History of concomitant intraocular surgery with GDD implantation may be a potential risk factor for future erosions.

Subjects who had undergone either trabeculectomy or tube shunt surgery showed a similar IOP response to the WDT. Subjects on systemic antihypertensive medications experienced significantly greater IOP fluctuations during the test.

In cases of asymmetric glaucoma, SD-tVEP results correlate significantly with the level of VF damage as measured by MD. In the eyes with more advanced VF loss, reduced SD-tVEP amplitude was associated with decreased macular thickness on OCT. These findings suggest that SD-tVEP may be a fast and objective method to assess or screen for functional damage in glaucomatous eyes.

There is currently no technology that has been approved for use to allow for continuous monitoring of IOP fluctuations. New experimental technology being developed and currently undergoing clinical trials has demonstrated potential for changing the diagnosis and management of glaucoma.
