The effect of trabeculectomy and glaucoma drainage device implantation on postural intraocular pressure changes in glaucomatous eyes.

Ahmed valve surgery significantly reduces postural IOP response as compared with medically treated controls. There was no significant difference between Ahmed valve and trabeculectomy in terms of their effect on the postural IOP change.

Intraocular pressure spikes after gonioscopy-assisted transluminal trabeculotomy (GATT).

They most commonly appear during the first two post-operative weeks and usually resolve with topical and systemic IOP-lowering treatment. The continuation of IOP-lowering medications after GATT is recommended to lower the risk of IOP spikes.
