Exudative retinal detachment is the most common source of visual loss associated with malignant melanoma of the uveal tract. Management has historically been conservative, leading to irreversible visual loss from photoreceptor damage during the several months needed for post-radiation resolution. The purpose of this paper is to describe timely vitreoretinal surgical intervention for exudative retinal detachments associated with choroidal melanomas. This was an interventional case series including six consecutive patients with malignant melanoma who experienced VA reduction secondary to associated exudative retinal detachment. Patients underwent complete ophthalmic evaluation and B-scan ultrasound. Treatment included proton-beam radiation or brachytherapy, prognostic transretinal tumour biopsy with 25-gauge vitrector and surgical treatment of exudative retinal detachment, including vitrectomy and drainage of subretinal fluid at the time of irradiation. Successful management of exudative retinal detachments associated with choroidal melanomas was observed in all cases, with significant restoration of vision. Steady regression of tumour thickness was noted clinically and ultrasonographically, without extrascleral extension or metastasis, and with no recurrence of exudative retinal detachment found over follow up. In the present study, the investigators have showed effective surgical treatment of exudative retinal detachment associated with malignant melanoma. These patients had significant restoration of vision, confirming that timely intervention of exudative retinal detachment associated with malignant melanoma can reverse visual loss in these patients. These findings are in contrast to previous reports of irreversible visual loss after exudative retinal detachments, and suggest that photoreceptor atrophy might play a role in visual loss associated with chronic exudative retinal detachments.

UI MeSH Term Description Entries
D008297 Male Males
D008545 Melanoma A malignant neoplasm derived from cells that are capable of forming melanin, which may occur in the skin of any part of the body, in the eye, or, rarely, in the mucous membranes of the genitalia, anus, oral cavity, or other sites. It occurs mostly in adults and may originate de novo or from a pigmented nevus or malignant lentigo. Melanomas frequently metastasize widely, and the regional lymph nodes, liver, lungs, and brain are likely to be involved. The incidence of malignant skin melanomas is rising rapidly in all parts of the world.

D008875 Middle Aged An adult aged 45 - 64 years. Middle Age
D012163 Retinal Detachment Separation of the inner layers of the retina (neural retina) from the pigment epithelium. Retinal detachment occurs more commonly in men than in women, in eyes with degenerative myopia, in aging and in aphakia. It may occur after an uncomplicated cataract extraction, but it is seen more often if vitreous humor has been lost during surgery.

D001918 Brachytherapy A collective term for interstitial, intracavity, and surface radiotherapy. It uses small sealed or partly-sealed sources that may be placed on or near the body surface or within a natural body cavity or implanted directly into the tissues.

D002830 Choroid Neoplasms Tumors of the choroid; most common intraocular tumors are malignant melanomas of the choroid. These usually occur after puberty and increase in incidence with advancing age. Most malignant melanomas of the uveal tract develop from benign melanomas (nevi).

D005122 Exudates and Transudates Exudates are fluids, CELLS, or other cellular substances that are slowly discharged from BLOOD VESSELS usually from inflamed tissues. Transudates are fluids that pass through a membrane or squeeze through tissue or into the EXTRACELLULAR SPACE of TISSUES. Transudates are thin and watery and contain few cells or PROTEINS.
