On multivariate analyses, RA and GVHD were still significant risk factors. Gender, age and meibum viscosity were not significantly associated with epithelial staining grade improvement. CONCLUSIONS Overall, a high rate of corneal epithelial improvement was achieved. Nevertheless, there is an unmet need for more effective measures to reduce epitheliopathy in severe dry eye, especially in patients with systemic immune-mediated disease. © Author(s) (or their employer(s)) 2020.

Japan has been tackling HTLV-1 infection and has made remarkable progress. In ophthalmology, awareness of the association between HTLV-1 infection and uveitis has been increasing since the 1990s, when the relationship was first established. Here, we describe a nationwide survey and analysis of the current state of medical care for HTLV-1-associated uveitis (HAU) at ophthalmic facilities in Japan. METHODS A questionnaire survey covered all university hospitals in Japan that were members of the Japanese Ophthalmological Society and all regional core facilities that were members of the Japanese Ocular Inflammation Society. Survey data were collected, and nationwide data on the state of medical care for HAU were tallied and analysed. RESULTS Of the 115 facilities, 69 (60.0%) responded. HAU was most commonly diagnosed 'based on blood tests and characteristic ophthalmic findings'. Overall, 86.8% of facilities perform testing for HTLV-1 antibodies during medical care for diagnosing uveitis, with 58.3% routinely performing testing. Facilities with experience in providing medical c
