Giant cell reparative granuloma (GCRG) is a rare fibroosseous lesion uncommonly seen in the orbital area. Although benign, it is known to be recurrent and locally destructive. We report two cases of GCRG of the orbit. In both cases, computed tomography revealed a heterogeneously growing well-defined mass, arising from the roof of the orbit, affecting the cortex, and invading the orbit. In the first case, the mass extended into the anterior cranial fossa. Magnetic resonance imaging with gadolinium showed, in both cases, a cystic character of the lesion with fluid levels. The surgical treatment was performed via an upper crease incision. An ultrasonic aspirator system was used to remove the tumor tissue and its extension into cranial fossa. Careful histopathologic analysis established the diagnosis of GCRG. Symptoms resolved completely with no evidence of recurrence after a follow-up of 18 and 14 months, respectively. We present the clinicopathological and radiological findings, and we describe the surgical approach. As a rare entity, GCRG of the orbit should be considered in differential diagnosis of fibroosseous orbital masses. Complete surgical excision carries a low risk of recurrence.

Purpose. To analyze patients’ anxiety levels using the Visual Analog Scale for Anxiety (VASA), in regard to intravitreal injection treatment and to determine possible associated risk factors related to the disease and treatment characteristics. Methods. Cross-sectional observational study with consecutive sampling of patients who were going to receive an intravitreal injection. Subjects completed the VASA prior to the procedure, and afterwards, their data were collected from the electronic medical history. Analysis was performed through a linear regression model. Results. Fifty-five men and forty-seven women were enrolled. The mean age was 73.9 ± 12.4 years (mean ± standard deviation (SD)), and the mean ± SD of previous injections was 12.8 ± 12. The most frequent pathologies found were age-related macular degeneration with 46.1% and diabetic macular edema with 36.3%. The median of anxiety levels measured in millimeters (mm) was 16 (interquartile range: 0–48). In univariate models, women presented a mean of 10.8 mm of anxiety more than men ( p = 0.03 ). The adjusted multivariate analysis demonstrated that younger patients declared higher anxiety levels ( p = 0.036 ). No significant association was found between the best corrected visual acuity (BCVA) on the day of the injection, the change in BCVA since the beginning of the treatment or the number of injections received, and the registered anxiety levels. Conclusions. Sex and age may have an influence on anxiety levels. BCVA and the number ofinjections received did not seem to have an influence on our patients anxiety levels.

Evaluar la pérdida celular endotelial en pacientes operados mediante facoemulsificación de catarata no complicada, comparando datos de cirujanos noveles y cirujanos expertos. Método: Se realizó un estudio observacional y prospectivo en el que se evaluaron 50 ojos consecutivos aleatorizados en dos grupos de 25 ojos cada uno. Se realizó a cada ojo recuento de células endoteliales mediante microscopía especular preoperatoriamente y al mes de la cirugía. Los ojos con cataratas complicadas fueron excluidos. Resultados: La mayoría de los pacientes eran mujeres, con una edad media de 75.5 años. La disminución de la densidad celular al mes de la cirugía fue significativa tanto en ojos operados por cirujanos expertos como por cirujanos noveles, con una pérdida del 14.8% y el 15.6%, respectivamente, sin diferencia estadísticamente significativa (p = 0.491). Además, la correlación entre la pérdida de ambos grupos fue de 0.58 (p = 0.0094). La pérdida celular en ojos operados por cirujanos noveles demostró una buena correlación (0.577) con la energía acumulada disipada del ultrasonido durante la facoemulsificación (p = 0.0025), frente a los expertos, en los que no pudo demostrarse esta asociación. El total de energía acumulada disipada empleada por cirujanos noveles fue significativamente mayor (p = 0.045), un 63% más que los expertos. Conclusiones: La diferencia en el recuento endotelial tras cirugía de catarata se demuestra asociada a la propia cirugía, con cifras similares para cirujanos noveles y expertos, y se observa una buena correlación entre ambos grupos. Teniendo en cuenta la pérdida de celularidad endotelial corneal, la seguridad del procedimiento realizado por cirujanos noveles es equivalente a la del realizado por expertos.
