[Factors determining the occurrence of intraocular hypertension in uveitis]

Thirty-two acute hypertensive unilateral, non granulomatous uveitis were clinically and functionally examined to try to determine the pathogenic factors of the occurrence of intraocular hypertension. The witness group included an equal number of acute non-hypertensive, non-granulomatous and unilateral uveitis cases, with a clinical aspect and etiology similar to the first group. The determination of the coefficient of outflow facility to the patients with hypertensive unilateral uveitis emphasized pathological values in 93.7% of the eyes with uveal inflammation and in 56.2% of the fellow eyes. Gonioscopy in the fellow eyes disclosed a narrow indocorneal angle in 90.6% of the cases. Corroboration of fellow eyes, all the examinations of the emphasized 4 had history cases of simple glaucoma (of which 2 had a familial of primitive glaucoma) and 6 cases of suspicious glaucoma (of which 4 had a familial history of primitive glaucoma). The patients with non-hypertensive unilateral uveitis presented normal values of the outflow facility in the two eyes. Clinically and functionally their fellow eyes were normal. Taking into account the statistically significant difference between the mean age of uveitis with and without hypertension, it is concluded that advanced age represents indirectly a factor of hypertension in uveitis, because, since, it diminishes the degree of opening of the camerular angle and as well, it reduces the outflow facility and increases the frequency of occurrence of simple and suspicious glaucomas.
