Is the Reduction in IOP After Treatment of 180 Degrees Equivalent to Treatment of 360 Degrees With SLT?

Potential patients will be identified by the Principal Investigator during a clinic visit. Pre‐screening criteria is carried out by the co‐investigator or the research co‐ordinator. General eligibility criteria, inclusion and exclusion criteria are applied. The Research Co‐ordinator approaches the patient and the SLT laser study is discussed with the patient. The patient is provided the Information Sheet and advised to contact the Research Coordinator if they wish to proceed. Informed consent is obtained if the patient wishes to proceed. Baseline data is collected and the right eye is randomised with the fellow eye to receive non randomised treatment. SLT is performed in both eyes (180 degrees in 1 eye + 360 degrees in the fellow eye) during an office visit. IOP in both eyes is checked and recorded at one hour post treatment. The patient returns for follow up at two weeks post SLT treatment visit. A complete ocular examination, including IOP, is undertaken. Complications and adverse events are assessed and recorded. Any change to eyedrops is recorded. Patients return at one, three and six months for review, and the same assessment as above is undertaken at each visit. Enrolling is complete when 48 patients are enrolled. Patients are advised enrolling is complete. Statistical analysis is undertaken to assess the mean change in IOP between the two treatments. Complications and adverse events are each treatment group are recorded. The study is submitted for publication and written communication is provided to each enrolled patient.
