 Surgical remedies are : — 



Expression, perhaps the most popular. Use Knapp's roller 

 forceps for squeezing out the granulations. Wash after- 

 wards with mercury bichloride. General anaesthesia is 

 usually required. 



Native Chinese operation for lower-lid entropion, pinching the skin between two small 

 sticks. In this case the compression was not complete and two curious tumours 

 resulted. (By Jeffreys.) 



Grattage, which consists of scrubbing the granulations with a 

 stiff tooth brush, followed by an eye wash of mercury bi- 

 chloride with or without previous scarification. 



Excision, to remove the conjunctival fold containing the 

 granules. The conjunctiva is often injured in this process. 



Curetting is popular with some surgeons.
