Methods, systems, and compositions for maintaining functioning drainage blebs to reduce intraocular pressure (IOP) of an eye being treated for glaucoma. The methods, systems, and compositions feature the combination of a minimally invasive micro sclerostomy (MIMS) procedure and the application of beta radiation to a target area. The beta radiation can function to inhibit or reduce the inflammation and/or fibrogenesis that typically occurs after a MIMS procedure and leads to hole and/or bleb failure. By reducing inflammation and/or fibrogenesis, the MIMS holes and/or blebs can remain functioning appropriately.
