A decade of ophthalmic statistics in Papua New Guinea.
This review is a composite of quarterly reports from an ophthalmologist's clinic in Madang over a ten-year period. The aim was to encompass ophthalmological practice in this situation quantitatively and qualitatively. It reflects, in the author's opinion, the state of ophthalmological services at present offered including ancillary services, and comments are made on some of the pathology encountered and surgery performed.
An ocular survey of community school children in Madang Province.
An ocular survey was done on 6,153 children in 30 community schools in the Madang Province of Papua New Guinea over a two year period. Trachoma was diagnosed in 19.6% of subjects but was mild and asymptomatic in most. 9.6% of trachoma patients had moderate to severe disease, but only 5.3% required treatment. A significant refractive error was noted in 1.4% of subjects, and colour perception deficiency was found in 4.7% of boys and 0.5% of girls. 1.2% of subjects had other ocular abnormalities most of which were minor. Training paramedical workers and students in screening methods for ocular disease is one of the most important aspects of ocular surveys as many will be posted to remote areas of provinces which cannot be visited by an ophthalmologist or ocular survey teams.

Primary eye malignancy in Papua New Guinea.
Primary eye malignancy presenting in Papua New Guinea over a twelve-year period is surveyed. Subsequent cases presenting at Angau Memorial Hospital, Lae, are mentioned. Primary malignancies of the eye and orbit in general are discussed with particular emphasis on retinoblastoma.
Unilateral proptosis.
A series of 22 cases of unilateral proptosis at Angau Hospital, Lae, presenting over a 22-month period are analysed. The cases are discussed individually with emphasis on aetiology, treatment and prognosis. The differential diagnosis of unilateral proptosis is outlined.

Giant millipede 'burns' and the eye.
A retrospective review of 8 cases of millipede 'burns' (caused by Polyconoceras sp. [= Salpidobolus sp.]) of the eye and periorbital tissues seen in a specialist ophthalmology unit over 6 years at Madang General Hospital, Papua New Guinea, was conducted. Such cases comprised 0.06% of the 14,000 patients seen in the same period. All cases were seen in the rainy season. Apart from one adult, all cases were children (age range 9 months-7 years). Clinical manifestations included a 'burn' of periorbital skin (all 8 cases), marked periorbital oedema (3 cases), conjunctivitis (2 cases), and keratitis (one case). All patients recovered fully with standard topical ophthalmic therapy. Despite anecdotal reports that blindness is a likely sequela of millipede 'burns' of the eye, it did not occur in this, the only published series of the condition.
