Film on Dog’s Eyes – How to Overcome this Symptom?


The state of your pet’s health is always literally “written” in its eyes. If the eyes are lively, shiny, with pure whites and an open look – there is nothing to worry about. Opacity and formation of a film on the dog’s eyes indicate high probability of a leukoma.Its causes are various – from diseases of the visual organ to accidental injury, but nonetheless the condition requires urgent medical attention.

Aspect of the Disease

A walleye or in medical terminology ‘leukoma’ gradually covers parts of the optic organ (retina, pupil, corneal epithelium) with a whitish veil (film). The condition leads to full or partial loss of vision up to absolute blindness. The on dog's eyes filmlocation of the cloudy spot is classified into three types:

  1. Total – the eye is completely covered with a muddy film.
  2. Central – the film covers the pupil or a part of it.
  3. Peripheral – leukoma’ affects the whites and some part of the irises.

If a dog has a white film covering its eyes according to the total or central type – nothing can be done, there is next to no chance of retaining seeing. At least, animal medicine does not know a single case where a dog could be cured from such a pathology.


Muddy whitish spot on the eye is the main sign of the film formation. Some factors, however, may precede its appearance or accompany it:

  • white film on dog’s eyesOne / two eyes watering intensely.
  • Purulent discharge
  • Photophobia (the pet hides its eyes from bright light).
  • Deformation of the corneal tissue structure.
  • Partial / whole optic opacity.
  • The white spots are ‘bulging’ out.

The manifestation of the very first pathological symptoms requires prompt medical attention and special preventive treatment.


White film on dog’s eyes does not appear independently. There is always some cause triggering the formation mechanism. Scientists identify several most common ones:

  1. white film on dog’s eyePannus is a disease of an autoimmune nature, in which the ocular epithelium is perceived as foreign cells and is replaced by scar tissue, gradually forming into an opaque ‘curtain’.
  2. Diseases of viral, bacterial or fungal origin (keratitis, common or adenoviral conjunctivitis, blepharitis, cryptococcosis, etc.).
  3. Erosive or ulcerative formations on the surface of the eye as a result of mechanical damage or infectious complications.
  4. Injuries (wounds, burns, etc.).
  5. Irreversible degenerative processes specific to aging (cataracts, nuclear sclerosis).
  6. Complications after surgery on the eyeball (removal of formations, etc.).
  7. Tumors of various origins (benign or malignant).
  8. Genetic pathologies (corneal dystrophy, degeneration).
  9. Glaucoma (high intraocular pressure leads to the destruction of the optic nerve, then a white spot forms and vision drops to blindness).
  10. Turning in of the border of the eyelids (entropion), which leads to the eyelid rim and eyelashes coming in contact with the mucosa.

There are diseases that trigger temporary formation of a cloudy spot. For example, hepatitis. Canine hepatitis has nothing to do with the same name as a human disease, but for an animal this ailment is very dangerous. Its pathogenic agent is a certain type of adenovirus, and it also causes the formation of a whitish film. Fortunately, in a few days the spot disappears.

Remedial Measures

If a dog has white film forming on its eyes, it means that a visit to the vet is inevitable. To restore the vision of a four-legged friend, or at least to save what can be saved, you need to find the underlying cause of the problem. Some pathologies can be eliminated surgically with the subsequent occupational therapy: torsions, mechanical injuries, foreign bodies in the eye, etc. Upon diagnosing diseases, a treatment regimen, medical therapy, and washing are prescribed.

The most common cause of leucoma is mechanical damage. Which makes sense, because the dog, be it small or large, young or old, cannot resist getting into the bushes despite the sharp branches, get into fights with other pets or neighbor dogs or cats. The task of the dog’s guardian is to prevent it from harming itself too much, that is, to ensure strict control when outdoors, regularly take care of the visual organs of the animal, and consult a vet with any atypical manifestations on an instant’s notice.
