  • ICG staining and complete removal of the ILM slows the rate of visual recovery but does not appear to have any long-term deleterious effect on the results of macular hole surgery. (johnshopkins.edu)
  • A case and discussion of macular hole management with medical therapy. (retina-specialist.com)
  • After this period of observation, best-corrected visual acuity remained 20/70 in the right eye and the macular hole persisted with an increase in the amount of IRF at the hole margins. (retina-specialist.com)
  • Given the small size of the macular hole, the absence of vitreomacular traction and the presence of IRF at the hole margin, we decided to start medical treatment, prescribing topical ketorolac 0.5% q.i.d. in the right eye. (retina-specialist.com)
  • The macular hole has remained closed. (retina-specialist.com)
  • These observations have led to a supplemental theory of macular hole formation: the hydration theory. (retina-specialist.com)
Chronic1
  • The value of testing macular function by central microperimetry in chronic CSC has been shown extensively. (entokey.com)
Located in the retina1
  • Neural factors that limit acuity are located in the retina, in the pathways to the brain, or in the brain. (wikipedia.org)
Pucker1
  • 6 In a recent study of eyes with idiopathic macular pucker using OCT/scanning laser ophthalmoscopy (SLO), vitreoschisis was detected in 42% (19/44) of the eyes. (arvojournals.org)

  • Samples were drinking water on attack and fatality rates of visual acuity and results of a slit- sent to the World Health Organization in hepatitis E epidemic in Somalia. (cdc.gov)
  • Anatomic and visual results. (nih.gov)
  • The main advantages of IRIS® Registry are its wide coverage and availability of diagnostic test results such as acuity values. (cdc.gov)
Posterior vitreous d1
  • In the limited vitrectomy group, a posterior vitreous detachment (PVD) was induced up till the equator as opposed to complete PVD induction till the vitreous base in the comparison group. (unime.it)
Patient's2
  • The decision to operate on the ERM was made based on a patient's macular symptoms and on his or her individual occupational or vocational needs. (entokey.com)
  • The recommended treatment plan is tailored based on each patient's symptoms, visual acuity and imaging studies. (gbretina.com)
Ranibizumab1
  • Anti-vascular endothelial growth factor (VEGF) has been the first choice in the treatment of wet age-related macular degeneration (AMD), since ranibizumab went on sale in 2006. (shsmu.edu.cn)
Photoreceptor1
  • Macular degeneration is the condition which occurs when the photoreceptor cells in the macula deteriorate. (braintomorrow.com)
