Comparative study of hyperacuity and retinometer tests for the evaluation of vision in patients with advanced cataract.

OBJECTIVE: To investigates the clinical application value of hyperacuity test for evaluating vision through dense cataracts. METHODS: Ten normal subjects (20 years) were tested both with Bailey-Lovie type chart and three points vernier acuity test (one of the hyperacuity test); and retinometer test were performed preoperatively and postoperatively in 30 patients (31 eyes) with senile cataract. These patients' lens opacity was classified with LOCS III system. RESULTS: The correlation of vernier acuity and visual acuity of normal subjects is significant. The result of difference compression of pre-surgical and post-surgical vernier acuity of 30 cataract patients is not significant. The correlation of retinometer findings with post-surgical visual acuity shows not statistically significant. Our result shows that there is good correlation between vernier acuity and post-surgical visual acuity. CONCLUSION: It appears that hyperacuity is a good test for foveal function behind dense cataract and other ocular opacities.

Epithelial downgrowth.

We present a surgically treated case of epithelial downgrowth with clinicopathologic correlation and special emphasis on the ultrastructural findings. Long-term follow-up revealed a salvaged eye, but with only peripheral vision due to glaucomatous optic atrophy.

The onset of anorexia nervosa.

In a retrospective study of case notes a number of experiential and psychological factors were discerned of possible importance to the psychogenesis of anorexia nervosa. These factors included issues of dependence and independence, sexual challenge, concern about obesity, and a variety of other, less specific stresses. Attempts to confirm the findings by means of a prospective study were impeded by difficulties in defining the onset of the illness. While in some patients the occurrence of anorexic type behaviour led immediately to weight loss, in others there was a significant delay between the onset of behavioural change and consequent emaciation.
