Systematic Review on Therapeutic Strategies to Minimize Corneal Stromal Scarring After Injury.

Objectives: To evaluate recent studies on available and experimental therapies in preventing or minimizing corneal stromal scarring after injury.

Methods: We performed an Entrez PubMed literature search using keywords "cornea," "scarring," "haze," "opacity," "ulcer," "treatments," "therapies," "treatment complications," and "pathophysiology" resulting in 390 articles of which 12 were analyzed after filtering, based on English language and publication within 8 years, and curation for relevance by the authors.

Results: The 12 articles selected included four randomized control trials (RCTs) (two were double-blinded placebo-controlled RCTs, one was a prospective partially masked RCT, and one was an open-label RCT), two retrospective observational studies, and six laboratory-based studies including two studies having in vivo and in vitro experiments, one was in vivo study, one was ex vivo study, and the last two were in vitro studies.

Lycium barbarum polysaccharide extracts preserve retinal function and attenuate inner retinal neuronal damage in a mouse model of transient retinal ischaemia.

Background: Retinal ischaemia is a common feature shared by numerous eye diseases. Ischaemic insult leads to retinal dysfunction and neuronal death. Lycium barbarum polysaccharides are well known for eyesight preservation.

Lutein facilitates physiological revascularization in a mouse model of retinopathy of prematurity.

Background: Retinopathy of prematurity is one of the leading causes of childhood blindness worldwide, with vessel growth cessation and vessel loss in phase I followed by neovascularization in phase II. Ischaemia contributes to its pathogenesis, and lutein protects against ischaemia-induced retinal damages. We aimed to investigate the effects of lutein on a murine model of oxygen-induced retinopathy.
