In this retrospective review of 38 eyes, Talajic et al. reported a significant number of patients losing fixation loss due to end-stage glaucoma, after Boston keratoprosthesis implantation. Over a mean follow-up period of 16.5 months, 63% of 38 eyes required increased in IOP-lowering agents, mean number of glaucoma drops increased by one medication, and five patients required more glaucoma surgery. The authors suggested consideration of cyclophotocoagulation as an alternative to GDD in BKP-I patients given the associated complications.
13. Kamyar R, Weizer JS, de Paula FH, et al. Glaucoma associated with Boston type I keratoprosthesis. Cornea 2012;31:134-139. In this retrospective study of 30 eyes receiving Boston type 1 keratoprosthesis with an average follow-up of 17-19 months, Kamyar et al. reported that 20 of 30 eyes had preoperative history of glaucoma and eight of 20 eyes have had prior incisional glaucoma surgeries. Twenty-one eyes underwent concomitant glaucoma surgery along with BKP-I implantation, 14 received GDD, and seven had cyclophotocoagulation. Results supported the authors' proposition that preoperative or concomitant glaucoma surgery may improve postoperative IOP control and progression of glaucomatous optic neuropathy.

In this retrospective review of 10 patients, Panarelli et al. reported anterior segment OCT evaluation of the anterior chamber, documenting progressive synechial angle closure, likely secondary to irido-backplate contact.

Occurrences of serious posterior segment complications, such as retinal detachment (17%), choroidal detachment (17%), or sterile vitritis (14.5%), were reported in this retrospective review of 110 Boston keratoprosthesis type 1 in 98 eyes over a mean follow-up period of 28.2 months.
18. Robert MC, Pomerleau V, Harissi-Dagher M. Complications associated with Boston keratoprosthesis type 1 and glaucoma drainage devices. Br J Ophthalmol 2013;97:573-577. Robert et al. performed a retrospective study comparing loss of BCVA in patients receiving BKP-I and those receiving both BKP-I and GDD. The authors noted significant increased risks of complications, such as glaucoma progression (22%), tube occlusion-causing postoperative IOP spikes (22%), or choroidal hemorrhage (17%), as well as loss of BCVA, almost double that in the BKP-I group, in the BKP-I + GDD group. The authors recommended a complete pars plana vitrectomy in anticipation of GDD implantation to reduce the risk of vitreous incarceration within the tube.

[Accessed 28 September 2013]. In this retrospective review of 20 eyes of 20 patients undergoing pars plana GDD in combination with Boston type 1 K-Pro over an average follow-up period of 31.6 months, the authors reported a low risk of erosion and postoperative complications. Preoperative IOP was 19.8±6.3 with an average of 2.5 medications and postoperative IOP was 10±7.0 with an average of 2.1 medications.

Law et al. noted no increase in BKP-I retention failure rate or secondary complication in a retrospective series of 29 eyes (29 patients) undergoing combined GDD implantation and BKP-I placement. The authors recommended placing a longer intraocular shunt.

The prevalence of GDD-associated conjunctival erosion was corroborated by Patel et al. 2012, which was 14.6% in their series of 130 patients. Patel et al. reported 37% resolution by simply changing the contact lens diameter to reduce the mechanical trauma.

The authors found 85% agreement between the tactile and scleral pneumatonometer IOPs and 95% agreement between tactile and transpalpebral Diaton IOPs. Overall, scleral pneumotonometry yielded consistently higher IOP range than Diaton IOP and tactile estimates.
