Abstract
Whether a family history of glaucoma (FHG) in patients with pigmentary glaucoma (PG) is a prognostical indicator, is unknown. Therefore the aim of this study was to evaluate the influence of FHG on the severity of the disease in PG and pigment dispersion syndrome (PDS). Furthermore risk factors in PG and PDS were evaluated. The findings of 207 patients with PG and PDS, who were able to give information about FHG, were evaluated (149 PG, 43 PDS with ocular hypertension (OH), 15 PDS without OH). Significance of FHG: FHG was found in 39.1%, and in one third of the patients more than one relative had the disease. FHG was found in PG not more frequent than in PDS. Pigmentary glaucomas in advanced stages of the disease did not have a higher incidence of FHG than patients in beginning stages. Out of 207 patients with PG and PDS 71% were male and 29% female (p < 0.001). In patients with FHG the share of men was 64.2% and not significantly different to the group without FHG with 75.4%. The sex distribution in parents and grandparents having a glaucomatous disease was 1:1. The pf1p4nts with and without FHG in PDS with and without OH, PG, and within the different stages of visual field loss, showed no significant differences in risk factors, for example in maximum intraocular pressure, refraction and cup-disc ratio. Myopia: Patients with PG had a significantly higher myopia than patients with PDS (p < 0.01). The higher the myopia, the earlier the disease was diagnosed (p = 0.008). Krukenberg spindle: During miotic therapy the Krukenberg spindle decreased in the upper half of the cornea. Time of diagnosis: PG was diagnosed at a higher age compared to PDS. FHG does not influence the severity of the disease in PG. Family history of glaucoma is a risk factor in patients with PG, but no prognostical indicator. Patients with FHG do not have primarily larger cup-disc ratios than patients without FHG. Myopia is a risk factor.
