Intense Pulsed Light in the Treatment of Dry Eye and Meibomian Gland Dysfunction in Patients With Chronic Stevens-Johnson Syndrome and Toxic Epidermal Necrolysis.
Cornea
January 2025
Department of Ophthalmology and Visual Sciences, Escola Paulista de Medicina, Universidade Federal de São Paulo, São Paulo, SP, Brazil.
Purpose: To evaluate the efficacy and safety of intense pulsed light (IPL) combined with meibomian gland expression (MGX) for the treatment of dry eye disease and meibomian gland dysfunction associated with chronic Stevens-Johnson syndrome and toxic epidermal necrolysis.
Methods: This prospective noncomparative interventional study included 29 patients (58 eyes) who underwent 3 sessions of IPL and MGX at 2-week intervals. Subjective symptoms (ocular surface disease index score) and objective dry eye tests: matrix metalloproteinase 9, tear meniscus height, bulbar redness score, tear film lipid layer thickness (LLT), Schirmer I test, conjunctival and corneal staining, meibomian gland loss, MGX score [meibomian gland score (MGS)], and tear break-up time were assessed at the baseline and after 4, 8, and 12 weeks.
The Effect of Autologous Serum Tears 50% on the Ocular Surface of Patients With Severe Dry Eye Disease due to Sjogren Syndrome: A Prospective, Double-Blind, Randomized, Controlled, Contralateral Eye Study.
Cornea
January 2025
Department of Ophthalmology, University of Cyprus Medical School, Nicosia, Cyprus.
Purpose: To assess the impact of autologous serum (AS) tears at a 50% concentration on the ocular surface of patients with refractory dry eye disease (DED) because of Sjogren syndrome.
Methods: Twenty eyes of ten patients with severe immune-mediated DED were contralaterally randomized to receive either AS tears 50% or artificial tears between June 2021 and May 2023. Changes in tear stability, ocular surface staining, and in the morphology of the corneal sub-basal nerves were evaluated before treatment and at 1, 2, and 3 months after treatment using objective tests for DED and confocal microscopy.
Low-temperature vacuum evaporation as a novel dehydration process for the long-term preservation of transplantable human corneal tissue.

Globally there is a shortage of available donor corneas with only 1 cornea available for every 70 needed. A large limitation to corneal transplant surgery is access to quality donor tissue due to inadequate eye donation services and infrastructure in many countries, compounded by the fact that there are few available long-term storage solutions for effectively preserving spare donor corneas collected in countries with a surplus. In this study, we describe a novel technology termed low-temperature vacuum evaporation (LTVE) that can effectively dry-preserve surplus donor corneal tissue, allowing it to be stored for approximately 5 years, shipped at room temperature, and stored on hospital shelves before rehydration prior to ophthalmic surgery.

Decellularization is the process of obtaining acellular tissues with low immunogenic cellular components from animals or plants while maximizing the retention of the native extracellular matrix structure, mechanical integrity and bioactivity. The decellularized tissue obtained through the tissue decellularization technique retains the structure and bioactive components of its native tissue; it not only exhibits comparatively strong mechanical properties, low immunogenicity and good biocompatibility but also stimulates neovascularization at the implantation site and regulates the polarization process of recruited macrophages, thereby promoting the regeneration of damaged tissue. Consequently, many commercial products have been developed as promising therapeutic strategies for the treatment of different tissue defects and lesions, such as wounds, dura, bone and cartilage defects, nerve injuries, myocardial infarction, urethral strictures, corneal blindness and other orthopedic applications.

Refractive error (RE) and myopia are complex polygenic conditions with the majority of genome-wide associated genetic variants in non-exonic regions. Given this, and the onset during childhood, gene-regulation is expected to play an important role in its pathogenesis. This prompted us to explore beyond traditional gene finding approaches.
