After cataract surgery with an IOL implantation, both vertical and horizontal coma, as well as spherical aberration, were of higher value than in normal eyes. The compensation effect for corneal aberrations of the natural lens is absent in the IOL and explains these findings. The corneal aberrations in pseudophakic eyes reflect better the optical quality of the total eye than the phakic eyes. Nevertheless, the missing correlation in some specific aberrations, such as C8 and C10, shows the inability of corneal topography to provide suitable information on the optical quality of the total eye after cataract surgery. Thus, both corneal and total wavefront measurements are relevant for the assessment of outcomes after cataract surgery.

To report a case of unilateral varicella zoster virus (VZV) retinal vasculitis aspect in an immunocompetent child without systemic infection. Clinically, no signs of retinal necrosis or frosted branch vasculitis were present. This is an observational case report. Quantitative PCR was performed on the aqueous humor (AH) using primers specific for herpes virus (cytomegalovirus, Epstein-Barr virus, herpes simplex virus 1-2, and VZV). The patient was treated with intravenous acyclovir, intravitreous ganciclovir, and oral valacyclovir. A positive quantitative PCR result was found for VZV DNA (1.72 x 10(6) viral copies/ml) in the AH. After 6 months, PCR of the AH was negative. Herpes viruses are involved in the pathogenesis of isolated retinal vasculitis. This case demonstrates that quantitative PCR is useful to detect viral DNA in AH and to monitor the viral activity and the therapeutic response.

Graves' disease can be associated with other autoimmune disorders. Primary systemic sclerosis (PSS) is such a disease characterised by multi-organ fibrosis. Abnormal thyroid antibody titres and hypothyroidism as well as hyperthyroidism have been observed in PSS patients. Specific and idiopathic inflammatory disorders are an important differential diagnosis in Graves'orbitopathy (GO). Mycophenolate mofetil (MM) is an immunosuppressive drug which depletes guanosin nucleotides in proliferating B-and T-lymphocytes. We describe the effect of MM on the endocrine orbitopathy of a patient with PSS.
