Abstract

Epinephrine maculopathy is a reversible macular change that occurs in aphakic eyes being treated with topical epinephrine compounds. The first symptom is transient blurred vision, which can be followed by decreased visual acuity, flame-shaped hemorrhages, and cystoid macular edema. Onset of symptoms can range from a few days after the commencement of epinephrine therapy to several months thereafter. Epinephrine maculopathy should be differentiated from Irvine-Gass syndrome. Treatment consists of changing the patient's therapeutic regimen for glaucoma to other pharmaceutical agents. When this is done recovery of pre-maculopathy visual acuity and reversal of cystic macular changes usually occur.

[Sandwich intraocular lens implant: a concept for aphakia correction in children].

BACKGROUND: In the management of congenital cataracts the correction of aphakia is still an unsatisfactorily solved problem. As far as surgical techniques and materials are concerned, the implantation of an IOL seems to be justified even in younger children; but choosing the refractive power of the lens is somewhat difficult regarding the expected growth of the eye. MATERIALS AND METHODS: A new type of IOL is presented as a solution for this problem. Being composed of a PMMA-fashioned optic and haptic it bears a silicone lens which is fastened on top of it. The supporting lens is made of PMMA (polymethylmethacrylate) with a biconvex surface with modified J-loops. The diameter of the optic is 6 mm, the overall diameter is 11 mm. The supplementary lens is made of the same silicone material as used for foldable intraocular lenses. Its diameter is 4.5 mm. This additional component can be removed from the implanted lens so that the needed reduction of refractive power after completed growth of the eye can be performed. The PMMA-fashioned basic component remains in situ just like a conventional posterior chamber lens. The lens was examined using scanning-electron microscopy. Im- and explantation was performed in isolated porcine eyes. RESULTS: The high quality of the lens could be demonstrated using scanning-electron microscopy. The technical feasibility of this concept could be demonstrated on isolated porcine eyes. DISCUSSION: Currently the sandwich lens is being tested in animal experiments. Our special interest is focussed on biocompatibility, formation of secondary cataract, biological reactions in the interface and the possibility of atraumatic explantation of the silicone lens.
