Intensive Urbanization, Urban Meteorology and Air Pollutants: Effects on the Temperature of a City in a Basin Geography.

A qualitative study of thermal transfers is carried out from a record of measurements (time series) of meteorological variables (temperature, relative humidity and magnitude of wind speeds) and pollutants (PM, PM and CO) in six localities located at different heights in the geographic basin of Santiago de Chile. The measurements were made in two periods, 2010-2013 and 2017-2020 (a total of 2,049,336 data), the last period coinciding with a process of intense urbanization, especially high-rise construction. The measurements, in the form of hourly time series, are analyzed on the one hand according to the theory of thermal conduction discretizing the differential equation of the temporal variation in the temperature and, on the other hand, through the theory of chaos that provides the entropies (S).

Bilateral retinal vasculopathy associated with autosomal dominant dyskeratosis congenita.

Purpose: To report a case of autosomal dominant dyskeratosis congenita (AD-DC) complicated by bilateral retinal vasculopathy and proliferative retinopathy with vitreous hemorrhage in the right eye, in the absence of pancytopenia.


Methods: We report a 32-year-old woman who presented with floaters in her right eye. She underwent complete ophthalmic examination and fundus fluorescein angiography.

Factors determining visual outcome in endogenous Candida endophthalmitis.

Purpose: To determine factors affecting the visual outcome of eyes with endogenous Candida endophthalmitis.

Methods: Retrospective cohort study of 44 eyes from 36 patients diagnosed with candida endophthalmitis at 2 tertiary referral uveitis centers. Outcome measures included the development of retinal detachment and the occurrence of visual loss (visual acuity of <20/40) and severe visual loss (visual acuity of ≤ 20/200).

Intravitreal triamcinolone acetonide as adjunctive treatment with systemic therapy for uveitic macular edema.

Purpose: To report the outcome of a single intravitreal triamcinolone acetonide (IVTA) injection as an adjunctive treatment with systemic medication for refractory uveitic cystoid macular edema (CME).

Methods: This was a retrospective, noncomparative, interventional case series. Medical records of 25 patients (35 eyes) with quiescent uveitic CME who were treated with oral immunosuppressive therapy and underwent 4 mg/0.

Oral moxifloxacin and topical amikacin for Mycobacterium abscessus keratitis after laser in situ keratomileusis.

We report a case of Mycobacterium abscessus keratitis after elective laser in situ keratomileusis in a 19-year-old woman. The infection started 3 weeks after uneventful surgery, and the patient received multiple antimicrobial treatments without response. A corneal scrape isolate showed an acid-fast bacterium that was subsequently confirmed by culture to be M abscessus.

Pole to pole intraocular transit of tarantula hairs-an intriguing cause of red eye.

This intriguing case report provides novel images and a description of the anterior and rarer posterior segment findings seen in ocular inflammation associated with tarantula spider hair exposure. We present an interventional case report of a 9-year-old boy who presented with a red, sore eye. Slit lamp examination revealed right eye injection, multiple small hairs at differing levels of the cornea with associated opacities and inflammation within the anterior and posterior segments of the eye.

Intraocular methotrexate in the treatment of uveitis and uveitic cystoid macular edema.

Objective: A pilot study to evaluate the use of intravitreal methotrexate (MTX) for the treatment of uveitis and uveitic cystoid macular edema (CME).

Design: Prospective, consecutive, interventional case series.

Participants: Fifteen eyes of 15 patients with a unilateral exacerbation of noninfectious intermediate, posterior uveitis, or panuveitis and/or CME such that visual acuity (VA) was 20/40 or worse, together with a history of increased intraocular pressure (IOP) in response to corticosteroid administration.

Azathioprine in the management of autoimmune uveitis.

Purpose: To evaluate the role of azathioprine as an immunosuppressive for steroid-resistant autoimmune uveitis (AIU).

Methods: Patients using oral prednisolone for active AIU without clinical response were recruited. A standard protocol of oral prednisolone and azathioprine was used.

[Role of Azathioprine in steroid resistant non infectious ocular inflammatory diseases].

Background: Topical and systemic steroids are the first line of treatment of non infectious inflammatory ocular disease. Immunosuppresants are reserved as a second line treatment.

Aim: To evaluate the role of Azathioprine (AZA) as a coadyuvant immunosuppressive treatment for non infectious ocular inflammatory diseases (OIDs) resistant to systemic steroid therapy in a retrospective, noncomparative interventional case series.

[Carotid cavernous fistula: the importance of its opportune diagnosis and treatment to prevent blindness].

A carotid cavernous fistula is an abnormal communication between a branch of the carotid artery and the cavernous sinus generating an arteriovenous fistula that can cause severe ocular damage. We hereby report two cases of carotid cavernous fistulas. A 69-year-old male with a 2-month history of right eyelid swelling and red eye aggrarated by diplopia, exophthalmus, and limitation of ocular movements one week before consulting.
