Early-Phase Perceptions of COVID-19's Impact on Ophthalmology Practice Patterns: A Survey from the Pan-American Association of Ophthalmology.

Purpose: The COVID-19 pandemic affected medical practice worldwide due to interventions to prevent spreading. Its effect on ophthalmology practices in Latin America has not yet been explored. We aimed to assess the perceptions about the pandemic from countries' ophthalmological national and subspecialty retina societies affiliated to the Pan-American Association of Ophthalmology (PAAO).

Intravitreal bevacizumab monotherapy in myopic choroidal neovascularisation: 5-year outcomes for the PAN-American Collaborative Retina Study Group.

Purpose: To report the long-term anatomical and visual outcomes of intravitreal bevacizumab (IVB) monotherapy in naive choroidal neovascularisation (CNV) caused by myopia.

Methods: Retrospective analysis of naive CNV secondary to myopia that underwent antivascular endothelial growth factor monotherapy was performed. Collected data included demographic details, clinical examination details including visual acuity at presentation and follow-up with imaging and treatment details.

Mycophenolate Mofetil Therapy in Refractory Inflammatory Eye Disease.

Purpose: To study the efficacy and incidence of treatment-related side effects of mycophenolate mofetil (MMF) therapy in patients with noninfectious inflammatory eye diseases.

Methods: Retrospective cohort study of 27 Chilean patients treated for noninfectious inflammatory eye diseases using MMF therapy over a 10-year period. Main outcome measures were: ability to control ocular inflammation and to taper prednisone to ≤10 mg daily (treatment success); incidence of treatment-related side effects.

Residual internal limiting membrane after epiretinal membrane peeling: results of the Pan-American Collaborative Retina Study Group.

Purpose: To determine the degree of residual internal limiting membrane (ILM) after idiopathic epiretinal membrane (ERM) peeling and the usefulness of staining with brilliant blue G.

Methods: A prospective, multicenter, observational study of 98 eyes undergoing pars plana vitrectomy and membrane peeling for idiopathic ERM. All eyes underwent core vitrectomy (20, 23, or 25 gauge) followed by intravitreal triamcinolone to verify that the posterior hyaloid had been removed.

Endophthalmitis after pars plana vitrectomy: results of the Pan American Collaborative Retina Study Group.

Purpose: To determine the incidence of endophthalmitis after 20-, 23-, and 25-gauge pars plana vitrectomies (PPVs).

Methods: Retrospective comparative case series of consecutive patients who underwent 20-, 23-, or 25-gauge PPV at 11 centers from Latin America between 2005 to 2009. Pars plana vitrectomy cases were identified through a search of the billing records of each institution.

Comparison of the clinical efficacy of two different immunosuppressive regimens in patients with chronic vogt-koyanagi-harada disease.

Purpose: To prospectively compare 2 immunosupressive regimens in patients with active Vogt-Koyanagi-Harada disease in spite of systemic glucocorticoid treatment.

Methods: Forty-four patients were diagnosed between 1998 and 2005. Twenty-one developed chronic intraocular inflammation in spite of glucocorticoid treatment and were randomized to receive either prednisone and azathioprine (AZA) (n = 12) or prednisone and cyclosporine (CyA) (n = 9).
