Tear dysfunction syndrome, also known as dry eye disease (DED), is a multifactorial disease of the ocular surface characterized by the loss of tear film homeostasis. DED shows a significant clinical overlap with ocular allergy (OA), which alters tear film homeostasis, thus predisposing the patient to DED. Both conditions constitute the most common ocular surface disorders and have a potentially severe impact on patients' quality of life. Clinical practice guidelines recommend topical therapies as first-line treatment for OA. However, eye drop formulations may contain additional substances that can contribute to ocular surface damage and the development of DED. Therefore, physicians treating ocular allergy should be aware of problems affecting the tear film, the role of tear film disruption in OA, and topical treatment to prevent or minimize DED. The aim of this review is to present an updated overview of the topic.

Background: Overexpression of tear matrix metalloproteinases-9 (MMP-9) on the ocular surface tissues has been reported to result in ocular surface damage. MMP-9 levels in tears have been listed as one of many tools for confirming dry eye disease (DED).
Objective: This investigation aimed to compare MMP-9 levels and ocular surface parameters in diabetic patients with and without DED.

Introduction: Meibomian Gland Dysfunction (MGD) represents the most common cause of dry eye disease (DED). Traditional treatments mainly rely on heating and liquifying the meibum to favor its expression. However, recent knowledge advances have led to the development of novel therapies specifically designed for patients with MGD.

Dry eye disease (DED) is a multifactorial condition with complex and incompletely understood molecular mechanisms. Advances in multi-omics technologies, including genomics, transcriptomics, proteomics, metabolomics, and microbiomics, have provided new insights into the pathophysiology of DED. Genomic analyses have identified key genetic variants linked to immune regulation and lacrimal gland function.

Aims: To understand current clinical management of dry eye disease (DED), based on its perceived severity and subtype by practitioners across the world.
Methods: The content of the anonymous survey was chosen to reflect the DED management strategies reported by the Tear Film and Ocular Surface Society (TFOS) 2 Dry Eye Workshop (DEWS II). Questions were designed to ascertain practitioner treatment choice, depending on the subtype and severity of DED.

Dry eye disease (DED), a prevalent ocular disorder, affects nearly half the global population, bringing enormous health and economic burden. Currently, the predominant treatments for DED involve the administration of artificial tears, which is often hindered by continuous administration and constant reactive oxygen species (ROS) stimulus. Therefore, hyaluronan (HA)-modified cerium oxide (CeO) nanoparticles, HA-CeO, were developed to achieve simultaneous ROS scavenging and enhanced tear film stability.
