Keratoconus and Corneal Ectasia with Relatively Low Keratometry

Ophthalmology and Therapy
Introduction The study aims to demonstrate and estimate the prevalence of clinical corneal ectasia and keratoconus (KC) in patients with relatively low keratometry (low-K KC). Methods In a retrospective, analytical, and non-interventionist study, one eye

Corneal tomography in osteogenesis imperfecta [PDF]

, 2020
Osteogenesis Imperfecta (OI) is a rare genetic disorder with musculoskeletal manifestations and some ocular features, such as the presence of blue sclerae, corneal thinning, altered corneal biomechanics, and rare reports of keratoconus (KC).

Tumbling Magnetic Microrobots for Targeted In Vivo Drug Delivery in the GI Tract

Advanced Robotics Research, EarlyView.
We introduce a microrobot design and integrated system for on‐demand targeted drug release in the gastrointestinal tract. The microrobot has an embedded magnet for actuation with external magnetic fields and is visualized in real time using ultrasound. It has two drug release ports sealed with a thermally sensitive wax. Local heating of the wax using a

Engineering Approaches to Modify Immunomodulatory Functions of Mesenchymal Stromal Cells (MSCs): Tissue Regeneration and Clinical Application

Advanced Science, EarlyView.
Mesenchymal stromal cells (MSCs) show promise for treating immune‐related disorders through immunomodulation and tissue regeneration. This review gives a brief overview of current clinical approval of MSC therapies. It also discussed how bioengineering, including genetic modification, biomaterial delivery, extracellular vesicles, and iPSC‐derived MSCs,

Diagnosis of keratoconus with optical coherence tomography

Journal of the Egyptian Ophthalmological Society, 2016
Purpose The aim of the study was to assess the accuracy of optical coherence tomography (OCT) (3D OCT-2000) in diagnosing keratoconus by measuring the central corneal thickness and the central curvature radius.

Detailed corneal and genetic characteristics of a pediatric patient with macular corneal dystrophy - case report

BMC Ophthalmology, 2021
Background Corneal dystrophies are a group of rare, inherited disorders that are usually bilateral, symmetric, slowly progressive, and not related to environmental or systemic factors. The majority of publications present the advanced form of the disease

Corneal elevation topography and corneal optical coherence tomography (OCT) images.

, 2014
Anterior corneal elevation topography and cross-sectional corneal optical coherence tomography (OCT) images at the steepest (A, C) and flattest meridians (B, D) were taken for one keratoconic eye and one healthy eye with high corneal astigmatism.
