OBJECTIVES To clinically evaluate topical mitomycin chemotherapy in patients with diffuse, multifocal, or recurrent primary acquired melanosis with atypia and/or conjunctival malignant melanoma and to histopathologically study ocular tissue samples obtained before and after treatment. METHODS Chemotherapy with topical mitomycin, 0.04% 4 times daily, was administered for 28 days as the primary...

purpose: to investigate the efficacy of limbal-conjunctival autografting technique in patients with primary pterygium methods: fifteen eyes of 15 patients with primary pterygium underwent surgery for the removal of pterygium with limbal-conjunctival autograft. after the pterygium excision, the limbal portion of the graft was oriented and sutured to the limbus at the recipient bed with the epith...

Conjunctival melanoma is a rare and potentially deadly tumor. Therefore, adequate oncological resection essential, commonly leading to total orbital exenteration, which causes patients' extensive functional cosmetic impairment. As result, it essential reconstruct the region post-exenteration obliterate cavity, provide pliable cutaneous covering, restore stable vascularized tissue that can withs...

PURPOSE Preservation of the ocular surface barrier requires complex control of epithelial cell proliferation and inflammation mechanisms. The endocannabinoid system may be regulating these processes. Therefore, the authors explored the presence and properties of cannabinoid receptors (CB1 and CB2) in conjunctival epithelial cells. METHODS The authors used immunohistochemistry to detect CB1 an...

Trachoma is the most common infectious cause of blindness and a major public health problem in many developing countries. It is caused by recurrent ocular infection with Chlamydia trachomatis in childhood, with conjunctival scarring seen later in life. The pathogenesis of trachomatous scarring, however, is poorly understood, and this study was carried out to investigate the immunofibrogenic cor...

OBJECTIVES To describe the clinical features of a conjunctival nevus and to evaluate the lesion for changes in color and size over time. DESIGN Retrospective, observational, noncomparative case series. PARTICIPANTS Four hundred ten consecutive patients with conjunctival nevi. MAIN OUTCOME MEASURES The 2 main outcome measures were changes in tumor color and size. RESULTS Of the 410 patie...

PURPOSE Ocular surface squamous neoplasia (OSSN) is an uncommon tumor of the corneal and conjunctival epithelium associated with risk of permanent visual impairment. The purposes of this study were to (1) identify and localize potential mediators in tissue from patients with OSSN and (2) culture human dysplastic conjunctival epithelial cells (DCECs) to determine their responsiveness to ultravio...

Melanoma of the conjunctiva is a rare tumor with incidence from 0,03 to 0,08 cases per 100000 white population. Metastatic malignant melanoma represents approximately 5% of all secondary malignant lung tumors. We report the unexpected discovery of a pulmonary and pleural metastasis from a conjunctival melanoma in a young subject.

background: normal bacterial flora of the conjunctiva, which inhibits growth of opportunistic organisms, has an important role in the prevention of ocular infections. if resident flora is inhibited by disease or long-term application of antibiotics, opportunistic pathogens overgrow, leading to disease. objectives: the aim of this study was to investigate the effects of ophthalmic chloramphenico...
