摘要:

The width of the pars plana and the distances between the corneo-limbal junction and the posterior aspect of the pars plicata as well as of the ora serrata were determined by measurement in 17 autopsy eyes and additional 12 dissected autopsy eyes of premature and mature babies and infants. The data were correlated to age and length of the globe. The site of sclerotomy in transscleral lensectomy of congenital cataracts is discussed.

摘要:

Using a multimode and a fundamental mode Q-switched Nd-YAG laser, the authors study the possible damages to glass and PMMA IOLs in vitro. The fundamental parameters in this evaluation seem to be the distance between the focus and the IOL and the power delivered.

摘要:

Nine cases of hemispheric retinal branch vein occlusion (HRBVO) are discussed retrospectively after identification from among 94 cases of branch vein occlusion. The high incidence of simple chronic glaucoma (close to that found in central vein occlusion cases), the presence of vein-vein disc collaterals and the visual prognosis make it important to distinguish HRBVO cases from other branch vein occlusions.

摘要:

A 34-year-old man with Marfan’s syndrome complained of redness and pain in the left eye. The right eye had been blind because of untractable retinal detachment. The left eye had had three surgical procedures for retinal detachment, and the lens had been luxated in the vitreous for more than 14 years. Ultrasonography demonstrated the spontaneously luxated lens as the possible cause of the inflammatory reaction. The diagnosis of lens-induced endophthalmitis was confirmed by histopathologic examination of the excised len

摘要:

A case of drug-induced ocular cicatricial pemphigoid with pronounced keratinizing squamous epithelium metaplasia was treated for 5 months with all-trans retinoic acid ointment. Keratinization reversed completely and the cicatricial process was stabilized in one eye and slowed down in the other eye. The treatment was well tolerated.

摘要:

In 1985, postoperative purulent endophthalmitis (PPE) was diagnosed in 8 eyes (severe in 5 and presumed in 3 eyes). All were treated with paraocular injections of cefotaxime, gentamicin and triamcinolone with or without the same antibiotics by intraocular and/or systemic route with or without systemic corticosteroids. The suspect causative organisms were Staphylococcus epidermidis in 2 cases, Staphylococcus aureus in 3 cases, streptococcus in 1 case, in 2 cases the cause remained unknown. Pars plana vitrectomy and anterior chamber lavage were performed on 5 eyes, and anterior chamber and vitreous tap on 1 eye. The intraocular lens implants were not removed at vitrectomy. A useful vision ranging from 0.15 to 0.6 was obtained in all cases. Our present regime for the management of purulent postoperative or posttraumatic endophthalmitis is given.

摘要:

Sclerosing orbital pseudotumor is a particular type of idiopathic inflammatory process, frequently located at the orbital apex. Both from clinical and from instrumental examination the diagnosis of these forms is difficult. The ineffectiveness of steroid treatment and the progressive visual loss in these patients favors surgical exploration. We report on 5 patients who underwent exploration yielding the diagnosis of sclerosing orbital pseudotumor. Surgery allowed correct histological diagnosis and improvement of ocular symptoms.

摘要:

Induced deformations, similar to the posterior pole deformations due to advanced myopia, were studied in a series of 30 rabbits. The induced deformations were produced by means of a specially designed cup. An analysis of the applicability of the shell theory is made, and it is concluded that the thin shell theory is applicable to the mechanical study of the eyes. The basic experiment consisted of introducing a controlled deformation at different pressure levels; a wide range of types of increments and times of substained deformations were studied. It is concluded that the scleral tissue is an elastic material and has a fairly high ‘Creep’ rate. The material properties indicate that the eye can reaccommodate induced pressure, and thus glaucoma and myopia could be present without external indications of ‘high pressure’ in

摘要:

To provide a bank of normal perimetric data, we tested the central and peripheral visual fields of 102 novice normal subjects using the Humphrey automated perimeter. All eyes used for visual field testing were first carefully examined to be sure that they were, indeed, normal. We calculated population means and standard deviations of each test location and for each decade for age. Average differential light sensitivity decreased with advancing age: ––0.5 dB/decade at fixation, ––0.6 dB/decade in the central (30–2) field, and ––06. dB/decade in the peripheral (30/60–2) field. However, neither the slope nor the shape of the hill of vision changed with aging. Short-term fluctuation was not constant throughout the visual field, but instead was greater in the periphery than the center.

摘要:

Tear protein electrophoresis identifies three principal groups of proteins designated as fast-migrating proteins, globulins and postgamma protein fraction. Postgamma fraction represents 32% of total tear protein content and is antigenically constituted by lysozyme as a unique component. The clinical usefulness of determining tear lysozyme content by means of electrophoresis is pointed out.
