ABSTRACT Acute corneal hydrops is an ophthalmologic emergency resulting from rupture of Descemet’s membrane with entry of aqueous humor into the corneal stroma. Patients typically present with ocular pain, blurred vision, photophobia, and tearing. The main risk factors include trauma due to ocular itching, allergic keratoconjunctivitis, corneal ectasia, and Down syndrome. Although a rare complication, it is most commonly associated with keratoconus. Clinical treatment with eye drops should always be initiated, but in advanced cases, combined surgical intervention may be […]

Schnyder’s corneal dystrophy (SCD) is a rare corneal condition characterized by cholesterol and phospholipids deposition in the stroma and Bowman’s layer. We present a case report of a patient who had a progressive corneal stromal haze in both eyes since he was 15 years old. Etiological diagnosis of SCD was well established by In Vivo Confocal Microscopy (IVCM).

PURPOSE: Observe the effects of corneal intrastromal injection of biguanide at 0.02%, 0.1% and 0.5% in rabbits’ eyes. METHODS: Doble blind prospective study. 8 rabbits were used, randomly identified and divided into 4 groups, with 2 rabbits each, with the administration of 0.2 ml of the drug via intrastromal, in the right eye. The first group received biguanide at a concentration of 0.02%, the second one at 0.1%, the third at 0.5% and the fourth group (control) was given a […]

PURPOSE: Evaluate the effect of micro puncture with radiofrequency as treatment of symptomatic patients with bullous keratopathy. METHODS: Prospective study in 10 pacients with syntomatic bullous keratopathy and low vision. Micro puncture with radiofrequency was made in areas of the anterior stromal that had an epithelial descompensation. The evaluation of the patients was realized trough clinical examinations (biomicroscopy, pachymetry, tonometry and esthesiometry) and symptom graduation (pain intensity, foreign body sensation, photophobia and insomnia caused by pain). RESULTS: The comparisons of […]

PURPOSE: Demonstrate the possibility of changing the biomechanical behaviour of cornea stroma by usage of riboflavin associated with non-ultraviolet light. METHODS: Double blind prospective study. Twenty five porcine eyes enucleated 24 hours before the experiment, have been divided on the following groups : Riboflavin 0,1% with irradiation of blue light, Riboflavin 0,1% without irradiation of light , Riboflavin 0,5% with irradiation of blue light, Riboflavin 0,5% without irradiation of light and BSS with irradiation of light. RESULTS: Differences where noticed […]

The purpose of this paper is to describe the clinical aspects of one case with deep corneal vascularization after corneal ring implantation to treat corneal ectasia due to LASIK 4 years before. The corneal ectasia diagnostic was performed by corneal pachimetry and topography. Intrastromal corneal ring segment was implanted. On the third year of follow-up, extrusion of one segment was noted and deep corneal neovascularization was found. The segment was removed, laser photocoagulation was applied and complete vascular regression was […]
