Nontraumatic ghost cell glaucoma--a case report.

Ghost cell glaucoma (GCG) has recently been described following vitrectomy, cataract extraction, and penetrating or blunt trauma. We describe the occurrence of GCG in a phakic eye with no prior ocular trauma or surgery following vitreous hemorrhage from diabetic retinopathy. We postulate the occurrence of a spontaneous rupture of the anterior hyaloid face which allowed passage of ghost cells into the anterior chamber. A therapeutic vitrectomy was complicated by intraoperative vitreous hemorrhage. Two weeks postvitrectomy, GCG recurred and was successfully controlled by irrigation through an anterior chamber approach. This is the procedure of choice in GCG following vitrectomy and may eliminate the need for a second vitrectomy.

Momentary fluctuations of intraocular pressure in normal and glaucomatous eyes.

To examine the range of momentary fluctuations of intraocular pressure caused by vascular pulsations in 42 glaucomatous and 18 normal eyes, we obtained consecutive intraocular pressure measurements at hourly intervals with a noncontact air tonometer. Glaucomatous eyes had a significantly (P less than .001) greater range of intraocular pressure measurements on consecutive readings than normal eyes (4.4 +/- 1.4 mm Hg vs 2.7 +/- 0.7 mm Hg). The frequency of consecutive intraocular pressure readings exceeding a spread of 4 mm Hg was significantly increased in glaucomatous eyes. The range of intraocular pressure measurements was greater even in those glaucomatous eyes with mean intraocular pressures within the normal range. There was a positive correlation between mean intraocular pressure and mean range in glaucomatous eyes, but not in normal eyes. In both glaucomatous and normal eyes, there was no significant correlation between age and mean range.
