Scleromalacia


Presentation

  • It was particularly advantageous when large scleral defects or conjunctival scarring was present. With these therapeutic results, preserved scleral graft with AMT qualifies as a new treatment alternative for scleromalacia.[ncbi.nlm.nih.gov]
  • Etiology Unknown Clinical Presentation Patients with scleromalacia perforans present with deep scleral ulcerations. These scleral ulcerations coalesce, and the thinned sclera shows a bluish color from the underlying uveal tissue.[link.springer.com]
  • She presented to us with pronounced eye manifestation which on further inquiry and investigation was found to be associated with rheumatoid arthritis. There was perforation of left globe on presentation and the right one was preserved.[springermedizin.de]
Prolonged Immobilization
  • However, since one of the patient's legs was already in a cast from spontaneous Achilles tendon rupture and she had severe rheumatoid lung disease and difficulty ambulating, prolonged immobilization after harvesting periosteum or fascia lata was not considered[healio.com]
Rigor
  • Consequently, rigorous standards must be used to screen donors and process the material. Strict screening of donors to eliminate those with dementing neurological disease is essential.[healio.com]

Workup

  • A systemic workup revealed Wegener's granulomatosis as the cause of this patient's necrotizing scleritis.[webeye.ophth.uiowa.edu]
  • Diagnosis, Workup and Treatment Further investigation into the patient’s ocular history found that he had undergone the I-Brite eye-whitening procedure four years prior to presentation.[reviewofophthalmology.com]
  • Laboratory test As scleritis may occur in association with many systemic diseases, laboratory workup may be extensive.[eyewiki.aao.org]

Treatment

  • Rituximab is a widely used biologic agent, which has shown favourable results in the treatment of vasculitis. But immunosuppressive treatment also bears the risk of severe complications.[ncbi.nlm.nih.gov]
  • Treatment of Scleromalacia Perforans The usual treatment of Scleromalacia Perforans includes the use of both the topical and systemic medications.[webeyeclinic.com]

Prognosis

  • Treatment and prognosis The condition is usually asymptomatic. Rupture of the globe is rare and usually only seen in those with coexisting markedly elevated intraocular pressure, i.e. severe glaucoma 1.[radiopaedia.org]
  • Prognosis and Outcomes Scleromalacia Perforans has a good outcome provided the condition is diagnosed at an early stage and treatment started before any complication arises.[webeyeclinic.com]
  • Paralimbal scleromalacia perforans is reported to have a good prognosis without treatment.! In October 1983 a 33-year-old woman had a one-year history of foreign body sensation and a ten-day history of decreased vision in the right eye.[kundoc.com]
  • Prognosis Gradual reduction of vision is mainly due to progressive astigmatism. American Academy of Ophthalmology. Scleromalacia perforans.[eyewiki.aao.org]
  • Prognosis Prognosis varies depending on the disease classification. It may range from a self-limited episode of inflammation to a severe necrotizing process with vision-threatening complication.[emedicine.medscape.com]

Etiology

  • Etiology Unknown Clinical Presentation Patients with scleromalacia perforans present with deep scleral ulcerations. These scleral ulcerations coalesce, and the thinned sclera shows a bluish color from the underlying uveal tissue.[link.springer.com]

Pathophysiology

  • Pathophysiology Young and Watson suggest three determinants of scleral destruction: activation of scleral fibrocytes and resorption of pericellular matrix, infiltration of the scleral stroma by inflammatory cells, prolonged local vaso-occlusion.[eyewiki.aao.org]
  • Many features of the pathophysiology of the HZO remain obscure. 7 Several mechanisms are thought to play a role on the sclera and may well result in scleral wall weakness.[nature.com]
  • Posterior scleritis is characterized by flattening of the posterior aspect of the globe revealed with imaging, thickening of the posterior coats of the eye (choroid and sclera), and retrobulbar edema. [1] Pathophysiology An autoimmune dysregulation in[emedicine.medscape.com]

Prevention

  • Glaucoma implant surgery using autogenous fascia lata to form a healthy ground and a patch graft to prevent tube erosion seems to be a safe and effective method when normal sclera is lacking, such as in scleromalacia perforans.[ncbi.nlm.nih.gov]
  • Early detection and treatment could prevent vision loss. See an eye care professional right away if you have a sudden change in vision, if everything looks dim, or if you see flashes of light.[icdlist.com]
  • In this case, the patient may have to take drugs to suppress their immune system to prevent rejection of the tissue. Medical treatment of the scleritis once it gets to this point is challenging.[verywell.com]
  • In the CF alone group, we prevented the progress of avascular scleral melting, but there was cosmetic problem due to filling defect.[iovs.arvojournals.org]
