The evidence levels for diagnosis and treatment of ocular cGVHD are low, and most of the treatment options are based on empirical knowledge. Topical immunosuppression, for example, with cyclosporine, represents a promising strategy to reduce inflammation and dryness in ocular cGVHD. Further clinical trials are necessary to elucidate risk factors for eye manifestation, complications, and visual loss and to evaluate staging criteria and diagnostic and therapeutic measures for ocular cGVHD.
Despite extensive similarities in basement membrane composition between amniotic and corneolimbal epithelia, the lack of limbus-specific environmental factors argues against the potential of denuded amniotic membrane as a surrogate niche for limbal stem cells but supports its suitability as a substrate to promote the formation of a well-differentiated stratified corneal epithelial equivalent for tissue engineering strategies.
The purpose of the study was to validate a recently proposed new grading system for ocular manifestations of chronic graft-versus-host disease (cGVHD). Diagnosis of cGVHD was based on the NIH consensus criteria. In addition, a grading scale was applied, which has been developed by the German-Austrian-Swiss Consensus Conference on Clinical Practice in cGVHD. Sixty-six patients (male n = 46, female n = 20, mean age 48 years) with ocular cGVHD were included. Application of the proposed Consensus Conference grading revealed inflammatory activity in all patients with mild (33 %), moderate (44 %), or severe inflammation (23 %). Clinical scoring by the NIH scoring system showed that 6 % of patients had mild symptoms; 59 % of patients had moderate dry eye symptoms partially affecting activities of daily living, without vision impairment; and 35 % of patients had severe dry eye symptoms significantly affecting daily activities. Clinical characterization and grading by the Consensus Conference grading scale revealed that ocular cGVHD (1) frequently leads to severe ocular surface disease based on impaired function of the lacrimal glands and involvement of cornea, conjunctiva, and lids; (2) is mostly associated with ongoing inflammatory activity; (3) often leads to functional impairment and reduced quality of life; and (4) is associated with an increased risk for severe, sight-threatening complications.
The present survey revealed representative data because of the acceptable return rate and participating residents from all different educational levels (1st to 5th year). The survey can therefore help to characterize the current situation of residents in ophthalmology in Germany and to develop demand-oriented possibilities for improvement.
Interferon (IFN) beta is commonly used in the treatment of multiple sclerosis. Thromboembolic complications may be associated with this therapy. We describe a case of branch arterial occlusions combined with central vein occlusion in a female patient who had undergone IFN beta therapy for 10 years. Thromboembolic and cardiovascular risk factors responsible for this event were excluded. The appearance of retinal vein and artery occlusions in our patient indicates an association with the long-term use of IFN beta.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
