The Hughes' tarsoconjunctival flap technique has proved to be a reliable operative procedure for the treatment of large lower-lid defects for more than 55 years. The Hughes' procedure has maintained its importance despite the development of numerous other operations, two reasons for this being that there have now been several modifications to this technique and that the lids do not have to be closed as long. To help the surgeon avoid and eliminate problems and errors in the operative technique we provide details and some useful tricks we have learned over the years while treating over 50 patients. The causes, prophylaxis, and correction of postoperative complications are described for the following: lowering the lid margin; thinning of the lid in the area of the tarsal transposition; lymph edema of the transplant; lid margin defects, and dehiscence of the wound; corneal epithelial defects; trichiasis caused by lanugo hair; keratinization of the lid margin; ectropion of the conjunctiva; retraction of the upper lid, and entropion of the upper lid. If these details are taken into consideration, the Hughes' procedure is a simple operative technique that is free of serious complications and gives good results in the reconstruction of the lower lid.

Trachoma is a leading cause of preventable blindness worldwide. The disease is caused by an intracellular epithelial gram-negative bacterium, Chlamydia trachomatis. The presence of children, overcrowding, and the lack of water in the household are factors that predispose to the transmission of the disease. The disease may remain asymptomatic but some patients many complain of redness, irritation, and ocular discharge. The principal initial clinical manifestation is a follicular conjunctivitis that may lead to conjunctival scarring, entropion, trichiasis, corneal thinning, and ulceration. Some patients develop corneal scars that lead to loss of vision. Despite the remarkable progress in our understanding of Chlamydial infections, the basic mechanisms involved in tissue damage and scarring remain to be elucidated. There are several effective therapeutic modalities for trachoma. Azithromycin oral single dose was found to be safe and effective in children with active trachoma. Conjunctival biopsy specimens obtained from adult patients receiving a single oral dose of azithromycin showed sustained high levels of azithromycin (above MIC of chlamydia) for up to 2 weeks after intake. These prolonged high levels of azithromycin in the conjunctival tissue following a single oral dose makes the drug suitable for the treatment of endemic trachoma.

Two brothers with very similar phenotypes involving trichiasis (misdirected lashes), entropion with corneal abrasions, strabismus, progressive thinning of the scalp hair, sensorineural hearing impairment, mild learning difficulties, and inguinal hernias are described. They have similar, distinctive facial features with deep-set eyes, a high nasal bridge and a short philtrum. Both brothers are carriers of a maternally inherited apparently balanced translocation of chromosomes 11 and 18: 46,XY, t(11;18)(p13;q21)mat. However, this is thought to be coincidental, since their younger brother also carries this translocation and is phenotypically normal. Although they have many features that are found in the ectodermal dysplasia syndromes, their combination of features is distinct and has to our knowledge not been previously reported.

Linear scleroderma en coup de sabre with ophthalmic findings has been previously described in the literature on numerous occasions. A 57-year-old woman presented with focal trichiasis secondary to tarsal thinning, adjacent to a linear brow and forehead deformity consistent with linear scleroderma en coup de sabre. Cases of linear scleroderma en coup de sabre involving the eyelids have been reported, most often with madarosis, ptosis, or skin atrophy; however, to the authors' knowledge, this is the first reported case of linear scleroderma associated with trichiasis and involvement of the deeper eyelid tissues, particularly the tarsus.
