About us


Driven by the need to overcome the challenges of existing glaucoma therapies, LIQID Medical is pioneering the revolutionary concept of oculosubarachnoid shunting.


Oculosubarachnoid shunting offers the potential for a safe, predictable and highly effective glaucoma treatment solution without the complications associated with bleb creation. Oculosubarachnoid shunting is also the only treatment able to eliminate translaminar pressure. Research indicates that this holds the key to definitively preventing glaucoma.

Our work has led to multiple scientific awards and the development of highly innovative and patented ophthalmic devices. The OptiShunt and iPortVR have the potential to redefine the treatment paradigm for glaucoma.

In 2019, LIQID Medical initiated the first-in-man glaucoma treatment by oculosubarachnoid shunt insertion pilot study, the GOSSIP study. The GOSSIP study has been conducted according to ISO14155 standards at Groote Schuur tertiary academic hospital. Current 3-month trial results demonstrate that oculosubarachnoid shunting is safe and highly effective in reducing mean intraocular pressure and the number of medications used by patients.
