Eye testing is mandatory for all TDR breeders in the USA.   In all other countries however this is recommended, but optional. The Tamaskan has had one suspected case of juvenile cataracts, but vet reports were never submitted to the TDR to confirm the condition. However the diseases listed below affect the majority of breeds behind the Tamaskan Dog and so preparing yourself by having your dogs tested is important.

Juvenile Cataracts:  A cataract is an opacity in the lens, which if extensive enough, can cause visual problems or complete blindness. The cataract occupies a particular part in the lens so that it can be recognised as being of an inherited type.  Vision loss to the point of blindness can occur in either one or both eyes.  The onset can occur as early as 4 months of age with higher incidence reported between 6 and 18 months old.

Glaucoma:  All arctic circle breeds are predisposed to glaucoma.  It is thought to be inherited but the mode is unknown.  Glaucoma is caused by impairment of the flow of aqueous humor which causes the pressure in the eye to increase.  Although present at any age, the disorder is mostly seen in middle aged dogs.  A cloudy or red eye may be noticed which may be painful.  Treatment is surgical and or medical.

Corneal Dystrophy: The term Corneal Dystrophy is used to describe a variety of disorders affecting the layers of the cornea (the clear surface of the eye).  Cloudiness is the primary characteristic of corneal dystrophy that you are likely to notice.  Once Corneal dystrophy occurs, the cloudy areas will not go away.  Vision is usually not affected by small areas of corneal dystrophy but larger cloudy areas can sometimes interfere with normal vision. Siberian Huskies have a form of corneal dystrophy which is properly called "crystalloid corneal dystrophy". It is inherited as a recessive trait. This form of dystrophy usually begins between 5 and 27 months of age.

Progressive Retinal Atrophy (PRA): This disorder affects the retina, the light sensitive inner lining of the posterior part of the eyeball. The Siberian Husky has a unique type of PRA that is only found in Siberians and man.  This type of PRA is called "X" Linked PRA, since it is transmitted through the "XX" chromosome of the female. It will cause a loss of night vision followed by a loss of day vision, eventually blindness.  The disease in males can be devastating with loss of vision as early as 5 months of age.

Entropion:  An entropion eyelid occurs when the eyelid rolls over against the eyeball and the eyelashes rub against the surface of the eye. The rubbing action irritates the cornea and may result in corneal ulcers. This condition is treated surgically.
