PURPOSE OF REVIEW: To provide a concise review of the oculoplastic manifestations of ocular graft versus host disease (GVHD), and to discuss their management. RECENT FINDINGS: Ocular GVHD occurs as a common immune-mediated complication of hematopoietic stem cell transplantation that presents as a Stevens-Johnson-like syndrome in the acute phase or a Sjögren-like syndrome in the chronic phase. Cicatricial conjunctivitis may be underreported in ocular GVHD. The spectrum of oculoplastic manifestations includes GVHD of the skin, cicatricial entropion, nasolacrimal duct obstruction, and lacrimal gland dysfunction...

Background Eyes with severe corneal opacifications and insufficient prognosis for high-risk corneal transplantation can be considered for the implantation of a Boston-keratoprosthesis. Since 2013, this technique of "artificial" corneal replacement is provided to high-risk eyes at the Department of Ophthalmology, University of Cologne and for 9 years at the University of Salzburg. In the meantime, a type I Boston keratoprosthesis (BI-KPro) has been implanted in 24 eyes in Cologne and in 28 eyes in Salzburg. Methods In this article, results and complications according to BI-KPro are discussed, both from the literature in PubMed, as well as from our own experiences...

BACKGROUND: Corneal anesthesia is a rare and challenging condition, particularly in young children. The insensate cornea leads to abnormal epithelial cell metabolism and loss of trophic influences supplied by the corneal nerve fibers. This results in recurrent spontaneous epithelia erosion and eventual loss of sight. Corneal reinnervation is a definitive treatment option for neuropathic keratitis. The outcome measures in young children following corneal sensitization are different to adults as esthesiometry is unachievable...

Cultivated cell spheroid transplantation is widely studied as a means of facilitating tissue regeneration. Chitosan biomaterial has been shown to promote keratocyte aggregation and multicellular spheroid formation. Herein, we provide further evidence on application of bioengineered keratocyte spheroids for corneal stromal tissue engineering. In an allogeneic rabbit model of stromal destruction caused by bacterial keratitis, the corneas were intrastromally injected with isolated keratocyte suspensions or aggregated spheroid grafts at same cell number...

Cases of ocular trauma with vegetative matter are commonly encountered in ophthalmic practice in India. Many of these present with keratitis/corneal ulceration, of which fungi have a predominant share. We report a case of fungal keratitis and graft infection with Paecilomyces lilacinus, which was successfully treated with topical and systemic Voriconazole. A farmer presented with corneal ulcer and hypopyon in left eye following vegetative trauma during farming. A provisional diagnosis of fungal corneal ulcer was made based on clinical features and topical anti-fungal therapy with Natamycin was initiated...
