    Antibiotic irrigation of the capsular bag to resolve low-grade endophthalmitis

    No full text
    Chronic, low-grade endophthalmitis after cataract surgery with intraocular lens (IOL) implantation is often unresponsive to antibiotic therapy, probably because of low drug penetration into the capsular bag. To increase the drug concentration at the infection site, we irrigated the capsular bag with antibiotics. Within 6 weeks, endophthalmitis resolved in three consecutive patients with positive aqueous cultures. Visual acuity improved from finger counting or less to 20/40 or better in all cases. No recurrence was seen in the 12 to 19 month follow-up. Antibiotic irrigation of the capsular bag can resolve chronic, low-grade endophthalmitis in culture-positive patients unresponsive to the same drugs administered by other routes, including conventional intraocular injection. With this approach there is minimal surgical trauma and the IOL is retained

    DSAEK for the treatment of endothelial disease: Results in the initial 100 cases

    Purpose: To evaluate the learning curve and the outcome of Descemet Automated Endothelial Keratoplasty (DSAEK) in patients with primary or secondary endothelial decompensation. Methods: DSAEK was performed in 100 eyes with endothelial decompensation (Fuchs Dystrophy n = 59; pseudophakic bullous keratopathy n = 33; failed corneal graft n = 8). All patients underwent a standard procedure including the following steps: Descemet membrane and endothelium removal from the recipient cornea under air; inferior peripheral iridectomy; microkeratome-assisted preparation of a donor lamella consisting of deep stroma and endothelium (between 100 and 200 micron in thickness), which is punched to desired size (8.5 to 9 mm) from the endothelial side; graft delivery with a specially designed glide; complete anterior chamber air fill to obtain firm attachment of the donor lamella and air-tight closure of all surgical wounds. In 46 cases phacoemulsification with implantation of an intraocular lens into the capsular bag was combined with DSAEK surgery. Visual acuity, refraction and endothelial cell count were evaluated prospectively at 1, 3, 6, and 12 months after DSAEK. Results: As early as 1 month after surgery 76 of 100 patients had a best spectacle-corrected visual acuity (BSCVA) better than or equal to 0.5, with a refractive astigmatism within 1.5 Diopters (D). One year after surgery, 79 of 100 patients had a BSCVA better than or equal to 0.5, with a refractive astigmatism within 1.5 D. At this examination time 11 of 100 patients could see 1.0 or better and the average endothelial cell loss amounted to 22.5 ± 4.2 %. Conclusions: DSAEK surgery allows fast visual rehabilitation of patients with decompensated endothelium. Visual outcome is superior to that of conventional penetrating keratoplasty (PK) in terms of BSCVA and early stabilization. Endothelial cell loss also compares favourably to that recorded after PK

    Corneal epithelial dots following excimer laser photorefractive keratectomy

    No full text
    BACKGROUND: Map-dot-fingerprint epithelial changes of the cornea have been reported to occur as a consequence of trauma or surgical procedures, such as radial keratotomy. METHODS: We describe a case of dot-like changes in the corneal epithelium following excimer laser photorefractive keratectomy for the correction of myopia. Because the lesions were located centrally, possibly reducing visual acuity, the epithelium was removed mechanically. RESULTS: Dot-like changes recurred in the same areas 4 weeks after epithelial debridement. Best spectacle-corrected visual acuity improved from 20/200 to 20/100 and remained stable thereafter. CONCLUSIONS: Photorefractive keratectomy can lead to abnormal regeneration of epithelium basement membrane, possibly resulting in dot-like changes of corneal epithelium

    Modified surgical technique for autologous conjunctival transplantation after corneal alkali burn [Modifizierte Technik zur Autologen Bindehauttransplantation nach Hornhautveratzung]

    Background A modified conjunctival plastic for the treatment of unilateral alkali burn in presented. This procedure is aimed at both reconstructing the limbal region while eliminating the symblephara, thus allowing free ocular motility and partial recovery of corneal transparency.Patients and Methods Two patients suffering from unilateral alkali burn underwent a conjunctival plastic according to a technique modified from Kenyon. Preoperatively, both patients exhibited a fully vascularized. scarred cornea as well as extensive symblephara. By transplanting both limbal and bulbar autologous conjunctiva from the healthy eve to the injured one, it was possible in the two cases to reestablish the limbal and fornix anatomy.Results Postoperatively, free bulbar motility was achieved in both cases, while vision improved substantially only in the adult, not amblyopic patient who could obtain an uncorrected visual acuity of 0.05.Conclusion The modified conjunctival plastic employed in the two case...Background: A modified conjunctival plastic for the treatment of unilateral alkali burn is presented.

Conclusion: The modified conjunctival plastic employed in the two cases reported herein led to excellent anatomic results while allowing partial recovery of corneal transparency and improvement of vision
