Enhanced visualization of capsulorhexis with indocyanine green staining in pediatric white cataracts.
PURPOSE: To evaluate the enhancement of the visualization of the anterior lens capsule with indocyanine green (ICG) in pediatric dense, mature cataracts. PATIENTS AND METHODS: Six children (10 eyes) 4 to 9 years old with complete, white cataracts underwent ICG-enhanced cataract surgery. RESULTS: All of the eyes showed a complete continuous curvilinear capsulorhexis and a well-centered intracapsular implant. No surgical or postoperative complications were encountered. CONCLUSION: Staining the anterior capsule with ICG is an excellent way to facilitate performance of an anterior capsulorhexis in pediatric white cataracts.
Vitreous hemorrhage as the initial manifestation of X-linked retinoschisis in a 9-month-old infant.
A 9-month-old infant presented with progressive esotropia, bilateral vitreous hemorrhages, bullous retinoschises, and peripheral retinal detachments. X-linked retinoschisis was diagnosed on the basis of electroretinogram findings. We report a case of vitreous hemorrhage as the initial presentation of X-linked retinoschisis in one of the youngest patients discussed in the literature.
A comparison of the effectiveness of four biostains in enhancing visualization of the vitreous.
PURPOSE: To compare the effectiveness of four biostains in vitreous staining as a means to facilitate clean anterior vitrectomy. MATERIALS AND METHODS: Four biostains (fluorescein, indocyanine green, trypan blue, and triamcinolone acetonide) were used to stain the transparent vitreous of human cadaver and monkey cadaver eyes. Results were compared and recorded by digital photography and videography. RESULTS: Of the four biostains, triamcinolone acetonide best highlighted the vitreous. Although fluorescein, indocyanine green, and trypan blue also produced acceptable vitreous staining, the surrounding ocular structures were slightly stained as well. CONCLUSION: All four biostains enhanced visualization of the vitreous. However, triamcinolone acetonide best highlighted the vitreous.
