Summary
Toy Poodles, Cocker Spaniels, and Bichon Frises are the most common canine breeds affected by cataracts in Rio de Janeiro. Early screening for inherited eye conditions like cataracts is crucial before breeding dogs.
Area of Science:
- Veterinary Ophthalmology
- Canine Genetics
Background:
- Cataracts are a common cause of vision loss in dogs.
- Certain canine breeds exhibit a higher predisposition to developing cataracts.
Purpose of the Study:
- To identify the most prevalent dog breeds affected by cataracts in Rio de Janeiro.
- To analyze the age distribution of cataract cases in different breeds.
Main Methods:
- Retrospective study of 303 dogs with cataracts.
- Data collected from the Ophthalmology Service of Policlínica Veterinária Botafogo (January 2005 - June 2008).
- Evaluation of breed and age in affected animals.
Main Results:
- Toy Poodles were the most frequently affected breed (13.8%), with a mean age of 8.2 years.
- Cocker Spaniels and Bichon Frises were also commonly affected.
- A high percentage (33.3%) of Bichon Frises were diagnosed with cataracts.
Conclusions:
- Toy Poodles are a popular breed in Rio de Janeiro and are significantly affected by cataracts.
- Late-onset cataracts in Toy Poodles may allow affected dogs to reproduce before diagnosis.
- Screening for inherited ocular abnormalities, such as cataracts, is vital before canine breeding programs.

01:22Photoreceptors and Visual Pathways
At the molecular level, visual signals trigger transformations in photopigment molecules, resulting in changes in the photoreceptor cell's membrane potential. The photon's energy level is denoted by its wavelength, with each specific wavelength of visible light associated with a distinct color. The spectral range of visible light, classified as electromagnetic radiation, spans from 380 to 720 nm. Electromagnetic radiation wavelengths exceeding 720 nm fall under the infrared category, whereas...

DefinitionDiabetic retinopathy is a microvascular complication of diabetes affecting the retinal blood vessels.Risk FactorsDiabetic retinopathy is present in almost all individuals with type 1 diabetes and more than 60% of those with type 2 diabetes after two decades of disease.The risk increases with poor glycemic control, hypertension, dyslipidemia, smoking, pregnancy, and puberty.Although cataracts and glaucoma are also more frequent in people with diabetes, retinopathy remains the leading...
01:28Toxoplasmosis
Toxoplasmosis, a zoonotic disease caused by the protozoan Toxoplasma gondii, poses significant public health challenges globally due to its high seroprevalence and varied clinical manifestations. As an obligate intracellular parasite, T. gondii can infect all warm-blooded vertebrates, but felids are its only definitive hosts, shedding unsporulated oocysts into the environment. Humans typically acquire the infection through ingestion of tissue cysts in undercooked meat or oocysts from...
01:28Rabies
Rabies is a lethal zoonotic disease caused by a single-stranded, negative-sense RNA virus of the Lyssavirus genus, within the family Rhabdoviridae. Its primary mode of transmission to humans is through bites or saliva-contaminated scratches from infected mammals such as dogs, bats, raccoons, or foxes. Transmission can also occur if infectious saliva contacts abraded skin or intact mucous membranes, including the conjunctiva.Viral Entry and Early ReplicationOnce introduced at the bite or scratch...
