Enti'opioii. Turnhig in of the Eyelid. 345 



mation affecting the edge of the Hd and the follicle, and the 

 offending hair is not only badly directed but small and shrunken 

 as well. On this account it is not always easy to recognize it, 

 and accordingly in cases of conjunctivitis without apparent cause 

 it is well to examine carefully with the aid of oblique focal 

 illumination. 



Treat))ient consists in pulling out the offending hair with ciliary 

 forceps, avoiding bending it lest it break off short and become at 

 once more irritating and more difficult of extraction. In case 

 the hair grows anew in the same direction extract it anew and 

 destroy its root with the electric cautery. 



ENTROPION. TURNING IN OF THE EYELID. 



In foals, puppies, hounds, with narrow fissure, and conjunctivitis, or 

 tarsitis. Permanent bandaging, orbicularis spasm. Symptoms : disappear- 

 ance of tarsus and lashes by involution. Treatment : in spasm fix by plas- 

 ter ; suture skin : excise elliptical section of skin and suture edges together. 

 Release cicatrices. 



Inversion of the eyelid or a portion of it, with consequent 

 trichiasis, conjunctivitis and lachrymation has been met with con- 

 genitally in foals ( Aubry, Bourdeau, Hamon) and puppies 

 (Cadiot, Almy). Hounds have especially suffered. In the older 

 animals it is largely determined by abnormally narrow fissure, 

 and by old .standing disease of the conjunctiva or tarsus, with 

 cicatricial contraction or adhesion. Persi.stent bandaging turns 

 in the cilia and contributes to entropion. Finally a persistent 

 .spasm of the ori^icularis muscle may bring it about. 



Symptoms Trichiasis is irsually, though not always, present. 



In any case the tarsus is turned inward so as to press upon the 

 front of the bulb, or even to disappear completely. Thickening 

 and distortion of the lid is a not infreqitent condition. 



Treatment. In case of simple spasm clip or shave the hairs 

 from the lid corresponding to the lesion, and clo.se to the tarsus 

 attach a strip of plaster. When firmly adherent draw it sufB- 

 ciently to efface the entropion and attach it to the .skin of the 

 face.
