Aim:
To analyze the application of microbubble contrast technology in the treatment of ophthalmic diseases, mainly analyzing its advantages and existing problems.
Methods:
A total of 30 representative literatures about the application of ultrasound contrast agent in gene targeted therapy at home and abroad were collected, and focusing on sorting out the literature reporting the treatment of ophthalmic diseases with microbubble contrast technology in recent years, then recalling its advantages and problems, finally making reasonable assessment on existing problems and proposing possible solutions to the problems.
Results:
DUE TO ITS UNIQUE SAFETY AND EFFICACY, THE TREATMENT OF OPHTHALMIC DISEASES WITH MICROBUBBLE CONTRAST TECHNOLOGY HAS INCREASINGLY DRAWN THE ATTENTION OF CLINICIANS, BUT TWO RELEVANT ISSUES SHOULD BE CONSIDERED: first, the nature of contrast agent and the choice of corresponding ultrasound parameters; second, relative incidence of tissue bleeding, intravascular hemolysis, moderate or severe allergy as well as other side effects.
Conclusion:
Microbubble may become the carrier of targeted therapy, and as a kind of new non-invasive delivery system, the ultrasound contrast agent has broad application prospects, but its application in ophthalmic research is still in its initial stage and the safety of contrast-enhanced ultrasound still needs further study.
