ABSTRACT.Background: The management of traumatic optic neuropathy remains controversial. This retrospective study presents the results of 19 cases of indirect optic neuropathy where surgical decompression represented the primary mode of treatment. Methods: Nineteen patients (20 optic nerves) with traumatic optic neuropathy underwent primary surgical decompression. The surgery was performed using the transethmoidal technique. Results: The extent of bony optic canal injury documented during surgery indicated that this had been underestimated in this series by CT findings. Vision improved in eight patients, five of whom had had no light perception preoperatively. Conclusion: Primary surgical decompression of the optic nerve within 48 h of injury produces beneficial results. Testing of visual acuity 6 weeks after surgery does not serve as a reliable predictor of final outcome.

Purpose: Age-corrected values are indispensable in assessing discrete changes in light difference sensitivity (LDS) when evaluating perimetric results. In order to detect incipient visual field defects, the present study aimed particularly to determine function of normal values depending on age and eccentricity. Methods: A test group (n = 83) of ophthalmologically and clinically unremarkable subjects 18–74 years of age was examined with the ‘Centerfield’ perimeter. A brief introductory program was first used to familiarize each test person with the situation. Then values in the central visual field (30Results: Age-related normal values were calculated both as group averages and as lines of regression by statistical analysis of the resulting data. In contrast to other perimetric studies, decreases in LDS at different test points for persons aged 20 years to persons over 60 were not linear. Conclusions: Age-related normal values should be reviewed for other perimeters.

Allogen cartilage grafts to a clear corneal pounch do not induce an inflammatory reaction. Therefore, autologous cartilage prepared of ears seems to be useful biological material in ophthalmologic surgical procedures, for example to fill up corneal defects. To investigate if cartilage grafts will be helpful to stop neovascularisation in keratoplasty further studies with vascularisized corneas are necessary.
