Anomalia oczu owczarków Collie

Anomalia oczu owczarków collie (powszechnie określana jako CEA z angielskojęzycznej nazwy collie eye anomalny) jest chorobą genetyczną psów tej rasy i innych ras podatnych na CEA. U psów ras takich jak: collie długo i krótkowłose, owczarki australijskie, szetlandzkie, border collie oraz psów Lancashire heeler, whippet długowłosy i Nova Scotia Duck Tolling retriever, z roku na rok obserwuje się wzrost zachorowań na CEA. Choroba może występować również u mieszańców.

Keratoplasty

Certain pathologic conditions lead to a loss of corneal transparency. It may lead to visual disturbance. One method of the treatment can be conventional allogenic corneal transplants (penetrating or non -penetrating keratoplasty). In veterinary ophthalmology the logistics of obtaining corneal donor tissue are complicated.

Surgical correction od evered of The Third Eyelid in a Boxer dog

Third eyelid eversion is seen most commonly in young large breed dogs. The everted cartilage appeared as an anterior folding of the leading edge of the third eyelid. The main differential diagnosis is a “cherry eye”. Both conditions cause chronic irritation of the conjunctiva and cornea, and if untreated, can lead to conjunctival edema, epiphora and keratoconjunctivitis sicca. Standard surgical method for the correction of this conditions is to remove the scrolled portion of the cartilage. In this report a case of surgical correction in four-month-old Boxer is reported step by step.

Vitreous humor and deseases

The vitreous humor is the largest structure in the eye. It is a transparent, jellylike humor that fills the posterior cavity of the eye. As a results, the vitreous functions to transmit light, to maintain the shape of the eye, and to help maintain the normal position of the retina.

Chronic superficial keratitis in dogs current methods of diagnosis and therapy

Chronic superficial keratitis (keratitis superficialis chronica) is common potentially blinding, ocular diseases of dogs. The illness proceeds with the symptoms of blood vessels ingrowing, infiltration of the fibro-vascular tissue and the corneal pigmentation which appear in bottom quadrants of cornea. It is thought to be an immunological based illness but the exact reason for chronic superficial keratitis is still unknown.

The Feline Glaucoma

Aqueous humor is produced by the ciliary body by active secretion and filtration of plasma. Most of the aqueous humor flows from the posterior chamber, through the pupil, to the anterior chamber, and exit at the iridocorneal angle into the intrascleral venous plexus. The balance between formation and drainage maintains intraocular pressure. In glaucoma the pressure in the eye increased. Prolonged or recurrent elevation of intraocular pressure lead to degeneration of the retina and optic nerve. The presence of a “red eye”, corneal edema, mydriasis, blepharospasm, blidness, and buphtalmos can be seen. Pupillary light reflex may be slow or absent.

Tonometry

Tonometry should be a routine component of an ophtalmic examination. It is an essential examination providing rapid diagnosis, especially for glaucoma or uveitis. Tonometry is noninvasive and quick and allows to take up the right treatment. To messure the intraocular pressure Schiǿtz tonometer, Tono-pen, Tonovet and air-puff tonometers can be used. Tono-pen and Tonovet are the manual devices most widely used in veterinary ophtalmology.

The most common eye diseases in cat

Many eye problems in the cat are quite different from those found in the dog, or any other animals. Corneal sequestrum, for example, appears to be unique to the cat. Ocular manifestations of systemic disease are quite common in cats and routine examination may be crucial as an aid to diagnosis. Deficiencies of taurine and thiamine can change the appearance of the ocular fundus.

Urazy gałki ocznej – nazewnictwo, klasyfikacja i rokowanie

Uraz oka zarówno dla pacjenta, jak i jego rodziny jest ciężkim przeżyciem psychicznym. Zadaniami prowadzącego lekarza w tej sytuacji są: ustalenie odpowiedniego postępowania i poinformowanie pacjenta o przebiegu leczenia oraz wymiana doświadczeń z innymi specjalistami. Na podstawie nazewnictwa BETT utworzono system klasyfikacji urazów oka. W prosty sposób przedstawiono w nim informacje o poszczególnych urazach. Umożliwia to rejestrowanie i statystyczną obróbkę danych (1,2), która pozwoliła na opracowanie skali prognostycznej urazów oka OTS (Ocular Trauma Score).

Uveitis in dog and cats

Uveitis can be defined as an inflammatory process of the uveal tract. Clinically, the iris and ciliary body usually react together, while the choroid behaves somewhat independently. Uveitis is thus generally classified into two categories: anterior uveitis or iridocyclitis and posterior uveitis or choroiditis (1).

Lens – Part I

The lens originates from surface ectoderm covering the embryo’s head. The lens is composed of an acellular capsule, epithelial cells and fibers. The postnatal lens lacks vascularization and innervations. For nutrients and removal of metabolic waste products depends on the aqueous humor. The lens is comprised of 2/3 water and 1/3 protein. Two forms of proteins have been described: soluble (cristallin) and insoluble (albuminoid). Metabolism of glucose from aqueous humor provides the main source of energy for the lens, with anaerobic glycolysis pathways, being the most important. The basic function of the lens is to focus light onto the retina producing a clear, sharp image.

Indolent Ulcer in Boxer

A case of indolent ulcer in a Boxer is described. An indolent ulcer is a ulcer which fails to heal in the expected time. These ulcers are often breed-related, develop spontaneously and may be considered to represent a primary corneal epithelial or superficial stroma dystrophy. It is caused by a failure of attachment between the basal epithelium to the underlying membrane. There are several methods that will facilitate healing; debridement, keratotomy, superficial keratectomy and medical treatment.

Poliethiological ulcerative mycotic keratitis in horse

he authors report a clinical case of poliethiological ulcerative mycotic keratitis in horse. The disease was diagnosed with mare, bay colour, aged 7 years. The ocular examination revealed in the inferior cranial quadrant of the right cornea: the superficial and deep blood vessel ingrowth, oedema, multifocal dark brown subepithelial infiltrations as well as superficial corneal ulceration with the demarcated epithelial.

Drainage devices in refractory glaucoma treatment

Drainage devices (aqueous shunts – AS) in glaucoma surgery have been improved within last 40 years. They are used in refractory glaucoma, caused by: conjunctival scarring after previous filtrating surgery, abnormalities of the irido-corneal angle, neovascular and inflammatory glaucoma, presence of corneal grafts or keratoprosthesis, previous vitreoretinal surgery.

Managements of the corneal trauma in animals

Ocular injures are unfortunately a common occurrence in animals. Appropriate detection, diagnosis and treatment decision are needed in case of corneal trauma. Treatment will vary depending on the nature of the wound. In some situations soft contact lenses may promote healing, whereas corneal lacerations may need surgical repair.
