Laroche D; Nkrumah GAmerican journal of ophthalmology case reports 2020; 18: 100617
PURPOSE: To report a case of refractory open angle glaucoma (POAG) in an osteogenesis imperfecta patient who was successfully treated with combination microinvasive glaucoma surgery: combined kahook blade goniotomy and ciliary sulcus suprachoroidal microtube insertion. OBSERVATION: A 57-year-old woman with a history of osteoporosis, breast cancer, osteogenesis imperfecta, with uncontrolled POAG in right more than left. Anterior segment examination revealed thin blue sclera, the optic nerve examination revealed glaucomatous cupping with cup to disc ration of 0.9 in right and 0.7 in left. Her IOP on six (6) medications was 26 mmHg in the right eye. After discussion of the risks and benefits, she agreed to undergo combined kahook blade goniotomy and ciliary sulcus suprachoroidal microtube insertion surgery to lower her intraocular pressure. Her IOP at 6 months follow up was 13 in the right eye and a decrease number of medications from six (6) to three. CONCLUSION AND IMPORTANCE: Patients with OI have homogenously thinner sclera and conjunctiva which pose a challenge to traditional subconjunctival surgical methods. Combined kahook blade goniotomy and ciliary sulcus suprachoroidal microtube insertion surgery are bleb sparing operations that enhances aqueous outflow to the aqueous veins and supraciliary space to lower intraocular pressure.
