1/11. The use of contact B mode ultrasound in pediatric ophthalmology.

    It has been shown that an ultrasound system such as the Bronson-Turner Contact B Mode can be added, fruitfully, to the armamentarium of the individual pediatric ophthalmologist. It can be used quickly and precisely with an ophthalmological training and without patient discomfort or anesthesia no matter what the age. Valuable anterior segment information can be readily gained without a waterbath. Examples are shown of children with opaque media who were found to have congenital cataracts and congenital aphakia, microphthalmos, PHPV, retinal anomalies and ectatic coloboma.

2/11. Cataract surgery for natural rubber latex allergic patients.

    The prevalence of reactions against natural rubber latex (NRL) is thought to be increasing in both the general public and healthcare workers. These can vary from mild benign skin reactions to bronchospasm, anaphylactic shock, and death. Difficulties exist for ophthalmic departments wishing to establish protocols in providing 'latex-free environments' for patients undergoing cataract surgery. Currently no legislation exists regarding the labelling of NRL-containing products in the United Kingdom with information on a product's NRL content provided by the manufacturer on a voluntary basis only. It is hoped this review article will act as a basic guide in the management of NRL-sensitive patients undergoing cataract surgery in the United Kingdom.

3/11. Pathogenesis of posterior capsular opacification. Part II: Histopathological and in vitro culture findings.

    The most interesting sources of information about the pathogenesis of posterior capsular opacification seem to be histopathological studies and in vitro tissue cultures. Since our surgical technique is extracapsular cataract extraction, the explants we used for tissue culture consisted of the anterior capsule epithelial sheet without the equatorial germinative zone. We successfully overcame several problems by using the autologous plasma clot culture method. This medium, considered the optimal one for this type of culture, allowed us to study the heterogeneous behavior of the epithelial cells in culture. Using the plasma clot culture method, we were able to demonstrate in vitro fibroblastic transformation of the epithelial cells. Histopathological findings of particular cases of posterior capsule opacification and immunohistochemistry of the human lens are also reported.

4/11. seasonal affective disorder and visual impairment: two case studies.

    Winter depressive episodes in patients with seasonal affective disorder are induced by light deficiency and are successfully treated by enhancing environmental light. The authors investigated the role of abnormal visual information processing in the genesis of seasonal affective disorder symptoms by examining two patients with impaired vision and recurrent winter depressions. The first patient developed winter depressions after developing a traumatic cataract in one eye, and was helped by light therapy. The second patient, fully blind since she was 1 year old, nonetheless suffered as an adult from winter depressions, which responded to bright--but not to dim--light treatment. The authors discuss the implications of these findings.

5/11. Preferential looking as a guide for amblyopia therapy in monocular infantile cataracts.

    Despite recent advances in surgical technique and refractive correction, amblyopia remains a significant problem in the treatment of monocular infantile cataracts. amblyopia therapy recommended by different authors during the preverbal period has varied from no patching to nearly full-time occlusion of the phakic eye. We measured preferential looking (PL) acuities sequentially in four infants following monocular cataract surgery and contact lens correction. This information was used to adjust occlusion of the phakic eye, which was prescribed 25%-100% of waking hours. Patching schedules were altered, on average, every three to four months in response to changes in PL acuities. Four increases in patching intensity retarded acuity development in the phakic and benefited development in the aphakic eyes. Nine decreases enhanced progress or yielded no change in the phakic and, with two exceptions, impeded progress in the aphakic eyes. Recognition acuities now available for two of the children show continuity with previous PL acuities and confirm useful vision in the aphakic eyes. We describe guidelines for adjusting occlusion based on our experience. We believe that PL modulation of patching therapy may result in more favorable visual outcomes for both eyes of infants with monocular cataracts.

6/11. Hereditary bone dysplasia with malignant change. Report of three families.

    In this paper three families are reported with members who had hereditary bone dysplasia that was originally described by Arnold in one family. We provide further information about that family and suggest that the diagnosis of the malignant change should be changed from fibrosarcoma to malignant fibrous histiocytoma. A thorough search of the literature has failed to reveal any conditions, either hereditary or acquired, that are similar. The major feature of the dysplasia is diaphyseal medullary stenosis of bone with overlying cortical-bone thickening, and the propensity to malignant transformation and fractures with minimum trauma is emphasized. The tumors in seven, and possibly eight, of the nine patients in whom a malignant lesion developed were originally classified as fibrosarcoma and proved to be markedly aggressive. The hereditary pattern appears to be autosomal dominant. The clinical manifestations of a malignant lesion occur generally in the second to the fifth decades of life.

7/11. Biofeedback treatment of strabismus: case studies.

    This project demonstrates the use of neuromuscular reeducation biofeedback as a treatment for strabismus. Of the three subjects treated, an exotrope and an esotrope were cured according to pre-defined criteria and an exotrope with a dense monocular cataract was improved. Treatment consisted of monitoring eye positions using infrared sensors and feeding back information on relative ocular deviations coded in the form of a tone.

8/11. acanthamoeba keratitis: a sobering case and a promising new treatment.

    This case report describing acanthamoeba keratitis in a 41-year-old male disposable contact lens wearer, adds some sobering and some encouraging information for the future management of this infection. Initial treatment with topical propamidine isethionate (Brolene) and polymyxin b/neomycin/gramicidin (Neosporin) led to an unsatisfactory clinical response. Topical miconazole 1%, prednisolone acetate 0.12% and oral itraconazole were then added to his treatment. This was later discontinued on noticing ipsilateral toxic cataract formation and an unresponsive pupil. The above medications were replaced with topical polyhexamethylene biguanide (PHMB) 0.02%, which we had shown to have superior in-vitro amoebicidal activity when compared to the other antiamoebic agents used in this case. Withdrawal of the multitreatment schedule and commencement of PHMB was associated with resolution of his keratitis, healing of a large epithelial defect and settling of severe conjunctivitis. The identical Acanthamoeba strain was isolated from the patient's contact lens storage case and cornea, possibly implicating the contaminated contact lens case in the aetiology of his keratitis. This is the first Australasian experience using PHMB to treat acanthamoeba keratitis. It appears to be a promising new treatment for this infection.

9/11. Autosomal dominant inheritance of iridogoniodysgenesis and cataract.

    BACKGROUND: There has been only one report in the literature of iridogoniodysgenesis associated with cataracts in two brothers. In that report, the authors conclude that the condition was inherited by autosomal recessive transmission. methods: The authors evaluated 10 members in three generations of a family in which there is a striking prevalence of pre-senile hypermature cataract formation and iridogoniodysgenesis. In addition, historical information regarding two deceased members of the family was studied. RESULTS: Six of 10 family members evaluated have iridogoniodysgenesis. Four of five siblings have had pre-senile hypermature cataracts. Despite the iridogoniodysgenesis, there appears to be no association with glaucoma in any of these patients. CONCLUSION: The inheritance pattern of this syndrome appears to be that of autosomal dominance with variable penetrance. The authors believe that this report helps to clarify the inheritance pattern of this previously described hereditary syndrome.

10/11. Simultaneous surgery for bilateral pediatric cataracts.

    BACKGROUND AND OBJECTIVES: To perform a review of the literature comparing the safety of bilateral simultaneous lensectomies in children versus the risk of more than one general anesthesia within a short time frame, and to study the results of bilateral surgery in a small group of patients. patients AND methods: Bilateral simultaneous lensectomies were performed in 9 children (18 eyes), in whom increased anesthetic risks warranted this approach. RESULTS: There were no postoperative complications for at least 6 months. CONCLUSION: Data in the current literature on endophthalmitis after cataract surgery and on the risks of repetitive anesthesia are inadequate to weigh the risk of bilateral endophthalmitis against the reduced risk of one anesthesia versus two and the advantages of simultaneous early visual rehabilitation. Until such information becomes available, simultaneous removal of bilateral infantile cataracts should probably be reserved for selected cases where the anesthetic risk is higher than average.
