A 54-year-old male developed symptomatic scleral buckle exposure 16 years after placement and presented with large conjunctival defects with fibrosed edges. Following surgical removal of the buckle elements, primary conjunctival closure could not be achieved due to significant wound tension despite undermining the conjunctival edges to mobilize the conjunctiva. A dehydrated amniotic membrane graft (Ambio5; IOP Ophthalmics, Costa Mesa, CA) was placed on the scleral bed and secured in place with fibrin sealant (TISSEEL; Baxter International, Westlake Village, CA)...

INTRODUCTION: Contact lens wearers of Asian descent may be predisposed to experience microtrauma of the ocular surface as a result a thinner post-lens tear film and higher eyelid tension, and these effects would be anticipated to be most marked in an older population. The objective of this study was to quantify the mechanical effects of the study contact lenses on the ocular surface in a population of presbyopic contact lens wearers of Asian descent. METHODS: Twenty established presbyopic contact lens wearers (hydrogel n=5, none habitual wearers of etafilcon A lenses; silicone hydrogel n=15) of Asian descent were refitted with etafilcon A multifocal daily disposable contact lenses (1-DAY ACUVUE MOIST MULTIFOCAL) for a period of 1 month of daily lens wear...

Amyloidosis of the eyelid is uncommon and is typically associated with systemic associations. In contrast, amyloidosis of the conjunctiva is often localised with no other associations. We present a rare case of a 92-year-old gentleman with both cutaneous lid lesions and conjunctival amyloid with no systemic involvement. Biopsy demonstrated the hallmarks of amyloid and treatment has remained conservative. He remains at the department to be monitored for secondary glaucoma.

Purpose: The autoimmune blistering skin disease pemphigus vulgaris (PV) is caused by autoantibodies against desmosomal adhesion molecules. Patients may suffer conjunctival involvement, yet the underlying mechanisms are largely unclear. We characterized human and murine conjunctiva with respect to the PV autoantigens, and evaluated the effects and mechanisms of PV autoantibodies applied to human conjunctiva ex vivo. Methods: We obtained human conjunctiva specimens from surgical explants and established a short-term culture model to study the alterations induced by antibody fractions of PV patients (PV-IgG)...

PURPOSE: There are very few studies that describe the technique and results of double-headed pterygium removal and most of these have recurrence rates higher than those described for single pterygium removal. P.E.R.F.E.C.T for PTERYGIUM has a very low recurrence rate, and this study describes the recurrence rate and cosmesis when used on double-headed pterygia. METHODS: A prospective intervention series was performed on 20 eyes with a follow-up of 1 year or more with examination for recurrence and cosmetic appearance...

Limbal stem cell deficiency is predominantly caused by severe eye burns resulting in a decreased or a complete ablation of the regenerative potential of these stem cells. The inability to reconstruct the corneal epithelium further leads conjunctivalization of the gimbal-epithelial barrier. These abnormalities collectively result in the progressive opacification of the cornea responsible for blindness that is driven by chronic corneal ulceration and neovascularization. The underlying pathology of the cornea affects the homeostasis of the neighboring conjunctiva, eyelids, and tear film...

Pterygium is a triangular shaped ocular fibrous surface lesion growing from conjunctiva towards central cornea, causing ocular irritation, astigmatism, and visual disturbance. The condition is characterized by epithelial proliferation, fibrovascular growth, chronic inflammation, and prominent extracellular matrix remodeling. Studies have suggested that aberrant extracellular proteins secreted by fibroblasts lead to abnormal matrix production and tissue invasion contributing to the development of the disease...

BACKGROUND: Cannabis is the most widely used illicit drug in the United States and Europe. In recent years, a range of new substances with cannabis-like effects - known as synthetic cannabinoids (SCs) - have suddenly burst on the drug scene. However, there is limited information about the clinical hazards linked to the use of these emerging substances. This review summarizes the literature to date relating the health effects of SCs. METHOD: A systematic literature review of original case studies was performed using 'Pubmed' and the 'Web of Science' (January, 1980 - July, 2015)...

OBJECTIVE: To determine modifiable risk factors of ocular surface squamous neoplasia (OSSN) in Kenya using disease-free controls. METHODS: Adults with conjunctival lesions were recruited at four eye care centres in Kenya and underwent excision biopsy. An equal number of controls having surgery for conditions not affecting the conjunctiva and unrelated to ultraviolet light were group-matched to cases by age group, sex and eye care centre. Associations of risk factors with OSSN were evaluated using multivariable logistic regression to estimate odds ratios (ORs) and 95% confidence intervals (95%CI)...
