Implementation of a pediatric trauma registry at a national referral center in Kenya: Utility and concern for sustainability.

BACKGROUND: Pediatric trauma disproportionately affects low- and middle-income countries, particularly the pediatric trauma systems, are frequently limited. This study assessed the patterns of pediatric traumatic injuries and treatment at the only free-standing public children's hospital in East Africa as well as the implementation and sustainability of the trauma registry. METHODS: A prospective pediatric trauma registry was established at Shoe4Africa Children's Hospital (S4A) in Eldoret, Kenya. All trauma patients over a six-month period were enrolled. Descriptive analyses were completed via SAS 9.4 to uncover patterns of demographics, trauma mechanisms and injuries, as well as outcomes. Implementation was assessed using the RE-AIM framework. RESULTS: The 425 patients had a median age of 5.14 years (IQR 2.4, 8.7). Average time to care was 267.5 min (IQR 134.0, 625.0). The most common pediatric trauma mechanisms were falls (32.7 %) and burns (17.7 %), but when stratified by age group, toddlers had a higher risk of sustaining injuries from burns and poisonings. Over half (56.2 %) required an operation during the hospitalization. Overall, implementation of the registry was limited by the clinical burden and inadequate personnel. Sustainability of the registry was limited by finances. CONCLUSIONS: This is the first study to describe the trauma epidemiology from a Kenyan public pediatric hospital. Maintenance of the trauma registry failed due to cost. Streamlining global surgery efforts through implementation science may allow easier development of trauma registries to then identify modifiable risk factors to prevent trauma and long-term outcomes to understand associated disability.

Demographics and medical school exposures to rural health influence future practice.

BACKGROUND: One-fifth of the US population lives in rural areas. A record number of rural hospitals have closed, creating increased burdens on regional centers and delays in care. This study aimed to assess medical student perceptions of rural surgery and health care, and to elucidate influential factors for future practice. METHODS: We administered a survey to medical schools throughout Indiana, Illinois, and Michigan. The survey was designed and evaluated by a survey content expert and piloted among a group of students. Student and faculty liaisons disseminated the survey between February and May 2021. Descriptive analysis of data was completed using Stata v.16.1 (StataCorp, LLC, College Station, TX). RESULTS: The respondents included 700 medical students; 59.5% were female, with an equal distribution across medical school classes. More than 98% of students believe we "lack" or "are in great need of" rural health care providers, as well as rural surgeons; however, more than half of the students did not agree that the rural workforce is declining. Only 15.7% of students reported an interest in "pursuing a future career in a rural setting." Students with exposure to rural health care, coming from a rural hometown, or having a dependent had a positive association with interest in pursuing rural practice. CONCLUSION: Although students are aware of the lack of rural surgeons and health care providers, there remains an educational deficit. Expanding exposure to rural health care and surgery while in medical school may increase the number of students interested in pursuing a career in a rural setting, potentially shrinking the rural workforce gap.

Uncovering the Overlap of Global and Domestic Rural Surgery for Medical Trainees.

INTRODUCTION: Medical trainees who participate in global rotations demonstrate improved cultural sensitivity, increased involvement in humanitarian efforts, and ability to adapt to limited resources. The global coronavirus pandemic halted global rotations for medical trainees. Domestic rural surgery (DRS) may offer a unique alternative. We aimed to understand medical students' perceptions of the similarities and differences between global surgery and DRS and how students' priorities impact career choices. METHODS: An electronic survey was administered at eleven medical training institutions in Indiana, Illinois, and Michigan in spring 2021. Mixed methods analysis was performed for students who reported an interest in global surgery. Quantitative analysis was completed using Stata 16.1. RESULTS: Of the 697 medical student respondents, 202 were interested in global surgery. Of those, only 18.3% were also interested in DRS. Students interested in DRS had more rural exposures. Rural exposures associated with DRS interest were pre-clinical courses (P = 0.002), clinical rotations (P = 0.045), and rural health interest groups (P < 0.001). Students interested in DRS and those unsure were less likely to prioritize careers involving teaching or research, program prestige, perceived career advancement, and well-equipped facilities. The students who were unsure were willing to utilize DRS exposures. CONCLUSIONS: Students interested in global surgery express a desire to practice in low-resource settings. Increased DRS exposures may help students to understand the overlap between global surgery and DRS when it comes to working with limited resources, achieving work-life balance and practice location.

Uncomplicated gastroschisis care in the US and Kenya: Treatment at two tertiary care centers.

BACKGROUND: Gastroschisis is a common birth defect with < 5% mortality in high income countries, but mortality in sub Saharan Africa remains high. We sought to compare gastroschisis management strategies and patient outcomes at tertiary pediatric referral centers in the United States and Kenya. METHODS: This retrospective chart review examined uncomplicated gastroschisis patients treated at Riley Hospital for Children in Indianapolis, USA (n = 110), and Shoe4Africa Children's Hospital in Eldoret, Kenya (n = 75), from 2010 to 2018. Analyzed were completed using Chi square, Fisher's exact, and independent samples t tests and medians tests at the 95% significance level. RESULTS: Survival in the American cohort was double that of the Kenyan cohort (99.1% vs 45.3%, p< 0.001). Sterile bag use for bowel containment was lower in Kenya (81.3% vs 98.1%, p< 0.001), but silo use was comparable at both institutions (p = 0.811). Kenyan patients had earlier median enteral feeding initiation (4vs 10 days, p< 0.001) and accelerated achievement of full enteral feeding (10vs 23 days, p< 0.001), but none received TPN. Despite earlier feeding, Kenyan patients displayed a higher prevalence of wound infections (70.8% vs 17.1%, p< 0.001) and sepsis (43.9% vs 4.8%, p< 0.001). In Kenya, survivors and non survivors displayed no difference in sterile bag use, hemodynamic stability, all cause infection rates, or antibiotic free hospital days. Defect closure (p< 0.001) and enteral feeding initiation (p< 0.001) were most predictive of survival. CONCLUSION: Improving immediate response strategies for gastroschisis in Kenya could improve survival and decrease infection rates. Care strategies in the US can center on earlier enteral feeding initiation to reduce time to full feeding. LEVEL OF EVIDENCE: Level III.

The role of community health workers in the surgical cascade: a scoping review.

BACKGROUND: Community health workers (CHWs) can increase access to various primary healthcare services; however, their potential for improving surgical care is under-explored. We sought to assess the role of CHWs in the surgical cascade, defined as disease screening, linkage to operative care, and post-operative care. Given the well-described literature on CHWs and screening, we focused on the latter two steps of the surgical cascade. METHODS: We conducted a scoping review of the peer-reviewed literature. We searched for studies published in any language from January 1, 2000 to May 1, 2020 using electronic literature databases including Pubmed/MEDLINE, Web of Science, SCOPUS, and Google Scholar. We included articles on CHW involvement in linkage to operative care and/or post-operative surgical care. Narrative and descriptive methods were used to analyze the data. RESULTS: The initial search identified 145 articles relevant to steps in the surgical cascade. Ten studies met our inclusion criteria and were included for review. In linkage to care, CHWs helped increase surgical enrollment, provide resources for vulnerable patients, and build trust in healthcare services. Post-operatively, CHWs acted as effective monitors for surgical-site infections and provided socially isolated patients with support and linkage to additional services. The complex and wide-ranging needs of surgical patients illustrated the need to view surgical care as a continuum rather than a singular operative event. CONCLUSION: While the current literature is limited, CHWs were able to maneuver complex medical, cultural, and social barriers to surgical care by linking patients to counseling, education, and community resources, as well as post-operative infection prevention services. Future studies would benefit from more rigorous study designs and larger sample sizes to further elucidate the role CHWs can serve in the surgical cascade.

Gender Differences in Insurance, Surgical Admissions and Outcomes at a Kenyan Referral Hospital.

INTRODUCTION: Gender is an important factor in determining access to healthcare resources. Women face additional barriers, especially in low- and middle-income countries. Surgical costs can be devastating, which can exacerbate engendered disparities. Kenya's National Hospital Insurance Fund (NHIF) aims to achieve universal coverage and protect beneficiaries from catastrophic health expenditures. We examine gender differences in NHIF coverage, health-seeking behavior, and surgical outcomes at a tertiary care hospital in Eldoret, Kenya. MATERIALS AND METHODS: All patients ≥13 years admitted to the general surgery service at Moi Teaching and Referral Hospital from January 2018-July 2018 were enrolled. Health records were retrospectively reviewed for demographic data, clinical parameters, NHIF enrollment, and cost information. Descriptive analyses utilized Wilcoxon Rank Sum, Pearson's Chi-square, and Fisher's Exact tests. RESULTS: 366 patients were included for analysis. 48.6% were enrolled in NHIF with significant female predominance (64.8% versus 37.9%, P < 0.0001). Despite differing coverage rates, male and female patients underwent surgery and suffered in-hospital mortality at similar rates. However, women only comprised 39.6% of admissions and were significantly more likely to delay care (median 60 versus 7 days, P < 0.0001), be diagnosed with cancer (26.6% versus 13.2%, P = 0.0024), and require a palliative procedure for cancer (44.1% versus 13.0%, P = 0.013). CONCLUSION: Many financial and cultural barriers exist in Kenya that prevent women from accessing healthcare as readily as men, persisting despite higher rates of NHIF coverage amongst female patients. Investigation into extra-hospital costs and social disempowerment for women may elucidate key needs for achieving health equity.

Use of a Novel Trigger Tool to Identify Palliative Care Needs in Surgical Patients at a National Referral Hospital in Kenya: A Pilot Study.

Background: Addressing unmet palliative care needs in high-risk surgical patients in low- and middle-income countries must include innovative approaches to limitations in personnel and culturally acceptable assessment modalities. Objectives: We assessed the utility of a novel seven-item "Step-1" trigger tool in identifying surgical patients who may benefit from palliative care. Design: All adult patients (≥18 years) on general surgery, neurosurgery, and orthopedic surgery wards were enrolled over a four-month period. Setting/Subjects: This study took place at Moi Teaching and Referral Hospital (MTRH), one of two Kenyan national referral hospitals. Measurements: The "Step-1" trigger tool was administered, capturing provider estimates of prognosis, cancer history, social barriers, admission frequency, hospice history, symptom burden, and functional decline/wasting. A cut-point of ≥3 positive factors was selected, indicating a patient may benefit from palliative care. Results: A total of 411 patients were included for analysis. Twenty-five percent (n = 102) of patients had scores ≥3. The cut-point of ≥3 was significantly associated with identifying high-risk patients (HRP; χ2 = 32.3, p < 0.01), defined as those who died or were palliatively discharged, with a sensitivity and specificity of 63.9% and 78.9%, respectively. Survey questions with the highest overall impact included: "Would you be not surprised if the patient died within 12 months?," "Are there uncontrolled symptoms?," and "Is there functional decline/wasting?" Conclusions: This pilot study demonstrates that the "Step-One" trigger tool is a simple and effective method to identify HRP in resource-limited settings. Although this study identified three highly effective questions, the seven-question assessment is flexible and can be adapted to different settings.

Arteritic Orbital Ischemia Producing Afferent and Efferent Pupillary Defects.

A 67-year-old woman presented with acute loss of vision to no light perception (NLP), a right afferent pupillary defect, and anisocoria with a nonreactive and dilated pupil in the right eye. Fundus examination showed pallid optic disc edema and a central retinal artery occlusion (CRAO) in the right eye. A temporal artery biopsy showed giant cell arteritis (GCA). Orbital involvement in GCA has been reported previously. However the combination of an afferent and efferent pupillary defect, NLP vision, pallid disc edema, and a CRAO in an elderly patient is likely a unique clinical combination that should strongly suggest GCA. Clinicians should be aware of the myriad presentations of GCA, including orbital ischemia.

"Testing is Healthy" TimePlay campaign: Evaluation of sexual health promotion gamification intervention targeting young adults.

OBJECTIVES: The objectives of the study were to 1) describe the implementation of the "Testing is Healthy" campaign in four locations in British Columbia (BC) and 2) report process evaluation indicators for the campaign. PARTICIPANTS: Young adults ages 20-29 years, the age group with the highest reported rates of chlamydia and gonorrhea in BC. SETTINGS: Movie theatres located in Langley, Burnaby, Coquitlam and Surrey, which are communities served by the Fraser Health Authority (FHA) in BC. INTERVENTION: The FHA launched the campaign in 2014 and 2015 to bring down the prevalence of sexually transmitted infections (STIs) and HIV in the region. The campaign used the Cineplex TimePlay platform to engage moviegoers in answering STI/HIV-related questions, and to connect them to a clinic finder on the BC Centre for Disease Control Sex Smart Resource (SSR) website. TimePlay includes elements of gaming, is technology-based, and has been a successful advertisement platform for consumer products and services. However, this is the first time it has been used for sexual health promotion. The campaign was evaluated for 1) reach, based on theatre attendance and TimePlay participation, and 2) the effectiveness of connecting people to sexual health information using SSR web analytics. OUTCOMES: In total, the campaign received 548 410 views and 77 149 plays. SSR web analytics showed a significant increase in unique page views of the Clinic Finder page between the first and the second campaign. IMPLICATIONS: The campaign reached a large population at a low cost and was correlated with spikes in the unique page views for the Clinic Finder page.

Necrotizing Fasciitis of the Periorbital Region Complicated by Combined Central Retinal Artery Occlusion, Central Retinal Vein Occlusion, and Posterior Ciliary Occlusion.

A 50 year-old man on immunosuppressive agents presented with left eye vision loss, periorbital swelling, pain, and ophthalmoplegia. The patient was clinically found to have a central retinal artery and vein occlusion. A CT scan was performed which demonstrated intraorbital fat stranding, however the patient lacked sinus disease. The etiology of the orbital infection was held in question. The area was debrided in the operating room, and the specimen demonstrated group A streptococcal species consistent with necrotizing fasciitis. Periorbital necrotizing fasciitis should be suspected in patients with rapidly progressive orbital symptoms without sinus disease as lack of surgical intervention can result in poor outcomes. The unusual aspect to this case is the mechanism of vision loss, as the authors hypothesize that there was vascular infiltration of the infection resulting in the central retinal artery occlusion and central retinal vein occlusion which have not been previously reported secondary to necrotizing fasciitis of the orbit.

Modulation of postprandial lipaemia by a single meal containing a commonly consumed interesterified palmitic acid-rich fat blend compared to a non-interesterified equivalent.

PURPOSE: Interesterification of palm stearin and palm kernal (PSt/PK) is widely used by the food industry to create fats with desirable functional characteristics for applications in spreads and bakery products, negating the need for trans fatty acids. Previous studies have reported reduced postprandial lipaemia, an independent risk factor for CVD, following interesterified (IE) palmitic and stearic acid-rich fats that are not currently widely used by the food industry. The current study investigates the effect of the most commonly consumed PSt/PK IE blend on postprandial lipaemia. METHODS: A randomised, controlled, crossover (1 week washout) double-blind design study (n = 12 healthy males, 18-45 years), compared the postprandial (0-4 h) effects of meals containing 50 g fat [PSt/PK (80:20); IE vs. non-IE] on changes in plasma triacylglycerol (TAG), glucose, glucose-dependent insulinotropic polypeptide (GIP), peptide YY (PYY), insulin, gastric emptying (paracetamol concentrations) and satiety (visual analogue scales). RESULTS: The postprandial increase in plasma TAG was higher following the IE PSt/PK versus the non-IE PSt/PK, with a 51 % greater incremental area under the curve [mean difference with 95 % CI 41 (23, 58) mmol/L min P = 0.001]. The pattern of lipaemia was different between meals; at 4-h plasma TAG concentrations declined following the IE fat but continued to rise following the non-IE fat. Insulin, glucose, paracetamol, PYY and GIP concentrations increased significantly after the test meals (time effect; P < 0.001 for all), but did not differ between test meals. Feelings of fullness were higher following the non-IE PSt/PK meal (diet effect; P = 0.034). No other significant differences were noted. CONCLUSIONS: Interesterification of PSt/PK increases early phase postprandial lipaemia (0-4 h); however, further investigation during the late postprandial phase (4-8 h) is warranted to determine the rate of return to baseline values. TRIAL REGISTRATION NUMBER: Clinicaltrials.gov as NCT02365987.

The rhesus rhadinovirus CD200 homologue affects immune responses and viral loads during in vivo infection.

UNLABELLED: Rhesus macaque rhadinovirus (RRV) is a gammaherpesvirus of rhesus macaque (RM) monkeys that is closely related to human herpesvirus 8 (HHV-8)/Kaposi's Sarcoma-associated herpesvirus (KSHV), and it is capable of inducing diseases in simian immunodeficiency virus (SIV)-infected RM that are similar to those seen in humans coinfected with HIV and HHV-8. Both HHV-8 and RRV encode viral CD200 (vCD200) molecules that are homologues of cellular CD200, a membrane glycoprotein that regulates immune responses and helps maintain immune homeostasis via interactions with the CD200 receptor (CD200R). Though the functions of RRV and HHV-8 vCD200 molecules have been examined in vitro, the precise roles that these viral proteins play during in vivo infection remain unknown. Thus, to address the contributions of RRV vCD200 to immune regulation and disease in vivo, we generated a form of RRV that lacked expression of vCD200 for use in infection studies in RM. Our data indicated that RRV vCD200 expression limits immune responses against RRV at early times postinfection and also impacts viral loads, but it does not appear to have significant effects on disease development. Further, examination of the distribution pattern of CD200R in RM indicated that this receptor is expressed on a majority of cells in peripheral blood mononuclear cells, including B and T cells, suggesting potentially wider regulatory capabilities for both vCD200 and CD200 that are not strictly limited to myeloid lineage cells. In addition, we also demonstrate that RRV infection affects CD200R expression levels in vivo, although vCD200 expression does not play a role in this phenomenon. IMPORTANCE: Cellular CD200 and its receptor, CD200R, compose a pathway that is important in regulating immune responses and is known to play a role in a variety of human diseases. A number of pathogens have been found to modulate the CD200-CD200R pathway during infection, including human herpesvirus 8 (HHV-8), the causative agent of Kaposi's sarcoma and B cell neoplasms in AIDS patients, and a closely related primate virus, rhesus macaque rhadinovirus (RRV), which infects and induces disease in rhesus macaque monkeys. HHV-8 and RRV encode homologues of CD200, termed vCD200, which are thought to play a role in preventing immune responses against these viruses. However, neither molecule has been studied in an in vivo model of infection to address their actual contributions to immunoregulation and disease. Here we report findings from our studies in which we analyzed the properties of a mutant form of RRV that lacks vCD200 expression in infected rhesus macaques.

Neovascular glaucoma in a child: an unusual presentation of medulloepithelioma.

A healthy 12 month old infant without significant medical history presented with left eye redness for one week. Ophthalmic examination showed elevated intraocular pressure with iris neovascularization in the affected eye with increased optic nerve cupping. Scleral depression revealed a ciliary body mass in the supratemporal quadrant. A large, non-pigmented, vascular mass was noted; biopsy results showed multilayered cords, tubules, and sheets resembling primitive medullary epithelium arising from the ciliary body. The patient was diagnosed with medulloepithelioma. The patient underwent enucleation of the affected eye. Medulloepithelioma is a rare but important cause of neovascular glaucoma in the pediatric population. This case will focus on the characteristics of medulloepthelioma and the differential diagnosis for a non-pigmented ciliary body mass in a child.

Comparison of multiple stereoscopic and monoscopic digital image formats to film for diabetic macular edema evaluation.

PURPOSE: To assess agreement between evaluations of monoscopic and stereoscopic digital images versus stereo film photographs in diabetic macular edema (DME). METHODS: A 152-eye group of digital monoscopic macular images (seven-field sets and wide-angle mosaics) were compared with digital stereoscopic images (uncompressed and compressed seven-field sets) and stereo 35-mm film photos (Early Treatment Diabetic Retinopathy Study protocol) for the presence of hard exudates (HE), retinal thickening (RT), clinically significant macular edema (CSME), and RT at the center of the macular (RTCM). RESULTS: Agreement, according to the κ statistic, was almost perfect in identifying HE and RT between all digital formats and stereo film (HE, κ = 0.81-0.87; RT, κ = 0.87-0.92). Distribution in all digital formats was not significantly different from that in film (Bhapkar test: HE, P = 0.20-0.40; RT, P = 0.06-1.0). CSME and RTCM grading differences were either significant or trended toward significance. The readers detected CSME and RTCM in film images more often than in digital formats. In identifying DME features, agreement between evaluations of monoscopic digital formats and film was similar to that between stereo digital formats and film, and the performance of uncompressed images versus film was similar to that of compressed images versus film. Repeatability between readers was similar in evaluations of film and all digital formats. Repeatability in identifying RTCM was lower than that of other DME components in film and all digital formats. CONCLUSIONS: Stereoscopic digital formats are equivalent to monoscopic for DME evaluation, but digital photography is not as sensitive as film in detecting CSME and RTCM.

Iridociliochoroidal melanoma arising from melanocytoma in a black teenager.

We report a ciliary body melanoma that apparently arose from a melanocytoma in a 15-year-old black teenager. The eye was enucleated, and metastatic evaluation remained negative at 5 years' follow-up. This unusual case, confirmed histopathologically, reveals that young patients with melanocytoma can have malignant transformation at an early age.

Giant choroidal nevus clinical features and natural course in 322 cases.

PURPOSE: Evaluation of clinical features and natural course of giant choroidal nevi (diameter >or=10 mm). DESIGN: Retrospective observational case series. PARTICIPANTS: We included 322 eyes of 322 patients. METHODS: Clinic-based study of tumor features, tumor outcome, and vision outcome. Kaplan-Meier analysis was used to assess time to transformation into melanoma. Cox proportional hazards regressions evaluated clinical factors predictive of nevus transformation into melanoma and nevus-related decreased vision (defined as <20/20 and unrelated to other eye pathology). MAIN OUTCOME MEASURES: Transformation of giant choroidal nevus into melanoma and nevus-related decreased vision. RESULTS: A medical record review of 4100 patients diagnosed with choroidal nevus identified 322 (8%) giant choroidal nevi. Median nevus basal diameter was 11 mm (range, 10-24). Median thickness was 1.9 mm (range, 0-4.4). Related retinal findings included drusen overlying nevus (n = 261 [81%]), subretinal fluid (n = 26 [8%]), orange pigment (n = 4 [1%]), retinal pigment epithelial (RPE) detachment (n = 6 [2%]), hyperplasia (n = 48 [15%]), fibrous metaplasia (n = 48 [15%]), atrophy (n = 63 [20%]), or trough (n = 6 [2%]). Kaplan-Meier analysis estimated transformation into melanoma in 13% at 5 years and 18% at 10 years. Multivariate analyses revealed factors predictive of transformation into melanoma including involvement or close proximity to the foveola (P = 0.017) and acoustic hollowness (P = 0.052). Nevus-related decreased vision was found in 2.2% of eyes at initial visit and 3.7% at final visit (median 41 and mean 61 months follow-up). Factors associated with nevus-related decreased vision at initial visit included subretinal fluid (P = 0.001), involvement or close proximity to foveola (P = 0.005), RPE detachment (P = 0.033), and nevus-related choroidal neovascular membrane (P = 0.044). Factors predictive of nevus-related decreased vision at final visit included involvement or close proximity to the foveola (P = 0.001) and presence of symptoms at the initial visit (P = 0.032). CONCLUSIONS: Giant choroidal nevi can clinically resemble choroidal melanoma but show features of chronicity, such as overlying drusen and RPE alterations. Over time, 18% transformed into melanoma, underscoring the importance of life-long surveillance.

Comparison of time-domain OCT and fundus photographic assessments of retinal thickening in eyes with diabetic macular edema.

PURPOSE: To explore the correlation between optical coherence tomography (OCT) and stereoscopic fundus photographs (FP) for the assessment of retinal thickening (RT) in diabetic macular edema (DME) within a clinical trial. METHODS: OCT, FP, and best corrected visual acuity (VA) measurements were obtained in both eyes of 263 participants in a trial comparing two photocoagulation techniques for DME. Correlation coefficients (r) were calculated comparing RT measured by OCT, RT estimated from FP, and VA. Principal variables were central subfield retinal thickness (CSRT) obtained from the OCT fast macular map and DME severity assessed by a reading center using a seven-step photographic scale combining the area of thickened retina within 1 disc diameter of the foveal center and thickening at the center. RESULTS: Medians (quartiles) for retinal thickness within the center subfield by OCT at baseline increased from 236 (214, 264) microm in the lowest level of the photographic scale to 517 (455, 598) microm in the highest level (r = 0.67). However, CSRT interquartile ranges were broad and overlapping between FP scale levels, and there were many outliers. Correlations between either modality and VA were weaker (r = 0.57 for CSRT, and r = 0.47 for the FP scale). OCT appeared to be more reproducible and more sensitive to change in RT between baseline and 1 year than was FP. CONCLUSIONS: There was a moderate correlation between OCT and FP assessments of RT in patients with DME and slightly less correlation of either measure with VA. OCT and FP provide complementary information but neither is a reliable surrogate for VA.
