To describe the resolution of an impending macular hole in myopic foveoschisis.
Methods
A 75-year-old man with retinal schisis and macular foveoschisis developed the foveal detachment and progressed to an impending macular hole. After 16 months later, retinal schisis decreased and the outer lamellar macular hole(OLMH) was also closed. The improving process of OLMH was observed by optical coherence tomography (Cirrus spectral-domain OCT).
Results
During the initial stages of macular hole formation due to myopic foveoschisis, a columnar foveal detachment, with destroyed inner segment/outer segment junction line, was observed. Twelve months later, the concrete columnar structure had shortened and formed a dome-shaped structure under the roof. The retinal schisis between the inner and outer retina also decreased. Sixteen months after the initial visit, an OLMH was closed and the stretching of the outer plexiform layer was significantly improved and the foveal anatomic feature was nearly recovered. But an interruption of the IS/OS junction line was remained. The final BCVA was 0.76 logMAR unit, had better vision
Conclusion
These OCT findings suggested that the cone-shaped structure was pulled from the outer retina by anteroposterior vitreous traction. This case may cause a progressively OLMH formation, and finally made a complete resolution and closed the hole. The natural course of myopic traction maculopathy varies, and commonly eyes with more extensive macular retinoschisis tend to progress more commonly. These findings can be used to determine the factors correlated with the progression or resolution. |
