Corneal topographic changes caused by the pterygium are almost reversible after surgical treatment. Successful pterygium surgery significantly reduces topographic astigmatism, SRI, SAI, and corneal flattening. However, precise prediction of these refractive changes is not always accurate.

Cicatricial pemphigoid is an extremely rare condition in children, since only 17 cases have been reported in the English literature, so far. We describe a new case in a 20-month-old boy, who is to our knowledge the youngest patient reported yet. The disorder had begun 10 months before he was referred to our department by mucosal crusted erosions of the oral and nasal cavities and conjunctivae. Cutaneous examination showed buccal erosions with limited mouth opening, entropion of the lower eyelids, trichiasis, cicatricial cornea, synechia of the nasal cavities and hypopigmented lesions of the abdomen. There were no anal or genital lesions. Cicatricial pemphigoid was confirmed by positive direct and indirect immunofluorescence on mucous biopsy. Systemic corticosteroids (2 mg/kg/day), maintained for 12 months, had led to complete healing of lesions. But due to cicatrization, synechia of the nasal cavities and corneal opacities, leading to a dramatic visual loss, have occurred. Dapsone 25 mg/day and topical ocular cyclosporine are now maintained to avoid relapse. Our review of the literature of all cases of CP showed that ocular and to a less degree, vulvar lesions are the most severe ones, due to the serious complications with scar formation.

The expression pattern of VEGF, p53 and ICAM-1 was studied in conjunctiva of diabetic patients with and without retinopathy. All patients underwent a complete ophthalmic examination, including retinal fluorescein angiography. Indirect immunoperoxidase method was performed on 20 eyes of 20 patients with type II diabetes without DR and on 5 eyes of 5 patients with PDR. A control study was performed on 6 normal conjunctiva undertaken during cataract surgery. Immunoreactivity of VEGF, p53 and ICAM-1 was found in epithelial, fibroblast and vascular endothelial cells. For the same duration of diabetes, a strong to moderate or weak immunoreactivity was observed in the conjunctiva of patients without retinopathy. In patients with PDR, the expression was strong for all these proteins. The immunoreactivity was correlated between VEGF, p53 and ICAM-1. In the normal conjunctiva, a weak to negative immunostaining was observed. The presence of these proteins in the conjunctiva of diabetic patients without retinopathy may add new data in the pathogenesis of diabetic retinopathy. Further studies are needed to confirm this hypothesis.
