Here, we outline how to identify various stages of age-related macular degeneration including geographic atrophy (GA) by examining optimal management scenarios implicating various ECPs and reviewing treatment considerations for patients with GA. Early identification of GA will lead to optimal patient outcomes, while a standardized management scenario will reduce clinical burden among ECPs treating patients with GA.Keywords: age-related macular degeneration, patient care, retina, treatment

Twelve ocular surface disease experts comprised the Demodex Expert Panel on Treatment and Eyelid Health (DEPTH). They completed a live roundtable discussion in addition to 3 surveys consisting of scaled, open-ended, true/false, and multiple-choice questions pertaining to the treatment of DB. Consensus for scaled questions using a 1 to 9 Likert scale was predefined as median scores of 7– 9 and 1– 3. For other question types, consensus was achieved when 8 of 12 panelists agreed.Results: The experts agreed that an effective therapeutic agent for treatment of DB would likely decrease the necessity of mechanical intervention, such as lid scrubs or blepharoexfoliation (Median = 8.5; Range 2– 9). When treating DB, panelists believed that collarettes serve as a surrogate for mites, and that eliminating or reducing collarettes should be the main clinical goal of treatment (Median = 8; Range 7– 9). The panelists would treat patients with at least 10 collarettes, regardless of other signs or symptoms and agreed that DB can be cured, but there is always the possibility for a reinfestation (n = 12). There was also consensus that collarettes, and therefore mites, are the primary treatment target and the way by which clinicians can monitor patient response to therapy (Median = 8; Range 7– 9).Conclusion: Expert panelists achieved consensus on key facets of DB treatment. Specifically, there was consensus that collarettes are pathognomonic for DB, that DB patients with > 10 collarettes should be treated even in the absence of symptoms, and that treatment efficacy can be tracked by collarette resolution. By increasing awareness about DB, understanding the goals of and monitoring treatment efficacy, patients will receive better care and, ultimately, better clinical outcomes.Keywords: collarettes, cylindrical dandruff, ocular surface disease, eyelid disease

If uncorrected or under-corrected, presbyopia can significantly impact patients’ quality of life. Presbyopia represents an area of considerable unmet need due to its rising prevalence worldwide as the population ages, the high proportion of under-treated individuals in some parts of the world, and the limitations of currently available corrective methods. Progressive or bifocal spectacles are associated with peripheral blur, a restricted visual field and impaired depth perception, which have been linked to an increased risk of falls in the elderly. Contact lens options can be difficult to maintain due to the development of age-related dry eye symptoms and reduced manual dexterity. Other corrective methods involve surgical interventions that modify the optics of the cornea, replace the crystalline lens, or attempt to restore active accommodation. While patients undergoing surgery report satisfactory outcomes post-operatively, many of them eventually require reading glasses. Non-invasive therapies with novel mechanisms of action are currently being investigated; these include miotic agents and UNR844, a lipoic acid choline ester. In this narrative review, available evidence on presbyopia prevalence, quality of life impact and risk factors are described, with a focus on observational studies in non-clinical settings. The diagnosis pathway and patient journey in presbyopia are outlined, and various treatment options are analyzed. The data reviewed herein reveals significant gaps in the provision of vision correction for this common condition, with a paucity of effective, non-invasive treatment options broadly accessible to presbyopic individuals.Keywords: presbyopia, epidemiology, patient characterization, vision correction, pharmacological therapies

The ORION-1 trial evaluated the long-term safety and efficacy of PMOS in a glaucomatous, presbyopic population.Patients and Methods: In this randomized, double-masked, multi-center, placebo-controlled, multiple-dose Phase 2b trial, 39 patients with elevated IOP were randomized to receive one evening dose of study medication or placebo for 14 days. The primary outcome measure was mean change in diurnal IOP, and the key secondary outcome measures included changes in PD, distance-corrected near visual acuity (DCNVA), and conjunctival hyperemia.Results: Use of 1% PMOS did not lead to a statistically significant decrease in diurnal IOP compared to placebo (P = 0.89) but trended toward a greater decrease in patients with lower IOP baselines. PMOS produced a statistically significant mean 20% PD reduction under both photopic and mesopic conditions that was sustained for 36 hours post-dosing. A statistically significant number of patients with PMOS compared to placebo demonstrated ≥ 1 line of improvement in photopic DCNVA at day 8 (P = 0.0018), day 15 (P = 0.0072), and day 16 (P = 0.0163), with a trend for 2- and 3-line improvements at all time points. There was no statistical difference in conjunctival hyperemia compared to placebo.Conclusion: Although mean IOP was not lowered significantly, daily evening dosing of 1% PMOS was found to be well tolerated with no daytime conjunctival redness and demonstrated improvement in DCNVA with sustained PD reduction in a glaucomatous and presbyopic population. Smaller pupil size can have beneficial effects in improving symptoms of presbyopia and DLD, which will be the focus of further studies.Keywords: IOP, presbyopia, night vision disturbances, dim light vision disturbances, pupil diameter, ORION-1

Laura M Periman,1 Francis S Mah,2 Paul M Karpecki3 1Periman Eye Institute, Seattle, WA, USA; 2Scripps Health, La Jolla, CA, USA; 3Kentucky Eye Institute, Lexington, KY, USACorrespondence: Laura M PerimanPeriman Eye Institute, Seattle, WA, USAEmail dryeyemaster@gmail.comAbstract: Dry eye disease (DED) is a multifactorial disease of the ocular surface and tear film that has gained awareness as a public health problem. Characteristics of DED include tear film instability, hyperosmolarity, and ocular surface inflammation, which can occur independently or may be a sequela of numerous ocular diseases, ocular surgery or contact lens wear. Much has been learned about the impact of the disease to help affected individuals who report symptoms of poor vision, pain, and tearing. Recently, new research highlights the importance of the role of ocular surface inflammation and damage in DED—leading to a vicious cycle of inflammation as well as loss of tear film homeostasis. DED immunopathophysiology is characterized by four stages: initiation, amplification, recruitment, and re-initiation. Cyclosporine is proven to be a valuable ophthalmic therapeutic for DED through its immunomodulatory actions and regulation of the adaptive immune response. Cyclosporine mechanism of action is well described in the published literature and the myriad of benefits in all four stages lend a broad-based immunomodulatory function particularly suitable for addressing DED. Furthermore, cyclosporine has unique goblet cell density improvement capabilities as well as anti-apoptotic properties. Topical formulations of cyclosporine are centered around addressing the highly lipophilic nature of the molecule. The poor aqueous solubility of cyclosporine traditionally presented technical challenges in drug delivery to the ocular surface. Newer formulations such as cationic emulsions and nanomicellar aqueous solutions address formulation, tissue concentration, and drug delivery challenges.Keywords: dry eye disease, cyclosporine A, emulsion, OTX-101, keratoconjunctivitis sicca

Eligible patients had continuous medical and pharmacy benefits in the 12 months pre- and post-index periods, and no prior use of the index medication. The proportion of days covered (PDC), adherence, non-persistence, discontinuation, and switching were examined over the 12-month post-index period.Results: This study included 6537 CYC and 3235 LIF patients. The adherence rate was 5.9% for CYC and 9.7% for LIF; the median PDC was 0.3 for both cohorts. Overall, 70.8% of CYC and 64.4% of LIF patients discontinued treatment with median days to discontinuation of 89 and 29, respectively. Non-persistence was 7.1% for CYC and 6.8% for LIF (median days to discontinuation: 89 and 105). In addition, 5.0% switched from CYC to LIF, and 9.6% switched from LIF to CYC over the post-index period.Conclusion: Over 60% of DED patients discontinued treatment within 12 months of initiation; the median time to discontinuation was 3 months for CYC and 1 month for LIF. Although this analysis did not capture the reasons why patients discontinued treatment, the results demonstrate there likely exists a significant unmet need amongst DED patients.Keywords: dry eye disease, adherence, persistence, cyclosporine ophthalmic emulsion, lifitegrast ophthalmic solution

Patients and methods: Healthy volunteers ≥18 years of age were recruited for participation in this phase 1, open-label, single-center, single-arm, study. Subjects received one drop of OTX-101 0.09% in each eye every 12 hours for 7 days, and once on day 8. Blood samples were collected predose, and 0.25, 0.5, 1, 2, 4, 8, and 12 hours post-first dose on day 1 and day 8. CsA levels in whole blood samples were analyzed using liquid chromatography-tandem mass spectrometry. Pharmacokinetic parameters (maximal whole blood concentration [Cmax, ng/mL], time to Cmax [Tmax, hours]), and area under the concentration-time curve from 0 to the last measurement [AUC(0–t), h·ng/mL]) were calculated using noncompartmental analysis. Safety assessments included subject-reported adverse events (AEs), vital signs, visual acuity, intraocular pressure measurement, biomicroscopy, and direct ophthalmoscopy. Results: A total of 16 subjects were enrolled; 15 subjects completed the study. Blood sample analysis indicated limited systemic exposure to CsA; three subjects had a CsA concentration greater than or equal to the lower limit of quantitation (LLOQ) on day 1; only four subjects had three consecutive CsA concentration measurements ≥LLOQ on day 8; the mean±SD for Cmax was 0.17±0.02 ng/mL, Tmax was 1.5±0.58 hours, and AUC(0–t) was 0.53±0.06 h·ng/mL. Three subjects reported three AEs (eye pain, eye pruritis, and eye irritation) during the study. No clinically significant changes in the safety assessments were noted. Conclusion: The OTX-101 formulation was well tolerated. Systemic exposure to CsA was negligible in healthy volunteers after twice-daily ocular administration. No evidence for systemic accumulation of CsA was observed. Keywords: dry eye disease, cyclosporine, pharmacokinetic, systemic exposure

Forty-two subjects were enrolled and received 1–2 drops twice daily of Retaine™ beginning at the first visit (day 1) and ending at the second visit. Subjects were instructed to complete a symptomatology diary twice daily prior to drop instillation through the morning of the second visit. Ocular sign and symptom assessments, visual acuity procedures, and comfort assessments were conducted during both visits. A statistically significant reduction was observed in mean breakup area on the second visit between the predose time and the postdose time (P=0.026). On the second visit, subjects had significantly less corneal fluorescein staining in the superior (P=0.002), central (P=0.017), corneal sum (P=0.011), and all ocular regions combined (P=0.038) than on the first visit. On the second visit, statistically significant reductions in dryness (P

Introduction: Chronic ocular surface pain (COSP) is described as a persistent, moderate-to-severe pain at the ocular surface lasting more than 3 months. Symptoms of COSP have a significant impact on patients' vision-dependent activities of daily living (ADL) and distal health-related quality of life (HRQoL). To adequately capture patient perspectives in clinical trials, patient-reported outcome (PRO) measures must demonstrate sufficient evidence of content validity in the target population. This study aimed to explore the patient experience of living with COSP and evaluate content validity of the newly developed Chronic Ocular Pain Questionnaire (COP-Q) for use in COSP clinical trials., Methods: Qualitative, combined concept elicitation (CE) and cognitive debriefing (CD) interviews were conducted with 24 patients experiencing COSP symptoms in the USA. Interviews were supplemented with real-time data collection via a daily diary app task in a subset of patients (n = 15) to explore the day-to-day patient experience. Three healthcare professionals (HCPs) from the USA, Canada, and France were also interviewed to provide a clinical perspective. CE results were used to further inform development of a conceptual model and to refine PRO items/response options. CD interviews assessed relevance and understanding of the COP-Q. Interviews were conducted across multiple rounds to allow item modifications and subsequent testing., Results: Eye pain, eye itch, burning sensation, eye dryness, eye irritation, foreign body sensation, eye fatigue, and eye grittiness were the most frequently reported symptoms impacting vision-dependent ADL (e.g., reading, using digital devices, driving) and wider HRQoL (e.g., emotional wellbeing, social functioning, work). COP-Q instructions, items, and response scales were understood, and concepts were considered relevant. Feedback supported modifications to instruction/item wording and confirmed the most appropriate recall periods., Conclusions: Findings support content validity of the COP-Q for use in COSP populations. Ongoing research to evaluate psychometric validity of the COP-Q will support future use of the instrument in clinical trial efficacy endpoints., (© 2024. The Author(s).)

Dry eye disease (DED) is a common condition in which tear film abnormalities result in a damaging cycle of tear hyperosmolarity, desiccating stress, inflammation, and ocular surface injury. In a healthy tear film, meibum produced by the meibomian glands forms a lipid layer that stabilizes the tear film and protects against aqueous tear evaporation. Excessive tear evaporation due to a deficient lipid layer is believed to be the most common cause of DED, and most evaporative DED is associated with meibomian gland dysfunction (MGD); this highlights the pathophysiologic importance of the dysfunctional tear lipid layer. Current treatments for DED may be used to supplement hyperosmolar aqueous tears, lubricate the ocular surface, increase meibum flow, decrease inflammation, promote tear production, or otherwise decrease clinical signs of ocular surface damage and/or improve symptoms. Until now, no prescription eye drop has directly addressed the excessive evaporation that occurs in most patients with DED. Perfluorohexyloctane (PFHO) ophthalmic solution (MIEBO™; Bausch + Lomb) is a preservative-free eye drop that has demonstrated the ability to form a long-lasting barrier that inhibits evaporation in preclinical studies. FDA approval of PFHO was based on results from 2 pivotal clinical trials (GOBI [NCT04139798] and MOJAVE [NCT04567329]) in patients with DED and clinical signs of MGD which demonstrated consistent improvements in both signs and symptoms of disease, with a safety profile similar to that of saline eye drops. PFHO is the first and only FDA-approved eye drop that directly targets tear evaporation in patients with DED, thereby promoting ocular surface healing and providing symptomatic relief.

Background/aims: With a paradigm shift in geographic atrophy (GA) treatments now available, establishing consensus on the identification and diagnosis of the disease along with considerations for management of patients with GA will assist eye care professionals (ECP) in their day-to-day practices, leading to improved patient outcomes., Methods: A modified Delphi panel process (Geographic Atrophy Management Consensus) consisting of three total surveys and one virtual live meeting held between survey 2 and survey 3. Data were collected from July to October 2022. Participants included expert members of the eye care community that have demonstrated outstanding leadership among peers: a steering committee with three ECPs and a 15-member panel divided between five optometrists, five comprehensive ophthalmologists and five retina specialists. Consensus on statements related to the management of patients with GA was calculated using the RAND/UCLA Appropriateness Method., Results: At the conclusion of the third survey, consensus was reached on 91% of the 77 statements. Critical consensus topics include: (1) optical coherence tomography as the favoured method to diagnose and monitor GA, (2) preferred practice patterns regarding referral of patients to retina specialists and (3) treatment criteria given the advent of emerging therapeutics for GA., Conclusions: Generating awareness of early signs of disease development, progression and identifying the best tools to evaluate GA establishes ideal management and referral strategies. Given the paradigm shift in GA management driven by approved therapies, coupled with the fact that the disease is progressive resulting in devastating vision loss, these strategies are critical to ensure best overall outcomes., Competing Interests: Competing interests: PKK, CDR, YM, EY, TK, NK and MTD have served as consultants for IVERIC bio.

Background: Twelve ocular surface disease experts convened to achieve consensus about Demodex blepharitis (DB) using a modified Delphi panel process., Methods: Online surveys were administered using scaled, open-ended, true/false, and multiple-choice questions. Consensus for questions using a 1 to 9 Likert scale was predefined as median scores of 7-9 and 1-3. For other question types, consensus was achieved when 8 of 12 panellists agreed. Questions were randomized, and results of each survey informed the following survey., Results: Twelve practitioners comprised the Demodex Expert Panel on Treatment and Eyelid Health (DEPTH). Following 3 surveys, experts agreed that DB is chronic (n = 11) and recurrent (n = 12) and is often misdiagnosed. Consensus was achieved regarding inflammation driving symptoms (median = 7; range 7-9), collarettes as the most common sign (n = 10) and pathognomonic for DB (median = 9; range 8-9), and itching as the most common symptom (n = 12). Panellists agreed that DB may be diagnosed based on collarettes, mites, and/or patient symptoms (n = 10) and felt that patients unresponsive to typical therapies should be evaluated for DB (n = 12). Consensus about the most effective currently available OTC treatment was not reached., Conclusions: The Delphi methodology proved effective in establishing consensus about DB, including signs, symptoms, and diagnosis. Consensus was not reached about the best treatment or how to grade severity. With increased awareness, eyecare practitioners can offer DB patients better clinical outcomes. A follow-up Delphi panel is planned to obtain further consensus surrounding DB treatment., (© 2023. The Author(s).)

Use of a combination corticosteroid and antibiotic in a single formulation is common in the treatment of ocular inflammatory conditions for which corticosteroid therapy is indicated and there exists a risk of superficial bacterial infection. Loteprednol etabonate (LE) is a corticosteroid engineered to maintain potent anti-inflammatory activity while minimizing the risk of undesirable class effects of corticosteroids, such as elevated intraocular pressure and cataract. Tobramycin is a broad-spectrum aminoglycoside antibiotic that is considered generally safe and well tolerated. An ophthalmic suspension combining LE 0.5% and tobramycin 0.3% (LE/T) is approved in the US and several other countries. Use of a combination therapy increases convenience, which may promote patient adherence. A systematic literature review was conducted to examine the efficacy and safety of LE/T for ocular inflammatory conditions within the scope of its labeled indications. Results of published studies indicate that LE/T is effective in the treatment of blepharokeratoconjunctivitis in adults, with similar efficacy as dexamethasone 0.1%/tobramycin 0.3%, but is associated with a lower risk of clinically significant increases in intraocular pressure as demonstrated in both efficacy and safety studies and studies with healthy volunteers. Furthermore, studies in children with blepharitis or blepharoconjunctivitis indicate LE/T was well tolerated in this population, although efficacy vs vehicle was not demonstrated, potentially due to improvements in all groups overall and/or limited sample size. Separately, tobramycin demonstrated potent in vitro activity against most bacterial species associated with blepharitis. In conclusion, published data demonstrate the utility of LE/T for the treatment of the various clinical manifestations of blepharokeratoconjunctivitis in adults., (© 2021. The Author(s).)

Dry eye disease is a common but underdiagnosed disorder in the United States, and its prevalence is likely to increase as the nation's population ages. Although still regarded as little more than a nuisance by many clinicians and payers alike, dry eye disease is known to have both clinical consequences for ocular health and effects on vision-related quality of life in many people, impairing their ability to function well in vocational and social settings. Pharmaceutical treatments consist mainly of over-the-counter ocular lubricants ("artificial tears") and a few prescription drugs that address the inflammatory component of dry eye disease through immunomodulation and/or inhibition of T-cell activity. In September 2020, Oyster Point Pharma, Inc (Oyster Point Pharma), convened a panel-consisting of 7 managed care executives with experience in management of dry eye disease treatments and 2 eye care practitioners with expertise in dry eye disease-to discuss how the growth of knowledge about dry eye disease in the past 2 decades has altered their thinking about and approach to dry eye disease, as well as how they would like to see the field advance. They pointed to an existing unmet need in knowledge and therapeutics that can address the underlying causes of dry eye disease. Oyster Point Pharma supported the authorship of this article; the authors were members of the panel, and all panelists were compensated by Oyster Point Pharma. This article provides an overview of dry eye disease and summarizes the panel discussion.

Bacterial conjunctivitis, commonly known as pink eye, is demographically unbiased in its prevalence and can be caused by a variety of aerobic and anaerobic bacteria. Timely empiric treatment with a broad-spectrum anti-infective, such as a topical fluoroquinolone, is critical in preventing potentially irreversible ocular damage. However, the rise in ocular methicillin- resistant Staphylococcus aureus isolates and the patterns of fluoroquinolone resistance for patients with other ocular bacterial infections mandate the need for new agents targeted for ocular use. Besifloxacin, a novel broad-spectrum fluoroquinolone, is approved for the treatment of bacterial conjunctivitis. It has a uniquely balanced dual-targeting activity that inhibits both DNA gyrase and topoisomerase IV and is associated with a lower incidence of resistance development. Besifloxacin is not marketed in other formulations, ensuring that its exposure is limited to bacterial populations in and around the eye. This specifically precludes any bacterial exposure to besifloxacin resulting from systemic use, which further reduces the likelihood of emergence of bacterial resistance. In vitro, besifloxacin has demonstrated equivalent or superior activity compared with other commonly used topical antibiotics. In clinical trials, besifloxacin has consistently demonstrated efficacy and safety in the treatment of patients with bacterial conjunctivitis. Besifloxacin is considered safe and is well tolerated with no observed contraindications.
