[Etiologies and risk factors of endophthalmitis].

Endophthalmitis is a serious disease with multiple aetiologies. Its development seems to be dependent upon various risk factors. Among 99 cases of endophthalmitis, 79% were secondary to intraocular surgery especially cataract surgery and perforating ocular trauma. To identify risk factors of post-cataract surgery endophthalmitis, we performed a case-control study: 55 cases and 269 controls were used. Five risk factors were identified: duration of the operative procedure longer than 60 min, suture dehiscence, persistence of lens mass, traumatic cataract and left eye operated. The importance of prevention of endophthalmitis by avoiding such risk factors is raised.

[Results of trabeculectomy in congenital glaucoma].

Congenital glaucoma has a very serious prognosis. It represents the first cause of blindness in Tunisian children. Trabeculectomy introduced by Cairns in 1968, was initially proposed as second-line treatment in congenital glaucoma surgery. It has now become more frequently used as first-line treatment in this indication. We have already used this technique directly in 35 children suffering from congenital glaucoma with a total of 54 eyes. Forty four eyes underwent a single operation, ten eyes underwent two to four trabeculectomies. Then study of these cases with a mean follow up of 24 months shows an overall success rate of 64% after one trabeculectomy, with or without additional medical treatment. The study of tonometric diagrams shows that the successful results obtained after 3 months persisted in the long term. Trabeculectomy gives better results in congenital glaucoma with intraocular pressure greater than 40 mmHg. Repeated operations are sometimes necessary. In these cases, postoperative subconjunctival 5 fluorouracil (SFU) did not improve the surgical outcome.

[The visual field of patients with pseudophakia using kinetic and automated perimetry].

One of the major benefits of pseudophakia is to maintain a good visual field. Visual field was therefore studied in 40 pseudophakic eyes using: 1. kinetic perimetry according to Goldmann using 3 tests: I1, I2, I4; 2. Automated perimetry. Insertion of a posterior chamber intraocular lens was performed in 85% of cases whereas the remaining 15% received an anterior chamber intraocular lens. Visual acuity was > 5/10 P2-P4 in all patients. The results showed a 15% reduction in the visual field compared to normal values. This reduction was concentric and harmonious but was more marked in internal isopters. This reduction was less marked with posterior chamber intraocular lenses. On the other hand, automated perimetry showed that global retinal sensitivity was decreased in pseudophakia, and this deficiency was more pronounced in the periphery.

[Developmental aspects of diabetic retinopathy during pregnancy].

The course of diabetic retinopathy (DR) was studied in 93 pregnant patients. Results were compared with data from 98 diabetic non pregnant women. Worsening of initial retinal lesions was observed in 16% of the pregnant group whereas only 6% of the control group showed a similar aggravation. The difference between the two groups was statistically significant (p < 0.05). Argon laser panretinal photocoagulation of pre-proliferative and proliferative DR resulted in no subsequent DR-induced complications. On the other hand, the risk of appearance of DR and/or its worsening during pregnancy depends on initial network but mostly on the duration of diabetes mellitus. In conclusion, regular ophthalmologic examination of diabetic patients especially during pregnancy seems crucial for the early screening of any worsening. Furthermore, the importance of pregnancy planning is emphasized.

[Senile cataract and trachoma in Tunisia].

Senile cataract is the major cause of curable blindness in Tunisia (51%). Other factors than advanced age seem to play a role in senile cataract. The simultaneous of senile cataract with the trachoma makes the surgical operation problematic. In order to evaluate the frequency of such risk factors, we have realized a prospective study in two groups of patients recruited in 4 hospitals centers in Tunisia. The two groups of patients were homogenous regarding to age (more than 45 old year) sex and geographic origins. Cataract was present in the first group (287), but not in the second group (169) risk factors which were evidenced are: diabetes or abnormal glucose test tolerance, high systemic blood pressure, especially diastolic, low education and non professional occupation, family history of cataract. Evolutive trachoma was found in 5.1% of cases compared to only 0.6% in controls (p = 0.02). Trachoma sequela were found in the two groups. The importance of an evaluation of such risk factors in senile cataract is raised.

[Epidemiological profile of primary open-angle glaucoma in Tunisia].

The main epidemiologic characteristics of primary angle glaucoma in Tunisia were studied in 5000 patients of Pr. AYED's external consultation at the National Institute of Ophthalmology. It appeared that POAG is a frequent and serious disease in Tunisia: a true problem of public health. The importance of the early diagnosis based essentially on a systematic intraocular pressure test together with the examination of optic disc and the visual field investigation using automated perimetry in suspected cases is discussed.

[Diabetes and color vision disorder detected by the Farnsworth 100 Hue test. Diabetic dyschromatopsia].

Farnsworth 100 Hue test was used to investigate color vision in 100 diabetic patients. Blue Yellow axis dyschromatopsia was found in 66.5% of patients. Such a dyschromatopsia precedes diabetic retinopathy in 55% of patients. Its frequency increased as a function of the increasing severity of diabetic retinopathy. On the other hand, 36% of the patients suffering from dyschromatopsia misinterpreted the self-monitoring (urine and blood) tests. These results suggest that the investigation of color vision may be a useful tool for the early screening of diabetic retinopathy particularly in self-monitoring patients.

[Primary open-angle glaucoma and diabetes].

UNLABELLED: Open-angle glaucoma is most frequent in diabetics. Its evolution seems to be most severe although an equilibrated tonometry under glaucoma treatment in literature. AIM OF THE STUDY: comparison of evolution of glaucoma between diabetics and non diabetics. MATERIAL AND METHODS: A retrospective study of 72 glaucomatous patients diabetic and non diabetic was performed. A complete ophthalmologic examination with tonometry, funduscopy: sup disc measurement and automated perimetry was realised. Evolution was studied after chirurgical or medical treatment each four months with a mean follow up of 2 years. RESULTS: We observed that the evolution of Open-angle glaucoma in diabetics is significatively not different from non diabetics. CONCLUSION: Open-angle glaucoma evolution in diabetics is not more severe than general population.

[Antiphosphoplipid antibodies and retinal occlusive vasculopathy].

PURPOSE: to determine the prevalence of antiphospholipid antibodies in patients with occlusive retinal vascular events, exempt from conventional risk factors of retinal thrombosis. METHODS: eleven patients with retinal vascular occlusion, free of main accepted risk factors for retinal thrombosis, were retrospectively screened for antiphospholipid antibodies (anticardiolipin and anti-beta2 glycoprotein 1 antibodies) by an Elisa method. Prevalence of antiphospholipid antibodies were compared with those in a homogenous control group of 100 patients. RESULTS: the prevalence of antiphospholipid antibodies in the study group was 27% (three of 11). Comparison with control group prevalence (3%) showed a statistically significant difference (p < 0,001). One patient in the study disclosed positivity for IgG anticardiolipine antibodies, one for IgM anticardiolipine antibodies and one for anti-beta2 glycoprotein 1 antibodies. CONCLUSION: our results lead us to recommend a systematic search for specific antiphospholipid antibodies in such young patients which could have an importance for the diagnosis of primary antiphospholipid syndrome.
