“…Caprioli reported that the ACs of patients with PDS were deeper than those with primary open angle glaucoma (POAG) when corrected for age and refraction 26 . The ACs of eyes with PDS appear deepest at 3.5 mm below axis 27 , and in asymmetric cases the ACs were deeper in the most affected eye, suggesting that deep ACs have a role in the pathogenesis 28,29 .

Pigment dispersion syndrome (PDS) is an interesting condition that can lead to secondary open angle glaucoma. Pigmentary glaucoma is primarily a disease of young people, myopes and men. PDS is characterized by the presence of Krukenberg spindles, iris trans-illumination defects, trabecular meshwork pigmentation and backward bowing of the iris. Posterior bowing of the iris causes rubbing of the pigmented iris epithelium against lens structures, liberation of pigment and trabecular meshwork changes that result in reduced aqueous outflow with the risk of glaucoma. Peripheral laser iridotomy can reverse backward bowing of the iris and may prevent progression of pigmentary glaucoma.

“…In PDS and pigmentary glaucoma, it has been hypothesized that pigment is sloughed from the posterior iris surface by lens zonules that rub against the iridial tissue. 1,37,38 Structural abnormalities of the middle third of the eye have been noted in PDS. The size of the iris appears to be overly large relative to that of the anterior segment.…”

Objective: To assess aqueous humor dynamics in pigment dispersion syndrome (PDS). Methods: Four groups of age-matched participants included 2 experimental groups with PDS (PDS with ocular hypertension [PDS-OHT], 17 eyes; PDS without ocular hypertension [PDS-ONT], 18 eyes) and 2 control groups without PDS (OHT, 18 eyes; ONT, 18 eyes). Assessments included intraocular pressure measured by pneumatonometry, episcleral venous pressure by venomanometry, aqueous flow and outflow facility by fluorophotometry, corneal thickness and anterior chamber depth by pachymetry, and uveoscleral outflow by mathematical calculation. Comparisons were made by analysis of variance and 2-tailed unpaired t tests. Results: The PDS-OHT group had higher intraocular pressures than the ONT and PDS-ONT groups (PϽ.001) and higher episcleral venous pressure (P=.04) and lower outflow facility (P=.01) than the ONT group. Anterior chamber volume was larger in the PDS-OHT group than in the other groups (PϽ .05 for all). No other comparisons between the PDS-OHT group and the other groups yielded statistically significant differences at a significance level of less than .05. Conclusions: The elevated intraocular pressure in PDS is caused by reduced outflow facility. This differs from OHT without PDS, in which reductions in uveoscleral outflow and outflow facility have been reported.
