Most intraocular tumors are reliably diagnosed based on the clinical evaluation or with noninvasive diagnostic techniques. However, accurately diagnosing a small percentage of tumors can be challenging. A tissue biopsy is thus needed to establish a definitive diagnosis and plan the requisite treatment. From fine-needle aspiration biopsy (FNAB) to surgical excision, all tissue collection techniques have been studied in the literature. Each technique has its indications and limitations. FNAB has been reported to provide for 88-95% reliable and safe ophthalmic tumor diagnosis and has gained popularity for prognostic purposes and providing eye conserving treatment surgeries. The technique and instrumentation for biopsy vary depending upon the tissue involved (retina, choroid, subretinal space, vitreous, and aqueous), suspected diagnosis, size, location, associated retinal detachment, and clarity of the media. The cytopathologist confers a very important role in diagnosis and their assistance plays a key role in managing and planning the treatment for malignancies.}, URL ={https://journals.lww.com/ijo/pages/default.aspx/article.asp?issn=0301-4738;year=2016;volume=64;issue=6;spage=415;epage=421;aulast=Rishi;t=6}, eprint ={https://journals.lww.com/ijo/pages/default.aspx/article.asp?issn=0301-4738;year=2016;volume=64;issue=6;spage=415;epage=421;aulast=Rishi;t=6} }
