Visual training system 4: a promising adjuvant therapy for ocular accommodative function and visual acuity...

Area of Science:

• Ophthalmology
• Vision Science
• Pediatric Optometry

Background:

• Refractive amblyopia is a common cause of reduced vision in children.
• Conventional treatments for refractive amblyopia have limitations in fully restoring visual function.

Purpose of the Study:

• To evaluate the therapeutic efficacy of Visual Training System 4 (VTS4) as an adjunctive treatment for refractive amblyopia.
• To compare visual acuity, accommodative function, and convergence in patients receiving VTS4 plus conventional therapy versus conventional therapy alone.

Main Methods:

• A randomized controlled trial involving 82 patients (142 eyes) with refractive amblyopia.
• Patients were divided into a control group (conventional treatment) and an observation group (conventional treatment + VTS4).
• Outcomes assessed included best-corrected visual acuity (BCVA), accommodative function, and ocular convergence.

Main Results:

• The VTS4 group showed a significantly higher total effective rate (86.49%) compared to the control group (66.18%).
• Superior BCVA and normal binocular fusion rates were observed in the VTS4 group at 3 and 6 months.
• VTS4 improved accommodative flexibility, amplitude, and convergence functions, with no significant changes in refractive error or axial length.

Conclusions:

• VTS4 is an effective adjunctive therapy for refractive amblyopia.
• The system significantly enhances visual acuity, accommodative ability, and convergence.
• VTS4 shows strong clinical applicability and potential for improving outcomes in amblyopia treatment.
