PURPOSE: To evaluate clinical outcomes of adjunctive treatment with homogenate human amniotic membrane eye drops (AMED) in patients with refractory ocular surface disease with dry eye (DE) manifestations.
METHODS: We retrospectively reviewed patients' medical records, ocular surface images, and instrumental data related to Schirmer I test, Oxford and Efron grading, non-invasive tear break-up time, Ocular Surface Disease Index (OSDI), adverse events, and symptom recurrence after discontinuation. All patients were assessed for safety while the efficacy analysis included patients who completed 2-month uninterrupted AMED treatment, without modification of topical or systemic therapy in the previous two months or during the treatment period.
RESULTS: A total of 160 patients were exposed to AMED. Twenty-three (14.4%) patients discontinued treatment and 25 (15.6%) showed adverse events. 112 (70%) patients [mean (SD) age 57 (16) years], 73.0% female, were included in the efficacy analysis. We observed improvement in corneal Oxford grading in graft-versus-host disease (GVHD) and limbal stem cell deficiency (LSCD) patients (P < 0.001 and P = 0.02, respectively) and conjunctival Oxford grading in GVHD, LSCD, Sjögren's syndrome (SS) and non-Sjögren's dry eye (NSDE) (P < 0.001); decreasing in Efron score in GVHD and SS (P < 0.001 and P = 0.03, respectively). Tear film stability improved across almost all groups and OSDI showed clinically modest changes. Symptoms recurrence was reported in 86.9% of patients within one month after AMED discontinuation without adverse events reported during 2-month continuous treatment.
CONCLUSIONS: Adjunctive AMED treatment was associated with objective improvements of ocular surface, with limited effects on symptoms, likely reflecting the multifactorial nature of DE manifestations across clinically and pathophysiological distinct entities.
