		+	==Introduction==
		+	[[Image:Cataract donkey.jpg\|right\|thumb\|250px\|<small><center>Complete visual impairment from advanced cataract
		+	with continual miosis. (Image courtesy of [http://drupal.thedonkeysanctuary.org.uk The Donkey Sanctuary])</center></small>]]
		+	A high proportion of [http://drupal.thedonkeysanctuary.org.uk The Donkey Sanctuary’s] herd is elderly and so acquired, diffuse cataracts are very common. These are easily diagnosed.
		+
		+	==Clinical Signs==
		+
		+	* The '''lens is obviously opaque''' and the '''pupil fully dilated in severe cases'''
		+	* There is '''reduced vision''', especially in dim light
		+	* '''Lack of a pupillary light response''' (PLR) indicates an advanced condition
		+	* They can be unilateral or bilateral
		+
		+	==Diagnosis==
		+
		+	'''Pupillary dilation''' should be achieved prior to ophthalmoscopy to check the extent of the cataract, to rule out [[Lens Luxation - Donkey\|lens luxation]] and to check the fundus for [[Uveitis - Donkey\|recurrent uveitis]], which will eventually cause cataracts. As most cases are secondary to [[Uveitis - Donkey\|recurrent uveitis]], '''posterior synechiae''' develop due to the inflammatory response.
		+
		+	<u>'''Nuclear sclerosis'''</u> can be mistaken for cataracts. This is a normal ageing response as the lens hardens and takes on a
		+	‘pearl-like’ appearance. However, the fundus is still visible through this.
		+
		+	==Treatment==
		+
		+	'''Surgery'''' to remove the lens is useful in cases of''' congenital cataracts'''. The optimal age for surgery is during the first few months. If [[Uveitis - Donkey\|recurrent uveitis]] has occurred then the success rates are lower.
