Purpose Of The Study: Radioiodine (RAI) has been used for the treatment of hyperthyroidism and well-differentiated thyroid carcinoma for more than 70 years. Lycopene is an anti-oxidant, which is plentiful in red fruits. The purpose of this study was to investigate the possible inhibitory effect of lycopene on the RAI-induced acute histopathological changes in rat lacrimal glands.
Methods: In this experimental animal study, 32 rats were randomly divided into three groups. The first group (control group, n = 8) was not given neither (131)I nor lycopene, the second group (RAI group, n = 12) was administrated a single dose of 3 mCi (131)I and 1 cc physiologic saline by gastric gavage. The third group (lycopene group, n = 12) was administrated 3 mCi (131)I and 1 cc lycopene by gastric gavage. After 24 h of the last dose, the animals were decapitated on the seventh day and their lacrimal glands were removed for histopathological examination.
Results: The cell shape and the cell size variation and poorly defined acidophilic cell outlines in all lacrimal glands were observed significantly less frequently in the lycopene group than in the RAI group.
Conclusions: Our histopathological examinations have revealed that lycopene prevents rat lacrimal glands against RAI-related acute histopathological changes.

Sjögren's syndrome-related dry eye (SSDE) is a severe dry eye subtype characterized by significant immune cell attacks on the lacrimal gland. However, delivering immunosuppressive drugs to the lacrimal glands for SSDE therapy safely and sustainably poses significant challenges in clinical practice. Herein, a ROS-responsive microneedle patch with detachable functionality (CE-MN) is developed to enable straightforward and minimally invasive administration to the lacrimal gland area by penetrating the periocular skin.

Purpose: Chronic jet lag (CJL) is known to disrupt circadian rhythms, which regulate various physiological processes, including ocular surface homeostasis. However, the specific effects of CJL on lacrimal gland function and the underlying cellular mechanisms remain poorly understood.
Methods: A CJL model was established using C57BL/6J mice.

Purpose: This study investigated the impact of hyperglycemia in type 2 diabetes mellitus (T2DM) on the circadian rhythms and function of lacrimal glands (LGs) in contributing to dry eye syndrome. We assessed the effects of hyperglycemia on circadian gene expression, immune cell recruitment, neural activity, and metabolic pathways, and evaluated the effectiveness of insulin in restoring normal LG function.
Methods: Using a T2DM mouse model (db/db mice), circadian transcriptomic changes in LGs were analyzed through RNA sequencing over a 24-hour period.

Primary Sjögren's syndrome (pSS) is an autoimmune disease characterized by the infiltration of lymphocytes on salivary and lacrimal glands, resulting in their dysfunction. Patients suffering from severe pSS have an increased risk of developing multi-organ dysfunction syndrome due to the development of systemic inflammatory response, which results in immune cell-driven injury of the lungs, kidneys, liver, and brain. Therapeutic agents that are used for the treatment of severe pSS encounter various limitations and challenges that can impact their effectiveness.

Background: Primary acquired nasolacrimal duct obstruction (PANDO) is a condition in which tear ducts are blocked, leading to epiphora and dacryocystitis. This systematic review and meta-analysis aimed to measure the ability of transcanalicular dacryocystorhinostomy (TC-DCR) as an alternative approach to PANDO compared to traditional external dacryocystorhinostomy (EX-DCR).
Methods: Our search included Embase, Medline, and the Cochrane Central Register of Controlled Trials (CENTRAL).
