Immunohistochemical methods allow the identification of papillomavirus common antigen within epithelial cell nuclei of most conjonctival papillomas. This result supports the etiological role of papillomaviruses in these benign tumors.

We evaluated 16 patients with malignant melanomas of the choroid (11) or the ciliary body (5) by magnetic resonance imaging (MRI), using a 0.5 T magnet and a surface coil. The tumor was seen in all cases, hyperintense in T1-weighted images, and hypointense in T2-weighted sequences (80%). These images reflected the short T1 and T2 relaxation times caused by the presence of melanin in those tumors. This non-invasive method was superior to computed tomography (70%), and sometimes superior to fundoscopy (2 cases), angiofluorography (3 cases) or echography (1 case). MRI also proved valuable for differentiating uveal melanoma from associated subretinal effusion.
The intraocular penetration of Ciprofloxacin in man: authors have studied the penetration of Ciprofloxacin in the aqueous humor of 30 patients (30 eyes). The concentration in the anterior chamber was on average 0.73 mg/l which is 33% of serum level, from 1.30 hours after a single oral dose of 1000 mg till the 4th hour after this dose. The samples were assessed by a microbiological method. These results are over the minimal inhibitory concentration for many bacterial agents found in endophthalmitis. So this antibiotic may be proposed in the treatment of endophthalmitis. Anyway further investigation is mandatory to assess the safety on efficacy of these antibiotics.
In our daily clinical practice, keratomycosis still remain a challenge for both the ophthalmologist and the laboratory. In this paper simple advices are listed to help us, especially in the topical medical treatment. The emerging role of silver sulfadiazine is pointed out.
