Choroidal neovascularization(CNV) secondary to age-related macular degeneration(AMD) occurs in the majority of patients with exudative maculopathy. Using an Indocyanine-green (ICG) angiography system, the authors obtained 24 ICG angiograms with CNV in AMD, and compared them with fluorescein angiograms. CNV was classic in 3 eyes(12.5%) and occult in 21 eyes(87.5%) on fluorescein angiography. The location of the CNV was extrafoveal in 12 eyes(50%), juxtafoveal in 6 eyes(25%) and subfoveal in 6 eyes(25%). Occult CNV was diagnosed in 21 eyes. Of these eyes, 8(38%) had solitary or multifocal hot spot by ICG angiography. Plaques were seen in 13(62%) of these eyes. Occult CNV with pigment epithelial detachment was diagnosed in 7 eyes. In 5 eyes, we were able to detect a well-defined CNV underlying a subretinal hemorrhage. Sixty-seven percentage of eyes with occult CNV could be reclassified as having well-delinated CNV by virtue of the additional findings provided by ICG angiography. But thirty-three percentage of eyes with occult CNV remained ill defined on the ICG angiography. ICG angiography is especially useful in delineating occult neovascularization, neovascularization with overlying subretinal hemorrhage or serosanguineous fluid, and neovasularization associated with pigment epithelial detachments. The results of this study suggest that ICG angiography is a safe test and an important test in evaluation, classification, and laser treatment of patients with occult CNV secondary to AMD.

PURPOSE: The author used optical coherence tomography (OCT) in the identification and classification of choroidal neovascularization to evaluate the potential of this imaging technique for better defining choroidal neovascularization. METHODS: Optical coherence tomography was performed on 20 eyes of 20 patients with the clinical diagnosis of choroidal neovascularization. Its result was compared with fluorescein angiography and indocyanine green angiography RESULTS: Of the 20 eyes, 6 eyes (30%) were identified as classic choroidal neovascularization on fluorescein angiography. Of the 6 eyes, 5 cases were identified as well-demarcated choroidal neovascularization on indocyanine green angiography and optical coherence tomography. One case was identified as fibrovascular pigment epithelial detachment on optical coherence tomograpphy. Of the 13 eyes identified as occult choroidal neovascularization on fluorescein angiography, 6 eyes were identified as well-demarcated choroidal neovascularization on indocyanine green angiography and 7 eyes were identified as well-demarcated choroidal neovascularization on optical coherence tomography. Of the 20 eyes identified as choroidal neovascularization on fluorescein angiography, 3 eyes were missed as choroidal neovascularization on optical coherence tomography. Optical coherence tomography was useful to identify the position and the size of choroidal neovascularization. CONCLUSIONS: OCT was able to distinguish the cross-sectional morphology of various lesions accompanying choroidal neovascularization. This study suggests that OCT may have potential in diagnosing and managing choroidal neovascularization.

PURPOSE: To evaluate long-term treatment outcomes of intravitreal aflibercept monotherapy for polypoidal choroidal vasculopathy (PCV). METHODS: A retrospective review of medical records was performed with 46 patients who were diagnosed with PCV and treated with aflibercept monotherapy for 24 months. Best-corrected visual acuity (BCVA) values measured at diagnosis, 3 months, 12 months, and 24 months were compared. Baseline morphological factors associated with the 24 month BCVA were additionally investigated. RESULTS: The mean age of the patients was 65.8 ± 7.9 years. The patients were treated with a mean of 7.0 ± 2.3 aflibercept injections. The mean logarithm of the minimal angle of resolution (logMAR) BCVA at diagnosis, 3 months, 12 months, and 24 months was 0.56 ± 0.40, 0.36 ± 0.36, 0.45 ± 0.42, and 0.52 ± 0.47, respectively. When compared with baseline values, the BCVA was significantly improved at 3 months (p < 0.001) and 12 months (p = 0.022). However, the value at 24 months was not significantly different (p = 1.000). The BCVA was improved or maintained in 35 eyes (76.1%). Extrafoveal polypoidal lesions were associated with a better 24 month visual outcome than subfoveal/juxtafoveal lesions. CONCLUSIONS: Aflibercept monotherapy was found to be an effective method to maintain or improve long-term visual acuity in PCV patients. The location of polypoidal lesions was a predictive factor for long-term visual outcomes.

PURPOSE: To evaluate the characteristics of patients aged ≥ 90 years who were diagnosed with neovascular age-related macular degeneration (AMD). METHODS: A retrospective review of medical records was performed for 44 patients aged ≥ 90 years diagnosed with neovascular AMD. History of cerebrovascular or cardiovascular disorder and visual acuity at diagnosis were assessed. Fellow eye visual acuity data were also collected. When the fellow eye visual acuity was worse than 0.5, the primary reason for the visual deterioration was identified. RESULTS: The mean patient age was 91.5 ± 1.5 years (range: 90–95 years). Ten (22.7%) patients had histories of cerebrovascular or cardiovascular disorders. The mean logarithm of the minimal angle of resolution (logMAR) of visual acuity was 1.11 ± 0.51 and the visual acuity was worse than 0.1 in 20 eyes (45.5%). The fellow eye visual acuity was worse than 0.5 in 26 eyes (59.1%). The primary reason was neovascular or atrophic AMD in 23 eyes (88.5%). CONCLUSIONS: The incidence of cerebrovascular or cardiovascular disorders was relatively high in patients aged ≥ 90 years. Patients also had poor visual acuity at diagnosis and a high incidence of fellow eye visual deterioration. These systemic conditions should be considered when treating these patients. Additionally, a regular ophthalmic examination is recommended for the early detection of these disorders.

Chronic central serous chorioretinopathy[CSC], which also has been termed diffuse retinal pigment epitheliopathy, is defined as a sensory retinal detachment associated with areas of RPE atrophy and pigment mottling. Fluorescein angiographic finding includes areas of granular hyperfluo-rescence and one or many subtle leaks. In older age group, choroidal neo-vascularization[CNV]may develop as a complication. We investigated the clinical features and performed fluorescein angiography[FAG], indocyanine green[ICG]angiography in 10 patients with CNV among 32 patients with chronic CSC. The location of CNV was extrafoveal[3 eyes]and juxtafoveal[7 eyes]. Associated fundus findings were RPE atrophy[8 eyes], PED[5 eyes], serous RD[4 eyes], subretinal hemorrhage[4eyes]. ICG findings were hypo-fluorescence[8 eyes], choroidal hyperpermeability[7 eyes], choroidal delayed filling[5 eyes]. Choroidal neovascularization was identified only with ICG angiography in 6 out of 10 cases. Laser photocoagulation was performed using ICG angiography in 6 cases. Visual acuity was improved in 4 out of 10 cases, and unchanged in 3 out of 10 cases. Therefore, we suggest that ICG angiography may be used as an important device for the diagnosis and management of CNV in patients with chronic CSC. Visual prognosis of CNV in chronic CSC seems to be relatively good.

OBJECTIVETo establish the diagnostic criteria for polypoidal choroidal vasculopathy (PCV) based on spectral-domain optical coherence tomography (SD OCT) by evaluating the sensitivity and specificity of SD OCT in differentiating PCV from wet age-related macular degeneration (wAMD).

METHODSThe clinical data were reviewed for 62 patients (63 eyes) with the initial diagnosis of PCV or wAMD between August, 2012 and June, 2016. Twenty-four patients (25 eyes) were diagnosed to have PCV and 38 (38 eyes) had wAMD based on findings by fundus photography, fluorescein angiography (FFA) and indocyanine green angiography (ICGA). Among the 6 features of SD OCT, namely a sharp RPED peak, double-layer sign, multiple RPED, an RPED notch, a hyporeflective lumen representing polyps, and hyperreflective intraretinal hard exudates, findings of the first two features and at least one of the other features sufficed the diagnosis of PCV; in the absence of the first two features, the diagnosis of PCV was also made when at least 3 of the other features were present simultaneously. The sensitivity and specificity of SD OCT-based diagnosis were estimated by comparison with the gold standard ICGA-based diagnosis.

RESULTSIn the 25 eyes with an established diagnosis of PCV, 23 eyes (92.0%) met the diagnostic criteria based on SD OCT findings; in the 38 eyes with the diagnosis of wAMD, only 4 eyes (10.5%) met the criteria. The sensitivity and specificity of SD OCT-based diagnosis of PCV was 92.0% and 89.5%, respectively.

CONCLUSIONs We established the diagnostic criteria for PCV based on SD OCT findings with a high sensitivity and specificity. SD OCT shows a strong capacity for differentiating PCV from wAMD.

PURPOSE: To evaluate the long-term treatment outcomes of bevacizumab therapy in patients with myopic choroidal neovascularization (CNV). METHODS: A retrospective review was performed of medical records regarding 43 eyes with myopic CNV that were treated with intravitreal bevacizumab injection. Visual acuity at diagnosis was compared with that measured at the final follow-up; the incidence and timing of re-activation were evaluated. In addition, factors associated with final follow-up were analyzed. RESULTS: Mean patient age was 39.3 ± 12.9 years and mean spherical equivalent (SE) was −11.9 ± 4.4 diopters. Patients were followed-up at a mean of 42.1 ± 17.0 months. Re-activation of the lesion was noted in 17 eyes (39.5%). The mean time to first re-activation was 19.5 ± 15.4 months from the time that resolution of subretinal fluid/retinal fluid was confirmed after initial treatment. The mean visual acuity (the logarithm of the minimal angle of resolution) was 0.40 ± 0.25 at diagnosis and 0.26 ± 0.31 at the final follow-up. Visual acuity at the final follow-up was significantly improved when compared with the baseline value (p = 0.005). Patient age (p < 0.001), SE (p = 0.003), and visual acuity at diagnosis (p < 0.001) were significantly associated with visual acuity at the final follow-up. CONCLUSIONS: Bevacizumab therapy was a useful method for long-term treatment of myopic CNV. The observation of relatively late re-activation after the initial treatment suggests a need for continuous long-term follow-up.

The visual results of laser photocoagulation for subfoveal choroidal neovascular membrane (CNVM) has not always been satisfactory. The surgical removal of the neovascular membrane may be another treatment option. To investigate the prognosis and risk factors of this surgery, we analyzed the results of surgical removal of subfoveal CNVM (23 eyes), subfoveal hemorrhage with CNVM (6 eyes), and subfoveal hemorrhage alone (6 eyes). The mean follow-up period was 17.7 months (range 2 to 47 months). The mean preoperative membrane size was 0.89 disc diameter and the mean postoperative retinal pigment epithelial (RPE) defect size was 1.33 disc diameter. Visual improvement was observed in 13 out of the 23 eyes (56.5%) with sufoveal CNVM, four out of the six eyes (66.6%) with subretinal hemorrhage and CNVM, and five out of the six eyes (83.3%) with subretinal hemorrhage only. The visual outcome of subfoveal CNVM surgery was related to the presence of a subfoveal RPE defect (p = 0.005) rather than to the size of the RPE defect. No recurrence of neovascular membrane was observed during the follow up period. In conclusion, surgical removal may be a good alternative treatment for subfoveal CNVM.

PURPOSE: To evaluate the clinical course of patients who had completed 14 ranibizumab or aflibercept monocular treatments. METHODS: Retrospective medical record analysis was performed to 24 patients who were diagnosed with monocular neovascular age-related macular degeneration and had completed 14 ranibizumab or aflibercept monocular injections, allowed by the Korean National Health Care system. Time to completion was measured along with the percentage and timing of medication switch. Best-corrected visual acuity (BCVA) was measured at the time of diagnosis, after 3-loading injections, and the time of completion. Additionally, we searched for any other factors that had influenced the time to completion. RESULTS: The average time to completion of 14 injections was 32.3 ± 6.2 months (21–48 months). The switching was performed in 17 eyes (70.8%), and it was done after 9.4 ± 2.1 injections (4–14 injections) with prior medication. After 14 injections, the BCVA improved in 6 eyes (25.0%), unchanged in 8 eyes (33.3%), and worsened in 10 eyes (41.7%). Complete resolution of intraretinal fluid and subretinal fluid after 3 loading injections were observed in 20 eyes, and it was significantly related to time to the first recurrence and time to the completion of 14 injections (p = 0.007, r = 0.583). CONCLUSIONS: The average time to completion of 14 injections was 32.3 months, and switching of medication was performed in 70.8%. Longer time to the first recurrence was related to longer completion time. This study will provide useful facts when informing the patients their future treatment plans under the Korean Health Care system.
