“…In severe cases, the abnormal hair growth can lead to corneal lesions such as ulceration and keratitis [ 1 , 12 , 13 ]. There are several different treatment methods, but recurrence and complications are associated with all procedures [ 3 , 13 – 15 ]. Therefore, a reduction of the incidence by selective breeding would be advantageous.…”

Background Distichiasis is the most frequently recorded eye disorder in the Norwegian Staffordshire bull terrier (SBT). The condition is often mild but can, in severe cases, lead to pain and blindness. The current study's main purpose was to estimate the heritability based on pedigree information as well as single nucleotide polymorphisms (SNPs) to evaluate whether it is realistic to reduce the frequency by systematic breeding. The majority of the dogs had only one examination as a young puppy. To evaluate whether this early screening gave a reliable representation of the disease burden in the population, we compared the diagnosis in puppies and adult dogs. Results Our material consisted of data from 4177 dogs with an overall prevalence of distichiasis of 8.38% (CI 7.56–9.26). The prevalence in puppies examined around eight weeks of age was significantly lower than in dogs examined after 52 weeks (2.87%, CI 2.29–3.54 versus 18.72%, CI 16.71–20.87). The heritability was estimated in dogs examined after 52 weeks. We used both pedigree (1391 dogs) and genotype (498 dogs) information for the estimates. The pedigree-based heritability was ~ 0.22 (on the underlying scale ~ 0.48), while the genomic-based heritability (on the underlying scale) was ~ 0.47, and ~ 0.37 when excluding close relatives with equal affection status. Conclusions Screening for distichiasis in puppies before eight weeks of age is not sufficient to give an accurate estimate of the prevalence, and an additional examination after one year is recommended. The heritability of distichiasis is medium to high, showing that it should be possible to reduce the prevalence by selective breeding.

“…Regrowth of distichiae after cryotherapy treatment in dogs was not observed during a 6 months of follow‐up 11 . Furthermore, transconjunctival thermal electrocautery technique was successful in 96% of dogs 12 . Postsurgical complication of these techniques such as scarring, hypopigmentation, cicatricial entropion, and qualitative tear film deficiency highlights the importance in finding an alternative effective surgical treatment to correct distichiasis in animals.…”

“…Unlike simple manual epilation, permanent corrective surgery aims to redirect hair away from the ocular surface or destroy the hair follicle, thus decreasing the risk of possible regrowth 1,2 . Surgical treatment options reported in veterinary medicine include: electrolysis, electrocautery, cryotherapy, conjunctival resection, splitting eyelid with tarsoconjunctival resection, CO 2 laser, partial tarsal plate excision, and Celsus–Hotz technique 8‐13 . In addition to recurrence, scarring, eyelid distortion, cicatricial entropion, eyelid depigmentation, and qualitative tear film deficiency had been described as postoperative complications of these surgical distichiasis techniques 1,8‐13 …”

Objectives To describe the use of direct‐contact diode laser as a new treatment for distichiasis. Study design Case report. Animals A 2‐month‐old Italian Friesian calf with bilateral excessive tearing and corneal opacification was presented to the Visionvet Eye Clinic. Abnormalities on ophthalmic examination included epiphora, seromucous discharge, bilateral distichiasis and secondary chronic keratitis affecting both eyes. Methods Distichiae were surgically removed after insertion of the 810‐nm diode laser tip into the associated meibomian gland. Results Clinical signs gradually improved postoperatively with minimal and transient post‐operative complications. Ophthalmic examination was within normal limits 6 months later beyond distichiae. Conclusion Treatment of distichiasis with direct‐contact 810‐nm diode laser resulted in long‐term resolution of signs in the case described here.

“…Nonsurgical methods include electrolysis, cryotherapy, and transconjunctival thermal electrocautery. [ 16 18 ] The use of blend electrolysis (2–3 mA for 15–30 s) in 78 canines showed recurrence in 65% of eyes, lid margin scarring in 33% of eyes, and depigmentation in 27% of eyes. [ 17 ] Transconjunctival thermal electrocautery in 88 canine eyelids was successful in 69% of cases, with recurrence in 25% and emergence of new distichiatic eyelashes in 6% of eyelids.…”

“…The average time taken for eyelashes to regrow after electrolysis varies from 11 to 192 days. [ 18 ] Surgical techniques described include partial tarsal plate excision, wedge resection, and palpebral conjunctival resection. [ 19 ] Excision of a 2–3-mm wide tarsoconjunctival plate 2 mm away from the lid margin produced better success rates than electrolysis.…”

Distichiasis, an extra row of eyelashes emerging from meibomian gland orifices, occurs due to the metaplastic transition of sebaceous glands into the pilosebaceous unit. It can present congenitally, such as in lymphedema distichiasis syndrome, or secondary to acquired conditions, such as cicatrizing conjunctivitis, trachoma. This review summarizes the etiology of distichiasis, its presentation, the evolution of various surgical techniques, and their outcomes in human and animal eyes. The published literature has focused on the different treatment modalities and their outcomes; the etiopathogenesis of this condition remains elusive. Truncating mutations (missense, frameshift, and nonsense) in the Forkhead family gene FOXC2 are involved in the distichiasis–lymphedema syndrome. The treatment options are no different for congenital versus acquired distichiasis, with no specific available algorithms. Acquired distichiasis in cicatrizing ocular surface diseases is difficult to manage, and existing treatment options offer success rates of 50%–60%. The outcomes of electroepilation or direct cryotherapy are not as good as surgical excision of distichiatic lashes after splitting the anterior and posterior lamella under direct visualization. The marginal tarsectomy with or without free tarsoconjunctival graft has shown good results in eyes with congenital and acquired distichiasis. The details of differences between normal and distichiatic lash, depth, or course of distichiatic eyelashes remain largely unknown. Studies exploring the distichiatic eyelash depth might improve the outcomes of blind procedures such as cryotherapy or radiofrequency-assisted epilation.
