Neurotrophic keratitis is a rare degenerative disease of the cornea that can lead to corneal ulceration, scarring, and significant visual impairment. It most commonly occurs in adults and is rarely diagnosed in children. Congenital corneal anesthesia...
Purpose: Chemical eye injury is an acute emergency that can result in vision loss. Neurotrophic keratitis (NK) is the most common long-term manifestation of chemical injury. NK due to alkali burn affects ocular surface health and is one of its most c...
Neuronal intranuclear inclusion disease (NIID) is a rare and slowly progressive neurodegenerative disease characterized by the presence of eosinophilic neuronal intranuclear inclusions. The clinical manifestations of NIID are diverse, and the most co...
Neurotrophins are a family of closely related secreted proteins that promote differentiation, development, and survival of neurons, which include nerve growth factor (NGF), brain-derived neurotrophic factor, neurotrophin-3, and neurotrophin-4. All ne...
Nerve growth factor (NGF), the first neurotrophin to be discovered, has a long and eventful research journey with a series of turning points, setbacks, and achievements. Since the groundbreaking investigations led by Nobel Prize winner Rita Levi-Mont...
Human allogeneic umbilical cord blood serum stands out as a potent adjunct to conventional therapies for ocular surface disorders related to severe Dry Eye Disease. By expediting ocular surface regeneration and fostering epithelial integrity, umbilic...
Background: Disruption of the corneal epithelial (CE) cell layer is a pathological feature of several ocular disorders including the potentially severe condition, neurotrophic keratitis (NK). The drug, Oxervate™, whose active principle is recom...
The measurement of corneal sensation allows clinicians to assess the status of corneal innervation and serves as a crucial indicator of corneal disease and eye health. Many devices are available to assess corneal sensation, including the Cochet&ndash...
The purpose of this study was to investigate the effect of high molecular weight hyaluronan (HMWHA) eye drops on subbasal corneal nerves in patients suffering from severe dry eye disease (DED) and to evaluate the damage of subbasal corneal nerves ass...
Persistent corneal epithelial defects (PCEDs) are a challenging ocular condition characterized by the failure of complete corneal epithelial healing after an insult or injury, even after 14 days of standard care. There is a lack of therapeutics that...
Varicella-Zoster Virus (VZV) is one of the most important pathogens in ophthalmology. Reactivation may involve the adnexa (blepharoconjunctivitis, pseudomembranous conjunctivitis), cornea (dendritic keratitis, nummular and necrotizing stromal keratit...
Background: Neuronal intranuclear inclusion disease (NIID) is a progressive neurodegenerative disorder characterized by the formation of intranuclear inclusions in cells. Adult-type NIID usually develops in elderly patients with various clinical mani...
The cornea, a highly innervated and avascular ocular tissue, relies on intricate neuro-immune interactions to maintain homeostasis. Among key neuromediators, substance P (SP)—a neuropeptide belonging to the tachykinin family—plays a dual role in corn...
The ocular surface is susceptible to a wide spectrum of inflammatory, degenerative, and neurotrophic diseases that can impair vision. The complex pathophysiology and limited therapeutic options associated with these conditions continue to pose signif...
Neurofibromatosis type 2 (NF2) is a genetically determined tumor-predisposing syndrome. Ocular manifestations include cataracts, epiretinal membranes, retinal hamartomas, optic disk gliomas, and optic nerve sheath meningiomas. Moreover, optic disk ed...
Corneal sensitivity is an important indicator of corneal health and innervation. Corneal hypoesthesia may be an early indicator of corneal diseases such as neurotrophic keratopathy. Various instruments have been used to measure corneal sensitivity, t...
The use of blood-based eye drops as therapy for various diseases of the ocular surface has become increasingly popular in ophthalmic practice during recent years. The rationale for their use is based on the promotion of cellular proliferation and mig...
Background and Objectives: Dry eye disease (DED) is a multifactorial ocular surface disease that markedly diminishes quality of life. Although diabetes mellitus is well-known for its retinal consequences, anterior segment symptoms including dry eye d...
Craniofacial and corneal neuropathic pain are disabling conditions characterized by persistent pain that is frequently refractory to conventional pharmacologic and interventional therapies. These disorders arise from complex interactions between peri...
Lamellar ichthyosis is a rare congenital disorder of keratinization frequently associated with ocular complications, most commonly cicatricial ectropion and exposure keratopathy. We present a case of severe mixed exposure-related and neurotrophic ker...
Background and Objectives: Corneal cross-linking (CXL) is the standard treatment for progressive keratoconus, but delayed epithelial healing remains a concern, increasing infection risk and patient discomfort. Studies suggest that insulin may promote...
Gabapentin (GBP) was originally developed as a potential agonist for Gamma-Amino-Butyric-Acid (GABA) receptors, aiming to inhibit the activation of pain-signaling neurons. Contrary to initial expectations, it does not bind to GABA receptors. Instead,...
Purpose. Nerve growth factor efficacy was demonstrated for corneal lesions treatment, and recombinant human NGF (rhNGF) was approved for neurotrophic keratitis therapy. However, NGF-induced molecular responses in cornea are still largely unknown. We...
Background and Objectives: Human umbilical cord blood serum (HUCBS) stands out as a potent adjunct to conventional therapies for ocular surface disorders (OSDs) caused by, among many, autoimmune systemic syndromes. By expediting ocular surface regene...
