PURPOSE: To report a case of choroidal metastasis caused by lung cancer in a young female who had no history. CASE SUMMARY: A 31-year-old female presented with decreased vision for 1 week. Fundus examination revealed an orange colored choroidal tumor and serous retinal detachment at superotemporal area of the optic disc on the left eye. On chest X-ray, atypical pneumonia or hematogenous metastasis was shown. Additionally, mammography, chest-abdomen computed tomography, lumbar magnetic resonance imaging, and transbronchial lung biopsy were performed and the patient was finally diagnosed with adenocarcinoma. The patient started systemic chemotherapy and visual acuity improved after 1 month. Tumor size and subretinal fluid also decreased. The tumor disappeared 2 months later and there was no recurrence. CONCLUSIONS: There are only few cases in which choroidal metastasis was observed in a young female patient with no history who had decreased visual acuity and was later diagnosed with lung cancer. Authors report this case because a satisfactory result was obtained from chemotherapy alone.

BACKGROUNDRetinocytoma (RB) is a very common intraocular malignant tumor during infancy. Chemotherapy has gradually been used as the first-line treatment for intraocular RB in recent years. In this study, Livin and PTEN expressions were observed in the RB tissue, along with the growth-inhibiting and apoptosis-induced effects of topotecan (TPT) on RB HXO-Rb44 cell strain. This study aimed to investigate the antigrowth effects of TPT on RB cell strain HXO-Rb44.

METHODSMax-Vision(TM) rapid immunohistochemistry was adopted to detect Livin and PTEN expressions in the normal retina and in RB, and their relationship with RB clinicopathologic features was analyzed. Human RB cell strain HXO-Rb44 was cultivated and passaged. MTT method was used to measure the survival rates of HXO-Rb44 cell strains under various TPT concentrations. IC50 values were calculated. Flow cytometry was used to detect the effects of various TPT concentrations on HXO-Rb44 cell apoptosis. Western blotting was used to detect the differences of Livin and PTEN protein expressions during cell apoptosis.

RESULTSThe positive expressions of Livin and PTEN in the RB group were obviously different from those in the normal control group. In RB tissue, Livin expression was relevant to PTEN expression. TPT could significantly induce the occurrence of cell apoptosis and had a dependent relationship with drug concentration. Livin and PTEN expression levels varied with the extension of the effect time of TPT based on Western blotting analysis.

CONCLUSIONSLivin and PTEN have high and low expression levels in the RB tissue, respectively. Both of them have key roles in RB occurrence and development. TPT could induce human RB cell strain HXO-Rb44 cell apoptosis, and its mechanism is associated with the inhibition of Livin and PTEN expressions.

OBJECTIVETo investigate the safety of treatment with ophthalmic artery cannulation for intra-arterial chemotherapy (IAC) for children with intraocular retinoblastoma (RB).

METHODIn the RB Treatment Center of General Hospital of Armed Police Forces between January 2009 and September 2011, 42 patients who were diagnosed intraocular RB and treated with ophthalmic artery cannulation for IAC, 8 patients were treated 1 circle, 31 patients were treated 2 circles and 3 patients were treated 3 circles (total, 96 times). Each month had IAC once. The ophthalmic and the whole body evaluations were performed during IAC and after IAC for each circle, the blood cell count, alanine aminotransferase (ALT), serum creatinine (Scr), CK-MB content before and after IAC for 1 circle, 2 circles and 3 circles were determined.

RESULT(1) In 52 eyes of 42 patients, 44 eyes (84.6%) were in remission. (2) Successful IAC was achieved in all cases, no severe side effects occurred during IAC. (3) The main ophthalmic complications were eyelid edema and blepharoptosis after IAC, the incidence for 1 circle was 18% (2/11) and 9% (1/11); for 2 circles was 29% (11/38) and 21% (8/38); for 3 circles was all 100% (3/3). The rare complications were vitreous hemorrhage and heterotropia, the incidence was all 2% (1/42). The incidence of eyelid edema and blepharoptosis had no significant differences for 1 circle IAC compared with 2 circles (P > 0.05); the incidence of eyelid edema and blepharoptosis had significant differences for 3 circles IAC compared with 2 circles and 1 circle (P < 0.01). (4) No fever, septicemia and other systemic toxic effects occurred. (5) ALT of 19% patients (8/42) elevated temporarily and CK-MB of 24% patients (10/42) increased. The blood cell counts, ALT, Scr, and CK-MB content before IAC had no significant differences compared with that at 24 h after IAC for 1 circle, 2 circles and 3 circles (P > 0.05).

CONCLUSIONOphthalmic artery cannulation for IAC is a safe and effective method in treating intraocular stage retinoblastoma.

PURPOSE: To evaluate the clinical results of proton beam radiation therapy (PBRT) for treatment of retinoblastoma. METHODS: Children with retinoblastoma who were treated with chemotherapy and focal treatment such as brachytherapy and thermotherapy but showed no response or developed recurrences later received PBRT. The PBRT strategy was designed to concentrate the radiation energy to the retinoblastoma and spare the surrounding healthy tissue or organs. RESULTS: There were three patients who received PBRT. The first patient received PBRT because of an initial lack of tumor regression with chemotherapy and brachytherapy. This patient showed regression after PBRT. The second patient who developed recurrence of retinoblastoma as diffuse infiltrating subretinal seeding was taken PBRT. After complete regression, there was recurrence of tumor and the eye was enucleated. The third patient had unilateral extensively advanced retinoblastoma. Initial chemotherapy failed and tumor recurred. The tumor responded to PBRT and regressed significantly. However, the eye developed sudden multiple recurrences, so we had to perform enucleation. CONCLUSIONS: PBRT for retinoblastoma was effective in cases of showing no response to other treatment modalities. However, it should be carefully applied when there was recurrence of diffuse infiltrating subretinal seeding or extensively advanced retinoblastoma initially.

To describe the clinical and optical coherence tomography (OCT) features of a macular hole (MH) or its precursor lesion in patients treated with systemic antiestrogen agents. We reviewed the medical history of the patient, ophthalmic examination, and both fundus and OCT findings. Three female patients receiving antiestrogen therapy sought treatment for visual disturbance. All of the patients showed foveal cystic changes with outer retinal defect upon OCT. Visual improvement was achieved through surgery for the treatment of MH in two patients. Antiestrogen therapy may result in MH or its precursor lesion, in addition to perifoveal refractile deposits. OCT examination would be helpful for early detection in such cases.

PURPOSE: To evaluate the visual outcomes of retinoblastoma in the posterior pole (RBPP) treated with chemotherapy plus local treatments and to address the prognostic factors that influence such outcomes. METHODS: The medical records of patients with RBPP diagnosed at the Department of Pediatric Ophthalmology, Seoul National University Children's Hospital between August 1987 and September 2007 were reviewed retrospectively. Only those patients treated via primary chemotherapy plus local treatments were included. The presence of foveal involvement and tumors in the posterior pole before and after treatment, the type of regression pattern and the best corrected visual acuity (BCVA) of each patient were evaluated. RESULTS: A total of 13 eyes in 12 patients were included. The mean final BCVA for treated RBPP was 20/210 (range, hand motion to 20/16). However, eight eyes (61.5%) had an acuity of 20/200 or better and seven eyes (53.8%) had an acuity of 20/50 or better. The mean final BCVA was significantly better in cases with negative foveal involvement; however, four eyes (37.5%) with positive foveal involvement had an acuity of 20/200 or better. Tumors area in the posterior pole and the type of regression pattern were not significantly related to final BCVA. CONCLUSIONS: Over one half of the studied RBPP patients had working vision. Although the eyes had RBPP with positive foveal involvement, about one-third of the patients had working vision. Vision preservation should be considered when deciding on RBPP treatment.
