AI Article Synopsis
- The study evaluated the effectiveness of a sutureless dehydrated amniotic membrane treatment for persistent epithelial defects (PED) in patients who had not benefited from previous treatments.
- Nine eyes from eight patients, primarily suffering from limbal stem cell deficiency, were treated, resulting in an 89% success rate for PED resolution within approximately 18 days.
- Vision significantly improved for the participants, with further research suggested to determine the long-term safety and effectiveness of this treatment.
Article Abstract
Purpose: To report outcomes of a sutureless dehydrated amniotic membrane for persistent epithelial defects (PED).
Methods: This retrospective study included consecutive patients with a PED (⩾14 days) treated with a sutureless dehydrated amniotic membrane and bandage contact lens (BCL). Included were patients with an epithelial defect that did not respond to treatment with a BCL. Excluded were patients with a follow-up time of less than 3 months.
Results: Nine eyes of eight patients with a mean age of 54.6 ± 10.9 years (range 38-73 years) were included in this study. The main etiology of the PED was limbal stem cell deficiency ( = 5/9) due to Stevens-Johnson Syndrome ( = 2/5), glaucoma procedures ( = 1/5), graft-versus-host disease ( = 1/5) and severe allergic reaction ( = 1/5). Additional etiologies included neurotrophic cornea ( = 2/9), post keratoplasty and severe dry eye disease ( = 2/9). Time from PED presentation to amnion treatment was 65.9 ± 60.6 days (range 15-189 days) with the area of the PED being 11.0 ± 12.2 mm (range 1.0-36.0 mm). The amnion was absorbed within 2 weeks in 100% of the cases. Following insertion of the amnion, resolution of the PED was achieved in 8/9 eyes (89%) without the need for additional interventions within 17.8 ± 9.6 days (range 7-35 days). LogMAR BCVA improved from 0.94 ± 0.88 to 0.37 ± 0.25 ( = 0.036) with no complications or recurrences recorded.
Conclusions: Sutureless dehydrated amniotic membrane achieved resolution of PEDs secondary to various etiologies in 89% of eyes with a significant improvement in vision demonstrated. Further studies are needed to assess long term safety and effectiveness.

: Dry Eye Disease (DED) is a chronic condition characterised by tear film instability and ocular surface disruption, significantly impacting patients' quality of life. This study aimed to provide top-level clinical evidence for the long-term efficacy of dehydrated amniotic membrane (dAM, Omnigen) delivered via a specialised bandage contact lens (sBCL, OmniLenz) for managing moderate-to-severe DED. : This randomised controlled trial (NCT04553432) involved 93 participants with moderate-to-severe DED, randomised to receive a 1-week bilateral treatment of either dAM (17 mm diameter with 6 mm central 'window') applied under a sBCL or sBCL alone.

Purpose: To report the outcomes of using a sutureless human amniotic membrane dehydrated matrix (HAMDM) in the management of a range of ocular surface conditions utilizing a digital ocular surface disease assessment tool.
Methods: Two UK NHS Trusts - Queen Victoria Hospital Foundation Trust (East Grinstead and Maidstone) and Tunbridge Wells Trust (Kent) - prospectively treated patients with ocular surface disease with sutureless HAMDM. The patient cohort was assessed for resolution of epithelial defects, ocular surface inflammation, and best-corrected visual acuity pre- and posttreatment.

Purpose: To assess changes in symptoms and ocular surface signs following a bilateral sutureless treatment of dehydrated amniotic membrane (dAM) under a specialised bandage contact lens (sBCL) in patients with moderate-to-severe dry eye disease (DED).
Patients And Methods: In this prospective pre-post interventional study, 35 patients diagnosed with moderate-to-severe DED, with an Ocular Surface Disease Index (OSDI) score >30 on current treatment, were enrolled. Assessments were conducted at baseline (day -30), after 30 days run-in with no additional treatment (day 0 - control), and 30 days post sBCL+dAM treatment (day 30 - treatment).

Purpose: The purpose of this study was to investigate the efficacy and indications of using dried gamma ray-sterilized amniotic membrane (AM) transplantation with bandage contact lenses for the in-office sutureless treatment of various ocular surface diseases.
Methods: This study retrospectively included 56 eyes of 52 patients with various ocular surface diseases treated with sutureless dehydrated AM-assisted therapeutic contact lenses. The patients were followed up and assessed 1, 2, and 4 weeks after the treatment, and the therapeutic contact lenses were removed after 1 or 2 weeks.

Purpose: To evaluate a novel sutureless glueless technique using a triple-layer dehydrated amniotic membrane (TLDAM) for pterygia excisions in surgical time, postoperative pain, epiphora, irritation, and FBS.
Methods: Twenty eyes with pterygia underwent excision with mitomycin C. The conjunctival defect was closed with TLDAM placed on the dried scleral bed with the edges of the amniotic membrane tucked under the edges of the conjunctival defect.
