To describe the features and incidence of epiretinal traction and relatedretinal damage in degenerative myopia.
Consecutive observational case series.
We retrospectively reviewed medical records and optical coherence tomographyfindings of 218 eyes with high myopia of 121 consecutive patients to detectthe incidence and features of epiretinal traction–related macular damage.The degree of myopia ranged from –8 to –26 spherical equivalent(mean ± SD, –16.93 ± 5.74). Mean ± SD axial lengthwas 29.75 ± 2.12 mm. Excluding eyes with possibly confounding features,125 eyes were analyzed.
Main Outcome Measure
Detection of epiretinal traction and related macular damage.
Epiretinal traction was found in 58 (46.4%) of 125 eyes and retinaldamage, in 43 eyes (34.4%). Macular retinoschisis was the most frequent formof macular damage (25 eyes [58%]), followed by retinal thickening, lamellarhole, and shallow retinal detachment.
Epiretinal traction is a frequent finding in degenerative myopia and,particularly if associated with the presence of staphyloma, can generate aform of macular damage unique to eyes with high myopia. This damage can affectup to one third of these eyes and should be considered as a separate causeof visual loss easily detected by optical coherence tomography at its earlystages.
