Abstract
Purpose :
To assess if it is possible to identify the presence and types of staphyloma in a Spanish high myopia (HM) sample using large frames obtained with a high definition Swept-Source Optical Coherence Tomography (SS-OCT) imaging tool.
Methods :
An observational prospective study was carried out recruiting consecutive HM patients seen in an ophthalmological clinic excluding those with any other retinal complication. At least two 16 mm HD Spotlight single scans were performed using SS-OCT Plex Elite 9000 (Carl Zeiss Meditec, Jena, Germany). Other data were gathered including age, axial length (AL) and visual acuity (VA). Ohno-Matsui criterion was followed to classify the type of staphyloma.
Results :
A total of 179 eyes of 100 patients were recruited (age: 51.4±16.8 years, 68.7% women, AL:28.8±2.33 mm). One hundred and twenty-three eyes (68.7%) were identified to have a staphyloma. Frequency of observation for each type was: wide macular (47.2%), narrow macular (17.9%), nasal (13%), peripapillary (8.1%), inferior (8.1%) y other types (5.7%). Patients with staphyloma were older, had worser VA and longer AL (p<0.001).
Conclusions :
SS-OCT shows up as a novel and potent tool to detect staphyloma, which is a quite prevalent alteration in a Spanish HM sample. Patients with staphyloma were older, had worser VA and longer AL
