KeraKlear Artificial Cornea Implantation Assisted by Femtosecond Laser in Eyes With Aniridia.

Purpose: The purpose of this study was to evaluate the feasibility of treating aniridia-associated keratopathy with a nonpenetrating artificial cornea in 2 patients with corneal blindness secondary to aniridia.

Methods: This was a prospective, nonrandomized, interventional study of 2 consecutive patients with corneal blindness caused by aniridia. Ophthalmological examination was performed before the nonpenetrating keratoprosthesis surgery and then repeated 1, 7, 15, 30, 90, and 180 days and subsequently every 90 days thereafter.

Clinical Aspects of Stevens-Johnson Syndrome and Toxic Epidermal Necrolysis With Severe Ocular Complications in Brazil.

Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) are acute and potentially fatal inflammatory vesiculobullous reactions that affect the skin and mucous membranes, and which are most often triggered by particular medications and infections. In Brazil, the drugs most frequently associated with TEN and SJS include cold medicine such as dipyrone and NSAIDs, followed by carbamazepine, phenobarbital, penicillin, and allopurinol. Genetic variations have been found to increase the risk of SJS/TEN in response to triggering factors such as medications.

Amniotic membrane transplantation with narrow-strip conjunctival autograft vs conjunctival autograft for recurrent pterygia.

Purpose: To compare amniotic membrane transplantation (AMT) associated with narrow-strip conjunctival autograft vs conjunctival autograft alone for the treatment of recurrent pterygium.

Methods: In this prospective consecutive interventional study, patients with recurrent pterygium were randomly divided into one of 2 groups; group 1: patients undergoing AMT associated with autologous conjunctival graft; and group 2: patients undergoing conjunctival autograft alone.

Results: Of the 80 operated eyes included in this study, 39 (group 1, mean patient age 52.

[Scleral contact lens for ocular rehabilitation in patients with Stevens-Johnson syndrome].

Purpose: To evaluate the efficacy of scleral contact lenses use on the management of ocular sequelae from Stevens-Johnson syndrome patients.

Methods: In a retrospective study, patients who suffered sequelae of Stevens-Johnson syndrome and started the use of scleral contact lenses were followed. Patients were submitted to an evaluation of symptoms through a questionnaire; ophthalmologic exam (visual acuity measurement, biomicroscopy, ocular surface staining with fluorescein drops, Schirmer test).

[Bullous keratopathy: etiopathogenesis and treatment].

Bullous keratopathy is characterized by corneal stromal edema with epithelial or subepithelial bullae due to cell loss and endothelial decompensation. In more advanced cases, subepithelial fibrosis, formation of a posterior collagenous layer or retrocorneal fibrous membrane, and corneal vascularization can occur. Decreased vision is present because the loss of corneal transparency with symptoms like tearing and pain caused by epithelial bullae that can rupture.

Postoperative subconjunctival corticosteroid injection to prevent pterygium recurrence.

Purpose: To report the outcome of postoperative subconjunctival injection of triamcinolone in eyes that underwent pterygium surgery and were at risk for recurrence.

Methods: Twelve eyes of 11 patients with primary (7 eyes) or recurrent (5 eyes) pterygia underwent excision and conjunctival autografting (4 eyes, 33.3%), amniotic membrane grafting (6 eyes, 50%), or both (2 eyes, 16.
