“…[2][3][4][5] Although medical treatment for glaucoma remains a common first-line option in developed areas, lack of availability and cost of medications make this modality less practical 6 in areas of limited resources. For these reasons, glaucoma surgery, such as trabeculectomy, may be preferred 7,8 as initial treatment for glaucoma in rural areas of lower-and middleincome countries (LMICs).…”

“…36 On the other hand, glaucoma was diagnosed in 5.4% of the studied population, higher than the calculated worldwide prevalence (3.54%) for 40-80 years old populations. [37] Other features of the eye that may indicate asymptomatic evolution of glaucoma (intraocular pressure, cup-to-disc ratio, central corneal thickness) were within normality range.…”

Purpose: To report ophthalmological findings from one quilombo remnant population, a Brazilian marginalized rural and slave-descendant community.Methods: Descriptive study of eye health from one of the largest quilombo communities in Brazil, located in Conceição das Crioulas, Pernambuco. Ophthalmic exam including visual acuity, refractive examination, biomicroscopy, fundus examination, tonometry and pachymetry was performed in a convenience sample of 255 residents over 40 years-old, representing approximately one third of the population in this age range.Results: Half of the subjects had never been examined by an ophthalmologist in their lives. Blindness was identified in 6.7% of participants and low vision in 8.6%. Visual impairment was caused mainly by cataract and uncorrected refractive errors. Cataract was found in 27.3% of subjects. Ametropia was documented in 71% of participants and the most prevalent refraction error was hyperopia. Prevalence of glaucoma and age-related macular degeneration were respectively 5.4% and 1.9%. Pterygium was detected in 26.7% of participants. Correcting lenses were prescribed to 57.4% of individuals, 5.5% were referred for surgery, 2.7% to specialized clinics and 1.2% to additional tests. Conclusions:Blindness, cataract and pterygium were highly frequent in quilombo residents, and distribution of other ocular diseases were close to average published rates. Data collected may help planning preventive and promotive actions for eye health of socioeconomic disadvantaged quilombo populations.

“…Among them, glaucoma is the leading cause of irreversible blindness globally. The number of people with glaucoma worldwide will increase to 111.8 million in 2040 based on a report [3], disproportionally affecting Asian and African people. Because glaucoma may be asymptomatic until a relatively late stage, diagnosis is often delayed [4].…”

Optic nerve head (ONH) is a crucial region for glaucoma detection and tracking based on spectral domain optical coherence tomography (SD-OCT) images. In this region, the existence of a "hole" structure makes retinal layer segmentation and analysis very challenging. To improve retinal layer segmentation, we propose a 3D method for ONH centered SD-OCT image segmentation, which is based on a modified graph search algorithm with a shared-hole and locally adaptive constraints. With the proposed method, both the optic disc boundary and nine retinal surfaces can be accurately segmented in SD-OCT images. An overall mean unsigned border positioning error of 7.27 ± 5.40 µm was achieved for layer segmentation, and a mean Dice coefficient of 0.925 ± 0.03 was achieved for optic disc region detection.
