Case 1
A 58-year-old black man presented to the Nova Southeastern University Eye Care Institute for an evaluation of recently decreased vision in the right eye. He stated that he noticed a progressive and drastic decrease in vision over the prior 6 months in that eye. According to the patient, his last eye examination was 7 years earlier. He was wearing rigid gas-permeable contact lenses at the time of the examination.
His medical history was remarkable for type 2 diabetes mellitus for which he was
Discussion
Chorioretinal changes associated with degenerative myopia have been attributed to a congenital-derived weakness of the sclera.1, 2, 3, 4, 5 This structural defect leads to the progressive stretching of the sclera and development of a posterior staphyloma. Accompanying complications of the degenerative myopic ectasia may include atrophy of the choroid and its capillary network, Bruch’s membrane fractures, posterior retinal detachment, choroidal neovascularization, and foveal hemorrhages.

Conclusion
MTM is a recently characterized maculopathy included in the spectrum of myopic degenerative disorders. It may be difficult to appreciate on biomicroscopy and can present with a variety of visual deteriorations. TDOCT or SDOCT may facilitate the diagnosis of MTM in patients with a high level of myopia and a posterior staphyloma. Detecting this condition early, and referring the patient to a retinal specialist for evaluation and treatment when appropriate, may prevent further vision loss,
