In Direct ECT, the intraocular tension is
**Core Concept**
Direct Electroconvulsive Therapy (ECT) involves the administration of a generalized seizure through the application of electrical currents to the brain. The procedure is typically used to treat severe depression, mania, and other psychiatric conditions that have not responded to other treatments. The goal of Direct ECT is to induce a seizure that will stimulate the brain and alleviate symptoms.
**Why the Correct Answer is Right**
In Direct ECT, the intraocular tension increases due to the increase in intracranial pressure (ICP) during the seizure. This increase in ICP is a result of the contraction of extraocular muscles and the dilation of blood vessels in the brain. As the ICP rises, it exerts pressure on the globe of the eye, leading to an increase in intraocular tension. This increase in intraocular tension is a transient effect that resolves once the seizure has ended.
**Why Each Wrong Option is Incorrect**
**Option A:** This option is not applicable to Direct ECT, as the procedure does not involve the use of anesthesia or sedation that would affect intraocular tension.
**Option B:** This option is incorrect because the increase in intraocular tension in Direct ECT is due to the increase in ICP, not a decrease.
**Option C:** This option is incorrect because the increase in intraocular tension in Direct ECT is a transient effect that resolves once the seizure has ended, not a permanent change.
**Clinical Pearl / High-Yield Fact**
It is essential for anesthesiologists and ECT technicians to monitor intraocular pressure during Direct ECT to avoid any potential complications.
**Correct Answer: B. Increased**
