Conjunctival goblet cells (GCs) were quantitated to establish baseline values for density and distribution of these cells in healthy canine eyes. From each of 18 sites, tissue was collected, sectioned at 2 micron, and stained with periodic acid Schiff stain. Within each sampling site, 500 epithelial cells (GCs, squamous, polygonal, and basal epithelial cells) were counted and the ratio of GCs t...
Goblet cell counts have been used to evaluate the suitability of conjunctiva as a source of ocular surface epithelial cells. However, since tear mucin content can be determined without tissue excision, it seemed that the concentration of those compounds might be a useful indicator of conjunctival vitality. To test the extent to which aqueous tear composition reflects conjunctival goblet cell fr...
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...
PURPOSE Several genes that are associated with protection from or susceptibility to trachomatous trichiasis (TT) have been identified through genetic association studies. Yet there have been few studies in which gene expression profiles were assessed in TT cases and disease-free controls. The purpose was to identify genes that are differentially expressed in the upper tarsal conjunctiva of subj...
BACKGROUND Amyloidosis is a systemic disorder that results from the tissue deposition of various proteins with distinctive morphological characteristics. Conjunctival amyloidosis is a rare variant which is generally localized and not associated with systemic involvement. CASE REPORT We present here a case of 47-year-old female patient with right eyelid swelling that progressed over a 12 year ...
Purpose: To evaluate the clinical results of patients treated by amniotic membrane transplantation (AMT) following excision of conjunctival and limbal tumors. Methods: A total of 14 eyes of 14 patients who underwent AMT after total lesion-free tumor excision and perilesional cryotherapy were evaluated. Results: The excised tumors comprised 7 conjunctival intraepithelial neoplasia, 5 conjunc...
Extra nodal marginal zone B-cell lymphoma (EMZL) of the conjunctiva typically arises in the marginal zone of mucosa-associated lymphoid tissue. The pathogenesis of conjunctival EMZL remains unknown. We describe an unusual case of EMZL arising from reactive lymphoid hyperplasia (RLH) of the conjunctiva. A 35-year-old woman had fleshy salmon-pink conjunctival tumors in both eyes, oculus uterque (...
PURPOSE To evaluate the histopathologic changes in the conjunctiva of patients with conjunctivochalasis (CCh) compared to age-matched controls. METHODS This cross-sectional, controlled study included 27 eyes of 27 patients with CCh and 16 eyes of 16 age-matched controls. A biopsy of the bulbar conjunctiva was performed along the temporal lower lid margin before cataract surgery in both groups...
PURPOSE To examine the distribution of human heat shock proteins (HSPs) HSP90, inducible HSP70 (iHSP70), constitutive and inducible HSP70 (cHSP70), HSP65, and human HSP27 in conjunctival biopsy specimens of ocular cicatricial pemphigoid (OCP), atopic keratoconjunctivitis, and healthy persons with cataract. METHODS Using an immunoperoxidase technique, conjunctival biopsy specimens from ten pat...
To the Editors of THE BRITISH JOURNAL OF OPHTHALMOLOGY. SIRs,-I have read with interest Mr. Affieck Greeves' letter in the correspondence section of the July number criticising the corneoscleral suture in cataract extraction. (See Brit. Ji. of Ophthal., May, 1938.) I agree with his preference for a conjunctival stitch on the grounds that a more liberal conjunctival flap is obtainable by this me...
