Portellos M, Buckley EG. Cataract
surgery and intraocular lens implantation in patients with retinoblastoma.
Arch Ophthalmol. 1998;116:449-452.
Intraocular lens placement in the posterior chamber
of eyes with regressed retinoblastoma and irradiation-induced cataract
seems to be a safe and effective method for the correction of aphakia.
Finger PT. Microwave thermo-radiotherapy
for uveal melanoma: results of a 10-year study. Ophthalmology. 1997;104:
1794-1803.
Adjuvant microwave thermotherapy can be used with
reduced doses of ophthalmic plaque radiation therapy to control the growth
of uveal melanomas. The visual acuities of microwave plaque thermo-therapy-treated
eyes were found to be superior to those treated with radiation alone.

S, et al. Metastatic risk for distinct patterns of postirradiation local
recurrence of posterior uveal melanoma. Ophthalmology. 1997;104:1785-1792.
Postirradiation local recurrence of posterior uveal
mel-anoma is a risk factor for systemic metastasis. Vertical/diffuse recurrences
may be associated more strongly with metastatic disease than are horizontal/marginal
recurrences.

DH, et al. Cancer Incidence after retinoblastoma. Radiation dose and sarcoma
risk. JAMA. 1997;278: 1262-1267.
Genetic predisposition has a substantial impact on
risk of subsequent cancers in retinoblastoma patients, which is further
increased by radiation treatment. Retinoblastoma patients should be examined
for new cancers and followed into later life to determine whether their
extraordinary cancer risk extends to common cancers of adulthood.

G, et al. Chemotherapy with focal therapy can cure intraocular retinoblastoma
without radiother-apy. Arch Opthalmol. 1996;114: 1321-1328.
This pilot study suggests that most retinoblastomas
are curable by combining chemotherapy with cyclosporine therapy, laser
therapy, and cryotherapy without requiring external-beam radiotherapy.
The Collaborative Ocular Melanoma
Study Group. Factors predictive of growth and treatment of small choroidal
melanoma: COMS Report No. 5. Arch Ophthalmol. 1997;115:1537-1544.
Of small choroidal melanomas initially managed by
observation, 21% demonstrated growth by two years and 31% by five years.
The clinical and photographic features of these tumors confirm previous
findings and are useful in identifying patients with small tumors at highest
risk of short-term growth.

JT, et al. Intravitreal methotrexate as an adjunctive treatment of intraocular
lymphoma. Arch Ophthalmol. 1997;115:1152-1156.
The role of ocular radiation therapy must be weighed
against the potential drawbacks. Injecting chemotherapeutic agents into
the vitreous is worthy of consideration. Four patients treated to date
at the authors institution have shown promising results. Intravitreal
chemotherapy may result in improved treatment of intraocular lymphoma with
reduced morbidity.
The Collaborative Ocular Melanoma
Study Group. Mortality in patients with small choroidal melanoma: COMS
Report No. 4. Arch Ophthalmol. 1997;115:886-893.
Otherwise healthy patients with an average age of
60 years and without a previous diagnosis of malignant disease who have
small choroidal lesions judged to be melanoma have a low risk of dying
within five years.

CL, et al. External beam irradiation for choroid metastases: identification
of factors predisposing to long-term sequelae. Int J Radiat Oncol Biol
Phys. 1997;38:251-256.
Despite a variety of external-beam radiotherapy treatment
(EBRT) techniques and the proximity of choroidal metastases to radiosensitive
structures, complications of palliative EBRT were infrequent. Complications
that do occur are related to host factors and do not appear to be a function
of irradiation parameters.

CL, et al. Functional vision is improved in the majority of patients treated
with external-beam radiotherapy for choroid metastases: a multivariate
analysis of 188 patients. J Clin Oncol. 1997;15: 1244-1251.
External-beam radiotherapy restores and maintains
useful vision in patients with choroid metastases, with a globe preservation
rate of 98%. Patients who are less that 55 years of age with pretreatment
visual acuity better than 20/60 and tumor diameter less than 15 mm are
most likely to benefit from this intervention.
