[A study on retinal light sensitivity of normal human visual fields].

The full threshold program of QZS-2 automated perimetry made in China was used to measure the retinal light sensitivity of the central 30 degrees and peripheral 30 degrees-60 degrees visual fields of 111 eyes of 59 normal persons. Their ages ranged from 15-68 years and the average age was 38.4 years. From the corresponding respective comparisons of the results, it is shown that the mean light sensitivity of the macular, central 30 degrees and peripheral 30 degrees-60 degrees visual fields between the left and right eyes has no statistical significant differences (P > 0.05), and there are also no statistical significant differences (P > 0.05) in the mean light sensitivity of the central and peripheral fields between the male and female subjects. The mean light sensitivity declines linearly with the increase of age and eccentricity. The mean light sensitivity of the central and peripheral visual fields decreases 0.6 dB and 0.7 dB, respectively, with each one decade increase of age. The mean light sensitivity also decreases by 2.6 dB per 10 degrees eccentricity. The mean short-term fluctuation in the normal subjects is 1.39 +/- 0.56 dB.

[A randomized controlled study of the anti-cicatricial effect of preoperative subconjunctival triamcinolone on the filtering bleb].

A randomized controlled study of the anticicatricial effect of preoperative subconjunctival triamcinolone acetonide (TA) on the filtering bleb in 89 eyes (61 cases) of refractory glaucoma showed that the rates of surgical success in the TA groups were 77.3-89.0% and that in the control group 48.0%. The varying dosages of TA produced insignificant differences; however, the proportional distribution of the types of filtering blebs differed significantly among the various dosage groups, and complications occurred mostly in the high dosage group of 12 mg. The study indicated that TA raised the surgical efficacy in treating refractory glaucoma and the dosages of choice were 4-8mg.

[The exfoliation or pseudo-exfoliation syndrome].

The exfoliation or pseudo-exfoliation syndrome (PE) is very rare in China. The clinical and histopathologic features in 13 patients were that the loss of pigment at the pupillary ruff and dense pigmentation on the trabecular meshwork were early signs easily overlooked, and the dandruff-like particles at the pupillary margin and greyish white ring at the anterior periphery of the lens were typical findings. Histopathologic study demonstrated that the PAS-positive amorphous material under light microscopy were fibrils in structure and accumulated at various sites in the anterior segment of the eye.

Pseudoexfoliation syndrome in Chinese.

The exfoliation syndrome is thought to be a very rare disease in China. The clinical features of 11 patients with pseudoexfoliation (PE) and the histopathologic changes in specimens affected by PE were studied. The loss of pigment at the pupillary ruff and the dense pigmentation on the trabecular meshwork were the early signs in the PE patients. Light and electron microscopic studies demonstrated that the PE materials were deposited on multiple sites in the anterior segment of the eye. To the best of the authors' knowledge, this is the first paper on the PE syndrome from China.
