The Effect of Temperature Changes in Vitreoretinal Surgery.

Area of Science:

• Ophthalmology
• Biomedical Engineering
• Surgical Technology

Background:

• Temperature is an emerging factor in medical and healthcare applications.
• Understanding intraocular temperature dynamics is crucial for advanced surgical techniques.

Purpose of the Study:

• To review the effects of temperature on pars plana vitrectomy.
• To analyze the interplay of intraocular pressure, viscosity, and temperature for tamponade manipulation.

Main Methods:

• Literature review of intraocular temperature studies.
• Application of physics equations to explain temperature effects on endotamponades.
• Development of a pressure-temperature operating diagram.

Main Results:

• Vitreous cavity fluid circulation maintains a near-room temperature.
• Endolaser, air infusion, and silicone oil increase intraocular temperature.
• Temperature variations are clinically significant for tamponade rheology control.

Conclusions:

• Intraocular temperature fluctuates significantly during vitreoretinal surgery.
• Temperature modulation impacts tamponade rheology.
• Intraoperative temperature control offers neuroprotection and influences tamponade properties.
