The eye and the hand: a clinical review.

The visual system is highly susceptible to involvement in many systemic disorders. Disorders of tissues common to the eye and the hand, such as vascular, connective and neural, may have striking clinical signs in both. Thus signs in the hand may provide useful diagnostic clues in the assessment of disorders of the visual system. The hand may even be causative in traumatic or infective eye diseases. This review provides a schema for a suitable hand examination and documents the eye and hand features of various common and uncommon disorders. The importance to the ophthalmologist of a careful hand examination is emphasised.

Kimura's disease of the orbit.

A 70-year-old man presented with proptosis and ptosis of the right eye. An orbital mass was palpable and computed tomography scanning and magnetic resonance imaging scanning confirmed its superior orbital position, with extension back to the orbital apex. Definitive biopsy, undertaken via an anterior orbitotomy, demonstrated the lesion to be Kimura's disease. The patient was managed conservatively, and most of his symptoms resolved. Kimura's disease involving the orbit is briefly reviewed in this paper.

Light microscopic and electron microscopic histopathology of an iris microhaemangioma.

A patient who had been observed to have an iris microhaemangioma (capillary haemangioma), confirmed on fluorescein iris angiography, came to cataract surgery. The lesion was excised at the time of surgery and submitted to light and electron microscopic study. It had the features of a hamartoma of the capillary haemangioma type, with its characteristics being specific for vessels seen in iris tissue.

Laser trabeculoplasty and its effect on tonography, central visual fields, and anterior chamber depth. A preliminary study.

A preliminary study of ten patients with glaucoma, each of whom has undergone laser trabeculoplasty to one or both eyes, is presented. Tonography-on-treatment was performed on each patient approximately four weeks prior to laser, and repeated approximately ten weeks afterwards. Central fields and anterior chamber depth measurements before and after laser trabeculoplasty are also presented. Intraocular pressures fell by a mean of 12.34 mm (SD +/- 8.5, range 3-23) in all 12 lasered eyes. Central fields improved in ten eyes, and the anterior chamber of treated eyes became shallower by an average of 0.27 mm, compared with untreated eyes (p less than 0.05). Po/C values improved in 11 treated eyes. Very little attempt was made to alter medical treatment during the period outlined above.

An evaluation of signs in ocular myasthenia gravis and correlation with acetylcholine receptor antibodies.

Fifteen patients with ocular myasthenia gravis were examined in detail for 21 different signs, and tested for acetylcholine receptor antibodies. The major signs of ocular myasthenia gravis included ptosis, disorders of ocular rotations, weakness of eyelid closure, "pseudosupranuclear" signs and the lid twitch sign. Acetylcholine receptor antibodies were found in eight of the 15 patients. One hundred and four normal, non-myasthenic patients were also examined for the lid twitch response, and the relationship between the lid twitch of ocular myasthenia gravis and that found in normal subjects is discussed.

A ten-year hospital survey of eyelid cancer.

Two hundred and four cases of malignant eyelid tumours, managed at the Concord Hospital, were reviewed. These cases spanned a ten-year period between 1973 and 1982 and all were treated surgically. The nature of each tumour was confirmed by histopathological examination. Included in this review were the site of the tumour, the tumour pathology, the surgical management, the type of surgeon involved, the ocular complications, the management of recurrences and any mortality. The importance of preventing recurrences by adequate initial surgery with frozen section control is emphasized.

The disposable modified fornix flap for cataract surgery.

Thirty cataract operations were performed in 28 patients using the disposable modified fornix flap technique described by Quinn and Ewald. Vision was 6/12 or better in 26 of 30 eyes with a mean follow-up period of seven months. Vision was corrected in 11 patients with intraocular lens implants, in 10 patients with aphakic spectacles and in seven patients with contact lenses. Four of the seven contact lens wearers had ocular irritation related to contact lens wear. The technique appears to work satisfactorily for intracapsular or extracapsular cataract surgery and for intraocular lens implantation.

Bilateral eye injuries from motor vehicle trauma.

Three patients admitted after motor vehicle accident trauma are presented. Each had bilateral eye injuries with significant but variable visual loss. Common features to each were alcohol intoxication and lack of use of seatbelts, and each was young and male. New microsurgical ophthalmological techniques as well as a multidisciplinary surgical approach to these types of injuries are emphasized.

Adult penicillinase-producing gonococcal keratoconjunctivitis.

The case is described of a 22-year-old man who presented with ulcerative keratitis as a complication of conjunctivitis that was caused by penicillinase-producing Neisseria gonorrhoeae. The need for first-line treatment with antibiotic agents that are resistant to beta-lactamase breakdown is discussed.

Recurrent acute myelomonoblastic leukaemia presenting as a red eye.

A 68-year-old man was first diagnosed as having acute myelomonoblastic leukaemia on March 17, 1983. After two remissions with treatment, he suffered a further relapse, which caused him to present with a red eye, visual failure, and oedema of the right optic nerve head. Examination of cerebrospinal fluid that was obtained on lumbar puncture demonstrated an acute central nervous system relapse. Computed tomographic scanning led to the diagnosis of leukaemic infiltration of the optic nerve. Systemic and intrathecal treatment by appropriate chemotherapy and by orbital radiotherapy led to resolution of the clinical problem.
