| Popis: | Uveal melanoma is the most common primary malignancy of the eye in Caucasian adults, of which choroidal melanoma is the most common subtype.1 Ciliary body melanoma is a rare tumour seen in 1 out of 10 cases of all intraocular melanomas with an average age of 55 to 62 years.2, 3 Uveal melanoma arises from atypical melanocytes present in iris, ciliary body and choroid, although each tumour has some particular characteristics depending on its location and structure. Because of the continuous contractions of the ciliary muscle and rich vascularization of the ciliary body, metastasis is faster in ciliary body melanoma.2 Vascular metastasis leads to impairment of other organs which is the main cause of death among ciliary body melanoma patients with 10 year mortality rate being 30-50%.2 Ciliary body melanoma has the worst prognosis of all intraocular tumours due to early hematogenous metastasis which are frequently seen in the first year after diagnosis. A 55-year-old male patient, farmer by occupation, residing in Bhilawara district of Rajasthan state, India presented with complaint of diminution of vision, pain and redness in right eye since 2 months with aggravation of symptoms since last 3 days. The patient was asymptomatic before 2 months, when he noted gradual diminution of vision and redness in the right eye. This gradually progressed to severe pain, increasing redness and gradual, progressive loss of vision over the last 3 days. The patient had no significant past medical history or family history. There was no history of trauma, use of prescription glasses, foreign body, previous eye diseases or eye surgery. On examination, the best corrected visual acuity in right eye was counting finger 3 meters without glasses which was not improving with pin hole or glasses and in left eye 6/12 with -1.00D spherical glasses for far vision and N8 with +2.50 D spherical glasses. On slit-lamp examination, lid and lacrimal apparatus were normal in both eye. Right eye showed conjunctival congestion, generalized corneal oedema with the shallow anterior chamber temporally. Iris chafing with bulge and iridocorneal contact was seen on temporal aspect and hyphema of approximately 2 mm in size was present in the right eye. Pupil was semi dilated, fixed and not reacting to light with multiple posterior synechiae and blood-stained anterior lens capsule with cataractous lens changes were seen in the right eye. Anterior segment of left eye appeared normal. |
