Purpose G‐probe cyclophotocoagulation(IRIDEX laser systems) on blind eyes has allowed us to develop differentiated approaches to the treatment considering the etiology and optimum dosages.The objective we had defined was to utilize the accumulated experience and apply the given technique also on eyes with visual acuity. Methods During 3 years there were 10 eyes under our supervision with neovascular glaucoma after diabetic retinopathy or vein thromboses.IOP was 45.4 mmHg.In 9 cases visual acuity as light perception;1 patient had account of fingers on distance 50cm without correction.2 patients had undergone vitrectomy.Technique:position‐supine; anaesthesia retrobulbar injection Sol.Lidocaine 2%‐3.0;optimum dosages (power‐duration‐number of coagulants):NVG after vein thromboses:1000‐1750mW(inclusive)‐1000msec‐minimum 24;NVG after diabetic retinopathy:1750‐2500mW‐2000msec‐minimum 25.After TSCPC subconjunctival steroids injection was done. Results Visual acuity after TSCPC at 8 patients increased to account of fingers on distance 1m;1 case‐account of fingers on distance 2m;1 case‐account of fingers on distance 2m with correction (+4.0D)20/200.In 3 cases ? year after the condition had stabilized, we performed glaucoma surgery,in 1 case combined operation‐cataract and glaucoma surgery,in 1 case‐panretinal photocoagulation.All patients were under dynamic supervision.IOP after 3 years was 23.5 mmHg.1 patient after TSCPC and glaucoma surgery is preparing to keratoplasty. Conclusion The results received by us are quite encouraging in terms of stabilization of intraocular pressure, painful syndrome, and also preservation of vision acuity.The given technique can be recommended as preparatory for the subsequent interventions for "refractory" patients.
