Total retinal detachment and contractile movement of the disc in eyes with morning glory syndrome

Rapid Resolution of Serous Retinal Detachment in Morning Glory Disc Anomaly With Oral Acetazolamide Treatment

Morning glory disc anomaly is a rare congenital anomaly affecting the optic disc and is frequently associated with retinal detachment. This report presents a unique case of a 10-year-old boy with morning glory disc anomaly and serous retinal detachment, treated with oral acetazolamide. Remarkably, half of the retina exhibiting bullous detachment was reattached leading to full recovery of vision within a few days after starting acetazol-amide treatment. There was no recurrence after discontinuation of medication. Oral acetazolamide can be considered an alternative treatment option for retinal detachment associated with morning glory disc anomaly of non-rhegmatogenous origin.

MANAGEMENT OF RETINAL DETACHMENT ASSOCIATED WITH MORNING GLORY SYNDROME USING THE HUMAN AMNIOTIC MEMBRANE

PURPOSE

This case report describes an innovative procedure for addressing retinal detachment in patients with morning glory syndrome.

METHODS

An 18-year-old woman with unilateral morning glory syndrome complicated by macula-off retinal detachment without any visible peripheral retinal breaks underwent three corrective surgeries. In the first surgery, a 25-gauge pars plana vitrectomy with a 3-mm human amniotic membrane patch positioned on the optic disc and gas endotamponade was performed. When the gas reabsorbed, inferior retinal detachment recurred, and a second vitrectomy with silicone oil endotamponade was conducted. At three months, the retina was still attached under the silicone oil, so the oil was removed. At the second follow-up, retinal detachment had recurred, and a third vitrectomy with a larger amniotic patch and silicone oil endotamponade was performed.

RESULTS

Three months following the last surgery, the subretinal fluid had totally reabsorbed, and the retina was completely attached. The best-corrected visual acuity was 20/100.

CONCLUSION

To the best of our knowledge, the first description of a human amniotic patch associated with vitrectomy in morning glory syndrome complicated with retinal detachment is described. Using human amniotic membranes, positioned onto the optic nerve, and silicone oil endotamponade could be useful for morning glory syndrome complicated by retinal detachment.

Recurrent proliferative vitreoretinopathy in a patient with morning glory syndrome and intellectual disability

Purpose

To report a case of morning glory syndrome (MGS) with retinal detachment, in whom unusually severe proliferative vitreoretinopathy (PVR) developed after surgery.

Observations

A 6-year-old boy with intellectual disability underwent vitrectomy for retinal detachment associated with MGS in the left eye. Vitrectomy was performed five times. C₃F₈ gas tamponade was used for the first and second surgeries. However, the retina developed PVR with a nearly 360-degree giant retinal tear after the second surgery. The third surgery required 360-degree retinotomy, followed by short-term perfluoro-n-octane (PFO) tamponade, which was removed ten days later. During the fourth surgery, the retina was found to be flipped over in a funnel-shape on the retinal pigment epithelium under the PFO. Silicone oil (SO) tamponade was used. During the fifth surgery, the retina was flipped over under the SO again. We found that the patient shook his head rapidly and vigorously while crying.

Conclusions and importance

We speculate that excessive head shaking associated with the patient's intellectual disability induced an unusual shape of the retina under PFO or SO. Although difficult to achieve, postoperative resting seems important in preventing such complications in intellectually disabled patients with retinal detachment.

•

Severe proliferative vitreoretinopathy developed after surgery for retinal detachment associated with morning glory syndrome.

•

The retina was flipped over under perfluorocarbon liquid or silicone oil.

•

Such unusual complications may have occurred by the excessive head shaking associated with the patient's intellectual disability.

Internal limiting membrane packing for treatment of morning glory syndrome with rhegmatogenous retinal detachment

Purpose

Observations

Conclusions and importance

•

Morning Glory syndrome (MGS) is a rare congenital optic disc abnormality.

•

We report a case of MGS combined with rhegmatogenous retinal detachment (RRD) in which the contractile movement of the retinal hole was observed.

•

This case is the first to report the successful treatment of a retinal hole in a MGS patient by internal limiting membrane tamponade combined with autologous blood coverage.

Clinical and Echographic Features of Morning Glory Disc Anomaly in Children: A Retrospective Study of 249 Chinese Patients

Purpose

To report the clinical and echographic features, the prevalence of retinal detachment (RD), and associated visual acuity in a cohort of pediatric patients with morning glory disc anomaly (MGDA).

Methods

This was a retrospective review of 249 pediatric patients with MGDA (271 eyes) seen at the Dept. of Ophthalmology, Xinhua Hospital. Their medical records were reviewed for demographic data and ocular and systemic findings. The maximal depth and width of the cavity were measured using standardized echographic images. The ratios of cavitary depth to axial length, cavitary depth to maximal cavitary width, and the product of cavitary depth and width were calculated and used to indicate the relative size of the excavation. The clinical and echographic findings were correlated with visual acuity and the occurrence of RD of the patient.

Results

The relative size of the excavation and the presence of RD were positively associated with increased risk of poor vision (p < 0.05). The presence of persistent fetal vasculature was not associated with the risk of RD and poor vision. The ratio of cavitary depth to axial length more than or equal to 0.25 conferred an increased risk of RD (OR, 2.101; 95% CI, 1.469–3.003).

Conclusions

Clinical and echographic features of MGDA may be used in predicting the risk of RD. Measuring the relative size of excavation via echography may guide the follow-ups and assist in the early diagnosis of RD.
