title: Fundus autofluorescence patterns in type 2A idiopathic juxtafoveolar retinal telangiectasis.
abstract: OBJECTIVE
  To describe fundus autofluorescence (FAF) patterns in patients with type 2A idiopathic juxtafoveolar retinal telangiectasia (IJRT).
  
  
  METHODS
  We reviewed FAF images, color photographs, and fluorescein angiography (FA) images of 30 eyes from 16 patients with type 2A IJRT. Eyes with presence of subretinal neovascularization or any other retinal pathology were excluded. All the imaging modalities were obtained with a Heidelberg Retina Angiograph (HRA) confocal laser scanning system.
  
  
  RESULTS
  The mean age of the patients was 50.7 years, 68.5% female. At baseline, the median best-corrected visual acuity was 20/50. Loss of normal foveal hypoautofluorescence was noted in 93.3% of eyes. All the eyes showed hypoautofluorescence corresponding to intraretinal crystals and pigment clumps. Increased FAF around the pigments was noted in 93.3% of eyes. Increased FAF corresponding to the angiographic leakage from telangiectatic and nontelangiectatic areas was noted in 86.6% of eyes and 80% of eyes, respectively.
  
  
  CONCLUSIONS
  Loss of foveal hypoautofluorescence and increased FAF corresponding to the nontelangiectatic angiographic leakage areas were predominant features. Fundus autofluorescence patterns corresponding to color photography and FA findings may further add to the understanding of morphologic alterations in type 2A nonproliferative IJRT at early stages.
