Summary
Hydrodissection is a simple technique that improves conjunctival flap creation for canine corneal ulcers. This method offers enhanced patient comfort and surgical ease without significant differences in outcomes compared to traditional methods.
Area of Science:
- Veterinary Ophthalmology
- Surgical Techniques
Background:
- Hydrodissection is an underutilized liquid injection technique in veterinary ophthalmic procedures.
- Conjunctival flaps are used to treat corneal ulcers in dogs.
Purpose of the Study:
- To evaluate the efficacy of hydrodissection in creating conjunctival flaps for canine corneal ulcers.
- To compare hydrodissection with conventional divulsion methods.
Main Methods:
- Seventeen dogs with deep corneal ulcers were divided into two groups: hydrodissection (G1) and conventional divulsion (G2).
- Hydrodissection involved subconjunctival injection of 0.9% sodium chloride before flap creation.
- Evaluated parameters included operative time, bleeding, ease of dissection, and post-operative complications.
Main Results:
- Hydrodissection proved to be an easy maneuver that optimized conjunctival flap construction.
- No significant differences were observed between groups in trans-operative or post-operative evaluations.
- Suture dehiscence occurred in two dogs in each group, with no statistically significant difference.
Conclusions:
- Hydrodissection facilitates conjunctival flap creation in dogs with corneal ulcers.
- The technique offers improved patient comfort and is a valuable option for veterinary ophthalmologists.
