After my wife underwent NA Glaucoma Surgery (&Cataracts'surgery) her IOP remains at 5/6 mm in RE, since last 12 years. She suffers from Inflammation, pain & drupy eye-lid, but same is combated instilling lotepred LS & Vigamox for few days. This phenomenon is once in a year. Surgeon did autologous blood injection before 6/7 years as safe guard & also performs Dye test to ensure no leak from bleb. In Jan. 2017 her OCT was normal. On 6th Jan. 2018,OCT indicates Superior thickness loss in RE, with Progression (RFNL thickness loss. LE condition is normal in OCT (-having IOP at 18/20mmHg on instilling Xalacom/Travacom- once at night. To keep further low Timolet OD is added once in the morning. Ophthalmologist is well experienced in Glaucoma Surgery. He says since IOP in RE is low, nothing can be done, to arrest progression. Kindly this may be please replied by Glaucoma Specialist, if any intervention is available to sustain present vision.
