What You Need to Know Before You Apply

What is the purpose of this trial?

This trial explores two methods to assist individuals with drooping upper eyelids (ptosis) in determining potential surgical benefits. It compares Phenylephrine eye drops, which temporarily lift the eyelid, with traditional eyelid taping (using adhesive tape on the upper eyelid) to assess which method better evaluates vision improvement. The trial seeks adults diagnosed with drooping eyelids who can tolerate eye drops. Participants should not have severe heart issues or use medications that interact poorly with Phenylephrine. As a Phase 4 trial, the treatment is already FDA-approved and proven effective, aiming to understand its benefits for more patients.

Will I have to stop taking my current medications?

The trial does not specify if you need to stop taking your current medications, but you cannot participate if you are taking certain drugs that should not be used with phenylephrine, like Ergot Derivatives, Iobenguane Radiopharmaceutical Products, Kratom, Lisuride, or Monoamine Oxidase Inhibitors.

What is the safety track record for these treatments?

Research has shown that phenylephrine 2.5% eye drops are generally safe for ocular use. These drops typically enlarge the pupil before eye exams or surgeries. While most people tolerate them well, some might experience temporary effects like eye irritation or redness.

Studies suggest that eyelid tape is safe for short-term use. However, long-term use might loosen the eyelid skin, potentially affecting eye health and complicating future eyelid surgery.

Overall, both treatments in this trial have established safety records. However, discussing any concerns with a healthcare professional is always advisable. ^{1 2 3 4 5}

Why are researchers enthusiastic about this study treatment?

Most treatments for drooping eyelids, like surgery or Botox injections, aim for long-term results but involve more invasive procedures. Researchers are excited about using Phenylephrine ophthalmic solution and eyelid taping because they offer non-invasive, quick fixes that can be administered easily. Phenylephrine works by temporarily tightening the muscles in the eyelid, lifting it without any need for incisions or injections. Meanwhile, eyelid taping provides an immediate, mechanical lift simply by holding the eyelid in place. These options promise faster relief and fewer risks than traditional methods.

What evidence suggests that this trial's treatments could be effective for drooping eyelid?

This trial will compare Phenylephrine 2.5% eye drops with eyelid tape for treating droopy eyelids. Research has shown that Phenylephrine can quickly lift droopy eyelids, with most people noticing a change within 10 minutes, making it a good non-surgical option for fast improvement. The trial also studies eyelid tape, which uses a thin sticky strip to lift the eyelid instantly. However, long-term use of eyelid tape might cause discomfort and alter eyelid shape. Both treatments are temporary, but Phenylephrine acts faster to lift droopy eyelids. ^{1 2 3 6 7}

What Are the Treatments Tested in This Trial?

Interventions

• Eyelid Tape
• Phenylephrine Ophthalmic

Trial Overview

The trial is testing if Phenylephrine eye drops are better than using tape to lift the eyelid for assessing how much ptosis blocks vision before eyelid surgery. Participants will try both methods so researchers can compare which predicts surgical outcomes best.

How Is the Trial Designed?

Group I: Phenylephrine and Eye Taping Group Experimental Treatment 2 Interventions

Participants in this group will initially have superior visual field testing done with the upper eyelid manually taped. Then, participants will have superior visual field testing done after receiving Phenylephrine 2.5% ophthalmic solution. Participants will be in each group for up to 60 minutes.

In a study of 100 diabetic patients with darkly pigmented irides, 10% phenylephrine was found to be significantly more effective than 2.5% phenylephrine for achieving pupil dilation, with mean pupil diameters of 7.40 mm versus 7.05 mm respectively.

Despite the increased efficacy of 10% phenylephrine, there were no significant differences in heart rate or blood pressure between the two concentrations, suggesting that while 10% is more effective, the 2.5% concentration may be safer for patients with significant vascular disease or autonomic dysfunction.

The oxazolidine prodrug of phenylephrine demonstrated equal mydriatic (pupil-dilating) activity to phenylephrine HCl but achieved maximum effect 60 minutes earlier, suggesting a faster onset of action.

Suspending the base form of phenylephrine in sesame oil resulted in greater mydriatic activity compared to equimolar concentrations of phenylephrine HCl, likely due to a pH change in tear fluids that enhances absorption.

In a pooled analysis of 131 subjects from two Phase III trials, the fixed-combination mydriatic TR-PH showed significantly greater pupil dilation compared to its individual components (tropicamide and phenylephrine) and placebo, with changes of 0.58 mm, 3.87 mm, and 4.65 mm respectively (all p < 0.0001).

The treatment was found to be safe and well-tolerated, with adverse events being infrequent, transient, and mostly mild.

The novel phenylacetyl ester derivative of phenylephrone demonstrated a stronger mydriatic effect than phenylephrine and was effective without causing irritation to the rabbit eye, indicating its potential as a safe short-term eye treatment.

Unlike phenylephrine, which showed systemic circulation after topical application, the phenylacetyl ester resulted in localized activity with no traces of phenylephrine in the bloodstream, suggesting a safer profile for ocular use.

Mydriasert, an ophthalmic insert containing tropicamide and phenylephrine, provides adequate mydriasis for retinal angiography in both diabetic and nondiabetic patients, with similar efficacy to traditional eyedrops.

The use of Mydriasert is associated with a lower total drug dose, which may reduce the risk of cardiovascular side effects, while no severe adverse effects were observed in either treatment group.

In a phase 3 study involving 758 adults with dry eye disease, OC-01 nasal spray significantly improved tear production compared to a placebo, with 47.3% and 49.2% of patients in the OC-01 treatment groups achieving a 10-mm improvement in Schirmer test scores at week 4.

OC-01 was well tolerated, with most treatment-emergent adverse events being mild and nonocular, although a higher percentage of patients in the OC-01 groups reported side effects compared to the vehicle group.

The TPD ophthalmic solution, which combines tropicamide, phenylephrine, and diclofenac, effectively maintains pupil dilation (mydriasis) during cataract surgery, showing similar results to the standard T, P, and D solution.

In a study involving 25 eyes from 19 patients, both solutions resulted in comparable pupil diameters before and after surgery, indicating that TPD is as effective as the traditional combination for facilitating the surgical procedure.

Dipivefrin (Propine) is effective in lowering eye pressure in glaucoma patients, but it has been associated with a high incidence of follicular conjunctivitis, leading to discomfort in some cases.

Withdrawal of dipivefrin typically resolves the conjunctivitis, but symptoms may return with other similar medications, highlighting the need for regular eye examinations to catch this side effect early.

Phenylephrine hydrochloride is an effective and relatively safe drug for ophthalmic use, but caution is advised due to potential severe cardiovascular side effects, especially in patients with pre-existing conditions like cardiac disease or hypertension.

The 2.5% concentration of phenylephrine is generally safe for use in infants and the elderly, while the 10% concentration should be used carefully and is contraindicated in patients with narrow-angle glaucoma or those on certain antidepressants.

In a study of 60 patients with primary open-angle glaucoma undergoing cataract surgery, Mydrane® provided stable pupil dilation comparable to Mydriasert® and topical eye drops, indicating its effectiveness as a mydriatic agent.

All three methods of pupil dilation resulted in similar surgery durations and maintained stable anterior chamber configurations postoperatively, suggesting that Mydrane® is a safe and effective option for facilitating cataract extraction.

While MY took longer to achieve maximal dilation than PT drops, it provided comparable dilation levels during cataract surgery, indicating its safety and efficacy as an alternative method for pupil dilation.
