Applications of the Polymerase Chain Reaction to Diagnosis of Ophthalmic Disease☆

Abstract 

The polymerase chain reaction (PCR) is a powerful molecular biologic technique for the analysis of very small amounts of DNA. This technique has found increasing use in the past 10 years for the detection of pathogenic organisms associated with many forms of ocular inflammatory and infectious disease. PCR has shown utility in the diagnosis of viral uveitis, infectious endophthalmitis, and parasitic eye disease. The strengths and weaknesses of this diagnostic technique are discussed. Additionally, uses of PCR in linking known pathogens to disease, and to discovering novel pathogens, are addressed.
