Intravitreal bevacizumab in pigmented rabbit eyes: histological analysis 90 days after injection.

Purpose: To evaluate bevacizumab toxicity in neurosensorial retina and retinal pigment epithelium in pigmented rabbit eyes by means of histological studies.

Methods: Thirty eyes of fifteen rabbits were distributed into three groups: sham group (S), that received a 0.1 ml balanced saline solution (BSS) intravitreal injection (10 eyes); group 1, that received a 1.

[Ipsilateral rotational autokeratoplasty with 0.5 mm resection of inferior corneal crescent, in keratoconus].

Purpose: To report the visual outcomes in keratoconus after ipsilateral rotating penetrating autokeratoplasty technique (IRPAK) associated with resection of 0.5 mm of inferior corneal crescent.

Methods: According to a prospective, longitudinal, series of cases, the authors analyzed visual results of six patients with keratoconus, who underwent an IRPAK, by two trepanations superiorly coincident and with a difference of 0.

[Analysis of the nerve fiber layer using GDx in pseudophakic patients with posterior capsular opacification].

Purpose: To evaluate if posterior capsule opacification (PCO) would alter the analysis of nerve fiber layer using the scanning laser polarimetry (GDx).

Methods: Pseudophakic non-glaucomatosous eyes (37 patients) underwent nerve fiber layer analysis using GDx before and after posterior capsulotomy with Nd:YAG Laser.

Results: In five eyes, GDx did not obtain acceptable images using the device's parameters of acquisition.

[Blue-on-yellow perimetry in tobacco and alcohol consumers].

Purpose: To evaluate the visual field changes in blue-on-yellow perimetry (B/Y) strategy 10-2 in alcohol and tobacco smoking consumers.

Methods: Forty-two eyes of twenty-one users were studied. Fifteen individuals were used as a control group.

[Clear lens extraction: visual outcomes and vitreoretinopathy frequence].

Purpose: To evaluate visual results and vitreoretinopathy and retinal detachment frequencies in patients with and without prophylactic pre-equatorial retinal photocoagulation, who underwent clear lens extraction (CLE) to correct myopia.

Methods: Thirty-five patients (60 eyes) that underwent clear lens extraction at the "Fundação Altino Ventura" had median follow-up of 20.5 months.

[Limbal relaxing incisions during cataract surgery: one-year follow-up].

Purpose: To evaluate astigmatism variation between preoperative, 1st and 12th postoperative month of patients who underwent cataract surgery with limbal relaxing incisions (LRI) aiming to reduce the preoperative astigmatism.

Methods: Sixteen patients who underwent cataract surgery by the phacoemulsification technique with a 5.5 mm escleral incision, at the Altino Ventura Foudation, between April and July of 2002.
