Persistent corneal erosions may be primary or secondary to a variety of ocular diseases such as KCS, infection, or adnexal disease. Primary corneal diseases that may result in nonhealing erosions include corneal EBMD and endothelial dystrophy or degeneration. The challenge that the practitioner faces is to differentiate between them and to apply the appropriate treatment. A variety of medical and surgical therapies are at the disposal of the practitioner. These include debridement, contact lens placement, superficial keratectomy, punctate keratotomy, hyperosmotic solutions, and several new drug modalities such as epidermal growth factor, fibronectin, and aprotinin.

We developed and tested ocular inserts containing epidermal growth factor (EGF) for a causal treatment of keratoconjunctivitis sicca (KCS). The inserts, consisting of different alginates with hydroxyethylcellulose (HEC) as a lubricant and release modifier, released EGF over time periods ranging from a few hours up to several days. The stability of EGF was high, having a protein half-life of approximately 548 days. A clinical pilot study suggests an amelioration of both the main symptoms and the objective criteria: tear film break-up (BUT) time and lissamine green score. Our results show that EGF treatment of KCS is highly promising.

Conventional treatment of dry eye mainly consists of the use of preservative-free artificial eye drops and punctal occlusion. None of the commercially available artificial tear preparations include essential tear components such as epidermal growth factor, hepatocyte growth factor, fibronectin, neurotrophic growth factor, and vitamin A-all of which have been shown to play important roles in the maintenance of a healthy ocular surface epithelial milieu. We reported previously that autologous serum (AS) eye drops contain these essential factors and that AS eye drops are beneficial in the treatment of ocular surface diseases such as persistent epithelial defects, superior limbic keratoconjunctivitis, keratoconjunctivitis sicca, and neurotrophic keratopathy. However, there is some controversy regarding the efficacy of AS treatment. We demonstrated that this modality is more effective than artificial tears in a randomized control study. In in vivo and in vitro experiments, AS eye drops showed marked suppression of apoptosis in the conjunctival and corneal epithelium. Albumin, the major protein in serum, improved ocular surface damage in vivo and rescued apoptosis after serum deprivation in vitro. The biological background of AS eye drops and previous clinical studies of these medications for the treatment of dry eye are discussed.

Sjogren's Syndrome (SS) is a chronic, female overwhelming fundamental issue of an immune system rheumatic sickness that influences the whole body. It is described by lymphocytic invasion of the exocrine viz. salivary and lacrimal glands and by surprising B-cell hyperactivity. Keratoconjunctivitis sicca (dry eye) and Stomatitis sicca (oral dryness) are the primary visual appearances of SS. The primary SS is recognized from secondary SS which happens as a piece of other immune system maladies. The secondary SS exists together particularly with fundamental lupus erythematosus (15- 36%), rheumatoid joint inflammation (20- 32%) and also restricted and progressive systemic sclerosis (11- 24%), less as often as possible with different sclerosis and immune system hepatitis and thyreoiditis. We assess changes in salivary epidermal growth factor (EGF) intensity and estimate the relationship between salivary EGF levels and the seriousness of intraoral symptoms in SS individuals. The outcomes demonstrated that the salivary EGF levels diminished with the movement of SS, and this crumbling in salivation quality and additionally, hyposalivation could imagine a vital constituent in the pathogenesis of refractory intraoral indication in SS suffering patients. A strong relationship between particular alleles of the MHC and SS improvement has been recommended. The primary hereditary examination on SS revealed a relationship amongst SS and HLA-DR3 in SS population. Subsequent reports featured the relationship amongst SS and the HLA-D locus, with a diverse distribution between primary SS and secondary SS. The motivation behind this manuscript is to give a concise survey on the molecular mechanism, effects of infectious agents and genetic factors in the etiology of Sjogren's Syndrome. Such effects are discussed independently.
