Terson syndrome refers to intraocular haemorrhage that occurs due to subarachnoid bleeding associated with an acute increase in intracranial pressure. No previous study has reported a delayed macular hole (MH) secondary to Terson syndrome. A 17-year-old boy visited our department and presented with vitreous bleeding and a history of subarachnoid haemorrhage. Sub-internal limiting membrane (ILM) haemorrhage with ILM detachment and intraretinal haemorrhage were detected during pars plana vitrectomy. Additionally, a delayed MH was detected 1 week after the surgery. There was no sign of MH closure during a 2-month follow-up. Subsequently, an MH massage was performed to close the MH. Our findings suggest that a delayed MH can occur secondary to Terson syndrome. Elevated hydrodynamic pressure and hydrostatic pressure, which are caused by sub-ILM and intraretinal haemorrhages of the fovea, contribute to the formation of an MH. Additionally, ILM peeling may cause damage to the macula and facilitate the formation of MHs. Although the MH may close by itself, early surgical intervention is recommended when there is no sign that the MH will close spontaneously because a prolonged MH can lead to retinal damage.

Purpose: To examine the quantitative measurements of OCTA in children with amblyopia using the meta-analysis methodology. Methods: PubMed, Embase, and Cochrane library were searched for available papers up to March 2021. Weighted mean differences (WMD) were used to compare the retina parameters between the eyes with amblyopia and the contralateral eyes or healthy control eyes. Results: Twelve studies were included. When considering the parafovea, the microvessel density was reduced in amblyopic eyes compared with healthy control eyes in the superficial capillary plexus (SCP) in 6 × 6 volume scan (WMD = -2.12, 95%CI: -3.24, -0.99) but not SCP in 3 × 3 volume scan (WMD = -1.43, 95%CI: -2.96, 0.11). In the deep capillary plexus (DCP), amblyopia did not decrease vessel density in the 6 × 6 volume scan (WMD = -2.22, 95%CI: -5.86, 1.42; I 2 = 79.6%, P = 0.008), but a difference was observed in the whole eye 3 × 3 (WMD = -1.95, 95%CI: -3.23, -0.67; I 2 = 27.5%, P = 0.252). There were no significant differences in the foveal avascular zone area and foveal thickness between amblyopic eyes and healthy control eyes. There were no significant differences in microvessel density, foveal avascular zone area, and foveal thickness between amblyopic eyes and fellow eyes. Conclusion: According to OCTA, amblyopic eyes had lower vessel density in parafoveal SCP and DCP compared with healthy control eyes, but not compared with fellow eyes. There were no significant differences regarding the foveal avascular zone area and foveal thickness between amblyopic and non-amblyopic eyes.

OBJECTIVE: To describe ocular findings in 3 cases of solar retinopathy using high definition, spectral domain optical coherence tomography (SD-OCT) and review the literature for optical coherence tomography (OCT) characteristics associated with worse vision.
METHODS: Case series and retrospective review of clinical features and Spectralis SD-OCT (Heidelberg Engineering, Vista, California, United States of America). A literature review of OCT findings in cases of solar retinopathy reported on MEDLINE was also performed and analyzed.
RESULTS: Six eyes of 3 patients with solar retinopathy revealed significant foveal pathology. Visual acuity ranged from Snellen 20/30 to 20/50. High definition SD-OCT demonstrated defects at the level of the inner and outer segment junction of the photoreceptors as well as in the inner high reflective layer. There was a significant correlation between chronic disruption of the inner photoreceptor junction with worse vision based on the current case series and literature review.
CONCLUSIONS: Screening patients with exposure to central foveal damage from solar retinopathy with high definition SD-OCT improves diagnosis and assessment of photoreceptor damage and vision loss.
