anti-inflammatory properties). Antimitotic agents Antimitotic agents are used mainly when a cyst is resistant to all other treatments apart from surgery, since surgery is the last resort. Antimitotic agents are injected into the cyst and left inside for 5 minutes; after 5 minutes the agents are rinsed out. Antimitotic agents have the side effect of creating a small inflammation which can easily be treated with topical steroids. Antimitotic agents stop the mitose of the cells of the cyst by interfering with a particular phase of the cell cycle, which stops the cyst from growing and will eventually kill the cells and thus the cyst. Laser therapy Laser therapy is a treatment which has to be repeated several times. The treatment gets repeated every week until the cyst is gone. Despite not having the highest success rate it is nowadays the most preferred treatment against iris cyst because it is the least invasive method since the eye doesn't need to be punctured or cut. Two kinds of laser beams can be used for laser therapy: thermal (diode or argon laser) and Nd:YAG laser. Sometimes both methods are combined for a better result since thermal laser can harden the cyst and stop the intracystic fluid production and Nd:YAG can perforate the cyst membrane and drain the cyst. Surgical Surgery is considered to be the last resort because surgery has the highest chance at complications. The surgical approach depends on where the cyst is located, how big the cyst is and the number of cysts. The stepwise minimally invasive strategy There are many options when treating an iris cyst. Mentioned above are the most used treatments but in the past there have been other methods but they haven't been successful enough to be still used today. A clinician has to consider a lot of things when choosing a treatment. The golden rule when treating iris cysts however is to choose the least invasive method. That means that cysts which are not causing any problems will not be treated but observed. The least invasive treatment is laser therapy and is, therefore, also the preferred method to treat an iris cyst. Depending on the kind of cyst, the clinician will choose either antimitotic agents or AS-OCT, if laser has failed or if laser is not possible. It is unlike that FNA will be used due to its low potential for removing the cyst. Surgery is
