case_images: Fundus photographs and spectral domain optical coherence tomography (SD-OCT)
  images of the case: (a) normal examination of the right eye; (b) hard
  exudates, microaneurysms, and a few intraretinal hemorrhages were seen
  around the macula in the left eye; and (c) SD-OCT showed cystoid macular
  edema and serous macular detachment.

case_images: fig1-2515841419848945
case_images: The right eye was normal (Figure 1(a) and (b)). SD-OCT showed cystoid macular edema and serous macular detachment (Figure 1(c)).
case_images: Fundus fluorescein angiography (FFA) images of the case. (a) Arteriovenous
  phase of the FFA at 15 s. Upper blue arrow shows the superior temporal
  artery, and lower blue arrow shows the inferior temporal vein. Laminar flow
  pattern with a railroad track appearance was seen in the filling venules.
  (b) Still arteriovenous phase of the FFA at 17 s. Red arrow shows an
  anastomosis between the inferior venous vascular arcade and the superior
  arterial vascular arcade. (c) Venous phase of the FFA at 32 s. Red arrow
  shows giant arteriovenous aneurysmal malformation with a bean-like
  morphology. Blue stars show telangiectatic capillaries and dilated
  collateral venous channels across the horizontal raphe between inferior and
  superior vascular arcades.

case_images: fig2-2515841419848945
case_images: FFA showed bean-like arteriovenous aneurysmal anastomosis between the inferior venous vascular arcade and the superior arterial vascular arcade (Figure 2(a) and (b)). FFA also showed telangiectatic capillaries around the macula (Figure 2(c)).
case_images: Optical coherence tomography angiography (OCTA) images of the case: (a)
  superficial capillary plexus segmentation, (b) deep capillary plexus
  segmentation, (c) outer retina segmentation of the case, and (d) color
  overlay images of the lesion. The yellowish part of the image shows the
  malformation located in the outer retina.

case_images: fig3-2515841419848945
case_images: OCTA revealed flow voids in the arteriovenous aneurysmal malformation and en face angiogram within the deep capillary plexus, which showed venous collateral channels across the horizontal raphe (Figures 3-5).
case_images: En face images of the case via optical coherence tomography angiography: (a)
  superficial capillary plexus segmentation, (b) deep capillary plexus
  segmentation, and (c, d) outer retina segmentation of the case. In (b), red
  arrows show collateral venous vessels across the horizontal raphe between
  inferior and superior vascular arcades.

case_images: OCTA revealed flow voids in the arteriovenous aneurysmal malformation and en face angiogram within the deep capillary plexus, which showed venous collateral channels across the horizontal raphe (Figures 3-5).
case_images: Optical coherence tomography angiography (OCTA) revealed flow voids within
  the arteriovenous aneurysmal malformation (red line) in deep capillary
  plexus and avascular outer retina: (a) manual segmentation of OCTA through
  the outer retina and (b) en face angiogram of OCTA after the aflibercept
  therapy.

case_images: OCTA revealed flow voids in the arteriovenous aneurysmal malformation and en face angiogram within the deep capillary plexus, which showed venous collateral channels across the horizontal raphe (Figures 3-5).
case_images: Spectral domain optical coherence tomography (SD-OCT) changes during the
  follow-up: (a) SD-OCT image at baseline examination; (b-d) SD-OCT images at
  first-, second-, and third-month examinations, respectively; (e) SD-OCT
  image at the sixth-month examination after the fifth intravitreal injection
  of aflibercept; and (f) SD-OCT image at the 12th-month examination.
