RESUMO
PURPOSE: To study the correlation between corneal and scleral intraocular pressure (IOP) by pneumatonometry in pediatric patients. DESIGN: Cross-sectional study. PARTICIPANTS: Patients (age range, 0-15 years) undergoing an eye examination under anesthesia or eye surgery were recruited at the University of California, San Francisco, Benioff Children's Hospital between July 2015 and April 2016. METHODS: Intraocular pressure measurements were obtained by pneumatonometry on the central cornea and the inferonasal and inferotemporal sclera in a random order. Spearman correlations between corneal versus inferonasal scleral IOP and corneal versus inferotemporal scleral IOP were calculated. A linear mixed-effect model was used to derive a predictive equation for corneal IOP from scleral IOP and to perform covariate analysis for age, axial length, central corneal thickness, and lens status. The standard deviation of the predicted corneal IOP was determined by bootstrap mixed-effect regression analysis. MAIN OUTCOME MEASURES: The predictive model of corneal IOP from scleral IOP. RESULTS: Seventy-five eyes from 40 patients were included in the study. Spearman correlation coefficient for corneal versus inferotemporal scleral IOP was 0.79 (P < 0.01) and 0.48 for corneal versus inferonasal scleral IOP (P < 0.01). Corneal IOP may be predicted from scleral IOP via the following equations: corneal IOP = 0.73 × inferotemporal scleral IOP + 7.45 and corneal IOP = 0.21 × inferonasal scleral IOP + 17.83. Central corneal thickness (P = 0.07), lens status (P = 0.4), age (P = 0.33), and axial length (P = 0.15) did not affect significantly the relationship between corneal and scleral IOP in the multivariate regression analysis. The standard deviation of predicted corneal IOP was less than 1.2 mmHg within an inferotemporal scleral IOP range of 10 to 35 mmHg. CONCLUSIONS: In children, corneal and scleral IOP are correlated significantly when measured by pneumatonometry. Measurements obtained from the inferotemporal sclera are better predictors of corneal IOP than those obtained from inferonasal sclera. Pneumatonometry on the inferotemporal sclera may be an alternative method to estimate IOP for pediatric patients from whom corneal IOP measurement is difficult to obtain.

The authors describe, for the first time to their knowledge, a case of a congenital macrocystic lymphatic malformation of the orbit with associated venous stasis retinopathy that acutely normalized after drainage and sclerotherapy of the lesion. Prenatal ultrasound revealed prominence of the left orbital soft tissue, and at birth, the patient was noted to have unilateral proptosis, tortuous retinal vessels, and intraretinal hemorrhages in all 4 quadrants in the left eye. MRI demonstrated a primarily intraconal, multiloculated, T2-hyperintense mass consistent with a lymphatic malformation. Ultrasound-guided cyst aspiration and sclerotherapy was performed, with subsequent improvement of the proptosis and resolution of the vessel tortuosity and intraretinal hemorrhages. Although venous stasis retinopathy is usually related to central retinal vein occlusion or carotid artery occlusive disease, any entity that increases orbital venous resistance can generate retinal venous dilation and intraretinal hemorrhages, including an orbital lymphatic malformation.

Improving access to comfortable and well-fitting glasses for children with craniofacial differences may improve their visual outcomes. The purpose of this study was to describe challenges in spectacle fitting facing patients with frontonasal dysplasia and to report successful methods for creating custom 3D designed glasses. Additionally, the process of systematically collecting and analyzing spectacle-fitting challenges can inform future processes of automated design of 3D printed glasses and can be applied to other specific craniofacial syndromes.

PURPOSE: To compare outcomes and complications of three surgical techniques for the treatment of congenital dacryocystoceles: nasolacrimal probing and irrigation (P+I), P+I plus nasal endoscopy (NE) with intranasal cyst marsupialization, and primary NE with intranasal cyst marsupialization. METHODS: The medical records of children ≤2 years of age at a single academic center with a diagnosis of dacryocystocele from 2012 to 2022 were retrospectively identified and reviewed. The primary outcome was resolution of the dacryocystocele (ie, elimination of the medial canthal mass and resolution of tearing or discharge) after a single procedure ("primary success"). Surgical techniques were compared using exact logistic regression. RESULTS: Of 54 patients, 21 (39%) underwent P+I, 23 (43%) underwent P+I plus nasal endoscopy, and 10 (18%) underwent primary NE. Primary success was 76% for P+I and 100% for the other two cohorts. Most patients (89%) who underwent P+I received general anesthesia compared with none who underwent primary nasal endoscopy. Most complications were related to the use of general anesthesia, with a complication rate of 10% for P+I, 48% for P+I plus NE, and 0% for primary NE. Most P+I procedures required hospital admission compared to half of primary NE procedures. CONCLUSIONS: In our study cohort, primary NE provided good outcomes and was associated with a lower complication rate than P+I with or without NE.

OBJECTIVE: To examine the relationship between the cause or severity of hypotension and the development of severe ROP (sROP) (≥stage 3 or stage 2 with plus disease in zone I or II). STUDY DESIGN: Infants (<28 weeks' gestation, n = 242) were observed for hypotension and treated with a standardized hypotension-treatment protocol. Hypotension was classified as resulting from one of the following causes: (1) culture-positive infection and/or necrotizing enterocolitis; (2) patent ductus arteriosus ligation; or (3) "idiopathic" (no cause identified other than prematurity), and as being either dopamine responsive or dopamine resistant. Cortisol levels were measured for infants with dopamine-resistant hypotension. Eye examinations were performed until the retinopathy of prematurity resolved or the vasculature matured. Multivariable logistic regression analysis was performed to determine the relationship between the cause/severity of hypotension and sROP. RESULTS: Overall, 66% of infants developed hypotension (41% were dopamine responsive and 25% were dopamine resistant). sROP developed in 19% of infants. "Idiopathic" dopamine-resistant hypotension was the only cause significantly related to sROP. Of the infants with dopamine-resistant hypotension, 66% had low serum cortisol (≤10 µg/dL). Low cortisol, in the presence of dopamine-resistant hypotension, was significantly associated with sROP and accounted for the relationship between "idiopathic" hypotension and sROP. When low cortisol was included in statistical models, other known risk factors, such as immature gestation, were no longer significantly related to sROP. CONCLUSION: Low cortisol, in the presence of dopamine-resistant hypotension, has the greatest magnitude of association with sROP.

Childhood cataract is a complex condition requiring longitudinal care, including early diagnosis, timely referral to a specialist, early surgical intervention, and dedicated postoperative care. Adherence to refractive correction and amblyopia therapy are critical for visual rehabilitation, even months to years after the cataract is removed. We review the impact of the social determinants of health on each step in the visual rehabilitation pathway for children with congenital and infantile cataracts. Children from socioeconomically marginalized backgrounds are more likely to experience delays in access to care and utilization of surgical services. They are also less likely to adhere to amblyopia therapy, with corresponding decrements in visual outcomes. Additional sociocultural factors, including parental stress, self-efficacy, and health literacy, pose barriers for these children. Standardizing clinical roles, improving health communication, managing parental stress, and implementing systemic policy changes may alleviate socioeconomic disparities in outcomes for children with cataracts.

PURPOSE: To describe a case of primary coenzyme Q10 deficiency in a child manifesting as early-onset renal failure, retinal dystrophy, and optic atrophy leading to progressive vision loss. METHODS: Clinical presentation and workup including visual fields, electroretinogram, and optical coherence tomography are presented. Genetic testing was performed. RESULTS: An eight-year-old female with nephropathy requiring renal transplantation subsequently developed progressive cone-rod dystrophy and optic atrophy. The patient had negative results on a targeted next-generation sequencing retinal dystrophy panel but whole-exome sequencing revealed two variants in COQ2 (likely biallelic), consistent with a diagnosis of primary coenzyme Q10 deficiency. CONCLUSIONS: Primary coenzyme Q10 deficiency is a rare disorder with variable systemic and ocular findings; there is also genetic heterogeneity. Genetic testing aids in the diagnosis of this condition, and variants in the COQ2 and PDSS1 genes appear to have the strongest association with ocular manifestations. Oral supplementation of coenzyme Q10 may slow progression of disease. This case highlights the utility of whole-exome sequencing in the diagnosis of a rare syndromic form of ocular disease and reports a novel phenotypic association for this condition.

PURPOSE: To investigate factors associated with spectacle wear among low-income preschoolers who receive glasses through the See Well to Learn (SWTL) program. METHODS: Qualitative study of parental perceptions of factors contributing to compliance during a longitudinal study of eyeglass wear utilizing thematic analysis of a series of three scripted phone calls during the 2017-2018 school year. Participants were parents of 164 children ages 3-5, from 51 Head Start preschools in the greater San Francisco region. RESULTS: A total of 470 scripted parental telephone calls were successfully completed during the study period. Six major themes affecting glasses compliance in this group were identified including: (1) awareness of need and noted visual improvement; (2) continuous efforts to improve compliance by working with parent; (3) collaborative efforts between home and school such as parent-teacher encouragement; (4) child comfort and eyewear preferences; (5) the importance of two functional pairs of eyewear to achieve full-time wear; and (6) coordination of care offered by the SWTL program. CONCLUSIONS: This study offers insight into factors contributing to child eyewear compliance during critical years of vision development. These findings offer lessons to improve compliance and identify a need to adjust California's current policies on vision coverage for children.

Purpose: To report a case of congenital ciliary body cysts causing microspherophakia, ectopia lentis, and secondary angle closure glaucoma in an infant. Observations: A 16-month-old male was found to have bilateral ciliary body cysts associated with zonular laxity or absence causing microspherophakia and ectopia lentis as demonstrated on multimodal imaging. Additionally, the patient had secondary angle closure glaucoma which was likely multi-factorial related to both lens abnormalities and anterior displacement of the iris from the cysts themselves. The patient underwent lensectomy and cyst removal which resulted in intraocular pressure stabilization and visual rehabilitation. Conclusions and Importance: Congenital ciliary body cysts are a rare cause of lens abnormalities and secondary angle closure glaucoma in children. Information regarding genetic underpinnings or systemic associations is limited.
RESUMO
Importance: Finding a suitable fit in glasses for pediatric patients with congenital and acquired craniofacial abnormalities is difficult; consequently, these children are at high risk of vision loss secondary to refractive amblyopia as they often have poor adherence to daily glasses wearing. Custom 3-dimensional (3D)-printed glasses may have an improved design and fit, but access is limited by the availability of computed tomography and magnetic resonance imaging (MRI). Objective: To describe a method for using a commercially available smartphone 3D surface imaging (3DSI) technique to capture facial anatomy as a basis for custom glasses design. Design, Setting, and Participants: This quality improvement study analyzes data from a case series in a primary academic center with multiple referral centers throughout the United States. The evaluation included reported fit descriptions from patients with poor glasses adherence due to craniofacial abnormalities. Main Outcomes and Measures: Key anatomic parameters for glasses fit (face width, distance from ear bridge to nasal bridge, distance from center of pupil to center of nasal bridge, distance from lateral to medial canthus, ear vertical offset, and nasal bridge width) were compared between scans. A 3DSI scan was considered successful if these key parameters could be determined and the difference in measurements was less than 5% between MRI and 3DSI. A second outcome measure included the fit of glasses designed by the 3DSI method as reported by the patient, parent, or guardian. Results: Measurements of key parameters for glasses fit were similar across MRI and 3DSI scans with a mean (SD) difference of 1.47 (0.79) mm between parameters (range, 0.3-4.60 mm). Among 20 patients aged 1 to 17 years with craniofacial abnormalities, all achieved a successful fit (reporting daily glasses adherence without irritation) as judged by the patient, parent, or guardian. A mean of 1.7 revisions were made from initial prototype to final frame production using 3DSI technology. Conclusions and Relevance: This study demonstrated that smartphone-enabled 3DSI coupled with widely available 3D printing technology can produce custom frames with a successful fit for patients with craniofacial anomalies. This accessible and well-tolerated imaging process may have implications for adherence with glasses wearing among patients at risk of vision loss due to amblyopia.

A two-year-old full-term boy with a history of an intermittent exotropia presented to the pediatric ophthalmology clinic for routine follow-up. He was found to have a stable sensorimotor examination however dilated funduscopic examination of the right eye was significant for a dim foveal reflex with a new discrete, white, elevated retinal lesion superotemporal to the fovea with surrounding subretinal exudates. An examination under anesthesia (EUA) was performed two days later that revealed a subretinal posterior pole granuloma with hyperfluorescence and late leakage from the lesion without telangiectatic vessels on fluorescein angiography. A repeat EUA one month later demonstrated an increase in surrounding subretinal and overlying intraretinal fluid. The patient was started on topical 1% prednisolone with a presumed diagnosis of Toxocara granuloma. At EUA, three months later, the subretinal and intraretinal fluid had resolved. The topical steroids were tapered, and the patient continues to be followed closely.

To describe a case of chronic granulomatous disease (CGD) with ocular lesions as the presenting findings. An ocular examination of a 4-month-old male infant with poor vision revealed punched-out macular and perivascular chorioretinal fibrosis and atrophy with peripheral retinal nonperfusion. Subsequently, he was hospitalized for recurrent infections and was diagnosed with CGD. Repeated examination demonstrated enlargement of the chorioretinal lesions without evidence of active inflammation or neovascularization. CGD causes recurrent, severe, life-threatening infections in children and should be considered in the differential diagnosis of chorioretinal lesions with peripheral retinal nonperfusion.

BACKGROUND: The antiepileptic medication vigabatrin has been associated with ocular toxicity, and close ophthalmic monitoring has been recommended; however, there is no clear consensus regarding the value and feasibility of such monitoring in children. We describe ophthalmic assessments in children in a real-world clinical setting, the incidence of vigabatrin-related ocular toxicity, and the utility of regular screening or ancillary testing in children taking vigabatrin. METHODS: The medical records of children taking vigabatrin with one or more ophthalmic assessments at Children's Hospital of Philadelphia or University of California, San Francisco, between May 2010 and May 2021, were reviewed retrospectively. Abnormalities on ophthalmic examination, visual field (VF), electroretinogram (ERG), and optical coherence tomography (OCT) were reviewed and categorized as attributable to vigabatrin, possibly attributable to vigabatrin, or not attributable to vigabatrin. RESULTS: A total of 1,281 assessments of 284 children (mean age, 2.09 years) were included. Of these, 283 (99.6%) had funduscopic examination(s), 37 (13.0%) had ERG, 19 (6.7%) had OCT, and 6 (2.1%) had formal VF. Rate of examinations and ERGs per child decreased over the 10-year study period. Two children (0.7%) had definite vigabatrin-related ocular toxicity, both identified on ERG. An additional 4 children (1.4%) had optic atrophy of unclear relation to vigabatrin, categorized as possible toxicity. The remaining 278 children did not have abnormal examination or testing findings attributable to vigabatrin. CONCLUSIONS: The incidence of vigabatrin-related ocular toxicity in children was low in our cohort. Ocular and neurologic comorbidities and limited examinations in children make identification of such toxicity challenging and the value of screening is unclear.

Purpose Physician diversity is limited in ophthalmology and oculofacial plastic surgery. Determination of barriers within the application process for oculofacial plastic surgery may help target efforts to improve the recruitment of underrepresented groups. This study aimed to illuminate perceived barriers to increasing diversity in oculofacial plastic surgery trainees, according to the American Society of Ophthalmic Plastic and Reconstructive Surgery (ASOPRS) fellows and fellowship program directors (FPDs). Methods During the month of February 2021, we sent surveys out to 54 current oculofacial plastic surgery fellows and 56 FPDs at 56 oculofacial plastic surgery programs recognized by the ASOPRS nationwide using a 15-question Qualtrics survey. Results Sixty-three individuals (57%) responded to the survey: 34 fellows (63%) and 29 FPDs (52%). Eighty-eight percent of fellows and 68% of FPDs identified as non-underrepresented in medicine (UiM). Forty-four percent of fellows and 25% of FPDs identified as men. FPDs most commonly noted, "Not enough minorities applying to our program" and "The objective data (Ophthalmic Knowledge Assessment Program score, United States Medical Licensing Examination Step scores, clinical honors, Alpha Omega Alpha status, letter of recommendation) for minority applicants often do not meet the threshold required to offer an interview or to be ranked to match" as barriers. Among fellows, the lowest-rated considerations when applying to oculofacial plastic surgery were "Racially/ethnically diverse faculty" and "Perceptions of minority candidates by fellowship programs," whereas "Likelihood of matching in program of choice" was ranked highest in considerations. Fellows identifying as men indicated greater concern for "Financial factors related to fellowship (e.g., loans, salary, cost of living, or cost of interviewing)" compared to fellows identifying as women who noted greater concern for "Program or preceptor acceptance of starting or having a family during fellowship." Conclusion Responses from FPDs suggest that efforts focused on recruiting and supporting diverse students to medicine and ophthalmology, mentoring applicants interested in oculofacial plastic surgery, and restructuring the application process to decrease bias, may improve diversity within the subspecialty. The lack of UiM representation in this study, 6% fellows and 7.4% FPDs identified as UiM, shows both the stark underrepresentation and the need for further research into this topic.
RESUMO
BACKGROUND: As instrument-based pediatric vision screening technology has evolved, the American Association for Pediatric Ophthalmology and Strabismus (AAPOS) has developed uniform guidelines (2003, updated 2013) to inform the development of devices that can detect specified target levels of amblyopia risk factors (ARFs) and visually significant refractive error. Clinical experience with the established guidelines has revealed an apparent high level of over-referral for non-amblyopic, symmetric astigmatism, prompting the current revision. METHODS: The revised guidelines reflect the expert consensus of the AAPOS Vision Screening and Research Committees. RESULTS: For studies of automated screening devices, AAPOS in 2021 recommends that the gold-standard confirmatory comprehensive examination failure levels include anisometropia >1.25 D and hyperopia >4.0 D. Astigmatism >3.0 D in any meridian and myopia < -3 D should be detected in children <48 months, whereas astigmatism >1.75 D and myopia < -2 D should be detected after 48 months. Any media opacity >1 mm and manifest strabismus of >8Δ should also be identified. Along with performance in detecting ARFs and refractive error, validation studies should also report screening instrument performance with regard to presence or absence of amblyopia. Instrument receiver operating characteristic curves and Bland-Altman analysis are suggested to improve comparability of validation studies. CONCLUSIONS: Examination failure criteria have been simplified and the threshold for symmetric astigmatism raised compared to the 2013 guidelines, whereas the threshold for amblyogenic anisometropia has been decreased. After age 4 years, lower magnitudes of symmetric astigmatism and myopia are also targeted despite a low risk of amblyopia, because they can influence school performance and may warrant consideration of myopia prevention therapy.

IMPORTANCE: Cataract is an important cause of visual impairment in children. Data from a large pediatric cataract surgery registry can provide real-world estimates of visual outcomes and the 5-year cumulative incidence of adverse events. OBJECTIVE: To assess visual acuity (VA), incidence of complications and additional eye operations, and refractive error outcomes 5 years after pediatric lensectomy among children younger than 13 years. DESIGN, SETTING, AND PARTICIPANTS: This prospective cohort study used data from the Pediatric Eye Disease Investigator Group clinical research registry. From June 2012 to July 2015, 61 eye care practices in the US, Canada, and the UK enrolled children from birth to less than 13 years of age who had undergone lensectomy for any reason during the preceding 45 days. Data were collected from medical record reviews annually thereafter for 5 years until September 28, 2020. EXPOSURES: Lensectomy with or without implantation of an intraocular lens (IOL). MAIN OUTCOMES AND MEASURES: Best-corrected VA and refractive error were measured from 4 to 6 years after the initial lensectomy. Cox proportional hazards regression was used to assess the 5-year incidence of glaucoma or glaucoma suspect and additional eye operations. Factors were evaluated separately for unilateral and bilateral aphakia and pseudophakia. RESULTS: A total of 994 children (1268 eyes) undergoing bilateral or unilateral lensectomy were included (504 [51%] male; median age, 3.6 years; range, 2 weeks to 12.9 years). Five years after the initial lensectomy, the median VA among 701 eyes with available VA data (55%) was 20/63 (range, 20/40 to 20/100) in 182 of 316 bilateral aphakic eyes (58%), 20/32 (range, 20/25 to 20/50) in 209 of 386 bilateral pseudophakic eyes (54%), 20/200 (range, 20/50 to 20/618) in 124 of 202 unilateral aphakic eyes (61%), and 20/65 (range, 20/32 to 20/230) in 186 of 364 unilateral pseudophakic eyes (51%). The 5-year cumulative incidence of glaucoma or glaucoma suspect was 46% (95% CI, 28%-59%) in participants with bilateral aphakia, 7% (95% CI, 1%-12%) in those with bilateral pseudophakia, 25% (95% CI, 15%-34%) in those with unilateral aphakia, and 17% (95% CI, 5%-28%) in those with unilateral pseudophakia. The most common additional eye surgery was clearing the visual axis, with a 5-year cumulative incidence of 13% (95% CI, 8%-17%) in participants with bilateral aphakia, 33% (95% CI, 26%-39%) in those with bilateral pseudophakia, 11% (95% CI, 6%-15%) in those with unilateral aphakia, and 34% (95% CI, 28%-39%) in those with unilateral pseudophakia. The median 5-year change in spherical equivalent refractive error was -8.38 D (IQR, -11.38 D to -2.75 D) among 89 bilateral aphakic eyes, -1.63 D (IQR, -3.13 D to -0.25 D) among 130 bilateral pseudophakic eyes, -10.75 D (IQR, -20.50 D to -4.50 D) among 43 unilateral aphakic eyes, and -1.94 D (IQR, -3.25 D to -0.69 D) among 112 unilateral pseudophakic eyes. CONCLUSIONS AND RELEVANCE: In this cohort study, development of glaucoma or glaucoma suspect was common in children 5 years after lensectomy. Myopic shift was modest during the 5 years after placement of an intraocular lens, which should be factored into implant power selection. These results support frequent monitoring after pediatric cataract surgery to detect glaucoma, visual axis obscuration causing reduced vision, and refractive error.

In this report, we discovered a new entity named cataract, alopecia, oral mucosal disorder, and psoriasis-like (CAOP) syndrome in two unrelated and ethnically diverse patients. Furthermore, patient 1 failed to respond to regular treatment. We found that CAOP syndrome was caused by an autosomal recessive defect in the mitochondrial membrane-bound transcription factor peptidase/site-1 protease (MBTPS1, S1P). Mitochondrial abnormalities were observed in patient 1 with CAOP syndrome. Furthermore, we found that S1P is a novel mitochondrial protein that forms a trimeric complex with ETFA/ETFB. S1P enhances ETFA/ETFB flavination and maintains its stability. Patient S1P variants destabilize ETFA/ETFB, impair mitochondrial respiration, decrease fatty acid ß-oxidation activity, and shift mitochondrial oxidative phosphorylation (OXPHOS) to glycolysis. Mitochondrial dysfunction and inflammatory lesions in patient 1 were significantly ameliorated by riboflavin supplementation, which restored the stability of ETFA/ETFB. Our study discovered that mutations in MBTPS1 resulted in a new entity of CAOP syndrome and elucidated the mechanism of the mutations in the new disease.

Importance: Eye health in the homeless population is important, yet follow-up to referral appointments in this population remains low. Objective: To investigate the association of health coaching and transportation vouchers with follow-up rates at a free ophthalmology homeless shelter clinic. Design, Setting, and Participants: A prospective cohort study was conducted from January 9, 2019, to March 4, 2020, among all 71 patients evaluated at a free ophthalmology clinic at a single homeless shelter in San Francisco, California. Exposures: If indicated, patients were referred for advanced ophthalmologic care at a county hospital and free eyeglasses from a nonprofit organization. Main Outcomes and Measures: The primary outcome was follow-up rates to referral appointments. The secondary outcomes were prespecified baseline variables hypothesized to be associated with follow-up. The intervention began September 4, 2019. Follow-up rates were compared between the preintervention (n = 37) and postintervention (n = 34) groups. The hypothesis was formulated before data collection. Results: Among the 71 patients, 50 (70.4%) were men, and the mean (SD) age was 51.9 (12.4) years. A total of 28 patients (39.4%) were referred for free eyeglasses, 14 (19.7%) to the county hospital for advanced care, and 7 (9.9%) to both. Of those referred, the difference in follow-up from the postintervention to preintervention groups was 53.8% (95% CI, 39.8%-67.9%; P < .001). Compared with patients who did not follow up, those who did had a mean difference of 59 more days at the shelter (95% CI, 39-80 days; P = .003). Among patients with a visual acuity of 20/40 or worse in the better-seeing eye, the mean difference between those who did not follow up and those who did was 61% (95% CI, 44%-78%; P = .003). The mean difference in follow-up between patients who were born in the US and patients not born in the US was 89% (95% CI, 79%-98%; P = .02). Of those in the postintervention group, the difference in presentation to follow-up for patients with a high school diploma compared with those without was 59% (95% CI, 37%-81%; P = .001). Conclusions and Relevance: This study suggests that a health coaching and bus token intervention improved follow-up rates at a free ophthalmology homeless shelter clinic by at least 39.8%; this improvement supports considering implementation of this intervention when developing public assistance programs if independent corroboration is provided. Barriers to follow-up included a shorter duration of stay at the homeless shelter, visual acuity better than 20/40, not being born in the US, and lower educational level, although the size of this study does not permit determining if some or all of these are associated with one another.
