MACULAR DETACHMENT ASSOCIATED WITH INTRACHOROIDAL CAVITATION IN NONPATHOLOGICAL MYOPIC EYES.

PURPOSE: To report the characteristics of a macular detachment associated with peripapillary intrachoroidal cavitation (ICC) and the outcomes of vitrectomy.

METHODS

The medical records of 69 eyes of 61 patients who underwent vitrectomy for macular detachment or macular retinoschisis but without vitreomacular traction or optic disc pit were reviewed. Optical coherence tomography was used to determine the morphology of the ICC. The outcomes of vitrectomy including the creation of a posterior vitreous detachment and internal limiting membrane peeling were evaluated.

RESULTS

An ICC was detected in 3 of 3 eyes without pathologic myopia but none in 66 eyes with pathologic myopia (P < 0.0001). Myopic peripapillary conus was present in all 3 eyes, tilted disc in 2 eyes (67%), posterior staphyloma in 1 eye (33%), and no preoperative posterior vitreous detachment in all eyes. Optical coherence tomography detected a connection between the vitreous cavity and the ICC in two eyes with pit-like splitting and between the subretinal space and the ICC in two eyes. The macular detachment was resolved 5 months to 6 months postoperatively with improvement of vision.

CONCLUSION

A macular detachment with ICC can be present in nonpathological myopic eyes. Vitreous surgery to create a posterior vitreous detachment with internal limiting membrane peeling may help resolve the macular detachment.
