Bilateral simultaneous optic neuritis in childhood systemic lupus erythematosus. A case report.

The authors describe an 11-year-old girl with systemic lupus erythematosus (SLE) who developed simultaneous bilateral acute optic neuritis. Severe initial visual loss followed by permanent visual deficit occurred in both eyes despite therapeutic intervention. Recurrence of optic neuritis in one eye caused the vision to deteriorate further. The most probable pathogenesis is occlusive vasculitis involving the small arterioles of the optic nerves.

A comparison between donor-recipient corneal size and its effect on the ultimate refractive error induced in keratoconus.

A prospective randomized clinical study was performed to see the effect of donor-recipient corneal size on the ultimate refractive error induced in keratoconus at our facility. The patients were randomly divided into two groups, A and B. In Group A, the difference in size between the donor and the recipient cornea was 0.25 mm (18 patients). In Group B, the difference in size between the donor and the recipient cornea was 0.50 mm (20 patients). Both groups underwent the surgical procedure with the same surgeon (M.A.J.) and the same technique. Two months after suture removal, keratometry readings and refractive errors induced were compared. The mean keratometry reading in Group A was 43.3 diopters; in Group B, the reading was 44.8 diopters. There was a mean difference of 1.5 diopters between the two groups (p = 0.01). The mean refractive error in terms of spherical equivalent in Group A was -1.55 diopters and in Group B was -3.33 diopters. There was a difference of -1.8 diopters between the two groups (p < 0.05).

Superficial juvenile granular dystrophy.

Seventeen cases of a superficial corneal dystrophy are presented. The lesions are subepithelial, limited mainly to Bowman's layer. This dystrophy, although clinically different from classic granular dystrophy, is pathologically similar to it. Treatment, consisting of superficial keratectomy to 15% to 20% of corneal thickness, did not require lamellar grafting and produced good visual results. A new classification of granular dystrophy is proposed.

Association of herpetic encephalitis with acute retinal necrosis syndrome.

Bilateral acute retinal necrosis syndrome developed shortly after a severe acute encephalitis in two previously healthy adults. The clinical and laboratory data suggested that herpes simplex virus was the cause of the encephalitis and acute retinal necrosis in these patients. To the authors' knowledge, this is the first report of an association of herpetic encephalitis with acute retinal necrosis in the literature.

Posterior segment triple surgery after traumatic eye injuries.

Cataract extraction, posterior chamber intraocular lens (PC-IOL) implantation, and complete vitrectomy combined in a one-stage procedure were performed in 16 eyes (16 patients) with traumatic eye injuries undergoing anterior lensectomy (seven eyes), extracapsular cataract extraction (six eyes), or pars plana lensectomy (three eyes). Membrane peeling and intraocular foreign-body removal (13 eyes, 6 with intraretinal foreign bodies) were performed as needed. Surgery was performed from 1 week to 10 years after injury. After an average follow up of 8 months, 13 eyes (81%) had a visual acuity of at least 20/200; 50%, at least 20/40.
