Different techniques of extracapsular cataract extraction: bacterial contamination during surgery. Prospective study on 230 consecutive patients.

This study was performed to investigate the correlation between the contamination of the anterior chamber and the technique of extracapsular cataract extraction (ECCE). Three different methods were used: uncomplicated planned ECCE, phacoemulsification involving suturing method, and sutureless technique. All patients had posterior chamber intraocular lenses implanted.

Canaliculitis: difficulties in diagnosis, differential diagnosis and comparison between conservative and surgical treatment.

The most important clinical features of canaliculitis include a red, swollen eyelid in the area of the affected canaliculus, a unilateral conjunctivitis, a mucopurulent discharge and in some cases dacryoliths visible in the lacrimal punctum. Conservative therapy was found to be little effective: only 10% of the patients could be cured, 40% showed a recurrence after conservative treatment. 20 patients (50%) were treated by canaliculotomy: 16 of these were cured by this surgical treatment, 4 patients complained of epiphora, although diagnostic syringing showed free lacrimal pathways.

Gore-Tex soft-tissue patch frontalis suspension technique in congenital ptosis and in blepharophimosis-ptosis syndrome.

The frontalis suspension technique is the surgical method of choice in ptosis patients with a levator function of 2 mm or less. This type of ptosis is found unilaterally or bilaterally in isolated congenital ptosis and mostly bilaterally in blepharophimosis-ptosis patients. The frontalis suspension technique is frequently used in children being operated on because of congenital ptosis, where the excision of the fasciae latae can be avoided so as not to risk scarring the donor area.

[Morphology of the anterior vitreous body membrane in congenital aniridia].

Background: Hitherto no attention was paid to the prebasal vitreous body in children with congenital aniridia. Obviously there are, at least occasionally, two remarkable anomalies of the anterior hyaloid membrane.

Materials And Methods: Two children (one 3 years and the other 4 years old) with congenital anirida were examined in supine position at a special slitlamp in general anaesthesia.

Macrophages incorporate PTFE-material of explanted polytetrafluoroethylene lacrimal prosthesis.

In a 29 year old patient suffering from complete posttraumatic obstruction of the lacrimal system a PTFE-vascular graft was implanted as a bypass between conjunctival and nasal mucosa. The bypass was patent and well tolerated for 2 1/2 years before it had to be removed because of a therapy refractive naso-cutaneous fistula. Light- and electronmicroscopy of the explanted material showed an accumulation of inflammatory cells and fibrovascular tissue growing into the internodal spaces from both the outer and luminal surface.
