PURPOSE: The definitive identification of ocular pathogens optimizes effective treatment. Although the types of ocular pathogens are known; there is less definitive information on the prevalence of causative infections including viruses, fungi, and protozoa, which is the focus of this retrospective laboratory review. METHODS: Data used for laboratory certification were reviewed for the detection of bacteria, viruses, fungi, and protozoa, from patients with infectious keratitis, endophthalmitis, and conjunctivitis. The main outcome parameter was laboratory-positive ocular infection. RESULTS: The distribution of infectious agents for keratitis (n=1,387) (2004-2018) was bacteria 72.1% (Staphylococcus aureus 20.3%, Pseudomonas aeruginosa 18%, Streptococcus spp. 8.5%, other gram-positives 12.4%, and other gram-negatives 12.9%), Herpes simplex virus 16%, fungi 6.7%, and Acanthamoeba 5.2%. For endophthalmitis, (n=770) (1993-2018), the bacterial distribution was coagulase-negative Staphylococcus 54%, Streptococcus spp. 21%, S. aureus 10%, other gram-positives 8%, and gram-negatives 7%. The distribution for conjunctivitis (n=847) (2004-2018) was Adenovirus 34%, S. aureus 25.5%, Streptococcus pneumoniae 9%, Haemophilus 9%, other gram-negatives 8.8%, other gram-positives 6%, coagulase-negative Staphylococcus 4.5% and Chlamydia 3.2%. CONCLUSION: An updated monitoring of ocular pathogens creates an awareness of the different infectious etiologies and the importance of laboratory studies. This information can determine treatment needs for infectious ocular diseases.
