Choroidal detachment. Epidemiological and ultrasound characteristics in an Ophthalmological center in Mexico City

Background: To describe the ultrasound features and disease history of patients with a diagnosis of choroidal detachment evaluated in the Ultrasound Department of the Instituto de Oftalmología “Fundación Conde de Valenciana IAP” of Mexico City from January 2015 to December 2017. Design: Observational, descriptive and retrospective. Methods: All the medical records with a diagnosis of choroidal detachment by ultrasound were analyzed. Exclusion criteria were missing and/or incomplete records. The information obtained was classified by causal disease, type, shape and extension of the choroidal detachment. Results: One hundred and forty-one patients were studied (89 [63.1%] men and 52 [36.9%] women). The average age was 52.92 years in men and 60.98 years in women. Cases related to inflammatory diseases were the most common (76 cases [53.9%]). A total of 102 cases (72.3%) showed a serous choroidal detachment. From all the serous choroidal detachments, 74 cases (52.5%) were observed as flat elevations and 87 cases (61.7%) affected more than six meridians. The average intraocular pressure was 7.63 mmHg. Conclusions: Ultrasound characteristics (shape, type and extension) of choroidal detachments depend on the cause. Flat detachments (mostly inflammatory) show a serous content and extend less than 6 dia-meters, while hemorrhagic detachments (mainly traumatic) tend to be dome-shaped and have a greater extension.
