Case Report. A 47-year-old man presented with blurred vision in the right eye. Ophthalmoscopic examination showed several placoid, pigmented lesions in the posterior pole and midperiphery of the retina of both eyes. Results. Patient referred a cutaneous malignant melanoma on the back skin removed 6 years ago. A systemic workup revealed multiple metastases in liver and spleen. After an exhaustiv...

CHOROIDAL NEVUS Choroidal nevus (Figure 1), the most common primary intraocular tumor,1 is a benign tumor that arises from melanocytic cells derived from the neural crest. Choroidal nevi are more common in white people, with 4% of the population having at least one.1 Malignant transformation into melanoma is possible; therefore, choroidal nevi should be monitored even though the rate is 1 in 4,...

Choroidal melanoma is one of the most malignant tumors organ vision, development which associated with risk metastasis and possibility death, indicates relevance search application effective methods treatment this pathology. To date, in choroidal melanoma, preference given to organ-preserving aimed at achieving local control over tumor. One promising techniques photodynamic therapy, a method ba...

IMPORTANCE Intraocular lymphomas represent a diverse group of hematologic malignant neoplasms involving different tissues within the eye. Predominant involvement of the retina and vitreous without uveal infiltration in systemic lymphoma, mimicking a primary vitreoretinal lymphoma, is extremely rare. Our study emphasizes the importance of systemic evaluation in addition to central nervous system...

A decreased count of retinal photoreceptors all over the fundus and a loss of retinal pigment epithelium cells mainly in the parapapillary region have been reported to be associated with glaucoma. This study addressed the question whether this cell loss in the deep retinal layers may be connected with a change of the choroidal thickness in glaucomatous eyes. Histological sections of 12 eyes wit...

Choroidal melanoma is the most common primary ocular malignant neoplasm among adults. However, innumerable benign and malignant lesions may mimic its ophthalmoscopic features. Moreover, atypical presentations of the tumor may also occur, in some cases making diagnostic elucidation even more difficult and thus increasing the importance of supplementary tests, especially ultrasonographic methods....
