NCT07671222
Sjögren's syndrome is a condition in which the immune system attacks the body's moisture-producing glands. This often causes severe dry eye, leading to discomfort, irritation, blurred vision, and damage to the eye surface. Inflammation plays an important role in this process, and a protein called TNF-alpha is one of the key drivers. This study will test a new eye drop containing infliximab, a medication that blocks TNF-alpha. The goal is to see whether this treatment can safely improve symptoms and signs of severe dry eye in patients with Sjögren's syndrome.
NCT07656688

NCT07605572
Diabetes mellitus (DM), prediabetes, and obesity are emerging as major global public health problems, with their epidemic spread continuously increasing over the past decades. The occurrence of diabetic retinopathy, cataract, glaucoma, and ocular surface disease in patients with diabetes mellitus has been extensively investigated in several studies. However, mild ocular surface disorders, such as dry eye disease, have often been overlooked, with a previous study showing that 51.3% of diabetes-related dry eye disease cases remained underdiagnosed. Among systemic diseases, diabetes mellitus and obesity have been associated with an increased risk of developing dry eye disease. Chronic hyperglycemia in diabetes leads to microvascular damage, including corneal neuropathy and reduced tear production, conditions that can disrupt ocular surface health, while systemic inflammation and meibomian gland dysfunction also contribute to this process. However, the effect of newer classes of antidiabetic medications, including glucagon-like peptide-1 receptor agonists (GLP-1 RAs), on ocular surface health remains insufficiently understood. The aim of this prospective cohort study is to evaluate the effects of GLP-1 receptor agonists on dry eye disease in patients with type 2 diabetes mellitus and obesity through the assessment of ocular surface parameters, such as tear film break-up time, Schirmer test results, as well as potential changes in corneal topography.
NCT07245836
Dry eye disease (DED) is a highly prevalent ocular condition and induces a significant burden to the affected patients. Regardless of the underlying etiology, DED is associated with increased inflammation of the entire ocular surface including the adnexa, conjunctiva and cornea. As such, there is evidence from in vitro, animal and clinical studies that this inflammatory response of the ocular surface plays a pathophysiological key role in the development of DED. The Dry Eye Workshop 2007 (DEWS) therefore suggests beside of restoring the tear film by administering topical lubricants, breaking the vicious circle of inflammation is an important mainstay of therapy in patients with DED. Recently, a new medical device (Thealoz Total® eye drops) has been introduced for the treatment DED. Thealoz Total® eye drops are based on hyaluronic acid and exert their main action by lubricating the ocular surface. Further, this new formulation offers several advantages that make them potentially interesting to reduce DED related symptoms. First, the formulation is preservative-free, which is of special importance in patients with DED, since it has been shown that preservatives are detrimental for the ocular surface. thereby reducing signs and symptoms related to DED. Secondly, in addition to the lubricating effect of hyaluronic acid, Thealoz Total eye drops also contain trehalose, which exerts osmoprotetive effects and N-Acetyl Aspartyl Glutamic Acid (NAAGA). NAAGA is an amino conjugated dipeptide with anti-inflammatory properties. Thus, it is reasonable to hypothesize that Thealoz total eye drops are also capable of reducing ocular surface inflammation. The aim of the present study is to investigate whether topical administration with Thealoz Total® improves ocular surface inflammation as well as clinical signs and symptoms associated with DED.
NCT07525336

The study duration will be up to 16 weeks and will consist of three periods.
NCT07463950
Dry eye disease (DED) is a common, multifactorial ocular surface condition with increasing worldwide prevalence. DED induces a significant burden to the patients. Inflammatory responses involving the ocular surface including the adnexa, conjunctiva and cornea are recognized as central to its pathophysiology, as supported by in vitro, non-clinical and clinical studies. Although tear substitutes remain the mainstay of initial management, in some patients this is not sufficient to control ocular surface inflammation and associated symptoms. A new medical product (Vevizye® eye drops) has been recently approved for the treatment of DED. It contains cyclosporine 0.1% as an active ingredient and pefluorobutylpentane as vehicle. Topical cyclosporine is a well-established treatment for patients with moderate to severe DED who do not achieve sufficient clinical benefit from topical lubricants alone. Perfluorobutylpentane has been found to improve the bioavailability of cyclosporine and has a long residence time for up to 8 hours. In addition, because of its low surface tension facilitates quick and uniform spreading improving the tear film layer. The FOCUS study aims to evaluate the clinical efficacy of 0.1% cyclosporine eye drops solution (Vevizye®, Laboratoires THEA) in patients with moderate to severe DED characterized by ocular surface inflammation.
NCT07412860
The goal of this clinical investigation plan is to evaluate the performance, tolerability, safety, and compliance of an ophthalmic solution containing an ancillary medicinal substance and hyaluronic acid 0.3% (FBV\_01) compared with hyaluronic acid 0.3% alone in adult men and women (≥18 years) with moderate-to-severe dry eye syndrome. The main questions it aims to answer are: * Is the ophthalmic solution containing an ancillary medicinal substance and hyaluronic acid non-inferior in improving the clinical performance outcomes of dry eye compared with hyaluronic acid alone? * Is the investigational device safe and well tolerated, with acceptable partecipant compliance over the treatment period? Researchers will compare the medical device containing an ancillary medicinal substance and hyaluronic acid 0.3% (FBV\_01) to hyaluronic acid 0.3% alone to see if the combination provides at least equivalent clinical benefit without increased safety issues. Participants will be randomly assigned (1:1) to one of two treatment groups in a multicenter, prospective, randomized, open-label, controlled study. Participants will instill 1 drop in both eyes 4 times daily (every 4 ± 1 hours) for 30 ± 4 days and attend study visits for assessments of dry eye signs and symptoms, safety, tolerability, and treatment compliance. The study plans to enroll 74 partecipants, with an enrollment period of about 11 months and a total study duration of approximately 12 months (from first partecipant first visit to last partecipant last visit).

NCT07341724
Dry eye disease (DED) is a common eye condition that is becoming more widespread. Detecting it early, keeping track of its progression, and following up regularly can help protect vision and prevent serious complications. However, due to a shortage of ophthalmologists, limited access to eye care services, and disparities in care quality, many patients receive infrequent or insufficient clinical consultations. To address these needs, a portable automatic ocular surface imaging device (PAOSID) that attaches to a mobile phone has been developed. This device uses three types of light including white, infrared, and cobalt blue light to capture clear images and videos of the eye's surface. It also has a smart system that automatically takes high-quality images, allowing patients to use it at home independently. This device may help detect early signs of DED and monitor eye health more easily.

The primary aim is to characterize the rapidity of symptomatic relief in moderate to severe dry eye disease (DED), with attention to short-term therapy.
NCT06981104
At present, research on cyclosporine mainly focuses on patients with moderate to severe dry eye. Based on the importance of the vicious cycle of inflammation in the pathogenesis of dry eye and the mechanism of cyclosporine, investigators believe that it may also have therapeutic effects in patients with mild to moderate dry eye, and may have certain advantages compared to traditional artificial tear therapy. In summary, this study intends to use a randomized, double-blind, parallel controlled trial to evaluate the therapeutic efficacy and safety of 0.05% cyclosporine eye drops in patients with mild to moderate dry eyes.
