Nd:YAG laser treatment temporarily reduced visual acuity and caused field defects in patients. However, electroretinogram and electrooculogram tests showed no lasting changes in retinal function after the procedure.

Area of Science:

Ophthalmology
Laser Medicine
Retinal Physiology

Background:

Neodymium-doped Yttrium Aluminum Garnet (Nd:YAG) laser treatment is used in ophthalmology.
Understanding the impact of Nd:YAG laser on retinal function is crucial for patient safety and treatment efficacy.

Purpose of the Study:

To assess the functional impact of Nd:YAG laser treatment on the retina.
To evaluate changes in visual acuity, visual fields, and electrophysiological responses post-treatment.

Main Methods:

Patients underwent Nd:YAG laser treatment.
Visual acuity was measured immediately after treatment.
Electroretinography (ERG) and Electrooculography (EOG) were performed before and after treatment.
The Umazume-Ohta test was used to assess visual field defects.

Main Results:

All patients experienced a temporary decrease in visual acuity post-treatment.
ERG and EOG recordings remained unchanged, indicating no persistent retinal dysfunction.
The Umazume-Ohta test revealed temporary central or paracentral visual field defects in all subjects.

Conclusions:

Nd:YAG laser treatment can cause transient visual disturbances.
While immediate visual acuity and field defects are observed, electrophysiological retinal function appears preserved.
Further monitoring may be warranted for patients experiencing visual field alterations after Nd:YAG laser therapy.
