[Full optical correction after cycloplegia in headache].

PURPOSE: To study the advantages of cycloplegia in the accurate assessment of refractive errors and to evaluate the impact of full optical correction in the course of headache. MATERIAL: and methods: A prospective study was carried out in 164 eyes of 82 patients with headache. Corrected visual acuity was 10/10 in all cases. Refraction was measured before and under cycloplegia by cyclopentolate with a CANON R 50 infrared autorefractometer. Full optical cycloplegic correction based on the value of refraction under cycloplegia was prescribed in all cases. Mean follow-up was 10 months. Statistical analyses were used: Student's t test, Pearson coefficient correlation, and Chi2. RESULTS: Under cycloplegia, hypermetropia was significantly the most frequent ametropia (67.1%, p<10(- 9)). The difference between the spherical equivalent, before and during cycloplegia, was highly significant (p<10(- 5)) at 0.79. Optical correction eliminated headaches in 76.5% of the cases. CONCLUSION: The authors conclude on the role of accommodation in headache onset and the need to continue cycloplegia until the age of 45. The importance of optical correction in alleviating headaches is underlined.

[Diabetes and the day hospital].

The day hospital is a relatively new way of hospitalization in Tunisia, the first experience beginning in 1985 to the National Institute of Nutrition. This hospitalization avoid the drawbacks of classic hospitalization (dependency, discomfort, separation) and boredom and present a lot of advantages of social command, humanitarian, psychological, medical and economical the cost of hospitalization is clearly reduced). This day hospitalization is beneficial in several pathologies notably the illness nutrition and metabolic diseases (diabetes, obesity, dyslipoproteinemia, hyperuricemia), where the patients continue to have a good physical activity and where the education médico sanitary and dietary hygiéno occupies a position of choice.

[Quantitative topographic detection of keratoconus in the contralateral eye in clinically unilateral keratoconus. Apropos of 5 cases].

BACKGROUND: Keratoconus is generally bilateral and follows an asymmetrical course. The goal of this study was to evaluate efficiency of the automated topographic screening indices on early keratoconus by examination of the fellow eyes of clinically unilateral keratoconus. PATIENTS AND METHOD: We examined the fellow eyes of 5 cases of clinically unilateral keratoconus by videokeratography using TMS-1 Computed Anatomy device, which incorporates the keratoconus screening indices from Rabinowitz (K and I-S values) and Klyce/Maeda (KPI value and other quantitative induces as OSI, DSI and CSI). RESULTS: One case (number 1) had keratoconus detected by both Rabinowitz and Klyce/Maeda indices. Two cases (number 2 and 3) had normal keratoconus screening indices. Two cases (number 4 and 5) had keratoconus detected by Rabinowitz I-S value, with a 0% KPI value. CONCLUSIONS: Rabinowitz indices are sensitive with a poor specificity. The Klyce/Maeda indices are less sensitive but more specific. Both methods may be useful for keratoconus detection. The results must always be analysed in relation to a clinical observation of both eyes and the course of the topographic changes.

[The cornea of diabetics].

PURPOSE: The aim of the study is to investigate corneal sensitivity and the risk factors of corneal hypoesthaesia in diabetics. METHODS: General examination and full ophthalmologic examination completed by exploration of corneal sensitivity were performed in one hundred thirty diabetic patients. RESULTS: Eleven per cent of patients showed microkystic oedema, whereas corneal hypoesthaesia was found in 45% of cases. Corneal hypoesthaesia was correlated with the duration and balance of diabetic mellitus, the age of patients and the presence of diabetic retinopathy. On the other hand, peripheral neuropathy was found in 88% of cases. CONCLUSION: Ophthalmologic examination of diabetics should not be limited to retina only but should also include the entire eye ball and especially the cornea in patients with high risk.

[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.
