Retinal detachment after cataract extraction in myopic eyes

PURPOSE

To determine the incidence of retinal detachment (RD) after cataract extraction in people 40 years of age or older with axial myopia (i.e., axial length > or = 25.5 mm).

SETTING

Fifteen Danish eye clinics.

METHODS

Two hundred forty-five eyes had cataract extraction performed at 15 eye clinics; 237 eyes had extracapsular cataract extraction (ECCE) and 8 eyes, intracapsular cataract extraction (ICCE). Postoperative data were reported by the practicing ophthalmologists. Mean follow-up was 27 months (range 14 to 32 months).

RESULTS

Five RDs occurred in the 245 eyes (2.0%). Excluding the ICCE cases and the two cases of combined cornea transplantation and ECCE, RD occurred in 4 of the 235 eyes that had ECCE (1.7%). The incidence after ECCE with posterior chamber lens implantation was 1.4%. Complete postoperative status was reported on 158 eyes. Forty-eight eyes (30.4%) had a neodymium:YAG capsulotomy and 3 (6.0%) developed an RD 1, 3.5, and 21 months after the capsulotomy.

CONCLUSION

The RD incidence after ECCE with posterior chamber lens implantation was low but higher than that in unselected populations. The incidence increased after laser capsulotomy.

[Risk of cataract surgery in patients with myopia. A prospective Danish multicenter study with special reference to a complication]

A prospective Danish multicentre study was conducted to evaluate the incidence of retinal detachment after cataract extraction in myopic eyes (axial length, > or = 25.5 mm). Two hundred and forty-seven cataract extractions in myopic eyes were reported during a period of 13 months. Two hundred and forty-one eyes underwent extracapsular and six eyes intracapsular cataract extraction. The mean follow-up time for 158 eyes was seven months (ranging from 1-30 months). In five cases a retinal detachment was observed, one case was probably present preoperatively, this person had undergone intracapsular cataract extraction. The incidence of retinal detachment was thus 1.62-2.02% in the total material and 1.66% in eyes operated with extracapsular cataract extraction.

Fluconazole in the management of fungal ocular infections

The number of fungal infections has increased dramatically, and those involving the eye pose a serious problem and treatment challenge to practicing physicians. Despite the overall effectiveness of conventional treatment with amphotericin B, there are several well-recognized disadvantages associated with this drug. The topical agent natamycin, although effective against the filamentous fungi, is less effective against Candida species. Ketoconazole, an effective broad-spectrum, oral antifungal, possesses a better safety profile than amphotericin B, but is also associated with potential toxicity and drug interactions. The ongoing search for improved antifungal compounds led to the development of fluconazole. This review article focuses on fluconazole in the treatment of patients with fungal infections of the eye. In addition to its proven effectiveness and safety in patients with various mycoses, the pharmacokinetic profile of fluconazole confers many advantages including diffusion into ocular tissue. A number of reported cases document the effectiveness of this triazole in human ocularmycoses without the occurrence of significant side effects.

Fluconazole in the treatment of candida albicans endophthalmitis

A 29-year-old former drug addict with candida albicans endophthalmitis determined by cultivation was treated with vitrectomy and systemic fluconazole. The infection resolved completely and the patient recovered a visual acuity of 6/6. Fluconazole was well tolerated and a high concentration was found in the vitreous cavity.

Intraocular pressure in the first days after implantation of posterior chamber lenses with the use of sodium hyaluronate (Healon)

Intraocular pressure (IOP) was measured before and 6, 24, 48 and 72 h after extracapsular cataract extraction with implantation of a posterior chambers lens in 3 groups of patients. Group I (30 patients): Sodium hyaluronate (Healon) was used during anterior capsulotomy and lens implantation and was aspirated at the end of surgery. Group II (22 patients): Healon as in group I + 500 mg acetazolamide at the end of surgery. Group III (17 patients): BSS and/or air was used instead of Healon during surgery. In all groups statistically significant rises in IOP after 6 h were followed by significant falls in the remaining post-operative period. The rise and subsequent fall in IOP was significantly greater in group I than in group III. Acetazolamide in group II did not prevent excessive rises in IOP. Aspiration probably shortens the period of Healon-induced hypertension. We recommend a meticulous aspiration of Healon at the end of surgery.
