Regeneration of the corneal surface after an epithelial insult involves division, migration, and maturation of a specialized group of stem cells located in the limbus. Several insults, both intrinsic and extrinsic, can precipitate destruction of the delicate microenvironment of these cells, resulting in limbal stem cell deficiency (LSCD). In such cases, reepithelialization fails and conjunctiva...

CLINICAL CASE A 71-year-old woman presented with a leaking bleb after a combined phacotrabeculectomy performed 13 years ago. To construct a new filtering bleb, the necrotic area was fully excised. The amniotic membrane was inserted over the scleral flap underneath healthy conjunctiva edges. A conjunctiva-Tenon autograft from the contralateral eye was sutured and was sealed with fibrin adhesive....

PURPOSE To demonstrate the long term of follow-up of the recurrence rate after conjunctival autograft for pterygium surgery. METHODS A total of 112 patients operated for pterygium with conjunctival autografts and with more than one year follow-up were registered. Patients were called for voluntary examinations of their respective ocular surface statuses. Completing the study was only possible...

PURPOSE To describe the clinical and histopathological features of a 61-year-old male with a history of eczema, asthma and schizophrenia on long-term chlorpromazine medication, who developed a unilateral limbal tumour in association with bilateral melanosis. PROCEDURES The patient was referred for a routine cataract assessment, and an incidental pink gelatinous limbal lesion was detected on t...

A 15-year-old Asian male, with a history of skin allergy and asthma, presented complaints itching, photophobia, redness in both eyes for the last 10 years. His right eye showed upper lid papillae, perilimbal conjunctival pigmentation, gelatinous limbal hyperplasia temporal quadrant (Fig A), pseudogerontoxon involving nasal cornea B). The superior limbus multiple raised, circumscribed, transpare...

purpose: to compare the efficacy and safety of topical mitomycin- c 0.01% versus dexamethazone phosphate 0.1% in patients with refractory vernal keratoconjunctivitis (vkc). methods: in this double blind randomized clinical trial, patients with refractory vkc were randomly assigned to treatment with topical mitomycin-c 0.01% eye drops (n=27) or dexamethazone phosphate 0.1% (n=27), four times dai...

PURPOSE To analyze conjunctival cytological features 1 month after pterygium excision using limbo-conjunctival autograft (LCA) with and without intraoperative mitomycin C and to assess tissue short-term evolution in both situations. METHODS Fifty-nine primary nasal pterygia from 59 patients were excised with LCA. Twenty-nine were treated with intraoperative mitomycin C 0.02% (MMC+) and 30 wer...
