ABSTRACT

PURPOSE: The academic success of ophthalmology fellows may be significantly impacted by their research engagement. Evaluating the research activity of fellows by subspecialty may provide insight into trends useful for prospective applicants. The objective of this study was to assess the research activity of ophthalmology fellows in the year 2023. METHODS: Ophthalmology fellowship programs were compiled using the Association of University Professors of Ophthalmology and the American Society of Ophthalmic Plastic and Reconstructive Surgery websites. Program subspecialties were categorized as: Cornea and External Disease [CED]; Cornea, External Disease, and Refractive Surgery [CEDRS]; Glaucoma; Medical Retina [MR]; Neuro-Ophthalmology [NO]; Oculoplastics; Pediatric Ophthalmology [PO]; Surgical Retina [SR]; Uveitis; and Other. "Other" consisted of Oncology, Pathology, combined Oncology and Pathology fellowships. We identified current fellows using publicly available online information. Programs and fellows that did not have information available were excluded. Total publications, Hirsch index (h-index), and weighted-relative citation ration (w-RCR) were utilized as measures of research output, while total citations and mean-RCR (m-RCR) served as proxies for research impact. Duration of publishing was calculated using the years of the oldest and most recent publications. Statistical analysis was performed using Kruskal-Wallis H tests with an alpha value of .05. RESULTS: A total of 373 fellows from 229 programs met our inclusion criteria. More than half of fellows were men (54.4%), and the most common degree type was MD (93.0%). Across all subspecialties, the median h-index was 3.0 (IQR = 4), m-RCR was .9 (IQR = 1.2) and w-RCR was 3.2 (IQR = 9.8). The median number of publications was six (IQR = 10, with 34 citations (IQR = 110) and 4 years of publishing (IQR = 6). We observed significant differences in h-index (p = .038), total publications (p < .001), and w-RCR (p = .028) by subspecialty. CONCLUSION: We observed significant differences in research output, but no differences in research impact by subspecialty. Overall, Uveitis and Oculoplastics fellows had higher research activity, while Medical Retina and Other fellows had the lowest. This data is pertinent to better understand the landscape of ophthalmology fellowship applications.

ABSTRACT

Newly approved treatments for patients with geographic atrophy are changing the treatment paradigm, highlighting the need for eye care providers (ECPs) to have a set of recommendations on how to best manage GA patients. 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.

ABSTRACT

PURPOSE: The purpose of this study was to evaluate the pharmacogenomics of response to topical ocular tumor necrosis factor α (TNFα) inhibitor licaminlimab in patients with DED. METHODS: Three single-nucleotide polymorphisms (SNPs) associated with Sjögren syndrome, 3 in the TNFα gene and 1 in the TNF receptor 1 (TNFR1) gene, were assessed for association with response to licaminlimab in participants from a randomized, vehicle-controlled, Phase 2 study in which adults with DED and severe ocular discomfort persisting despite treatment with artificial tears received licaminlimab or vehicle for 6 weeks. Response was assessed for change from baseline in Global Ocular Discomfort score at Day 29 of treatment. The pharmacogenomic analysis was a prospectively specified exploratory objective of the study. mRNA expression for TNFα, interleukin (IL) 1ß, and IL8 in conjunctival epithelium cells was determined. The relationship between SNPs and response to licaminlimab was assessed using a mixed model repeated measures analysis. RESULTS: SNP rs1800693 in the TNFR1 gene showed a significant effect on response to licaminlimab (P < 0.0001, initial association test); no effect was seen for any of the other SNPs tested. The CC genotype of rs1800693 was associated with much greater response to licaminlimab than the CT or TT genotypes: LS mean changes from baseline to Day 29 in Global Ocular Discomfort score were -29.5, -0.09, and -3.90, in patients with the CC, CT, and TT genotypes, respectively (P < 0.0001). No significant effect was observed in vehicle-treated patients. Improvements from baseline were seen in 3/4 licaminlimab-treated participants with the CC genotype. Conjunctival epithelium cell levels of mRNA for TNFα, IL1ß, and IL8 decreased from baseline in participants with the CC genotype, but not with the CT or TT genotypes. Between-genotype differences in mRNA levels were not observed in participants receiving vehicle. CONCLUSIONS: The CC genotype of rs1800693, relatively common in patients with DED, was strongly associated with response to licaminlimab and decreased inflammatory cytokine gene expression in ocular surface cells during treatment. This study is one of the first to our knowledge to investigate pharmacogenomics in the treatment of DED.

ABSTRACT

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.

ABSTRACT

Purpose: To evaluate clinical efficacy and patient preference for a dropless treatment regimen compared to conventional topical therapy in patients undergoing cataract surgery. Patients and Methods: In this prospective, contralateral eye study, patients with bilateral cataract were randomized to receive either intracanalicular dexamethasone insert, intracameral phenylephrine 1%/ketorolac 0.3%, and intracameral moxifloxacin (50 µg) (study group) or topical moxifloxacin 0.5%, ketorolac 0.5%, and prednisolone acetate 1.0% QID (control group). The second eye underwent cataract surgery 2 weeks later and was treated with the opposite treatment. All patients were evaluated at Days 1, 7, 14, 28, and 3 months. The primary outcome measure was postoperative ocular pain. Secondary outcomes included summed ocular inflammation score (SOIS; the sum of the mean anterior chamber cells and anterior flare score), the patient preference for medication protocol between the two eyes, and patient out-of-pocket cost of medications. Safety outcome measures included CDVA, intraocular pressure, central retinal thickness (CRT), and the incidence of reported AEs. Results: The proportion of patients with no pain was similar in both groups at all postoperative visits (p>0.05). No statistically significant difference in SOIS score was observed between the two groups at any visit. A strong majority of the patients (94.7%) preferred the study eye's dropless regimen over the control eye's conventional topical therapy regimen. No statistically significant difference in mean intraocular pressure (IOP) was observed at any postoperative visit, except at Week 1. The mean CDVA was also similar in both groups at all postoperative visits (p>0.05). The postoperative mean CRT was comparable between the two groups. Conclusion: A dropless treatment regimen is as effective as topical eyedrop administration. A higher proportion of patients who underwent bilateral cataract surgery preferred the dropless treatment regimen over the patient-administered eye drop regimen.

ABSTRACT

PURPOSE: To evaluate the safety and efficacy of lotilaner ophthalmic solution 0.25% compared with vehicle for the treatment of Demodex blepharitis. DESIGN: Prospective, randomized, double-masked, vehicle-controlled, multicenter, phase 3 clinical trial. PARTICIPANTS: Four hundred twelve patients with Demodex blepharitis were assigned randomly in a 1:1 ratio to receive either lotilaner ophthalmic solution 0.25% (study group) or vehicle without lotilaner (control group). METHODS: Patients with Demodex blepharitis treated at 21 United States clinical sites were assigned either to the study group (n = 203) to receive lotilaner ophthalmic solution 0.25% or to the control group (n = 209) to receive vehicle without lotilaner bilaterally twice daily for 6 weeks. Collarettes and erythema were graded for each eyelid at screening and at all visits after baseline. At screening and on days 15, 22, and 43, 4 or more eyelashes were epilated from each eye, and the number of Demodex mites present on the lashes was counted with a microscope. Mite density was calculated as the number of mites per lash. MAIN OUTCOME MEASURES: Outcome measures included collarette cure (collarette grade 0), clinically meaningful collarette reduction to 10 collarettes or fewer (grade 0 or 1), mite eradication (0 mites/lash), erythema cure (grade 0), composite cure (grade 0 for collarettes as well as erythema), compliance with the drop regimen, drop comfort, and adverse events. RESULTS: At day 43, the study group achieved a statistically significant (P < 0.0001) higher proportion of patients with collarette cure (56.0% vs. 12.5%), clinically meaningful collarette reduction to 10 collarettes or fewer (89.1% vs. 33.0%), mite eradication (51.8% vs. 14.6%), erythema cure (31.1% vs. 9.0%), and composite cure (19.2% vs. 4.0%) than the control group. High compliance with the drop regimen (mean ± standard deviation, 98.7 ± 5.3%) in the study group was observed, and 90.7% of patients found the drops to be neutral to very comfortable. CONCLUSIONS: Twice-daily treatment with lotilaner ophthalmic solution 0.25% for 6 weeks generally was safe and well tolerated and met the primary end point and all secondary end points for the treatment of Demodex blepharitis compared with vehicle control.

ABSTRACT

Purpose: To obtain consensus on Demodex blepharitis (DB) treatment using a modified Delphi panel process. Methods: Literature search identified gaps in knowledge surrounding treatment of DB. 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.

ABSTRACT

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.

ABSTRACT

A clear corneal incision (CCI) is the most commonly used entrance site in modern phacoemulsification cataract surgery. Despite some initial concerns about increased endophthalmitis rates through a self-sealing CCI, recent literature suggests that the risk of infection with proper wound construction and all other necessary precautions is minimal. The technique of creating a clear corneal incision has, with recent developments in corneal imaging, undergone critical appraisal leading to a better understanding of incision architecture. Many surgeons operate through smaller incisions, and they have a wide choice of surgical instruments to create their corneal incisions. The aim of this review is to discuss the history and the current status of clear corneal incision creation, the design and materials of surgical blades, and the current trends in manufacturing and sustainability. Although disposable instruments have some advantages and are very popular, recycling, if possible, and avoiding unnecessary plastic waste are important considerations. In any case, the step of CCI is a small one for the surgeon, but a big one for the eye. That is why it has to be done with the utmost precision and in-depth knowledge is important.

ABSTRACT

ABSTRACT: Ligneous conjunctivitis is a rare cause of chronic conjunctivitis that may be triggered by ocular insults such as trauma or infections. We present an interesting case of ligneous conjunctivitis caused by a viral infection that responded well to conservative management. Topical cyclosporine and heparin are a good treatment regimen that caused resolution of lesions and prevented recurrences.

ABSTRACT

PURPOSE: The goal of this study was to compare topical dexamethasone 1.5% in a novel formulation (OCS-01) once daily and BID versus vehicle for the treatment of inflammation and pain after cataract surgery. METHODS: This was a Phase II, double-masked, vehicle-controlled, randomized multicenter study. Adult patients with planned unilateral uncomplicated cataract surgery were randomized to receive OCS-01 once daily (n = 51), OCS-01 BID (n = 51), or matching vehicle (n = 51) for 15 days postsurgery. Primary end points were absence of anterior chamber cells (ACC; cells = 0) at Day 15 and absence of pain (score of "0") at postoperative Day 4. The Pearson χ2 test with a two-sided alpha = 0.1 was used to compare treatments. Safety was assessed in terms of adverse events and changes in intraocular pressure. FINDINGS: Treatment arms were generally similar in their baseline characteristics, with mean age ranging from 66 to 68 years, the proportion of male patients ranging from 29% to 37%, and 82% to 92% of each arm being White. On Day 15, a greater reduction in the percentage of eyes with ACC grade 0 was observed in the OCS-01 once daily (51%) and BID (66.7%) arms than in the vehicle arm (19.6%) (P = 0.0009 and P < 0.0001, respectively, using a Pearson χ2 test). On Day 4, the percentage of eyes with no pain was 72.5% (OCS-01 once daily), 62.7% (OCS-01 BID), and 45.1% (vehicle); statistical significance was reached for OCS-01 once daily (P = 0.005) and OCS-01 BID (P = 0.074) compared with vehicle. OCS-01 was well tolerated. A higher proportion of treatment-emergent adverse events, including ocular adverse events, were reported for the placebo group than for either OCS-01 group. IMPLICATIONS: OCS-01 once daily and BID were more effective than vehicle and well tolerated in the treatment of inflammation and pain after cataract surgery. CLINICALTRIALS: gov identifier: NCT04130802.

ABSTRACT

PURPOSE OF REVIEW: Private equity has made significant inroads into the specialty of ophthalmology. The purpose of this review is to evaluate the effect of private equity on clinical operations in an ophthalmic practice. RECENT FINDINGS: Private equity had become an important source of capital and management expertise that has resulted in the consolidation of many ophthalmic practices as an alternative to working for a hospital system, insurance carrier, or independent private practice. SUMMARY: The recent growth of private equity presence in ophthalmology has resulted in significant changes in clinical operations. These changes in clinical operations include the increased importance of data management and data analytics, economies of scale, synergies, and introduction of patient-shared billing opportunities. Although physician input into clinical operations is decreased, provisional care decision-making can be maintained.

ABSTRACT

Purpose: To assess the frequency of patients reducing the use of artificial tears (ATs) among patients with dry eye disease (DED) following lifitegrast treatment. Patients and Methods: Two independent analyses were performed using the data from the 1-year, randomized, multicenter, Phase 3 SONATA trial and a noninterventional, real-world evidence (RWE) study conducted in patients with DED who were treated with lifitegrast in the United States and Canada. In SONATA, patients who had used ATs in the lifitegrast and placebo groups were included. The RWE study reviewed patients' electronic medical records, prescribing patterns, and practices of physicians throughout the survey. These data were then used to compare the proportion of patients using ATs in the 6-month pre-index period versus the 12-month post-index period. Results: Of 293 patients (lifitegrast, n=195; placebo, n=98) from SONATA, 107 (lifitegrast, n=64; placebo, n=43) used ATs during the on-therapy period while 186 (lifitegrast, n=131; placebo, n=55) did not. Of those not using ATs, the proportion of patients in the lifitegrast group at any time was higher (~67% [n=131]) versus placebo (~56% [n=55]); this was the case at all study time-points (Days 90, 180, 270, and 360). The RWE study included 600 patient charts (US, n=550; Canada, n=50); 75.5% (n=453) reported AT use. There was ~40% decrease in the proportion of patients using ATs as adjunct DED therapy to lifitegrast in the post-index period (n=273) versus those in the pre-index period (n=453). Conclusion: The findings show that the reliance on AT use can be gradually reduced with lifitegrast treatment, eventually leading to a reduction in disease burden.

ABSTRACT

PURPOSE: To compare patient preferences of postoperative cataract surgery topical medication use between a 1-drop and a 3-drop regimen. SETTING: Two private cataract surgery centers. DESIGN: Open-label randomized self-controlled prospective study. METHODS: This study included 30 patients (60 eyes) undergoing routine cataract surgery in both eyes. In this contralateral eye study, 1 eye of each patient was randomized to the 1-drop regimen of intracameral delivery of moxifloxacin and dexamethasone suspension and topical bromfenac for 30 days. The other eye, randomized to the 3-drop regimen, received topical moxifloxacin 0.5% 4 times a day for 7 days and bromfenac 0.07% daily for 30 days postoperatively, along with prednisolone acetate 1% 4 times a day for 30 days. Patients reported their preferred regimen 2 weeks after the second surgery with a validated questionnaire. Secondary outcomes included subjective ocular pain, inflammation score, and out-of-pocket cost. Intraocular pressure (IOP) and macular thickness were also measured. RESULTS: Of the 29 patients, 28 (96.6%) significantly more preferred the eye treated with a 1-drop regimen. Self-reported pain, activity interference, and out-of-pocket cost were significantly less in the 1-drop group. Inflammation and 1-day uncorrected distance visual acuity were also significantly better in the 1-drop group. Macular thickness and mean IOP were similar between groups. CONCLUSIONS: Intracameral delivery of steroid and antibiotics was preferred by most of the patients undergoing cataract surgery. These eyes had significantly less pain, inflammation, activity interference, and out-of-pocket cost and significantly better uncorrected distance visual acuity at 1 day postoperatively. IOP and macular thickness were similar between groups.

ABSTRACT

Postrefractive surgery ectasia is a serious, sight-threatening complication seen after the following procedures: laser in situ keratomileusis, photorefractive keratectomy, small-incision lenticule extraction, radial keratotomy, and/or arcuate keratotomy. Specific risk factors may include age, corneal thickness, degree of refractive error, corneal topographic changes including irregular astigmatism, percent tissue ablation, and residual stromal bed. Biomarkers may be a new option to help indicate who is at greatest risk for ectasia. Visual aids including spectacles or contacts lenses are often required to achieve optimal vision. Collagen crosslinking is the only treatment believed to stop progression of ectasia and prevent keratoplasty. Other surgical options may include topography-guided phototherapeutic keratectomy and intrastromal corneal ring segments. Ultimately, an "ounce of prevention is a pound of cure," so careful preoperative screening and ultimately offering the safest and most effective treatments for patients is arguably the most important job of the refractive surgeon.

ABSTRACT

PURPOSE: To compare pain and the need for the opioid fentanyl use associated with the administration of phenylephrine 1.0%-ketorolac 0.3% (P/K) with those of epinephrine administration during cataract surgery. SETTING: Ambulatory surgery center. DESIGN: Single-center, prospective, randomized, double-masked, self-controlled trial. METHODS: Patients undergoing bilateral, topical anesthetic cataract surgery were randomized to receive either intracameral P/K or epinephrine in their balanced salt solution for the first eye and the other for the second eye, 2 weeks later. Fentanyl was used to manage intraoperative pain. The primary end point was the need for fentanyl administration intraoperatively. Secondary outcomes included pain measurements; surgery duration; effective phacoemulsification time; pupil size; and complications. RESULTS: 112 eyes of 56 patients were enrolled. Significantly fewer eyes in the P/K group (7 [12.5%]) than in the epinephrine group (19 [33.9%]; P = .013) required intraoperative fentanyl administration. Mean pain scores were lower in the P/K group than those in the control group at all timepoints. For patients with no pain to mild pain (pain scores ≤ 3), 85.7% (n = 48) of the P/K group and 58.9% (n = 33) of the epinephrine group met this benchmark ( P = .003) intraoperatively. The combined outcome, the number of patients not receiving intravenous fentanyl and experiencing no pain to mild pain, was significantly higher in the study (82.1%, n = 46) than in the control group (58.9%, n = 33; P = .013). CONCLUSIONS: P/K administration significantly reduced pain and the need for fentanyl use. Using P/K is a practical way for cataract surgeons to provide better patient care and reduce the need for intraoperative opioids.

ABSTRACT

Meibomian glands are modified oil-producing glands that produce meibum and can become dysfunctional and negatively affect the lipid layer in the tear film, resulting in ocular surface diseases such as evaporative dry eye. Abnormal keratin production and aggregation at the meibomian gland orifice has been implicated in the pathogenesis of meibomian gland dysfunction (MGD). Current treatments largely ignore the role of keratin proteins. This review paper synthesizes various publications on hyperkeratinization and its role in MGD pathogenesis and proposes a novel treatment strategy for MGD that involves the use of keratolytic agents commonly used in dermatological treatments.

ABSTRACT

IMPORTANCE: An investigation of the treatment effect of lifitegrast ophthalmic solution, 5.0%, in different subgroups by severity of dry eye disease (DED) seems warranted. OBJECTIVE: To explore the heterogeneity across different subgroups of DED and identify which participants were most likely to achieve clinically meaningful benefit with lifitegrast treatment. DESIGN, SETTING, AND PARTICIPANTS: This post hoc responder analysis was performed using the data from the phase 3 OPUS-2 and OPUS-3 studies, which were 12-week, prospective, double-masked, multicenter, placebo-controlled, randomized, parallel-arm clinical trials that previously demonstrated the efficacy of lifitegrast in DED. Pooled data were stratified into 4 subgroups based on severity of inferior corneal staining score (ICSS; ≤1.5 vs >1.5) and eye dryness score (EDS; <60 or ≥60) at baseline. Data were collected from December 7, 2012, to October 5, 2015, and post hoc analysis was performed from April 14, 2020, to July 30, 2021. INTERVENTIONS: Lifitegrast or placebo twice daily for 84 days. MAIN OUTCOMES AND MEASURES: Proportion of participants with (1) a clinically meaningful improvement in signs (ICSS or total corneal staining score [TCSS]) and symptoms (EDS or global visual analog scale [VAS]) and (2) a composite response for a given sign and symptom end point pair at day 84 were measured. Clinically meaningful improvement was defined as at least 30% improvement in symptoms (EDS or global VAS) and either at least a 1-point improvement in ICSS or at least a 3-point improvement in TCSS. For the composite responder analysis, the end point pairs were defined as at least a 30% reduction in EDS and at least a 1-point improvement in ICSS; at least a 30% reduction in EDS and at least a 3-point improvement in TCSS; at least a 30% improvement in global VAS and at least a 1-point improvement in ICSS; and at least a 30% improvement in global VAS and at least a 3-point improvement in TCSS. RESULTS: In total, 1429 participants (716 in the placebo group and 713 in the lifitegrast group) were analyzed (1087 women [76.1%]; mean [SD] age, 58.7 [14.3] years). For the overall pooled population, responder and composite responder rates favored lifitegrast vs placebo (odds ratio range, 1.29 [95% CI, 1.05-1.59] to 2.10 [95% CI, 1.68-2.61]; P ≤ .02). In the composite analysis, the subgroup with ICSS of greater than 1.5 and EDS of at least 60 at baseline (ie, moderate to severe DED) demonstrated a 1.70- to 2.11-fold higher odds of achieving clinically meaningful improvement with lifitegrast across all sign and symptom end point pairs (P ≤ .001). CONCLUSIONS AND RELEVANCE: These post hoc findings suggest that lifitegrast ophthalmic solution, 5.0%, treatment may be associated with a response in participants with moderate to severe signs and symptoms of DED.

ABSTRACT

Presbyopia is a common age-related vision disorder characterized by a progressive inability to focus on near objects. 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.
