JAMA Feb 2023Early onset of myopia is associated with high myopia later in life, and myopia is irreversible once developed. (Randomized Controlled Trial)
Randomized Controlled Trial
IMPORTANCE
Early onset of myopia is associated with high myopia later in life, and myopia is irreversible once developed.
OBJECTIVE
To evaluate the efficacy of low-concentration atropine eyedrops at 0.05% and 0.01% concentration for delaying the onset of myopia.
DESIGN, SETTING, AND PARTICIPANTS
This randomized, placebo-controlled, double-masked trial conducted at the Chinese University of Hong Kong Eye Centre enrolled 474 nonmyopic children aged 4 through 9 years with cycloplegic spherical equivalent between +1.00 D to 0.00 D and astigmatism less than -1.00 D. The first recruited participant started treatment on July 11, 2017, and the last participant was enrolled on June 4, 2020; the date of the final follow-up session was June 4, 2022.
INTERVENTIONS
Participants were assigned at random to the 0.05% atropine (n = 160), 0.01% atropine (n = 159), and placebo (n = 155) groups and had eyedrops applied once nightly in both eyes over 2 years.
MAIN OUTCOMES AND MEASURES
The primary outcomes were the 2-year cumulative incidence rate of myopia (cycloplegic spherical equivalent of at least -0.50 D in either eye) and the percentage of participants with fast myopic shift (spherical equivalent myopic shift of at least 1.00 D).
RESULTS
Of the 474 randomized patients (mean age, 6.8 years; 50% female), 353 (74.5%) completed the trial. The 2-year cumulative incidence of myopia in the 0.05% atropine, 0.01% atropine, and placebo groups were 28.4% (33/116), 45.9% (56/122), and 53.0% (61/115), respectively, and the percentages of participants with fast myopic shift at 2 years were 25.0%, 45.1%, and 53.9%. Compared with the placebo group, the 0.05% atropine group had significantly lower 2-year cumulative myopia incidence (difference, 24.6% [95% CI, 12.0%-36.4%]) and percentage of patients with fast myopic shift (difference, 28.9% [95% CI, 16.5%-40.5%]). Compared with the 0.01% atropine group, the 0.05% atropine group had significantly lower 2-year cumulative myopia incidence (difference, 17.5% [95% CI, 5.2%-29.2%]) and percentage of patients with fast myopic shift (difference, 20.1% [95% CI, 8.0%-31.6%]). The 0.01% atropine and placebo groups were not significantly different in 2-year cumulative myopia incidence or percentage of patients with fast myopic shift. Photophobia was the most common adverse event and was reported by 12.9% of participants in the 0.05% atropine group, 18.9% in the 0.01% atropine group, and 12.2% in the placebo group in the second year.
CONCLUSIONS AND RELEVANCE
Among children aged 4 to 9 years without myopia, nightly use of 0.05% atropine eyedrops compared with placebo resulted in a significantly lower incidence of myopia and lower percentage of participants with fast myopic shift at 2 years. There was no significant difference between 0.01% atropine and placebo. Further research is needed to replicate the findings, to understand whether this represents a delay or prevention of myopia, and to assess longer-term safety.

Review
Horner's syndrome arises from dysfunction of the oculosympathetic pathway and is characterized by miosis, enophthalmos, protrusion of the third eyelid, and ptosis. It has been recognized in a wide variety of breeds and ages in small animal patients. The oculosympathetic pathway is a 3-neuron pathway. The central/first order neuron arises from the hypothalamus and extends down the spinal cord. The preganglionic/second order neuron arises from the first 3 thoracic spinal cord segments and travels through the thorax and cervical region until it synapses at the cranial cervical ganglion. The postganglionic/third order neuron travels from this ganglion to the orbit. Topical application of cocaine is the gold standard for differentiating Horner's syndrome from other causes of miosis. Topical 1% phenylephrine allows for identification of a post-ganglion Horner's syndrome. Numerous etiologies have been reported for Horner's syndrome, but idiopathic disease is most common. Ancillary diagnostics include otoscopic examination, thoracic radiographs, or advanced imaging. Treatment and prognosis are determined by the etiology.

Ophthalmology Oct 2023To evaluate the safety and efficacy of lotilaner ophthalmic solution 0.25% compared with vehicle for the treatment of Demodex blepharitis. (Randomized Controlled Trial)
Randomized Controlled Trial
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.

IMPORTANCE
Dry eye disease (DED) is a common public health problem with significant impact on vision-related quality of life and well-being of patients. Medications with rapid onset of action and a good tolerability profile remain an unmet need.
OBJECTIVE
To assess efficacy, safety, and tolerability of a water-free cyclosporine ophthalmic solution, 0.1% (CyclASol [Novaliq GmbH]), applied twice daily in DED compared with vehicle.
DESIGN, SETTING, AND PARTICIPANTS
CyclASol for the Treatment of Signs and Symptoms of Dry Eye Disease (ESSENCE-2) was a phase 3, multicenter, randomized, double-masked, vehicle-controlled clinical study conducted from December 5, 2020, to October 8, 2021. Following a 14-day run-in period with an artificial tear administered 2 times per day, eligible participants were randomly assigned 1:1 to the treatment groups. Patients with moderate to severe DED were included in the study.
INTERVENTIONS
Cyclosporine solution vs vehicle administered 2 times per day for 29 days.
MAIN OUTCOMES AND MEASURES
The primary end points were changes from baseline in total corneal fluorescein staining (tCFS; 0-15 National Eye Institute scale) and in dryness score (0-100 visual analog scale) at day 29. Conjunctival staining, central corneal fluorescein staining, and tCFS responders were also assessed.
RESULTS
A total of 834 study participants were randomly assigned to cyclosporine (423 [50.7%]) or vehicle (411 [49.3%]) groups at 27 sites. Participants had a mean (SD) age of 57.1 (15.8) years, and 609 (73.0%) were female individuals. The majority of participants self-identified in the following race categories: 79 Asian (9.5 %), 108 Black (12.9%), and 635 White (76.1%). Participants treated with cyclosporine solution had greater improvement in tCFS (-4.0 grades) than the vehicle group (-3.6 grades) at day 29 (change [∆] = -0.4; 95% CI, -0.8 to 0; P = .03). The dryness score showed treatment benefits from baseline in both groups: -12.2 points for cyclosporine and -13.6 points for vehicle (∆ = 1.4; 95% CI, -1.8 to 4.6; P = .38). In the cyclosporine group, 293 participants (71.6%) achieved clinically meaningful reductions of 3 grades or higher in tCFS vs 236 (59.7%) in the vehicle group (∆ = 12.6%; 95% CI, 6.0%-19.3%; P < .001). These responders showed greater improvement in symptoms at day 29 including dryness (∆ = -4.6; 95% CI, -8.0 to -1.2; P = .007) and blurred vision (Δ = -3.5; 95% CI, -6.6 to -4.0; P = .03) compared with nonresponders.
CONCLUSIONS AND RELEVANCE
The ESSENCE-2 trial confirmed that treatment with a water-free cyclosporine solution, 0.1%, results in early therapeutic effects on the ocular surface compared with vehicle. The responder analyses suggest that the effect is clinically meaningful in 71.6% of participants in the cyclosporine group.

Randomized Controlled Trial
Lotilaner Ophthalmic Solution, 0.25%, for the Treatment of Demodex Blepharitis: Results of a Prospective, Randomized, Vehicle-Controlled, Double-Masked, Pivotal Trial (Saturn-1).
PURPOSE
The purpose of this study was to evaluate the safety and efficacy of lotilaner ophthalmic solution, 0.25%, compared with vehicle for the treatment of Demodex blepharitis.
METHODS
In this prospective, randomized, controlled, double-masked, phase 2b/3 clinical trial, 421 patients with Demodex blepharitis were randomly assigned in a 1:1 ratio to receive either lotilaner ophthalmic solution, 0.25% (study group), or vehicle without lotilaner (control group) bilaterally, twice daily for 43 days. Patients were evaluated at days 8, 15, 22, and 43. Outcome measures were complete collarette cure (collarette grade 0), clinically meaningful collarette cure (grade 0 or 1), mite eradication (0 mites/lash), erythema cure (grade 0), composite cure (grade 0 for collarettes/erythema), and drop comfort. Adverse events were also evaluated.
RESULTS
At day 43, the study group achieved a statistically significantly higher proportion of patients with clinically meaningful collarette cure (81.3% vs. 23.0%; P < 0.0001), complete collarette cure (44.0% vs. 7.4%; P < 0.0001), mite eradication (67.9% vs. 17.6%; P < 0.0001), erythema cure (19.1% vs. 6.9%; P = 0.0001), and composite cure (13.9% vs. 1.0%; P < 0.0001) than the control group. Nearly 92.0% of patients rated the study drop as neutral to very comfortable. All ocular adverse events in the study group were mild, with the most common being instillation site pain.
CONCLUSIONS
Twice-daily treatment with a novel lotilaner ophthalmic solution, 0.25% for 43 days, is safe and effective for the treatment of Demodex blepharitis compared with the vehicle control.

Ophthalmology Apr 2022To evaluate the efficacy and safety of OC-01 (varenicline solution) nasal spray for treatment of patients with dry eye disease. (Randomized Controlled Trial)
Randomized Controlled Trial
PURPOSE
To evaluate the efficacy and safety of OC-01 (varenicline solution) nasal spray for treatment of patients with dry eye disease.
DESIGN
Randomized, multicenter, double-masked, vehicle-controlled, phase 3 study.
PARTICIPANTS
Adults 22 years of age or older with a diagnosis of dry eye disease, artificial tear use, Ocular Surface Disease Index score of 23 or more, and Schirmer test score (STS) of 10 mm or less. Eligibility was not restricted by eye dryness score (EDS).
METHODS
Patients (N = 758) were randomized in a 1:1:1 ratio to twice-daily treatment with 50-μl intranasal spray in each nostril of OC-01 0.03 mg (n = 260), OC-01 0.06 mg (n = 246), or vehicle (control; n = 252) for 4 weeks (ClinicalTrials.gov identifier, NCT04036292).
MAIN OUTCOME MEASURES
The primary efficacy end point was the percentage of patients achieving a 10-mm improvement or more in STS at week 4. Secondary end points included change from baseline to week 4 in STS and EDS in a controlled adverse environment (CAE) chamber and in the clinic. Treatment-emergent adverse events (TEAEs) were assessed.
RESULTS
A statistically significantly greater percentage of patients achieved the primary end point in both OC-01 treatment groups compared with the vehicle group (OC-01 0.03 mg, 47.3%; OC-01 0.06 mg, 49.2%; vehicle, 27.8%; P < 0.0001 for both doses). Change from baseline in STS at week 4 was statistically significantly greater for patients receiving OC-01 than vehicle (P < 0.0001 for both doses). Eye dryness score assessed at week 4 improved with OC-01 treatment compared with vehicle, although the difference was not significant for EDS measured in the CAE chamber and showed (nominal) significance in the clinic. Overall, 86.5% of patients (654/756) reported at least 1 TEAE during the treatment period; most were mild, nonocular (sneezing, cough, throat irritation, and instillation site irritation) and were reported by fewer patients in the vehicle group than in the OC-01 treatment groups (OC-01 0.03 mg, 97.3%; OC-01 0.06 mg, 99.2%; vehicle, 57%).
CONCLUSIONS
OC-01 nasal spray was well tolerated and showed a clinically meaningful effect on signs and symptoms of dry eye disease.

Eye & Contact Lens Jun 2023To describe the labeling, packaging practices, and characteristics of compounded 0.01% ophthalmic atropine. (Randomized Controlled Trial)
Randomized Controlled Trial
OBJECTIVE
To describe the labeling, packaging practices, and characteristics of compounded 0.01% ophthalmic atropine.
METHODS
A convenience sample of parents of children who had previously been prescribed low-concentration atropine for myopia management were randomized to obtain 0.01% atropine ophthalmic solution from one of nine compounding pharmacies. The products were analyzed for various important quality attributes. The main outcomes were labeling practices, concentration of atropine and degradant product tropic acid, pH, osmolarity, viscosity, and excipients in 0.01% atropine samples obtained from nine US compounding pharmacies.
RESULTS
Twenty-four samples from nine pharmacies were analyzed. The median bottle size was 10 mL (range 3.5-15 mL), and eight of nine pharmacies used clear plastic bottles. Storage recommendations varied and were evenly split between refrigeration (33%), room temperature (33%), and cool, dark, dry location (33%). Beyond use dates ranged from 7 to 175 days (median, 91 days). Median pH of samples was 7.1 (range, 5.5-7.8). Median measured concentration relative to the prescribed concentration was 93.3% (70.4%-104.1%). One quarter of samples were under the 90% minimum target concentration of 0.01%.
CONCLUSIONS
An inconsistent and wide variety of formulation and labeling practices exist for compounding 0.01% atropine prescribed to slow pediatric myopia progression.

Review
Preservatives continue to be in widespread use in ophthalmic medications due to the convenience they provide, regulatory requirements and the higher cost of alternatives. Benzalkonium chloride (BAK) remains the most commonly used preservative but there is a trend towards the use of preservative-free (PF) drops for glaucoma, although at a higher price. An extensive body of literature explores BAK toxicity on ocular structures in animal and laboratory studies (in vitro and in vivo). Non-randomised controlled studies have provided some supporting evidence of its toxicity in patients, especially in those with pre-existing ocular surface disease (OSD) or on multiple medications. However, there have been very few randomised controlled trials that compare the same medication with and without BAK preservative. Several of these trials have never been published in any peer reviewed journals. Notwithstanding, those that have been published, have not demonstrated any clear benefits of the BAK-free formulations. Short duration and exclusion of those with OSD are limitations of these studies. There is a lack of evidence of clinically significant harm from a small number of BAK preserved drops in patients without OSD. This means that generally more expensive PF glaucoma medications should only be recommended for those on poly pharmacy or those with OSD but are not necessarily required for all patients.

Real-world treatment patterns of OTX-101 ophthalmic solution, cyclosporine ophthalmic emulsion, and lifitegrast ophthalmic solution in patients with dry eye disease: a retrospective analysis.
BACKGROUND
Dry eye disease (DED) is a disorder characterized by loss of tear film homeostasis that causes ocular surface inflammation and damage. The incidence of DED increases with age. Cyclosporine ophthalmic solution 0.09% (CEQUA; OTX-101), cyclosporine ophthalmic emulsion 0.05% (Restasis; CsA), and lifitegrast ophthalmic solution 5% (Xiidra; LFT) are anti-inflammatory agents indicated for DED. This analysis compared treatment patterns in patients with DED receiving OTX-101, CsA, or LFT.
METHODS
This real-world, retrospective, longitudinal cohort study utilized Symphony Health Integrated Dataverse claims from July 2019 to June 2021. The dataset included all patients with OTX-101 claims and patients with CsA or LFT claims randomly selected 2:1 to OTX-101. Patients were sorted into 3 cohorts based on index treatment. Index date was that of first treatment claim, and follow-up period was from index date to end of clinical activity or data availability. Time to treatment discontinuation (TTD), probability of discontinuation, and treatment persistence were assessed for OTX-101 vs. CsA, then OTX-101 vs. LFT. Subgroup analysis was performed based on age and prior DED treatment. Kaplan-Meier analysis and log-rank test were used to examine TTD. A logistic model evaluated association between index treatment and discontinuation. Unadjusted and adjusted odds ratios, 95% confidence intervals, and P-values were reported, with statistically significant associations based on P-values < 0.05.
RESULTS
Overall, 7102 patients (OTX-101 n = 1846; CsA n = 2248; LFT n = 3008) were eligible. Median TTD was 354 days for patients receiving OTX-101 vs. 241 days for CsA and 269 days for LFT. Log-rank test indicated TTD was significantly longer for patients on OTX-101 vs. CsA (P = 0.033). Patients on CsA were 35% more likely to discontinue treatment than patients on OTX-101; OTX-101 and LFT groups had similar discontinuation rates. After 360 days, 49.8% of patients receiving OTX-101 remained on treatment vs. 39.4% of patients on CsA (P = 0.036) and 44.0% of patients on LFT (P = 0.854).
CONCLUSIONS
Patients receiving OTX-101 remained on treatment significantly longer and were significantly less likely to discontinue treatment than patients on CsA. Older patients remained on OTX-101 significantly longer than CsA. These findings highlight treatment pattern differences in patients with DED receiving these anti-inflammatory agents.
