The incidence of primary ocular malignant melanoma in blacks during the last 25 years in a large part of the Transvaal Province of South Africa is reported. Only 8 cases were diagnosed, 1 uveal, 4 conjunctival, and 3 orbital. During this same period 153 cases of primary ocular malignant melanoma were diagnosed in whites. The rarity of these tumours among blacks is stressed and the reasons for t...

The rat optic nerve is a useful model for stem cell regeneration research. Direct injection into the rat optic nerve allows delivery into the central nervous system in a minimally-invasive surgery without bone removal. This technique describes an approach to visualization and direct injection of the optic nerve following minor fascial dissection from the orbital ridge, using a conjunctival trac...

Microphthalmos with orbital cyst is a rare congenital abnormality of fetal fissure closure leading to small eyeball associated an cyst. In this case series, we describe six such cases and discuss the clinical features, differential diagnosis, diagnostic modalities, management in accordance existing literature. Out cases, four were male two females. All presented swelling lower eyelid involved e...

INTRODUCTION Therapeutic approach to jaw cysts may depend on their dimensions and localization. Enucleation of cystic lesion is not always preferable in the first act, especially if large cysts are in close proximity to important anatomical structures. The aim of this paper was to present the outcome of the treatment protocol comprising preoperative decompression and subsequent enucleation of a...

The author has experienced a case of microphthalmos with large orbital cyst in a 4 months old female, that was found at the time of birth. To facilitate fitting a cosmetic prosthesis, the microphthalmos with cyst was removed surgically. On serial section I could find an area of discontinuation of the sclera that was suspected to be the defective closure of the embryonic cleft. Some aberrant ret...

BACKGROUND Orbital myositis is a rare extra-intestinal manifestation of inflammatory bowel disease. Seventeen cases of Crohn's disease associated orbital myositis and 3 cases of ulcerative colitis associated orbital myositis have been reported in the published literature since 1970. We report the use of adalimumab (Abbott, Canada, Inc.) for orbital myositis in a patient with Crohn's disease who...

BACKGROUND Conjunctival melanoma is a relatively rare ocular malignancy with substantial associated morbidity and mortality. METHODS More than 100 articles on conjunctival melanoma were reviewed, including most of the relevant recent publications cited in a current MEDLINE search. The author's experience with conjunctival melanomas is also incorporated in this review. RESULTS Recognition of...

Ophthalmic lesions include a wide spectrum of conditions ranging from benign lesions to precancerous lesions and malignant lesions. The diagnosis of these lesions is based on the clinical as well as histopathological features. This was a prospective study of ophthalmic lesions conducted in the department of pathology of Nepal Medial College teaching hospital over a period of one year (September...

through the lower lid as a distinct swelling which becomes decidedly more prominent when the patient looks upwards. On everting the right lower lid, there is an ovoid cyst-like swelling occupying the middle third of the lower part of the ocular conjunctiva. The growth nearly approaches the fornix. It is somewhat adherent to the over-lying conjunctiva, and moves fairly freely over the sclerotic....

We present the case of a full-term girl born to nonconsanguineous parents. Physical examination revealed a large (14 x 6 centimeters) hairless lesion on the right frontalparietal scalp (Fig.1), multiple nodular lesions of the right upper eyelid and eyebrow, and a reddish bulbar conjunctival lesion on the right eye consistent with choriocystoma (Fig.2). A CT scan of the brain showed cranial asym...
