Conditions
Brief summary
Comparison of Efficacy and Ocular Surface Disease Assessment between BRIDIN-T Eye drops 0.15% and ALPHAGAN-P Eye drops 0.15% in Glaucoma or Ocular Hypertensive Patients : Phase 4, Parallel Group Design, Investigator-blind, Active-control, Randomized, Multi-center Trial
Detailed description
Following 12 weeks of administration of BRIDIN-T Eye drops 0.15%(non preservative) or ALPHAGAN-P Eye drops 0.15%(preservatives) for patients with glaucoma or Ocular Hypertensive Patients. The use of BRIDIN-T Eye drops(non preservative) is less harmful to external ophthalmicus diseases and increase of medication compliance for ophthalmic drugs than the ALPHAGAN-P Eye drops 0.15%(preservatives)

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Corneal staining test | Administered 12 weeks after | The degree of staining of the cornea after blue fluorescein staining under the slit lamp illumination of a cobalt blue light source using a yellow filter was evaluated on a 6 point scale according to the oxford grading system |
| Conjunctival staining test | Administered 12 weeks after | After lysamine green staining under slit lamps, the conjunctiva was divided into the nasal side and the lateral side, and the degree of nasal conjunctiva and bilateral conjunctival staining was evaluated on a 6-point scale according to the oxford grading system |
| Ocular surface disease index (OSDI) | Administered 12 weeks after | The ocular surface disease index was assessed for ocular surface disease, including visual function (five items), eye symptoms (four items), and environmental factors (three items) , 0 point for no symptoms, 1 point for occasional symptoms, 2 points for symptoms of half a day, 3 points for most symptoms, and 4 points for symptoms during the whole day. |
| Questionnaire (Evaluation of Satisfaction with Medication, Ocular tolerance) | Administered 12 weeks after | The evaluation of satisfaction with medication is conducted with a questionnaire evaluation on the convenience of use, storage of investigational product, and the ocular tolerance. Evaluation is conducted on 8 symptoms of tingling/hot, sticky, itchy, blurred vision, foreign body sensation, dryness, glare, and pain. Assess the severity of symptoms (0-3 points) and duration of symptoms (immediate, continuous) |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Tear break up time (TBUT) | Administered 4, 12 weeks after | After blinking blue fluorescein staining of the cobalt blue light source using a yellow filter, it was observed from the blinking point that there was a black spot, a streak pattern or a fluorine defect in the fluorescein-tear layer Was measured in seconds. The measurement results were repeated three times and average values were used. |
| Corneal staining test | Administered 4 weeks after | The degree of staining of the cornea after blue fluorescein staining under the slit lamp illumination of a cobalt blue light source using a yellow filter was evaluated on a 6 point scale according to the oxford grading system |
| Slit Lamp Biomicroscopy Findings - Limbal Redness | Administered 4, 12 weeks after | Slit lamp Biomicroscopy findings will be assessed on Efron Grading scales scored to the nearest 0.1 on a scale of 0 - 4 (0=normal, 1=trace, 2=mild, 3=moderate, 4=severe). |
| Conjunctival staining test | Administered 4 weeks after | After lysamine green staining under slit lamps, the conjunctiva was divided into the nasal side and the lateral side, and the degree of nasal conjunctiva and bilateral conjunctival staining was evaluated on a 6-point scale according to the oxford grading system |
| Ocular surface disease index (OSDI) | Administered 4 weeks after | The ocular surface disease index was assessed for ocular surface disease, including visual function (five items), eye symptoms (four items), and environmental factors (three items) , 0 point for no symptoms, 1 point for occasional symptoms, 2 points for symptoms of half a day, 3 points for most symptoms, and 4 points for symptoms during the whole day. |
| IOP(Intraocular pressure) | Administered 4, 12 weeks after | IOP (fluid pressure inside the eye) was assessed using Goldmann applanation tonometry and measured in millimeters of mercury (mmHg). Data at 10:00 AM from Weeks 4, 8, and 12 were pooled. A more negative change indicates a greater amount of improvement. One eye (study eye) was subject to analysis. |
