How is the sleeve test performed to determine photosensitivity?

The sleeve test is a method used to determine a patient's photosensitivity by progressively increasing the doses of light exposure. By starting with a low level of laser dosage and then systematically increasing it, practitioners can observe the patient's reaction to the light. This gradual approach helps identify the threshold at which the patient may experience an adverse reaction, thus allowing for safe treatment planning that takes individual sensitivity into account.

Using multiple treatments simultaneously, applying a single dosage without variation, or maintaining a uniform dosage across various areas would not provide the necessary information about a patient's specific sensitivity levels. Therefore, the correct procedure involves the methodical adjustment of doses to accurately gauge how a patient responds to varying levels of exposure.
