[Larva migrans syndrome or ocular toxocariasis]. / Síndrome de larvas migrantes o Toxocariasis ocular.

Thirteen cases of ocular toxocariasis attended in the Oftalmology Service of the Pediatric Hospital "Niño Jesús", from Córdoba; and in the Parasitology and Micology Cathedra of the Medicine Collegue of the University of Córdoba were studied from July 1993 till July 1995. The authors determine the needs of taking into account this parasitosis; above all in children and with the antecedent of contact with pets.

[Significative lengthening of the time of cornea conservation supporting its natural tension and curvature]. / Significativa prolongación del tiempo de conservación de la córnea manteniendo sus tensiones y curvatura naturales.

The success of cornea transplantations has always been a concern of world researchers to identify risk factors from the proper surgical techniques up to the several tissue storage procedures, such as the ones used in the new laboratories called eyes banks. However, the integral research works are still limited at present and they continue putting emphasis in the donor cornea storage that guarantee up to for this tissue feasibility. This research had the aim to contribute to the improvement of the corneal tissue quality taking into account the maintenance of its natural curvature and tensions combining them with some standard preservation solutions. This was achieved by means of a new mechanical system. Assays with rabbits were designed according to a sequential experimental groups design. In these ones, the study of the feasibility parameters behavior under different conservation media, related to the time, was splitted into four blocks. The first and second ones attended the cornea conservation in the short and intermediate-terms culture mediums as the ones at 4 degrees C degree isolated cornea preservation and the usual ones such as the Mc Carey Kaufman, Optisol and Likorol solutions used in the eyes banks. The third one was designed for the surgical assays coming from the two named groups and the last one focused the time study of these parameters for a new conservation technique, developed as an alternative medium to keep the cornea tissue curvatures and tensions as well as its nutrition and hydration. The results showed that tissue natural tensions maintenance is an significant factor in the conservation process, which involve the cornea feasibility for the its use in future transplantations. Since the new developed technique is very simple, this study is considered to be a significant contribution for the storage and biological material handling steps.

[Surgery of glaucoma: intrascleral trabeculo-irido encleisis]. / Cirugia del glaucoma: trabéculo-irido-encleisis intraescleral.

The objective of this work is to appraise a surgical proposal for the treatment of glaucoma which attempts to avoid the relapses and complications. The technique consists of the fulfillment of a filtering blister (chamber of pressure derivation) using a support of corneoscleral trabeculae together with a support of iris placed into the sclera through a scleral flapping. 70 patients (125 eyes) with more than 7 years after surgery with this technique were selected at random. Their field of vision and eye pressure were evaluated and biomicroscopy and gonioscopy were practiced. The efficiency was of 95%, and patients with a field of vision between 10 and 20 degrees, and with pressures higher than 40 mmHg before surgery showed an improvement of an average of 5 degrees. The results are based on the successful endothelization of the accessory chamber achieved and in the building of a bond that stops the closing of the channel between the anterior and accessory chambers. The results of this long term follow-up suggest that the technique analyzed offers a good alternative to the surgery of glaucoma.
