A bipolar coaxial microprobe for safe transvitreal diathermy

Area of Science:

• Ophthalmology
• Surgical Instrumentation
• Retinal Surgery

Background:

• Traditional diathermy probes pose risks for delicate retinal structures.
• Precise coagulation near critical areas like the optic nerve is challenging.

Observation:

• A novel 22-gauge transvitreal bipolar diathermy microprobe was developed.
• The probe utilizes a coaxial principle for localized current flow.
• Its small size and end-on coagulation minimize collateral thermal damage.

Findings:

• The microprobe enables safe application of diathermy to superficial retinal vessels.
• Effective coagulation was achieved close to the optic nerve head.
• Three clinical cases demonstrated the instrument's utility.

Implications:

• This microprobe offers enhanced safety and precision in retinal diathermy.
• It expands treatment options for vascular conditions affecting the retina.
• Further adoption may reduce complications associated with retinal vessel treatment.
