Fovea-threatening and fovea-involving peripheral Coats disease: effects of posture and intervention.

Background: We believe that our experience with patients presenting with Coats disease and macular sparing should be shared with our colleagues. We would like to show the effect of posture and prompt intervention in cases with fovea-threatening and/or fovea-involving peripheral Coats disease (FTPCD). This association has been poorly debated in our specialty and literature.

Birdshot retinochoroiditis in Brazil: a multicenter review of 40 patients.

Background: Birdshot retinochoroiditis (BRC) is a rare and chronic bilateral uveitis mostly found in Caucasians. As few data are available about the clinical course of BRC in Hispanic patients, we aimed to report the clinical findings and the evolution of BRC in Brazilian patients.

Methods: This retrospective cohort multicenter nationwide study was performed by analyzing the records of patients with BRC diagnoses from Brazilian ophthalmological centers from April 1995 to May 2020.

Ultrasonographic characteristics of active ocular toxoplasmosis.

Purpose: To evaluate ophthalmic ultrasonographic findings associated with active ocular toxoplasmosis.

Methods: Forty-seven eyes with active ocular toxoplasmosis in 47 patients were subjected to ocular ultrasonography using the transpalpebral technique (10-MHz transducer) and fundus photography. Patient medical records were retrospectively reviewed.

Focal phototherapeutic keratectomy for the treatment of apical leucoma syndrome.

The following report describes a case of apical leucoma syndrome after hyperopic photorefractive keratectomy following hyperopic laser in situ keratomileusis and the subsequent treatment of this complication with focal phototherapeutic keratectomy. The patient underwent focal transepithelial phototherapeutic keratectomy of 70 mm ablation and 1.5 mm diameter after pupil and ablation offset correction.

Surgical outcomes of rhegmatogenous retinal detachment associated with ocular toxoplasmosis.

Purpose: To evaluate the anatomical and functional outcomes of surgical treatment of retinal detachment secondary to ocular toxoplasmosis.

Methods: A retrospective analysis of data from patients who had undergone vitreoretinal surgery for retinal detachment secondary to ocular toxoplasmosis was conducted. The parameters that were analyzed include surgical procedures, anatomical outcomes, visual acuity, and postoperative complications.

Descemet membrane endothelial keratoplasty in multifocal pseudophakic eyes.

Purpose: This report describes the use of Descemet membrane endothelial keratoplasty for the management of endothelial decompensation after multifocal intraocular lens implantation.

Methods: In this retrospective study, we reviewed and assessed the surgical outcomes of 9 patients (9 eyes) who underwent Descemet membrane endothelial keratoplasty after multifocal intraocular lens implantation.

Results: Corneal edema occurred due to Fuchs endothelial corneal dystrophy (n=3), pseudophakic bullous keratopathy (n=3), Descemet's membrane detachment (n=2), and toxic anterior segment syndrome (n=1).

PRESUMED TUBERCULOUS MULTIFOCAL RETINITIS IN PATIENTS UNDER TREATMENT WITH BIOLOGIC AGENTS.

Purpose: To report unique retinal fundus lesions and treatment outcomes of intraocular tuberculosis in patients under anti-tumor necrosis factor treatment.

Methods: Retrospective review of two patients with laboratorial evidence of tuberculosis who had bilateral ocular signs and symptoms not attributable to other diseases. Multimodal imaging was analyzed at the time of presentation and after the treatment initiation.

Combined branch retinal vein and artery occlusion in toxoplasmosis.

A 22-year-old man complained of low visual acuity and pain in his left eye for five days. His ophthalmological examination revealed 2+ anterior chamber reaction and a white, poorly defined retinal lesion at the proximal portion of the inferotemporal vascular arcade. There were retinal hemorrhages in the inferotemporal region extending to the retinal periphery.

Bilateral acute depigmentation of the iris: a case report.

Bilateral acute depigmentation of the iris (BADI) is a new clinical entity of unknown etiology and is characterized by bilateral, symmetrical, and simultaneous depigmentation of the iris with focal or diffuse stromal atrophy; this condition generally has a good prognosis. We present a case of a 26-year-old woman who noted a spontaneous change in the iris color in both eyes in the last 2 months. The ophthalmological findings were atrophy of the iris stroma and pigmentation of the trabecular meshwork, without affecting the pigmented epithelium of the iris.

Comparative study of visual functions in premature pre-school children with and without retinopathy of prematurity.

Purpose: Observe whether there are differences in visual functions among premature infants with treated retinopathy of prematurity (ROP) in relation to preterm infants with ROP and spontaneous regression; and among these two groups with ROP and the control group without ROP.

Methods: Cross-sectional observational no blind study. Premature infants were born between 06/199206/2006 and were exam between 06/200912/2010; registered in data of Hospital de Olhos Sandalla Amin Ghanem; with gestational age less than or equal to 32 weeks and 1,599 g born weigh; without ROP and ROP stages II or III, in one of the eyes, with spontaneous regression or with treatment; at least three visits during the selection period at maximum 6 months in the first exam and minimum 4 years of age in reassessment (chronological age) were include.

[Corneal wavefront-guided photorefractive keratectomy with mitomycin-C for consecutive hyperopia after radial keratotomy].

Purpose: To assess the efficacy, predictability and stability of corneal wavefront-guided photorefractive keratectomy (PRK) for correcting hyperopia and astigmatism after radial keratotomy.

Methods: In a prospective study, 60 eyes of 36 consecutive patients were treated with corneal wavefront-guided PRK with 0.02% mitomycin-C using an Esiris-Schwind excimer laser.

[Posterior segment changes in microphthalmic eyes: case report].

Microphthalmos is a developmental ocular disorder defined as a small eyeball. The condition can be associated with abnormalities of anterior and posterior segments. The most common anterior characteristics include corneal opacities, angle-closure and a shallow anterior chamber and cataract.

[Clinical and tomographic aspects of macular microholes].

Purpose: To describe the clinical aspects and evaluate optical coherence tomography of macular microholes.

Methods: Seven patients were assessed (8 eyes) with microholes of the macula. All patients underwent complete eye examination, fundus photography, fluorescent angiography and OCT-3 imaging.

[Fitting Monocurve and Bicurve (Soper-McGuire design) rigid gas-permeable contact lenses in keratoconus patients: a prospective randomized comparative clinical trial].

Purpose: To evaluate the clinical performance of Monocurve and Bicurve (Soper-McGuire design) rigid gas-permeable contact lens fitting in patients with keratoconus.

Methods: A prospective and randomized comparative clinical trial was conducted with a minimum follow-up of six months in two groups of 63 patients. One group was fitted with Monocurve contact lenses and the other with Bicurve Soper-McGuire design.

[Topographically-guided photorefractive keratectomy for the management of secondary hyperopia following radial keratectomy].

Purpose: To describe a topographically guided photorefractive keratectomy technique for the management of secondary hyperopia following radial keratectomy.

Methods: A retrospective study was carried out in patients where a topographically guided photorefractive keratectomy technique was performed for the management of secondary hyperopia following radial keratectomy. The patients had preoperatively at least 3 diopters of hyperopia.

[Optical coherence tomography in choroidal osteoma: case report].

The authors present a case of choroidal osteoma diagnosed in a 62-year-old male patient. A well-defined and slightly elevated lesion located in the posterior pole of the right eye associated with internal vasculature and choroidal neovascularization at its superior and inferior temporal edge were suspicious of the tumor. Confirmation of diagnosis was obtained with A and B ecography and computed tomography.
