1/3. Pars plana vitrectomy for persistent, visually significant vitreous opacities.PURPOSE: To evaluate the role of vitrectomy in patients with persistent, visually disabling vitreous opacities. methods: Six consecutive eyes of five men (age 58-66 years) with pseudophakia or aphakia and vitreous opacities resulting in visual symptoms for more than 1 year that underwent vitrectomy were retrospectively reviewed. Postoperative questionnaires regarding functional performance and quality-of-life issues were completed by the participants to assess subjective patient satisfaction. RESULTS: Postoperative Snellen visual acuity was improved or equal to preoperative acuity in all cases (8-44 month follow-up) and there were no surgical complications. All patients expressed high satisfaction with overall visual function. Analysis of the National eye Institute Visual Function Questionnaire-39 indicated that general vision, near activities, distance activities, mental health, role difficulties, and peripheral vision were significantly improved (P < 0.05) following surgical intervention. CONCLUSIONS: vitrectomy may be indicated in a select group of patients with visually disabling vitreous floaters, although objective assessment of visual dysfunction from vitreous floaters requires further evaluation.- - - - - - - - - - ranking = 1keywords = pseudophakia (Clic here for more details about this article) |
2/3. Cystoid macular edema in aphakia and pseudophakia after use of prostaglandin analogs.Prostaglandin analogs are powerful ocular hypotensive agents that may also be associated with a breakdown of the blood-retinal barrier and cystoid macular edema. The association is evident in pseudophakic or aphakic patients. This paper presents a case of unilateral latanoprost-associated clinical cystoid macular edema in a bilaterally pseudophakic patient; the only difference between the two eyes was the presence of a capsulotomy in the affected eye. We review the literature concerning prostaglandin analog-associated cystoid macular edema, as well as the evidence for prostaglandin analog-associated breakdown of the blood-retinal barrier. Although some evidence is suggestive of a connection between prostaglandin analogs and cystoid macular edema, many questions concerning the complex physiology of prostanoids remain. Until our understanding of these issues is more advanced, judicious use of prostaglandin analogs in patients at risk for cystoid macular edema would be prudent.- - - - - - - - - - ranking = 4keywords = pseudophakia (Clic here for more details about this article) |
3/3. Ocular axial length changes in a pediatric patient with aphakia and pseudophakia.Excessive eye elongation can be induced in experimental animals by visual deprivation. A tendency toward myopic refraction or shift in pediatric aphakia has been recorded in some children. In this report, we present the case of an 18-year-old patient who had developmental cataracts treated at seven years of age with bilateral cataract extraction and implantation of an intraocular lens in one eye only. Axial length of the eye with a contact lens increased compared with the eye with the intraocular lens.- - - - - - - - - - ranking = 4keywords = pseudophakia (Clic here for more details about this article) |
