Abstract Details


To report a case of alteration in corneal biomechanical properties associated with osteogenesis imperfecta


We describe a case of a sixty year-old woman with osteogenesis imperfecta diagnosed 10 years ago


The patient presented with a visual acuity of 10/10 in each eye, and anterior segment examination revealed blue sclera and pronounced arcus senilis.


Corneal-compensated intraocular pressure was 18,4 mmhg in the right eye (RE) and 19,4 mmhg in the left eye (LE). Corneal hysteresis reading was 7,1mmhg in the RE and 5,4 mmhg in the LE, and corneal resistance factor was 7,2 mmhg in the RE and 5,4 mmhg in the LE. The central corneal thickness was 408um in the RE and 397um in the LE.


Likewise decreased of central corneal thickness, decreased values of corneal hysteresis and corneal resistance factor can represent additional risk factors for glaucoma in this patient and maybe in others patients with osteogenesis imperfecta
