Título: Filtration surgery in Black patients: early results in a West Indian population
Fonte: Ophthalmic Surg;18(3):195-9, Mar. 1987.
Idioma: En.
Resumo: We reviewed the early results of 80 filtration procedures when used as the initial surgical treatment in a Saint Lucian West Indian black population with primary open angle glaucoma. Two techniques were used: trabeculectomy under a scleral flap with fornix-based conjunctival flap (Group 1) and full thickness posterior lip sclerectomy with limbal-based conjunctival flap (Group 2). Postoperatively, with an average follow-up of six months, Group 2 had significantly lower intraocular pressures, reduced glaucoma medication requirements, and increased cystic pleb formation. Vision did not differ significantly between the two groups postoperatively, although two Group 1 patients developed progressive glaucomaous visual loss. Complications were slightly more frequent in Group 2. The results of this study suggest that a full thickness sclerectomy technique merits consideration as the initial filtration procedure of choice in West Indian blacks with advanced open angle glaucoma.(AU)

Título: A pilot project of glaucoma in Barbados
Fonte: Br J Ophthalmol;73(5):365-9, May 1989.
Idioma: En.
Resumo: The prevalence of open-angle glaucoma is believed to be very high among West Indian blacks. To begin investigating the prevalence and risk factors for glaucoma and other eye diseases in Barbados, WI, a pilot study was conducted. The pilot project identified a stratified, random national sample of 300 persons over 35 years of age who were invited to participate in an ophthalmic examination and an interview. Of those contacted 89 percent were eligible and 95 percent of these agreed to participate. The overall glaucoma prevalence in the participants was 6 percent; it was 13 percent among black and mixed persons over 54 years. Age related cataract, hypertension, and diabetes were frequent findings. Although the sample size of the pilot project is small, the results suggest a high prevalence of glaucoma in Barbados, a finding that merits further study. (AU)

Título: Posterior lip sclerectomy vs trabeculectomy in West Indian Blacks
Fonte: Arch ophthalmol;107(11):1604-8, Nov. 1989.
Idioma: En.
Resumo: Surgical treatment in a West Indian black population with primary open angle glaucoma was randomized to full-thickness posterior lip sclerectomies or partial thickness trabeculectomies. Forty-five posterior lip sclerectomies and 35 trabeculectomies were performed. With a mean follow-up period of 28.3 months, the eyes with posterior lip sclerectomies had lower intraocular pressures, reduced glaucoma medication requirements, and less failures. Decline of visual acuity did not differ significantly between the two groups, but early visual acuity loss due to accelerated cataract formation was noted more frequently with posterior lip sclerectomies. The incidence of flat anterior chambers also did not differ significantly, but shallow anterior chambers were more frequent and persisted for a longer time with posterior lip sclerectomies. Other complications were more frequent with posterior lip sclerectomies. (AU)

Título: The Barbados eye study
Fonte: Arch Ophthalmol;112(6):821-9, June 1994.
Idioma: En.
Resumo: OBJECTIVE: To describe the design of the Barbados Eye Study and report of the prevalence of open angle glaucoma (OAG) in a predominantly black study population. DESIGN: Population-bases prevalence study. SETTING AND PARTICIPATION: Residents of Barbados, West Indies, identified from a simple random sample of Barbadian-born citizens 40 through 84 years old. DATA COLLECTION: Participants had a comprehensive study visit that included automated perimetry, applanation tonometry, and fundus photography; persons with specific findings, as well as a 10 percent sample of participants, were referred for an ophthalmologic exanimation and additional tests. OUTCOME: A diagnosis of OAG required both visual field and optic disc criteria for glaucoma damage after excluding other causes. RESULTS: The 4709 participants (83.5 percent of those eligible) had demographic characteristics that were similar to the census population. Of the 4631 participants who were tested at the study site, 95 percent completed Humphrey automated perimetry and 97 percent had photographic or clinical disc gradings; 93 percent of those referred completed the ophthalmologic examination. In the adult population, the prevalence of OAG by self-reported race was 7.0 percent (302/4314) in black, 3.3 percent (6/184) in mixed race, and 0.8 percent (1/1`33) in white or other participants. In black and mixed-race participants, the prevalence reached 12 percent at age 60 years and older and was higher in men (8.3 percent) than in women (5.7 percent), with and age-adjusted male-female ratio of 1.4. In addition, over 3 percent of the participants were classified as having suspect OAG. CONCLUSIONS: To our knowledge, the Barbados Eye Study is the largest glaucoma study ever conducted in a black population and identified more people with OAG than did any previous population study. The prevalence of OAG was high, especially at older ages and in men. Among participants 50 years old or older, one in 11 had OAG, and prevalence increased to one in six at age 70 years or older. The results highlights the public health importance of OAG in the Afro-Caribbean region and have implications for other populations. (AU)

Título: Risk factors for open-angle glaucoma: the Barbados eye study
Fonte: Arch Ophthalmol;113(7):918-24, July 1995.
Idioma: En.
Resumo: The objective was to evaluate risk factors for open-angle glaucoma among black participants in the Barbados Eye Study. The design was a population-based study of demographic, medical, ocular, familial, and other factors possibly related to open-angle glaucoma. The setting and participants: The Barbados Eye Study included 4709 Barbados residents identified by a simple random sample of Barbadian-born citizens, 40 to 84 years of age; participation was 84 percent. This report is based on the 4314 black participants examined at the study site; 302 (7 percent) met the Barbados Eye Study criteria for open-angle glaucoma. Data collection included a standardized protocol included applanation tonometry, Humphrey perimetry, fundus photography, blood pressure, anthropometry, and an interview. An ophthalmologic examination was performed for participants who met specific criteria. Main outcome measures: open-angle glaucoma was defined by the presence of both characteristics visual field defects and optic disc damage. Association of open-angle glaucoma with specific factors was evaluated in logistic regression analysis. Results: age, male gender, high intraocular pressure, and family history of open-angle glaucoma were major risk factors; the latter association was stronger in men than women. Lean body mass and cataract history were the only other factors related to open-angle glaucoma. Although hypertension and diabetes were common in Barbados Eye Study participants, they were unrelated to the prevalence of open-angle glaucoma. However, associations were found with low diastolic blood pressure-intraocular pressure differences and low systolic and diastolic blood pressure/intraocular pressure ratios. The Conclusions: In the Barbados Eye Study black population, persons most likely to have open-angle glaucoma were older men and had a family history of open-angle glaucoma, high intraocular pressure, lean body mass, and cataract history. These results suggest the importance of possible genetic or familial factors in open-angle glaucoma. The role of vascular risk factors is consistent with our finding of low blood pressure to intraocular pressure relationships, but the results could be explained by the high intraocular pressure in open-angle glaucoma (AU)

Título: Analyses of reported family history of glaucoma: a preliminary investigation: the Barbados Eye Study Group
Fonte: Opthalmic Epidemiol;3(3):135-41, Dec. 1996.
Idioma: En.
Resumo: This study investigated the self-reported family history of open-angle glaucoma (OAG) among 4,314 black participants in the Barbados Eye Study (BES), which was based on a random sample of Barbados-born citizens between 40 and 84 years of age. Data collection included Humphrey perimetry, fundus photography various ophthalmic and other measurements and a comprehensive interview, including family history. Results showed that participants with OAG and previus OAG treatment reported more family history; maternal history was repored twice as often as paternal history. In persons without previous OAG treatment, those with newly diagnosed OAG reported more sibling history (Odds Ratio = 4.5). The Statistical Analysis for Genetic Epidemiology (S.A.G.E.) system was used to test the transmission models for OAG in a subset of 1,048 families (5,806 individuals) with the most complete self-reported family information. The S.A.G.E. results are consistent with the existence of a major dominant allele for OAG. These results should be viewed as promising, but preliminary, since they are based on self-reported data. More definitive information is currently being collected by the Barbados Family Study of Open-angle Glaucoma.(AU)

Título: Distribution of intraocular pressure: the Barbados Eye Study
Fonte: Arch Opthalmol;115(8):1051-7, Aug., 1997.
Idioma: En.
Resumo: OBJECTIVE: To provide data on the distribution of intraocular pressure (IDP) in a predominantly black population, which has a high prevalence of open-angle glaucoma. DESIGN: Population-based prevalence study. SETTING AND PARTICIPANTS: Participants (N = 4601) (age range, 40-84 years) who had undergone applanation tonometry measurements in the Barbados Eye Study. Self-reported race was 93 percent black, 4 percent mixed (black and white), and 3 percent white or other. DATA COLLECTION: A standardized protocol included applanation tonometry and other ocular measurements, fundus photography, demographic data, and an interview. MAIN OUTCOME MEASURES: The average of 3 IDP measurements at the Barbados Eye Study visit was used to compare IDP by self-reported race. Descriptive data on IDP by age, sex, glaucoma status, and cup-disc ratio were examined in the black population. RESULTS: The IDP was highest in the population of African origin. The mean (+/-SD) IDP values for black, mixed, and white participants were 18.7 +/- 5.2, 18.2 +/-3.8, and 16.5 +/- 3.0 mm Hg, respectively. An IDP greater than 21 mm Hg was present in 18.4 percent, 13.6 percent and 4.6 percent of the black, mixed and white participants, respectively. In analyses that were adjusted for age, sex, and glaucoma status, such values were 5 times as likely in black than white participants and 3.5 times as likely in mixed race participants (p < .01). Among the black participants, the mean IDP increased approximately 1 mm Hg for every increase in 10 years of age. After excluding persons with any type of glaucoma, suspected glaucoma, or a history of glaucoma treatment, women had significantly (P < .01) higher IDP values; however, no significant IDP trends by sex were evident in the group with glaucoma. The IDP was also positively associated (P < .05) with vertical cup-disc ratios. After 2 visits, the IDP remained 21 mm Hg or less in 21 percent of the persons with glaucoma vs 64 percent of those without glaucoma. CONCLUSIONS: In the black participants, the IDP was higher than in the white participants. The IDP was also associated with age and cup-disc ratios. The results showed that open-angle glaucoma and a high IDP alone have a different distribution by sex; although open-angle glaucoma was more frequent in men, ocular hypertension was more frequent in women. These data have implications for the detection and causation of open-angle glaucoma in this high-risk population.(AU)

Título: Diagnosis and management of a silent blinding disease in melanoderms: chronic (primary) open angle glaucoma
Fonte: West Indian med. j;47(Suppl. 3):23, July 1998.
Idioma: En.
Resumo: In melanoderms it is estimated that over 10 percent of the adult population is afflicted with open angle glaucoma. This disease is painless, chronic and gradually reduces vision leading eventually to blindness. There is no cure but with early diagnosis, patient education and treatment glaucoma is controllable. The anatomy, physiology, and pharmacology of the eye will be discussed. Surgical management will also be discussed as well as the social and economic effects of this disease in developing countries.(AU)

Título: Prevalence of open angle glaucoma in a diabetic population in Martinique
Fonte: West Indian med. j;49(suppl. 3):17, July 2000.
Idioma: En.
Resumo: OBJECTIVE: To determine the prevalence of open angle glaucoma in a hospital-based sample of diabetic people living in Martinique. DESIGN: Retrospective study during 23 months. PARTICIPANTS: A total of 917 patients were examined and received a complete eye examination for diabetes. MAIN OUTCOME MEASURES: A form was established with all examination data, patient ID, non ophthalmological data (blood pressure, body mass index, type of diabetes...) and ophthalmological data with intra-ocular pressure and optic disc cup. RESULTS: Glaucoma was present in about 9.8 percent of patients and there were 3.28 times more females than male. With regard to the type of diabetes, 1.11 percent were type 1, 18.89 percent were type 2, and 80 percent were insulin treated but not all insulin dependent. The prevalence of diabetic retinopathy is similar in the glaucomatous group and in the non-glaucomatous group. High blood pressure was present in 80 percent of glaucoma patients versus 58.8 percent in the non-glaucoma group. CONCLUSION: This 9.8 percent prevalence of glaucoma is the only data on open angle glaucoma so far available in Martinique. High blood pressure is a main risk factor for glaucoma in Martinique. Diabetes represents also a risk factor for glaucoma in Martinique. The sex ratio showed 3 times more females than males in the diabetic population. (AU)
