Cairn terriers with ocular melanosis (OM) accumulate large, heavily pigmented melanocytes in the anterior uvea.  |  He will want to know the symptoms you have noticed and the timeline of when they started. The trabecular meshwork is responsible for normally draining the aqueous humor from the eye. sclera also becomes pigmented and pigment can be found in the meninges around the optic nerve. Characterization of ocular melanosis in dogs. Melanomas in or around a dog’s eyes are usually benign and rarely have a chance of metastasizing. CONCLUSIONS: Ocular melanosis in Cairn Terriers is characterized by an infiltration of pigment-laden cells predominantly, but not exclusively, within the anterior uvea and anterior sclera. An inherited disease that affects Cairns, the first known cases of this disorder was diagnosed in the United States in 1984. Hypothyroidism is an abnormality of the thyroid gland leading to a reduction in the dog’s metabolic state. Nevi can be observed and referred if they change in size. The melanocytes in ocular … Pigment dispersion on the anterior lens capsule can be noted both periph - erally (arrows) and centrally (asterisk).Examination with a slit lamp revealed numerous pigmented cells floating in the anterior chamber. Aqueous humor is continuously being produced in the eye. Conjunctival … Three dogs developed uveal melanocytic neoplasms. Normal intraocular pressure in the dog is 10-25 mm Hg. This site needs JavaScript to work properly. This term ignores the fact that pigments other than melanin (such as hemoglobin or the soluble pigment in corneal sequestra of cats) may cause opacification of the cornea; therefore corneal melanosis is the preferred term. The abnormal deposits of melanocytes clog the trabecular meshwork, which is unable to drain the buildup of aqueous fluid. A minority of aqueous (~15%) bypasses the aqueous plexus and reaches the scleral venous plexus via the choroid and suprachoroidal space. The veterinarian may perform a pupillary light reflex test using a penlight. The dog will be sent home with a cone so that he does not scratch at the incisions and/or eyes. © 2020 Wag Labs, Inc.

Earlier iris melanomas in dogs can be successfully treated using diode laser photocoagulation with excellent results and preservation of vision. In that breed, pedigree analysis suggests the trait has an autosomal dominant mode of inheritance. To rule out ocular tumors, the veterinarian may suggest skull x-rays. The pigment is a result of melanocytes, or pigmented cells, inappropriately replicating and spreading over the iris surface. This is also a condition that is part of the GDC Registry.
