In most offices, those might not be available. But, nowadays, there are a lot of ways of taking good photographs, even without a slit-lamp camera. Be cautious about glaucoma surgery. Tube shunts and microinvasive glaucoma surgery should be avoided in patients with unilateral glaucoma and an iris pigmented lesion, said Dr.
Shields, who urged glaucoma specialists to refer patients to an ocular oncologist to rule out melanoma before surgery. And be cautious about cataract surgery. Be aware of when to pursue cataract surgery in a patient who needs it but has had an iris melanoma. Be aware of radiation side effects.
Comprehensive ophthalmologists are most involved with iris melanoma patients when they are dealing with residual effects from radiation, such as dry eye, healing of the conjunctiva that could create some dry patches on the cornea, or cataract formation in phakic patients.

Richard Mills' Opinions, to Main outcome measures: The main outcome measure was the development of distant tumor metastasis. Cox proportional regression models were used to calculate the risk of eventual metastatic spread. Of the patients with iris melanoma, the mean age at the time of diagnosis was 43 years median, 45 years; range, years.
Histopathology revealed infiltration of most of the iris and pars plicata with largely nonpigmented spindle B cells, consistent with primary iris melanoma with ciliary body involvement. The patient has been followed for more than 10 years and has shown no evidence of metastasis.
Uveal melanoma staging according to the 8th edition of the AJCC Cancer Staging Manual classifies iris melanoma separately from posterior melanoma of the ciliary body and choroid. Iris melanoma is assessed based on several categories, including tumor T , grade G , node N , and metastasis M.
The T category is subdivided by anatomic extent of the iris tumor, with involvement limited to the iris T1a-c or involvement of the ciliary body T2a , choroid T2b,c , sclera T3 , and extrascleral tissues T4a,b Table 1. Each increasing T category is anticipated to signify increasing risk for poor prognosis. The G category is based on histopathologic findings, with spindle cell type G1 , mixed cell type G2 , and epithelioid cell type G3 Table 2.
The N and M categories refer to localized or remote metastasis Tables 3 and 4. Although the AJCC recognizes the prognostic implications of chromosomal analysis and gene expression profiling, the current edition of the manual states that there is not yet a sufficient evidence basis for them to be included in the staging system. Due to the small sample size, Kaplan-Meier estimates were not possible. Since its release in early , there has not yet been analysis of iris melanoma based on the 8th edition of the AJCC Cancer Staging Manual.
This edition provides the first update of iris melanoma staging since the 6th edition, published in Compared with the 6th and 7th editions, the 8th edition has undergone several updates. The T1 and T4 categories were basically unchanged.
The most significant changes pertain to categories T2 and T3. Category T2 was expanded to include subcategories T2a extension into the ciliary body only and T2b extension into ciliary body and choroid. Subcategory T2c now takes on the meaning that category T2a had when it was introduced in the 6th edition T2 with secondary glaucoma , and category T3 has been condensed to involvement of the ciliary body, choroid, or both, with scleral extension T3.
The best way to detect ocular melanoma is to have an annual comprehensive dilated eye exam by a board certified ophthalmologist. This innovative treatment approach now being investigated at Wills Eye Hospital uses viral nanoparticle conjugates, which is a targeted therapy of growing interest in medicine. The treatment involves injecting the AU investigational drug into the eye affected by cancer followed by the brief use of a companion ophthalmic laser treatment to activate the drug.
Currently, the primary treatment option for ocular melanoma is plaque radiotherapy which was, in part, pioneered in the United States by the Shields Oncology team at Wills Eye Hospital.
While that therapy has achieved high success throughout the years in tumor control for patients, this new potential targeted therapy may open the door to a less invasive method of treatment. Wills Eye has always been a leader in the clinical application of emerging new therapies. The trial, which began in early , is expected to enroll up to 12 patients at Wills Eye and other clinical trial sites.
