This image serial demonstrates a patient with simple ectopia lentis. Anterior segment photographs in the upper panel demonstrate nasally subluxated crystalline lenses. Widefield fundus photography shows a "pseudo-buckle" which is the result of an optical effect due to the lens subluxation (artifactual image enlargement). Also note the juvenile macular reflex in this young patient. Ectopia lentis can present isolated ("simple") or in combination with various systemic defects (Marfan's syndrome, Weil-Marchesani syndrome or Ehlers-Danlos syndrome to name a few). Isolated ectopia lentis can be hereditary and causative genes have been identified as ADAMTSL4 located on chromosome 4 and FBN1 gene located on chromosome 15. Defects in the genes cause weakness in the zonular fibers which can lead to lens dislocation. Lastly, various ocular disorders such as Aniridia, Axenfeld-Rieger, Pseudoexfoliation or Trauma may also result in lens dislocation or subluxation.

Inferior temporal retinoschisis extending posteriorly to arcade. The vertical cut shows more severe splitting inferiorly, with visibly attached outer layer. The “inverted V” shape of the inner layer on the left of the image is artifact, due to OCT-algorithm related inversion as this layer extends towards the vitreous.

Condition/keywords: bullous retinoschisis, inferotemporal retinoschisis, outer layer breaks

The enucleation specimen in (B) shows an amelanotic, mushroom-shaped, slightly hemorrhagic tumor near the optic nerve (arrow). The shape is due to infiltration of the retina by a rupture of the Bruch membrane. A retinal detachment artifact is present.

Condition/keywords: enucleation, mushroom-shaped

This enucleation specimen shows a heavily pigmented, solid tumor-infiltrating the ciliary body. The tumor infiltrates the left angle, producing secondary glaucoma. Note the dislocation of the lens and the choroidal detachment artifact on the right bottom angle of the image.

Condition/keywords: enucleation, infiltrating ciliary body, tumor

Large tumors displace the lens. Of the 3 locations in the uveal tract, tumors of the ciliary body have the worst prognosis. This enucleation specimen shows a pigmented, bilobed, dome-shaped tumor arising from the ciliary body (arrow). The lens has been removed, and a diffuse, flat retinal detachment artifact is present.

Uveal melanoma is the most common primary eye malignancy in adulthood, occurring mainly after age 60. The uveal tract — composed of the iris, ciliary body, and choroid — can be affected by uveal melanoma. Despite advances in treatment of the primary tumor, metastatic disease occurs in almost half of patients, generally affecting the liver and lungs via hematogenous dissemination of the primary tumor. Tumors have different levels of pigmentation, and some are amelanocytic (nonpigmented). The differential diagnosis for amelanotic choroidal melanoma is metastatic disease. Large tumors displace the lens. Of the 3 locations in the uveal tract, tumors of the ciliary body have the worst prognosis. The enucleation specimen in (A) shows a firm, dome-shaped, deeply pigmented tumor arising from the ciliary body (arrow). The lens has been removed, and a diffuse retinal detachment artifact is present.

This enucleation specimen shows a whitish, thickened area of the neurosensory retina over the head of the optic nerve, corresponding to a mixed retinoblastoma. Snowballlike structures are present in the vitreous chamber overlying the tumor, corresponding to vitreous seeding. A retinal detachment artifact is present.

Condition/keywords: mixed, retinoblastoma

Metastatic disease is the most frequent intraocular malignant tumor. In women, the most common origin is breast cancer. In men, the most common origin is lung cancer. This pupil–optic nerve section shows a whitish tumor with several foci of necrosis (*) occupying the posterior aspect of the choroid. Note the pigment epithelium over the inner surface of the tumor. A serous retinal detachment is present (arrow) with a retinal detachment artifact overlying the tumor and normal choroid. Note the air bubble artifacts in the vitreous cavity. Another artifact, the compression of the eyeball, is present on the right side.

Condition/keywords: breast cancer, foci of necrosis, metastatic adenocarcinoma, tumor

Leiomyoma is a benign, smooth muscle tumor. Ninety percent of cases occur in women. The differential diagnosis includes amelanotic melanoma and nerve sheath tumors. This transversal pupil–optic nerve (PO) section of an enucleation specimen shows a nodular, well-delineated, whitish tumor in the ciliary body. The cut surface shows small foci of hemorrhage without necrosis. The retina partially covers the inner surface of the tumor, and the sclera is not infiltrated. Note the slightly displaced (subluxated) cataractous lens and the choroidal detachment artifact in the right inferior corner.

Condition/keywords: enucleation, leiomyoma, tumor

This enucleation specimen shows a subretinal hematoma (arrow). In addition, a diffuse, flat retinal detachment artifact is present. The lens is cataractous.

This sample was retrieved from a patient with a blind, painful eye. Blind, painful eye may be the end stage of several conditions including glaucoma, retinal detachment, and endophthalmitis, among others. Evisceration specimens are generally submitted in fragments. Different intraocular structures are identifiable: retina, cornea and capsular bag, choroidal tissue, and hematic material.

Condition/keywords: enucleation, evisceration, intraocular structures

55-year-old white female with history of pathologic myopia+, lattice (laser), SB OU (1990s), and dislocated natural lenses OU that had been watched for years. In the fellow eye she developed phacolytic glaucoma and a PPV, PPL was performed. Plan for both eyes are monitoring. I wanted to get a good picture of her lens today with the optos machine, as the other pics had artifact from the lower lid. It worked out well to use a speculum in the left eye. Vision cc is 20/400 J1+ OD and 20/40 J2 OS; aphakic OU; vitreous clear OD; dislocated lens OS (see pic); retinas attached.
