Glassblower's Cataract

Cataract Glass Blower's


Presentation

  • Initially, a cataract presents discretely and may even go unnoticed, but the visual impairment worsens as the cataract grows larger.[amboss.com]
  • […] prematurity e. toxocariasis (nematode infection) f. posterior uveitis Congenital Cataract Important Facts 33% Idiopathic- unilateral or bilateral 33% inherited- bilateral 33% % associated with systemic disease- usually bilateral Other ocular anomalies present[quizlet.com]
  • Both conditions present unique challenges for cataract surgery. Pseudoexfoliation syndrome refers to a condition that involves the entire body, but manifests primarily in the eye.[brightfocus.org]
  • This substance is probably closely associated with various anterior segment tissues, including trabecular meshwork and corneal endothelium, iris stroma and vessels, and lens epithelium. 3 CLINICAL PRESENTATION Exfoliation syndrome is often subtle and[glaucomatoday.com]
  • If you do not include enough of these antioxidants in your diet, they will not be present in your eyes to offer you protection from oxidative damage.[liverdoctor.com]
Weakness
  • Possible capsular weakness B. Can be more difficult to secure the IOL VI. Describe appropriate patient instructions A. Avoid exposure to intense infrared radiation and heat B.[p2.aao.org]
  • Very advanced cataracts with weak zonules are liable to dislocation anteriorly or posteriorly.[sosm.my]
  • When these structures become weak, the lens can come forward and cause the angle to narrow. Therefore, it is sometimes recommended that a preventive laser iridotomy be performed in order to prevent an acute angle closure attack.[brightfocus.org]
  • Suggested mechanisms include anterior movement of the lens from zonular weakness as well as the formation of posterior synechiae due to increased iris adhesion to the lens from exfoliative material. 3 Iridotomy or lens extraction may be indicated to protect[glaucomatoday.com]
Aspiration
  • […] terms standard extracapsular or planned extracapsular refer to an operation in which the lens nucleus is delivered intact through a limbal incision of about 10 mm, in contrast to phacoemulsification, in which the nucleus is ultrasonically fragmented and aspirated[books.google.com]
  • Irrigation and Aspiration – The cortex which is the soft outer layer of the cataract is aspirated or sucked away.[legazpieye.com]
Vascular Disease
  • Master the latest advances in ophthalmology: radical changes in the management of macular disease, including the widespread introduction of VEGF inhibitor therapy; recent developments in the investigation and treatment of retinal vascular disease; new[books.google.de]
Contusion
  • : anterior rosette-shaped clouding of the lens ( contusion cataract ) In perforated lens injuries: posterior rosette-shaped clouding of the lens Special features in congenital cataract Congenital cataracts usually present with different symptoms than[amboss.com]
Progressive Loss of Vision
  • Subjective - progressive loss of vision; objective lens opacity, in the early stages ogranichivayutsya back with his pole, later spreading over the whole lens. For a long, very slow, without any phenomena of irritation.[lecheniebolezni.com]
Strabismus
  • […] associations a. cataract (15%)- unilateral or bilateral, pearly nuclear or diffuse (may be present at birth or develop several weeks or months later) b. also: microphthalmos, glaucoma, anterior uveitis, iris atrophy, retinopathy, pendular nystagmus, strabismus[quizlet.com]
Suggestibility
  • Studies suggest that approximately 40% of patients who have exfoliation syndrome will develop glaucoma. 3 It is debatable whether unilateral or bilateral disease is more common, but the condition most often presents in an asymmetric manner. 3 PATHOGENESIS[glaucomatoday.com]
  • Epidemiological studies suggest a dose-dependent association between short wavelength UVR and cortical cataract.[nature.com]
  • A narrow anterior chamber, and/or a hazy, ‘steamy’ cornea with perilimbal injection suggests angle closure glaucoma.[oogziekenhuis.me]

Treatment

  • Treatment GLASSBLOWERS CATARACT (CATARACTA PROFESSIONALIS) In fresh cases the cure is facilitated by the elimination of the action of radiant energy; in advanced cases surgical treatment is required. source[lecheniebolezni.com]

Prognosis

  • Describe the natural history, outcome and prognosis 1. Progression of lens opacities 2. Decrease in vision from affected eye B. Describe medical therapy options 1. No significant medical therapy exists C. Describe surgical therapy options 1.[p2.aao.org]
  • What is the prognosis of cataracts? The rate of progression of cataracts is usually predictable and surgery is successful in restoring vision in a large majority of cases.[medicinenet.com]

Etiology

  • Etiology Clouding of the lens may be congenital or acquired.[amboss.com]
  • As in the headline, the dispute between Alfred Vogt and Hans Goldmann occupied minds in the middle of the last century, as they tussled over the etiology of “glassblowers’ cataract.”[healio.com]

Prevention

  • This condition may be prevented by wearing protective glasses while practicing these occupations. Glassblowers tend to work with very high-temperature objects and equipment, which emit a great deal of infrared radiation through black-body radiation.[en.wikipedia.org]
  • Prevention CATARACT GLASSBLOWERS (CATARACTA PROFESSIONALIS) Mechanization of the work of glassblowers, workers wearing protective glasses and most importantly the shift in the process of making glass (replacement of open-air baths, closed furnaces in[lecheniebolezni.com]

  • Fruits and vegetables are full of antioxidants, which in theory could prevent damage to your eye's lens. Studies haven't proven that antioxidants in pill form can prevent cataracts.[snezha.com]
