Hypotonus cyclodialysis cleft following suture fixation of a posterior chamber intraocular lens [Case Report]

Small EA; Solomon JM; Prince AM
A 63-year-old man developed hypotony due to a cyclodialysis cleft after suture fixation of a posterior chamber intraocular lens. Since medical management and argon laser photocoagulation were unsuccessful, a direct cyclopexy was performed. The intraocular pressure returned to normal postoperatively, and gonioscopy confirmed closure of the cleft. To our knowledge, this is the first case report of cyclodialysis complicating ciliary sulcus fixation of a posterior chamber lens

Chimpanzees and AIDS research

Prince, A M; Moor-Jankowski, J; Eichberg, J W; Schellekens, H; Mauler, R F; Girard, M; Goodall, J
Pressure is mounting to relax the regulations on importation of chimpanzees for research. Such a policy is unnecessary and would deepen the plight of an already endangered species

Pseudoexfoliative fibrillopathy in the conjunctiva. A relation to elastic fibers and elastosis

Streeten BW; Bookman L; Ritch R; Prince AM; Dark AJ
Pseudoexfoliative (PSX) material in the conjunctiva was found to have a close association with elements of the elastic system in 13 eyes of patients with PSX disease studied ultrastructurally. Pseudoexfoliation aggregates were rare within vascular walls but frequent in proximity to the plasmalemma of stromal fibroblasts. No amyloid was found. A striking feature was the association of PSX fibers with the elastosis seen in many of the specimens. Typical PSX fibers were present in clumps of oxytalan and around small elastic fibers. In five cases with more advanced elastosis, the aggregates of PSX fibers were larger and their usual loose fibrogranular matrix was extensively replaced by a dense elastotic one. Morphology of PSX here varied from typical to thicker, fragmented, and sometimes nondiagnostic fibers. This intermingling of PSX and elastotic materials suggested that PSX fibrillopathy is itself a type of elastosis, possibly resulting from abnormal aggregation of components related to elastic microfibrils

Preclinical diagnosis of pseudoexfoliation syndrome

Prince AM; Streeten BW; Ritch R; Dark AJ; Sperling M
Although the diagnosis of pseudoexfoliation syndrome (PXS) is made by observation of pseudoexfoliation material (PXM) deposited on the anterior lens capsule, there are several additional signs related to pigment dispersion that are often present both in eyes with PXS and fellow eyes in unilateral cases. On the basis of the presence of these signs, we have categorized a group of patients as 'pseudoexfoliation suspects' who demonstrated no evidence of PXM on the lens capsule in either eye. As PXM has previously been identified in the conjunctiva of affected eyes as well as fellow eyes in unilateral cases, we hypothesized that it could also be present in PXS suspect eyes. Inferior bulbar conjunctival biopsies were performed on four eyes with PXS, five fellow eyes, and 23 PXS suspect eyes, and specimens were examined by transmission electron microscopy. In eight PXS suspect eyes biopsy specimens demonstrated PXM, suggesting that PXS is more prevalent and possibly responsible for a greater proportion of glaucoma than previously suspected

Clinical signs of the pseudoexfoliation syndrome

Prince AM; Ritch R
Pseudoexfoliation syndrome (PXS) is a common cause of glaucoma throughout the world. It is most commonly diagnosed after the observation of pseudoexfoliation material (PXM) on the anterior lens surface. However, there are numerous clinical signs of PXS that should alert the examiner to search carefully for PXM on the anterior lens surface. These include pupillary ruff defects, iris sphincter transillumination, a characteristic whorl-like pattern of particulate pigment deposition on the iris sphincter, particulate pigment deposition on the peripheral iris and trabecular meshwork, and exfoliation material on the zonules and ciliary body. Accuracy of diagnosis is important for purposes of treatment, prognosis, and basic research in he mechanisms of glaucoma, particularly tissue culture
