[Asteroid hyalosis in the dog].

Area of Science:

• Ophthalmology and Veterinary Medicine

Background:

• Asteroid hyalosis is a rare degenerative condition affecting the vitreous body of the eye.
• It is characterized by the presence of numerous small, spherical bodies within the vitreous.

Observation:

• Ophthalmoscopic examination reveals these bodies as brilliant, star-like structures.
• Two distinct cases of asteroid hyalosis in dogs are presented in this report.

Findings:

• Histochemical analysis identified the spherical bodies as a complex of calcium and lipids.
• The precise etiology of asteroid hyalosis remains unknown in veterinary cases.

Implications:

• The condition is typically asymptomatic and does not appear to cause significant visual impairment in affected dogs.
• Current conservative treatments have not shown efficacy in influencing the progression of asteroid hyalosis.
