1/13. Cystoid macular edema associated with topically applied epinephrine in aphakic eyes.A 69-year-old man with bilateral open-angle glaucoma and nonfiltering iridencleisis scars underwent combined cataract extraction and glaucoma filtering operations in each eye. Later, he again required intensive medical therapy including topically applied echothiophate iodide, epinephrine, and acetazolamide to control his glaucoma. Topical instillation of epinephrine repeatedly resulted in reversible cystoid macular edema in each eye. The macular changes were documented by fluorescein angiography. The clinical and angiographic features of the macular edema in this patient did not differ from cystoid macular edema seen in other ocular conditions.- - - - - - - - - - ranking = 1keywords = extraction (Clic here for more details about this article) |
2/13. Development of epithelial downgrowth several decades after intraocular surgery.PURPOSE: To report the management of a patient with the longest reported interval between intraocular surgery and the development of epithelial downgrowth. methods: A 53-year-old man who underwent right eye penetrating keratoplasty in 1970 for keratoconus and removal of an iris cyst in 1977 developed epithelial downgrowth 25 years after cyst removal. RESULTS: The area of epithelial downgrowth was initially treated with cryotherapy. Two weeks postoperatively, the patient had no resolution of epithelial downgrowth and developed diffuse corneal edema. Penetrating keratoplasty was performed along with extracapsular cataract extraction. At 6 months of follow-up, the patient's graft was clear, without evidence of recurrence of epithelial downgrowth, and he had 20/50 visual acuity. CONCLUSION: Epithelial downgrowth is an uncommon yet serious complication of intraocular surgery, making early detection of this condition important. This case illustrates that epithelial downgrowth can occur several decades after intraocular surgery.- - - - - - - - - - ranking = 1keywords = extraction (Clic here for more details about this article) |
3/13. Scleral cyst formation following extracapsular cataract extraction.Two patients who underwent extracapsular cataract surgery through corneal incisions developed scleral cysts 2 and 6 years later, respectively. The cysts involved the sclera without extension into the cornea or anterior chamber. To prevent further thinning of the sclera, only the anterior walls were excised and the posterior walls were mechanically debrided using alcohol and sponges. Histopathologic examination supported the clinical diagnosis of scleral cysts. No recurrence was seen. Scleral cyst formation may be encountered as a late complication of cataract surgery. Excision of the anterior wall coupled with removal of the epithelial lining of the posterior wall with alcohol may considerably lessen the likelihood of recurrence.- - - - - - - - - - ranking = 4keywords = extraction (Clic here for more details about this article) |
4/13. Intraoral extraction of cheek skin cyst.BACKGROUND: When a physician encounters a benign subcutaneous cyst in the cheek, his or her decision whether to excise and how to excise the cyst takes into account the potential risk of postsurgical scarring. OBJECTIVE: To describe and show an intraoral buccal mucosal approach to excising a cyst in the inferior-anterior cheek so that skin scarring is avoided. METHOD: An incision was made intraorally in the buccal mucosa, and dissection was carried through the buccinator muscle until the cyst wall was seen. Careful separation of tissue around the cyst was done by blunt dissection, and the unruptured cyst was removed through the buccal mucosal incision. RESULT: The entire intact cyst was removed without creating any excision marks in the cheek skin. No complications were encountered, and buccal mucosal healing was excellent. CONCLUSION: A buccal mucosal intraoral approach is an alternative to a percutaneous excision to remove a cyst in the lower cheek region. The intraoral approach avoids a visible scar on the cheek skin.- - - - - - - - - - ranking = 4keywords = extraction (Clic here for more details about this article) |
5/13. Inadvertent filtering blebs following cataract extraction.An inadvertent filtering bleb is a complication of cataract extraction that typically occurs during the first few months of the postoperative period. These blebs may be leaking or nonleaking. The sequelae are discussed for both types, with the former being more threatening. Different aspects of cataract surgery may raise or lower their incidence, although newer techniques have reduced its risk. Two atypical cases are presented.- - - - - - - - - - ranking = 5keywords = extraction (Clic here for more details about this article) |
6/13. Postsurgical hematic cyst simulating a conjunctival melanoma.A 75-year-old man had undergone bilateral intracapsular cataract extraction and then a scleral buckling procedure for an aphakic retinal detachment in the right eye. He presented 15 years later with a dark brown mass in the superior fornix of his right eye. On the basis of the clinical findings, the diagnosis of a conjunctival melanoma was considered. The lesion was surgically excised and found to be a chronic hematic cyst that arose adjacent to a episcleral sponge placed at the time of retinal detachment surgery. Hematic cysts should be included in the differential diagnosis of pigmented conjunctival lesions.- - - - - - - - - - ranking = 1keywords = extraction (Clic here for more details about this article) |
7/13. Pseudophakic choroidal detachment with cyclodialysis cyst.Two cases of spontaneous pseudophakic ciliochoroidal detachment, associated with extracapsular cataract extraction, posterior chamber intraocular lens implantation with intact posterior capsules, and small cyclodialysis clefts are documented. In both patients, the choroidal detachments occurred in a delayed fashion following uncomplicated cataract surgery and both presented with characteristic ocular hypotony. Although one patient required surgical management, both patients regained excellent vision after closure of the clefts and resolution of the ciliochoroidal detachments.- - - - - - - - - - ranking = 1keywords = extraction (Clic here for more details about this article) |
8/13. Epithelial cyst of anterior segment following cataract surgery.A 57-year-old male was evaluated 1 year after cataract extraction for a mass in the anterior segment of the eye. ultrasonography, transillumination, and fluorescein angiography suggested that the lesion was a melanoma. Histopathologically, it proved to be an epithelial cyst replacing a portion of the iris and ciliary body.- - - - - - - - - - ranking = 1keywords = extraction (Clic here for more details about this article) |
9/13. A possible inflammatory reaction in a lateral neck cyst (branchial cyst) because of odontogenic infection.We present the case of a woman who suffered from an acutely infected diffuse mass in the right neck. This mass had grown rapidly after difficult extraction of a tooth. Histologic analysis of the excised material revealed a lateral neck cyst with a lymph node that showed signs of an acute inflammation near the cyst. These findings support the theory that a preexisting lateral neck cyst may be "activated" by an intraoral inflammation. The different theories of the origin of lateral neck cysts are presented and discussed in the context of the case description.- - - - - - - - - - ranking = 1keywords = extraction (Clic here for more details about this article) |
10/13. Epithelial inclusion cyst of the iris.We describe the clinical presentation, high-frequency ultrasound biomicroscopic characteristics, and pathologic findings associated with a conjunctival inclusion cyst within the iris. The patient had undergone an uncomplicated extracapsular cataract extraction with posterior chamber intraocular lens insertion 9 months prior to presenting with a progressively enlarging iris mass. A clinical examination revealed a solid-appearing white tumor within the midiris stroma, accompanied by limbal-conjunctival hyperemia and anterior chamber inflammation. Ultrasound biomicroscopy revealed an egg-shaped solid iris stromal tumor that displaced the pigment epithelium. The mass was composed of three concentric layers of different echogenicity: a moderately reflective mantle, a less reflective middle zone, and a hyperreflective core. Within 3 days of initiation of topical corticosteroid therapy (prednisolone acetate, 0.5 mg per drop four times daily), the tumor enlarged and induced a plasmoid aqueous and a hypopyon. Histopathologic study revealed a conjunctival inclusion cyst with evidence of acute and chronic inflammation. We have found that the diagnosis of epithelial inclusion cyst within the iris can be aided by an ultrasound evaluation. This case also suggests that it may be preferable to excise these tumors prior to topical corticosteroid treatment.- - - - - - - - - - ranking = 1keywords = extraction (Clic here for more details about this article) |
