[Frequency of retinal changes in myopia in a black population]. / Fréquence des lésions rhegmatogènes chez le myope mélanoderme.

PURPOSE: Retinal detachment is the main complication of peripheral retinal lesions in myopia but seems rare in black people. We analysed peripheral retinal changes in myopia in a black population. MATERIAL AND METHODS: This study was conducted by a single ophthalmologist. The tests included a refraction, a retinal biomicroscopy (with a Volk lens and a 3-mirror Goldmann lens) and an indirect ophthalmoscopy. The results were compared by a chi square test. RESULTS: 50 people (100 eyes) were available for examination. The mean age was 28.21 years, the two extremes being at 11 and 54 years, with 68% females and 32% males. In 50 eyes the spheric equivalent was between -1 and -5.75 diopters (group I). In 50 eyes the spheric equivalent was greater than or equal to -6 diopters (group II). Snow was found in 16% of cases in group I and 34% of cases in group II (p = 0.0366). Tears were found in 2% of cases in group I and 12% of cases in group II (p = 0.116). Lattice degeneration was found only in group II. CONCLUSION: Retinal tear frequency was similar to the results of other authors. Comparative studies are necessary to evaluate the risk of retinal detachment in black populations.

[Compliance of medical treatment in primitive glaucoma open angle]. / L'observance au traitement médical dans le glaucome primitif à angle ouvert. Résultats préliminaires.

INTRODUCTION: Compliance to medical treatment expresses the patient's perception of the disease and the treatment prescribed by the doctors. Lack of compliance endangers chronic glaucoma care, which explains the importance it has been given these last years. The objectives of this survey were to evaluate the compliance of adult patients suffering from primary open angle glaucoma to discover the influential factors. MATERIALS AND METHODS: We conducted a survey at the ophthalmology clinic of Le Dantec Hospital from January 1997 to May 1998 among 31 adults being treated for primary open angle glaucoma. An indirect evaluation of the patients' compliance was made on the basis of a questionnaire after examination of their medical files. It was deemed good, average, or bad depending on: regularity of the patient's visits to the doctors, regularity of the treatment, respect of the doctor's prescription and the prescribed times for taking the medicine. The Chi square independence test was used to study the influence of the following factors: age, sex, residence, socioeconomic status, duration of symptom progression, level of instruction, counseling, and treatment. RESULTS: The patients' mean age was 60.5 years. Compliance was deemed good for 29% of the total cases, average for 32.3%, and bad for 38.7%. Only factors such as the regular visits to the doctor, the regularity of the treatment, and respect of the doctor's prescription and the prescribed times for taking the medicine were found to be influential (p<0.05). CONCLUSION: The medical treatment of primary open angle glaucoma, whether temporary or permanent, with a maximum of efficacy and a minimum of side-effects requires good compliance on the part of the patient. This compliance in turn requires a good doctor-patient relationship based on effective repeated counseling to educate patients, help them understand the disease, and act on the influential factors.

[Apropos of a case of incomplete cryptophthalmos]. / A propos d'un cas de cryptophtalmie incomplète.

A rare case of the cryptophtalmos syndrome is presented. It's an atypical form according to François' classification. There are three types of cryptophtalmos. The problems of surgical management using several operations are underlined.

[Essential atrophy of the iris apropos of 1 case]. / Atrophie essentielle de l'iris a propos d'une observation.

The authors report a case of bilateral essential iris atrophy syndrome in a twenty two years old man associated with unilateral cataract and glaucoma. They stress the rarity of the syndrome (first case in their section) and the uncommon bilateral case. The cataract unusually described in the syndrome would be directly linked to the important and durable ocular hypertension.

[Idiopathic serous retinal pigment epithelial detachment (a case report)]. / Le décollement séreux idiopathique de l'épithélium pigmentaire de la retine (a propos d'un cas).

Retinal pigmented epithelium detachment is frequently associated to age related macular degeneration or others maculopathies. More rarely no cause can be found, particularly in young patients where it constitutes an entity named "Idiopathic serous detachment of the retinal pigmentary epithelium". We report such a case. We insist on the clinical and angiographical characteristics which allows a differentiation from the idiopathic central serous chorioretinopathy with which it can be confused. Last, it is important to point that for the time being no treatment can shorten the evolution.

[Analysis of implant position after envelope technique in "white" cataract surgery]. / Analyse de la position de l'implant après technique de l'enveloppe dans la chirurgie de la cataracte "blanche".

Capsulopunture in cataract surgery doesn't allow insertion of intraocular lens in the capsular bag. Envelope technique is a easy way for this insertion. The goal of our study was to analyse the position of the intraocular lens in the capsular bag, after performing envelope technique in eyes suffering from "white" cataract. We realised on 25 eyes with "white" cataract, envelope technique. GALAND method (one superior linear capsulotomy) was realised in 15 cases and double linear capsulotomy (superior and inferior), was realised in 10 cases. The mean age of our patients was 55 years with two extremes (17 and 70 years). The mean visual acuity was 14/20. After verification, in 91.636% eyes, intraocular lenses were in the capsular bag. In 2 cases, we found a decentration. Envelope technique can lessen risks of capsular zip. It protects endothelium cells and is helpful for the insertion of the intraocular lens in the capsular bag. Envelope technique is well adapted to the surgery of "White" Cataract.

[Trachomatous entropion trichiasis at the ophthalmologic clinic of Dantec CHU (apropos of 199 cases)]. / L'entropion-trichiasis trachomateux à la clinique ophtalmologique du CHU aristide le dantec (à propos de 199 cas).

In Senegal as well as others developing countries trachoma is a real public health problem. Entropion trichiasis is its most common and its most blinding complication. The authors made a retrospective study on 137 records of patients who underwent 199 surgical cures on a two years period. Epidemiologically, the average age is 49 years with a significative higher percentage of woman. Clinically, 51.5% of the patients had already complications, mostly on the cornea. The Trabut technique was the most used and its results was good in 82.4% cases. The authors underlined the duality of entropion trichiasis characterized by the ocular morbidity linked to the corneal damages and the simplicity of the surgical treatment which present definite advantages. Meanwhile they remind that the best treatment of the entropion trichiasis remains the prophylaxy of trachoma.
