Pigment dispersion syndrome is seen in many conditions, such as, viral iridocyclitis, uveitis, and bilateral acute iris transillumination. The most common of which is herpes simplex virus and varicella zoster virus causes viral iridocyclitis, uveitis. Herpes Zoster Ophthalmicus (HZO) does not a fatal cause but a blind cause as well as prolonged pain leads to disturbance and difficulty in treatment for patients, and may be a marker for AIDS particularly in young persons.

Abstract:
Optic nerve head (ONH) cupping is a clinical feature of glaucoma associated with extracellular matrix (ECM) remodelling and lamina cribrosa (LC) fibrosis. Peripapillary atrophy (PPA) occurs commonly in glaucoma, and is characterised by the loss of retinal pigment epithelium (RPE) adjacent to the ONH. Under pro-fibrotic conditions, epithelial cells throughout the body can differentiate into fibroblast-like cells through epithelial-to-mesenchymal transition (EMT) and contribute to ECM fibrosis. This is investigated here in the context of glaucoma and PPA. Human-donor ONH sections were assessed f

Abstract:
Relevance Pigment dispersion syndrome (PDS) is a condition characterized by the release of pigment from the posterior pigment layer of the iris, deposited on various structures of the anterior segment of the eye [1]. The main cause of this condition is friction of the posterior surface of the iris against the anterior surface of the lens and its ligamentous apparatus. It is most common in young men with myopic refraction. Pigment dispersion syndrome is usually asymptomatic, but with significant physical exertion, especially associated with severe shaking, periods of transient blurred vision ma

Abstract:
Frank-Kamenetsky syndrome is a rather rare ocular anomaly, which is characterized by hypoplasia of the iris stroma with exposure of its pigment layer and the development of secondary glaucoma, more often in the 2-3rd decade of life. Gonioscopy reveals goniodysgenesis in the form of "dentate" and anterior attachment of the root of the iris of a dirty gray color, as well as the inclusion of mesodermal tissue in the trabecular zone. The severity of the course of glaucoma is determined by the age of onset and is often malignant, gradually leading to blindness. Frank-Kamenetsky syndrome is observed

Age–related macular degeneration (AMD) is a progressive disease that steadily leads to blindness and manifests itself as a chronic degenerative process in the pigment epithelium, Bruch's membrane and choriocapillary layer of the macular zone of the retina. Spectral optical coherence tomography (SOCT) is the most informative method of morphometric examination in patients with retinal diseases. Among the functional ones, static automatic perimetry (SAP) is the most informative, which makes it possible to evaluate the features of changes in the central field of vision, indicating the quanti

AbstractCa2+/calmodulin-dependent protein kinase II (CaMKII) is a family of broad substrate specificity serine (Ser)/threonine (Thr) protein kinases that play a crucial role in the Ca2+-dependent signaling pathways. Its significance as an intracellular Ca2+ sensor has garnered abundant research interest in the domain of neurodegeneration. Accumulating evidences suggest that CaMKII is implicated in the pathology of degenerative retinopathies such as diabetic retinopathy (DR), age-related macular degeneration (AMD), retinitis pigmentosa (RP) and glaucoma optic neuropathy.
