Retinitis pigmentosa associated with glaucoma--clinical analysis.
A clinical analysis of Retinitis Pigmentosa (RP) was made in 2,789 eyes of 1,400 patients seen over a 5 year period (1983-1987), 64 eyes of 32 cases (2.3%) of RP associated with glaucoma were investigated. Of these 32 cases, the angle closure glaucoma was much more than the open angle glaucoma (30/2). More than half of the 32 cases were without cupping of disk, 5 cases did not have the glaucomatous damage to disk in spite of persistent elevated intraocular pressure for 0.5-5 yrs under the maximum medical therapy. 31 cases (97%) had subnormal blood pressure compared with the normal blood pressure value in different age groups. Histopathologic changes of the trabecular meshwork (TM) of 14 eyes showed a little bit more pigment cells in the TM than normal subjects, no typical features that would obstruct the outflow channels.
