Risk factors for open-angle glaucoma: a case-control study.

The objective of this study was to identify possible risk factors associated with open-angle glaucoma (OAG). A case-control study included patients seen at an ophthalmologic clinic. Cases were all consecutive new patients with either unilateral or bilateral OAG detected during the study period. Controls were a random sample of all other patients aged 30 or more, seen in the same department in the same period. Data on demographic, anthropometric and diet habits as well as medical characteristics were collected from 144 patients by medical examination and interview. The study took place at the University Department of Ophthalmology and general private practice of ophthalmology, both in the city of Kinshasa. Forty consecutive patients with OAG and 104 controls were chosen randomly between all consecutive non OAG patients. Odds ratio (OR) are presented for the relation between OAG and age, sex, ethnicity, family history of glaucoma, the length of stay in Kinshasa, body mass index, hypertension, diabetes mellitus, cigarette smoking, alcohol, diet habits. Adjusted odds ratio resulting from stepwise logistic regression was employed. Results indicate: family history of glaucoma (OR, 18; 95% CI, 5.80-59.00; P < 0.001), age (OR, 1.05; 95% CI, 1.01-1.09; P = 0.025), body mass index (OR, 1.09; 95% CI, 1.01-1.18; P = 0.05), hyperopia (OR, 2.9; 95% CI, 1.05-7.08; P = 0.03), Mongo ethnic group (OR, 3.5; 95% CI, 1.11-12.20; P = 0.03) and consumption of rice (OR, 4.6; 95% CI, 1.65-12.20; P = 0.004) conferred a significantly greater risk of OAG. This study seems confirm that Mongo ethnic group is associated with an increased risk of OAG.

[Solar retinopathy acquired after gazing at the sun during prayers].

The authors present the results of a study based on six persons who developed retinopathy after gazing at the sun during prayers. Risk factors were studied and the prognosis evaluated. The mean follow-up time was 82 days. Risk factors were present in all patients. The visual acuity was reduced in all patients at first presentation and total improvement was noted in four of them. Of all six patients, only one had his ocular fundus normalized. Amsler's grid testing revealed in all patients bilateral central scotomas which persisted in four of them. Fluorescein retinal angiography, which was found to be abnormal in all cases, became normal in only one case. However, all patients continued to complain of visual disability because of the persistence of photophobia, meta-morphopsia and scotomas. In conclusion, the prognosis of solar retinopathy is variable and the recovery of visual acuity does not necessarily imply the improvement of vision. Appropriate eye protection such as solar filters must be used when gazing at the sun to protect from retinal damage.

[Ocular complications in diabetes mellitus in Zaire].

OBJECTIVE: to determine the incidence of ocular complications of diabetes in Zaïre. METHODS: the study was based on an analysis of data from 382 diabetic patients seen from 1978 through 1989, and from Jan. 1990 through April 1990. Ocular complications were determined by routine ophthalmic examination including an inspection of adnexa, biomicroscopy, ophthalmoscopy. RESULTS: the average age of patients was 46 years the male to female ratio being 2:1. Ocular complications were found in 200 (52%) of 382 patients and included diabetic retinopathy (32%), cataract (18%) and other manifestations (vitreous hemorrhage, diabetic papillopathy, neovascular glaucoma, rubeosis iridis, keratitis, hordeolum) were rare (2%). Blindness caused by diabetes mellitus was found in 4% of patients and was due to diabetic retinopathy and cataract. CONCLUSION: Ocular complications seen in this study were comparable to those reported in Africa and the World.

[Traumatic hyphema caused by contusion in Zaire].

PURPOSE: To study the clinical characteristics of hyphema. METHODS: Records of all 57 consecutive patients with traumatic hyphema due to non perforating ocular injury seen during a ten-year period (from 1982 to 1991) were reviewed. All patients were outpatients and were treated with topical application of corticosteroids with or without topical application of 0.5 or 1% atropine sulfate and antibiotics. For an intraocular pressure greater than 24 mmHg, topical timolol maleate 0.5% and, if necessary, oral acetazolamide sodium were used. RESULTS: There were 49 (86%) male and 8 (14%) female for sex ratio of 6:1. The average age of patients was 20.2 years (range, 2 to 61 years). Blows were responsible for injury in 53%; projectiles for 30% and explosions for 7% of all hyphemas. The most common associated injuries to the eye included cornea edema (40%), cataract (36%) and mydriasis (26%). Posterior synechiae (25%) and blood staining of the cornea (22%) were the most frequent complications that occurred. Secondary haemorrhage occurred in 7% of the cases. CONCLUSIONS: Heavily pigmented eye, proptosis, paucity of facilities for care may be responsible of the high rate of complications.

[Myelin fibers in Zairian patients].

PURPOSE: to determinate the characteristics of myelinated nerve fibres in Zairian blacks patients. METHODS: a review of records of patients with myelinated nerve fibers seen from 1962 to 1994. RESULTS: the relative incidence of myelinated nerve fibers was 0.02%. There were 13 (76%) male patients and 4 (24%) female patients. The average age at the moment of diagnosis was 32 years (range, 7 to 61 years). Myelinated nerve fibers were bilateral in 8 (47%) patients (16 of 25 eyes, 64%) and unilateral nerve fibers, 21 (84%) eyes contained a single lesion and 4 (16%) eyes contained multiple separate and distinct patches of myelinated fibers. Continuous lesions were present in 21 (84%) eyes and discontinuous lesions in 4 (16%) eyes. The 25 affected eyes varied in refractive error from a spherical equivalent of + 1.5 to - 16.00. The distribution of refraction was: emmetropia in 2 (12%) patients (2 eyes, 8%), simple myopia in 4 (24%) patients (5 eyes, 20%), myopia over 6 D with amblyopia in 6 (35%) patients (10 eyes, 40%), hypermetropia in 5 (29%) patients (8 eyes, 32%). CONCLUSION: this study showed a low relative incidence of myelinated nerve fibers and the bilaterality of lesions was frequent.

[Exophthalmias in Zaire].

PURPOSE: To determinate the frequencies of causes of exophthalmos in Zaïre. METHODS: In a retrospective study, the records of 129 patients with exophthalmos seen from 1986 to 1994 were reviewed. All patients were examined ophthalmologically and most of them medically. X-Rays, orbital CT Scan, were performed most frequently. RESULTS: The sex distribution was: 79 (61%) male patients and 50 (39%) female patients. The sex ratio being 1.50/1. The ages of patients ranged from one to 68 years. Unilateral exophthalmos was frequent (76% of cases). Tumors were present in 42% patients, followed by inflammatory diseases in 26% of patients, thyroid eye disease in 9% and traumatic aetiology in 1.6%; the etiology was not determined in 14%. Retinoblastoma (8%), lymphoma (7%) and rhabdomyosarcoma (5%) were the most frequent tumors seen. Orbital cellulitis (26%) was frequently associated with adjacent sinus infection. CONCLUSION: The etiologic factors found in this study could be compared to those published in the World with the exception of orbital cellulitis and retinoblastoma that showed a high incidence in this study.

[Orbital measurements in Zairian children. Inner canthal, outer orbital, inter-pupillary distances and proptosis].

Measurements of outer orbital distance, inner canthal distance and of interpupillary distance and proptosis were performed on 95 healthy Zairian subjects. The subjects were aged from 2 1/2 to 18 years. There were 47 boys (mean age +/- SD, 9.74 +/- 4.4 years) and 48 girls (mean age +/- SD, 9.07 +/- 4.1 years). No statistically significant difference was found between the two sexes for the mean age. Subjects were divided in four age groups: the first age group included children aged from 2 1/2 to 6 years (mean age +/- SD, 4.62 +/- 1.31 years), the second age group included children aged from 7 to 10 years (mean age, 8.32 +/- 1.22 years), the third included subjects aged from 11 to 14 years (mean age +/- SD, 12 +/- 1.06 years) and the fourth included subjects aged from 15 to 18 years (mean age +/- SD, 17 +/- 3 years). The measurements were performed with the Hertel exophthalmometer for the proptosis and the outer orbital distance, with the pupillometer model PD-2 meter for the interpupillary distance; with a ruler for the inner canthal distance. The mean +/- SD inner canthal was 27.4 +/- 2.7 mm for the first age group, 29.7 +/- 3.1 mm for the second age group, 30 +/- 2.4 mm for the third age group and 32.2 +/- 3.1 mm for the fourth age group. The mean +/- SD outer orbital was 100.0 +/- 4.4 mm for the first age group, 106.5 +/- 4.6 mm for the second age group, 111.7 +/- 6.8 mm for the third age group and 118.5 +/- 6.4 mm for the fourth age group.(ABSTRACT TRUNCATED AT 250 WORDS)
