The authors report two cases of medullo-epithelioma of ciliary body found in two young children. They describe the main clinical symptoms which are often non specific (cataract, glaucoma). Diagnosis is based on histological findings following enucleation: the tumor is developed from the ciliary body cells and has often a local malignancy. Metastasis are rare.

Primary cilia are sensory organelles that regulate various signaling pathways. When microtubules are compared to a highway, motor proteins carry and transport cargo proteins, which are tuned by post-translational modifications, such as acetylation. However, the role of acetylation in primary cilia regulation remains unclear.

Purpose: Although the lens undoubtedly plays a major role in presbyopia, altered lens function could be in part secondary to age-related changes of the ciliary muscle. Ciliary muscle changes with accommodation have been quantified using optical coherence tomography, but so far these studies have been limited to quantifying changes in ciliary muscle thickness, mostly at static accommodative states. Quantifying ciliary muscle thickness changes does not effectively capture the dynamic anterior-centripetal movement of the ciliary muscle during accommodation.

Identification of lens-regulated genes driving anterior eye development and eye size.

Signals from the lens regulate multiple aspects of eye development, including establishment of eye size, patterning of the presumptive iris and ciliary body in the anterior optic cup and migration and differentiation of neural crest cells. To advance understanding of the molecular mechanism by which the lens regulates eye development, we performed transcriptome profiling of embryonic chicken retinas after lens removal. Genes associated with nervous system development were upregulated in lens-removed eyes, but the presumptive ciliary body and iris region did not adopt a neural retina identity following lens removal.

Background: Cutaneous melanoma is the leading cause of death from cutaneous malignancy and tends to metastasize lymphatically and hematogenously to the lung, liver, brain, and bone; it is a rare source of metastatic disease to the eye. Herein we provide a case report of cutaneous melanoma metastatic to the ciliary body and choroid involving clinical examination, slit lamp photography, and B-scan ultrasonography.

Result: A 55-year-old female with known metastatic cutaneous melanoma presented with pain, a large ciliochoroidal mass, visual decline, and diffuse intraocular inflammation.

Purpose: To evaluate dynamic changes in ciliary parameters and Implantable Collamer Lens V4C (ICL) (STAAR Surgical) haptic position using mydriatic and miotic agents and their effects on the central and peripheral vault.

Methods: This study involved 80 eyes from 40 consecutive patients (mean age: 28.05 years; range: 19 to 42 years) examined 3 months after ICL implantation.
