[The effect of lens haptics on postoperative anterior chamber depth in PMMA posterior chamber lenses].

In two groups of patients with two different posterior chamber intraocular lenses, very different correlations were found between postoperative and calculated anterior chamber depth, and between postoperative anterior chamber depth and axial length. Since it has long been known that there are positive correlations between anterior chamber depth and axial length in phakic patients, while on the other hand (according to many authors) these correlations seem to disappear in pseudophakic patients, and since the present authors found these positive correlations only in patients with one type of implant, they ascribe these differences between similar implants to the geometric configurations of the lens loops. In lenses with modified J-loop designs the optical zone might be dislocated backward when the lens is compressed, while lenses with C-shaped seem to suffer only minimal dislocation or none at all.

[Contributions to the Aulhorn flicker test. II: The flicker test and the Pulfrich phenomenon in clinical diagnosis].

Fourteen patients with symptoms of acute unilateral optic neuritis were examined with the Pulfrich test and the Aulhorn flicker test. It was found that the positive Pulfrich response and the depth of the apparent orbit depends on the ocular or neural diseases causing a difference in neural conduction from the two eyes. The Pulfrich test is positive for considerably longer than the flicker test.

[The Aulhorn flicker test. I: Concomitant neuritis in malignant non-Hodgkin's lymphoma and leukodystrophy].

Cases of optic nerve involvement in malignant non-Hodgkin lymphoma and multifocal progressive leukodystrophy are reported. In both patients an optic neuropathy was diagnosed secondary to infiltration of the optic nerve and the Aulhorn flicker test was positive. Pathological and neurophysiological conditions which yield a positive flicker test are discussed in the light of these findings.

[Perforating eye injuries caused by darts].

Four perforating eye injuries sustained by children playing with darts are analyzed. The injuries occurred within a period of 17 months. All the patients had minor injuries of the anterior segment and severe injuries in the posterior segment, such as vitreous hemorrhages and double perforations.

[Correction of unilateral aphakia in children, adolescents, and adults at an age when accommodation is still possible].

Twenty-one patients, aged 4-42 years, with unilateral aphakia after perforating injury, were corrected with a combination of spectacles and contact lenses. While taking stereopsis and aniseikonia into consideration, each patient was corrected with the combination of contact lens and spectacles to achieve the best stereoscopic vision. Two of the five children (aged 4 and 7) achieved positive results on stereoscopic acuity.
