Extracapsular cataract extraction after vitrectomy.

OBJECTIVE: To ascertain the reliability, safety, and effectiveness of extracapsular cataract extraction (without the use of pars plana infusion) in eyes that have had vitrectomy. SETTING: The Manchester Royal Eye Hospital. METHODS: A retrospective analysis of surgical and postsurgical complications and visual acuity change in 41 patients who had one or more vitreoretinal procedures, followed by extracapsular cataract extraction and intraocular lens implantation at a subsequent date. RESULTS: No significant operative complications were encountered using an extracapsular technique without pars plana infusion. Thirty eyes (73.2%) had a significant increase in visual acuity, 10 (24.4%) did not change, and 1 worsened. CONCLUSIONS: A modified form of extracapsular extraction, with control of intraocular fluid flow but without the use of a pars plana infusion, is safe and effective in post-vitrectomy eyes.

The Fasanella-Servat procedure: a retrospective study.

A retrospective study was carried out to assess the success of the Fasanella-Servat procedure for the management of the aponeurotic defect type of adult ptosis. Eighteen procedures were carried out on 16 patients. The mean follow-up was 3 years. The success rate of the operation was 28% with a mean residual tarsal plate height of 5 mm with a very variable tarsal plate contour.

Peribulbar and retrobulbar anesthesia with prilocaine: a comparison of two methods of local ocular anesthesia.

Prilocaine (Citanest) has been shown to be a satisfactory alternative to lignocaine, with certain important advantages, including superior diffusion. The latter may be especially important in peribulbar anesthesia, where the level of diffusion is a critical factor in providing a timely, high-quality block. In a prospective randomized study, we compared the effectiveness of peribulbar vs retrobulbar administration of prilocaine. Eighty-seven patients undergoing elective intraocular surgery were randomized to receive either retrobulbar or peribulbar anesthesia with prilocaine 3% with felypressin and hyaluronidase. Pain of injection, akinesia, and anesthesia were evaluated at predetermined intervals after injection. Except for the fact that lid akinesia occurred earlier in the peribulbar group, there was no difference in the quality or rate of onset of overall akinesia in the two groups. Nor were there any differences in the pain associated with injection. Both groups had excellent operative anesthesia and akinesia.

Acute closed-angle glaucoma and Nd-YAG laser iridotomy.

Forty-one patients presenting consecutively with acute angle closure glaucoma (AACG) were studied with a median follow-up period of eight months. Four patients presented with bilateral symptoms. Thirty-nine patients underwent Nd-YAG laser iridotomy (42 AACG eyes and 36 fellow eyes). Only 15 patients (36.6%) required simply iridotomy; the remainder required additional long term medical or surgical treatment. Longer duration of symptoms and a history of previous intermittent, spontaneously resolved AACG were more common in those requiring additional treatment. Cataract extraction with intraocular lens implantation was performed for three eyes with AACG, and this mode of treatment is discussed as a possible primary treatment. One eye with AACG suffered a second episode, and two fellow eyes developed AACG despite laser iridotomy. Possible mechanisms are discussed. Provocative testing or frequent careful observation of iridotomy patency is recommended.
