Treatment of rat eyes with cryopexy enhanced the development of experimental autoimmune uveitis (EAU) in these eyes. The enhancement of EAU by cryopexy was particularly pronounced when the disease was induced by active immunization in rats of a low responder strain (Wistar Furth), or by adoptive transfer with lymphocytes sensitized against S-antigen. The disease enhancement was expressed by ear...

A retrospective study of 106 eye which have undergone prophylactic circumferential cryopexy is presented. The complications involving the anterior segment were iritis, transient cycloplegia, as fixed dilated pupil, and cataract formation. Those involving the posterior segment were vitreous, subchoroidal and retinal haemorrhage, and preretinal fibrosis. The incidence of retinal detachment was 7....

A baby born at 25 weeks gestation with a birth weight of 800 g who suffered from severe respiratory distress syndrome with metabolic acidosis is described. Active retinopathy of prematurity, stages II and III, was found in the right eye at the age of 1 month and in the left eye a month later. Both eyes were treated by peripheral cryopexy. The pathological examination showed that cryopexy was ef...

PURPOSE To measure the vWF antigen concentration (vWF Ag) in subretinal fluid (SRF) and blood plasma. METHODS Prospective study of 30 patients, aged from 15 to 78 years (mean 52.7 years), undergoing retinal detachment surgery. Excluded were patients with venous or arterial disease or any other factors that could affect the parameters evaluated. Subretinal samples were obtained at the time of ...

Purpose. To observe the long-term effectiveness of scleral buckling and transscleral cryopexy conducted under a surgical microscope in the treatment of uncomplicated rhegmatogenous retinal detachment. Methods. This was a retrospective analysis in a total of 227 consecutive patients (244 eyes) with uncomplicated rhegmatogenous retinal detachment (proliferative vitreoretinopathy ≤ C2). All patien...

PURPOSE To investigate the vitreous findings in patients with cicatricial retinopathy of prematurity (ROP) who underwent retinal cryopexy and/or photocoagulation during the acute phase of the disease. METHODS Vitreous findings were evaluated in 15 patients (29 eyes) with cicatricial ROP by slit-lamp biomicroscopy and indirect ophthalmoscopy. RESULTS The ocular examination revealed that all ...

Cyclodialysis is the result of the separation of the longitudinal fibres of the ciliary muscle from their scleral insertion, creating states of ocular hypotony. It is mainly caused by traumatisms. Gonioscopy has traditionally been the diagnostic test for this entity, however, at present it is being replaced by other techniques, such as ultrasound biomicroscopy (UBM). We present the case of a 57...

Forty-five out of 50 selected retinal detachments were successfully reattached by the D-ACE surgical sequence, that is, initial drainage of subretinal fluid followed by air injection into the vitreous, transcleral cryopexy, and definitive scleral buckling. The D-ACE sequence is recommended for difficult bullous detachments as a simple, safe, and effective alternative to non-drainage techniques.
