Primary lens luxation " "(PLL) ""for breed see info

Primary lens luxation (PLL)


The zonula fibres secure the position of the lens. Dogs affected from PLL have painful glaucomas and blindness due to a dislocation of the lens due to a breakdown or disintegration of the zonula fibres. PLL can be inherited or acquired. Therefore the disease might also affect genetically free dogs. First clinical signs of the inherited form of PLL are detectable at the very young age of 20 months. A complete lens luxation typically occurs at the age of 3 to 8 years.

Trait of inheritance

In most cases heterozygous carriers are healthy. However, it is estimated that about 2 – 20 % of the carriers will develop PLL.

Test duration

3-5 days after arrival of the sample in the lab


The DNA test is performed out of EDTA blood or buccal swabs. Required swabs can be ordered free of charge. (Buccal swab order-form). If a swab is sent in, possibly the genetic material is not sufficient to run the test. In this case it would be best to send in an EDTA blood sample.

Testing procedure

Please send in your sample together with the lab order genetic. Results will be transmitted optionally via post, fax or email. After completion of the test you will receive a separate invoice. Payment can be made via credit card or bank transfer.
Breeding club discounts apply if a copy of the membership card is sent together with the respective samples. Due to administrative reasons the invoiced price can not be altered subsequently.
