Revisión de queratocono y su enfoque como enfermedad inflamatoria

El queratocono es una condición ectásica de la córnea, que se ha descrito desde hace muchos años, y en los últimos años ha despertado mucho interés por el desarrollo de la cirugía refractiva. Clásicamente se ha considerado como un proceso no inflamatorio y se disponen varias definiciones, considerando si es un desorden clínico, topográfico o biomecánico. Los nuevos enfoques de esta enfermedad, no sólo consideran los procesos conocidos relacionados con la posible patogenia, como la alergia ocular y el frote de los párpados, sino que además consideran que se puede tratar de un problema inflamatorio crónico, relacionados con los procesos de microtrauma corneal. En esta revisión se pretende hacer una exploración de estos conceptos y relacionarlos con los conceptos clásicos de la enfermedad. relacionados con los procesos de microtrauma corneal. En esta revisión se pretende hacer una exploración de estos conceptos y relacionarlos con los conceptos clásicos de la enfermedad.246-255Keratoconus is a corneal ectatic disorder that has been described several years ago, and in recent times has aroused much interest in it because the development of refractive surgery. It has traditionally been considered a non- inflammatory process and various definitions are provided, considering whether it is a clinical, topographic or biomechanical approach. New approaches to this disease, not only considering the known processes related to the possible pathogenesis, such as allergy and eye rubbing of the eyelids, but also the theory that it can be related to a chronic inflammatory condition related to the processes of corneal microtrauma. This review is intended to make an exploration of these concepts and relate them to the classical concepts of disease

Serum creatinine as a predictor of functional and anatomical success in diabetic tractional retinal detachment

Pacientes con Desprendimiento de retina traccional diabéticoObjectives: The aim of the study was to evaluate pre-operative, intraoperative, and post-operative factors associated with functional and anatomical success in patients with diabetic tractional retinal detachment (TRD) treated with pars plana vitrectomy (PPV). Material and Methods: We retrospectively reviewed the medical records of patients with diabetic TRD surgically repaired with PPV between March 2014 and February 2015 at the Instituto de Oftalmología Fundación de Asistencia Privada Conde de Valenciana, IAP in Mexico City. A total of 250 records were reviewed and 85 met the inclusion criteria. Pre-operative, intraoperative, and post-operative variables were obtained from all records. Statistical analysis included Fisher’s exact test, Kruskal–Wallis test, and Mann–Whitney U test. Results: A total of 88 eyes of 85 patients were included in the study. The average patient age at the time of the surgery was 51.53 years (SD ± 11.99). At post-operative month (POM) 1, a greater pre-operative serum creatinine value and a greater surgical duration were associated with a worse anatomical success (P = 0.032; P = 0.014). At POM 1, 31% of the eyes with macula-involved TRD and 57.5% of the eyes without macula-involved TRD achieved visual success (P = 0.013, Fisher’s exact test). Conclusion: A greater pre-operative serum creatinine value was associated with a worse visual and anatomical outcome at POM 1. A macula-involved TRD was associated with a worse visual outcome at POM 3. Post-operative complications were associated with a worse functional and/or anatomical success at the final follow-up visit (P < 0.05).https://orcid.org/0000-0002-1310-9852Revista Internacional - No indexadaN

Tumor de tritón benigno: reporte de un caso en órbita

El artículo presenta el caso de una mujer de 49 años de edad sin antecedentes patológicos con proptosis axial progresiva izquierda de un año de evolución asociada a dolor ocular, sin cambios en la agudeza visual, sin limitación en los movimientos oculares ni diplopía. Con imágenes sugestivas de seudotumor versus schwannoma versus hemangioma cavernoso orbitario versus dermoide intraconal. Fue llevada a resección de masa vía orbitotomía anterior transconjuntival. Esta fue una lesión compatible histológicamente con hamartoma neuromuscular (tumor de tritón benigno)

Postoperative Multimodal Analysis in Successful Gas Displacement of a Submacular Hemorrhage

In this report, we describe a case of timely gas vitrectomy to displace a moderate submacular hemorrhage from the submacular space without tPA, release vitreoretinal traction along the borders of a posterior retinal tear, and analyze postoperative multimodal imaging findings in a 34-year-old male patient whose right eye was injured by a stone. The patient underwent a successful nontissue plasminogen activator gas vitrectomy 3 days after the accident. A multimodal evaluation with spectral-domain optical coherence tomography (SD-OCT), 10-2 and 30-2 campimetry, microperimetry, multifocal electroretinography (mfERG), and visual evoked potentials was performed 6 months after the accident. The multimodal imaging tests yielded abnormal foveal SD-OCT patterns, with a fibrous sealed tear in the retinal pigment epithelium. Campimetry showed low levels of retinal sensitivity; microperimetry and mfERG revealed a subnormal retinal response and a reduction in the N1 and P1 wave amplitudes. The visual evoked potential responses were normal. Multidisciplinary examination at 6 months postoperatively revealed a structurally and functionally abnormal macula. The retina remained attached. Our functional findings indicate that submacular hemorrhage should be treated in a timely manner to minimize photoreceptor damage
