At present one of optimum methods of treatment of the second glaucoma is setting of AGV. We want to report about applications of AGV at second glaucoma as a result of the closed globe eye trauma. Case 1: Under the observation there was a patient with lens subluxation, 1 degree. The visual acuity was 20/20, initial narrowing of visual field only. In spite of maximum antihypertensive therapy IOP was 39-45 mm Hg. Setting of AGV on a standard method allowed to lower IOP and preserve vision, avoid cataract surgery on an eye with high IOP. Case 2: We looked after a patient with lens luxation into the vitreous body, haemophthalmus, Berlin\'27s edema and detachment of inferior part of retina with a giant tear from ora serrata. The baseline visual acuity was 0,001. After encircling scleral buckling (ESB) and vitreoretinal surgery the visual acuity was 6/200 with an aphakic correction. In spite of maximum antihypertensive therapy IOP was 36–39 mm Hg. There was persistent corneal erosion .We set a valve behind ESB, conducted a drainpipe under ESB and entered it in a anterior chamber standard. IOP was normal. Setting of AGV allowed to get the visual acuity equal 4/20 with an aphakic correction and attain corneal epithelization. Follow-up period was 11 months (case 1) and 7 months (case 2). Application of AGV is the effective method of treatment of posttraumatic glaucoma, normalizing IOP without drops, including complicated cases.
