Clinical agreement among glaucoma experts in the detection of glaucomatous changes of the optic disk using simultaneous stereoscopic photographs

PURPOSE: To evaluate the clinical agreement in the detection of optic disk changes in patients with glaucoma using simultaneous stereophotographs. DESIGN: Masked-observer variability study. METHODS: Ten glaucoma specialists examined pairs of simultaneous stereophotographs of glaucomatous and control optic disks to determine whether there were changes compatible with progression of glaucomatous damage. RESULTS: Intraobserver agreement had a kappa value ranging from 0.55 to 0.78. Interobserver agreement among the glaucoma specialists had a kappa value ranging from 0.34 to 0.68. CONCLUSION: Clinical examination of stereophotographs to detect optic disk changes in glaucoma patients has limitations associated with suboptimal reproducibility. © 2003 by Elsevier Inc.

Reflection of Qualitative Methods: “memoring” fieldwork experience in organisational research with photographs

The paper is a reflection on the use of photographs in multiple case study research. It explores the crossovers between interpreting visual artefacts, the qualitative approach to case study research in organisations, and the move from cases to theory guided by the grounded theory tenets. The paper proposes an additional use of photographs as a visual method to those in the literature, as a device for data analysis. Photograph-based analysis techniques are explored, using e sequence of individual images and photo collages on case data, moving from interpretation of single to multiple case themes. This makes the case of using photograph analysis as an interpretation device for case research to illuminate theory development.

Photographs of secretarial staff at Lightning Fastener, ca. 1935

Lightning Fastener Co. Ltd. was a zipper manufacturer located on Niagara Street in St. Catharines. It was founded by Gideon Sundback, the inventor of the modern fastener. Sundback was born in Sweden, but settled in the United States in 1905. It was here that he designed and patented a “separable fastener” in 1913. Although he lived in Hoboken, New Jersey, he decided to establish a manufacturing facility for his invention in Canada, choosing St. Catharines over other locations such as Fort Erie and Hamilton. At the height of its success, the company employed more than 500 people and produced more than 50 million zippers annually. Over time, the company had difficulty remaining competitive and was forced to close in 1981.
