All these eyes were proven refractory to maximal medical therapy for extended periods of time, in some cases more than 6 weeks. As the surgery was performed during the active stage, the outcome was not favorable functionally. Clinical cure was obtained, however, by therapeutic penetrating keratoplasty in all but 27 of these eyes. Of unsuccessful cases, 16 could be saved with additional medical therapy, two led to phthisis bulbi, and nine required repeat therapeutic penetrating keratoplasty. Complications encountered included disturbances in intraocular dynamics such as extrusion of the lens and vitreous during surgery, secondary rise of intraocular pressure leading to damage of the optic nerve, loss of the eye due to above factors, and reinfection. The anatomical success achieved was 97% with graft clarity of 2+ or more in 39% of eyes. Useful vision, ie, better than or equal to 6/60, was possible in 33% of eyes. Thus, therapeutic keratoplasty in refractory corneal ulcer still has scope in a Third-World country.</p>","PeriodicalId":19625,"journal":{"name":"Ophthalmic surgery","volume":"26 4","pages":"325-9"},"PeriodicalIF":0.0,"publicationDate":"1995-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"19512089","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Cadaver eyes, however, have been of only limited utility for teaching highly complicated procedures because of the obscuring of intraocular structures caused by the rapid post mortem onset of corneal swelling. We have overcome this problem by the use of a silicone keratoprosthesis that provides an excellent view of all intraocular tissues.

It thus can reduce the rate of complications in operations on patients.</p>","PeriodicalId":19625,"journal":{"name":"Ophthalmic surgery","volume":"26 4","pages":"358-9"},"PeriodicalIF":0.0,"publicationDate":"1995-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"19512093","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We evaluated the surgical outcome of 60 eyes with either primary open-angle glaucoma or pseudoexfoliation syndrome that underwent combined trabeculotomy ab externo and cataract extraction. All patients were at least 40 years old, and were followed for at least 1 year. At the final examination, IOP was well controlled (21 mm Hg or less) in 54 (90%) of the 60 eyes, with or without medication. Also, \"overall success\" (ie, stabilization of IOP, visual field, and optic nerve status) was achieved in 49 (81.7%). Complications included fibrin exudation (22%), transient IOP elevation (17%), early perforation of the probe into the anterior chamber (10%), and detachment of Descemet's membrane (5%). We recommend combined trabeculotomy ab externo and cataract extraction in selected cases of glaucoma with coexisting cataract. For cases in which the target IOP level is in the low teens, or for patients who may not tolerate postoperative fluctuations in IOP, we do not recommend trabeculotomy ab externo. Also, in eyes that have normal-tension glaucoma, or that have already sustained severe damage to the optic nerve, visual dysfunction caused by glaucomatous changes may progress even after successful combined trabeculotomy ab externo and cataract extraction.","PeriodicalId":19625,"journal":{"name":"Ophthalmic surgery","volume":"38 1","pages":"316-24"},"PeriodicalIF":0.0,"publicationDate":"1995-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88868139","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Such a procedure prevents undesirable enlargement of the sclerotomy induced by trauma to the wound caused by instruments that can occur in cases of previously damaged sclera or in thin sclera associated with high myopia. It also prevents leaks through the wound as instruments are withdrawn.","PeriodicalId":19625,"journal":{"name":"Ophthalmic surgery","volume":"8 1","pages":"360-1"},"PeriodicalIF":0.0,"publicationDate":"1995-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87168466","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
