Drainage tube implants are also implicated in treatment of uveitic and inflammatory glaucoma.Minimally invasive glaucoma surgery is performed in order to overcome the risks and adverse effects associated with conventional surgical procedures. However, there are limited studies testing the efficacy of utilising this type of surgery for the treatment of uveitic glaucoma.In addition to the direct reduction of IOP, surgical procedures are used to remove blood, viscoelastic fluid and debris in glaucoma caused by cataract extraction and ocular trauma. They may also be utilized to remove depot steroids in corticosteroid glaucoma and ghost cells from the vitreous humour in ghost-cell glaucoma through a procedure known as vitrectomy. == References ==
