What is it?

The blindbird (Anguis fragilis) is a legless reptile often confused with a snake, when it is actually a lizard. Like all scaly reptiles, it molts regularly, that is to say it sheds the surface layer of its skin to reveal a new one underneath.\n\nDysecdysis refers to abnormal molting: the skin does not come off correctly, remains stuck in patches, or accumulates in several successive layers. This disorder is not an infectious disease per se, but a sign that something is wrong with the animal's living conditions or general health.\n\nIn the blind, poorly performed shedding is of particular concern in the eyes, tail, and extremity of the body, as retained skin there can cause constriction and cut off local blood circulation.

Commonly observed signs

These signs are neither exhaustive nor specific. Only a veterinarian can establish a diagnosis.

Scabs and skin lesions Thickened or darkened skin Constant licking Loss of appetite Reduction Cloudy or opaque eye Non-healing wound

We observe flaps of dry, dull or grayish skin which remain stuck to the body of the animal, sometimes several days after the usual molting period.\n\nCertain areas are more often affected: the tip of the tail, the end of the body, and especially the eyelids (the eyeglasses, these transparent scales which protect the eye, can remain opaque and prevent good vision).\n\nThe animal may rub against objects in the terrarium in an attempt to to tear off the remaining skin, be less active, less voracious, or show localized swelling if a ring of skin squeezes an area of the body too tightly.\n\nIn prolonged cases, the retained skin can progress to a sore, secondary infection, or even loss of the tip of the tail due to lack of blood supply.

When to consult without delay

This list does not replace veterinary advice. It gathers situations that justify a prompt consultation.

Causes and risk factors

The most common cause is insufficient humidity in the terrarium at the time of molting. The skin then dries out too quickly and no longer comes off in one piece.\n\nOther factors may intervene: an unbalanced or poor diet, a state of general dehydration of the animal, an unsuitable temperature, chronic stress, a deficiency in certain nutrients essential to the production of good quality skin, or even an underlying disease which weakens the animal (internal parasites, infection, etc.).\n\nThe absence of rough surfaces (stones, bark) in the terrarium, on which the blind can rub to help the skin peel off, also promotes this disorder.

Blind blinds kept in captivity in a terrarium that is too dry are the most exposed.\n\nAnimals that are old, weakened, recently acquired or stressed by a change in environment often molt less well.\n\nA blind blind that is already sick, parasitized, or at the end of its life is also more likely to exhibit repeated abnormal molts.

Diagnosis and care

Diagnosis is the veterinarian's responsibility, based on clinical examination and laboratory tests. Care is decided case by case.

The exotic animal veterinarian examines the animal for residual skin, particularly around the eyes and tail, and assesses whether constriction threatens blood circulation to an area.\n\nHe also looks for an underlying cause: breeding conditions, hydration status, presence of parasites, general body condition, to understand why the molt went poorly.

Treatment

Management is primarily based on correcting the breeding conditions (humidity, decor).\n\nThe veterinarian can gently remove the retained skin after a prolonged lukewarm bath which softens it, particularly around the eyes and tail.\n\nIn the event of a wound or secondary infection, a local antiseptic treatment or an antibiotic may be prescribed. No forced manipulation should be attempted by the owner without veterinary advice, at the risk of injuring the animal.

Treatment depends on the cause and the animal's condition: it must be determined by a veterinarian. No self-medication.

Prevention

Maintaining an appropriate humidity level in the terrarium, with a clean water point permanently available, greatly limits this problem.\n\nProviding a dedicated humid area (molting box) lined with moss or damp substrate helps the animal to settle there at the time of moulting.\n\nProviding rough decorative elements (flat stones, bark, branches) on which the animal can rub facilitates the natural separation of the skin.\n\nA varied diet adapted to the species, as well as regular monitoring of the animal's general condition, also contribute to good quality moulting.

Possible complications

Skin retained around the tail for too long can lead to necrosis of the tip due to lack of blood circulation, which can lead to loss of the tail.\n\nA persistent opaque eyeglass hinders vision and can lead to eye infection.\n\nFlaps of skin that are not removed can also become a gateway for bacterial or fungal infections of the skin.

When to see a veterinarian

Skin remains stuck to the body for several days after the usual shedding period.\nOne of the eyelids or the telescope remains opaque or cloudy.\nA swelling appears around the tail or other part of the body.\nThe animal rubs insistently or appears embarrassed.\nA sore or area of blackened skin appears on the body.\nThe animal becomes unusually despondent or refuses to feed.

Prognosis

The prognosis is generally good when the problem is identified early and breeding conditions are corrected.\n\nOn the other hand, prolonged untreated constriction in the tail can lead to irreversible tissue loss in this area.

Frequently asked questions

Does a blind girl shed her skin in one piece like a snake?

In a healthy blind blind, under good conditions, the skin usually sheds in one or more large pieces rather easily, much like a snake, unlike many lizards which molt in small fragments.

Should we help the animal to remove its skin?

Never pull forcibly on skin that does not come off easily, as this can injure the animal. A lukewarm bath can help soften the skin; If in doubt, it is best to consult a veterinarian.

Is dysecdysis contagious to other reptiles?

No, it is not a contagious disease. It is a disorder linked to the environment or to the individual state of health of the animal, which is not transmitted to other residents of the terrarium.

How many times a year does a blind girl shed?

The frequency varies according to age, growth and living conditions: growing young molt more often than adults. There is no universal fixed rhythm, but repeated difficult molts should alert.
