Sequelae & Complications of Uveitis

  1. 1. Sequelae and complications of uveitis DR. ANUPAMA KARANTH www.ophthalclass.blogspot.com www.ophthalclass.blogspot.com
  2. 2. Uveitis  Fourth leading cause of blindness in the developed countries  Complications Cataract  Glaucoma  Cystoid macular edema  Hypotony  www.ophthalclass.blogspot.com
  3. 3. Uveitis  Inflammation in the uveal tract  Exudation and cellular infiltration Iris  Ciliary body  Choroid / retina   Consequences Organization of exudates  Fibroblastic activity  www.ophthalclass.blogspot.com
  4. 4. Sequelae  Iris  Ciliary body  Lens  Vitreous  Choroid / Retina www.ophthalclass.blogspot.com
  5. 5. Iris  Organization of exudates Adhesions –Synechiae  Fibrous membranes  www.ophthalclass.blogspot.com
  6. 6. Synechiae  Pupil to lens Posterior synechiae   Peripheral iris to cornea Peripheral anterior synechiae (PAS)   Posterior surface iris to lens capsule Total posterior synechiae  www.ophthalclass.blogspot.com
  7. 7. Synechiae  Pupil to lens  Posterior synechiae www.ophthalclass.blogspot.com
  8. 8. Synechiae  Pupil to lens  Posterior synechiae  Festooned pupil  360 degrees of posterior synechiae – seclusio pupillae /ring or annular synechiae www.ophthalclass.blogspot.com
  9. 9. Synechiae  Peripheral iris to cornea  Peripheral anterior synechiae (PAS) www.ophthalclass.blogspot.com
  10. 10. Synechiae  Peripheral iris to cornea  Peripheral anterior synechiae (PAS) www.ophthalclass.blogspot.com
  11. 11. Synechiae  Posterior surface iris to lens capsule  Total posterior synechiae www.ophthalclass.blogspot.com
  12. 12. Posterior synechiae Entire pupil Posterior Seclusio border to lens synechiae pupillae (360deg) Peripheral iris pushed to Iris bombé Pupil block cornea Secondary angle closure glaucoma Iris bombé: ballooning of iris, shallow anterior chamber www.ophthalclass.blogspot.com
  13. 13. Iris bombé Iris bombé: ballooning of iris, shallow anterior chamber www.ophthalclass.blogspot.com
  14. 14. Peripheral anterior synechiae Peripheral Closure of anterior trabecular synechiae meshwork Secondary Block to angle aqueous closure drainage Gonioscopy to visualize angle in every case of uveitis www.ophthalclass.blogspot.com
  15. 15. Sequelae…  Extensive exudation in iris and ciliary body  ‘Plastic’ iridocyclitis  Organizes into membranes Pupil  Retrolental space  www.ophthalclass.blogspot.com
  16. 16. Fibrous membranes  Pupil  Occlusio pupillae  Pupil block  Secondary angle closure glaucoma www.ophthalclass.blogspot.com
  17. 17. Fibrous membranes  Retrolental space Cyclitic membrane  Posterior lens, vitreous base and pars plicata  Hypotony  Retinal detachment  Ciliary body atrophy and shrunken eye  www.ophthalclass.blogspot.com
  18. 18. Pupil in iridocylitis  Miotic  Posterior synechiae  Festooned pupil  Seclusio pupillae  Occlusio pupillae  Ectropion uveae www.ophthalclass.blogspot.com
  19. 19. Ectropion uveae www.ophthalclass.blogspot.com
  20. 20. Lens  Iris pigments on lens surface  Posterior subcapsular cataract Inflammation and corticosteroid use  Complicated cataract  Breadcrumb appearance  Polychromatic lustre  www.ophthalclass.blogspot.com
  21. 21. Lens pigments and cataract www.ophthalclass.blogspot.com
  22. 22. Vitreous in uveitis  Exudates get organized  Vitreous membranes, contraction  Traction on retina Tractional retinal detachment  Retinal tears and rhegmatogenous retinal detachment  www.ophthalclass.blogspot.com
  23. 23. Choroid and retina  Destruction of retinal pigment epithelium (RPE) and Bruch’s membrane Chorioretinal atrophic patch  White of sclera seen through   Fibroblastic activity Chorioretinal adhesion  RPE proliferation at edges – pigmented scars  Choroidal neovascular membranes   Permanent scotomas www.ophthalclass.blogspot.com
  24. 24. Complications Cataract  Glaucoma  Hypotony  Cystoid macular edema  www.ophthalclass.blogspot.com
  25. 25. Causes of glaucoma  Closed angle Posterior synechiae  Peripheral anterior synechiae   Open angle Cells and protein blockage of trabecular meshwork  Trabeculitis  Corticosteroid induced  www.ophthalclass.blogspot.com
  26. 26. Causes of hypotony  Acute inflammation of ciliary body - temporary hyposecretion  Chronic ciliary body damage – permanent hypotony  Ciliary body traction from a cyclitic membrane Hypotony more dangerous in chronic uveitis than glaucoma www.ophthalclass.blogspot.com
  27. 27. Hypotony – phthisis bulbi (LE) www.ophthalclass.blogspot.com
  28. 28. Cystoid macular edema  Inflammatory mediators reach the macula  Common cause of visual loss in uveitis www.ophthalclass.blogspot.com
  29. 29. End stage of inflammatory eye diseases  Atrophy with shrinkage Small globe  Structures still recognizable  ATROPHIC BULBI  Eg. Chronic long standing uveitis   Atrophy with shrinkage and disorganization Small globe  Structures unrecognizable  PHTHISIS BULBI  Eg. Purulent endophthalmitis  Irreversible blindness www.ophthalclass.blogspot.com
  30. 30. Phthisis bulbi  Clinically, any globe which is Sightless  Shrunken  Shapeless (‘squared-off’)  Soft   Associations Dystrophic calcification eg. band keratopathy  Intraocular ossification  Risk of intraocular malignancy  www.ophthalclass.blogspot.com
