reconstruction is a complex issue that involves both the soft tissue and bony injury. The current literature focuses primarily on bony reconstruction, with fewer investigators evaluating soft-tissue injuries. This article will review recent advances in orbital reconstruction, including presurgical planning software, intra-operative navigation, patient-specific implants, and intra-operative imaging.
Recent Findings: Traditional techniques for diagnosis and orbital injuries continue to be refined; however, advances in computer-aided surgery are allowing surgeons to significantly improve the anatomic accuracy of orbital reconstruction.
Summary: While not all surgeons currently have access to computer-aided applications for orbital reconstruction, these techniques will continue to be refined, resulting in lower cost and greater access.

Purpose: This work aims at investigating, via in-silico evaluations, the noise properties of an innovative scanning geometry in cone-beam CT (CBCT): eCT. This scanning geometry substitutes each of the projections in CBCT with a series of collimated projections acquired over an oscillating scanning trajectory. The analysis focused on the impact of the number of the projections per period (PP) on the noise characteristics.

Pump-probe response of the spin-orbit coupled Mott insulator Sr_{2}IrO_{4} reveals a rapid creation of low-energy optical weight and suppression of three-dimensional magnetic order on laser pumping. Postpump there is a quick reduction of the optical weight but a very slow recovery of the magnetic order-the difference is attributed to weak interlayer exchange in Sr_{2}IrO_{4} delaying the recovery of three-dimensional magnetic order. We suggest that the effect has a very different and more fundamental origin.

Purpose: Phenylephrine testing prior to Müller muscle conjunctival resection has traditionally been used to predict postoperative outcomes. The purpose of this study is to determine if preoperative phenylephrine testing impacts postoperative changes in eyelid position.
Methods: In this multicenter cross-sectional cohort study, 270 eyelids of participants with involutional ptosis and levator function >12 mm who underwent Müller muscle conjunctival resection were divided into 2 comparison groups.

Background: Positron emission tomography (PET) imaging greatly impacted Alzheimer's disease (AD) research and diagnosis. which makes predicting PET brain imaging alterations using blood data is of high interest. Additionally, integrating PET and omics data can provide new insights into AD pathophysiology.

Loss of periocular skin due to cancer, trauma, or surgery is a major reconstructive challenge; resultant tissue contracture can cause eyelid malposition with poor functional and aesthetic outcomes. We describe the successful use of cryopreserved umbilical cord amniotic membrane as a wound covering and scaffold for periorbital anterior lamellar defects. This is a retrospective case series of 4 patients (mean 21 years, range 9-30 years, 3 male) who underwent periocular reconstruction with umbilical cord amniotic membrane of 9 different sites.
