ABSTRACT

CASE REPORT: An 18-year-old man, presented a lower vitreous hemorrhage of unknown cause. Multiple tests are performed, including Ophthalmic Ultrasound and Fluorescein Angioghaphy (FA), they did not find justification of bleeding. Finally, we decide to do a Biomocroscopía Ultrasonic (UBM) showing an iridociliary cyst. DISCUSSION: The iridociliary cysts are single or multiple, primary or secondary. The primaries are usually benign so, they do not require treatment. When the cyst has a considerable size, it may produce a focal plateau iris with or without angle-closure. Our case reveals an unusual complication that should take notice of when you have an unknown vitreous hemorrhage.

ABSTRACT

CLINICAL CASE: A 45 year-old woman with unknown ophthalmology history complained of pain, redness and visual acuity (VA) loss in her left eye for the last three weeks. A serous iris cyst with an overlying peripheral corneal leukoma was located in the iris stroma using ultrasonic biomicroscopy. It was assumed that it was secondary to a penetrating trauma from her childhood. The cyst healed and VA improved after fine-needle aspiration and partial posterior synechiolysis. DISCUSSION: Iris inclusion cysts may appear many years after penetrating trauma or surgery. Fine-needle aspiration is a good choice for its diagnosis and treatment.

ABSTRACT

OBJECTIVE: To evaluate patients 24 months after deep sclerectomy (DE) with supraciliary implant, and identify any predictive success factors by examination with ultrasound biomicroscopy (UBM) MATERIAL AND METHODS: This study included 26 eyes of 23 patients evaluated by UBM 24 months after a deep sclerectomy with a supraciliary hema implant. RESULTS: There was a significant reduction in intraocular pressure (IOP), changing from a preoperative mean of 25.6 ± 6.4 mmHg to a postoperative mean of 16.2 ± 3.4 mmHg (P<.001). The number of preoperative glaucoma medications also decreased from 2.5 ± 0.6 drugs per patient to 0.5 ± 0.5 (P<.001). No change was observed in the best-corrected visual acuity. The anatomical characteristics of the surgical area, and its relationship with IOP were examined using UBM. There was no correlation between the level of IOP at the time of UBM and the horizontal (r=-.05: P=.71) and vertical diameter (r=-.1; P=.63), the height (r=.28; P=.25) and the volume of intrascleral space (r=-.08; P=.79), the thickness (r=-.07; P=.73) and the length (r=.39; P=.13) of trabeculo-Descemet's membrane (TDM), the presence of filtering bleb (P=.30) and the hypoechoic area in the supraciliary space (P=.24). CONCLUSIONS: The insertion of a hema implant in the supraciliary space is an effective and safe surgery for patients with open angle glaucoma (OAG). No predictive success factors for supraciliary implant were found using the UBM study.

ABSTRACT

PURPOSE: The purpose of this study was to evaluate the effect of pharmacologic pupillary dilatation on anterior chamber depth (ACD) and anterior chamber angle (ACA) in eyes with exfoliation syndrome (XFS). METHODS: Thirty-six eyes of 36 patients with XFS were evaluated with slit-lamp examination, Goldmann applanation tonometry and ultrasound biomicroscopy (UBM) under standard light conditions. Primary outcome parameters were defined as the change in ACD and ACA measured before and 40 min after instillation of a single drop of either 1% cyclopentolate (Group I; n=12), 2.5% phenylephrine (Group II; n=12) or 1% tropicamide (Group III; n=12). Change in intraocular pressure (IOP) during the same time interval was included as a secondary outcome measure. RESULTS: The average predilatation ACD, ACA and IOP values in the study subjects were 2.54±0.40 mm, 27.9±6.3° and 14.9±3.1 mmHg, respectively. There were no significant differences in the mean age (p=0.461), the female/male ratio (p=0.232), baseline ACD (p=0.841), ACA (p=0.761) or IOP (p=0.070) within the three groups. Differences in dilation induced changes in ACD (p=0.108), ACA (p=0.636) and IOP (p=0.160) between the three groups were not statistically significant. CONCLUSION: Pupillary dilatation with a single drop of 1.0% cyclopentolate, 2.5% phenylephrine or 1% tropicamide is not associated with shallowing of the anterior chamber or narrowing of the ACA in patients with XFS who present with open angles.

ABSTRACT

CLINICAL CASE: A 5 year-old child diagnosed with moderate anisometropic amblyopia secondary to primary cyst of iris pigment epithelium. He was evaluated with ultrasound biomicroscopy (BMU) and optical coherence tomography (OCT) of anterior segment. DISCUSSION: The OCT, although with some limitations, is a useful tool to study the anterior segment. It is probably more recommendable than BMU in the childhood.

ABSTRACT

OBJETIVO: Determinar la posición efectiva del lente intraocular en la facoemulsificación diagnosticado por biomicroscopia ultrasónica y su relación con la "sorpresa refractiva" posquirúrgica. MÉTODOS: Se realizó un estudio descriptivo y prospectivo de una muestra de 176 ojos de 100 pacientes operados de catarata por facoemulsificación con la técnica de Pre chop, en el Servicio de Microcirugía Ocular del Instituto Cubano de Oftalmología "Ramón Pando Ferrer", a los que se le determinó la posición efectiva del lente intraocular en la facoemulsificación diagnosticado por biomicroscopia ultrasónica y su relación con la "sorpresa" refractiva posquirúrgica. RESULTADOS: La mayoría de los pacientes estudiados, fueron del sexo masculino de la tercera edad, se diagnóstico la posición efectiva del lente intraocular en saco-surco por biomicroscopia ultrasónica, con lo que se logró la mejor agudeza visual corregida posoperatoria en todos los grupos de estudio, la distancia de la cara posterior del iris al lente intraocular, diagnosticada por biomicroscopia ultrasónica, en pacientes con lente intraocular en saco capsular demostró un valor constante, la mayoría de pacientes normo corregidos tenían el lente intraocular en saco capsular, los lente intraocular ubicados en la posición saco-surco, cuya háptica se encontraba con mayor angulación, tenían un cilindro posoperatorio promedio mayor, no se encontraron diferencias significativas entre el cilindro posoperatorio promedio obtenido. CONCLUSIONES: Queda demostrada la importancia de la biomicroscopia ultrasónica en la determinación de la posición del lente intraocular en los pacientes operados. Es determinante la localización del lente intraocular en el defecto refractivo posoperatorio, se destaca en la posición saco surco la existencia de un cilindro posoperatorio mayor.


OBJECTIVE: To determine the effective position of the intraocular lens in the phacoemulsiphication diagnosed by ultrasonic biomicroscopy and its relationship to the postsurgical refractive surprise. METHODS: A prospective and descriptive study was performed in a sample of 176 eyes from 100 patients, who had been operated on from cataract with phacoemulsiphication using Pre Chop technique in the Ocular Microsurgery Service of "Ramón Pando Ferrer" Cuban Institute of Ophthalmology". The effective position of their intraocular lens diagnosed by ultrasonic biomicroscopy in the phacoemulsiphication and their relationship to the post surgery refractive surprise was determined. RESULTS: Most of the studied patients were older adult males. The ultrasonic biomicroscopy diagnosed the effective position of the intraocular lens in sac-sulcus to achieve the best postoperative corrected visual acuity in all the studied groups. The distance from the posterior face of the iris to the intraocular lens found in patients with intraocular lens in capsular sac showed a constant value. Most of the normocorrected patients had their intraocular lens in the capsular sac whereas the intraocular lens located in sac-sulcus position, whose haptics exhibited bigger angle, had bigger postoperative average cylinder, no significant differences were found among the postoperative average cylinders. CONCLUSIONS: The importance of the ultrasonic biomicroscopy is demonstrated in the determining the position of the intraocular lens in the surgical patients. The location of the intraocular lens is decisive in the postoperative refractive defect; bigger postoperative cylinder was more often found in the sac-sulcus position.

ABSTRACT

OBJETIVO: Determinar la correlación entre la localización del lente intraocular en cámara posterior por biomicroscopia ultrasónica, diferentes parámetros quirúrgicos en pacientes operados de catarata. MÉTODOS: Se realizó un estudio descriptivo, prospectivo y transversal en el Instituto Cubano de Oftalmología Ramón Pando Ferrer durante el período de enero a junio del 2007. Se estudiaron variables como: edad, sexo, etiología de la catarata, técnica quirúrgica, localización del lente intraocular según biomicroscopia ultrasónica, así como complicaciones transoperatorias y posoperatorias. RESULTADOS: El 79 por ciento de todos los pacientes operados tenían entre 60 y 79 años de edad y algo más de la mitad correspondió al sexo femenino con un 59 por ciento. La catarata senil fue la etiología que predominó con un 74 por ciento y en el 68 por ciento de los casos el lente se localizó por biomicroscopia ultrasónica en el saco capsular. En los ojos donde el lente intraocular se localizó fuera del saco, la proporción de complicaciones transoperatorias y posoperatorias fueron significativamente mayoritarias, mientras que en los ojos donde el lente intraocular se encontraba en el saco, la mayoría no presentó complicaciones transoperatorias ni posoperatorias. CONCLUSIONES: Las diferencias entre las distintas localizaciones del lente intraocular se encontraron con significación estadística en el tipo de catarata, la presencia de complicaciones transoperatorias y posoperatorias, sin embargo, no se encontró relación estadística significativa entre la localización del lente intraocular con la técnica quirúrgica utilizada(AU)


OBJECTIVE: To determine the correlation between the location of the intraocular lens in the posterior chamber using ultrasonic biomicroscopy and the different surgical parameters in patients operated from cataract. METHODS: A prospective, descriptive and cross-sectional study was carried out in Ramón Pando Ferrer Cuban Institute of Ophthalmology in the period of January to June 2007. The studied variables were age, sex, etiology of cataracts, surgical technique, location of the intraocular lens using ultrasonic biomicroscopy, as well as transoperative and postoperative complications. RESULTS: Seventy nine percent of all the surgical patients were 60-79 years of age and 59 percent were females. The senile cataract was the prevailing etiology for 74 percent and the lens was located in the capsular sac using ultrasonic biomicroscopy in 68 percent of the cases. In those eyes where the intraocular lens was off the sac, the ratio of transoperative and postoperative complications was significantly higher, whereas most of the eyes with the IOL placed in the sac did not have either transoperative or postoperative complications. CONCLUSIONS: The differences between the different locations of the intraocular lens were statistically significant in terms of the type of cataract; however, there was not any significant statistical association between the location of the intraocular lens and the surgical technique(AU)
