Sexual and reproductive health outcomes for forcibly displaced persons living in urban environments in low- and middle-income countries: a scoping review protocol.

OBJECTIVE: The objective of this review is to characterize the state of literature regarding forcibly displaced persons' sexual and reproductive health in urban areas in low- and middle-income countries. Specific objectives include describing the sexual and reproductive health outcomes among forcibly displaced persons relocating in urban environments. INTRODUCTION: As a result of persecution, conflict, violence, human rights violations, and disruptive events, 89.3 million people worldwide were forcibly displaced as of the end of 2021. Forcibly displaced people face a wide range of sexual and reproductive health challenges in their countries of origin, en route to final destinations, and on arrival in host communities. There is a growing urbanization of forcibly displaced persons, yet there is limited attention on sexual and reproductive health outcomes of this population. INCLUSION CRITERIA: This review will consider studies that include sexual and/or reproductive health outcomes and needs of forcibly displaced persons within urban environments in low- and middle-income countries. Published and unpublished evidence, including quantitative, qualitative, mixed methods research, and gray literature, will be eligible for inclusion. METHODS: MEDLINE, Embase, PsycINFO, CINAHL, IBSS, ASSIA, SSCI, and Global Medicus Index will be searched for English-language articles. Titles and abstracts will be screened against the inclusion criteria, followed by full-text review of potentially eligible studies, which will be independently assessed by 2 reviewers. Eligible articles will be extracted and charted. Results from extracted data will be tabulated and accompanied by a narrative summary to summarize and contextualize the extracted data to describe how the results relate to the review's objectives and question.

Relationship between peripheral refraction, axial lengths and parental myopia of young adult myopes.

PURPOSE: To determine the relationship between peripheral refraction at the horizontal retina, axial length and parental history of myopia between myopic adults who have positive parental myopia and those with negative parental myopia. METHODS: 69 males and 44 females in the age range of 18-25 years were assigned either a negative parental myopia (NPM) or positive parental myopia (PPM) group. In the corrected and uncorrected states, peripheral refractive error was measured up to 30° horizontally in 10° steps using an open field autorefractor. Axial length was measured using an Opto US1000 Fine A-Scan Ultrasonography (model US1000). RESULTS: Relative peripheral refractive error showed more hyperopic defocus that was statistically significantly more increased in the positive parental myopia group than in the negative parental myopia group (P ≥ 0.02). The overall mean ± SD axial length of all subjects was 23.38 ± 0.32 mm (range 23.01-25.01 mm). The study showed a statistically significant difference (P = 0.005) in axial lengths of young adult myopes (23.45 ± 0.36 mm) with parental myopia compared to those with similar spherical equivalent refraction who have non-myopic parents (23.28 ± 0.19 mm). CONCLUSION: There was significantly more hyperopic defocus at 30° N and 30° T retina in the corrected states of young adult myopes who had myopic parents compared to their counterparts with non-myopic parents.

Contact lens complications among wearers in Ghana.

PURPOSE: Contact lens (CL) practice is relatively new in Ghana; a country where the geographical location (warm climate) lends itself to harsh environmental conditions (high humidity) known to influence CL wear. Recent studies suggest an increase in CL wear (corrective and cosmetic), yet, there are no studies about CL-related complications. This study sought to determine the complications associated with CL wear in Ghana. METHODS: This was a retrospective cohort study. The medical records of contact lens wearers from five CL clinics in the two largest metropolises in Ghana, Accra and Kumasi, were reviewed. Included in the study were records of individuals who visited the clinics within the period of 2013-2016. Data on patients with contact lens-related complications were analyzed. RESULTS: The prevalence of CL complications was 29.06 %. The mean ±â€¯SD age of patients with CL complications was 35 ±â€¯15 years. Contact lens complications were more common in females (52.90 %). The majority of complications were in soft contact lens wearers (82.35 %). Refractive error correction was the most common indication for CL wear (61.76 %) among those with complications, followed by keratoconus (14.71 %), scarred blind eye (14.71 %), corneal ulcer (5.88 %) and anterior staphyloma (2.94 %). Contact lens complications reported were giant papillary conjunctivitis (41.18 %), corneal infiltrates (23.53 %), bacterial keratitis (14.71 %), corneal abrasion (11.76 %), dry eye (5.88 %) and corneal oedema (2.94 %). The causes of CL complication were inappropriate lens cleaning (29.41 %), poor hygiene (23.53 %), overnight contact lens wear (17.64 %), poor lens fit (14.71 %) and reaction to contact lens solution (14.71 %). CONCLUSION: Contact lens complications were more common in soft contact lens wearers in Ghana. Giant papillary conjunctivitis was the most common contact lens complication reported. Adherence to CL wear care regimen and good personal hygiene may prevent the majority of CL complications observed in Ghana.

Assessment of Ocular Surface Disease in Glaucoma Patients in Ghana.

PRECIS: Dry eye disease (DED) observed in this study is associated with ocular surface abnormalities as shown by specific dry eye tests. Changes in tear quality may be responsible for dry eye symptoms among the participants. PURPOSE: This study sought to evaluate DED in glaucoma patients in Ghana. MATERIALS AND METHODS: This was a hospital-based descriptive cross-sectional study involving glaucoma patients on topical glaucoma treatment for at least 6 months. The medical records of participants were thoroughly reviewed for information on demographics, ocular history, medical history, number of topical antiglaucoma medications used within the last 6 months, and any other ophthalmic medications used by the participants. An Ocular Surface Disease Index (OSDI) questionnaire was administered to each participant, after which Schirmer test and tear break-up time (TBUT) were performed on each participant in a controlled environment. RESULTS: A total of 100 individuals participated in the study. The mean±SD age of participants was 60.44±14.05 years. The majority (60.0%) of the participants were females and 55.0% of participants used 2 or more topical antiglaucoma medication. Of the participants, 81.0% reported subjective dry eye symptoms. Schirmer test and TBUT showed that 55.0% and 87.0% of the participants had decreased tear production and abnormal tear quality, respectively. Multiple logistic regression showed a significant association between age and abnormal OSDI (P=0.037), Schirmer test (P=0.003), and TBUT (P=0.042); the number of topical glaucoma medications and OSDI (P=0.016) and Schirmer test (P=0.009). The prevalence of DED was 23.0%. Increasing age was associated with an ∼7 times higher odds of having DED (P=0.0019), using >2 glaucoma medications with ∼4.5 times higher odds of having DED (P=0.001), 5 or more years of glaucoma medication use with ∼4 times higher odds of DED (P=0.009), and both benzalkonium chloride and sodium chlorite as preservative was associated with ∼3.5 times higher odds of DED (P=0.047). CONCLUSION: DED is prevalent among glaucoma patients in Ghana and is associated with age, duration of glaucoma medication, type of preservatives, and number of topical glaucoma medications.

Career aspirations and factors influencing career choices of optometry students in Ghana.

Optometry students in clinical years are usually faced with the challenges of making a career choice in or outside optometry. This cross sectional study was conducted to investigate the career aspirations of optometry students in Ghana. All students in their fourth to sixth year who consented to participate in the study responded to a questionnaire which explored: demographic characteristics, career aspirations, and factors influencing their choices. Descriptive statistics was used to present data as frequencies, proportions and percentages. Chi-square test and logistic regression analysis were used to evaluate relationships between variables. Two hundred and nine students from the two optometry training institutions in Ghana; Kwame Nkrumah University of Science and Technology (49.8%) and University of Cape Coast (51.2%) responded to the questionnaire. The mean (SD) age of students was 23.6 (1.9) years (males = 65.6%). On seeking admission into the university, optometry (65.6%) and human biology/medicine (28.2%) were the leading first choice programmes among participants. Participants largely aspire to be in clinical practice (64.6%) or Academia/Research (28.2%). The major factors which influenced career choices were interest in career field (64.1%) and potential good income (38.3%). Females were twice more likely to practice optometry and pursue an interest in paediatric optometry than males. Institution of study (p = .028) and information on career opportunities (p = .018) were significant predictors of students' decision to pursue a career in academia/research. Optometry students in Ghana largely aspire to be in clinical practice, a finding which is useful for optometry training institutions and relevant stakeholders in developing the optometry programme and projecting its future in Ghana.

Comparison of the clinical estimation of cup-to-disk ratio by direct ophthalmoscopy and optical coherence tomography.

OBJECTIVE: To compare the clinical estimation of cup-to-disk ratio determined by direct ophthalmoscopy and optical coherence tomography in glaucoma diagnosis and monitoring. METHODS: A retrospective, cross-sectional study involving a review of 71 optical coherence tomography scans dating from June 2011 to January 2012 at a private imaging lab in Ghana. At the respective referring facilities, only 31 out of the 71 corresponding patient records were successfully reviewed. RESULTS: Majority (54.84%) of the 31 patient records successfully reviewed were women. The mean age was 44.54 ± 16.15 years. Cup-to-disk ratio was grouped into ⩽0.4, >0.4-0.6, >0.6-0.8, and >0.8-1.0 based on direct ophthalmoscopy values. The overall mean cup-to-disk ratio estimated by the optical coherence tomography and direct ophthalmoscopy were 0.72 ± 0.21 and 0.60 ± 0.26, respectively. Overall, there was no statistically significant difference in the mean cup-to-disk ratio estimation by direct ophthalmoscopy and optical coherence tomography [right eye (p = 0.0629); left eye (p = 0.0766)]. There was a statistically significant difference between direct ophthalmoscopy and optical coherence tomography cup-to-disk ratio estimation for values ⩽0.4 [right eye (p = 0.0061); left eye (p = 0.0063)] and values >0.4-0.6 [right eye (p = 0.0243); left eye (p = 0.0498)]. There was no statistically significant difference between conventional direct ophthalmoscopy and optical coherence tomography cup-to-disk ratio estimation for cup-to-disk ratio >0.6. CONCLUSION: We recommend clinicians document which method they use in evaluating optic nerve head parameters. This is to ensure that subsequent clinical decisions are not influenced by an apparent change in these parameters, especially cup-to-disk ratio as different methods might give different values.

Relationship between Reduced Accommodative Lag and Myopia Progression.

PURPOSE: To determine the relationship between accommodative lag and rate of myopia progression when Ghanaian myopic school children are either undercorrected or fully corrected with single vision lenses. METHODS: A 2-year single masked randomized control trial was conducted using 150 Ghanaian myopic children aged 10 to 15 years with mean baseline myopia of -1.98 ± 0.50D. The children were randomly assigned to wear either a full correction (n = 75) or +0.50D undercorrection (UC) (n = 75) single vision lenses. Repeated measurements which included refractive error and accommodative response at 33 and 28.6 cm for FC and UC, respectively, were performed using Open-Field Autorefractor whereas ocular biometry results were obtained using A-Scan ultrasonography. Results were based on the right eye and analyzed using STATA 11. RESULTS: After 24 months, the mean myopia progression of children in the FC group (-0.54 ± 0.26D) was not significantly different from that of the children in the UC group (-0.5 ± 0.22D) (p = 0.31). There was no significant difference between the mean values of the initial near lag and the average lag measured 24 months later in both groups (FC: initial lag -0.74 ± 0.17D, average lag -0.72 ± 0.15D, p = 0.44; UC: initial lag -0.57 ± 0.14D, average lag -0.58 ± 0.15D; p = 0.67). Also, there was no significant correlation between refractive change seen in 24 months and either the first near lag for both FC (r = -0.05, p = 0.43) and UC (r = -0.08, p = 0.43) or the average near lag of accommodation for both FC (r = -0.02, p = 0.49) and UC (r = -0.04, p = 0.49). CONCLUSIONS: This study showed no relationship between lag of accommodation and rate of myopia progression in children with progressing myopia. Different ethnic groups may respond differently to the same size of hyperopic blur.

Assessment of corneal astigmatism following frown and straight incision forms in sutureless manual small incision cataract surgery.

To investigate which of two tunnel incision forms (frown versus straight) in sutureless manual small incision cataract surgery creates more corneal astigmatism. Sixty eyes of 60 patients who had consented to undergo cataract surgery and to partake in this study were followed from baseline through >12-week postoperative period. Values of preoperative and postoperative corneal astigmatism for the 60 eyes, measured with a Bausch and Lomb keratometer, were extracted from the patients' cataract surgery records. Residual astigmatism was computed as the difference between preoperative and postoperative keratometry readings. Visual acuity was assessed during the preoperative period and at each postoperative visit with a Snellen chart at 6 m. Fifty eyes of 50 patients were successfully followed-up on. Overall, the mean residual astigmatism was 0.75±0.12 diopters. The differences in mean residual astigmatism between the two different incision groups were statistically significant (t [48]=6.33, P<0.05); frown incision group recorded 1.00±0.12 diopters, whereas the straight incision group recorded 0.50±0.12 diopters. No significant difference was observed between male and female groups (t [48]=0.24, P>0.05). Residual corneal astigmatism in the frown incision group was significantly higher than in the straight incision group. Fisher's exact test did not reveal a significant association between incision forms and visual acuity during the entire postoperative period (P>0.05).

Refractive error and visual impairment in private school children in Ghana.

PURPOSE: To assess the prevalence of refractive error and visual impairment in private school children in Ghana. METHODS: A random selection of geographically defined classes in clusters was used to identify a sample of school children aged 12 to 15 years in the Ashanti Region. Children in 60 clusters were enumerated and examined in classrooms. The examination included visual acuity, retinoscopy, autorefraction under cycloplegia, and examination of anterior segment, media, and fundus. For quality assurance, a random sample of children with reduced and normal vision were selected and re-examined independently. RESULTS: A total of 2454 children attending 53 private schools were enumerated, and of these, 2435 (99.2%) were examined. Prevalence of uncorrected, presenting, and best visual acuity of 20/40 or worse in the better eye was 3.7, 3.5, and 0.4%, respectively. Refractive error was the cause of reduced vision in 71.7% of 152 eyes, amblyopia in 9.9%, retinal disorders in 5.9%, and corneal opacity in 4.6%. Exterior and anterior segment abnormalities occurred in 43 (1.8%) children. Myopia (at least -0.50 D) in one or both eyes was present in 3.2% of children when measured with retinoscopy and in 3.4% measured with autorefraction. Myopia was not significantly associated with gender (P = 0.82). Hyperopia (+2.00 D or more) in at least one eye was present in 0.3% of children with retinoscopy and autorefraction. CONCLUSIONS: The prevalence of reduced vision in Ghanaian private school children due to uncorrected refractive error was low. However, the prevalence of amblyopia, retinal disorders, and corneal opacities indicate the need for early interventions.
