ABSTRACT We assessed the causes of visual impairment and blindness in 694 diabetic patients attending our eye centre in Sana'a, Yemen from 2001 to 2005 by review of their medical records. (who.int)
According to the World Health Organization definitions, 273 (39.3%) patients had visual impairment and 109 (15.7%) were blind. (who.int)
Cataract, proliferative diabetic retinopathy (PDR) and diabetic maculopathy were the main causes of visual impairment and blindness. (who.int)
Diabetic retinopathy is a public health problem in Yemen and national screening and educational programmes are highly needed to reduce the risk of visual impairment and blindness among diabetics. (who.int)
The prevalence of visual impairment cein angiography. (who.int)
For many patients, the visual impairment associated with AMD means a loss of independence, depression, increased financial concerns and the need to adapt to vision loss at a time when they are likely suffering from other debilitating conditions(1-5). (org.es)
Retina2
This enables us to have disease and affects many parts of the a stereoscopic view of the retina and its body, including the eye, leading to visual A retrospective observational study vasculature. (who.int)
E arly diagnosis of fungal endophthalmitis is important in order to prevent irreversible damage to the retina and prevent visual loss. (eophtha.com)

Effects of interocular blur suppression ability on monovision task performance" Schor C, Carson M, Peterson G, Suzuki J, Erickson P J Am Optom Assoc. 1989 Mar;60(3):188-92 "Visual acuity and optical parameters in progressive-power lenses" Villegas EA, Artal P Optom Vis Sci. (wikipedia.org)
[ 9 ] Deep stromal NV is serious, possibly leading to loss of optical transparency of the tissue and hence decrease visual acuity through stromal hemorrhage, scarring, and lipid deposition. (medscape.com)
Loss1
The natural history of dry AMD is progressive, with gradual loss of visual function that may span over many years time. (org.es)
Function1
Thus, lesions developing in this region can have a major impact on visual function. (org.es)
Patients1
RÉSUMÉ Nous avons évalué les causes des déficiences visuelles et de la cécité chez 694 patients diabétiques ayant consulté dans notre centre des soins oculaires à Sanaa (Yémen) entre 2001 et 2005 en examinant leur dossier médical. (who.int)
Blindness1
Research supported by these funds is directed toward reducing the personal and financial hardships caused by blindness and visual deprivation through improving our ability to prevent, diagnose, and treat blinding and disabling eye disorders. (nih.gov)
