Vitreoretinal Complications of the Boston Keratoprosthesis

Abstract: The Boston Keratoprosthesis has allowed for visual restoration in patients with corneal blindness; however, vitreoretinal complications remain a significant cause of ocular morbidity. Retroprosthetic membranes, infectious endophthalmitis, sterile vitritis, vitreous hemorrhage, vitreous opacities, retinal detachment, cystoid macular edema, choroidal detachments, retinal vascular occlusion, and epiretinal membrane have all been described, may require the intervention of a vitreoretinal specialist, and are review… Show more

“…The multidisciplinary KPro team may face a variety of posterior segment complications including retroprosthetic membrane, infectious endophthalmitis, and retinal detachment and choroidal detachment. [4][5][6] Vitreoretinal complications may be challenging to diagnose in KPro eyes because of difficulties in visualizing the posterior pole through the small 3.35 mm central diameter stem of the keratoprosthesis. Thus, examination of the peripheral retina with traditional techniques such as indirect ophthalmoscopy with a small pupil setting is often marginal or inadequate to fully characterize posterior segment pathology, especially in the far periphery.…”

“…Although the number of eyes with prior HSV keratitis in this report is relatively small, the diagnosis of CME in 5 of the 11 eyes suggests that there is an association between the two. It is also reported to have a later onset compared with pseudophakic CME, diagnosed at a mean of 7.6 months (range, 0.67–14 months) following surgery, compared with 6 weeks 21. One eye in the HSV group was diagnosed with CME prior to Kpro implantation, which may confound the results based on our small sample size.…”

“…All had significant proliferative vitreoretinopathy [13]. Retinal detachments in the context of K-Pros are mostly either tractional or rhegmatogenous in origin and tend to have poorer outcomes [14][15][16]. Often patients do not notice any symptoms until the detachment is extensive and severe, despite close follow-up.…”
