Abstract
Dry eye disease (DED) can arise from a variety of factors, including inflammation, meibomian gland dysfunction (MGD), and neurosensory abnormalities. Individuals with DED may exhibit a range of clinical signs, including tear instability, reduced tear production, and epithelial disruption, that are driven by different pathophysiological contributors. Those affected often report a spectrum of pain and visual symptoms that can impact physical and mental aspects of health, placing an overall burden on an individual's well-being. This cumulative impact of DED on an individual's activities and on society underscores the importance of finding diverse and effective management strategies. Such management strategies necessitate an understanding of the underlying pathophysiological mechanisms that contribute to DED in the individual patient. Presently, the majority of approved therapies for DED address T cell-mediated inflammation, with their tolerability and effectiveness varying across different studies. However, there is an emergence of treatments that target additional aspects of the disease, including novel inflammatory pathways, abnormalities of the eyelid margin, and neuronal function. These developments may allow for a more nuanced and precise management strategy for DED. This review highlights the recent pharmacological advancements in DED therapy in the United States. It discusses the mechanisms of action of these new treatments, presents key findings from clinical trials, discusses their current stage of development, and explores their potential applicability to different sub-types of DED. By providing a comprehensive overview of products in development, this review aims to contribute valuable insights to the ongoing efforts in enhancing the therapeutic options available to individuals suffering from DED.

Abstract
Dry eye disease (DED) incidence is continuously growing, positioning it to become an emergent health issue over the next few years. Several topical treatments are commonly used to treat DED; however, reports indicate that only a minor proportion of drug bioavailability is achieved by the majority of eye drops available on the market. In this context, enhancing drug ability to overcome ocular barriers and prolonging its residence time on the ocular surface represent a new challenge in the field of ocular carrier systems. Therefore, research has focused on the development of multi-functional nanosystems, such as nanoemulsions, liposomes, dendrimers, hydrogels, and other nanosized carriers. These systems are designed to improve topical drug bioavailability and efficacy and, at the same time, require fewer daily administrations, with potentially reduced side effects. This review summarizes the different nanotechnologies developed, their role in DED, and the nanotechnology-based eyedrops currently approved for DED treatment.

Abstract
Dry eye syndrome (DES) is a prevalent and multifactorial disease that leads to a self-perpetuating cycle of inflammation and damage to the ocular surface. This results in symptoms such as redness, burning, and blurred vision, which can negatively affect a patient's quality of life. While treatments are available to manage DES, they only temporarily relieve symptoms. Furthermore, long-term use of certain medications can cause harm to the ocular surface. Therefore, there is a need for safer and effective treatments for DES. This review highlights the latest advancements in DES therapy, providing valuable insights into ongoing efforts to improve patient outcomes.

Abstract
PURPOSE To report the heterogeneity in methodology of clinical trials submitted to the US Food and Drug Administration (FDA) for approval of topical dry eye treatments. DESIGN Comparative analysis of clinical trials' methods. METHODS We reviewed the online, publicly available FDA database, application review files, ClinicalTrials.gov registry records, and journal articles for each FDA-approved topical dry eye treatment. For each trial, we extracted information about the study, patient demographics, treatment names and doses, sample size in each arm, and the measurement instrument in a systematic fashion. RESULTS Fourteen trials were included that assessed 5 topical treatments for dry eye (cyclosporine 0.05%, cyclosporine 0.09%, lifitegrast 5%, and loteprednol 0.25% eye drops and varenicline 0.03-mg nasal spray). Median treatment duration was 12 weeks (range, 2-24 weeks). In all trials, treatments, including varying concentrations of the same treatment, were compared with vehicle. Twelve trials (85.7%) evaluated a primary clinician-measured clinical sign, and 10 trials (71.4%) evaluated a primary patient-reported symptom. Corneal staining was the most frequently evaluated clinical sign primary outcome, reported in half (6 of 12) of the trials, and was graded using 4 different scoring systems. Conjunctival staining, conjunctival hyperemia, and tear production were each measured using 2 different scoring systems. Ocular discomfort, the only patient-reported symptom primary outcome, was measured using 5 different instruments. CONCLUSION A variety of outcome measures were used in these clinical trials. Clinically meaningful dry eye outcome measures and standardized measurements can optimize the assessment of and comparison of therapeutic benefits.

Abstract
Dry eye disease (DED) has been found to occur at a higher prevalence in individuals with glaucoma than in individuals without glaucoma. The relationship between glaucoma and DED may be, in part, a result of glaucoma therapy. Greater number of antiglaucoma medications used and greater number of antiglaucoma eyedrops instilled per day have been associated with ocular surface disease in patients with glaucoma. Use of antiglaucoma medication has also been associated with higher levels of ocular surface inflammatory markers and ocular surface alterations. There is evidence to suggest that antiglaucoma medications with preservatives and, to some extent, antiglaucoma medication formulations without preservatives may contribute to ocular surface signs and symptoms. Trabeculectomy for glaucoma has also been associated with ocular surface signs related to DED; however, there may be benefits of trabeculectomy and other procedures for glaucoma due to reduced use of antiglaucoma medications. Patients with glaucoma with ocular surface disease have been found to have greater ocular surface symptoms, poorer vision-related quality of life, and poorer antiglaucoma medication adherence compared with patients with glaucoma without ocular surface disease. Because of the potential negative impact of DED on patients with glaucoma, patients with glaucoma may benefit from evaluation for DED. Management of DED in patients with glaucoma may include modifications to antiglaucoma medications and use of treatments for DED.

Prospective Assessment of Loteprednol Etabonate 0.25% for Prevention of Immunologic Rejection After Descemet Membrane Endothelial Keratoplasty in Eyes With Fuchs Dystrophy. Cornea 2023:00003226-990000000-00381. [PMID: 37733966 DOI: 10.1097/ico.0000000000003398] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/17/2023] [Accepted: 08/23/2023] [Indexed: 09/23/2023]
Abstract
PURPOSE The purpose of this study was to assess off-label use of loteprednol etabonate 0.25% ophthalmic suspension for prevention of immunologic rejection after Descemet membrane endothelial keratoplasty (DMEK). METHODS This prospective, open-label study enrolled 70 eyes of 70 participants without preexisting glaucoma 1 month after DMEK. Participants used topical loteprednol 0.25% 4 times daily for 2 months, tapered by 1 drop/month to once daily use, and continued use through 1 year after DMEK. Main outcomes were rate of intraocular pressure (IOP) elevation (defined as a relative increase of ≥10 mm Hg over the pretransplant IOP) and rate of initial allograft rejection episodes. The results were compared with historical data using the log-rank test. RESULTS All participants had Fuchs dystrophy, and 40 of 70 (57%) were female. None (0%) experienced an immunologic graft rejection episode, matching the previously reported efficacy of prednisolone acetate 1% suspension and loteprednol 0.5% gel (both 0% incidence). One study eye developed IOP elevation 3 months after DMEK (cumulative risk 1.5%). Compared with historical data, this was similar to the risk with loteprednol 0.5% gel (4%, P = 0.36) and significantly lower than the risk with prednisolone 1% suspension (18%, P = 0.0025). Two participants (3%) complained of instillation site discomfort, consistent with the 5% rate reported on package labeling. CONCLUSIONS Loteprednol 0.25% suspension, approved for short-term treatment of dry eyes, effectively prevented immunologic rejection episodes with minimal risk of IOP elevation when used from 1 month until 12 months after DMEK in patients without preexisting glaucoma.

Abstract
Loteprednol etabonate (LE) is a topical corticosteroid that uses inflammatory conditions of the eye. It has a low ocular bioavailability and side effects such as corneal disorder, eye discharge, and ocular discomfort. Therefore, it was decided to select the delivery systems, which are solid lipid nanoparticles (SLN), nanostructured lipid carriers (NLC), and nanoemulsion (NE). Design of experiments (DoE) of SLN, NLC, and NE formulations were formulated by using the quality by design (QbD) approach. Precirol® ATO 5 and oleic acid were used as solid and liquid lipids, respectively, in SLN, NLC, and NE formulations. Physiochemical characterization was performed on the formulations. The optimized formulations' inflammatory effects have been appraised on human corneal epithelial cells employing the ELISA test. Physicochemical characterization studies and inflammatory effects were appraised. The sizes of optimized formulations of SLN, NLC, and NE were 86.19 nm, 82.38 nm, and 126.35 nm, respectively, with minimum polydispersity. The release behavior of the formulations is composed of both diffusion and erosion. ELISA test results proved that the formulations significantly reduced IL-1 and IL-6 levels (p < 0.05). D-optimal mixture experimental design allowed us to develop the most precise formulations of SLN, NLC, and NE. Furthermore, the optimized formulations could be promising candidates for treating an inflammation-based corneal disease of the eye.

Abstract
Purpose: A new class of ocular steroids designed to mitigate steroid-induced intraocular pressure (IOP) elevation while maintaining anti-inflammatory activity was developed. Herein is described the discovery and preclinical characterization of ROCK'Ster compound 1. Methods: Codrugs consisting of a Rho kinase inhibitor (ROCKi) and a corticosteroid were synthesized. Compounds were initially screened in vitro for ROCKi activity and anti-inflammatory activity against the proinflammatory interleukin 23 and bacterial lipopolysaccharide (LPS) pathways. Selected compounds were then screened for solubility, chemical stability, and ex vivo corneal metabolism. Lead compound 1 was evaluated for IOP lowering in the Dutch Belted rabbit and for anti-inflammatory efficacy in both a postcataract surgery model and an allergic eye disease (AED) mouse model. Results: Several ROCK'Sters were found to be potent inhibitors of ROCK (Kis < 50 nM), have high anti-inflammatory activity in vitro (IC50s < 50 nM), display sufficient stability in topical ophthalmic formulations, and have a moderate rate of corneal metabolism. Compound 1 (0.1% and 0.25%, quater in die [QID]-4 times a day) demonstrated IOP-lowering capability without inducing hyperemia in our rabbit model. When compared with the marketed steroids, Durezol® and Pred Forte®, compound 1 (0.1%, 0.25%) demonstrated noninferiority in clinical scoring in a rabbit model of inflammation after surgery. In addition, anti-inflammatory outcomes were observed with compound 1 (0.1%) relative to Lotemax® or vehicle control in an AED mouse model. Conclusion: ROCK'Ster compound 1 is a novel compound suitable for topical ocular dosing that possesses IOP-lowering capability along with similar anti-inflammatory activity compared with marketed steroids.
