Background: Amniotic membrane transplantation (AMT) has been used in the management of acute ocular chemical burns to promote epithelialisation, reduce inflammation and restore ocular surface integrity. The aim of this study is to analyse the morphological and functional outcomes of patients receiving AMT after ocular chemical burn.
Methods: We performed a retrospective analysis of all patients treated for acute ocular chemical burn between 1998 and 2008 in two participating centres (University of Duisburg-Essen, Germany and Royal Victoria Infirmary, Department of Ophthalmology, Newcastle University, UK). Ocular chemical burns were classified by Roper-Hall and Dua classifications.
Results: 72 eyes of 54 consecutive patients aged 37.3 years (±SD 11.6 years) were included in this cohort study. 7 chemical burns were acid burns, 61 were alkaline and 4 were of unknown origin. In 37 eyes (51.4%), AMT was applied within the first 6 days after injury. Mean follow-up time was 36.4 months (median 18.5; 1.3-117.3 months). Overall, 29 eyes (40.3%) achieved a best-corrected visual acuity of LogMAR 0.2 (0.63 decimal) or better at final visit. Complete 360° limbal stem cell deficiency (LSCD) occurred in 33 eyes (45.8%), while partial LSCD occurred in 21 eyes (29.2%).
Conclusion: AMT is an effective adjunctive treatment in the management of acute ocular chemical burns to support epithelial healing and restore ocular surface integrity with potential to improve vision. However, long-term debilitated vision remained in those with severe burns complicated by LSCD.

Numerous diseases, such as diabetic retinopathy and age-related macular degeneration, can lead to retinal neovascularization, which can seriously impair the visual function and potentially result in blindness. The presence of the blood-retina barrier makes it challenging for ocularly administered drugs to penetrate physiological barriers and reach the ocular posterior segments, including the retina and choroid. Herein, we developed an innovative bifunctional peptide, Tat-C-RP7, which exhibits excellent penetration capabilities and antiangiogenic properties aimed at treating retinal neovascularization diseases.

Background: Lindaspio polybranchiata, a member of the Spionidae family, has been reported at the Lingshui Cold Seep, where it formed a dense population around this nascent methane vent. We sequenced and assembled the genome of L. polybranchiata and performed comparative genomic analyses to investigate the genetic basis of adaptation to the deep sea.

Sjögren's syndrome-related dry eye (SSDE) is a severe dry eye subtype characterized by significant immune cell attacks on the lacrimal gland. However, delivering immunosuppressive drugs to the lacrimal glands for SSDE therapy safely and sustainably poses significant challenges in clinical practice. Herein, a ROS-responsive microneedle patch with detachable functionality (CE-MN) is developed to enable straightforward and minimally invasive administration to the lacrimal gland area by penetrating the periocular skin.

Purpose: To investigate changes in fluid reservoir turbidity parameters over time and its influence on visual performance in eyes with ocular surface disorders (OSD) wearing scleral contact lenses (SL).
Methods: Thirteen eyes with OSD were assessed for corrected distance visual acuity, contrast sensitivity (CS) and fluid reservoir turbidity using anterior segment optical coherence tomography at baseline, after 5 min and 0.5, 1, 2, 3 and 4 h of SL wear on day 1 and after 1 month.

Purpose: Corneal alkali burns are severe ocular injuries characterized by intense inflammation, tissue damage, and vision impairment, with current treatments often insufficient in restoring corneal function and clarity. This study aimed to evaluate the therapeutic effects of recombinant thrombomodulin domain 1 (rTMD1) in the treatment of corneal alkali burns, focusing on its impact on inflammation, tissue repair, fibrosis, and neovascularization.
Methods: A murine model of corneal alkali burn was utilized to investigate the therapeutic potential of rTMD1.
