Retinal Tear Following Low-Frequency Repetitive Transcranial Magnetic Stimulation for Obsessive-Compulsive Disorder.

OBJECTIVES

Repetitive transcranial magnetic stimulation (rTMS) is a noninvasive form of brain stimulation that uses magnetic pulses to stimulate specific brain regions. Retina is being investigated whether the retina, which is also known as the brain's window to the outside world, is affected by the treatment.

METHODS

Magventure X100 device was used for the procedure. The bilateral supplementary motor area was targeted. Procedure protocol: power: 47%, repetitive rate (frequency): 1 Hz, pulses in train duration: 300, intertrain interval (waiting time): 120 seconds, number of trains: 4, total pulses: 1200. Twenty sessions of rTMS were planned for the patient. The patient was informed about the procedure, and her consent was obtained.

RESULTS

The Yale-Brown Obsessive-Compulsive Disorder Scale (YBOCS) score before the first session was 31, and the Brown Assessment Beliefs Scale (BABS) score was 5. The patient's YBOCS score after the 15th session was 14, and the BABS score was 0. After the implementation of the 15th session of the patient's treatment, retinal detachment developed in the right eye, and the treatment was terminated. As a result of the eye examination of the patient, it was determined that there was 1 horseshoe rupture and 2 hole-shaped ruptures in the lower half of the left eye.

CONCLUSIONS

Patients at risk for retinal detachment may require specialized treatment and close monitoring to prevent the condition from worsening. It is important to consult with an ophthalmologist for patients at risk for retinal detachment before TMS application.
