Summary
Repetitive transorbital alternating current stimulation (rtACS) improved vision in a patient with optic nerve atrophy. This non-invasive treatment enhanced visual field detection and perimetric thresholds, offering new hope for vision recovery.
Area of Science:
- Neuroscience
- Ophthalmology
- Medical Devices
Background:
- Optic nerve damage often results in visual field defects with limited recovery potential.
- Current treatments for optic nerve damage have shown minimal success in restoring vision.
Observation:
- A patient with severe vision loss due to optic nerve atrophy underwent repetitive transorbital alternating current stimulation (rtACS).
- The treatment involved daily sessions of rtACS applied to the damaged optic nerve for 10 days, inducing phosphenes.
Findings:
- Following rtACS treatment, the patient demonstrated a significant increase in the detection ability of super-threshold stimuli (from 3.44% to 17.75%).
- Mean perimetric threshold improved from 0 dB to 2.21 dB, indicating enhanced visual function.
Implications:
- rtACS may promote vision recovery by enhancing neuronal synchronization and synaptic transmission in the visual pathway.
- This non-invasive neuromodulation technique shows potential as a novel therapeutic approach for vision impairment due to optic nerve damage.

01:27Open Angle Glaucoma: Treatment
In open-angle glaucoma, the iridocorneal angle remains open, but the trabecular meshwork becomes stiff, slowing down the outflow of aqueous humor. This causes a buildup of aqueous humor in the anterior chamber, leading to a sudden increase in intraocular pressure. The treatment for open-angle glaucoma focuses on reducing the elevated intraocular pressure by either decreasing the secretion of aqueous humor or increasing its outflow.

01:28Angle Closure Glaucoma: Treatment
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...
