title: Refractory secondary glaucoma-clinical case.
abstract: OBJECTIVE
  The major objective of treatment in glaucomatous disease is the decrease of intraocular pressure while maintaining the patient's vision and quality of life. Despite therapeutic possibilities, some cases of glaucoma remain refractory to treatment with the maintenance of elevated intraocular pressure and further progression of the disease.Artificial drainage systems, Ahmed valve, is a treatment alternative for refractory glaucoma when medical therapy, laser or conventional surgery have shown no results.
  
  
  RESULTS
  We present the case of a patient presenting with refractive to medical treatment secondary glaucoma, following cataract surgery and vitrectomy for retinal detachment.
  
  
  CONCLUSIONS
  One of the complications of vitreoretinal surgery is secondary glaucoma. Some of the patients with this type of glaucoma are unresponsive to conventional medical therapy. In such situations, a DPS implantation is needed such as an Ahmed valve in our case. There are situations in which classical surgery-trabeculectomy--has no theoretical chance of success (in cases of neovascular glaucoma, secondary glaucoma, and inflammatory glaucoma post vitreoretinal surgery), [5,6]. Even though ASD are only used for refractory glaucoma, in this type of glaucoma, ADS can be used successfully as first line surgery.
