Analyzing the Difference of Human Rights Consciousness Based upon Human Rights Educational Experience of the North Korean Refugees

Purpose: To investigate the efficacy of amniotic membrane transplantation (AMT) in patients who were diagnosed with necrotizing scleritis after pterygium excision and who were refractory to systemic corticosteroid and immunosuppressive therapy. Methods: Six patients who had persistent scleral melting with systemic corticosteroid or immunosuppressive agents underwent double AMT as a permanent patch graft and temporary overlying barrier. Postoperatively, the symptom improvements, reepithelization times and visual acuity changes were evaluated. Results: Choroidal detachment was detected in two patients preoperatively. In all patients, ocular pain improved at 4.73.1 days, and reepithelization of the scleral lesions was completed at 13.28.1 days postoperatively. Choroidal detachment in two patients disappeared at postoperative 2 and 8 days. Completeremission was found in 5 of the 6 eyes (83.3%). One eye which achieved full epithelization in the necrotic area experienced recurrent nodular scleritis in another quadrant, resulting in remission after changing the regimen of immunosuppressive agents. Mean values of initial and final visual acuities were 0.898 logMAR and 0.428 logMAR, respectively, and the visual acuities improved in all patients. Conclusions: AMT is effective in promoting reepithelization of the necrotic area, resulting in complete remission of necrotizing scleritis in patients who were refractory to systemic corticosteroid or immunosuppressive therapy.
