Abstract: : Indiana University has developed an Optometric teaching clinic and continues humanitarian missions in the city and state of Guanajuato, Mexico. The state of Guanajuato has a population of approximately 5 million people with 49% without insurance and full under the care of the Department of Infants and Families. Purpose: To report the prevalence of pathology in the population that was examined in two recent missions to Guanajauto Mexico. Methods: The 6860 patients seen on the two trips were review. Data on symptoms, signs and diagnoses were tabulated. Tables were developed with as much specificity as possible. Typical data for refractive errors and presbyopia was presented previously and will not be included in this report Results: In addition to distance and near blur, around 50% of the patients complained about red eyes and/or headache. The prevalence of detailed signs was organized by nine anatomical categories including orbit and lacrimal, lids, cornea, conjuctiva, uvea, lens, vitreaous, optic disk and retina. For the nine categories, the number of patients that presented with signs listed in descending order was the conjunctiva (2097 patients with 1846 patients having pterygium), lens (mostly 1716 patients with cataract) and cornea (749 patients) were the categories with the most positive findings. Retinal signs were found in 331 patients and lid problems were found in 166 patients. A very small number of patients had signs in the orbit, uveal tract or vitreous categories. When the assessments for each patient were reviewed, the most common categories of ocular diagnoses were anterior eye infections (e.g. bacterial or other types of conjuctivits), strabismus and neurological conditions. Glaucoma was only found in 46 patients. The most common systemic diseases were hypertension (1361 patients) and Diabetes Mellitus (648 patients). Conclusions: There are a large variety of pathologies seen in this population that could be more effectively utilized for clinical training of our students.
