[Fungal keratitis in an intertropical area: diagnosis and treatment problems. Advantage of local use of polyvidone iodine].

Fungal infection is rarely investigated in keratitis. The authors report five cases of fungal keratitis observed at the le Dantec University Teaching Hospital of Dakar, Senegal, involving two males and three females. Diagnosis was made by examination of smears and cultures of corneal scrapings revealing Candida albicans isolated in four patients and Acremonium strictium in another after 2 or 12 weeks of treatment with antibiotics, antivirals, or steroids. Povidone iodine 2.3% concentrated eye drop was used alone or with an azole for 4 a mean of weeks. All patients presented corneal scars. Fungal keratitis must be considered in presence of torpid corneal ulcer and corneal scraping must be systematically done. Topical povidone iodine alone or associated with azole may be an alternative fungal keratitis treatment in intertropical areas.

[Aniridia: five case studies].

INTRODUCTION: Aniridia, or congenital absence of the iris, is a rare and severe ocular abnormality. We report five cases diagnosed in our department over the last 5 years and describe our clinical findings and attitude. OBSERVATIONS: The patients were two adults and three children, 8-45 years old at the time of diagnosis. Visual acuity ranged from light perception to 20/50. Aniridia was associated with other abnormalities in four cases: lens ectopy in one case, ptosis in three cases, microcornea in one case, macular hypoplasia in three cases and a pterygium coli associated with a pectus excavatum in one case. All patients had complications: corneal dystrophy in three cases, lens opacities in five cases, elevated intraocular pressure (IOP) in two cases, severe amblyopia with nystagmus or strabismus in three cases. Only patients with glaucoma received IOP-lowering medications. IOP was normalized in both cases and regular controls were instituted for all the other patients. DISCUSSION: Management of aniridia is complex in our regions because patients often consult late, at a stage that involves complications and amblyopia. First-intention surgical treatment of glaucoma is not always justified. CONCLUSION: Only genetic counseling, a close follow-up after an early diagnosis and adapted surgical techniques can improve the visual prognosis of aniridia patients.

[Contribution of the Kansas technique for reducing complications of mature cataract surgery].

PURPOSE: We report our experience with the Kansas technique of phakosection which eliminates or limits most complications of classic manual extracapsular extraction. PATIENTS AND METHODS: This retrospective study included our first 80 patients undergoing surgery for mature cataract between May 1996 and May 1998 where we used the Kansas technique. We compared outcome with a group of 30 patients who underwent classic manual extracapsular extraction in a study performed in 1995 by the same surgeon in the same hospital. RESULTS: Per- and post-operative complications were significantly lower with phakosection. Functional rehabilitation was quicker, better and provided better patient comfort. DISCUSSION: Despite some difficulties encountered in a public hospital (viscoelastic excessively fluid and in small quantity, lack of suitable knives or reuse of sterilized disposable knives), we found that the Kansas technique is very well adapted to mature cataracts and our working conditions. CONCLUSION: Phakosection allowed us to give our patients with mature or very mature cataracts the benefit of small incisions. With a moderate increase in cost, this technique significantly reduced our per- and post-operative complication rates and gave quicker and better visual recovery. In our countries, this technique provides better care than phakoemulsification.
