Background: The blue hue of skin overlying injected hyaluronic acid (HA) fillers in certain cases has been hypothesized in the literature as related to the Tyndall effect. This investigation aims to understand the relevant optical concepts and to discuss the plausibility of this assertion.
Methods: Theoretic and physical aspects of relevant optical theories including the Tyndall effect, the Raleigh criterion and the Mie Solution are discussed, with simple examples.
Background: High-resolution ultrasound (HRUS) is a useful tool in defining anatomic and dynamic soft tissue relationships in the periocular area. It also allows visualization of hyaluronic acid (HA) gel within the soft tissue.
Objectives: The authors investigate the difference in the distribution pattern between 2 HA fillers in the periocular tissue using HRUS.
Background: High-resolution ultrasound (HRU) imaging is a useful tool to study hyaluronic acid (HA) filler injected in the face.
Objective: To observe real-time injection of HA using HRU and describe behavior of the gel injection in various anatomic layers and the effect of massage.
Methods: Deep (preperiosteal), intermediate (subdermal), and superficial (dermal) injections of HA were performed in the supraclavicular area under ultrasonography visualization on a healthy volunteer.
Purpose: To report a patient with bilateral corneal perforations and autoproptosis in a case of ocular Munchausen's syndrome.
Design: Case report.
Participant: A 26-year-old white male referred to the oculoplastics service with one month history of decreased vision bilaterally and painful right eye.
