ABSTRACT
PURPOSE: To evaluate the effect of EVO+ Visian Implantable Collamer Lens (ICL) implantation on the iridocorneal angle pigmentation and structures. METHODS: Myopic refractive surgery candidates who underwent posterior chamber EVO+ ICL implantation were evaluated preoperatively and 3 and 6 months postoperatively. High-resolution images of the iridocorneal angle (nasal, superior, temporal and inferior quadrants) were acquired during gonioscopy. A masked observer, blinded to study visits and patients' information, evaluated the angle width, apparent iris root insertion, iris configuration, and trabecular meshwork pigmentation according to the Spaeth scale in two different occasions. The intra-rater reliability was estimated using the weighted Gwet's Agreement Coefficient (AC2). Differences between visits were analyzed using the Cochran Q test or the Friedman test. RESULTS: Twenty-one patients (13 females and 8 males) aging 31.3 ± 6.3 years old were recruited. The intra-rater reliability of gonioscopy assessment was excellent for every parameter assessed (AC2 ≥ 0.97). No significant differences were found among the study visits for any quadrant in the angle width (p ≥ 0.74), apparent iris root insertion (p ≥ 0.22), iris configuration (p ≥ 0.21) and trabecular meshwork pigmentation (p ≥ 0.24). Mean pigmentation of trabecular meshwork for the four quadrants did not vary either among visits (p = 0.25). CONCLUSIONS: The EVO+ ICL implantation after uneventful procedures appears not to clinically affect the iridocorneal angle pigmentation and/or structures during a short-medium follow-up using gonioscopy assessment. The intra-rater reliability of glaucoma specialists assessing iridocorneal angle structures using gonioscopy images is very high.

Objetivo: Describir el caso de un paciente joven con antecedente de miopía bilateral y degeneración en Lattice en el ojo izquierdo (OI), que desarrolló un desprendimiento de retina bilateral después de realizar una actividad de alto riesgo tipo bungee jumping. Diseño: Reporte de caso. Metodología: Reporte de caso retrospectivo mediante la recopilación de datos clínicos, estudios imagenológicos y valoraciones postoperatorias. Resultado: Recuperación de la agudeza visual posterior a tres procedimientos quirúrgicos de 20/400 en ojo derecho (OD) y de 20/30 en OI en el paciente con antecedente de desprendimiento de retina bilateral. Conclusión: El desprendimiento de retina traumático secundario a actividades de alto riesgo donde está implicado el movimiento de latigazo es poco común, sin embargo, la identificación temprana de patologías como la miopía y degeneración en lattice, en personas que van a realizar deportes extremos, debe considerarse. También es importante que las compañías que promocionan este tipo de actividades conozcan esta patología, ya que a pesar de ser infrecuente, puede llegar a desarrollarse.
Purpose: To describe the case of a young patient with a history of bilateral pathologic myopia and lattice degeneration in the left eye who developed bilateral retinal detachment after making a bungee jumping activity. Design: Case report. Methods: A descriptive, case report study type was performed by collecting clinical data, imaging studies and postoperative evaluations. Result: Subsequent recovery of visual acuity after three surgical procedures of 20/400 in right eye and 20/30 in the left eye in the case report patient with a history of bilateral retinal detachment. Conclusion: Traumatic retinal detachment secondary to high-risk activities where is involved the whipping motion is uncommon, however, early identifi cation of diseases as myopia and lattice degeneration in people who practice this extreme sports should be identifi ed. It is also important that companies promoting such activities acquire knowledge about it, taking into account, that despite it is a rare disease, it may develop.
