ObjectiveFovea-involving subretinal haemorrhage is challenging to manage with uncertain visual outcomes. We reviewed outcomes of patients with fovea-involving macular haemorrhage treated with pars plana vitrectomy (PPV) and subretinal tissue plasminogen activator (tPA) with pneumatic displacement.Methods and AnalysisThis is a retrospective interventional case series. All patients with submacular haemorrhage who underwent PPV with subretinal tPA injection were included. Reasons for exclusion encompassed patients who underwent intravitreal tPA injection in the office without surgery, insufficient follow-up or documentation. Primary outcomes of interest were postoperative visual acuity (VA) at month 1 and 3. Secondary outcomes were median VA at month 3 by location of haemorrhage and underlying diagnosis.ResultsThirty-seven total patients were included. The mean age was 68.2 years, with 54.1% (20/37) females. The most common aetiology was exudative macular degeneration (43.2%), followed by undifferentiated choroidal neovascularisation (CNV) (18.9%), polypoidal choroidal vasculopathy (18.9%), traumatic CNV (10.8%), macroaneurysm (5.4%) and proliferative diabetic retinopathy (2.7%). Median preoperative VA was 20/2000, postoperative month 1 was 20/347 (pConclusionsPPV with subretinal tPA injection and pneumatic displacement of submacular haemorrhage offers modest visual recovery for a diverse group of patients. Location of haemorrhage or specific diagnosis may not predict outcome.

Purpose: To report a case of release of vitreomacular traction (VMT) in a patient with a full thickness macular hole (FTMH) immediately following pneumatic vitreolysis (PV) combined with head bobbing movements. Methods: A 71-year-old female with VMT and an FTMH presented with blurred vision for 2 months to the level of 20/400. At her 1-month follow-up visit, PV was performed using C3F8 gas and she was instructed to perform the drinking bird technique for ten minutes. Results: Optical coherence tomography performed ten minutes after PV with head bobbing showed VMT release and a smaller FTMH. Visual acuity improved to 20/150 immediately afterwards and to 20/80 two months later. Conclusions: Using the drinking bird technique for a continuous period of time immediately following PV may encourage rapid VMT release. PV may be a feasible option for patients with VMT and FTMH who do not want surgery.

Purpose To review the clinical radiographic and histopathologic findings associated with orbital glial heterotopia. Methods A literature search in PubMed and Scopus was performed to include all articles published in English between 1980 and January 1, 2019. A case series including 29 case reports of 29 patients, as well as the authors' 2 cases, were considered in the literature review. Results The majority of the cases had onset of symptoms (86%) and age at presentation (71%) before 5 years of age. The most common presenting symptoms and signs were swelling (45%), strabismus (32%), and proptosis (26%). The most common lesion locations described were inferolateral (19%) or primarily posterior orbital or apical (19%). The most common findings associated with orbital glial heterotopia were microphthalmia (10%) and anophthalmia (6%); however, the majority did not have systemic abnormalities (71%). The most common imaging modality was CT scan (71%). Diagnosis was made with histologic analysis in all cases, and confirmed after subtotal resection (35%), total resection (39%), or incisional biopsy (26%). The majority of the cases report no growth on repeat imaging, with only 3 reports of recurrence. Conclusions Glial heterotopia in the orbit is a rare clinical entity most commonly presenting in children. We present 2 cases of orbital glial heterotopia in adults, with a literature on these lesions in both the pediatric and adult populations. Surgeons and pathologists should be aware of this atypical presentation in adulthood. Biopsy is required for diagnosis but is not without risk. Prognosis is generally favorable.Orbital glial heterotopia, commonly considered a rare congenital lesion generally presenting in children, may first become symptomatic in adulthood. Biopsy is required for diagnosis, with symptoms and prognosis dependent on location and growth of the lesion.
