A case of unilateral Salzmann's nodular degeneration of the cornea is reported. The elevated corneal nodules were accompanied by a prominent Hudson‐like, iron line.
A 32 year old black male consulted the Optometry Clinic, Q.1 .T., because he required prescription sunglasses. His iow myopic prescription did not require changing and gave visual acuities of R 6/5, L 615. External eyes, intra-ocular pressure and binocular functions were ail normal.Ophthalmoscopy revealed a slightly raised, heavily pigmented melanocytoma on the inferior-temporal aspect of the left optic disc, (photograph). The superior border of the lesion appeared fibrillated. There was no afferent pupillary defect or nerve fibre bundle field loss.A melanocytoma is a form of weal naevus and is usually seen on or next to the optic disc. Typically, they are unilateral and discovered routinely. An enlarged blind spot or nerve fibre bundle defect may be seen on examining the visual field, and some patients also show an afferent pupillary defect. Vision is usually normal. A small increase in size may occur over a long period of time, but the tumour is characteristically benign and stationary. Differential diagnosis includes hyperplasia of the peripapillary retinal pigment epithelium, juxta-papillary retinal pigment epithelial hamartoma and malignant melanoma. Its higher frequency of occurence in dark skinned people and fibrillated border are helpful in distinguishing melanocytoma and malignant melanoma. Malignant change is rare and patients should be followed by serial photography at regular intervals. Reference 1. Reidy. J. J., Apple, D. J., Steinmetz, el 01.

A method of photographing anomalies of the ocular refracting media is described using the Canon CR-45NM non mydriatic camera. The technique is adequate to obtain a good photograph when the normal technique using mydriasis is contra-indicated.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
