Glaucoma Related to Ocular and Orbital Tumors Sonal P
Chapter Glaucoma Related to Ocular and Orbital Tumors Sonal P. Yadav Abstract Secondary glaucoma due to ocular and orbital tumors can be a diagnostic challenge. It is an essential differential to consider in eyes with a known tumor as well as with unilateral, atypical, asymmetrical, or refractory glaucoma. Various intraocular neoplasms including iris and ciliary body tumors (melanoma, metasta- sis, lymphoma), choroidal tumors (melanoma, metastasis), vitreo-retinal tumors (retinoblastoma, medulloepithelioma, vitreoretinal lymphoma) and orbital tumors (extra-scleral extension of choroidal melanoma or retinoblastoma, primary orbital tumors) etc. can lead to raised intraocular pressure. The mechanisms for glaucoma include direct (tumor invasion or infiltration related outflow obstruction, tra- becular meshwork seeding) or indirect (angle closure from neovascularization or anterior displacement or compression of iris) or elevated episcleral venous pressure secondary to orbital tumors. These forms of glaucoma need unique diagnostic techniques and customized treatment considerations as they often pose therapeutic dilemmas. This chapter will review and discuss the mechanisms, clinical presenta- tions and management of glaucoma related to ocular and orbital tumors. Keywords: ocular tumors, secondary glaucoma, orbital tumors, angle infiltration, neovascular glaucoma, neoplastic glaucoma 1. Introduction With the advent of constantly evolving and advancing ophthalmic imaging tech- niques as well as surgical modalities in the field of ophthalmic diseases, diagnostic accuracy, and treatment outcomes of ocular as well as orbital tumors have improved remarkably over the past few years. Raised intraocular pressure (IOP) is known to be one of the presenting features or associated finding for numerous ocular as well as orbital tumors. Ocular and orbital tumors can cause secondary glaucoma due to various mechanisms. -

Downloaded from British Journal of Ophthalmology, 1977, 61, 229-232 Medulloepithelioma (diktyoma) presenting as a perforated, infected eye MOHAMED A. VIRJI Central Pathology Laboratory, Ministry of Health, Dar-es-Salaam, Tanzania SUMMARY A case of embryonal medulloepithelioma (diktyoma) presenting with perforated infected eye in a 13-year-old Black African girl is described. The tumour mass occupied most of the deformed eye, and invasion of the sclera anteriorly was seen. There was no evidence of orbital or distant tumour involvement. It is suggested that with increasing age these tumours are more likely to show frankly malignant features. Medulloepithelioma (diktyoma) is a rare neoplasm anteriorly perforated left eye, with loss of cornea, of the eye which is characterised by slow growth and purulent discharge, and a fragmenting mass of local invasion and is composed of glandular, irregular brownish-grey tissue attached mainly to neural, and mesenchymal elements (Andersen, the superior and temporal portion of the eye and 1962). It presents even rarely as an infected perfor- extending into the posterior chamber. The infection ated eye with a fungating mass replacing the ocular was controlled with systemic antibiotics and the left copyright. contents.

ICO Residency Curriculum 2nd Edition and Updated Community Eye Health Section The International Council of Ophthalmology (ICO) Residency Curriculum offers an international consensus on what residents in ophthalmology should be taught. While the ICO curriculum provides a standardized content outline for ophthalmic training, it has been designed to be revised and modified, with the precise local detail for implementation left to the region’s educators.

International Council of Ophthalmology Residency Curriculum Introduction “Teaching the Teachers” The International Council of Ophthalmology (ICO) is committed to leading efforts to improve ophthalmic education to meet the growing need for eye care worldwide. To enhance educational programs and ensure best practices are available, the ICO focuses on "Teaching the Teachers," and offers curricula, conferences, courses, and resources to those involved in ophthalmic education. By providing ophthalmic educators with the tools to become better teachers, we will have better-trained ophthalmologists and professionals throughout the world, with the ultimate result being better patient care. Launched in 2012, the ICO’s Center for Ophthalmic Educators, educators.icoph.org, offers a broad array of educational tools, resources, and guidelines for teachers of residents, medical students, subspecialty fellows, practicing ophthalmologists, and allied eye care personnel. The Center enables resources to be sorted by intended audience and guides ophthalmology teachers in the construction of web-based courses, development and use of assessment tools, and applying evidence-based strategies for enhancing adult learning. -
Successful Treatment of Ciliary Body Medulloepithelioma with Intraocular
Stathopoulos et al. BMC Ophthalmology (2020) 20:239 https://doi.org/10.1186/s12886-020-01512-y CASE REPORT Open Access Successful treatment of ciliary body medulloepithelioma with intraocular melphalan chemotherapy: a case report Christina Stathopoulos*, Marie-Claire Gaillard, Julie Schneider and Francis L. Munier Abstract Background: Intraocular medulloepithelioma is commonly treated with primary enucleation. Conservative treatment options include brachytherapy, local resection and/or cryotherapy in selected cases. We report for the first time the use of targeted chemotherapy to treat a ciliary body medulloepithelioma with aqueous and vitreous seeding. Case presentation: A 17-month-old boy with a diagnosis of ciliary body medulloepithelioma with concomitant seeding and neovascular glaucoma in the right eye was seen for a second opinion after parental refusal of enucleation. Examination under anesthesia showed multiple free-floating cysts in the pupillary area associated with iris neovascularization and a subluxated and notched lens. Ultrasound biomicroscopy revealed a partially cystic mass adjacent to the ciliary body between the 5 and 9 o’clock meridians as well as multiple nodules in the posterior chamber invading the anterior vitreous inferiorly. Fluorescein angiography demonstrated peripheral retinal ischemia. Left eye was unremarkable. Diagnosis of intraocular medulloepithelioma with no extraocular invasion was confirmed and conservative treatment initiated with combined intracameral and intravitreal melphalan injections given according to the previously described safety-enhanced technique. Ciliary tumor and seeding totally regressed after a total of 3 combined intracameral (total dose 8.1 μg) and intravitreal (total dose 70 μg) melphalan injections given every 7–10 days. Ischemic retina was treated with cryoablation as necessary. -

SHRIKHANDE, AND M. B. SAMPAT Department of Pathology, Tata Memorial Hospital, Bombay, India A medullo-epithelioma (diktyoma) is a rare malignant tumour of the eye which arises from the unpigmented epithelium of the ciliary body; diktyoma of the optic nerve with intercranial extension has also been described (Reese, I963). The name diktyoma was given by Fuchs ( I908) to indicate the net-like appearance of the tumour. We have found fifty examples of diktyoma of the ciliary body, most of them in the German literature. Three cases have been reported from India (Kesavachar and Junnarkar, I960; Nirankari, Gulati, and Chaddah, I960; Shivde, Kher, and Junnarkar, I969). The case reported below is the first to be seen at the Tata Memorial Hospital, Bombay, during the last 30 years. copyright. Case report A Hindu male child aged 5 years had shown enlargement of the right eyeball for 3 weeks. There was no history of pain or of any past major illness. He was the third child, the other children being healthy and normal. http://bjo.bmj.com/ Examination The right eyeball was found to be enlarged, with dilated capillaries over the sclera.
