Recombinant human nerve growth factor (cenegermin) for moderate-to-severe dry eye: phase II, randomized, vehicle-controlled, dose-ranging trial.

BACKGROUND: Dry eye disease (DED) includes neurosensory abnormalities as part of its multifactorial etiology. Nerve growth factor is important for maintaining corneal nerve integrity and wound healing. Cenegermin (recombinant human nerve growth factor) is a topical biologic that promotes corneal healing in patients with neurotrophic keratitis. The purpose of this study was to evaluate efficacy and safety of cenegermin in moderate-to-severe DED and identify an optimal dosing strategy. METHODS: This was a phase II, multicenter, randomized, double-masked, vehicle-controlled, dose-ranging clinical trial in patients with moderate-to-severe DED, including Sjögren's DED (NCT03982368). Patients received 1 drop of cenegermin 3 times daily (t.i.d.; 20 mcg/mL), cenegermin 2 times daily (b.i.d.; 20 mcg/mL) and vehicle once daily, or vehicle t.i.d. for 4 weeks. Follow-up continued for 12 additional weeks. The primary endpoint was change in Schirmer I score from baseline to week 4. Other key endpoints included rate of responders (Schirmer I test > 10 mm/5 min) after treatment and change in Symptoms Assessment iN Dry Eye (SANDE) scores from baseline to end of follow-up. A 1-sided test (α = 0.025) was used to evaluate statistical significance. RESULTS: At week 4, mean changes in Schirmer I scores were not statistically significantly different in either cenegermin group versus vehicle (cenegermin vs vehicle [treatment difference; 95% CI]: t.i.d., 2.60 mm and b.i.d., 3.99 mm vs 1.68 mm [t.i.d.: 0.93; -1.47 to 3.32, P = 0.078; b.i.d.: 2.31; -0.08 to 4.70, P = 0.066]). More patients responded to treatment with cenegermin t.i.d. and b.i.d. versus vehicle (t.i.d.: 25.9% [21/81, P = 0.028]; b.i.d.: 29.3% [24/82, P = 0.007] vs 11.9% [10/84]), with statistical significance (set at P < 0.025) observed in the b.i.d. group. Only cenegermin t.i.d. yielded statistically significant (P < 0.025) reductions in SANDE scores versus vehicle, which were sustained up to the end of follow-up (P value range, 0.002-0.008). Eye pain, primarily mild and transient, was the most frequently observed treatment-emergent adverse event with cenegermin. Similar results were observed in patients with Sjögren's DED. CONCLUSIONS: Cenegermin was well tolerated and although this study did not meet its primary endpoint, significant improvement in patient-reported symptoms of dry eye was observed through follow-up. Larger studies evaluating cenegermin in patients with DED are warranted. TRIAL REGISTRATION: NCT03982368; registered May 23, 2019.

Results from a Prospective, Open-Label, Phase 4 Pilot Study of Repository Corticotropin Injection for Moderate and Severe Dry Eye Disease.

INTRODUCTION: There is a substantial unmet need for effective therapies to treat patients with refractory dry eye disease (DED). The goal of this open-label pilot study was to investigate the efficacy and safety of repository corticotropin injection (RCI; Acthar® Gel; Mallinckrodt Pharmaceuticals) in subjects with DED, most of whom did not experience adequate response to standard-of-care therapies. METHODS: Adults with moderate or severe-acute DED received 80 U of subcutaneous RCI twice weekly for 12 weeks. Primary efficacy outcomes were improvements in corneal fluorescein staining of superficial punctate keratitis (SPK) lesions and Symptom Assessment in Dry Eye (SANDE) scores. Secondary outcomes included changes in Schirmer's test scores, conjunctival lissamine green staining, erythema, intraocular pressure (IOP), and best corrected visual acuity (BCVA). Adverse events (AEs) were assessed continuously throughout the study. RESULTS: Fifteen subjects received at least 1 dose of RCI, and 12 subjects completed the study. Compared to baseline (day 1), significantly fewer fluorescein-stained SPK lesions were detected at day 14 (p = 0.0250) and day 84 (p = 0.0240) after RCI treatment. Mean SANDE scores progressively declined from 62.0 at baseline to 46.9 at day 84. Erythema (p = 0.0046), conjunctival lissamine green staining of SPK lesions (p = 0.0317), and IOP (p = 0.0052) were all significantly improved after 12 weeks of RCI therapy. Schirmer's test scores and BCVA showed no significant changes throughout the study. No ocular AEs or deaths occurred, and no new safety signals were identified for RCI. CONCLUSIONS: These results suggest that RCI may be a safe and effective treatment for moderate and severe DED. TRIAL REGISTRATION: ClinicalTrials.gov identifier: NCT03287635.

The Effect of OTX-101 on Tear Production in Patients with Severe Tear-deficient Dry Eye Disease: A Pooled Analysis of Phase 2b/3 and Phase 3 Studies.

PURPOSE: Impaired tear production - a common sign of keratoconjunctivitis sicca (KCS) - is associated with qualitative or quantitative tear deficiency. OTX-101 0.09% is a novel, nanomicellar formulation of cyclosporine A approved in the US for increasing tear production in patients with KCS. We present a pooled analysis of the phase 2b/3 and phase 3 studies evaluating the effect of OTX-101 on tear production in a subgroup of patients with keratoconjunctivitis sicca with severely impaired tear production (Schirmer's score <5 mm in either eye at baseline). METHODS: In these randomized, double-masked studies, patients instilled 1 drop OTX-101 or vehicle per eye twice daily for 84 days. Pooled efficacy endpoints included percent (%) of patients with ≥10 mm change from baseline and mean change from baseline in Schirmer's score at day 84. Pooled safety endpoints included adverse event monitoring. RESULTS: Subgroup analyses included 133 and 113 patients receiving OTX-101 and vehicle, respectively. Mean baseline (BL) Schirmer's score ± standard deviation was 2.7 ± 1.2 for OTX-101 and 2.5 ± 1.1 mm for vehicle (P = .3203). On day 84, number (%) of patients with ≥10 mm Schirmer's score change from baseline was 30 (22.6%) and 12 (10.6%, P = .0168); mean change from baseline ± standard deviation was 5.5 ± 8.0 and 3.6 (6.0, P = .0405) mm for OTX-101 and vehicle, respectively. Adverse events were mostly mild and did not require treatment. CONCLUSION: OTX-101 administered twice daily for 84 days significantly improved tear production vs vehicle in patients with severely impaired tear production, as evidenced by significantly larger proportion of patients with ≥10 mm increases from baseline and higher mean change from baseline in Schirmer's scores.

Selective Pharmacologic Therapies for Dry Eye Disease Treatment: Efficacy, Tolerability, and Safety Data Review from Preclinical Studies and Pivotal Trials.

Keratoconjunctivitis sicca, also known as dry eye disease (DED), is a prevalent, multifactorial disease associated with compromised ocular lubrication, ocular surface inflammation and damage, and ocular symptoms. Several anti-inflammatory, topical ophthalmic therapies are available to treat clinical signs and symptoms of DED in the USA and Europe. Cyclosporine A (CsA)-based formulations include an ophthalmic emulsion of 0.05% CsA (CsA 0.05%), a cationic emulsion (CE) of CsA 0.1% (CsA CE), and an aqueous nanomicellar formulation of 0.09% CsA (OTX-101). Lifitegrast is a 5% ophthalmic solution of a lymphocyte function-associated antigen 1 antagonist that is believed to target T cell activation and recruitment to inhibit ocular inflammation. Here we provide a comprehensive review summarising preclinical studies and pivotal trial data for these treatments to provide a complete understanding of their efficacy and safety profile. Overall, data in the evaluated studies show a favourable risk-benefit profile for the use of targeted topical anti-inflammatory pharmacologic treatments in patients with DED. Pivotal trials for CsA 0.05%, CsA CE, OTX-101, and lifitegrast clearly demonstrate treatment efficacy compared to vehicle across treatments with no serious ocular treatment-emergent adverse events (TEAEs). Patients using ophthalmic treatments reported ocular TEAEs more frequently than those treated with vehicle; however, relatively few TEAEs led to treatment discontinuation. The specific signs and symptoms of DED that improve with treatment vary with the treatment prescribed. Long-term and direct comparative studies between treatments are needed to further understand treatment differences in efficacy and safety profiles.

Intense pulsed light improves signs and symptoms of dry eye disease due to meibomian gland dysfunction: A randomized controlled study.

PURPOSE: To compare the safety and efficacy of intense pulsed light (IPL) followed by meibomian gland expression (MGX), against monotherapy of MGX. METHODS: Patients with moderate to severe meibomian gland dysfunction (MGD) were 1:1 randomized to 4 sessions of intense pulse light + MGX at 2-week intervals, or 4 sessions of Sham + MGX at 2-week intervals. Both patients and examiners were blinded to the allocation. Outcome measures, evaluated at the baseline (BL) and at a follow-up (FU) conducted 4 weeks after the last IPL session, included fluorescein tear breakup time (TBUT) as the primary outcome measure, OSDI (Ocular Surface Disease Index) questionnaire, Eye Dryness Score (EDS, a visual analog scale (VAS)-based questionnaire), Meibomian gland score (MGS, a score of meibum expressibility and quality in 15 glands on the lower eyelid), daily use of artificial tears, and daily use of warm compresses. In addition, during each treatment session, the number of expressible glands was counted in both eyelids, the predominant quality of meibum was estimated in both eyelids, and the level of pain/discomfort due to MGX and IPL was recorded. RESULTS: TBUT increased from 3.8±0.2 (µ±standard error of mean (SEM)) to 4.5±0.3 seconds in the control arm, and from 4.0±0.2 to 6.0±0.3 in the study arm. The difference between arms was statistically significant (P < .01). Other signs/symptoms which improved in both arms but were greater in the study arm included MGS (P < .001), EDS (P < .01), the number of expressible glands in the lower eyelids (P < .0001) and upper eyelid (P < .0001), the predominant meibum quality in the lower eyelid (P < .0001) and upper eyelid (P < .0001), and the level of pain due to MGX (P < .0001). Outcome measures which improved in both arms with no significant differences between the two were OSDI (P = .9984), and the daily use of artificial tears (P = .8216). Meibography, daily use of warm compresses, and severity of skin rosacea did not show statistically significant changes in either arm. No serious adverse events were observed. There was a slight tendency for more adverse events in the control group (P = 0.06). CONCLUSIONS: The results of this study suggest that, in patients with moderate to severe symptoms, combination therapy of intense pulse light (IPL) and meibomian gland expression (MGX) could be a safe and useful approach for improving signs of dry eye disease (DED) due to meibomian gland dysfunction (MGD). Future studies are needed to elucidate if and how such improvements can be generalized to different severity levels of MGD.

Topical Ocular Anti-TNFα Agent Licaminlimab in the Treatment of Acute Anterior Uveitis: A Randomized Phase II Pilot Study.

Purpose: Licaminlimab is a new anti-TNFα antibody fragment for topical ocular application. This phase II study assessed the tolerability, treatment effect, and pharmacokinetics of licaminlimab in acute anterior uveitis (AAU). Methods: In this multicenter, randomized, parallel-group, double-masked study, 43 adult patients with non-infectious AAU and Standardization of Uveitis Nomenclature (SUN) anterior chamber (AC) cell score of 2+ or 3+ were randomized (3:1 ratio) to licaminlimab (60 mg/mL, 8 drops/day for 15 days, 4 drops/day for 7 days, then matching vehicle for 7 days) or dexamethasone eye drops (8 drops/day for 15 days, tapering to 1 drop/day over 14 days). The primary efficacy end point was clinical response (≥2-step decrease in AC cell grade at day 15). A treatment effect was considered as established if the lower limit of the 95% posterior interval of the responder rate was >30%. Serum levels of licaminlimab were determined. Results: The day 15 response rate for licaminlimab was 56%; the lower bound of the 95% credible interval was 40% (i.e. >30%), demonstrating a treatment effect according to prespecified criteria. By day 4, 36% of licaminlimab-treated patients were responders; 76% had an AC cell grade of 0 on ≥1 post-treatment visit. The day 15 dexamethasone response rate was 90% (no inferential between-arm comparison was planned). Both treatments were well-tolerated. Intraocular pressure increased from baseline with dexamethasone but not licaminlimab. Licaminlimab was undetectable in serum in most patients. Conclusions: Licaminlimab is the first biologic demonstrated to have a treatment effect on an intraocular condition with topical ocular application. The trial met its primary objective and the observed responder rate for licaminlimab was 56.0%. Ocular administration of licaminlimab was well-tolerated in adult subjects with AAU for up to 35 days.

Effect of OTX-101 in Patients with Dry Eye Disease at Day 14 of Treatment: Ocular Surface Endpoint Results from the Phase 2b/3 Clinical Trial.

Dry eye disease (DED) is a multifactorial disorder characterized by loss of tear film homeostasis, which initiates a cycle of ocular surface inflammation and damage. As ocular discomfort symptoms associated with DED can decrease quality of life, affected patients prefer treatments that rapidly improve the underlying disease process. OTX-101 0.09% (CEQUA®) is indicated to increase tear production in patients with DED. The current analysis assessed early efficacy of OTX-101 0.09% in adult patients with bilateral DED by evaluating ocular surface endpoints after 14 days of treatment in the phase 2b/3 trial. In this randomized, double-masked, vehicle-controlled, dose-ranging study, patients received one drop of OTX-101 0.05%, OTX-101 0.09%, or vehicle per eye twice daily for 84 days. Corneal staining, conjunctival staining, tear breakup time (TBUT), and modified Symptom Assessment iN Dry Eye (SANDE) total global symptom score were assessed at baseline and Days 14, 28, 42, 56, and 84/early discontinuation. Overall, 455 patients were randomized (OTX-101 0.05%, n=151; OTX-101 0.09%, n=152; vehicle, n=152); only baseline and Day 14 results for the approved OTX-101 0.09% formulation and vehicle are presented. Least squares (LS) mean (standard error [SE]) change from baseline in conjunctival staining score was -1.3 (0.1) for OTX-101 and -1.0 (0.1) for vehicle. LS mean (SE) change from baseline in corneal staining score was -1.1 (0.17) for OTX-101 and -0.7 (0.17) for vehicle. LS mean (SE) change from baseline in TBUT was 0.52 (0.15) for OTX-101 and 0.36 (0.15) for vehicle. LS mean (SE) change from baseline in modified SANDE total global symptom score was -4.93 (1.54) for OTX-101 and -9.1 (1.54) for vehicle. OTX-101 0.09% demonstrated a numerically greater treatment effect compared with vehicle in conjunctival staining, corneal staining, and TBUT after 14 days.

Management of repository corticotropin injection therapy for non-infectious uveitis: a Delphi study.

PURPOSE: Diagnosis and management of non-infectious uveitis (NIU), a major cause of blindness worldwide, are challenging. Corticosteroids, the cornerstone of therapy, are not appropriate for long-term use, and while non-biologic and biologic immunomodulators may be used for some patients, data on their efficacy and safety in this population are limited. Repository corticotropin injection (RCI), believed to affect uveitis by multiple mechanisms, has received regulatory approval for treatment of ophthalmic diseases including posterior uveitis, but is not widely used or discussed in guidelines for the management of uveitis and ocular inflammatory diseases. METHODS: The index study employed a modified Delphi process with a panel of 14 US-based ophthalmologists. Consensus recommendations were developed through a series of three questionnaires. Panellists rated statements on a Likert scale from -5 (strongly disagree) to +5 (strongly agree). RESULTS: The Delphi panel provided consensus recommendations on examinations and testing needed for diagnosis, treatment goals, and the use of corticosteroids, as well as the use of non-biologic and biologic immunomodulators. The panel reached consensus that RCI may be considered for posterior and pan-uveitis, and dosing should be individualized for each patient. Dose reduction/discontinuation should be considered for excessive RCI-related toxicity, hyperglycaemia and/or diabetic complications, excessive costs, or remission ≥ 2 years. Patients should be weaned from RCI if uveitis is stable and well controlled. Adverse events during RCI therapy can be managed by appropriate interventions, with dose reduction/discontinuation considered if events are severe or recurrent. CONCLUSIONS: Expert consensus suggests RCI may be an appropriate treatment option for some patients with uveitis when other therapies are ineffective or intolerable.

Comparison of Once-Daily Bromfenac 0.07% Versus Once-Daily Nepafenac 0.3% in Patients Undergoing Phacoemulsification.

AIM: Randomized pilot study comparing clinical outcomes with bromfenac ophthalmic solution 0.07% versus nepafenac 0.3% ophthalmic suspension administered as identical dosing regimens in patients undergoing uncomplicated phacoemulsification with intraocular lens implantation. METHODS: Forty-nine subjects were treated with bromfenac (n = 25) or nepafenac (n = 24) once daily starting 3 days before cataract surgery, continued on the day of surgery, and for 21 days following surgery, in addition to standard of care. Subjects were followed at 1 day and 7, 21, and 42 days postoperatively. Assessments included best-corrected visual acuity [Early Treatment Diabetic Retinopathy Study (ETDRS)], summed ocular inflammation score (SOIS; anterior chamber cells plus flare grading), macular volume and thickness (spectral domain optical coherence tomography), intraocular pressure, and adverse events. RESULTS: Treatment groups were similar at baseline. Outcomes for mean letters read (p = 0.20), mean change in macular volume (p = 0.98), and retinal thickness (p = 0.93) were not statistically different between the groups at day 42. Mean SOIS dropped markedly and similarly from post-surgical day 1 to day 7 in both treatment groups and was statistically equivalent to baseline in both groups by day 21. At day 42, 87% of subjects in the bromfenac group and 82% of subjects in the nepafenac group demonstrated stable or improved visual acuity. The proportions of eyes with mean retinal thickness of 10 µm or less at days 7, 21, and 42 were similar for the bromfenac (95.8%, 78.3%, 73.9%, respectively) and nepafenac (91.7%, 87.5%, 66.7%) groups (all p = NS, bromfenac vs. nepafenac). CONCLUSION: Both bromfenac 0.07% and nepafenac 0.3% produced positive and similar clinical outcomes with regard to ETDRS visual acuity post-cataract surgery when dosed using identical regimens. Increases in mean retinal thickness and mean macular volume were small and similar between treatments. TRIAL REGISTRATION NUMBER: NCT01847638. FUNDING: Bausch & Lomb Incorporated.

Evaluation of the Safety and Efficacy of Intense Pulsed Light Treatment with Meibomian Gland Expression of the Upper Eyelids for Dry Eye Disease.

Objective: To investigate the safety of and change from baseline of tear breakup time and visual analog pain scales in dry eye disease subjects with upper lid Meibomian gland dysfunction after intense pulsed light (IPL) treatment assessing global ocular pain severity, ocular pain frequency, and ocular pain in the previous 24 h. This is a prospective single-site study. Methods: All patients received active treatment consisting of four treatments spaced no fewer than 2 weeks apart and no longer than 4 weeks apart. The IPL therapy was performed with a Lumenis M22 (Lumenis Ltd., Yokneam, Israel) xenon-based micropulsed IPL utilizing a 590 nm filter with a 6 mm clear SapphireCool cylindrical lightguide for the upper lids with a fluence of 10 J/cm2 across the upper eyelids, including the tragus for two passes. Patients then received expression of their meibomian glands using two cotton-tipped applicators. Tear breakup data were collected as well as global ocular pain, ocular pain episodes in the past 24 h and frequency of ocular pain episodes. Results: All of the assessments for the treated eyes improved over the course of treatment. Statistically significant physician increases in measured tear breakup times were measured for each eye independently. Statistically significant decreases in global eye dryness scale, eye dryness in the preceding 24 h, and frequency of ocular pain episodes between treatments were observed. There were no serious or nonserious adverse events in the trial. Conclusions: This pilot study suggests that a new specialized 6 mm cylindrical handpiece for the M22 Lumenis IPL machine is safe and effective in increasing physician-measured tear breakup time as well as several scales of the symptoms of ocular dryness, including global symptoms, frequency of symptoms, and ocular dryness occurring within the previous 24 h before the study visit.

Difluprednate 0.05% versus Prednisolone Acetate 1% for Endogenous Anterior Uveitis: Pooled Efficacy Analysis of Two Phase 3 Studies.

Purpose: To analyse pooled data from 2 similar phase 3 noninferiority studies comparing difluprednate 0.05% versus prednisolone acetate 1% in patients with endogenous anterior uveitis. Methods: Patients received difluprednate alternating with vehicle or prednisolone acetate for 14 days (8 drops/day in both groups), followed by tapering from day 14 to 28. All patients were observed until day 42. Results: More patients on difluprednate than on prednisolone acetate were cleared of anterior chamber cells on day twenty one (71.3% vs 54.7%; p = 0.02); results were similar at the other time points. Treatment withdrawals were higher with prednisolone acetate than difluprednate (19.8% vs 7.4%; log-rank p = 0.02). Study discontinuation due to lack of efficacy was also higher with prednisolone acetate than difluprednate (14.0% vs 0%; p = 0.0002 [pre-specified exploratory analysis]). Conclusions: More difluprednate-treated eyes were quiet following 21 days of treatment, and difluprednate-treated patients were much less likely to be withdrawn from the study because of treatment failure.

A Phase II/III, randomized, double-masked, vehicle-controlled, dose-ranging study of the safety and efficacy of OTX-101 in the treatment of dry eye disease.

PURPOSE: The aim of this study was to evaluate the safety and efficacy of OTX-101, a clear nanomicellar aqueous solution of cyclosporine, in the treatment of dry eye disease (DED). PATIENTS AND METHODS: This was a 12-week multicenter, randomized, prospective, double-masked, vehicle-controlled, dose-ranging clinical trial. Subjects were adults aged ≥18 years, with a total conjunctival staining score of ≥3 and ≤9, and global DED symptom score ≥40 (0-100 visual analogue scale). Following a 14-day vehicle run-in, subjects were randomized in a 1:1:1 ratio to twice daily treatment with OTX-101 0.09%, OTX-101 0.05%, or vehicle for 84 days. Co-primary efficacy end points were changes, from baseline to Day 84, in the total lissamine green conjunctival staining score in the designated study eye and in the global symptom score (both eyes). Secondary end points included total corneal fluorescein staining score, tear breakup time, and Schirmer's test score. RESULTS: In total, 455 subjects were randomized. Subjects treated with active drug experienced greater improvement in conjunctival staining than vehicle-treated patients (P<0.01 for both concentrations). All groups demonstrated improvements in global symptom score, but there were no differences among groups. Nominally significant differences were found between the active drug arms and vehicle for corneal staining scores and Schirmer's test scores. Most treatment-emergent adverse events were mild in severity; no serious ocular adverse events were reported. CONCLUSIONS: Both concentrations of OTX-101 met the co-primary sign end point (conjunctival staining) but not the co-primary symptom end point. OTX-101 0.09% demonstrated a notable impact on multiple signs of DED relative to vehicle and was well-tolerated.

Ocular comfort assessment of lifitegrast ophthalmic solution 5.0% in OPUS-3, a Phase III randomized controlled trial.

PURPOSE: To evaluate ocular comfort of lifitegrast ophthalmic solution 5.0% among patients with dry eye disease (DED) in the OPUS-3 trial. METHODS: OPUS-3 was a multicenter, randomized, double-masked, placebo-controlled study. Adults with DED and recent artificial tear use were randomized 1:1 (lifitegrast:placebo) to ophthalmic drops twice daily for 84 days. On days 0 (baseline), 14, 42, and 84, drop comfort score (scale, 0-10; 0 = very comfortable, 10 = very uncomfortable) was measured at 0, 1, 2, and 3 minutes postinstillation. If the score was >3 at 3 minutes, assessment was repeated at 5, 10, and 15 minutes until score ≤3. Ocular treatment-emergent adverse events (TEAEs) were assessed. RESULTS: Overall, 711 participants were randomized (n=357 received lifitegrast; n=354 received placebo). Drop comfort scores for lifitegrast-treated participants improved within 3 minutes of instillation (mean scores on day 84 for both study and fellow eyes: instillation: lifitegrast, 3.4, placebo, 1.0; 3 minutes: lifitegrast, 1.5, placebo, 0.7). The majority (64%-66%) of participants had scores <3 within 3 minutes postinstillation on days 14, 42, and 84. In participants with scores >3 at 3 minutes, the mean score in the lifitegrast group was similar to or better than that in the placebo group at 5, 10, or 15 minutes postinstillation. Lifitegrast appeared to be well tolerated, with ocular TEAEs rarely leading to discontinuation. CONCLUSION: In OPUS-3, lifitegrast appeared to be well tolerated and drop comfort scores approached placebo levels by 3 minutes postinstillation.

Continuous Wave Fractional CO2 Laser for the Treatment of Upper Eyelid Dermatochalasis and Periorbital Rejuvenation.

Fractional continuous wave CO2 laser resurfacing is used to improve photodamage, wrinkles, and acne scarring by surface ablation and by using heat to activate natural collagen production and dermal remodeling. In this study, the author examined the efficacy and safety of nonincisional continuous wave fractional CO2 laser blepharoplasty in the upper lid. Standard lid measurements including marginal reflex distance, palpebral fissure, and upper lid crease were performed preoperatively and at 6 months by the surgeon. All patients underwent full facial MIXTO continuous wave CO2 laser treatment (MIXTO Slim Evolution 2; MIXTOLasering USA, San Ramon, CA), including resurfacing on the upper eyelid from lashes to brow. We evaluated results at 6 months after laser treatment and found that on average, after MIXTO continuous wave laser treatment, marginal reflex distance of the upper lid increased from baseline from 0.7 to 2.2 mm, palpebral fissures increased from 5.6 to 7.4 mm, the upper lid crease was unchanged at 5.7 mm as was the upper lid excursion at 14.7 mm compared with those before treatment. Patients reported postoperative erythema, edema, crusting, and oozing that resolved within 14 days. These data demonstrate the safety and efficacy of noninvasive continuous wave fractional CO2 laser in the treatment of mild and moderate upper eyelid dermatochalasis.

Analysis of Cytokine Levels in Tears and Clinical Correlations After Intense Pulsed Light Treating Meibomian Gland Dysfunction.

PURPOSE: To investigate the change from baseline of inflammatory markers in tears of dry eye disease (DED) subjects owing to meibomian gland dysfunction (MGD) after intense pulsed light (IPL) treatment and meibomian gland expression (MGE) compared to sham treatment, and the correlations with ocular surface parameters. DESIGN: Randomized, double-masked, controlled study. METHODS: Those randomized into the active treatment arm received 3 consecutive treatments (14∼16 J/cm2) approximately 4 weeks apart in the periocular region. Control eyes received 3 treatments in the same intervals of 0 J/cm2. Tear samples in all eyes were collected and analyzed at baseline, week 12, and/or week 4 for interleukin (IL)-17A, IL-6, and prostaglandin E2 (PGE2). The correlations between cytokines and ocular surface parameters were analyzed before and after IPL treatment. RESULTS: All of the inflammatory markers declined in value compared to baselines. IL-17A and IL-6 showed statistically significant decreases compared to sham treatment at each measured time point. PGE2 showed statistically significant decreases compared to sham at week 12. Results showed that the expressions of IL-17A and IL-6 correlated well with ocular surface parameters of the lower eyelid before IPL. The changed values of IL-6 and PGE2 in tears correlated with the changed values of partial ocular surface parameters after IPL treatment in study eyes, respectively. CONCLUSIONS: The study results suggest that IPL can significantly reduce inflammatory markers in tears of patients suffering with DED owing to MGD after IPL treatment. These findings indicate that IL-17A and IL-6 play roles in the pathogenesis of DED owing to MGD, and the reduction of the inflammatory factors is consistent with the improvement of partial clinical symptoms and signs.

Clinical and patient-reported outcomes of bilateral implantation of a +2.5 diopter multifocal intraocular lens.

PURPOSE: To assess the effectiveness and safety of a multifocal intraocular lens (IOL) with +2.5 diopter (D) additional power compared with a monofocal IOL. SETTING: Fifteen sites in the United States. DESIGN: Prospective randomized patient- and observer-masked clinical trial. METHODS: Randomized patients received multifocal or monofocal IOLs bilaterally. Visual acuity (33 cm, 40 cm, 53 cm, 60 cm, 4 m) was measured; safety was assessed through adverse event rates. Patient-reported visual outcomes were evaluated using the Visual Tasks questionnaire. The frequency and severity of visual disturbances were evaluated using the Assessment of Photic Phenomena and Lens EffectS questionnaire. RESULTS: The multifocal IOL (n = 155) provided better corrected distance visual acuity at 53 cm than the monofocal IOL (n = 165) (0.322 versus 0.512 logMAR; between-group difference, -0.190 logMAR; P < .0001) and 40 cm but not at 4 m. Ocular adverse event rates were less than 3.84% in both groups. Serious adverse event rates were comparable between the 2 IOL types. Patients with multifocal IOLs reported less difficulty with near tasks (with and without correction) and intermediate tasks (without correction). Difficulty with extended-intermediate and distance tasks was similar between groups. The most frequently reported self-rated severe phenomena were halos, starbursts, and glare. Most patients (monofocal ≥72%; multifocal ≥73%) reported never experiencing blurred, distorted, or double vision. CONCLUSIONS: The +2.5 D multifocal IOL provided better vision at 40 cm and 53 cm and similar vision at 4 m compared with the monofocal IOL. Safety profiles and visual phenomena were comparable between groups.

Effect of Oral Re-esterified Omega-3 Nutritional Supplementation on Dry Eyes.

PURPOSE: To assess the effect of oral re-esterified omega-3 fatty acids on tear osmolarity, matrix metalloproteinase-9 (MMP-9), tear break-up time (TBUT), Ocular Surface Disease Index (OSDI), fluorescein corneal staining, Schirmer score, meibomian gland dysfunction (MGD) stage and omega-3 index in subjects with dry eyes and confirmed MGD. METHODS: This was a multicenter, prospective, interventional, placebo-controlled, double-masked study. Subjects were randomized to receive 4 softgels containing a total of 1680 mg of eicosapentaenoic acid/560 mg of docosahexaenoic acid or a control of 3136 mg of linoleic acid, daily for 12 weeks. Subjects were measured at baseline, week 6, and week 12 for tear osmolarity, TBUT, OSDI, fluorescein corneal staining, and Schirmer test with anesthesia. MMP-9 testing and omega-3 index were done at baseline and at 12 weeks. RESULTS: One hundred five subjects completed the study. They were randomized to omega-3 (n = 54) and control group (n = 51). Statistically significant reduction in tear osmolarity was observed in the omega-3 group versus control group at week 6 (-16.8 ± 2.6 vs. -9.0 ± 2.7 mOsm/L, P = 0.042) and week 12 (-19.4 ± 2.7 vs. -8.3 ± 2.8 mOsm/L, P = 0.004). At 12 weeks, a statistically significant increase in omega-3 index levels (P < 0.001) and TBUT (3.5 ± 0.5 s vs. 1.2 ± 0.5 s, P = 0.002) was also observed. Omega-3 group experienced a significant reduction in MMP-9 positivity versus control group (67.9% vs. 35.0%, P = 0.024) and OSDI scores decreased significantly in omega-3 (-17.0 ± 2.6) versus control group (-5.0 ± 2.7, P = 0.002). CONCLUSIONS: Oral consumption of re-esterified omega-3 fatty acids is associated with statistically significant improvement in tear osmolarity, omega-3 index levels, TBUT, MMP-9, and OSDI symptom scores.

Difluprednate 0.05% versus prednisolone acetate 1% for endogenous anterior uveitis: a phase III, multicenter, randomized study.

PURPOSE: Endogenous anterior uveitis (AU), when untreated, may lead to vision loss. This study compared the safety and efficacy of difluprednate versus prednisolone acetate for the treatment of this condition. METHODS: This phase III, double-masked, noninferiority study randomized patients with mild to moderate endogenous AU to receive difluprednate 0.05% (n = 56) four times daily, alternating with vehicle four times daily, or prednisolone acetate 1% (n = 54) eight times daily. The 14-day treatment period was followed by a 14-day dose-tapering period and a 14-day observation period. The primary efficacy end point was change in anterior chamber cell grade (range, 0 for ≤1 cell to 4 for >50 cells) from baseline to day 14. RESULTS: At day 14, the mean change in anterior chamber cell grade with difluprednate was noninferior to that with prednisolone acetate (-2.2 vs. -2.0, P = 0.16). The proportions of difluprednate-treated patients versus prednisolone acetate-treated patients demonstrating complete clearing of anterior chamber cells at day 3 were 13.0% vs. 2.1% (P = 0.046) and at day 21 were 73.9% vs. 63.8% (P = 0.013). A significant between-group difference in the mean IOP increase was seen at day 3 (2.5 mm Hg for difluprednate-treated patients and 0.1 mm Hg for prednisolone acetate-treated patients, P = 0.0013) but not at other time points. The mean IOP values in both groups remained less than 21 mm Hg throughout the study. CONCLUSIONS: Difluprednate 0.05% four times daily is well tolerated and is noninferior to prednisolone acetate 1% eight times daily for the treatment of endogenous AU.
