1/4. Loss of iridolenticular contact in eyes with exfoliation syndrome may protect against glaucoma.PURPOSE: To provide evidence for the hypothesis that dynamic iridolenticular contact predisposes to the development of glaucoma in exfoliation syndrome (XFS). methods: We present four patients with bilateral XFS and unilateral exfoliation glaucoma (XFG) whose normotensive eyes had suffered traumatic loss of dynamic iridolenticular contact. RESULTS: All 4 patients had bilateral XFS and developed XFG only in the untraumatized eyes. One patient had loss of iridolenticular contact in the traumatized eye, two had a nonreactive pupil, and one had had intracapsular cataract extraction at age 28. CONCLUSIONS: Loss of dynamic iridolenticular contact may help to protect against development of glaucoma in eyes with XFS.- - - - - - - - - - ranking = 1keywords = extraction (Clic here for more details about this article) |
2/4. Dislocation of the lens nucleus into the vitreous cavity after standard hydrodissection.PURPOSE: Having encountered dislocation of the lens nucleus into the vitreous cavity immediately after continuous tear capsulorhexis and hydrodissection of the nucleus, we examined common features of eyes with this complication. methods: We reviewed consecutive cases of cataract extraction. RESULTS: The complication occurred in four of 10,126 eyes. All four eyes were in elderly patients and except for the patient whose contralateral eye had pseudoexfoliation syndrome, all eyes had an increased axial length. CONCLUSION: In elderly patients with eyes that have a long axial length or pseudoexfoliation, we recommend performing hydrodissection with extreme care and only when necessary.- - - - - - - - - - ranking = 1keywords = extraction (Clic here for more details about this article) |
3/4. cataract extraction and intraocular lens implantation in eyes with phacomorphic or phacolytic glaucoma.We describe nine patients who had phacomorphic or phacolytic glaucoma. After intraocular pressure (IOP) was reduced medically, all patients had extracapsular cataract extraction. All had intraocular lens implantation except one. The surgery improved visual acuity and resulted in normal IOP in all eyes.- - - - - - - - - - ranking = 5keywords = extraction (Clic here for more details about this article) |
4/4. A case of true exfoliation.Using light and transmission electron microscopy, we have performed a histopathological evaluation of the anterior lens capsule, isolated during cataract extraction from an eye revealing a cellophane-like membrane on the lens surface of the pupil area. In addition to light microscopy showing one third of the anterior capsule had partially detached, transmission electron microscopy demonstrated irregular alignment of capsular structure near the detached regions. These microscopic features, together with clinical findings, led us to believe that this is a case of true exfoliation.- - - - - - - - - - ranking = 1keywords = extraction (Clic here for more details about this article) |
