Myopic Choroidal Neovascularization

Purpose: To evaluate the agreement between fluorescein angiography and structural optical coherence tomography in diagnosing and monitoring the activity of myopic choroidal neovascularization and to provide a comparative analysis with optical coherence tomography angiography. Methods: Thirteen patients with active myopic choroidal neovascularization were prospectively enrolled. At the baseline, 2-month, and 6-month visits, each patient underwent a complete ophthalmological examination, including best-corrected visual acuity assessment, fundus examination, fluorescein angiography, and optical coherence tomography with structural and angiographic assessment. Sensitivity and specificity for all optical coherence tomography parameters were evaluated taking fluorescein angiography as the reference examination. Results: At the baseline, fluorescein angiography confirmed myopic choroidal neovascularization leakage in all patients. Structural optical coherence tomography demonstrated intraretinal or subretinal fluid in 61% of cases, fuzzy borders and absence of external limiting membrane visibility in 84% of cases, and subretinal hyperreflective exudation in 53% of cases. Sensitivity to the presence of retinal fluid and subretinal hyperreflective exudation was lower than sensitivity to fuzzy borders and external limiting membrane visibility, which reached 84%. During ranibizumab therapy, external limiting membrane visibility showed a higher sensitivity (100%) compared with fuzzy borders and subretinal hyperreflective exudation (66.6%) while displaying an equal specificity of 100%. At baseline and final visit, sensitivity increased to 100% when all structural optical coherence tomography parameters were pooled. Optical coherence tomography angiography detected myopic choroidal neovascularization at baseline, 2-month, and 6-month visits in 92%, 76%, and 76% of cases, respectively. Conclusion: The study confirms that the new indicators of myopic choroidal neovascularization activity are more reliable than the presence or absence of retinal fluid. Optical coherence tomography angiography identified myopic choroidal neovascularization in most patients in the diagnostic phase and during treatment monitoring and could be considered as an alternative to fluorescein angiography in selected patients.

Abstract Age-related macular degeneration is a leading cause of irreversible vision loss in individuals over 55 years of age worldwide. Conventionally, it is divided into two subtypes – dry (non-neovascular) and wet (neovascular) form. Neovascular age-related macular degeneration comprises only 10-15% of all patients but is responsible for more than 80% of blindness related to the disease. It requires early diagnosis and timely treatment. Fluorescein angiography is the current ‘gold standard’ for diagnosing neovascular forms. However, as an invasive procedure, it may be contraindicated in some circumstances and cause serious adverse effects. Optical coherence tomography-angiography is a relatively new, non-invasive and fast imaging modality gaining popularity in the diagnosis of age-related macular degeneration, especially for the neovascular form of the disease. It enables structural and functional information of blood vessels in the retina and choroid, without the need of an intravenous dye. In this study we present and discuss 3 cases of different subtypes of choroidal neovascularization secondary to neovascular age-related macular degeneration. All of them were examined by fluorescein angiography and optical coherence tomography-angiography. The results were qualitatively analyzed.

Abstract Background The current study aimed to evaluate the efficacy of intravitreal aflibercept injections as the primary treatment for subfoveal/juxtafoveal myopic choroidal neovascularization (CNV) by using optical coherence tomography (OCT). Optical coherence tomography angiography (OCTA) was further used for some patients to detect the changes of CNV after treatment. Methods In the present study, 21 treatment-naive eyes of 21 patients with subfoveal/juxtafoveal myopic CNV received primary intravitreal aflibercept injections and were under follow-up for a minimum duration of 12 months. Among the 21 patients, 12 underwent OCTA to evaluate the changes in central foveal thickness, selected CNV area, and flow area. Results The mean best-corrected visual acuity (BCVA) pertaining to all the patients significantly improved from the baseline value of 0.7 to 0.3 logMAR after treatment for 12 months (P = 0.001). However, the improvements in the median BCVA after treatment for three and 12 months were not statistically significant in the younger group (< 50 years), compared to the older group (≥ 50 years). One aflibercept injection resolved the CNV in 47.6% (10/21) of the patients. The younger group displayed greater improvement in the median central foveal thickness, compared to the older group. OCTA revealed interlacing or disorganized pattern at the level of the outer retinal layer in 12 subjects with myopic CNV. After 3 months of treatment, both groups displayed a decrease in the size of the selected CNV area and flow area. The interlacing group displayed a trend towards better anatomical improvements. Conclusion Intravitreal aflibercept injection provides long-term improvement in visual acuity in patients with myopic CNV. Eyes with the interlacing pattern on OCTA displayed a greater decrease in size and flow after aflibercept injection. Trial registration Before data collection, written informed consent was obtained from each participant, whose identity information was protected by encryption and conversion to a non-identifiable format and removing data links. This study was approved by the Institutional Review Board of Kaohsiung Veterans General Hospital (KSVGH21-CT1–17).
