Angle Closure Glaucoma: Treatment01:28

Angle Closure Glaucoma: Treatment

681
Angle-closure glaucoma, or closed-angle glaucoma, is an eye condition where the iris bulges out and blocks the iridocorneal angle, resulting in a buildup of aqueous humor and increased intraocular pressure. Immediate medical attention is necessary due to the sudden onset of symptoms. The treatment for angle-closure glaucoma includes short-term and long-term approaches. Short-term treatment involves using eye drops like pilocarpine to lower intraocular pressure by increasing aqueous humor...

Area of Science:

  • Ophthalmology
  • Digital Therapeutics
  • Vision Science

Background:

  • Immediate effects of augmented reality (AR) visual training on choroidal thickness (ChT) and accommodative facility (AF) are not well understood.
  • The potential of AR combined with vision restoration models for myopia prevention needs empirical validation.

Purpose of the Study:

  • To evaluate the immediate effects of a single AR visual training session on ChT and AF.
  • To assess the potential of this interdisciplinary digital therapeutic (DTx) approach for myopia intervention.

Main Methods:

  • Twenty healthy volunteers (6-13 years) were randomized into AR (n=11) or control (n=9) groups.
  • ChT and AF were measured before and after training using optical coherence tomography angiography and standard methods.
  • The AR group received a single session of AR visual training; the control group rested.

Main Results:

  • AR training significantly reduced average ChT (0-1 mm zone) from 332.85 to 324.11 µm (p=0.007).
  • Accommodative facility (AF) significantly increased from 5.05 to 8.05 cpm (p=0.004).
  • A positive correlation was found between spherical equivalent and ChT change (r=0.962, p=0.009).

Conclusions:

  • A single AR visual training session, integrated with a vision restoration model, led to short-term decreases in ChT and improved AF.
  • AR technology integrated with digital therapeutics (DTx) shows potential as a myopia intervention strategy.
  • This study highlights a novel direction for optimizing digital therapeutics in eye care.
