Fluctuaciones de presión intraocular en pacientes operados con implante de implantable collamer lens (ICL V4c). Seguimiento a 3 meses / Intraocular pressure fluctuations in patients implanted with an implantable collamer lens (ICL V4c). Three-month follow-up

Introducción: Una de las complicaciones del implante de ICL es la elevación de la presión intraocular (PIO), la cual es fluctuante y su alteración es un factor predictivo para el desarrollo de glaucoma. Material y métodos: Estudio prospectivo, transversal y analítico, en pacientes candidatos a implante de ICL. Previa valoración clínica completa, biometría y curva de PIO nocturna, posición supina, con 4 tomas, determinando la fluctuación, considerándose anormal por encima de 5 mmHg. Se les sometió a cirugía mediante técnica convencional. A los 3 meses se repitió valoración clínica completa, biometría y curva de PIO, para determinar si había cambios en las fluctuaciones de PIO. Resultados: Se estudiaron 31 ojos de 16 pacientes. El promedio de fluctuación preoperatorio fue de 3,35 ± 2 mmHg, mientras en el postoperatorio fue de 3,0 ± 2,2 mmHg, sin que esta diferencia fuera estadísticamente significativa. La agudeza, capacidad visual y equivalente esférico mostraron una mejoría estadísticamente significativa. Hubo 6 casos con complicaciones, las cuales se relacionaron con un vault alto y un ICL de mayor tamaño. No hubo relación entre estos hallazgos con el grado del ángulo camerular, el grado de pigmento o el nivel de entrenamiento del cirujano. Conclusión: Se exploró por primera vez el efecto del implante de ICL en las fluctuaciones de PIO, encontrando que no es estadísticamente significativo. Se mostró la seguridad y reproducibilidad del procedimiento, como en publicaciones previas, agregando que el nivel de entrenamiento del cirujano no es un factor determinante en estos hallazgos

Introduction: Fluctuating elevated intraocular pressure (IOP) is one of the complications of an implantable collamer lens (ICL), and its alteration is a predictive factor for the development of glaucoma. Material and methods: A prospective, cross-sectional analytic study was conducted on patients suitable for ICL implantation. Complete clinical and biometric work-ups were performed, as well as night-time IOP curve, in supine position, with 4 determinations, in order to assess fluctuation, considering abnormal with a value higher than 5 mmHg. Patients underwent surgery with conventional technique and three months after the work-ups were repeated, including a night-time IOP curve to assess any changes in IOP fluctuations. Results: A total of 31 eyes of 16 patients were studied. Mean IOP fluctuation in the preoperative assessment was 3.35 ± 2 mmHg, whereas the postoperative mean was 3.0 ± 2.2 mmHg, with the difference not being statistically significant. Visual acuity and capacity, as well as spheric equivalent did show a statistically significant improvement. There were 6 cases of complications, which were related to a higher vault and a greater ICL size. There was no relationship between these findings and the angle grade, pigment, and the level of training of the surgeon. Conclusions: The effect of an ICL on IOP fluctuations, has been studied for the first time, which was found to be not statistically significant. As in previous publications, the procedure was safe and reproducible, adding the fact that the level of training of the surgeon is not a determining factor in these findings

Caso clínico: hemangioendotelioma epitelioide orbitario / Case report: Orbital epithelioid haemangioendothelioma

CASO CLÍNICO: Paciente masculino de 13 años de edad, el cual presenta proptosis y desplazamiento lateral de ojo derecho. Se palpa tumoración blanda no pulsátil en región orbitaria superomedial. Se realizó biopsia excisional de la masa que fue informada como hemangioendotelioma epitelioide. DISCUSIÓN: El hemangioendotelioma epitelioide es un tumor vascular de comportamiento intermedio entre tumores vasculares malignos y benignos. Estos pueden presentarse en tejidos blandos o a partir de hueso. En la literatura hay pocos casos publicados de aparición en órbita

CASE REPORT: A 13-year-old boy presented with right eye proptosis and lateral dystopia. A soft non-pulsatile mass was found in the superomedial orbital region. An excisional biopsy was performed, for which the histopathology reported an epithelioid haemangioendothelioma. DISCUSSION: Haemangioendothelioma is a borderline vascular lesion within the spectrum of clinically benign and malignant tumours. These can arise from soft tissue or bone. There are few reports of these tumours located in the orbit
