Comparison of photo slit lamp and fundus camera photography of the optic disc.

The photo slit lamp has characteristics that may be important in optic disc photography for measuring glaucomatous cupping. This finding led to the question of whether disc photographs with the slit lamp showed less detail than fundus camera photographs. Tests were conducted on in-air resolution and of each instrument's ability to record fine vessel detail in normal human optic discs. The results showed that the instruments performed comparably in each test.

Broken nylon iris fixation sutures.

Broken nylon iris sutures, used to fixate the Worst suture lens, occurred in 41 of a series of 215 eyes, a remarkably high frequency. The estimated average time to break was 27.8 months. Over three fourths of the borken sutures were discovered incidentally on a return visit. Complications related to the broken suture occurred in 21 eyes. The characteristic complication was corneal epithelial edema caused by intermittent touch of the endothelium by the broken suture; spontaneous lens dislocation was infrequent. Light and scanning electron microscopy revealed that biodegradation caused the suture break. Broken iris sutures can be avoided by fixation of the lens with a nonbiodegradable suture.
