eye treatment glaucoma of dog in noida pet clinic

Glaucoma in dogs is a serious eye disease where pressure inside the eye (intraocular pressure, IOP) rises, damaging the optic nerve and leading to vision loss or blindness if untreated. It’s often painful and requires urgent veterinary attention.

🔍 Causes of Glaucoma in Dogs

1. Primary glaucoma

   • Inherited defect in eye drainage angle → common in certain breeds (Cocker Spaniel, Basset Hound, Beagle, Chow Chow, Shih Tzu).

2. Secondary glaucoma (more common)

   • Results from another eye problem:

     • Uveitis (inflammation)

     • Lens luxation (dislocation of lens)

     • Tumors

     • Trauma or bleeding inside eye

⚠️ Symptoms

• Early signs may be subtle, but progression is fast:

  • Red, bloodshot eyes

  • Cloudy or bluish cornea

  • Dilated pupil, poor response to light

  • Squinting, excessive tearing

  • Rubbing face or pawing at eyes

  • Lethargy, loss of appetite (from pain)

  • Sudden blindness (often noticed when bumping into objects)

🩺 Diagnosis (by Vet/ophthalmologist)

• Tonometry → measures intraocular pressure (normal: 10–25 mmHg; glaucoma: often >30 mmHg)

• Ophthalmoscopy → optic nerve and retina exam

• Gonioscopy → evaluates drainage angle (for primary glaucoma)

⚕️ Treatment Options

Glaucoma cannot be cured, but treatment aims to relieve pain, preserve vision (if possible), and protect the other eye.

1. Medical management (for early/mild cases or emergencies)

• Carbonic anhydrase inhibitors (dorzolamide, brinzolamide) → reduce fluid production

• Beta-blockers (timolol) → reduce fluid production

• Prostaglandin analogs (latanoprost) → increase drainage (useful in primary glaucoma)

• Mannitol IV → emergency pressure reduction

2. Surgical options

• Cyclophotocoagulation or cyclocryotherapy → reduces fluid production

• Gonioimplant/shunts → helps fluid drain

• Enucleation (eye removal) → for blind, painful eyes (provides pain relief and good quality of life)

👁️ Management of the Other Eye

• In primary glaucoma, the second eye is often affected within months.

• Preventive eye drops may be prescribed to delay disease in the unaffected eye.

🛑 Prognosis

• Emergency! Permanent blindness can occur within hours to days if untreated.

• With early detection + proper management → vision may be saved, but lifelong treatment is usually required.

• Blind dogs can still live happy lives if pain is controlled.

✅ At-Home Care Tips

• Give eye drops exactly on schedule (delays can cause spikes in pressure).

• Minimize stress and sudden excitement (can increase IOP).

• Protect blind dogs: keep furniture in the same place, use baby gates near stairs.

• Regular check-ups with vet/ophthalmologist every 1–3 months.
