NCT07632534
Dry eye syndrome is a multifactorial pathology of the ocular surface. Epidemiological studies report a prevalence of 15% in adults aged between 50 and 95. Depending on the severity of the disease, different treatment strategies may be proposed. The use of autologous serum eye drops (AS) represents an interesting therapeutic alternative for the most severe forms of the disease, due to the serum's composition, which is similar to that of tears. The mechanism of action of AS is still controversial, but is probably multifactorial and seems to be based on growth factors, vitamin factors and anti-inflammatory factors. The clinical response of patients could be dependent on the protein composition of the eye drops. The investigators are aiming to highlight a difference in serum protein composition that could explain the differences in clinical response between patients treated with autologous serum eye drops and to identify the proteins that would be involved in a clinical response or non-response.
NCT05481450

NCT06220474
The goal of this prospective, 24-week, double-masked, randomized, sham-controlled clinical trials to compare clinical efficacy and safety of RF and MGX with MGX alone in patients with meibomian gland dysfunction-related dry eye disease. The main question it aims to answer is whether radiofrequency treatment and meibomian gland expression is more effective in improving tear breakup time, as measured using non-invasive video keratography, compared with meibomian gland expression alone, in patients with refractory meibomian gland dysfunction-related dry eye disease. Participants will be divided into two groups, one group will receive RF treatment followed with MGX and another will receive sham treatment with MGX.
NCT06190028
The main aim of this investigation is to evaluate the effect of the preservative-free ophthalmic solution IRIDIUM® A gel on the ocular surface of patients with glaucoma or OHT and concomitant DES under multiple long-term topical hypotensive therapy for at least 6 months. The underlying assumption is that ophthalmic solutions as adjuvants for the management of IOP- or glaucoma-associated dry eye may induce a protection of the eye surface with consequent improvement of the symptoms and of the overall quality of life.
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).

NCT04425551
The modern treatment of meibomian gland dysfunction(MGD) is based on anti-inflammatory drops or oral antibiotics for decreasing dry eye disease (DED) associated inflammation, warm compresses for liquefying the thicker meibum, and lid hygiene for reducing the bacterial overload. But, such treatments have shown limited effectiveness to a large proportion of patients with MGD, due to the multifactorial background of the disease. Thus, alternative approaches aiming at different aspects of the DED pathophysiology are needed. Elimination of posterior lid-margin hyperemia with telangiectasia could be a treatment target for reducing the secretion of inflammatory mediators in the course of MGD. Using the mechanism of photocoagulation via selective thermolysis, laser light could contribute to the destruction of abnormal vessels at the posterior lid-margin and thus, the reduction of inflammation. Recently, sub-threshold (micropulse) laser photocoagulation was introduced in ophthalmology and offers significant clinical advantages compared to conventional continuous wave (CW) approach, preventing laser induced thermal damage and related treatment side effects. This study investigates the effect of sub-threshold (micropulse) laser treatment for dry eye disease due to meibomian gland dysfunction combined with increased eyelid margin vascularity.
NCT07295691
This study aims to evaluate the clinical efficacy and safety of autologous serum eye drops (ASEDs) in patients with moderate-to-severe dry eye syndrome who are refractory to conventional artificial tear therapy.
NCT07267481
To determine the efficacy of switching participants who are being treated with Xiidra to acoltremon 0.003%. Hypothesis: Switching to acoltremon 0.003% will greatly improve the signs and symptoms of participants who were being treated with Xiidra at 28 days post-treatment compared to baseline.
NCT03804502
The objective of the study is to evaluate the long-term clinical utility, safety, and effectiveness of re-treatment with the TearCare™ System in adult patients with dry eye syndrome who had previously been treated with the TearCare System.
NCT03135327
The purpose of this study is to determine the clinical application of advanced ophthalmic imaging devices such as optical coherence tomography (OCT), retinal function imager (RFI), slit-lamp biomicroscopy (SLB), PERG in diseased eyes and normal controls. There are two phases in this study. The first phase is an observational phase which studies the eye in various conditions. The second phase is an interventional phase which studies the changes in the eyes after taking an over-the-counter medical food (Ocufolin) for 6 months.
NCT01013077
The purpose of this study is to investigate how the addition of a new emulsion artificial tear to the tear layer of dry eye and normal patients affects aberrometry, contrast sensitivity, and reading ability over time. Previous studies have indicated that daily use of artificial tears over a two week period decreases the short term affect of drop application on aberrometry and contrast sensitivity measurements. The present study will examine the effects of 4 weeks of artificial tear use to determine when the responses stabilize.
NCT02585414
Dry eye syndrome (DES) is a highly prevalent ocular condition with potential severe consequences for affected patients. DES can be either caused by decreased tear production or increased tear evaporation, both leading to an instable tear film. Despite many efforts, generally accepted methodologies to diagnose, assess the severity and monitor DES are still lacking. Moreover, widely used clinical methods such as tear break up time (BUT), fluorescein staining of the cornea or Schirmer test only poorly reflect patients´ complains. One of the main problems in the diagnosis and treatment of DES is that the most critical component - the tear film itself - is difficult to characterize. The development of new ultra-high resolution optical coherence tomography systems allows now for the direct visualization of the human tear film and for the non-invasive in-vivo measurement of tear film thickness (TFT). The investigators could recently show that this system provides excellent reproducibility and is able to assess even subtle changes in TFT induced by therapeutic interventions. However, to which extent tear film thickness is associated with other standard clinical measures of DES is currently unknown. In the present study, the investigators set out to test the hypothesis that ocular TFT is a new and good surrogate parameter for the assessment of the severity of DES. Consequently, the aim of the study presented in this protocol is to investigate whether and if so, to what extent clinical signs of DES and reported symptoms are reflected in ocular TFT. For this purpose, a cross sectional study in healthy subjects and patients with DES will be performed. This should allow the investigators to more specifically characterize the role of the tear film in DES and to assess whether measurement of TFT with OCT can be a promising surrogate parameter for the diagnosis and the follow up of DES.
