Description of intervention(s) / exposure
Patient presenting to the retina service with a fresh retinal tear would be invited to participate. Upon joining the study, an optical coherence tomography test would be done, then after laser therapy, the patient would be asked to follow up in one month. The optical Coherence tomography image of the retina is done specifically looking for an epiretinal membrane. This non invasive image of the fovea would be repeated on a monthly basis for 2 years.

Outcomes
Primary outcome [1] 306386 0
epiretinal membrane development by Optical coherence tomography. There is usually a hyper-reflective membrane at the inner surface of the retina. this is the start of a cellophane.
Timepoint [1] 306386 0
monthly images for 2 years
Secondary outcome [1] 348312 0
risk factors for epiretinal membrane formation: We will be looking at the tear location as described by the retina specialist. OCT would be done on a monthly basis to look at the possibility of an epiretinal membrane developing.
Timepoint [1] 348312 0
monthly assessment for 2 years
Secondary outcome [2] 348624 0
number of tears: This also would be retrieved from the patient's chart.
Timepoint [2] 348624 0
2 years; looking at the same monthly OCT.
Secondary outcome [3] 348848 0
Vitreous Hemorrhage; this will be retrieved from the patient's chart
Timepoint [3] 348848 0
this finding will be assessed on study entry only looking at the patient's chart.
Secondary outcome [4] 348849 0
Treatment Fashion
Timepoint [4] 348849 0
this will be assessed only on study entry looking at the patient's chart and the laser log.

Statistical methods / analysis
we are looking at the rate of epiretinal membrane formation after laser treatment for fresh peripheral retinal tears. A sample of 50 patients seemed adequate to catch a good number of epiretinal membrane and calculate risk factors. Bivariate analysis needed.

Summary
Brief summary
Epiretinal membrane is known to happen after laser surgery for a retinal tear. We look at the incidence using advanced imaging tools with high resolution. Patients presenting with a retinal tear will be invited to come on a monthly basis and get an image looking for an epiretinal membrane formation.
