Evaluation of Performance and Safety of Carbopol 980 NF 0.2%- Based Medical Device in the Management of Patients With Glaucomar or Ocular Hypertension and Concomitant Dry Eye Syndrome on Multiple Long-term Topical Hypotensive Therapy

Inclusion criteria

• ✓. Have an age ≥ 18 years,;
• ✓. Have undergone the informed consent process and have signed an approved consent form;
• ✓. Are able to comprehend the full nature and the purpose of the investigation, including possible risks and side effects, and subjects able to cooperate with the Investigator and to comply with the requirements of the entire investigation (including ability to attend all the planned investigation visits according to the time limits), based on Investigator's judgement;
• ✓. Have a diagnosis of glaucoma or Ocular Hypertension (OHT). Diagnosis of glaucoma will be based on: optic disc assessment, measurement of the retinal nerve fiber layer and neuroretinal rim with optical coherence tomography (OCT); characteristic repeatable visual field defects defined as a pattern standard deviation (PSD) with P \< 0.05, and/or glaucoma hemifield test (GHT) results outside normal limits. Diagnosis of OHT will be based on history of IOP (intraocular pressure) \> 21 mmHg in at least two occasions and normal optic disc and Humphrey visual field test;
• ✓. Are receiving an ongoing topical therapy with two or more preserved ocular hypotensive agents (e.g. beta-blockers, alpha-agonists, carbonic anydhrase inhibitors, prostaglandins) for at least 6 months and are willing to continue these treatments at unchanged dose for the entire investigation duration;
• ✓. Have a diagnosis of moderate to severe DES performed through the following exams: slit lamp examination (SLE), tear (lacrimal) meniscus exam, Schirmer's test, Tear Film Break-Up Time (TFBUT), fluorescein staining of the cornea and conjunctiva (Oxford Staining Scheme). Please note that a diagnosis of DES may be performed at entry in the investigation;
