: This study investigates the feasibility of implementing telescreening for retinopathy of prematurity (ROP) using the ICON GO widefield camera operated by a non-physician healthcare professional (NPHP). We hypothesized that images captured by an NPHP are adequate to evaluate ROP changes without further examinations. Secondly, the level of agreement between independent ROP graders were evaluated based on the fundus photographs.

Purpose: The aim of the study was to describe the temporal changes in causes and prevalence of childhood visual impairment in Denmark based on the National Danish Registry of Children with Visual Impairment (NDRCVI).

Methods: Annual reports on the NDRCVI since its establishment in 1979 were reviewed and data on the number of registered children and the causes for registration with a visual impairment were evaluated.

Results: The average annual incidence of childhood visual impairment in Denmark is 2.

Vernal keratoconjunctivitis (VKC) is a rare yet severe form of allergic conjunctivitis predominantly affecting children, mainly boys, with a global prevalence and a higher incidence in certain geographical regions. The disease is characterized by seasonal exacerbations. VKC presents with ocular surface inflammation leading to various distressing symptoms such as itching, redness, mucous discharge, and pain.

Purpose: This double-blinded randomized clinical trial aimed to evaluate the efficacy of injecting allogeneic adipose-derived mesenchymal stem cells (ASCs) into the lacrimal gland (LG) for the treatment of dry eye disease (DED) secondary to Sjögren's syndrome (SS).

Methods: Fifty-four participants with severe DED secondary to SS were included and allocated to either ASCs (n = 20), vehicle (n = 20), or a non-randomized observation group (n = 14). The intervention groups received a single injection of either ASCs or an active comparator (vehicle, Cryostor® CS10) into the LG in one eye, while the observation group received lubricating eye drops only.

To develop a method of injecting a volume up to 50% of the lacrimal gland (LG) volume while minimizing patient discomfort and maximizing accurate drug delivery. Herein we describe a series of ultrasound (US)-guided transcutaneous injections in the LG and discuss the safety and feasibility of this technique. Ultrasonography was performed in 40 patients with aqueous deficient dry eye disease using a GE Logic E10 (Milwaukee, Wisconsin, USA) US machine with a 6-24 MHz transducer.

Purpose: To evaluate the safety and feasibility of injecting allogeneic adipose-derived mesenchymal stem cells (ASCs) into the lacrimal gland (LG) as a treatment of aqueous deficient dry eye disease (ADDE).

Methods: In this open-label, 5-visit clinical trial (baseline, treatment and weeks 1, 4 and 16) seven subjects with ADDE received one transconjunctival injection of allogeneic ASCs into the LG in one eye. The ASC product contained 22 million ASCs/ml and the injected volume was maximally 50% of the LG volume as determined on magnetic resonance imaging (MRI).

Herein, we wanted to explore the molecular landscape of mucosal melanoma from different sites and identify potential molecular targets for future therapy. Mucosal melanomas (N = 40) from different sites (conjunctiva, sinonasal cavity, rectum, and vagina) were investigated. Targeted next-generation sequencing along with Nanostring gene expression profiling was performed.

Objective: To describe the clinicopathological and genomic features of nine patients with primary and secondary orbital/ocular manifestations of leukaemia.

Methods: All orbital/ocular leukaemic specimens from 1980 to 2009 were collected from the Danish Register of Pathology. In six cases, medical records and formalin-fixed, paraffin-embedded blocks were available.

This study aimed to investigate the microRNA (miRNA) profile in primary tumors from conjunctival melanoma with and without subsequent metastatic spread along with their coupled distant metastases to identify miRNAs likely to be involved in metastatic progression. This observational study included 13 patients with metastatic conjunctival melanoma (follow-up: 1-39 years) treated at a Danish referral center. Twenty-five patients with nonmetastatic conjunctival melanoma (follow-up: 5-17 years) were included for comparison.

Relatively little is known about the genetic aberrations of conjunctival melanomas (CoM) and their correlation with clinical and histomorphological features as well as prognosis. The aim of this large collaborative multicenter study was to determine potential key biomarkers for metastatic risk and any druggable targets for high metastatic risk CoM. Using Affymetrix single nucleotide polymorphism genotyping arrays on 59 CoM, we detected frequent amplifications on chromosome (chr) 6p and deletions on 7q, and characterized mutation-specific copy number alterations.

Purpose: Conjunctival melanoma (CM) is a rare disease associated with considerable mortality. As opposed to cutaneous melanoma, the epigenetic mechanisms involved in the development of CM and other mucosal melanomas (MMs) are unclear. The purpose of this study was to identify tumor-specific and prognostic microRNA (miRNA) in CM and to compare the miRNA profile with that of MM.

Conjunctival malignant melanoma is a rare disease associated with considerable mortality. Most published data have been based on case reports or series of referred patients. In addition, very little is known about the genetic and epigenetic profile of conjunctival melanoma and the resemblance to uveal, cutaneous and mucosal melanoma.

Purpose: To investigate incidence, clinicopathological features and prognosis of BRAF-mutated conjunctival melanoma in Denmark. Furthermore, to determine BRAF mutations in paired premalignant lesions and evaluate immunohistochemical BRAF V600E oncoprotein detection.

Methods: Data from 139 patients with conjunctival melanoma (1960-2012) were collected.

Importance: Large studies investigating clinical presentation and treatment in primary conjunctival melanoma (CM) are rare. Clinicopathological characteristics of BRAF-mutated CM have not been studied thoroughly.

Objectives: To determine the associations of clinicopathological tumor features and treatment with local recurrence, metastasis, and mortality and to determine the association of BRAF mutations with these features.

Article Synopsis
  • - This study aimed to explore how microRNA expression and chromosomal changes relate to metastasis and survival outcomes in patients with uveal melanoma (UM), analyzing data from 36 patients.
  • - Key findings indicated that larger tumor size, extraocular extension, and specific chromosomal changes (loss of chromosome 3 and gain of chromosome 8q) were significantly linked to increased risk of metastasis and poorer survival, while TNM staging also correlated strongly with survival rates.
  • - Despite the profiling of microRNA expression, the study found no direct association between microRNA levels and metastasis or survival, emphasizing that chromosomal changes are more reliable predictors in UM outcomes.
