Workup

  • Four months after he was first put on steroids, and after another failed taper, he underwent a vasculitis workup—including a temporal artery biopsy—that was normal. One week later, he experienced an acute decline in vision in his left eye.[aao.org]

Treatment

  • There is an increasing demand for new visual function tests that are more sensitive than current standards to monitor disease progression and to evaluate treatment effect.[iovs.arvojournals.org]
  • TREATMENT: Reducing inflammation with the use of steroids. Treatment is with high dose systemic steroids and steroid eyedroppers. Treatment of the secondary complications are via surgery.[ct.gov]

Prognosis

  • PROGNOSIS: If left untreated, the cornea will rupture and blindness will occur. Prognosis is good with keratoplasty and corneal transplants. May require optical aids and will require use of sunglasses in bright light.[ct.gov]

  • Clinical course and prognosis: Retinitis pigmentosa is chronically progressive.[alpfmedical.info]
  • Prognosis Retinal detachments often cause some degree of permanent visual field or central visual acuity loss, even after successful retinal reattachment.[willseye.org]
  • Prognosis GFS has a progressive course. In most cases, visual loss occurs in the first two decades of life. Some improvement of visual acuity has been reported after treatments with cyclosporin A and bromocriptine.[orpha.net]

Etiology

  • Etiology Mutations in the NR2E3 gene (formerly called PNR ) have been identified in some patients with GFS. NR2E3 (15q23) encodes a retinal nuclear receptor that is involved in the differentiation of photoreceptors.[orpha.net]
  • PROGNOSIS: Visual impairment varies depending upon the etiology of the of the disease. Vision loss may be a slow progression to blindness.[ct.gov]
  • Therefore, metabolic and hereditary etiologies should be considered.[jamanetwork.com]

  • The pathophysiology of MELAS is incompletely understood but relates broadly to insufficient energy production through the oxidative phosphorylation pathway.[jamanetwork.com]

Prevention

  • There are also a range of treatments aimed at preventing and reversing neovascularisation. These are effective in preventing further vision loss, and in some cases partially restoring vision.[myvmc.com]
  • The name derives from the Greek katarraktês , which means "something that falls from top to bottom", to express the idea of a screen that prevents the eye from seeing when the lens becomes opaque.[sifigroup.com]

  • Such techniques should not just complement conventional medicine, write the authors, but they should also be used preventively.[medicalnewstoday.com]
  • Prevention and Treatment If a retinal break or tear is detected before there is retinal detachment, laser or cryotherapy (freezing) to the retinal tear is often successful in sealing the tear and preventing a retinal detachment.[willseye.org]
