Model Predictive Temperature Control for Retinal Laser Treatments.

Article Synopsis
- Manual adjustment of laser power in retinal therapies is inefficient and can lead to inconsistent treatment effects, while automatic temperature control ensures uniform heating across different areas, which is vital for safe procedures.
- Utilizing a model predictive controller and an extended Kalman filter, real-time temperature monitoring enhances the precision of retinal laser treatments on porcine eye explants.
- The results indicate that the closed-loop control approach not only maintains consistent lesion sizes despite varying tissue absorption but also minimizes the risks of over- and undertreatment, showcasing its potential to improve retinal therapies for various conditions.
Purpose: Subdamaging thermal retinal laser therapy has the potential to induce regenerative stimuli in retinal diseases, but validated dosimetry is missing. Real-time optoacoustic temperature determination and control could close this gap. This study investigates a first in vivo application.

Unlabelled: New procedure of vowel acoustic space (VAS) (of vowel acoustic triangles) transformation for the purpose of characterization of vowel production in individuals with long-term hearing loss (HL) was developed.
Objective: To characterize VAS of adult Russian speakers with long-term HL using newly developed acoustic indicators.
Material And Methods: Recordings of sustained Russian cardinal vowels /a/, /i/, /u/ of 10 women and 10 men with long-term HL were acoustically analyzed.
The effects of septoplasty and sinus lifting simulation in rats on changes in the frequency domain of heart rate variability were compared. In the early postoperative period, the low-frequency component increases, and the high-frequency component decreases. The VLF range also increased.
