SDOCT imaging to identify macular pathology in patients diagnosed with diabetic maculopathy by a digital photographic retinal screening programme.

Introduction: Diabetic macular edema (DME) is an important cause of vision loss. England has a national systematic photographic retinal screening programme to identify patients with diabetic eye disease. Grading retinal photographs according to this national protocol identifies surrogate markers for DME.

Postural variation in intraocular pressure in primary chronic autonomic failure.

Patients with syndromes of generalised autonomic failure often have extreme posture-related lability of blood pressure, with both orthostatic hypotension and recumbent hypertension. Whether these changes influence intraocular pressure (IOP) is not known. Mean arterial pressure (MAP) and IOP were measured in response to variations in posture between +45 degrees and -20 degrees in 8 normal subjects and 9 subjects with primary generalised chronic autonomic failure (AF).
