To observe the short-term changes in morphology of Elschnig pearls induced by Nd:YAG capsulotomy. ⋯ Capsulotomy had an immediate impact on the morphology of PCO outside the capsulotomy opening, probably due to the direct mechanical impact of the laser shockwave.

Evidence of a link between Alzheimer's disease (AD) and glaucoma has emerged from studies showing that patients with AD may have a significantly increased rate of glaucoma occurrence. In addition, it has been reported that patients with AD exhibit optic nerve degeneration and loss of retinal ganglion cells. In spite of intensive research, the clinical and genetic relationships between AD and glaucoma remain obscure. ⋯ It was noted that this observation supports the concept that an abnormal high trans-lamina cribrosa pressure difference, whether the result of elevated intraocular pressure, reduced CSFP, or both, plays an important role in glaucomatous optic nerve damage. Interestingly, it was also reported that a substantial proportion of AD patients have very low CSFP. Therefore, we hypothesise that an abnormal high trans-lamina cribrosa pressure difference may explain why patients with AD have a greater risk for developing glaucoma.
