Purpose: To assess the use of ultra-high-resolution (UHR) optical coherence tomography (OCT) in the diagnosis of ocular surface lesions.
Design: Prospective, noncomparative, interventional case series.
Participants: Fifty-four eyes of 53 consecutive patients with biopsy-proven ocular surface lesions: 8 primary acquired melanosis lesions, 5 amelanotic melanoma lesions, 2 nevi, 19 ocular surface squamous neoplasia lesions, 1 histiocytosis lesion, 6 conjunctival lymphoma lesions, 2 conjunctival amyloidosis lesions, and 11 pterygia lesions.
Intervention: Ultra-high-resolution OCT imaging of the ocular surface lesions.
Main Outcome Measures: Clinical course and photographs, UHR OCT image, and histopathologic findings.
Results: Ultra-high-resolution OCT images of all examined ocular surface lesions showed close correlation with the obtained histopathologic specimens. When clinical differential diagnosis of ocular surface lesions was broad, UHR OCT images provided optical signs indicating a more specific diagnosis and management. In cases of amelanotic melanoma, conjunctival amyloidosis, and primary histiocytosis and in 1 case of ocular surface squamous neoplasia, UHR OCT was instrumental in guiding the diagnosis. In those cases, UHR OCT suggested that the presumed clinical diagnosis was incorrect and favored a diagnosis that later was confirmed by histopathologic examination.
Conclusions: Correlations between UHR OCT and histopathologic findings confirm that UHR OCT is an adjunctive diagnostic method that can provide a noninvasive means to help guide diagnosis and management of ocular surface lesions.

Background: While prosthesis-associated malignancies have been acknowledged, awareness among surgeons and patients in the ophthalmologic field remains limited, despite the frequent occurrence of prosthesis-related surgeries. We aim to address this gap through a scoping review of malignancies following ophthalmologic surgeries involving various foreign device/prosthesis/implants.
Methods: Following PRISMA guidelines, we conducted a review using PubMed and Embase for studies on cancer and ophthalmic prostheses/implants.

Epidemic keratoconjunctivitis (EKC) is one of the most severe clinical manifestations of human adenovirus ocular surface infection, which may lead to the formation of subepithelial infiltrates (SEIs) in the anterior corneal stroma in 20-50 % of cases. SEIs may be asymptomatic or give rise to corneal aberrations and visual impairment for months or years after acute infection, despite treatments. Here, we describe the ultrastructural and immunophenotypic features of the anterior corneal stroma of a patient who underwent superficial anterior lamellar keratoplasty (SALK) surgery to remove corneal opacities related to clinically significant and steroid-unresponsive, long-lasting SEIs after adenoviral EKC.

Glaucoma, a leading cause of blindness, demands innovative and effective treatments that surpass the limitations of current drug and surgical interventions to lower intraocular pressure. This study describes the generation of cell-repellent hydrogel patches, their deposition on the ocular surface, and a photoinduced chemical binding between the patches and the collagens of the eye. The hydrophilic and protein-repellent hydrogel patch is composed of a copolymer made from dimethylacrylamide and a comonomer unit with anthraquinone moieties.

Purpose: To assess the relationship between quality of life (QoL) and ocular surface health within a Finnish population-based cohort.
Methods: A cross-sectional study involved 601 individuals born between the years 1933-1956. Ocular surface health and dry eye disease (DED) were clinically evaluated using several diagnostic tests.

The ocular surface ectoderm (OSE) is essential for the development of the ocular surface, yet the molecular mechanisms driving its differentiation are not fully understood. In this study, we used single-cell transcriptomic analysis to explore the dynamic cellular trajectories and regulatory networks during the differentiation of embryonic stem cells (ESCs) into the OSE lineage. We identified nine distinct cell subpopulations undergoing differentiation along three main developmental branches: neural crest, neuroectodermal, and surface ectodermal lineages.
