RESUMO

Purpose: To evaluate the clinical and socio-demographic profile of patients living with glaucoma and receiving care in a tertiary eye center in Zimbabwe. Method: A hospital-based retrospective study of clinical records of glaucoma patients from January 2014 to December 2018. The study involved collating demographic information of patients, visual acuities, (VA) intraocular pressure, (IOP), cup-to-disc ratios, (CDRs), average retinal nerve fibers thickness, (RNFL), cup volume, cup-to-disc area, vertical cup-to-disc ratio, (VCDR), rim area, disc area, glaucoma hemifield test, visual field indices and the management of glaucoma. Results: Nine thousand one hundred and eighty-five (9,185) folders were retrieved. Out of these, 432 (4.7%) qualified for the study and were analyzed. There were 267 (61.8%) males and 165 (38.2%) females. The mean age (± Standard deviation, SD) of the patients was 62.66 ± 15.94 years, (range 10 - 110 years). The means visual acuity (VA): OD =1.30 ± 1.06 Logarithm of the Minimum Angle of Resolution, (logMAR), OS = 1.33 ± 1.06 logMAR; IOP: OD = 29.51 ± 12.89 mmHg, OS: 29.17 ± 12.59 mmHg; CDRs: OD = 0.91 ± 0.14 D, OS = 0.92 ± 0.14 D; and the average RNFL thickness was 72.76 ± 18.26 µm and 71.24 ± 23.17 µm in the right and left eye respectively. The mainstay of treatment was medication only. Conclusion: There were more males than females receiving glaucoma care at the tertiary level. Glaucoma cases included juveniles but the mean age was mostly the elderly. It was characterized by high IOPs, large CDRs, and thin RNFL suggestive of late presentation.

RESUMO

Purpose: To determine the prevalence of visual impairment attributable to refractive error and other causes in a youthful Ghanaian population. Methods: A prospective survey of all consecutive visits by first-year tertiary students to the Optometry clinic between August, 2013 and April, 2014. Of the 4378 first-year students aged 16-39 years enumerated, 3437 (78.5%) underwent the eye examination. The examination protocol included presenting visual acuity (PVA), ocular motility, and slit-lamp examination of the external eye, anterior segment and media, and non-dilated fundus examination. Pinhole acuity and fundus examination were performed when the PVA≤6/12 in one or both eyes to determine the principal cause of the vision loss. Results: The mean age of participants was 21.86 years (95% CI: 21.72-21.99). The prevalence of bilateral visual impairment (BVI; PVA in the better eye ≤6/12) and unilateral visual impairment UVI; PVA in the worse eye ≤6/12) were 3.08% (95% CI: 2.56-3.72) and 0.79% (95% CI: 0.54-1.14), respectively. Among 106 participants with BVI, refractive error (96.2%) and corneal opacity (3.8%) were the causes. Of the 27 participants with UVI, refractive error (44.4%), maculopathy (18.5%) and retinal disease (14.8%) were the major causes. There was unequal distribution of BVI in the different age groups, with those above 20 years having a lesser burden. Conclusion: Eye screening and provision of affordable spectacle correction to the youth could be timely to eliminate visual impairment (AU)


Objetivo: Determinar la prevalencia de la deficiencia visual atribuible al error refractivo y a otras causas en una población de jóvenes de Ghana. Métodos: Estudio prospectivo de todas las visitas consecutivas realizadas por estudiantes terciarios de primer año que acudieron a la Clínica de Optometría entre Agosto de 2013 y Abril de 2014. De los 4.378 estudiantes de primer año registrados, de edades comprendidas entre 16 y 39 años, 3.437 (78,5%) se sometieron a un examen ocular. El protocolo del examen incluyó la revisión de la agudeza visual (AV), la motilidad ocular y la biomicroscopía del ojo externo, segmento anterior y medio, y el examen del fondo de ojo sin dilatación. Los exámenes de la agudeza con agujero estenopeico y del fondo de ojo se realizaron en aquellos casos de AV ≤ 6/12 en uno o ambos ojos para determinar la causa principal de la pérdida de visión. Resultados: La edad media de los participantes fue de 21,86 años (95% IC: de 21,72 a 21,99). La prevalencia de la deficiencia visual bilateral (BVI; AV en el mejor ojo ≤ 6/12) y la deficiencia visual unilateral (UVI; AV en el peor ojo ≤ 6/12) fue del 3,08% (95% IC: de 2,56 a 3,72) y el 0,79% (95% IC: de 0,54 a 1,14), respectivamente. En 106 participantes con BVI, las causas principales fueron el error refractivo (96,2%) y la opacidad corneal (3,8%). De los 27 participantes con UVI, el error refractivo (44,4%), la maculopatía (18,5%) y la enfermedad retiniana (14.8%) fueron los principales motivos. Se produjo una distribución desigual de la BVI en los diferentes grupos de edad, habiendo un menor impacto en aquellos participantes con edades superiores a 20 años. Conclusión: La exploración ocular y la adaptación de una corrección en gafa asequible en los jóvenes podría eliminar a tiempo la deficiencia visual (AU)
