Corneal abscesses under contact lens

It's represents a severe complication that could lead to vision lost. They are caused by a bad hygiene, a permanent wear of contact lenses and a contamination of boxes. We report a retrospective study of 10 years from January 2003 to december 2013, of patients seen in our hospital for severe corneal abcesses under contact lens. These patients have undergone the same treatement: an initial clinical exam with the assessement of visual acuity, slit lamp exam in order to analyse the corneal infection [superficiel or stromal corneal infection], conjunctival samples or samples within the abcesses, associated to bacterial exam, antibiotherapy in local or general administration, adapted after to bacteriologic results. Corneal abscess represent the major risk wearing contact lenses. Infectious complications have been reported frequently in patients with contact lenses in several series. The corneal abscess is a dramatic complication among patients with contact lenses. A good support is based primarily on early diagnosis and quality of the first treatment

contribution of MRI in malignant choroidal melanoma

Malignant melanoma of the choroid is a rare condition, however it is the most common primary intraocular tumor in adults. The contribution of MRI in choroidal melanoma is considerable, given its specificity for melanin. We report one case of malignant choroidal melanoma. Our case of malignant choroidal melanoma whose ultrasound signs are very suggestive. An MRI signal intensity on Tl and hypo intensity on T2 are obvious, we also found no metastases. Enucleation was performed for the patient, histological analysis confirmed the diagnosis. At the genetic level, melanoma usually presents no recognized character of inheritance. The importance of the degree of pigmentation and growth uveal melanoma varies from one subject to another. It is very important to determine the value of imaging and especially MRI in the diagnosis of choroidal tumors
