We report a further four cases of spontaneously resolved primary congenital glaucoma, including one case seen both prior and subsequent to the resolution. This condition is detected usually in eyes with megalocornea, which are later found to have breaks in Descemets membrane. Two other patients also had this diagnosis made, but later developed active glaucoma, requiring surgical treatment, indicating the need for continued observation of apparently abortive forms of congenital glaucoma.
Ciliary-block glaucoma occurred in one eye of a 65-year-old-male, following a combined trabeculectomy and extracapsular lens extraction for long-standing angle-closure glaucoma. After pupillary block was excluded as a cause, a posterior capsulotomy resolved the condition. This procedure was repeated successfully when a flat anterior chamber recurred on spontaneous closure of the initial capsulotomy. The ciliary block appeared to be caused by the residual zonule and lens capsule.
A retrospective analysis of 80 cases of gonococcal ophthalmia revealed six (7.5%) to be due to penicillinase-producing Neisseria gonorrhoeae (PPNG), five neonatal cases and one adult. All six cases were finally cured, but best results were obtained with topical chloramphenicol and single-dose spectinomycin (40 mg/kg) given intramuscularly. All gonococcal isolates should be tested promptly for penicillinase production, and if this is present systemic treatment, modified to spectinomycin or penicillinase-stable cephalosporin, should be given as single-dose treatment.
A case of acute orbital myositis is presented in this report. CT scanning provided an immediate diagnosis and hence institution of treatment. There was a typically rapid response to steroids. A previous presentation, prior to the advent of CT, had been misdiagnosed as Tolosa-Hunt syndrome. Orbital pseudotumour can be acute or chronic, and acute orbital myositis is now regarded as one of five subtypes of the former.
