We present a case report of a 60-year-old white woman, found to have advanced angle closure glaucoma in the right eye and appositional closure for about half of the left eye and no glaucoma. The remaining angle of the left eye was open with localized heavy pigmentation of the ciliary body band and trabecular meshwork. Ultrasound biomicroscopy showed a ciliary body tumor displacing the iris root centripetally preventing angle closure.

A 3-year-old girl treated with intravenous chemotherapy for bilateral retinoblastoma (RB) and a standard technique of intravitreal topotecan for vitreous seeds in the left eye developed a conjunctival nodule at the injection site. Ultrasound biomicroscopy showed normal underlying sclera and ciliary body. Fundus examination of the left eye showed partly calcified vitreous seeds.

Reproduction, development and homeostasis depend on motile cilia, whose rhythmic beating is powered by a microtubule-based molecular machine called the axoneme. Although an atomic model of the axoneme is available for the alga Chlamydomonas reinhardtii, structures of mammalian axonemes are incomplete. Furthermore, we do not fully understand how molecular structures of axonemes vary across motile-ciliated cell types in the body.

We examined relevant articles published from 1975 through 2022 that explored various properties of the muscle and related tissues in humans and rhesus monkeys. These properties include geometry, elasticity, rigidity, and composition, and were studied using a range of imaging technologies, computer models, and surgical methods.

In cataract surgery, post-surgical stability of the intraocular lens plays a major role. This study aims to explore how the size and decentration of the capsulorhexis affect intraocular lens decentration and tilt by using numerical methods. Finite element models included zonules, ciliary body, capsular bag, and an IOL with two open-loop haptics were built.

Rapid thrombolysis is very important to reduce complications caused by vascular blockage. A promising approach for improving thrombolysis efficiency is utilizing the permanent magnetically actuated locomotion of nanorobots. However, the thrombolytic drug transportation efficiency is challenged by in-plane rotating locomotion and the insufficient drug penetration limits further improvement of thrombolysis.
