PURPOSE: To describe early macular hole (MH) development in rhegmatogenous retinal detachment (RRD) after scleral buckling (SB) based on optical coherence tomography (OCT) findings. METHODS: The medical records and spectral domain OCT images of patients in whom MH developed after RRD repair were evaluated retrospectively. RESULTS: A postoperative MH was detected in five eyes that underwent SB during a 6-year period. All had fovea-off RRD without MH at the time of surgery. OCT showed partial loss of the inner retina with a preserved photoreceptor layer in early postoperative days. On average, 7 days (range,5 to 8 days) after surgery, outer retinal tissues disappeared, resulting in the full-thickness MH. CONCLUSIONS: Serial OCT findings revealed that partial-thickness lamellar holes progressed to full-thickness MHs, which were formed by the degeneration of the outer retina in eyes with preceding loss of the glial cone in the fovea.

We report a case of complete surgical resolution of Valsalva retinopathy that manifested as a premacular hemorrhage involving a membrane followed by a macular hole (MH) resulting from the first vitrectomy. A 20-year-old female patient was referred to our hospital due to sudden vision loss in the left eye. Her best-corrected visual acuity (BCVA) in the left eye was hand motion. Fundus photographs and optical coherence tomography (OCT) revealed a premacular hemorrhage. Nine weeks later, the BCVA in the left eye had returned to 20 / 100 and the premacular hemorrhage had completely resolved, but residual sub-internal limiting membrane deposits and a preretinal membrane were present. The preretinal membrane was removed by core vitrectomy and preretinal membrane peeling, but the foveal deposits could not be excised. Two weeks after the first vitrectomy, the deposits resolved spontaneously, but a full-thickness MH was present. Six months after a second vitrectomy with fluid-gas exchange, the BCVA in the left eye had improved to 20 / 25 and OCT showed that the MH had closed. This case illustrates the possibility of MH formation following vitrectomy for Valsalva retinopathy.

PURPOSE: To discuss the unique morphology and origin of epiretinal proliferation associated with macular hole (EPMH) occasionally observed in full-thickness macular hole (FT-MH) or lamellar hole (LH) and to introduce the perifoveal crown phenomenon encountered when removing this unusual proliferative tissue. METHODS: Sixteen patients showing EPMH in spectral domain-optical coherence tomography were selected from 212 patients diagnosed with MH, LH, FT-MH, impending MH, macular pseudohole, or epiretinal membrane between January 2013 and December 2014. Of the 212 patients included for clinical analysis, 33, 23, 11, 7, and 190 exhibited LH, FT-MH, impending MH, macular pseudohole, and epiretinal membrane, respectively. We reviewed visual acuity, macular morphology, and clinical course. Surgical specimens were analyzed histologically. RESULTS: EPMH presented as an amorphous proliferation starting from the defective inner/outer segment (IS/OS) junction covering the inner macula surface. Among the 16 patients with EPMH, 11 underwent vitrectomy, and all exhibited the intraoperative perifoveal crown phenomenon. EPMH tissue was sampled in three patients, one of whom had more tissue removed than intended and showed delayed recovery in visual acuity. Despite hole closure, IS/OS junction integrity was not successfully restored in four of 11 patients. Five patients were followed-up without surgical intervention. Visual acuity slightly decreased in three patients and did not change in one patient, while the remaining patient was lost during follow-up. Among the three perifoveal crown tissues obtained, two were successfully analyzed histologically. Neither tissue showed positivity to synaptophysin or S-100 protein, but one showed positivity to cytokeratin protein immunohistochemical staining. CONCLUSIONS: EPMH exhibited a distinct but common configuration in spectral domain-optical coherence tomography. An epithelial proliferation origin is plausible based on its configuration and histological analysis. Perifoveal crown phenomenon was observed when removing EPMH during vitrectomy.
