Macular hole formation and spontaneous closure after vitrectomy for rhegmatogenous retinal detachment documented by spectral-domain optical coherence tomography: Case report and literature review

Ultrasound in ocular oncology: Technical advances, clinical applications, and limitations

Due to its accessibility and ability for real-time image acquisition of ocular structures, ultrasound has high utility in the visualization of the eye, especially in ocular oncology. In this minireview, we summarize the technical rationale and applications of ultrasound modalities, A-scan, B-scan, high-frequency ultrasound biomicroscopy (UBM), and Doppler measurement. A-scan ultrasound uses a transducer of 7-11 MHz, making it useful for determining the echogenicity of ocular tumors (7-8 MHz) and measuring the axial length of the eye (10-11 MHz). B-scan ultrasound operates at 10-20 MHz, which can be used for measuring posterior ocular tumors while UBM operates at 40-100 MHz to evaluate anterior ocular structures. Doppler ultrasonography allows for the detection of tumor vascularization. While ultrasonography has numerous clinical applications due to its favorable penetration compared with optical coherence tomography, it is still limited by its relatively lower resolution. Ultrasound also requires an experienced sonographer due to the need for accurate probe localization to areas of interest.

Macular holes following vitrectomy for rhegmatogenous retinal detachment: epiretinal proliferation and spontaneous closure of macular holes

PURPOSE

To describe the characteristics and management of full-thickness macular holes (MHs) that develop after pars plana vitrectomy for rhegmatogenous retinal detachment (RD).

METHODS

Retrospective, interventional, consecutive case series. Patients who developed secondary full-thickness MHs after prior pars plana vitrectomy for RD over a 6-year period were included. The main outcome measures included optical coherence tomography (OCT) findings and the clinical course of full-thickness MHs.

RESULTS

A total of 11 eyes of 11 consecutive patients were included in the study. The mean age of the patients was 58.8 years (range, 47-70 years). The median time between RD repair and MH diagnosis was 36 months (range, 1 month-11 years). The fovea was attached to 10 eyes (91%) at the time of RD repair. OCT demonstrated epiretinal proliferation (EP) at the hole margin in 10 eyes (91%). MH spontaneously closed in 7 eyes (63%) but reopened in 5 eyes. A total of 7 eyes (63%) required a vitrectomy to repair the MHs. All MHs were closed at the last follow-up visit.

CONCLUSION

Full-thickness MHs after pars plana vitrectomy for RD have features that are distinct from that of typical idiopathic MH. The presence of EPs is common, and MHs are prone to spontaneous closure and reopening. These findings suggest that EP may be associated with spontaneous hole closure and that long-term follow-up is necessary even if the MHs close spontaneously.

Spontaneous disappearance and recurrence of impending macular hole: a case report

Background

There have been several reports of spontaneous closure and reopening of a macular hole, however, in most of those cases, it was observed in eyes post vitrectomy. Here, we report a case of multiple episodes of spontaneous disappearance and recurrence of impending macular hole (stage 1B macular hole) with no history of previous surgery.

Case presentation

A 76-year-old Japanese man presented with a primary complaint of reduced visual acuity in his right eye. On initial examination, the visual acuity in his right and left eye was 0.4 and 0.01, respectively. He had previously been diagnosed as having macular degeneration of unknown origin in his left eye. Optical coherence tomography imaging confirmed vitreomacular traction and impending macular hole in his right eye. After a 1-week follow-up period, posterior vitreous detachment was detected, and the impending macular hole appeared to be resolved. Two months later, the impending macular hole had completely disappeared and his visual acuity had improved to 0.9. Six months later, he again noticed decreased vision in his right eye. An examination revealed that his visual acuity had dropped to 0.4, and there was a recurrence of impending macular hole. An optical coherence tomography examination showed no definitive findings of vitreous traction, and, 1 month later, spontaneous disappearance was observed again and his visual acuity improved to 0.7.

Conclusions

In this case, both the initial onset and the recurrence involved impending macular hole, however, the optical coherence tomography findings differed at each examination. These findings suggest that some causes other than vitreous traction were responsible for both the spontaneous disappearance and recurrence of the impending macular hole in this present case.

Spontaneous Closure of Full-Thickness Macular Hole With Epiretinal Membrane in Vitrectomized Eyes: Case Series and Review of Literature

The authors describe three vitrectomized eyes that each subsequently developed a full-thickness macular hole (FTMH) that then spontaneously closed and summarize the current literature reporting these rare events. Clinical history, imaging, and course of three patients were reviewed and compiled. All three cases in this series developed a FTMH less than 7 months following vitrectomy (for epiretinal membrane [ERM], n = 1) and retinal detachment (n = 2) that demonstrated spontaneous resolution within 2 months of symptom onset, without intervention. All three vitrectomized eyes had small holes ranging from 48 µm to 189 µm in inner opening diameter and had an ERM or lamellar hole epiretinal proliferation documented before FTMH formation. These cases demonstrate that spontaneous closure of FTMH is possible in vitrectomized eyes with small holes despite the presence of ERM. On reviewing similar cases reported in the current literature, the presence of a mild ERM with a small FTMH may even be a favorable characteristic for spontaneous closure.
