Lacrimal sac syringing

  1. 1. By. Chittranjan kumar Enternship
  2. 2. Def of lacrimal Apparatus It is physiological system has formation and drainage also give nurshiment to cornea with help of tear HENCE Any occlusion or defect in lacrimal drainage detected to a investigation is called lacrimal syringing. Syringing is the method to test the structural integrity of lacrimal drainage system .
  3. 3. ANATOMY OF THE LACRIMAL DRAINAGE SYSTEM  Puncta One punctum is present at the medial end of both the superior and inferior lid.  Vertical canaliculus This is about 2mm long and joins the horizontal canaliculus at a right angle called the ampulla.
  4. 4.  Horizontal canaliculus This is about 8mm long and usually joins its fellow to form the common canaliculus  (Naso)lacrimal sac This is about lOmm long and funnels into the nasolacrimal duct.  Nasolacrimal duct This is about l2mm long and opens into the inferior nasal meatus The Valve of Hasner closes the
  5. 5.  Most common blockage is at junction of sac and NLD near valve of haustner .  Syringing should be done with lower canaliculus .
  6. 6. PHYSIOLOGY OF THE LACRIMAL DRAINAGE SYSTEM Pre –blink :- Tear spread on the globe Like Tear Meniscus During blink:- On blinking, the attachment of the preseptal orbicularis muscle helps create positive and negative pressure. Due to pressure in the lacrimal sac which sucks the tears. This is called the tear pump. Post-blink:- Gravity then helps keep the sac empty.
  7. 7. PHYSIOLOGY OF THE LACRIMAL DRAINAGE SYSTEM Pre Blink Tear spread on the Globe During Blink Post Blink Like tear Meniscus Lacrimal sac suck the tear Empty the lacrimal Sac Tear meniscus Known as Tear pump
  8. 8. Lacrimal punctum Dialatation Vertically Dialatation Horizontally Dialatation
  9. 9. Lacrimal syringing
  10. 10. No Regurgitation Regurgitation with pus other punctum Regurgitation other punctum clear without delay Regurgitation same punctum Passage patent Sac NLD junction block Common canaliculus block Same canali block Interpretation
  11. 11. EQUIPMENT REQUIRED  Lacrimal punctum dilator  lacrimal cannulae  3 or 5m1 disposable sterile syringes  Anaesthetic drops, e.g. 4% xylocaine  cotton  Normal saline/ Ringer lacted  antibiotic solution  pt Better to supine position
  12. 12. Importance of syringing  One of the most important prior to intra ocular surgery .  If syringing is abnormal first the surgery of lacrimal sac is required before cataract surgery otherwise infection can reach intra ocular causing . Endopthalmitis
  13. 13. Diseases of lacrimal sac  Dacryocystitis Inflammation of Lacrimal sac is not uncommon condition may occur in two form - Congenital Dacrycystitis Occurs in new born infant. - Adult Dacrycystitis
  14. 14. Surgery of Lacrimal sac Dacryocystorhinostomy(DCR) Re stablishes the lacrimal drainage. Dacryostectomy (DCT) Removal of lacrimal sac.
