Two patients had bilateral, simultaneous Mooren's ulcers that progressed to almost total loss of the corneal stroma in all eyes. The conjunctival epithelium eventually healed over these thinned corneas and the eyes were free of pain and inflammation. Three of the four eyes had combined 7.5-mm penetrating corneal transplants and cataract extractions performed at least four months after disease activity had subsided. All transplants have remained transparent from one to three years postoperatively and there has been no evidence of recurrence of Mooren's ulcers.

Fifty patients in a double-blind study received in randomized fashion either etidocaine HCl (Duranest) 1% or lidocaine HCl (Xylocaine) 2% with epinephrine 1:200,000 in a retrobulbar block for cataract surgery. Two parallel groups of 25 patients each were studied comparing the clinical properties of the drugs. The onset time for sensory and motor blocks of both drugs was essentially the same (3 minutes). The duration of action of etidocaine was considerably longer than lidocaine and less postoperative pain medication was required by patients blocked with etidocaine.

A 71-year-old patient developed acute pupillary block glaucoma two years after uncomplicated extracapsular cataract surgery with primary implantation of a Choyce-style anterior chamber lens. He presented one week after the onset of pain. The attack was relieved with argon laser iridectomy. The presumed mechanism was rotation of the intraocular lens due to blunt trauma, occluding the previously patient single surgical iridectomy site. We felt that in this case, laser iridectomy was a good, safe alternative to surgical iridectomy.

We studied 13 patients, six males and seven females, ranging in age from 14 to 53 years, with chronic pars planitis and a form of secondary retinal degeneration. All had experienced visual blurring but none had significant pain. Nine of the 13 had some disturbance in night vision. Visual acuity had decreased in three patients (in one because of cataract, in one because of cystoid macular degeneration, and for unknown reasons in the third), increased in two patients (because of improvement in cystoid macular edema), and remained stable in eight. There were electrophysiologic abnormalities, consisting of delayed B-wave implicit time, abnormal response to 30-Hz flicker, and reduced B-wave oscillations, in almost every patient. Our finding suggested that pars planitis is a vitreoretinal disorder rather than an inflammatory disease of the uveal tract.

Cataract extraction and iris clip lens implantation in an 88-year-old woman were followed by hyphaema, anterior uveitis and organised exudates around the implant. The globe was enucleated after 15 months due to pain and a poor visual prognosis. Sections showed an epithelial downgrowth into part of the anterior chamber, associated with a fibrous membrane which had surrounded part of one loop of the implant. Atrophy of the iris, adenomatous changes in a ciliary process and an after-cataractous ring were noted. Inflammatory changes were present in the uvea, associated posteriorly with degenerative choroido-retinitis, probably of arteriosclerotic origin. The nylon loops of the implant showed areas of biodegradation and were partly fibrosed in. The possible relationship of the various changes is discussed.

Corneal subepithelial opacification associated with pain, photophobia, and injection has been reported in the first to third day following photorefractive keratectomy (PRK). Regardless of treatment, the resolution has generally left the patient with permanent corneal scarring and a one to two line reduction in visual acuity. We surveyed 50 PRK surgeons and received responses from 17 on 30 cases of this complication, which occurs in approximately one in 300 cases. The etiology is unknown. Cases were first reported when nonsteroidal anti-inflammatory drugs, with or without occlusive contact lens, were substituted for conventional bandage occlusion in the postoperative protocol for PRK.

Fourteen eyes in eleven patients treated by the traditional methods for cataract were evaluated. Three different methods of treatment were classified from the cases: intracapsular (the traditional couching), extracapsular, and zonulysis. The operations were carried out on the left eye in 64%, bilateral in 27%, and right in 9%. Complications noted were uveitis, glaucoma, lens in pupil, posterior capsule opacification, cystoid macular oedema (CMO) but infection was conspicuously absent. Some of the results were good. With those that did not appear acceptable and could be further improved patients either received partial management or did not bother. Pain was the worrying symptom. These results of the traditional methods are not desirable but until intra-ocular lens implantation is widely practised in Ghana traditional methods are likely to compete with orthodox methods to a variable degree.

A combined technique of topical anesthesia (TA) and subconjunctival anesthesia (SCA) was used in 73 consecutive patients undergoing scleral tunnel phacoemulsification cataract surgery. Medical records were evaluated preoperatively, intraoperative, and postoperatively. A patient questionnaire was used to obtain subjective intraoperative and postoperative information. Preoperative and intraoperative sedation of varying degrees was necessary. Ninety-five percent of the patients reported no pain. No patients required additional retrobulbar or peribulbar anesthesia. The most frequent postoperative problems were pain, a need for patching, and headache. The combined TA and SCA technique appeared safe, medically acceptable, and cost-effective.

Fuchs' heterochromic iridocyclitis is an unusual form of uveitis of unknown aetiology that continues to be poorly understood and underdiagnosed. We present the clinical features observed in 77 patients (89 eyes) seen in the Uveitis Clinic at Leicester Royal Infirmary over a 2-year period. The most common presenting symptom was visual deterioration (96.1%) rather than pain (18.2%). Only 50.6% were diagnosed as Fuchs' heterochromic iridocyclitis at presentation. At review, clinical heterochromic iridum was observed in 70.1% and 15.6% were bilateral. Lens opacities were seen in 73.0%, 40.4% (of the total) having undergone cataract surgery. Glaucoma was diagnosed in 15.7% at presentation and in 21.3% at review, by which time 9.0% (of the total) had required filtration surgery. It is important that Fuchs' heterochromic iridocyclitis is diagnosed correctly since, although many patients do not require active treatment, all should be screened at regular intervals for glaucoma.

This article reports the results of using subconjunctival anesthesia (SCA) in cataract surgery. Subjective patient questionnaires and the medical records of 133 consecutive SCA patients who had scleral tunnel phacoemulsification cataract surgery were analyzed. All SCA patients received preoperative medication, but most (77%) received no intraoperative medication. Most patients who had SCA (90%) reported no pain during surgery. The most common postoperative complaints were pain, patching, and headache. Uncorrected visual acuity, tested a mean time of 35 minutes after surgery, was 20/200 or better in 69% of the SCA patients. Subconjunctival anesthesia provided a safe, effective, and minimally invasive technique.
