Human chorioretinal biopsy under controlled systemic hypotensive anaesthesia
The British Journal of Ophthalmology
|August 1, 1980
Summary
This study presents a simplified retinal and choroidal biopsy technique. Controlled hypotension minimizes bleeding and prevents vitreous loss during ocular biopsies.
Area of Science:
- Ophthalmology
- Surgical Techniques
- Ocular Pathology
Background:
- Retinal and choroidal biopsies are crucial for diagnosing ocular diseases.
- Existing biopsy techniques can be complicated and prone to complications like bleeding and vitreous loss.
Observation:
- A simplified biopsy technique was applied to five human volunteers.
- The procedure was performed before eye enucleation for malignant melanoma or during glaucoma surgery.
Findings:
- Employing controlled systemic hypotension with mannitol and sodium nitroprusside in three cases resulted in minimal bleeding and no vitreous loss.
- In two cases without hypotension, significant bleeding occurred, though vitreous loss was still avoided.
Implications:
- This simplified technique, particularly with controlled hypotension, offers a safer and more effective method for retinal and choroidal biopsies.
- Improved biopsy methods can enhance diagnostic accuracy for various intraocular conditions.
- Further research may refine this technique for broader clinical application in ophthalmology.
