Inclusion Criteria

Each patient MUST:
1.Be willing and able to provide informed consent either written, or if the patient is not able to read, provide consent as stipulated by local laws and Human Research Ethics Committee (HREC) guidelines.
2.Be willing and able to follow all instructions and attend all study visits.
3.Have a clinical diagnosis of suspected acute adenoviral conjunctivitis in at least 1 eye and the presence of both of the following minimal clinical signs in that same eye:
•Bulbar conjunctival redness: a minimum grade of ‘1’ on 0-3 scale
•Watery ocular discharge: a minimum grade of ‘1’ on a 0-3 scale
4.Patient reported presence of signs and symptoms consistent with adenoviral conjunctivitis equal to or less than 3 days in same eye prior to Visit 1.
5.Have a positive AdenoPlus® test at Visit 1 in the same eye that meets the minimum 1+ grade for bulbar conjunctival redness and watery ocular discharge.
6.Be willing to discontinue contact lens wear for the duration of the study.

Exclusion Criteria

Each patient MUST NOT:
1.Have known sensitivity or poor tolerance to any component of the study medications or diagnostics.
2.Have a history of ocular surgical intervention or trauma within 12 weeks prior to Visit 1 or planned for the period of the study.
3.Have presence of any active ocular inflammation (e.g., uveitis, allergic conjunctivitis, ocular rosacea, or iritis), other than acute adenoviral conjunctivitis.
4.Have clinical signs or presence of an ocular infection other than acute adenoviral conjunctivitis (e.g., bacterial, fungal or other ocular viral infection, such as herpes).
5.Have the presence of corneal subepithelial infiltrates at baseline.
6.Have a history of recurrent corneal erosion syndrome, ulcerative keratitis or dry eye, including meibomian gland dysfunction and other ocular surface diseases.
7.Have presence of blepharitis, lid abnormality, significant inflammation of the lid margin, or ptosis.
8.Have lacrimal duct obstruction in either eye.
9.Have presence of any other clinically significant findings during the slit lamp exam that may interfere with study parameters or otherwise confound the data as determined by the investigator
10.Have any clinically significant retinal or optic nerve findings (as observed in the non-dilated fundus exam) or prior diagnoses in either eye that may interfere with study parameters or otherwise confound the data as determined by the investigator).
11.Have used any topical ocular or systemic anti-viral or topical ocular or systemic corticosteroid within 7 days of enrollment and do not plan to start any topical ocular or systemic anti-viral during study duration. Inhaled, intranasal, and topical dermatologic steroids (except on the face) are allowed during the study.
12.Initiate or continue the use of warm or cold compresses for the duration of the trial.
13.Have used any topical ophthalmic solutions, including tear substitutes and diagnostics, within 2 hours of Visit 1 and be unable to discontinue all topical ophthalmic solutions (including diagnostics, except as required by this protocol and antibiotics) for the duration of the study. In addition, if the patient has used an artificial tear or other topical ophthalmic formulated in a hydrogel within the past 72 hours.
14.Be currently pregnant, nursing, or planning a pregnancy; or be a woman that has a positive pregnancy test.
15.Have any uncontrolled (not on a stable regimen for the past 30 days) systemic disease or debilitating disease (e.g., cardiovascular disease, hypertension, diabetes, or cystic fibrosis) or taking medications known to impact the ocular surface and/or tear film.
16.Have a planned overnight hospitalization during the period of the study.
17.Have any uncontrolled (not on a stable regimen for the past 30 days) autoimmune disease or taking medications known to impact the ocular surface and/or tear film.
18.Have prior (within 30 days of beginning study treatment) or anticipated concurrent use of an investigational drug or device.
19.Have a condition or a situation which, in the investigator’s opinion, may put the patient at increased risk, confound study data, or interfere significantly with the patient’s study participation.
20.Be unlikely to follow study instructions or to complete all required study visits or has a condition or situation that in the investigator's opinion, may put the patient at significant risk, may confound the study results, or may interfere significantly

Study & Design

• Study Type: Interventional
• Study Design: Not specified

Primary Outcome Measures

Name	Time	Method
Mean change from baseline in viral titre levels in the study eye at Visit 3. Viral titre levels are assessed by a quantitative viral plaque-forming unit (PFU) assay used to measure the amount of infectious virus. This cell culture based technique is considered the gold standard for quantifying the living viral burden and will be determined from individual eye swabs.[Visit 3 (Day 7 +/- 1 day) ]
