Dynamic Contrast Microscopic Optical Coherence Tomography As a Novel Method for Assessing Corneal Epithelium During Exposure to Benzalkonium Chloride.

Transl Vis Sci Technol 2022 05;11(5):28

Institute of Biomedial Optics, University of Lübeck, Lübeck, Germany.

Purpose: Microscopic optical coherence tomography (mOCT) has an imaging resolution of 1 µm in all voxel dimensions, but individual epithelial cells are difficult to resolve due to lack of scattering contrast. Adding dynamic contrast processing to mOCT (dmOCT) results in color images that enable visualization of individual cells and possibly give information on cellular function via the calculation of a motility coefficient. We propose this technique as a novel method of evaluating the ocular surface after exposure to a toxic chemical, benzalkonium chloride (BAK). Read More

The MOLES system to guide the management of melanocytic choroidal tumours: can optometrists apply it?

Clin Exp Optom 2022 Feb 13:1-5. Epub 2022 Feb 13.

Ocular Oncology Service, Moorfields Eye Hospital, London, UK.

Clinical Relevance: Although melanocytic choroidal tumours of the choroid are a common eye pathology, no standardised protocol exists for their management in the community.

Background: Choroidal naevi are found in approximately 6% of the adult White population, whereas choroidal melanomas are rare, with an annual incidence of 5-10/million/year. Multimodal imaging has advanced the understanding of malignancy imaging biomarkers, but distinguishing between a small melanoma and naevus remains difficult and an algorithm for their management by community practitioners has not been uniformly adopted.

A review of neovascular glaucoma. Etiopathogenesis and treatment.

Rom J Ophthalmol 2021 Oct-Dec;65(4):315-329

Department of Ophthalmology and Optometry, "Nicolae Testemițanu" State University of Medicine and Pharmacy, Chișinău, Republic of Moldova.

Neovascular glaucoma (NVG) is a type of secondary glaucoma, refractory to treatment, often incurable, with very poor visual prognosis. It is characterized by the appearance of new vessels over the iris and iridocorneal angle and frequently associates the presence of a fibrovascular membrane which limits the aqueous humor outflow from the anterior chamber. The most common causes of NVG are: central retinal vein occlusion, proliferative diabetic retinopathy, and ocular ischemic syndrome. Read More

Optic Nerve Ultrasound Evaluation in Animals and Normal Subjects.

Front Med (Lausanne) 2021 5;8:797018. Epub 2022 Jan 5.

Eye Unit, Department of Medicine, Surgery and Dentistry, "Scuola Medica Salernitana", University of Salerno, Baronissi, Italy.

In recent years, ultrasonographic measurement of the optic nerve sheath diameter (ONSD) has been widely used to identify the presence of increased intracranial pressure (ICP). Intracranial hypertension is a life-threatening condition that can be caused by various neurological and non-neurological disorders, and it is associated to poor clinical results. Ultrasonography could be used to qualitatively and efficiently detect ICP increases, but to reach this purpose, clear cut-off values are mandatory. Read More
