Optical coherence tomography findings in myopic traction maculopathy.

OBJECTIVE: To describe the features and incidence of epiretinal traction and related retinal damage in degenerative myopia. DESIGN: Consecutive observational case series. METHODS: We retrospectively reviewed medical records and optical coherence tomography findings of 218 eyes with high myopia of 121 consecutive patients to detect the 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 length was 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. RESULTS: Epiretinal traction was found in 58 (46.4%) of 125 eyes and retinal damage, in 43 eyes (34.4%). Macular retinoschisis was the most frequent form of macular damage (25 eyes [58%]), followed by retinal thickening, lamellar hole, and shallow retinal detachment. CONCLUSIONS: Epiretinal traction is a frequent finding in degenerative myopia and, particularly if associated with the presence of staphyloma, can generate a form of macular damage unique to eyes with high myopia. This damage can affect up to one third of these eyes and should be considered as a separate cause of visual loss easily detected by optical coherence tomography at its early stages.

Cataracts associated with posterior segment surgery.

Although cataract is widely described among the complications of vitrectomy, the precise relationship between vitrectomy and the development of lens opacity is not completely understood. This article presents an extensive literature review and the authors' personal experience with this complication.

Role of OCT in the diagnosis and follow up of diabetic macular edema.

The aim is to present, along with a brief literature review, the results of OCT scan in eyes with diabetic macular edema (DME), as well as examples of the utility of OCT for different therapeutic approaches. One-hundred and thirty-six eyes with diabetic retinopathy were analyzed with OCT to explore the different patterns of DME. Some eyes with DME were studied with OCT pre and postoperatively to determine the efficacy of photocoagulation and vitrectomy to restore a normal macular profile. Sixty-eight eyes with a central foveal thickness of 200 mu or more were considered "edematous". Three different patterns of DME were recognized and analyzed: macular thickening, cystoid macular edema and shallow retinal detachment. The change in macular profile and internal retinal structure after laser or surgical treatment are well visible with OCT. OCT contributes in understanding the anatomy of DME and the intraretinal damage and seems to be the technique of choice for the follow-up of macular edema. We think that this tool should always be used in monitoring the effect of therapies in future studies.

OCT in the monitoring of visual recovery after uneventful retinal detachment surgery.

The aim is to describe 5 cases of unexplained visual impairment after uneventful episcleral surgery associated with submacular lesions occurring post-operatively (bleb-like syndrome). The 5 cases were followed with biomicroscopy and OCT for up to 6 months. At biomicroscopy the 5 eyes presented no visible abnormalities or a yellow subfoveal dot. OCT demonstrated the presence of isolated or multiple subfoveal or submacular blebs. Some cases experienced partial or total slow spontaneous resolution, while other blebs remained stable for months or slightly enlarged. In conclusion, OCT can play an important role in the follow up of patients with unexplained visual impairment after episcleral surgery and diagnose the presence of small subfoveal shallow retinal detachments persistent for months after surgery. We think that OCT should be routinely considered in the follow-up of these patients.
