Brief Summary:
The investigators hypothesis is that using the micropulse laser in patient with Central Serous Chorioretinopathy (CSC) will prompt resolution of CSC and will be effective in significantly minimizing visual recovery time from this disease as well as potentially preventing recurrences.

Condition or disease Intervention/treatment Phase
Central Serous Chorioretinopathy Device: Micropulse Laser Treatment Other: No treatment Not Applicable

Detailed Description:
The investigators hypothesize that application of 577nm micropulse laser in patients with CSC will prompt resolution of CSC as measured by ocular coherence tomography and best corrected visual acuity. This will be a pilot study to establish sound methods and provide some insights to the safety and efficacy of CSC treatment.

Arm Intervention/treatment
Experimental: Micropulse Laser Treatment
Patient's randomized to ML treatment would be treated with the following settings: 200 micron spot size, 0.2 second duration, 15% duty cycle, and 300 milliWatt power. Their eyes would be dilated prior to treatment with standard mydriatic medications, including Tropicamide and Phenylephrine
Device: Micropulse Laser Treatment
Other Names:
  • Micropulse 577nm
  • Laser

Placebo Comparator: No Treatment
Patients randomized to this treatment arm, will not receive treatment for CSC. They will continue to be observed at month 1 and month 3. If any worsening of pathology is found during the follow up visits, the patient will be removed from the study and given appropriate standard of care by the attending
Other: No treatment

Primary Outcome Measures :
  1. Resolution of Fluid Build-up [ Time Frame: within 1 week to 3 months after the laser procedure is completed ]
    Central Serous Choroidopathy is a disease that causes fluid to build up under the retina,the back part of the inner eye that sends sight information to the brain. The objective here is to apply 577nm of micropulse laser to see if CSC resolution occurs and measuring it through ocular coherence tomography (retinal imaging), vision score, and visual field testing for retinal sensitivity.
