Protocol for Comparing Benzodiazepine-Ketamine and Benzodiazepine-Fentanyl Sedation in Phacoemulsification (BEKEF): A Double-Blind Crossover Non-Inferiority Clinical Trial Study.

Background: Cataract surgery, particularly phacoemulsification, often requires sedation alongside topical anesthesia to manage patient anxiety and discomfort. This protocol proposes a study comparing the efficacy of ketamine and fentanyl, both combined with benzodiazepine, as sedation options for patients undergoing bilateral phacoemulsification.

Methods: In a randomized, double-blind, crossover clinical trial, at least 48 patients scheduled for bilateral cataract surgery will receive fentanyl with midazolam for one eye and ketamine with midazolam for the other.

Autofluorescence and spectral-domain optical coherence tomography of optic disk melanocytoma.

The authors report fundus autofluorescence (FAF) and spectral-domain optical coherence tomography (OCT) findings of two consecutive patients who presented with optic disk melanocytoma (ODM). A retrospective study was performed by reviewing medical records and ophthalmic imaging examinations. Optical coherence tomography findings were sloped and brightly reflective anterior tumor surface, adjacent retinal desorganization and abrupt posterior optical shadowing.

Fundus autofluorescence in blunt ocular trauma.

Purpose: To describe the findings of fundus autofluorescence (FAF) imaging in patients with blunt ocular trauma.

Methods: In this non-interventional retrospective study, we reviewed medical records and imaging examination results. The data analyzed included gender, age, laterality, trauma etiology, time between trauma and imaging, visual acuity, changes in the retinal periphery, fundus examination results, and FAF imaging findings.

Retinal vasoproliferative tumor.

Retinal vasoproliferative tumor is a rare disease that has capillary hemangioma as the most frequent diferential diagnosis. The tumor is considered to be of reactive nature. It can be idiophatic or secondary to other ocular diseases such as: uveitis, retinitis pigmentosa, sickle cell disease, previous surgery and retinopathy of prematurity.

Isolated uveal tuberculoma masquerading as an intraocular tumor in an immunocompetent patient-a clinical-pathologic study with diagnosis by PCR.

Purpose: The aim of this article is to report a case of uveal tuberculoma simulating an intraocular tumor in which the diagnosis was only possible by polymerase chain reaction (PCR) analysis.

Method: This is a case report.

Results: A36-year-old male presented with a progressive growing intraocular tumor and no history or positive test for other systemic disease.

Optical coherence tomography findings in acute phase of branch retinal artery occlusion: case report.

to report a case of branch retinal artery occlusion in the acute phase, using optical coherence tomography to evaluate the morphologic changes. A 27 year-old man had a sudden superior scotoma in the right eye, with fundus examination compatible with inferior temporal branch retinal artery obstruction. The optical coherence tomography revealed increase in thickness and hyper-reflectivity of the inner retinal layers in affected area, with decreased reflectivity of photoreceptor and retinal pigment epithelial layers.

[Histopathologic confirmation of vascular and nervous tissue identified on ultrasound as an tangential image to choroidal detachment: report of two cases].

Two cases of endophthalmitis with choroidal detachment submitted to enucleation are presented. The histopathologic study allowed the identification of vascular and nervous tissue between the choroid and sclera, as it was seen on ultrasound examination.

[Retinocytoma: report of five cases].

Five retinocytoma cases diagnosed over 75 months are reported. The mean age at diagnosis was 193.2 months.

Foreign body after pterygium surgery simulating an epibulbar tumor.

A 60-year-old woman was referred for evaluation of a rapidly growing conjunctival neoplasm after pterygium surgery. The lesion proved to be a foreign body granuloma, with exogenous material that seemed to be cotton mesh, probably used for tamponade of subconjunctival bleeding that was unintentionally left in place.

[Aneurysmal bone cyst of the orbit - a clinicopathological study: case report].

Aneurysmal bone cyst of the orbit is a rare disease that usually affects young patients and is caused by osseous hemodynamic alterations. We report a case of aneurysmal bone cyst of the orbit, referred to us as a dermoid cyst, discussing its clinical and histopathological aspects.

We report two cases of true capsular exfoliation occurring in elderly patients with no known history of prolonged heat exposure or intraocular inflammation. The biomicroscopic aspects, histopathologic findings and possible surgical implications are discussed.

[Cystic orbital teratoma: clinicopathologic study: case report].

We report on a case of an congenital orbital tumor of impressive size, occurring in a newborn. The patient underwent orbital exenteration with a histopathologic diagnosis of cystic teratoma. The clinicopathological aspects of such a rare disease are commented.
