Purpose:Glaucoma is common in patients with the Boston type 1 keratoprosthesis (KPro). Because of the inability to perform corneal applanation in KPro patients, digital palpation is currently the mainstay for assessment of intraocular pressure (IOP). The purpose of this study was to determine whether the Diaton tonometer, which estimates IOP through transpalpebral scleral indentation, can reasonably detect high IOP when compared with Goldmann applanation tonometry (GAT) in patients with ocular… 

Central corneal thickness in glaucoma

The clinical significance of CCT is well recognized in the context of glaucoma diagnosis and management, though the extent of its importance remains debatable, and corneal biomechanical properties may be more significantly associated with glauca than CCT.

Device profile of the EYEMATE-IO™ system for intraocular pressure monitoring: overview of its safety and efficacy

In glaucoma patients, the Eyemate-IO™ could be implanted safely and showed a favorable efficacy and safety profile in the first twelve months postoperatively, and the potential to achieve IOP monitoring with the Eyepad-IO seems promising.

Rapid and Accurate Pressure Sensing Device for Direct Measurement of Intraocular Pressure

This work combines a high-resolution pressure microsensor with 30- and 33-gauge Luer lock needles to provide IOP measurements via a microcontroller and USB interface to a computer and shows a linear relationship with changes in imposed pressure.

Commentary: Glaucoma following penetrating keratoplasty: A double whammy

Outcomes of cataract surgery have significantly improved in India in the past three decades, with lower incidence of corneal complications, and the quality of graft clarity has significantly improved with lamellar keratoplasty techniques, but it is not known if these improvements in outcomes and early diagnosis and management of infective keratitis have reduced the occurrence of post‐PK glaucoma.

[Treatment of vascularized high-risk eyes with a Boston keratoprosthesis].

The Boston keratoprosthesis is an alternative to conventional corneal replacement if the prognosis for allogeneic transplants is poor and postoperative management plays an important role for visual rehabilitation.

Short-term Interim Results of Clinical Outcomes and Complications After Implantation of Boston Keratoprosthesis in Japanese Patients.

In conclusion, BKpro implantation is effective and safe for Japanese patients, given the reported improvements in visual acuity and low rates of complications.

The Boston keratoprosthesis

The current indications for implantation of the BKPro have broadened and devices to reliably measure intraocular pressure and imaging modalities to provide improved visualization of intraocular structures have the potential to further improve outcomes.

Telehealth and Screening Strategies in the Diagnosis and Management of Glaucoma

Artificial intelligence will enhance the accuracy of data interpretation and inspire confidence in popularizing telehealth for glaucoma.



Evaluation and management of glaucoma after keratoprosthesis

Glaucoma is a common and permanent blinding sequelae of K-pro surgery and management is frequently surgical and typically entails placement of a GDD or cyclophotocoagulation.

Glaucoma management in Boston keratoprosthesis type I recipients

In keratoprosthesis recipients, glaucoma often leads to permanent loss of sight, and it is imperative that these patients be monitored with vigilance by a multidisciplinary team to prevent progression.

Central corneal thickness and Diaton transpalpebral tonometry

The Diaton measurements show moderate correlation with those provided by applanation tonometry, but seems to be more affected by the corneal thickness, especially in the thinnest corneas.

Transpalpebral measurement of intraocular pressure using the Diaton tonometer versus standard Goldmann applanation tonometry

Diaton cannot recommend Diaton as a substitute or alternative method for GAT for diagnosis and follow-up of patients with abnormal IOPs, but it may be helpful as a screening tool, especially for subjects whose age is between 20 and 50 years and for healthy subjects.

Glaucoma Associated With Boston Type I Keratoprosthesis

The Boston type I KPro is an effective option for management of eyes with poor prognosis for primary or repeat penetrating keratoplasty, but visual potential is limited by preoperative comorbidities; however, glaucoma development or progression of preexisting glAUcoma is a significant cause of postoperative visual loss.
