Alcaligenes xylosoxidans endophthalmitis 8 months after cataract extraction.

PURPOSE: To report a case of Alcaligenes xylosoxidans endophthalmitis and to increase awareness of its potential as an intraocular pathogen. METHODS: An 80-year-old woman in good general health developed A. xylosoxidans endophthalmitis 8 months after an uncomplicated cataract extraction performed at another institution. Eventually, vitrectomy with removal of the intraocular lens and capsule was performed because of recurrent disease after intravitreal antibiotic injections. RESULTS: Microbiologic examination of the vitreous biopsies and capsule disclosed A. xylosoxidans, a motile, gram-negative rod resistant to many antibiotics. CONCLUSION: A. xylosoxidans should be considered as a cause of low-grade endophthalmitis after cataract surgery.

Analgesic effects of sub-Tenon's versus retrobulbar anesthesia in planned extracapsular cataract extraction.

BACKGROUND: A prospective study was conducted to compare the analgesic effects of sub-Tenon's and retrobulbar anesthesia by assessing patients' response to the visceral stimulus. METHODS: Seven hundred and twenty eyes of 720 patients underwent extracapsular cataract extraction and posterior chamber intraocular lens implantation. They received retrobulbar anesthesia with 3 ml lidocaine (225 eyes), retrobulbar anesthesia with 5 ml lidocaine (216 eyes), or sub-Tenon's anesthesia with 3 ml lidocaine (279 eyes). Pain scores were recorded when an acetylcholine chloride solution was injected into the anterior chamber to attain miosis after lens implantation. RESULTS: Pain scores were significantly different among the three anesthesia groups (P<0.0001, Kruskal-Wallis test). The multiple comparison revealed that analgesic effects were highest with sub-Tenon's anesthesia, followed by 5-ml retrobulbar and 3-ml retrobulbar anesthesia. CONCLUSION: Sub-Tenon's anesthesia is an effective and reliable anesthetic method in cataract surgery.

Distant arterial thromboembolization as a postoperative complication of cataract extractions.

This paper describes and analyzes an almost-unreported postoperative complication. Arterial thromboemboli are a concern with hospital populations, where their relative incidence is higher than in the general population. Four case reports are mentioned: Each patient underwent a cataract extraction and, following time periods varying from one day to two months, sustained a thrombosis of a main leg artery. Possible etiologies are discussed. All patients had an impaired immune status in some way, and either this or the resultant steroid treatment may be implicated in their postoperative complication. All patients had cardiovascular histories, and two had previous duodenal ulcers.

Lens capsule inclusion in trabeculectomy with cataract extraction.

PURPOSE: To deliberately include a flap of anterior lens capsule in the trabeculectomy site to determine whether it aids filtration in a glaucoma bleb. SETTING: El-Maghraby Eye Hospital, Jeddah, Saudi Arabia. METHODS: The study comprised 23 consecutive patients (25 eyes) with dense cataract and uncontrolled glaucoma despite maximum medical therapy. Combined trabeculectomy, planned extracapsular cataract extraction, posterior chamber intraocular lens implantation, and inclusion of the anterior lens capsule under the trabeculectomy scleral flap were performed. Follow-up ranged from 6 to 72 months. RESULTS: All eyes had improved visual acuity mainly because of cataract removal. Best spectacle-corrected visual acuity in 20 eyes ranged from 20/40 to 20/20. A diffuse filtration bleb was achieved in most cases. Postoperative intraocular pressure (IOP) was 20 mm Hg or less in 80% of eyes. Five eyes required additional topical timolol therapy. None required additional carbonic anhydrase inhibitor therapy. CONCLUSION: The combined procedure appeared to be a sound method of providing visual rehabilitation and adequate IOP control. The use of the capsular wick seemed to help maintain glaucoma filtration.

Pupil size after extracapsular cataract extraction and posterior chamber lens implantation: a prospective randomized trial of epinephrine and acetylcholine.

The effects of using epinephrine in the irrigating fluid and intracameral acetylcholine were studied by measuring changes in pupil size in the 48 hours following extracapsular cataract extraction and intraocular lens implantation in 39 eyes. Epinephrine reduced peroperative pupil constriction, but its effect was insignificant thereafter. The pupil constriction following acetylcholine was maximal at 2 hours and was still significant at 4 hours, but pupils redilated by 6 hours. Neither drug had any effect after this time. The edge of most lens implants was visible at 6 hours, after which pupils steadily constricted.

Long-term results of extracapsular cataract extraction with posterior chamber lens implantation: sodium hyaluronate 1% vs hydroxypropyl methylcellulose 2%.

We investigated the frequency of surgical complications and the long-term outcome in terms of visual acuity, intraocular pressure and post-operative complications in 206 extracapsular cataract extraction procedures with posterior chamber lens implantation using either sodium hyaluronate 1% (Healon) or hydroxypropyl-methylcellulose 2% over a follow-up period of 12 months. We found no significant difference in the results of using either of the two viscoelastic agents.

[Risk factors for the vis a tergo of the "open eye" in cataract extraction with local anesthesia].

In a prospective study, 244 patients who were scheduled to undergo extracapsular cataract extraction with implantation of the intraocular lens (ECCE/IOL) under local anesthesia were examined to evaluate the risk factors for vis a tergo (VAT) at the "open eye". The intraoperative blood pressure was found to be the most important factor for the occurence of VAT. We think that a reversible suprachoroidal effusion syndrome is responsible for this effect. In order to minimize intraoperative complications, we recommend routine monitoring and treatment if the intraoperative blood pressure is too high during cataract surgery with local anesthesia.

Abiotrophia species as a cause of endophthalmitis following cataract extraction.

Microorganisms of the genus Abiotrophia, members of the oral flora, are known as important causes of bacterial endocarditis. In this study, we report two individual cases of acute vitreous infection caused by Abiotrophia adiacens and Abiotrophia defectiva approximately a week after cataract extraction. Abiotrophia isolates were recovered by cultivation of vitreous humor on chocolate agar and identified via conventional and API 20 Strep identification systems. An 83-year-old male patient (A) and an 80-year-old female patient (B) demonstrated almost identical symptoms of infectious endophthalmitis manifested as hypopyon and opaque media. The vision of both patients was reduced to detection of hand motion in the left and the right eyes, respectively. An emergency pars plana core vitrectomy was performed, and intraocular antibiotics were administered to each patient, who presented 8 months apart in two different institutions. Patients A and B were treated with an intravitreal injection of vancomycin-amikacin and vancomycin-ceftazidime, respectively, which resulted in complete recovery.

Sodium hyaluronate and methylcellulose in extracapsular cataract extraction. A controlled study of the intraocular inflammation following the peroperative use of sodium hyaluronate and methylcellulose.

In a controlled prospective trial the peroperative use of sodium hyaluronate and methylcellulose (2%) was compared. Two hundred and fifteen patients received sodium hyaluronate and 189 methylcellulose during extracapsular cataract extraction. We found no significant difference in postoperative anterior chamber inflammation, intraocular pressure, frequency of fibrin in the anterior chamber, nor need for additional medication during the first 5 postoperative days.

Creating cataracts of varying hardness to practice extracapsular cataract extraction and phacoemulsification(2).

We describe a method to harden the nucleus of crystalline lenses in postmortem human globes by intralenticular injection of a mixture of paraformaldehyde and glutaraldehyde (Karnovsky's solution). Evaluation of the nuclear manipulations, using the Miyake-Apple posterior video/photographic technique, shows that the method provides suitable specimens for practicing extracapsular cataract extraction and phacoemulsification.
