Glaucoma in pets causes vision loss through elevated intraocular pressure (IOP). Early diagnosis via tonometry and treatments like medication or surgery are crucial for managing this common eye disease in cats and dogs.

Area of Science:

  • Veterinary Ophthalmology
  • Ocular Pathology

Background:

  • Glaucoma, characterized by elevated intraocular pressure (IOP), can lead to severe ocular conditions including blindness in both cats and dogs.
  • Primary glaucoma affects certain dog breeds and cats, while secondary glaucoma often arises from uveitis or neoplasia in these animals.

Purpose of the Study:

  • To highlight the importance of tonometric evaluation for early glaucoma diagnosis and management in veterinary patients.
  • To outline current medical and surgical therapeutic strategies for managing glaucoma in dogs and cats.

Main Methods:

  • Review of clinical signs associated with elevated IOP, including conjunctivitis, mydriasis, corneal edema, lens luxation, and buphthalmos.
  • Discussion of diagnostic approaches emphasizing tonometry for early detection.

  • Overview of medical management using topical demecarium bromide and timolol maleate, and systemic dichlorphenamide.
  • Description of surgical intervention, specifically transscleral cyclophotocoagulation, for refractory cases.

    • Main Results:

    • Elevated IOP is the direct cause of various pathological changes leading to vision impairment and blindness.
    • Tonometric evaluation is critical for timely diagnosis and intervention.
    • Medical therapies provide maintenance treatment, while surgical options exist for advanced or medication-resistant cases.

    Conclusions:

    • Effective management of glaucoma in cats and dogs relies on early diagnosis through tonometry and appropriate application of medical or surgical treatments.
    • A combination of pharmacological and surgical interventions can help preserve vision and manage IOP in affected animals.
