The hypothesis that ocular pseudo-exfoliation syndrome is part of a generalized disorder has been tested by suggesting that subjects having this syndrome would have increased mortality. However, no association was found between presence of ocular pseudo-exfoliation syndrome and mortality.

On the basis of a glaucoma survey in a total population greater than or equal to 65 years of age, the IOP in eyes with and without pseudo-exfoliation (PE) has been compared. The average IOP was 22.2 mmHg in eyes with PE versus 17.4 in eyes without. The corresponding averages in eyes without glaucomatous damage were 18.6 and 17.1 mmHg, and in eyes with glaucoma 31.5 and 25.5 mmHg. The IOP elevation connected with the PE process was 4.8, 1.5, and 6.0 mmHg in the total, normal and glaucomatous population, respectively. The IOP frequency distribution curves of these 3 groups were compared. The right shift of the distribution curves of the PE groups was more pronounced at high pressure levels. The PE process seems to elevate the IOP particularly in eyes with a high IOP, which is in correspondence with hydrodynamical laws. At a certain IOP, the probability of having glaucomatous damage was higher in eyes with PE than in those without, indicating an increased vulnerability of PE eyes to an elevated IOP. PE may be a glaucoma risk factor also on its own, i.e. independent of the pressure elevation connected with this syndrome.

200 good readers and 41 poor readers selected from 718 pupils in a primary school, grade 1-6 were examined in respect of stereopsis, visual acuity, phorias, tropias, fusional breakpoint, fusional amplitude and objective refraction. No statistical difference was found between the 2 reader groups, and the need for optical aid was of the same order. 80 of the 241 children had unnecessary glasses, and many of those who needed spectacles were improperly aided.
