RESUMEN

Objective. To report the visual and anatomic outcomes of pneumatic displacement with perfluoropropane (C3F8) gas and intravitreal tissue plasminogen activator (IVTPA) for subretinal subfoveal hemorrhage after focal laser photocoagulation in central serous chorioretinopathy (CSCR). Method. Interventional, retrospective case report of one eye (one patient). Outcome measures included visual acuity (VA), central macular thickness (CMT), and size of the lesion at two weeks of followup. Fluorescein angiography (FA) and optical coherent tomography (OCT) were used to measure anatomic outcomes. Results. A 35-year-old man with history of chronic CSCR received focal laser photocoagulation in the right eye two days before presentation. At initial examination, VA was 20/200 (ETDRS chart), CMT was 398 µ, and a subretinal subfoveal hemorrhage was seen. Tissue plasminogen activator (tPA) at a dose of 25 µg/0.1 mL was injected intravitreally before intravitreal C3F8 injection, and prone positioning was indicated postoperatively. At 24 hours, the hemorrhage had been displaced inferiorly and VA improved to 20/100. Two weeks later, VA improved to 20/80, CMT decreased to 225 µ, and the hemorrhage decreased without foveal involvement. Conclusions. The technique seems safe and effective in treating visually significant subretinal subfoveal hemorrhage.

RESUMEN

Ocular toxocariasis is an uncommon worldwide parasitic infection that affects mostly children and is found in both rural and metropolitan areas. In many parts of the world, parasitic infections of the eye are a major cause of blindness. The diagnosis of toxocariasis is essentially clinical, based on the lesion morphology and supportive laboratory data such as serum enzyme-linked immunosorbent assay (ELISA) titers and ELISA Toxocara titers on aqueous humor; other diagnostic methods are imaging studies including optical coherence tomography, fluorescein angiography, computed tomography, and ocular ultrasound. Treatment is directed at complications arising from intraocular inflammation and vitreous membrane traction. Early vitrectomy may be of value both diagnostically and therapeutically.

RESUMEN

PURPOSE: To report the effectiveness of indocyanine green mediated photothrombosis (IMP) combined with high dose (4 mg/0.16 ml) intravitreal bevacizumab (IVB) as adjunctive therapy for management of isolated choroidal metastasis from breast cancer. METHODS: This retrospective interventional case report includes three eyes of two patients with choroidal metastasis from breast cancer. Both patients were submitted to one session of IMP combined with high dose IVB as adjuvant local therapy to systemic chemotherapy. Main outcome measures were tumor response, and fluorescein angiography (FA), optical coherence tomography (OCT), and visual acuity (VA) results. RESULTS: The first patient was a 47-year-old woman who had undergone radical mastectomy, chemotherapy and radiotherapy 7 years earlier and the second patient was a 70-year-old woman managed with chemotherapy and radiotherapy 16 years before presentation. There was no evidence of systemic metastasis in either case and both suffered from gradually blurred vision. The first patient presented with a unilateral choroidal lesion whereas the second case had bilateral unifocal choroidal lesions which was symptomatic in only one eye. Clinical examination, ultrasonography, FA, and OCT revealed accompanying exudative retinal detachment in all three eyes. OCT 3 to 5 weeks after combined therapy demonstrated complete resolution of subretinal fluid and improved VA in two eyes. CONCLUSION: Combined IMP and high-dose IVB seems to be an effective adjunctive treatment to systemic chemotherapy for management of isolated choroidal metastasis from breast cancer.

RESUMEN

BACKGROUND: To report the anatomic and functional outcomes of a single-session combined photodynamic therapy with verteporfin (PDT) and intravitreal (IVT) anti-vascular endothelial growth factor (anti-VEGF) in patients with chronic central serous chorioretinopathy (CCSCR). METHODS: Retrospective interventional comparative case series of eyes with symptomatic CCSCR (duration ≥ 4 months) and macular neurosensory retinal detachment (MNSRD). The study group, eight eyes (six patients), received a single session of combined full-fluence PDT and IVT anti-VEGF [bevacizumab (2.5 mg), four eyes; pegaptanib sodium [0.3 mg], four eyes). A matched control group, ten eyes (seven patients), treated with full-fluence PDT alone, was included. All patients had 12 months of follow-up. RESULTS: The mean CCSCR duration was 12.5 ± 14.2 months (range: 4-47 months) in the study group. In the control group, the mean CCSCR duration was 15.3 ± 7.5 months (range: 4-24 months). In the study group, the mean logarithm of the minimum angle of resolution (logMAR) best-corrected visual acuity (BCVA) improved from 0.6 (20/80) to 0.2 (20/30) (P = 0.011). Central macular thickness (CMT) measured by optical coherence tomography (OCT) decreased from 288.4 µ (range: 165-375 µ) at baseline to a CMT of 163.1 µ (range: 120-200 µ) (P = 0.005) at 12 months. In the control group, the mean logMAR BCVA improved from 0.7 (20/100) to 0.6 (20/80) (P = 0.43). CMT decreased from 332.9 µ (range: 171-495 µ) at baseline to a CMT of 213.1 µ (range: 133-307 µ) (P = 0.002) at 12 months. At 12 months, MNSRD resolved completely in eight eyes (100%) and in seven eyes (70%), in the study group and the control group respectively. In the control group, four eyes (40%) required more than one PDT session (mean: 2.6 sessions; range: 2-4) due to persistent MNSRD. Retinal pigment epithelium (RPE) atrophy changes but no leakage were seen by fluorescein angiography in all eight eyes (100%) in the study group, and in three out of ten eyes (30%) in the control group. No systemic adverse events were observed. CONCLUSIONS: Combined PDT and IVT anti-VEGF therapy seems to aid in the resolution of MNSRD in patients with CCSCR. Combination therapy was associated with a rapid reduction in MNSRD and improvement in BCVA with no recurrences at 12 months. However, combination therapy with full-fluence PDT has the potential to accelerate RPE atrophy, and this needs further study.

RESUMEN

BACKGROUND: To evaluate the anatomical and functional outcomes of intravitreal bevacizumab (1.25 or 2.5 mg) in the treatment of inflammatory choroidal neovascularization at 24 months. METHODS: We reviewed the clinical records of 22 consecutive patients (23 eyes) with choroidal neovascularization secondary to chorioretinal inflammatory disease in this interventional retrospective multicenter case series. Sixteen eyes (63.6%) received a dose of 1.25 mg of intravitreal bevacizumab, and 7 eyes (36.4%) received a dose of 2.5 mg of intravitreal bevacizumab. RESULTS: At baseline, the mean best-corrected visual acuity was 0.68 logarithm of minimum angle of resolution (Early Treatment Diabetic Retinopathy Study chart = 20/100). After intravitreal bevacizumab, best-corrected visual acuity improved significantly to 0.41 logarithm of minimum angle of resolution (20/51), 0.42 logarithm of minimum angle of resolution (20/53), and 0.40 logarithm of minimum angle of resolution (20/50) at 6, 12, and 24 months, respectively (P < 0.05). Fourteen eyes (60.8%) received 1 injection. Central macular thickness by optical coherence tomography decreased from 375.3 µm (range: 240-634 µm) at baseline to 241.6 µm (range: 189-306 µm) at 24 months of follow-up (P < 0.0001). CONCLUSION: Intravitreal bevacizumab at doses of 1.25 mg and 2.5 mg seems to provide stability or improvement in best-corrected visual acuity, optical coherence tomography, and fluorescein angiogram in inflammatory choroidal neovascularization at 24 months. All patients were treated after the underlying uveitic condition was controlled.
