Subconjunctival Hemorrhage (Red Eye) : Causes,Diagnosis,Treatment,Management

10

Labels:




What is Subconjunctival Hemorrhage ? 
The name says it all : simply put its bleeding ( or collection of blood ) below the conjunctiva.


What is "Conjunctiva" ?
Its the thin,transparent,moist membrane which is the outermost covering of the eye.Its blood vessels are very fragile and thus can easily rupture.

What does the patient complain of ? ( SYMPTOMS )
  • Red Eye ( blood collects between the conjunctiva and the white of the eye - sclera )
  • may be assosciated with itchy eyes
  • Usually asymptomatic
What the doctor should observe ? ( SIGNS )
Blood underneath the conjunctiva,often in one sector of the eye.
Sometimes the entire view of the white of the eye (sclera) can be obstructed by blood.

What Causes Subconjunctival hemmorhage ?
  • Trauma : most common cause
  • coughing,sneezing,constipation,epileptic fits,strangulation : these cause sudden venous congestion of the head leading to subconjunctival hemorhage
  • inflammation of the conjunctiva : which may be caused by bacterial or viral infections
  • Hypertension
  • Blood dyscrasias : like anemias , luekaemias
  • Bleeding disorders : like hemophilia
  • Antiplatelet or anticoagulant medications : like aspirin,clopidogrel,warfarin
  • in some cases,the cause is unknown
" But doc, my eye looks really scary " !!!
Yeah , sure it does...but rest assured..,its usually a harmless condition.

    Subconjunctival hemorrhage in the process of healing ( being absorbed )
              
What is the treatment for subconjunctival hemorrhage ?
  • there is no specific treatment,the accumulated blood slowly gets reabsorbed in 7-21 days. ( so now u can guess how "scary" red eye really is )
  • Reassuring the patient forms the most important part of the treatment. 
DONT's :  - use medications like aspirin,clopidogrel as these may aggravate bleeding ( if you do use them for  other medical ailments then do consult with your healthcare specialist )
            - since the eyes may be itchy,artificial tears may be prescribed but some argue it may delay or interfere with the natural healing process.
Do's :   - if a specific underlying cause is discovered then it must be treated.
           - in case of assosciated infection of the conjunctiva , antibiotic eye drops are prescribed.

Notes for the Doc - Remember to : 

  1. Ask for history of  eye rubbing,trauma,severe cough,medications used,bleeding or clotting disorders.
  2. Ask whether this has frequently happened before.
  3. And plz do check the Blood pressure !!

Lacrimal Syringing - How and why its done

Labels:



What Is Lacrimal Syringing ?

It is a common procedure performed by an ophthalmologist ( or an ENT surgeon ) wherein fluid (normal saline ) is passed from one end of the tear drainage system ( lacrimal apparatus ) to see whether it emerges from the other end. Thus we can easily asses whether the tear drainage system is patent or blocked.

Why Is Lacrimal Syringing Done ?
When a patient complains of  excessive watering of the eyes , the doctor has to check whether his/her tears are draining properly..ie whether the watering eyes are due to a block in the tear drainage system.

  1. To check the tear drainage system (naso lacrimal duct ) for any blockage ( the site and nature of the block ).
  2. To flush out debris from the tear drainage system ( eg due to any infection ) .
  3. In India it is done before cataract surgery to rule out chronic dacryocystitis ( infection of the nasolacrimal sac ) .
  4. To instill antibiotics in the tear drainage system and also dye for X rays.
