Background: Ciliary body tumors can remain undetected and achieve large dimensions. Pigmented ciliary body tumors include: melanoma, leiomyoma and melanocytoma, however correct diagnosis may require tissue diagnosis with immunohistochemical stains.
Case Presentation: Two men presented with identical ciliochoroidal tumors. Both had darkly pigmented dome-shaped anterior uveal masses, exudative retinal detachments and transillumination shadowing. Ocular PET-CT imaging revealed that both were metabolically active consistent with a diagnosis of cancer. However, immunohistochemical examination revealed one a leiomyoma and the other melanoma.
Conclusion: Uveal leiomyoma can be an indistinguishable doppelgänger to ciliochoroidal melanoma, where the diagnosis can only be established by immunohistopathology.

Topical brinzolamide-induced ciliary body effusion with secondary angle closure and myopic shift.

Here, we describe a rare case of drug-induced unilateral ciliary body effusion precipitated by topical brinzolamide, presenting acutely with pain, angle closure and myopic shift.Ciliary body effusion was suspected clinically and confirmed by ultrasound biomicroscopy. Brinzolamide was ceased, atropine instilled and the ciliary body effusion promptly resolved without need for further treatment.

Objective: Ciliary body medulloepithelioma (CBME), a pediatric intraocular tumor with potential for locally aggressive behavior and metastasis, may present with a diverse spectrum of clinical and histopathologic features leading to diagnostic and management challenges. Examination of unusual CBME cases highlights challenges and modern diagnostic techniques which facilitate accurate diagnosis and guide management.
Methods: A retrospective clinicopathologic analysis of 6 patients with unusual clinical or pathologic features of CBME was performed.

Cilia assembly and function rely on the bidirectional transport of components between the cell body and ciliary tip via Intraflagellar Transport (IFT) trains. Anterograde and retrograde IFT trains travel along the B- and A-tubules of microtubule doublets, respectively, ensuring smooth traffic flow. However, the mechanism underlying this segregation remains unclear.

Pseudoexfoliation syndrome (PXS) is an age-related fibrillopathy where fibrillar exfoliation material accumulates and deposits in ocular and extra-ocular tissue. Within the eye, this substance accumulates on the ocular surface and in the anterior segment of the eye, impacting ocular structures such as the conjunctiva, Tenon's capsule, sclera, cornea, iris, ciliary body, trabecular meshwork, and lens. This review aims to collate the current literature on how each anatomical part of the eye is affected by PXS, with a strong focus on molecular changes.
