Optic neuritis and mydriasis after vaccination: a case report.

Background: Optic neuritis (ON) is an inflammatory demyelinating condition of the optic nerve, with various causes. Its incidence is higher in children and young adults than in older adults of both genders, but is more common in women than in men. ON is rarely associated with mydriasis, and it is seldom triggered by vaccines against tetanus and diphtheria.

A Comparative Study Between the Goldmann Applanation Tonometer and the Non-Contact Air-Puff Tonometer (Huvitz HNT 7000) in Normal Eyes.

Objective: To assess whether the non-contact air-puff tonometer (NCT) is an appropriate alternative to the Goldmann applanation tonometer (GAT) for measuring intraocular pressure (IOP).

Patients And Methods: An observational, cross-sectional, and comparative study with a quantitative approach was carried out. Two techniques for IOP measurements using the standard GAT and the NCT were compared.

Efficacy of Standard and Accelerated (10 Minutes) Corneal Crosslinking in Keratoconus Stabilization.

Purpose: To evaluate whether Accelerated CXL for 10 minutes is as effective as standard CXL for 30 minutes for the treatment of progressive keratoconus.

Patients And Methods: Eighty-two eyes of 62 patients with keratometry examinations performed before and 6 months after surgery were studied. A total of 39 eyes underwent standard CXL with UVA irradiation of 3 mW/cm for 30 minutes and 32 eyes underwent Accelerated CXL UVA irradiation of 9 mW/cm for 10 minutes.

Surgical debridement of corneal shield ulcers in pediatric patients: two case reports and a review of the literature.

Background: Ocular allergy is a common disease, especially in the pediatric population, with unpleasant and long-term consequences, including corneal complications and decreased visual acuity. This study reports two cases of corneal shield ulcer due to vernal keratoconjunctivitis, with good results of surgical debridement performed after failure of long-term clinical treatment. Furthermore, this study highlights that this therapeutic approach, although less common, is efficient in treating refractory cases that cause suffering in pediatric patients.

Phacoemulsification: an alternative for prophylaxis of a glaucomatous crisis.

Purpose: To evaluate the effectiveness of phacoemulsification for the prophylaxis of a glaucomatous crisis in the affected and contralateral eyes; to investigate the evolution of intraocular pressure levels after iridotomy and phacoemulsification; to assess the need for antiglaucoma medication after the proposed treatments; and to identify potential complications associated with phacoemulsification.

Patients And Methods: This retrospective observational study evaluated 22 eyes of 12 patients between September 2006 and September 2018, with a minimum follow-up period of 9 months.

Results: After iridotomy, a persistent increase in intraocular pressure was observed in 42.

Comparison of macular thickness by optical coherence tomography measurements after uneventful phacoemulsification using ketorolac tromethamine, nepafenac, vs a control group, preoperatively and postoperatively.

Purpose: To analyze, using optical coherence tomography, the macular thickness values of patient groups using nonsteroidal anti-inflammatory drug (NSAID) eye drops or artificial tears during uncomplicated cataract surgery.

Methods: A total of 77 eyes from 42 patients were analyzed. The patients were divided into three groups, each using one of the following ophthalmic sterile suspensions: nepafenac (21 eyes), propylene glycol (24 eyes), or ketorolac tromethamine (32 eyes).

Subjective evaluation of uncorrected vision in patients undergoing cataract surgery with (diffractive) multifocal lenses and monovision.

Purpose: To analyze patient satisfaction and difficulties with bilateral multifocal intraocular lenses (IOLs) implantation and aspheric monofocal IOLs implantation using monovision, after cataract surgery.

Materials And Methods: A total of 61 participants were included in the study, 29 with monovision and 32 with multifocal lenses. The inclusion criteria were patients undergoing phacoemulsification for bilateral visual impairment due to cataracts and presenting with postoperative visual acuity of 20/30 or better for distance and line J3 or better for near vision.

Acute corneal hydrops during pregnancy with spontaneous resolution after corneal cross-linking for keratoconus: a case report.

Background: Keratoconus may progress to acute corneal hydrops even after cross-linking. In some cases, keratoconus progresses during pregnancy. In this report, we present a case of a patient with increased anterior stromal resistance after cross-linking that would favor nonprogression of keratoconus during pregnancy.

Infectious crystalline keratopathy caused by Cladosporium sp. after penetrating keratoplasty: a case report.

Background: Infectious crystalline keratopathy is a rare, progressive infection characterized by the insidious progression of branches and crystalline corneal opacities with minimal or no inflammation. This case report describes the evolution of an infectious crystalline keratopathy caused by Cladosporium sp., which developed after tectonic keratoplasty in a patient with a history of ocular trauma.

Solar retinopathy without abnormal exposure: case report.

Solar retinopathy is photochemical damage to the retina, usually caused, by direct or indirect solar observation resulting from the use of hallucinogenic drugs, mental disorders or during eclipses. There may be a loss of visual acuity. We report the case of a 38-year-old patient who presented with a clinical diagnosis of solar retinopathy in the left eye, no prior history of sun exposure, normal visual acuity and complaints of metamorphopsia.

Idiopathic dilated episcleral vessels (Radius-Maumenee syndrome): case report.

Radius-Maumenee syndrome comprises idiopathic dilated episcleral vessels that are usually associated with glaucoma. The case described herein is of a male patient, 69 years old, with chronic dilation of the episcleral vessels and glaucoma in his left eye, with no history of systemic disease. Visual acuity and fundoscopy were normal in both eyes.

[Prevalence of diabetic retinopathy in patients affected by type 2 diabetes mellitus in the city of Luzerna--SC].

Purpose: To evaluate the prevalence of diabetic retinopathy in patients affected by type 2 diabetes mellitus in the city of Luzerna (SC).

Methods: Cross-sectional study including all individuals with type 2 diabetes mellitus, all ages, both genders, residents in the city of Luzerna. The work analyzed database of 5,350 people from two Family Health Programs, where all city residents are registered.
