Microcomputer applications in pathology research

In a study of over 700 cases of uveal melanoma on file in the Department of Pathology of Wills Eye Hospital, a low-cost microcomputer using commercially available software (without modification) was used to: word process and edit this manuscript, create a patient file storage and retrieval system including the ability to create subfiles, merge files, and interchange file types, plot data points in several different graphic formats, transcribe and store information from microscopic tissue sections containing intraocular melanomas, and solve complex equations including statistical analysis. The results showed that over 150 different ophthalmologists contributed specimens to this data base. The mean age of the patients studied was 57 years and the tumors were evenly distributed according to sex and laterality of the eye. This study illustrates the feasibility of using a low-cost microcomputer and commercially available software in the study of a large patient data base.
