Identifying the ophthalmic needs of families living in Toronto shelters

Evaluating the Efficacy of Teleophthalmology in Delivering Ophthalmic Care to Underserved Populations: A Literature Review

Technological advancement has brought commendable changes in medicine, advancing diagnosis, treatment, and interventions. Telemedicine has been adopted by various subspecialties including ophthalmology. Over the years, teleophthalmology has been implemented in various countries, and continuous progress is being made in this area. In underserved populations, due to socioeconomic factors, there is little or no access to healthcare facilities, and people are at higher risk of eye diseases and vision impairment. Transportation is the major hurdle for these people in obtaining access to eye care in the main hospitals. There is a dire need for accessible eye care for such populations, and teleophthalmology is the ray of hope for providing eye care facilities to underserved people. Numerous studies have reported the advantages of teleophthalmology for rural populations such as being cost-effective, timesaving, reliable, efficient, and satisfactory for patients. Although it is being practiced in urban populations, for rural populations, its benefits amplify. However, there are certain obstacles as well, such as the cost of equipment, lack of steady electricity and internet supply in rural areas, and the attitude of people in certain regions toward acceptance of teleophthalmology. In this review, we have discussed in detail eye health in rural populations, teleophthalmology, and its effectiveness in rural populations of different countries.

Visual and Ocular Conditions among a Homeless Adult Population of Boston

SIGNIFICANCE

The eye care needs of the homeless population in the United States are not well known. This study elucidates those needs for health care for the homeless programs and eye care practitioners. This information could result in an increase in the provision of necessary eye care services.

PURPOSE

The purpose of this study was to assess the extent of visual and ocular conditions, the frequency of eyeglass orders and receipt of eyeglasses, and the frequency of ophthalmology referrals and receipt of ophthalmological care in an adult homeless population in Boston.

METHODS

A cross-sectional retrospective chart review was conducted for patients of the Boston Health Care for the Homeless Program's Pine Street Inn eye clinic from September 26, 2016, to December 31, 2017. Data on sociodemographics, medical history, comprehensive eye examination findings, glasses orders and receipt, and ophthalmology referrals and receipt of care were collected and analyzed.

RESULTS

A total of 424 patients were included in the study. The mean age of the study population was 52.7 (interquartile range, 46 to 60), and the majority were male (74%). The most common systemic conditions were hypertension (40.6%) and diabetes (23.8%). The most common refractive error was presbyopia (67.7%), followed by astigmatism (38.9%), hyperopia (34.0%), and myopia (30.7%). The most common ocular conditions were dry eye (28.6%), visually or clinically significant cataract (20%), and glaucoma/glaucoma suspicion (13.9%). Refractive correction was indicated for 356 patients (84%), but 82 (29%) did not receive ordered eyeglasses. Ophthalmology referrals were placed for 61 patients (14.4%), yet only 20 (32.8%) of those referrals were completed.

CONCLUSIONS

A significant need for refractive correction and a large gap for ophthalmological care were found among the study population. Health care for the homeless programs and eye care practitioners should be aware of the visual and ocular needs of this patient population so as to better meet their needs.

Visual impairment and the prevalence of ocular pathology in homeless children and adults globally: a systematic review

BACKGROUND

Homelessness is a global issue in developing and developed countries. This article is the first systematic review to explore its impact on visual health globally.

METHODS

A systematic literature search was conducted on OVID MEDLINE, EMBASE, and Cochrane CENTRAL. Peer-reviewed English-language studies with a focus on homeless children or adults that reported on ocular outcomes were included. Primary outcomes and secondary endpoints were reported via weighted averages. Primary outcomes between homeless children and homeless adults were compared using the Fisher exact test.

RESULTS

There were 5774 individuals across 23 full-text articles included in the review. For studies reporting primary outcomes, 36.8% of homeless individuals self-reported dissatisfaction with their vision, 26.8% self-reported a previous ocular pathology, 26.3% had uncorrected refractive error, 25.6% were functionally visually impaired, 9.2% had at least one previous eye surgery or procedure, and 4.0% had nonrefractive visual impairment. Upon screening, 25.1% of homeless individuals had some type of ocular pathology, which included cornea and external eye diseases (13.4%), glaucoma (7.4%), cataracts (6.3%), retinal diseases (5.3%), ocular motility disorders (4.7%), trauma (2.3%), neuro-ophthalmological conditions (1.7%), and oculoplastic conditions (0.7%). Homeless adults had significantly more visual impairment (p < 0.001), uncorrected refractive error (p < 0.001), ocular pathology (p < 0.001), cataracts (p < 0.001), retinal pathology (p < 0.001), and neuro-ophthalmological conditions (p < 0.001) relative to children.

CONCLUSIONS

Visual impairment in homeless individuals is higher than the general population. Uncorrected refractive error is a leading cause of visual impairment in this population. Additionally, homeless adults have significantly more visual impairment and ocular pathology than homeless children. Future studies should also explore if these differences are consistent in developing countries and investigate ways to increase eye care access for homeless individuals.

Physical illnesses associated with childhood homelessness: a literature review

BACKGROUND

Childhood homelessness is a growing concern in Ireland [1] creating a paediatric subpopulation at increased risk of physical illnesses, many with life-long consequences [2].

AIM

Our aim was to identify and categorize the physical morbidities prevalent in homeless children.

METHODS

A review of the English-language literature on physical morbidities affecting homeless children (defined as ≤ 18 years of age) published from 1999 to 2019 was conducted.

RESULTS

Respiratory issues were the most commonly cited illnesses affecting homeless children, including asthma, upper respiratory tract infections, and chronic cough [3]. Homeless children were described as being at increased risk for contracting infectious diseases, with many studies placing emphasis on the risks of sexually transmitted infections (STIs) and HIV/AIDS transmission [4, 5]. Dermatologic concerns for this population comprised of scabies and head lice infestation, dermatitis, and abrasions [3, 6]. Malnutrition manifested as a range of physical morbidities, including childhood obesity [7], iron deficiency anemia [4], and stunted growth [8]. Studies demonstrated a higher prevalence of poor dental [7] and ocular health [9] in this population as well. Many articles also commented on the risk factors predisposing homeless children to these physical health concerns, which can broadly be categorized as limited access to health care, poor living conditions, and lack of education [3, 10].

CONCLUSION

This literature review summarized the physical illnesses prevalent among homeless children and the contributing factors leading to them. Gaps in the literature were also identified and included a dearth of studies focusing on younger children compared with adolescents. Further research into prevention and intervention programs for this vulnerable population is urgently needed.
