Glaucoma Group Therapy: Managing AlloFlo Uveo Device Failure

Overview

At the 2025 AAO meeting, a challenging glaucoma case involving the AlloFlo Uveo superchoroidal device was discussed. The patient initially responded well but developed a significant intraocular pressure spike due to cleft closure, ultimately requiring a tube shunt for pressure control.

Background

Glaucoma management often involves surgical interventions to reduce intraocular pressure and prevent optic nerve damage. The AlloFlo Uveo device is a superchoroidal implant designed to lower eye pressure in patients who refuse traditional incisional surgery. However, device-related complications such as cleft closure can lead to pressure spikes, necessitating alternative surgical approaches.

Data Highlights

The patient experienced a massive eye pressure spike at week 3 post-AlloFlo Uveo implantation due to cleft closure. Initial management was conservative due to the patient's refusal of incisional surgery, but ultimately a tube shunt was required to achieve adequate pressure control.

Key Findings

• The AlloFlo Uveo device can provide initial intraocular pressure reduction in glaucoma patients.
• Cleft closure is a potential complication leading to significant pressure spikes post-implantation.
• Conservative management may temporize pressure elevation but may not suffice long-term.
• Tube shunt surgery remains an effective rescue option when device failure occurs.
• Patient preferences can influence surgical decision-making and timing of interventions.

Clinical Implications

Clinicians should monitor closely for cleft closure and pressure spikes following AlloFlo Uveo implantation. Early recognition and timely intervention, including consideration of tube shunt surgery, are critical to prevent glaucomatous progression. Patient counseling regarding potential complications and surgical options is essential.

Conclusion

The AlloFlo Uveo device offers a non-incisional option for glaucoma surgery but carries risks such as cleft closure leading to pressure spikes. Tube shunt surgery remains a valuable fallback to achieve pressure control when device failure occurs.
