RESUMO

OBJECTIVE: To report the long-term therapeutic results for patients with conjunctival mucosa-associated lymphoid tissue (MALT) lymphoma who were treated with intralesional injections of interferon-α (IFN-α). DESIGN: Prospective, nonrandomized, interventional case series. PARTICIPANTS: Twenty eyes of 16 patients with histologically proven conjunctival MALT lymphoma in the absence of systemic disease. METHODS: Patients were given 1,500,000 international units (IU) of IFN-α (Roferon-A; Roche s.p.a., Milano, Italy) subconjunctivally inside the lesion 3 times weekly for 4 weeks. If there was even a minimal response, a further cycle of 1,000,000 IU 3 times weekly for 4 weeks was administered. MAIN OUTCOME MEASURES: Patients were followed up clinically using slit-lamp examination to determine evidence of tumor disappearance or recurrence. In 10 eyes, an incisional biopsy was performed 6 months after therapy to verify the histologic absence of the lesion. RESULTS: A complete response was obtained in 15 eyes (75%) at the end of first cycle treatment, and in 5 eyes (25%) after further cycles. Seventeen eyes (85%) showed no local recurrence after a median follow-up of 65 months (range, 15-136 months). Three eyes (15%) demonstrated recurrence at variable points after treatment. One patient with stage IIA lymphoma exhibited systemic lymphoma progression. CONCLUSIONS: Local immunotherapy with IFN-α seems to be an effective and lasting treatment method and provides an alternative to radiotherapy for conjunctival MALT lymphomas. Very few transient side effects were detected.

RESUMO

OBJECTIVE: To evaluate the long-term efficacy of verteporfin photodynamic therapy (PDT) as the primary treatment for symptomatic circumscribed choroidal hemangioma (CCH). DESIGN: Prospective consecutive, 2-centered, noncomparative, interventional case series. PARTICIPANTS: Twenty-five subjects with symptomatic CCH. All patients had recent onset of visual symptoms and evidence of exudative macular changes on fluorescein angiography (FA) and optical coherence tomography (OCT). METHODS: Verteporfin 6 mg/m(2) body surface area was administered intravenously over a 10-minute interval. Five minutes after infusion, a 689 nm laser was applied with a light dose of 50 J/cm(2) for the first 3 patients and a light dose of 100 J/cm(2) for all the other patients. Retreatments were performed in case of persistent exudation found on OCT. Evaluation of best-corrected visual acuity (BCVA) using Early Treatment of Diabetic Retinopathy Study (ETDRS) criteria, FA, indocyanine green angiography (ICGA), OCT, and ultrasound were performed before PDT and on follow-up examinations. All patients were followed for at least 5 years. MAIN OUTCOME MEASURES: Primary outcome measures were changes in BCVA and foveal center thickness (FCT) between baseline and month 60. Secondary measures were tumor thickness decrease, absence of leakage on FA, and adverse events. RESULTS: Twenty-two patients received 1 PDT session at 100 J/cm(2), and no recurrences were detected. Three eyes, treated with 50 J/cm(2), received a second PDT session at 100 J/cm(2) 1 month after the first session. After a follow-up of 60 months, BCVA improved an average of 18.5 ETDRS letters (P<0.001); BCVA improved by > or =2 lines in 19 eyes (76%). The FCT decreased from a mean of 386.20 microm to 179.2 microm, and OCT showed the complete resolution of macular exudation in all cases. All tumors responded with a reduction in size. No treatment-related adverse events or complications were identified. CONCLUSIONS: The 5-year results of PDT in treating symptomatic CCH support treatment with a light dose of 100 J/cm(2) after slow intravenous infusion of verteporfin to stabilize or improve visual acuity and resolution of macular exudation.

RESUMO

PURPOSE: The purpose of this study was to evaluate 1-year functional and structural effects of intravitreal bevacizumab for subfoveal choroidal neovascularization secondary to pathologic myopia (myopic choroidal neovascularization). METHODS: Fifteen eyes with myopic choroidal neovascularization participated in this prospective interventional, noncomparative case series. All patients were treated with one intravitreal injection of 1.25 mg bevacizumab. Retreatments were performed in case of persistent or recurrent leakage on fluorescein angiography and/or intraretinal fluid on optical coherence tomography. Evaluation of best-corrected visual acuity using Early Treatment of Diabetic Retinopathy Study criteria, MP-1 microperimetry, optical coherence tomography, and fluorescein angiography were performed before treatment and 1 month, 3 months, 6 months, and 1 year after treatment. RESULTS: After a follow-up of 12 months, best-corrected visual acuity improved on average of 0.23 logarithm of the minimum angle of resolution. Mean macular sensitivity within the central 8 degrees increased on average of 2.62 dB at 12-month postinjection. The mean number of measurement points within the central absolute scotoma reduced significantly from 12.47 before treatment to 6.27 at 1-year follow-up. An improvement of fixation stability from baseline was observed in 9 patients (60%). No treatment adverse events were evidenced. CONCLUSION: Improvement of macular sensitivity and fixation stability 1 year after intravitreal bevacizumab for myopic choroidal neovascularization suggest a stable and progressive macular function recovery. The mean treatment session was 1.53, with 53.3% of patients needing only a single intravitreal bevacizumab injection, supporting a potential long-lasting efficacy of intravitreal bevacizumab treatment.

RESUMO

Spectral-domain optical coherence tomography serial changes in three cases of spontaneous closure of idiopathic macular hole at stages II, III, and IV are described. Initial and serial spectral-domain optical coherence tomography images document the progressive closure. Macular holes apparently resolved spontaneously through two different mechanisms: posterior hyaloid detachment in case 1 and a contraction of epiretinal macular membrane in cases 2 and 3. The spontaneous closure of idiopathic full-thickness macular holes may occur in any stage of idiopathic macular hole; the small size of the hole is a common feature in all cases of spontaneous closure reported.

RESUMO

PURPOSE: To report a case of a lymphoepithelioma-like carcinoma (LELC), which is a variant of carcinoma most commonly involving the nasopharynx and rarely occurring in a variety of sites outside its typical location. METHODS: We present the case of a 79-year-old Caucasian man with LELC of the lacrimal gland undergoing surgical resection of the mass. RESULTS: The patient had remained disease-free for 2 years, and then he developed homolateral metastases in latero-cervical and parotid lymph nodes, detected by computed tomography and confirmed by fine-needle aspiration biopsy. He did not receive any surgical treatment, radiotherapy, or chemotherapy because of the advanced stage of the disease and poor health condition. CONCLUSIONS: This case report suggests that a diagnosis of lacrimal gland LELC makes combined early and radical therapy necessary.

RESUMO

PURPOSE: To report our experience with photodynamic therapy (PDT) with verteporfin for patients with vasoproliferative retinal tumors (VPRTs). METHODS: Three patients with VPRTs who presented with macular exudative changes were treated with one session of PDT with 6 mg/m body surface area of verteporfin and a light dose of 100 J/cm at 689 nm delivered in 166 seconds. Biomicroscopy, fluorescein angiography, indocyanine green angiography, optical coherence tomography, and ultrasonography were performed before treatment and 1 month, 3 months, 6 months, and 1 year after treatment; visual acuity was measured using Early Treatment Diabetic Retinopathy Study criteria. RESULTS: At the 1-year follow-up, all tumors responded with a reduction in size (mean height: pretreatment, 2.96 mm; posttreatment, 1.32 mm), and optical coherence tomography showed complete resolution of macular exudates. For all patients, fluorescein angiography evidenced reduction of leakage from the lesion, and indocyanine green angiography verified nonperfusion of the vascular channels. An improvement in visual acuity (average, 4.7 Early Treatment Diabetic Retinopathy Study letters) was observed. No retreatment was needed. CONCLUSION: PDT may represent an effective and safe modality of treatment for VPRTs because of its selectivity. Our study supports the application of a light dose of 100 J/cm, although further studies with larger numbers of cases and longer follow-ups are required.

RESUMO

PURPOSE: To describe a case of choroidal neovascularization (CNV) after laser in situ keratomileusis (LASIK) following penetrating keratoplasty (PK). METHODS: Case report. RESULTS: A 30-year-old man underwent PK in both eyes for bilateral keratoconus in 1997. Two years later, best-corrected visual acuity (BCVA) was 20/40 (-6=-4.50 x 170 degrees ) in RE and 20/20 (-1.50=-0.50 x 90 degrees ) in LE. To reduce the anisometropic defect, LASIK was performed in RE. After surgery, the refractive defect in RE reduced to -1.75 x 125 degrees and BCVA improved to 20/25. Six months after LASIK the patient presented loss of vision and metamorphopsia in RE due to choroidal neovascularization. BCVA was reduced to 20/200. Photodynamic therapy was performed in RE; 1 year later BCVA was stable at 20/200. CONCLUSION: Vitreoretinal complications after LASIK occur rarely. The potential relationship between CNV and LASIK is discussed.
