1/8. Diagnosing glaucoma in pediatric aphakia.BACKGROUND: Cataracts pose a serious threat to the visual system in infants and children, requiring prompt surgical intervention and rehabilitation to optimize visual development. glaucoma is a serious complication following cataract surgery in infants and can lead to loss of vision. early diagnosis of glaucoma, however, can be quite challenging in these patients. case reports: Three cases are presented in which comeal edema was the initial presenting sign that led to the diagnosis of glaucoma during routine contact lens follow-up examinations for pediatric aphakia. CONCLUSION: The contact lens practitioner, during the course of management of aphakic infants and children, should always be suspicious of glaucoma as a complication of cataract surgery, and the presenting sign may be corneal edema.- - - - - - - - - - ranking = 1keywords = aphakia (Clic here for more details about this article) |
2/8. A case of cystoid macular edema associated with latanoprost ophthalmic solution.BACKGROUND: Although there have been reports of adverse effects after use, it is unclear whether latanoprost ophthalmic solution contributes to the development of cystoid macular edema (CME). CASE: A 71-year-old man underwent lens extraction, the insertion of an intraocular lens, and vitrectomy for elevated intraocular pressure (IOP) associated with lens subluxation in the left eye. After the surgery, antiglaucoma ophthalmic solutions controlled IOP well for over a year, maintaining good visual acuity with no abnormalities in the fundus. OBSERVATIONS: Two months after the previously prescribed antiglaucoma ophthalmic solutions were replaced by latanoprost, the patient's visual acuity decreased and CME developed. When latanoprost was replaced by other antiglaucoma ophthalmic solutions for controlling IOP, CME disappeared and visual acuity returned to the base level. CONCLUSIONS: Latanoprost may be involved in the development of CME. patients who have undergone vitreous surgery or those with aphakia should be carefully observed for the possible development of CME associated with the use of latanoprost, even a long time after surgery.- - - - - - - - - - ranking = 0.2keywords = aphakia (Clic here for more details about this article) |
3/8. Difficult vertical diplopia studied by video-oculography in aphakia after contact lens use. A case report.PURPOSE: To establish the utility of a video-oculography system (3D-VOG) in the diagnosis of a patient with difficult idiopathic vertical diplopia. CASE REPORT: We present a clinical case of an 87 year old female who was operated for glaucoma and cataract with the intracapsular technique in both eyes. She reported vertical diplopia with the use of contact lenses but not while using her aphakia spectacles. A complete ophthalmological study was carried out with special interest in the ocular motility study with 3D-VOG. RESULTS: Besides the hypertropia in lateroversion of the non-fixing eye, the video-oculography showed an incyclotorsion of the hypertropic eye, a fundamental factor for the differential diagnosis between bilateral superior oblique overaction and DVD or dissociated vertical divergence. Such a torsional strabismic deviation is very difficult to detail by other methods and is the important clue for diagnosis. The 3D-VOG made this diagnosis possible. CONCLUSIONS: The occurrence of a vertical diplopia with use of contact lenses, and not with spectacles, is explained by the limitation of ocular gaze movements with the aphakia spectacles which limitation is not found with the use of contact lenses, with diplopia appearing in the more extreme lateroversion possible with the contact lenses. The 3D-VOG system enabled us to analyze torsional movements in lateroversion that allowed the diagnosis of bilateral superior oblique overaction to be made.- - - - - - - - - - ranking = 1.2keywords = aphakia (Clic here for more details about this article) |
4/8. Histopathologic study of the Molteno glaucoma implant in three patients.Three eyes with the Molteno glaucoma implant (one eye with epithelial downgrowth, one eye with iridocorneal endothelial syndrome, and one eye with aphakia and glaucoma) were enucleated two to six years after implantation. Histopathologic examinations disclosed no evidence of erosion of sclera or conjunctiva of the eye by the glaucoma implant device. In the outer layers of the bleb wall, few and mostly degenerated inflammatory cells were present, which represented a minimal inflammatory reaction. Scanning electron microscopy of the tubes in these three patients showed that the tube was intact, patent, and without signs of degradation. The tube entering into the anterior chamber caused no appreciable inflammation and maintained its patency even when downgrowth epithelial cells lined the anterior chamber. The Molteno plate induced little or no inflammatory reaction. Therefore, the Molteno glaucoma implant is a useful device for patients with high risk for failure after surgery for glaucoma.- - - - - - - - - - ranking = 0.2keywords = aphakia (Clic here for more details about this article) |
5/8. Prevention and management of delayed suprachoroidal hemorrhage after filtration surgery.We report two new cases of massive delayed nonexpulsive suprachoroidal hemorrhage (DNSH) following a filtering operation in the aphakic eyes of elderly patients with glaucoma. A timely surgical drainage resulted in full recovery of preoperative visual acuity in both of our patients. As we combine our cases with a series of 18 similar cases of others in the literature, the following conclusions emerge. Limited DNSH does not require surgical intervention for a favorable visual outcome. Massive DNSH, however, requires timely and appropriate surgical intervention to achieve a favorable visual outcome and to avoid persistent hypotony. The most effective surgical intervention is drainage of the suprachoroidal hemorrhage and re-formation of the anterior chamber, but without concomitant vitrectomy. In both limited and massive DNSH, the final visual outcome is not determined by the worst vision at the time of DNSH. Some of the known and suspected risk factors of DNSH following filtering surgery are old age, aphakia, postoperative hypotony, a history of vitreous manipulation or complication, general anesthesia, increased venous pressure, use of fluorouracil, and high myopia. In view of these risk factors, we recommend several preventive measures for decreasing the incidence of DNSH following filtering surgery.- - - - - - - - - - ranking = 0.2keywords = aphakia (Clic here for more details about this article) |
6/8. retinal detachment and miotic therapy.We studied a series of 34 eyes in 31 patients in whom retinal detachment occurred during miotic therapy. In 14 eyes, the duration of miotic use before the development of detachment was two months or less. Most detachments occurred in detachment-prone eyes either by virtue of myopia (62%), aphakia (24%), ipsilateral lattice degeneration (38%) or retinal pathology, in the fellow eye (50%). Virtually all detachments were rhegmatogenous. Distributions of retinal breaks are similar to the corresponding profiles in detached eyes not receiving miotics. The observed phenomena may be accounted for mechanistically, either with or without the role of miotics, so a specific causal role cannot be assigned to any given miotic in any given case. However, our data suggest that detachment-prone eyes may be at increased risk with miotic use, and thus demand careful retinal evaluation and prophylaxis when ominous peripheral symptoms are present.- - - - - - - - - - ranking = 0.2keywords = aphakia (Clic here for more details about this article) |
7/8. Congenital aphakia in Peters' anomaly syndrome. A case report.The authors report a case of congenital bilateral corneal opacities in which one of the eyes was enucleated because of malignant glaucoma and corneal perforation. Corneal defects and iridocorneal adhesion were found, but aphakia was the major pathologic ocular finding. The clinical picture and pathology study indicated this case as a Peters' anomaly presenting congenital aphakia.- - - - - - - - - - ranking = 1.2keywords = aphakia (Clic here for more details about this article) |
8/8. Subconjunctival silicone oil drainage through the Molteno implant.To describe silicone oil drainage from the vitreous cavity to the subconjunctival space through a Molteno implant. A 52-year-old aphakic man with a Molteno implant inserted after lensectomy, vitrectomy and intravitreal silicone oil injection visited our hospital. The Molteno tube was located in the anterior chamber with two silicone oil drops on it. Corneal dellen, induced by marked bleb-like elevation of the conjunctiva was noted during follow-up and excision biopsy was attempted. The conjunctival elevation consisted of innumerable microdrops of silicone oil enclosed by inflammatory subconjunctival tissue. Silicone oil as well as aqueous humor had drained through the Molteno implant and glaucoma implant surgery may thus not be appropriate for the control of intraocular pressure of aphakia by intravitreal silicone oil before removal of oil.- - - - - - - - - - ranking = 0.2keywords = aphakia (Clic here for more details about this article) |
