ABSTRACT Age-related macular degeneration is the leading cause of vision loss in elderly individuals, as well as a medical and socio-economic challenge. The treatment of dry age-related macular degeneration is based on vitamin supplementation. New treatment studies are focused on preventing the progression of degeneration and repopulating the atrophic macula. Recently, research on the treatment of neovascular age-related macular degeneration experienced a breakthrough with the advent of anti-vascular endothelial growth factor inhibitors. Nevertheless, despite the fact that ranibizumab, aflibercept, and bevacizumab are effe...

Trocar-assisted, flanged haptics, sutureless intrascleral fixated intraocular lens implantation combined with Descemet membrane endothelial keratoplasty
This article reports a combined technique of sutureless intrascleral fixated intraocular lens implantation and Descemet membrane endothelial keratoplasty in a patient with anterior pseudophakic bullous keratopathy. Two scleral tunnels were created, corneal incisions were made, and a foldable intraocular lens was cut and removed from the anterior chamber. After performing anterior vitrectomy, a 3-piece foldable intraocular lens was implanted into the anterior chamber. One of the intraocular lens haptics was grasped with a forceps and pulled out from the scleral tunnel. Then, the end of the haptic was cauterized. Similar man...

Retinal ischemia following mandible tumor treatment with steroid injection
We report a case of retinal arteriolar ischemic disease following central giant cell granuloma management with local injected corticosteroids.RESUMO O granuloma central de c élulas gigantes é um tumor ósseo raro que afeta pacientes jovens com comprometimento anatômico e funcional da maxila e mandÃbula. A terapia com injeção de esteroides constitui uma modalidade de tratamento menos invasiva para o controle da doença em casos selecionados. A isquemia retiniana é uma complicação relatada em vários procedimentos médicos, incluindo intervenções odontológicas, e pode levar à perda da visão com mau prognóstic...

Corneal suture for acute corneal hydrops secondary to post-LASIK ectasia: a case report
In this report, we describe a case of corneal ectasia after laser-assisted in situ keratomileusis), which progressed with acute hydrops and aqueous leakage and required a suture for correction.RESUMO A ectasia corneana é uma das principais complicações das cirurgias refrativas. Neste caso, descrevemos um caso de ectasia corneana induzida por laser-assisted in situ keratomileusis, que evoluiu com hidrópsia aguda e extravasamento de humor aquoso, necessitando de sutura corneana.

Angioid streaks and optic disc drusen in cherubism: a case report
ABSTRACT A 65-year-old female patient was referred to our hospital for evaluation for cataract surgery. Her past medical history included corrective jaw surgeries for facial deformities that developed during infancy and persisted through early adulthood. A complete ophthalmological examination revealed bilateral angioid streaks, drusen in both optic disc areas, and a subretinal neovascular membrane in the left macula. Genetic analysis revealed a mutation in the SH3BP2 gene compatible with the diagnosis of cherubism. Clinical and laboratory evaluation revealed no additional systemic disorders. Cherubism is a rare disease ch...

ETDRS panretinal photocoagulation combined with intravitreal ranibizumab versus PASCAL panretinal photocoagulation with intravitreal ranibizumab versus intravitreal ranibizumab alone for the treatment of proliferative diabetic retinopathy
Conclusions: Intravitreal injection alone or combined with single- or multiple-spot panretinal photocoagulation yielded similar outcomes with respect to mean change in best-corrected visual acuity, central subfield macular thickness, and fluorescein leakage from active neovascularization at up to one-year of follow-up. All subjects provided written informed consent to participate (NCT02005432 in clinicaltrials.gov).RESUMO Objetivo: Comparar as medidas de acuidade visual, espessura macular central e área de neovasos ativos na anÂgiofluoresceinografia submetidos a panfotocoagulação retiniana padrão ETDRS associado a in...

Evaluation of the retinal vasculature of patients with branch retinal vein occlusion using optical coherence tomography angiography
Conclusions: Vascular density in capillary plexuses and deep capillary plexuses was lower in the eyes affected by branch retinal vein occlusion. Furthermore, the lower vascular density noted in the contralateral eyes indicates that changes most likely occurred in these eyes prior to the appearance of any clinically detectable alterations, reflecting the early signs of hypertensive retinopathy.RESUMO Objetivo: Avaliar a densidade vascular do plexo capilar superficial e profundo da retina, usando angiografia por tomografia de coer ência óptica em pacientes com oclusão de ramo da veia central da retina, comparando o olho ...

Novel low-cost approach to the treatment of ocular surface squamous neoplasia using pattern scanning laser photocoagulation
Conclusion: Short-term results of the laser photocoagulation approach for the treatment of ocular surface squamous neoplasia conjunctival lesions were favorable, with a 74% success rate observed in immunocompetent patients. This novel strategy is a less resource-intensive alternative that could demonstrate its usefulness in settings with shortages in operating rooms and in recurrent cases. Studies with longer follow-ups and larger sample sizes are warranted to confirm our findings and evaluate the effectiveness of laser treatment in association with topical chemotherapy.RESUMO Objetivo: Avaliar a seguran ça e o efeito d...

Association between disorganization of the retinal inner layers and capillary nonperfusion area in patients with retinal vein occlusion
Conclusions: Disorganization of the retinal inner layers appears to be a correlated biomarker of capillary ischemia in retinal vein occlusion. The extent of disorganization of the retinal inner layers was strongly correlated with the capillary nonperfusion area. This may support the notion that the extent of disorganization of the retinal inner layers can be used as an easily obtainable and crucial surrogate marker of capillary ischemia.RESUMO Objetivo: Determinar a correla ção entre a exÂtensão da desorganização das camadas internas da retina, que constitui um parâmetro da tomografia de coerência óptica de domÃ...

Swept-source optical coherence tomography findings in premature children with a history of retinopathy of prematurity at 5 years of age
Conclusions: Visual functional outcomes were better in term-born healthy children compared with those noted in children with a history of treated retinopathy of prematurity and spontaneously regressed retinopathy of prematurity. Laser treatment exerted a signifi Âcant effect on central foveal thickness in premature children at the age of 5 years, as revealed by swept-source optical coherence tomography.RESUMO Objetivo: Comparar a espessura central foveal, a da camada de fibras nervosas da retina e a da cor óide subfoveal através da tomografia de coerência óptica swept-source em crianças de 5 anos de idade com histÃ...

Solitary fibrofolliculoma: a retrospective case series review over 18 years
Conclusion: Solitary fibrofolliculoma is a rare lesion, seldom affecting the eyelids. We reported 11 cases, and the third case reported thus far in the literature affecting the lids. Diagnosis may be easily mis sed due to the nonspecific symptoms and clinical appearance. Therefore, it is necessary to perform excisional biopsy and histological examination for the recognition of this lesion.RESUMO Objetivo: o objetivo deste estudo foi relatar uma s érie de casos de fibrofoliculoma solitário, uma lesão raramente observada nas pálpebras. Demografia, bem como aspectos clÃnicos e histológicos da lesão foram avaliados. M...

Impact of different clear corneal incision sizes on anterior corneal aberration for cataract surgery
Conclusions: The results showed that 2.2-mm coaxial micro-incision cataract surgery and 2.75-mm coaxial small-incision cataract surgery did not significantly degrade the total higher-order aberrations of the anterior cornea. However, the surgically induced changes in total higher-order aberration showed a significant difference between the two procedures, with a slight reduction after 2.2-mm coaxial micro-incision cataract surgery and a slight increase after 2.75-mm coaxial small-incision cataract surgery. Phaco time and power used during surgery had no impact on corneal aberrations.RESUMO Objetivo: Investigar o impacto d...
