Cuerpo extraño intracristaliniano / Intralenticular foreign body

Los cuerpos extraños intracristalinianos representan hasta un 10 por ciento de todos los cuerpos extraños intraoculares, por lo que su observación en la práctica oftalmológica no es frecuente. Se reportan con mayor frecuencia en varones jóvenes que han sufrido traumas en el área laboral sin la adecuada protección. De manera general, un cuerpo extraño intracristaliniano provoca disminución progresiva de la visión en la mayoría de los casos debido a la formación de catarata. Es frecuente también el aumento de la presión intraocular. Una intervención quirúrgica temprana, combinando varios procederes en un solo tiempo quirúrgico, que incluye la extracción del cuerpo extraño intracristaliniano con un fórceps, permite obtener buenos resultados visuales y el control de la hipertensión ocular. Este artículo reporta dos casos con cuerpos extraños intracristalinianos retenidos en la corteza anterior del cristalino, con información detallada sobre las circunstancias del trauma, naturaleza del cuerpo extraño y procederes médicos y quirúrgicos realizados en ambos casos con características comunes(AU)

Intralenticular foreign bodies account for up to 10 percent of all intraocular foreign bodies. That is why their observation is not frequent in ophthalmologic practice. They are more often reported in male young people who have experienced trauma while working without appropriate protection. An intralenticular foreign body generally causes progressive vision reduction due to cataract formation. Increased intraocular pressure is also common. Early surgical intervention combining several procedures in a single surgery time, including removal of the intralenticular foreign body with forceps, leads to good visual results and ocular hypertension control. The article describes two cases of intralenticular foreign bodies retained in the outer cortex of the crystalline lens, and includes detailed information about the circumstances of the trauma, the nature of the foreign body, and the medical and surgical procedures conducted in both cases with common characteristics(AU)

Endophthalmitis after Removal of an Intralenticular Foreign Body in Place without Symptoms for 20 Years

PURPOSE: We report a case of postoperative endophthalmitis in the cataract patient, associated with removal of an intralenticular foreign body that had remained in place without symptoms for 20 years. CASE SUMMARY: A 45-year-old male visited our outpatient clinic complaining of gradual visual loss in his right eye over the past 3 months. In slit-lamp examinations, anterior capsular opacification, nuclear sclerosis, and posterior subcapsular opacity were observed in the right eye. Twenty years before, a tiny metallic projectile had hit his right eye, but slit-lamp examination at the time of injury did not reveal any intraocular foreign body. We decided to undergo cataract surgery. During phacoemulsification, a metallic foreign body was found in the lens and safely removed; then an intraocular lens was implanted. As hypopyon was evident 3 days later, we injected intravitreal antibiotics and applied fortified antibiotic eye drops to the right eye. The anterior chamber inflammation improved and the best-corrected visual acuity recovered to 1.0. CONCLUSIONS: Surgeon should be aware of that endophthalmitis could develop after cataract surgery with removal of an intralenticular foreign body that had been in place for 20 years. But did not trigger inflammation or cause any symptoms as the cataract progressed.

A unilateral mild anterior uveitis due to intralenticular foreign body / 国际眼科杂志(Guoji Yanke Zazhi)

A 25-year man presented with symptom of photophobia and tearing in the right eye for 2 months duration. It was associated with painless gradual reduced vision. There was a history of hammering on a metal object prior to that. Ocular examination revealed signs of mild anterior uveitis due to a retained metallic intralenticular foreign body. Conjunctiva was white. Computed Tomography (CT) scan of the orbit confirmed presence of a single intraocular foreign body. The condition is misleading and can be easily overlooked. A detailed history and clinical examination are mandatory in this misleading situation.
