Malignant glaucoma is an entity characterized by intraocular pressure (IOP) with a shallow anterior chamber in the presence of a patent peripheral iridectomy. In its classic form, malignant glaucoma is rare but one of the most serious complications of fistulizing surgery in patients with narrow angle or angle closure glaucoma. In this case we have a female patient who developed crisis of ciliary block glaucoma (malignant) during performance of circadian IOP curve with dynamic contour tonometer.

PURPOSE: To determine the reproducibility of the peripapillary retinal nerve fiber layer thickness and optic nerve head parameters measured with the optical coherence tomography (SD-OCT) in normal eyes. METHODS: Thirty-four eyes of 34 healthy patients were included in the study. The Cirrus OCT optic disc cube 200×200 protocol was used to obtain three scans from each eye to evaluate the reproducibility. Intraclass correlation coefficient (ICC) was calculated for the measurements of retinal nerve fiber layer thickness and optic nerve head […]

PURPOSE: To develop free software (SAEVI) to improve the vision stimulation services. METHODS: The software of visual stimulation service (SAEVI) was developed in microsoft Acess®, version 2003. Results: This database management system allows an efficient patients control and specific patient’s appointments, such as: ophthalmological diagnostic and year of the appointment, and also other options, providing reports of each item. CONCLUSION: Professionals who work with visual stimulation or in related areas may be benefited from using the software to organize their […]

PURPOSE: To evaluate the inflammatory response in the choroid, retina and vitreous in rabbit eyes underwent cryotherapy followed by intravitreal triamcinolone acetonide and to compare with those underwent cryotherapy followed by intravitreal injection of saline solution. METHODS: This is a prospective case-control study. Surgical procedures were performed in eleven rabbits. Two animals were excluded because they did not complete the postoperative period or had intraoperative or postoperative complications. All rabbits underwent superior temporal peritomy and transscleralcryotherapy in both eyes. After […]

OBJECTIVE: Evaluate accuracy and reproducibility of streak retinoscopy without neutralising lenses in experimental hyperopia of an artificial eye. METHODS: Observe a Welsh Allynretinoscope streak through the pupil of an artificial eye prepared do show hyperopia from +1,00 D to +8,00 D. The streak was moved while varying its width by sliding the sleeve upwards until neutralisation point. The retinoscope was fitted either with a millimetre scale under the sleeve or with a multimetre connected to a rheostat driven by a […]

PURPOSE: To evaluate the contact lenses fitting with respect to visual improvement in patients with keratoconus. METHODS: We conducted a prospective study of 54 patients (99 eyes) attending the Contact Lens Clinic of Faculdade de Medicina do ABC (FMABC) from january 2010 to november 2010. Data were collected on gender, age, treated eyes, degree of keratoconus, initial visual acuity (VA) and final VA after fitting. RESULTS: Of the patients, 44% were women and 56% men. Forty-six point forty-seven percent of […]

PURPOSE: The methodology currently used for interpretation of the cornea and anterior segment tomography for the diagnosis of corneal ectasia and its susceptibility. METHODS: Description of the methodology and clinical interpretation of corneal and anterior segment tomography indexes; report of three cases demonstrating the importance of this new diagnostic tool (Pentacam HR®) in ophthalmological practice. CONCLUSION: The use of corneal and anterior segment tomography seems to be an effective method to increase the sensitivity and specificity for the diagnosis and […]

OBJECTIVE: Ocular changes in special due to volume loss in eviscerated cavities promote several psychological aesthetic and functional alterations to patients. For this reason, searches aiming at finding a material of low cost and biocompatibility have been constantly carried out. Test experimentally the implants constituted of ultra-high molecular weight granular polyethylene oflow cost, in orbits of rabbits subjected to surgical evisceration in several experimental times, evaluating the macro and microscope aspects besides the systemic toxicity of the material. METHODS: In […]
