ABSTRACT To relate a case not described previously in the national multilateral ophthalmological literature of Descemet’s membrane. A 59-year-old pseudophakic woman diagnosed with bullous keratopathy underwent penetrating keratoplasty with an unusual finding of multiple layers of Descemet’s membrane, which were variable in shape and thickness. In addition, ovoid bodies with negative Gocott-Gomori (GMS) color were present. Discussion and Conclusion: As Descemet’s membrane has a fetal and a postnatal period in its development, it is frequently and well identifiable in histological […]

We report an unusual case of a 65-year old patient that developed localized bilateral Descemet membrane detachment during non-simultaneous femtosecond laser-assisted cataract surgery (FLACS). The detachment occurred when the laser was performing the secondary incision. In the operating room, the isolate-and-release technique was used to effectively manage this complication. To the best of our knowledge, this is the first reported case of bilateral Descemet membrane detachment during FLACS.

Objetivo: Encontrar fatores importantes na patogenia do edema corneano pós-cirúrgico, em casos de pós-facectomia e pósceratoplastia, por meio do estudo dos achados histopatológicos, a fim de ver o que pode ser feito para evitar sucessivas ceratoplastias. Métodos: Estudo retrospectivo descritivo das alterações histopatológicas de casos de edema corneano pós-cirúrgicos. Os tecidos foram provenientes de ceratoplastia penetrante no período compreendido entre setembro de 2009 e agosto de 2013. Foi realizada revisão de prontuários em busca principalmente de informações sobre cirurgias prévias. […]

The detachment of Descemet’s membrane can be a serious complication following cataract surgery, leading to severe corneal edema and reduced visual acuity. This report describes an unusual case of Descemet’s membrane detachment 6 months after successful phacoemulsification, documented by anterior segment optic coherence tomography (OCT; RTVue, Optovue). The eye was treated successfully with pneumatic descemetopexy and transcorneal suturing, with reattachment of Descemet’s membrane. This report should alert physicians that delayed corneal edema can be related to late-onset Descemet’s membrane detachment, […]

PURPOSE: To evaluate by high frequency ultrasound biomicroscopy (UBM) the anatomical characteristics of viscocanalostomy and their relationship with the intraocular pressure (IOP) lowering. METHODS: A transversal study which included 9 eyes (7 patients) undergoing viscocanalostomy and examined by high frequency UBM (80 MHz). Several UBM variables were evaluated, including the presence of the intrascleral space, the maximum length and height of the intrascleral space and the minimum thickness of residual trabeculo-Descemet membrane (TDM). Surgical success was considered to be achieved […]

PURPOSE: Evaluate the effect of micro puncture with radiofrequency as treatment of symptomatic patients with bullous keratopathy. METHODS: Prospective study in 10 pacients with syntomatic bullous keratopathy and low vision. Micro puncture with radiofrequency was made in areas of the anterior stromal that had an epithelial descompensation. The evaluation of the patients was realized trough clinical examinations (biomicroscopy, pachymetry, tonometry and esthesiometry) and symptom graduation (pain intensity, foreign body sensation, photophobia and insomnia caused by pain). RESULTS: The comparisons of […]
