Incidence and Risk Factors for Ciliochoroidal Detachment Following Preserflo MicroShunt Implantation

Area of Science:

• Ophthalmology
• Glaucoma Surgery
• Anterior Segment Surgery

Background:

• Glaucoma management often requires surgical intervention to reduce intraocular pressure (IOP).
• The Preserflo MicroShunt (PFM) is a device used in glaucoma surgery.
• Ciliochoroidal detachment (CCD) is a potential postoperative complication following ocular surgery.

Purpose of the Study:

• To investigate the incidence of ciliochoroidal detachment (CCD) after Preserflo MicroShunt (PFM) implantation.
• To identify factors associated with the development of CCD following PFM implantation.

Main Methods:

• A cohort of 83 eyes undergoing PFM implantation (with or without cataract surgery) was studied.
• Anterior segment optical coherence tomography (AS-OCT) was used to evaluate CCD postoperatively.
• Multiple logistic regression analysis was performed to determine associated factors.

Main Results:

• Ciliochoroidal detachment (CCD) occurred in 67.5% of eyes.
• CCD was most frequent in the early postoperative period, decreasing significantly by 3 months.
• Lower intraocular pressure (IOP) and shorter axial length were significantly associated with CCD.

Conclusions:

• Ciliochoroidal detachment (CCD) is a common complication following Preserflo MicroShunt (PFM) implantation.
• Short axial length and postoperative hypotony (IOP ≤6 mmHg) are significant risk factors for CCD.
• Close monitoring for CCD is recommended after PFM implantation.
