Metastatic Intraocular Tumor Due to Colorectal Adenocarcinoma: Case Report and Literature Review.

Purpose: To describe the clinical and histopathological findings of a case of intraocular metastasis due to colorectal adenocarcinoma and to carry out a literature review.

Case Report: A 64-year-old man with a history of tumor resection due to infiltrating colorectal adenocarcinoma three years previously sought ophthalmological care because of severe ocular pain without response to medical treatment and progressive vision loss in the left eye. On ultrasonographic examination, there was a heterogeneous intraocular choroidal tumor, which occupied approximately 40% of the vitreous cavity, as well as peritumoral serous retinal detachment.

Conjunctival squamous cell carcinoma: prognostic factors for the recurrence and metastasis and clinicopathological characteristics at an oncological hospital in Peru.

Background/aims: Conjunctival squamous cell carcinoma (CSCC) is the most frequent malignant tumour of the conjunctiva, with scarce recurrence and infrequent metastasis. The purpose of this study is to describe the clinical and pathological characteristics of this neoplasm and to identify the prognostic factors for recurrence and metastasis in a cancer hospital in Peru.

Materials And Method: A longitudinal, retrospective study of 176 consecutive patients diagnosed with SCC of the conjunctiva.

Wide-field angiography for diagnosis and follow-up of Eales disease: a case series.

Wide-field angiography enables assessing peripheral areas with better quality and gives greater deep focus, which improves the image periphery. Some studies have proposed the usefulness of these angiographic systems in inflammatory diseases of the retina. However, few studies have evaluated this technique in Eales disease.

Recurrent vitreous hemorrhage secondary to retinal vessel avulsion.

Spontaneous vitreous hemorrhage is a rare entity, present in 7 out of 100,000 inhabitants. It is associated with different pathologies; however, it is rarely reported to be caused by retinal vessel avulsion syndrome. In the present manuscript, we report a case of avulsion of retinal vessels associated with recurrent vitreous hemorrhage managed, at first, by photocoagulation, but due to the several recurrence of bleeding, the patient went into surgical management.

Lymphoid proliferation in Eyelid: A Primary Follicular Lymphoma Case.

Ocular adnexal lymphoma (OAL) constitutes 8% of all extranodal lymphomas, being rare in the eyelids (5-20%). The objective was to report a case of eyelid follicular lymphoma in a young adult woman. A 35-year-old female with swelling in left lower eyelid with development for 2 months.

[Primary orbital cystic tumor: A case of hydatidosis in a child].

Primary orbital cystic tumors caused by Echinococcus granulosus are rare. As this parasite is endemic in Peru, we report the case of a 10-year-old girl from a rural area of Huancavelica, who presented with progressive and irreducible axial proptosis of the right eye and loss of vision. Orbital tomographic images demonstrated a tumor mass with a cystic appearance.

[Neuroretinitis caused by Bartonella henselae: a case with follow up through optical coherence tomography].

The case of a 36 year-old male with neuroretinitis caused by Bartonella henselae is reported, whose periodic follow-up was done through optical coherence tomography (OCT). The onset of this disease was characterized by unilateral low visual acuity (VA), painless, of sudden onset, in the right eye (RE), associated to l febrile symptom. The funduscopic examination showed edema in the posterior pole which extended from the optical disc to the macular region in the RE.
