A rare case of delamination and replication of the anterior lens capsule into prominent floating folds in the anterior chamber approximately 55 years after a penetrating injury to the eye and anterior lens capsule is reported. Classically, true exfoliation of the anterior lens capsule has been reported in individuals who have been exposed to intense heat over a prolonged period. However, more r...

Exfoliation of graphite is a promising approach for large-scale production of graphene. Oxidation of graphite effectively facilitates the exfoliation process, yet necessitates several lengthy washing and reduction processes to convert the exfoliated graphite oxide (graphene oxide, GO) to reduced graphene oxide (RGO). Although filtration, centrifugation and dialysis have been frequently used in ...

Isolating large-areas of atomically thin transition metal chalcogenide crystals is an important but challenging task. The mechanical exfoliation technique can provide single layers of the highest structural quality, enabling to study their pristine properties and ultimate device performance. However, a major drawback of the technique is the low yield and small (typically < 10 μm) lateral size o...

The condition of pseudoexfoliation of the lens capsule seems common in some racial groups, and a high incidence of the condition has been reported in Scandinavia (Ladekarl, I965; Hansen and Sellevold, I968; Klouman, I967; Thomassen, I949; Backhaus and Lorentzen, I966; Horven, i966a), and in Greece (Joannides, Katsourakis, and Velissaropoulos, I96i). This raises the question whether pseudoexfoli...

The aim of the study was to evaluate the efficacy of replacing current dual local therapy (timolol and pilocarpine) with latanoprost 0.005% in 71 pseudoexfoliation glaucoma patients with controlled intraocular pressure (IOP). 39 patients switched to latanoprost 0.005%) and 32 patients continued timolol-pilocarpine therapy. Mean diurnal (IOP) was measured at baseline, after 0.5, 1, 3 and 6 month...

Crystalline lens dislocation and zonular dialysis during intraocular surgery are recognised features of the pseudoexfoliation syndrome (PES). A case is reported in which zonular dialysis occurred in both eyes during extracapsular cataract extraction. In particular surgery was complicated by difficulty in performing anterior capsulotomy. Careful preoperative assessment and peroperative technique...

&gl~$g. Anterior segment perfusion povides a tool for determining flow in the trabecular outflow pathway only, contrary to perfusion of whole eyes in which 10-3046 of the outflow comes on account of the uveoscleral pathway. Since disposed human eyes are not abundantly available, especially not as a pair, it would be convenient to develop a model in which one half of an anterior segment could se...

PURPOSE To present early-onset ocular manifestations of pseudoexfoliation syndrome in young patients who had undergone multiple intraocular procedures. METHODS This is an observational case series, introducing four cases with histories of multiple intraocular procedures for glaucoma. RESULTS All reported cases demonstrated typical manifestations of pseudoexfoliation unilaterally in the eye ...
