Imágenes multimodales y retromodo en la calcificación esclerocoroidea: reporte de un caso / Multimodal and retro-mode imaging in sclerochoroidal calcification: A case report

Presentamos un reporte de caso en una paciente de 70años sobre las calcificaciones esclerocoroideas, una rara condición que involucra depósitos de pirofosfato de calcio en el polo posterior del ojo. Proporcionamos un relato sobre la presentación clínica y su apariencia en imágenes multimodales, utilizando fotografías de color del fondo de ojo, tomografía de coherencia óptica de fuente de barrido (SS-OCT), ecografía ocular y la novedosa técnica de retromodo (RMI). Al examen la agudeza visual fue de 20/25 en el ojo derecho y de 20/20 en el ojo izquierdo. La fotografía de color del fondo de ojo reveló depósitos amarillentos localizados en la arcada temporal-superior de ambos ojos. SS-OCT demostró masas de origen escleral. Las ecografías oculares confirmaron la calcificación de estas masas. El RMI detectó imágenes hiperreflectivas con una marcada elevación superficial de las lesiones. El laboratorio sistémico no presentó alteraciones, lo que llevó al diagnóstico de calcificaciones esclerocoroideas bilaterales de origen idiopático.(AU)

We present a case report on sclerochoroidal calcification (SCC), a rare condition involving calcium pyrophosphate deposits in the posterior pole of the eye in a 70-year-old patient. We provide an account of the clinical presentation and its appearance in multimodal images, using color fundus photography, swept-source optical coherence tomography (SS-OCT), ocular ultrasound, and the novel retro-mode imaging (RMI) technique. Visual acuity was 20/25 in the right eye (OD) and 20/20 in the left eye (OS). Color fundus photography revealed yellowish deposits located in the upper temporal arcade of both eyes. SS-OCT demonstrated masses of scleral origin. Ocular ultrasounds confirmed the calcification of these masses. RMI detected hyper-reflective images with marked superficial elevation. Systemic laboratory results did not detect any abnormalities, leading to the diagnosis of bilateral idiopathic SCC.(AU)

Selective Photocoagulation of Capillary Macroaneurysms by Navigated Focal Laser.

BACKGROUND AND OBJECTIVE: To evaluate the anatomical and functional outcome of selective photocoagulation of capillary macroaneurysms (CMAs) by navigated focal laser. PATIENTS AND METHODS: Consecutive patients with solitary or secondary CMAs greater than 150 mm in diameter were included in this analysis. All patients were treated with navigated focal laser and received multimodal imaging. RESULTS: Seventeen eyes of 17 patients were retrospectively analyzed. Navigated laser photocoagulation of the CMAs successfully occluded 100% of the CMAs, inducing significative improvement in best-corrected visual acuity at 3 (P = .002) and 6 months (P = .001) and a decrease in central macular thickness (CMT) at 3 (P = .0004) and 6 months (P = .0004). CONCLUSIONS: Solitary or secondary CMAs arising from retinal capillaries are candidates for navigated laser treatment. Navigated focal treatment was able to close all CMAs in this series with an improvement in vision and CMT. [Ophthalmic Surg Lasers Imaging Retina. 2021;52:366-373.].

Sutureless intrascleral fixation using a uniquely designed intraocular lens.

We report our experience in the surgical technique of sutureless intrascleral posterior chamber intraocular lens (PC IOL) fixation in patients with insufficient capsular support using a uniquely designed, foldable, acrylic Carlevale IOL. It is specifically designed for sutureless scleral fixation and is equipped with a small plug attached to each of two haptics to anchor the lens to the sclera with a self-retaining mechanism. This surgery does not require creation of a scleral tunnel or transscleral exposure or excessive manipulation of the haptics. The harpoon-like plugs provide great stability to this implant, which can be injected through a 2.2mm incision. The characteristics of this IOL and the relative simplicity of this implantation technique makes it widely applicable in aphakic patients after previous complicated cataract surgery.
