BACKGROUND: The use of autologous platelet-rich plasma (PRP) and plasma rich in growth factors (PRGF) has been proposed for the treatment of several acute and chronic syndromes, such as corneal epithelial defects and dry eye syndrome, gum bleeding during oral surgery, and in orthopaedic surgery. We hypothesized that PRGF, rather than PRP, could be more effective because of its intrinsic characteristics in promoting the healing of intestinal anastomosis. The purpose of the present study was to evaluate and compare the effects of PRP and PRGF on various parameters of anastomotic healing in a swine model...

In recent decades infrared thermography (IR) has allowed accurate and quantitative measurements of the ocular surface temperature (OST), applying a non-invasive procedure. The objective of this work was to develop a procedure based on IR, which allows characterizing the cooling of the ocular surface of patients suffering from dry eye syndrome, and distinguishing among patients suffering from aqueous deficient dry eye (ADDE) and evaporative dry eyes (EDE). Approach: All patients examined (34F/4M, 23-84 years) were divided into two groups according to their Schirmer I result (≤7 mm for ADDE and >7 mm for EDE), and the OST was recorded for 7 s at 30Hz...

Sjögren's syndrome (SS) is a systemic autoimmune disease characterized by severe inflammation of exocrine glands such as the salivary and lacrimal glands. When it affects the lacrimal glands, many patients experience keratoconjunctivitis due to severely dry eyes. This study investigated the pathological and immunological characteristics of ocular lesions in a mouse model of SS. Corneal epithelial injury and hyperplasia were confirmed pathologically. The number of conjunctival mucin-producing goblet cells was significantly decreased in the SS model mice compared with control mice...

In severe ocular surface disease with limbal stem cell deficiency associated with severe dry eye, penetrating keratoplasty is likely to fail. In these cases, and provided the posterior segment is normal, keratoprosthesis surgery (KPro) can achieve visual rehabilitation. In KPros with an autologous biological haptic, a bone-tooth-complex (osteo-odonto-keratoprothesis, OOKPro) or a piece of tibial cortex (tibia-keratoprosthesis, TKPro) is used to carry a PMMA cylinder. This construct can successfully be implanted even in severely dry eyes and in those with autoimmune disease, in which other KPro designs frequently fail...
