The most common ocular problem of snakes is retained spectacles and is usually associated with [[Snake Dysecdysis|dysecdysis]]. Temporary blindness can result from the serial retention of spectacles and permanent blindness may result from a subsequent secondary infection.

The most common ocular problem of snakes is retained [[Spectacle|spectacles]] and is usually associated with [[Snake Dysecdysis|dysecdysis]]. Temporary blindness can result from the serial retention of spectacles and permanent blindness may result from a subsequent secondary infection.

Disease of the [[Spectacle|spectacle]] needs to be differentiated from the normal changes that occur prior to [[Ecdysis|ecdysis]]. Here the spectacle becomes opaque then clear immediately prior to shedding. Retained spectacles result in a raised hardened mass over the spectacle.

==Therapy==

==Therapy==

The cornea underlying the [[Spectacle|spectacle]] is very delicate and attempts to wrench off the retained spectacle with forceps have a high success rate of damaging the cornea. Prior to any attempts at removing the spectacle the snake should be kept in a high humidity environment for a minimum of 24 hours. During this time artificial tears should be applied several times. This may soften the retained spectacle and allow their removal. Soaking prior to manipulation may further soften the [[Spectacle|spectacles]]. The next step is using a moistened cotton-tipped applicator to gently rub from the lateral edges of the retained spectacle inwards. In the majority of cases it will be [[Ecdysis|shed]]. If not the procedure of softening can be repeated. In some cases it is necessary to wait until the next [[Ecdysis|shed]].

Prevention of retained spectacles is related to general skin health. Poor husbandry, especially low humidity, leads to [[Snake Dysecdysis|dysecdysis]].

The treatment of retained spectacles should be specifically aimed at relieving the ocular problem but also directed towards any dysecdysis.  The principles of treatment for [[Snake Dysecdysis|dysecdysis]] are the same whether or not retained spectacles are present.
