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.

This paper presents the findings in a series of 30 patients with blepharochalasis, including the age of onset, sex, predisposing factors, symptoms and signs, frequency and duration of attacks, and length of the history. There were 16 bilateral and 14 unilateral cases. The condition can be divided into an active (early) and a quiescent (late) stage. The active stage is further subdivided into intumescent (hypertrophic) and atrophic forms. The sequelae included excess thin skin, fat herniation, lacrimal gland prolapse, ptosis, blepharophimosis, pseudoepicanthic fold, proptosis, conjunctival injection and cysts, entropion, and ectorpion. Surgery primarily involved blepharoplasty, ptosis correction, and lateral canthal reattachment alone or in combination. The pathology showed a variable picture of epithelial atrophy, vasculitis, and loss of elastic fibers, which did not greatly help to differentiate blepharochalasis from angioedema, lymphedema, dermatochalasis, tumors and infiltrations, and floppy lid syndromes. Blepharochalasis is probably a localized angioedema. The diagnosis depends on the clinical features of intermittent attacks of localized swelling affecting one or more eyelids associated with thinning of the skin giving either an intumescent (hypertrophic) or atrophic appearance in the active stage of the condition and progressing to atrophic changes in the quiescent (late) stage.

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.
