Prognostic Factors for Visual Outcome in Purtscher Retinopathy

Systematic review of Purtscher’s and Purtscher-like retinopathies

“…Unlike other studies that discussed prognostic factors for PuR, 18 we did not find any fundoscopic or angiographic sign of prognostic value for VA improvement.…”

“…Poor prognostic factors for visual improvement such as choroidal hypoperfusion, optic disc swelling, 7 or massive Purtscher flecken 18 were not statistically significant, but only a small number of cases presented with these findings.…”

“…Some studies required translation. 15,20,[33][34][35][36][37][38][39][40] Quality evaluation graphs were made using Review Manager v5 (Cochrane Collaboration, Oxford, UK). Data were collected as part of the quality evaluation process: description of the study design, description of patient demographics, diagnostic criteria used to define PuR, VA testing method, description of results, follow-up examinations made by an ophthalmologist, and followup duration.…”

Retinopatia de Purtscher e Purtscher-like

“…Poderia ser embolia gordurosa, ou relacionada à liberação, na circulação sistêmica, de enzimas proteolíticas procedentes do pân-creas inflamado (16,17) . Tem-se proposto que a agregação leucocitária induziria a ativação da cascata do complemento.…”

“…De todas as formas, o mecanismo final comum é a alteração da permeabilidade microvascular retiniana secundária a uma micro-oclusão capilar, com lesão endotelial hipertensiva (16) .…”
