Purpose:To investigate the ease and use of the mosaic fundus image in clinical practice and determine the benefit of this modality for visualization and treatment of retinal diseases. Methods:Fifty patient with posterior fundus and peripheral retinal disease were seen at Denver Health Medical Center over the course of one year. All patients had comprehensive ophthalmological examsinations inclusive of visual acuity, intraocular pressure, slit lamp and dilated fundus examination. Digital color fundus photographs were obtained for all patients using the 50–degree field of view. When necessary digital fluorescein angiography was obtained also using the 50 –degree field of view. Digital montages were constructed using mosaic software for both color and fluorescein angoigrams. Six to nine seperate images were averaged for each montage taking an average of 10 to 30 minutes to construct the montage. Results: The photographs used covered a variety of diagnoses. Of particular interest were mosaics of the following pathologies: proliferative diabetic retinopathy with tractional detachment, Harada'disease with a bullous, dependent neurosensory detachment, Coat's disease, and retinal toxocity secondary to inadvertent gentamicin injection.. The mosaic images provided an enhanced view in all cases. The mosaic technique was beneficial for documentation of the entire retinal pathology and increased our ability to determine the correct diagnosis and treatment. Montage photographs were also used to illustrate to the patient and family the full extent of the retinal disease. The time spent creating the montage was not unduly long, and so was not a deterrent. Conclusions: Mosaic fundus imaging is a valuable imaging modality for visualization, diagnosis and documentation of diffuse retinal diseases. Compared to more traditional fundus photography it offers the advantage of displaying the fundus in one big picture. This can be used for clinical and teaching purposes.
