This anatomical peculiarity is of growing interest due to its impact on vision and the therapeutic challenges it presents. Despite research advances, gaps persist, requiring thorough exploration to better understand this rare condition. We present the case of a young girl. Observation: A 7-year-old girl presented with persistent deterioration of vision in the right eye since birth. Visual acuity was counting fingers at 2 meters in the right eye and 10/10 in the left eye. Biomicroscopy was normal in both eyes, and fundus examination revealed a funnel-shaped excavation at the optic disc of the right eye, associated with central glial proliferation, thin blood vessels in a radial distribution, and atrophy of the neuroretinal rim. Additional tests confirmed the diagnosis of isolated unilateral Morning Glory Syndrome in the right eye. Combined treatment included appropriate optical correction and functional rehabilitation. Regular ophthalmological follow-up over a one-year period was established to monitor visual acuity evolution, optic disc stability, and detect any potential complications. The reserved prognosis was marked by the absence of ocular complications and maintenance of initial visual acuity in the right eye. Conclusion: The positive response to management underscores the importance of an integrated approach, early diagnosis, therapeutic adherence, and personalized strategies.展开更多

These deformations involve the size, shape, color, and vessels of the optic disc. Although often asymptomatic, these anomalies can impact the visual development of the child, underscoring the importance of a thorough fundus examination for early detection and appropriate medical follow-up. We present two cases of congenital optic disc anomalies in children, illustrating the diagnostic challenges and complexity of their management. Case 1: A 3-year-old girl presented with a white spot in her left eye present since birth. Uncorrected distance visual acuity was 2/10 in the right eye, while she could perceive hand movements at 2 meters with the left eye. Normal examination in the right eye showed leukocoria, microphthalmia, and a white mass at the center of the optic disc on fundus examination in the left eye. Ocular imaging, including ultrasound and optical coherence tomography (OCT), confirmed the diagnosis of persistent hyperplastic primary vitreous (PHPV) in its mixed form in the left eye. Management included prescribing full optical correction and functional rehabilitation, without resorting to surgery. The course was marked by persistent amblyopia leading to a poor prognosis. Case 2: A 7-year-old girl consulted for vision disturbance in her right eye. Visual acuity was finger counting at 2 meters in the right eye and 10/10 in the left eye. Anterior segment examination revealed no abnormalities in both eyes. However, fundus examination highlighted a large funnel-shaped excavation associated with central glial proliferation, wheel spoke vessels, and neuroretinal ring atrophy in the right eye. Optical coherence tomography (OCT) of the right eye confirmed the diagnosis of isolated unilateral Morning Glory syndrome. Management included full optical correction and orthoptic rehabilitation. The course was marked by the absence of ocular complication and maintenance of visual stability in the right eye. The prognosis seemed favorable. Conclusion: Congenital optic disc anomalies in children exhibit great clinical variability and require an individualized diagnostic and therapeutic approach.展开更多

Method: It was a retrospective study, including all patients with congenital optic disc abnormalities diagnosed at a late age between January 2020 and October 2022 at the eye center of Abass Ndao Hospital. Complete ophthalmological examination was performed with eye imaging according to the cases. Results: 09 patients (10 eyes) were diagnosed with congenital optic disc abnormalities. The mean age was 29 years, with a sex ratio of 0.8. Three patients had consulted for unilateral decreased visual acuity since childhood, two for sudden vision loss and in four cases the diagnosis was fortuitous. Visual acuity was ranged from 1/200 to 20/20. Fundus examination showed myelinated retinal nerve fibers in four eyes, optic disc pit in three eyes including two complicated by maculopathy, two cases of morning glory syndrome and a case of pseudoduplication of the optic disc. Optical coherence tomography, ocular ultrasound B and OCT-Angiography were performed according to the cases. Conclusion: Congenital optic disc abnormalities are often diagnosed late. They are potentially amblyogenic and complications are not rare, worsening the visual prognosis. Their screening should be systematic by ophthalmological examination in newborns.展开更多

Among those cases, 6 were examined with CT, 4 with FFA and 8 with A/B-scan ultrasonography. Results showed that the characteristics of CT, A/B-scan ultrasonography and FFA in MGS included: (1) The attachment spot of optic nerve became thin and vitreous body protruded to the posterior wall of eyeball with a spherical shape on CT image; (2) in the early period of FFA, hypofluorescence appeared on the optic, the abnormal arteriae and veins around the optic papilla were displayed clearly and in the late period, optic disc was stained with fluorescein; (3) on B-scan ultrasonogram, the vitreous cavity extended to the posterior pole and optic papilla, and projected to the basal part of muscle cones and thus the posterior part of vitreous cavity looked like an upside-down bottleneck. Sometimes the echogenic band of retinal detachment could also be seen. On A-scan ultrasonogram, both vitreous cavity and bottleneck showed no ultrasonic echoes and presented a base line without any evident wave crest. It is concluded that CT, A /B-scan ultrasonography and FFA could show the imageological features of MGS from different aspects, which helps clinicians to differentiate it from other diseases such as optic disc coloboma. CT and A /B-scan ultrasonography, in particular, are considered to be reliable imageological methods for the accurate diagnosis of MGS and are superior to the traditional techniques.展开更多

Methods: Eight children with morning glory syndrome (mean age 8.0±2.8 years; range 5~13 years) were included; all patients had unilateral eye disease and were initially misdiagnosed as having bilateral squint or amblyopia, with best corrected visual acuity <6/60. Five patients could not cooperate with the fundus examination and one patient had lens opacities.B-ultrasound confirmed that all eight patients had retinal detachment and optic disc dysplasia.All patients underwent standard 3-port pars plana vitrectomy surgery . (20G for three cases and 23G for five cases).At surgery,all patients were confirmed to have morning glory syndrome,macular hole, and proliferative retinal detachment;.two cases had a funnel shaped bulge. All the retinal detachments involved the macular area, and macular hole was detected in the abnormal expansion excavation of the optic disk. The epiretinal membrane and subretinal membrane were completely removed during surgery. Combined photocoagulation in the abnormal expansion excavation of the optic disk, and silicone oil tamponade were also performed. Results:All eyes achieved anatomical resolution of retinal detachment.After follow-ups ranging from eight months to four years,the visual function for all patients was improved by postoperative refractive correction associated with vision training. Best corrected visual acuity was 6/600 to 6/30 at the final follow-up, no retinal detachment recurred, and no silicone oil fluid entered the subretinal space. The silicone oil was successfully removed postoperatively after a mean of 1.5 years. Conclusion:Vitrectomy with peripapillary photocoagulation and silicone oil tamponade is effective in treating the proliferative retinal detachment associated with macular hole in children with morning glory syndrome.

Pigs were allotted to pens and randomly assigned to three dietary treatments: A) completed feed fed <em>ad libitum</em>;B) complete feed fed at 75% of intake of treatment A, and C) treatment B with <em>ad libitum</em> availability of morning glory. The design was a completely randomized design (CRD) with five pens (replications) of each treatment with four pigs per pen. Average daily feed intake (dry matter basis) was higher (P < 0.001) for pigs fed treatment A (1420 g/d) compared to treatment B (1048 g/d) as expected, with treatment C intermediate (1178 g/d;1048 g/d complete feed + 130 g/d morning glory). Average daily weight gain of pigs fed <em>ad libitum</em> was greater (P < 0.001) than pigs restricted fed with pigs which provide morning glory intermediate (871, 674 and 714 g, respectively). Feed efficiency improved (P < 0.024) for pigs fed the restricted feed level compared to pigs fed complete feed <em>ad libitum</em> or pigs restricted fed but provided morning glory (1.63, 1.56 and 1.65, respectively). For economics, feeding complete feed <em>ad libitum</em> improved (P < 0.001) income over feed cost compared to restricted feeding or providing morning glory (USD 41.48, 33.42, and 33.89/pig, respectively). In conclusion, feeding growing pigs a complete diet <em>ad libitum </em>resulted in the greatest growth rate and profitability. Offering morning glory <em>(Ipomoea. aquatica</em>) to pigs fed a restricted level of complete feed did improve final body weight, but the extra cost of feeding morning glory offset this advantage resulting in similar profitability on an income over feed cost basis.展开更多
