In afferent pathway, there are primary optic neuropathies due direct damage from virus, and secondary ones, caused by opportunistic infections, neoplasms, ischemia, drugs, where presentation varies. ...

Studies of pancreatic cancer in the setting of second primary malignant neoplasms can provide etiologic clues. An international multicenter study was carried out using data from 13 cancer registries with a registration period up to year 2000. Cancer patients were followed up from the initial cancer diagnosis, and the occurrence of second primary malignant neoplasms was compared with expected va...

introduction: until now, many models have been presented for optical study of the human eye. in recent years, surgery on the anterior section of the eye (such as cataract and photo-refractive surgery) has increased, so a study on the optics of the eye and evaluation of vision quality has become more important. material and methods: in this article, some of these models are considered. they incl...

background esophageal, stomach, and colorectal cancers are commonly lethal gastrointestinal tract (git) neoplasms, causing almost two million deaths worldwide each year. some environmental risk factors are acknowledged; however, genetic defects can significantly contribute to predisposition to git cancers. accordingly, recent works have shown that single-nucleotide polymorphisms (snps) within m...

Background & objective:Primary pleural neoplasms are rare entities compared with the pleural involvement by metastatic carcinoma.

As a result of improved treatment and patient survival, ophthalmic complications are now being seen with increasing frequency in AIDS, occurring in up to 75% of patients during the course of the disease. The eye may be involved by an AIDS-related microvasculopathy, which gives rise to cotton wool spots, and by opportunistic infections caused by a wide range of organisms, including cytomegalovir...

vitreous cavity. Strong glial fibrillary acidic protein positivity confirms the diagnosis. Thickening of the vessel walls, perivascular pigment, intralesional cysts, and calcareous deposits (calcospherites) are also detectable. Massive retinal gliosis is characteristically encountered in phthisical eyes after trauma, surgery, or inflammation and in other conditions such as retinopathy of premat...

This paper presents a review of a dog, with a retrobulbar chondrosarcoma, which was admitted for surgery for visible changes in his eye during inspection. Orbital neoplasia in dogs may be primary and secondary. Sixty percent of orbital neoplasia in dogs are primary, ninety percent of which are malignant. Retrobulbar neoplasms are rare and in their early stage represent a diagnostic challenge. C...
