To introduce the University of California Irvine (UCI) EyeMobile for Children preschool vision screening program and describe the ophthalmic examination results of children who failed screening with the PlusoptiX S12C photoscreener during one school year. Patients and Methods: Children aged 30-72 months were screened with the PlusoptiX using ROC mode 3 during the 2019-2020 school year. Children who failed screening were referred for comprehensive eye examination on the EyeMobile mobile clinic. Presence of amblyopia risk factors (ARFs), amblyopia, and refractive error was determined via retrospective review of records. Amblyopia was defined as unilateral if there was ≥ 2-line interocular difference in the best-corrected visual acuity (BCVA) and as bilateral if BCVA was < 20/50 for children < 4 years old and < 20/40 for children ≥ 4 years old. ARFs were defined using 2021 American Association for Pediatric Ophthalmology and Strabismus (AAPOS) instrument-based screening guidelines. Results: 5226 children were screened during the study period. Of the 546 children who failed screening, 350 (64%) obtained consent and were examined. Mean age of examined children was 4.45 years. Amblyopia was found in 8% of examined children, with unilateral amblyopia seen in 79% of amblyopic subjects. Glasses were prescribed to 246 (70.3%) children. Of the 240 children who received cycloplegic examinations, 43% had hyperopia and 30% had myopia. The positive predictive value (PPV) of the PlusoptiX screening for ARFs in children who received cycloplegic examinations was 70.4%. Conclusion: A significant proportion of Orange County preschoolers with refractive errors and amblyopia have unmet refractive correction needs. The PlusoptiX S12C photoscreener is an adequate screening device for the UCI EyeMobile for Children program, although modification of device referral criteria may lead to increased PPV. Further research is necessary to understand and overcome the barriers to childhood vision care in our community.

Background: Diabetic retinopathy is one of the leading causes of blindness in the world, and its development and progression can be prevented with appropriate glycemic control. The Health Outreach Partnership of EVMS Students (HOPES) Student-Run Free Clinic at Eastern Virginia Medical School (Norfolk, VA) provides both primary care and ophthalmology care to patients from underserved backgrounds. The purpose of this retrospective chart review is to assess whether a student-run free clinic’s primary care and ophthalmology services are effective in preventing the development and progression of diabetic retinopathy. Methods: Inclusion criteria were a diagnosis of Type 2 Diabetes Mellitus (T2DM), two or more HOPES Ophthalmology Clinic appointments separated by at least 4 months between January 2015 and July 2019, and medical management of T2DM by the HOPES Primary Care Clinic. Objective patient data collected were HbA1c, visual acuity, and documented dilated fundus examination findings. Results: There were 174 HOPES Ophthalmology visits and 66 diabetic eye exam appointments in this five-year time period. The average HbA1c for patients at the initial appointment with the Ophthalmology Clinic was 7.77% ± 1.65% and the average HbA1c at the most recent appointment was 7.4% ± 2.28%. Among all patients, there was no statistically significant change in visual acuity in either eye from baseline to the most recent visit. There was no change in fundus examination findings in any of the patients from their initial visit to their most recent visit. Conclusions: The HOPES Clinic has been effective in preventing the development and progression of diabetic retinopathy in its patients who regularly follow up with both the primary care and ophthalmology clinics. This study highlights that a student-run free clinic is capable of making an impact in the community by preventing the development of a potentially blinding disease, but that further strategies to enable consistent patient follow-up are needed.
