Intumescent Cataract

Intumescence of Crystalline Lens


Presentation

  • A slit-lamp examination of those eyes clearly indicated that the lenses were present behind the iris but that they were swollen and opaque (intumescent cataract).[ncbi.nlm.nih.gov]
  • Nine cases are presented, six of them in detail, which suggest that there is a high risk of bullous keratopathy developing when the lens is removed for the treatment of acute glaucoma due to an intumescent cataract.[ncbi.nlm.nih.gov]
  • To present the clinical and histologic findings of a patient in whom intumescent cataract developed after successful topical mitomycin-C (MMC) chemotherapy for conjunctival melanoma originating from primary acquired conjunctival melanosis (PAM) with atypia[ncbi.nlm.nih.gov]
  • Many of the lenses have a considerable amount of non-cataractous lens structure present at the time of surgery.[webeye.ophth.uiowa.edu]
  • Two of these had presentation of vitreous in the anterior chamber during the operation and the slit lamp examination showed vitreous bands adhering to the corneoscleral wound at the time of followup.[ijo.in]
Swelling
  • Imbibe Aqueous Through Semipermeable Lens Capsule Lens Swells 1) UNANTICIPATED ELEVATED ENDOCAPSULAR PRESSURE ENDOCAPSULAR PRESSURE 2) COMPROMISED VISUALISATION OF THE CAPSULORHEXIS THE CAPSULORHEXIS TWO DIFFICULTIES HydroStatic Or Intra Lenticular Pressure[slideplayer.com]
  • Not only has the crystalline lens swelled and softened—triggering liquefaction that leads to leakage of lens proteins—but the swollen contents of the capsular bag increase the intralenticular pressure and induce stretching of the lens capsule.[crstodayeurope.com]
  • This stage is also known as the intumescent or swelling stage because the lens swells up a little and tends to shallow or decrease the anterior chamber (the liquid space between the back of the clear cornea and the front of the lens and iris).[healthguidance.org]

Nightmare
  • Cataracts left to progress to a hypermature state are a potential nightmare for the cataract surgeon if the necessary precautions are not taken.[crstodayeurope.com]
Suggestibility
  • Nine cases are presented, six of them in detail, which suggest that there is a high risk of bullous keratopathy developing when the lens is removed for the treatment of acute glaucoma due to an intumescent cataract.[ncbi.nlm.nih.gov]
  • I suggest painting the capsule underneath the protection of an OVD. Without trypan blue, capsulorrhexis formation may be tricky, as there is a risk for the rhexis to extend to the perimeter.[crstodayeurope.com]
  • Duke Elder [3] also states that more recently it has been suggested that it is safer to do an iridectomy in order to relieve pupillary block and then to treat any residual raised tension by medical means.[ijo.in]
  • A pure-black pupil due to cataract suggested a nuclear cataract. In India, the cataracta nigra was occasionally seen.[webeye.ophth.uiowa.edu]
  • For this purpose, Gimbel and Willerscheidt originally suggested the two-stage CCC approach with a small capsulorhexis or a multipuncture of the anterior capsule before capsulotomy (7).[scielo.br]

Treatment

  • Nine cases are presented, six of them in detail, which suggest that there is a high risk of bullous keratopathy developing when the lens is removed for the treatment of acute glaucoma due to an intumescent cataract.[ncbi.nlm.nih.gov]
  • The accepted treatment of such cases, if brought under treatment early before peripheral anterior synechiae develop, is the same as for primary acute closed angle glaucoma.[ijo.in]

Pathophysiology

  • Pathophysiology In an eye with advanced cataract formation, the lens is swollen or intumescent. Progressive reduction occurs in the iridocorneal angle.[emedicine.medscape.com]
  • Diabetes or elevated blood sugar Steroid use (oral, IV, or inhaled) Ultraviolet exposure Smoking Ocular diseases: Retinitis Pigmentosa, Uveitis Ocular Trauma Prior ocular surgery Procedures: Vitrectomy, Intravitreal injections Genetic predisposition Age Pathophysiology[eyewiki.org]

Prevention

  • The use of a single central disruptive pulse of energy may maintain an equal distribution of vector forces, preventing uncontrolled splitting of the anterior capsule to the periphery.[scielo.br]
