Churg-Strauss syndrome, a small and medium vessel vasculitis, was first described by Churg and Strauss in 1951. It is characterised by the presence of asthma, prominent tissue and blood eosinophilia, systemic vasculitis, and pulmonary and systemic necrotising allergic granulomas. Involvement of the skin, heart and gastrointestinal tract is well documented, but ocular presentation is unusual. We...

Conjunctival melanoma is a rare malignant tumour of the eye. Its diagnosis represents a challenge for general pathologists due to low exposure to ocular biopsies and a broad differential diagnosis. In addition, conjunctival samples are often small and are associated with a high frequency of artefacts due to their processing. Here, we present the first case to date of a traumatic iridial extrusi...

In ocular cicatricial pemphigoid, the binding of circulating antibodies to conjunctiva is believed to initiate an antibody-mediated cytotoxic response that results in inflammation and tissue damage. To develop a model of antibody-mediated conjunctival inflammation, we examined the effect on conjunctiva of local or systemic administration of a murine monoclonal antibody against basement membrane...

A 40-year-old woman presented with ocular discomfort in both eyes that had persisted for several months. Six months ago, she had undergone a bilateral nasal and temporal conjunctivectomy using a bare scleral technique followed by a postoperative application of 0.02% mitomycin C (MMC) to treat her chronic hyperemic conjunctiva for cosmesis. Slit-lamp examination revealed that the patient had bil...

AIM To detect the presence of 8-hydroxydeoxyguanosine enzyme (8-OHdG) in recurrent pterygium and its role on recurrence. METHODS Ninty-two samples were collected of which 55 from primary pterygium, 12 from recurrent and 25 from normal conjunctiva. A cross sectional study was embarked to detect the presence of the 8-OHdG enzyme in primary, recurrent pterygium and the normal conjunctival tissue...

In the 1975-2004 period, 130 cases of pterygium were estimated, 83 males and 47 females, on a small island Rab. Island Rab is located in the north part of the Adriatic sea, which has very high index of sun radiation. Pterygium is usually histopathologically defined as a hyperplasia of conjunctival tissue, elastoid degeneration of subepithelieum and fragmentation of Bowman's membrane. Our histop...

PURPOSE To report the clinicopathologic features of a case of conjunctival synthetic fiber granuloma. CASE REPORT A 6-year-old girl presented with a slow-growing red nodule in the right inferior conjunctival sac with no history of surgery or trauma. Histopathological examination revealed foreign body type granulomatous inflammation around birefringent fibers of variable colors consistent with...

Background and Aim: The purpose of the present study is to provide a basis for use propolis as therapeutic agent allergic conjunctivitis. Methods: effect eye drops on experimental conjunctivitis in rats was investigated. occurred by sensitization challenge egg albumin number scratching, hyperemia, chemosis, vascular permeability histamine content conjunctival tissue tears were assayed. Results:...

A specialized lymphoid tissue in rabbit conjunctiva was studied by various histologic and immunologic techniques and compared with similar structures along other mucosal surfaces. The flattened conjunctival lymphoepithelium overlying the lymphoid follicles was devoid of goblet cells. This lack of goblet cells is characteristic of epithelium overlying similar lymphoid collections in gut and bron...

AIM To determine if beta defensins are expressed in the anterior segment of the eye and to determine the temporal pattern of expression using a real time semiquantitative reverse transcription polymerase chain reaction (RT-PCR). METHODS Ocular tissue (corneal epithelium, conjunctiva, iris, and lens capsule) was collected from 23 patients undergoing surgery. Serial corneal or conjunctival impr...
