[Clinico-pathological correlations: posterior compartment of the eye and orbit]

Diseases of the posterior compartment and the orbit are characterised by histological findings, most of which can be reproduced clinically. Examples are the examination of calcifications in retinoblastoma by ultrasonography. In the present review, histological findings of tumour and other diseases of the posterior ocular compartment and the orbit are presented and correlated with the clinical pictures and imaging techniques: uveal melanoma, choroidal nevus, choroidal metastases, choroidal hemangioma, retinoblastoma, Coat's disease, sympathetic ophthalmia, pleomorphic adenoma (benign mixed tumour) of the lacrimal gland, dacryoadenitis, lymphoma, rhabdomyosarcoma, Langerhans cell histiocytosis, orbital metastases, and phthisical eyes. Histopathology is usually the gold standard for a definitive diagnosis. It is very important for residents and those in training to become familiar with clinico-pathological correlations as these provide insight in pathophysiological processes. Regarding ophthalmic surgery, ophthalmic pathology offers the possibility to study wound healing and complications. A close collaboration between clinicians and ocular pathologists allows for an optimised processing of the submitted tissue and diagnosis. Thus, pre- and postoperative care can also be improved. This outstanding knowledge that ophthalmologists have gained over the last decades and beyond, should be preserved and passed on to the next generations in order to maintain a high standard in ophthalmological care.
