title: Role of echography in diagnostic dilemma in choroidal masses.
abstract: OBJECTIVE
  To evaluate the role of echography in diagnosis and management of a diverse array of choroidal masses.
  
  
  METHODS
  Sixty-two cases of clinically suspected choroidal masses were prospectively analyzed with B-scan (10 Hz), A-scan, and ultrasound biomicroscopy (UBM) (50 Hz) after a meticulous history and ocular examination. Ancillary investigations and systemic evaluation were also done.
  
  
  RESULTS
  Based on clinical suspicion, acoustic features, response to treatment, and other ancillary tests combined together, the various masses were differentiated. The cases included in the study were as follows: n = 10 malignant melanomas, n = 16 metastasis and infiltrations, n = 9 hemangioma, n = 7 tuberculoma, n = 8 nonspecific inflammatory masses, n = 2 disciform plaques, n = 4 macular cysts or retinoschisis, n = 2 Coat's disease, n = 1 melanocytoma, and n = 2 osteomas. Ultrasonography (USG) alone could identify n = 51 lesions, while UBM in combination with USG was needed in remaining 11 masses.
  
  
  CONCLUSIONS
  Standardized echography is an important adjunct in the diagnosis and management of eyes with intraocular masses. A better understanding of the clinicopathological and echographic picture of the diverse lesions can help in detection, differentiation, diagnosis, proposing a therapeutic approach, and also monitoring response to treatment. Echography is essential to evaluate tumors for extrascleral and anterior segment extension.
