“…Moreover, its translucency gives the patient’s eye a better cosmetic appearance [ 23 ], which is most relevant in cases where the GDD is placed in the inferior quadrants [ 22 ]. Migration, retraction and twisting are possible complications of the tube [ 24 , 25 ], and they may be difficult to diagnose under an opaque patch graft, such as sclera or pericardium. The translucency of the cornea allows direct visualization of the underlying tube and greater facility in the diagnosis of possible complications [ 4 ].…”

BackgroundTo protect from erosion of the tube in glaucoma drainage device (GDD), the tube is covered by a biologic tissue which is roofed by the conjunctiva. Sclera, pericardium, dura mater and cornea are available as a patch graft. Drawbacks of some of these materials may include high cost and poor appearance. The purpose of this study is to report the long-term outcomes of partial thickness corneal grafts to cover the tube and prevent its exposure, in GDD surgeries.MethodsThis was a retrospective review of all patients who underwent Ahmed glaucoma valve implantation and had a minimum follow-up of 12 months. The tube was covered by a 300-micron partial thickness corneal graft taken either from a previous Descemet stripping endothelial keratoplasty procedure or cut from a whole corneal graft button unsuitable for keratoplasty.ResultsForty-four patients (45 eyes, mean follow-up of 27.6 ± 11.4 months) were enrolled. The partial thickness corneal grafts maintained clarity throughout follow-up with satisfactory cosmetic results. Mild conjunctival retraction occurred in 4 eyes (8.9 %) between 1 and 12 months after the surgery. Corneal graft melting occurred in 3 (6.7 %) eyes. Tube exposure and additional surgery to re-patch or suture the conjunctiva over the tube was needed in 1 (2.2 %) eye. None of the patients had graft infection or immunologic rejection.ConclusionsPartial thickness corneal grafts have favorable long-term outcome as a patch for GDD tubes with low rates of tube exposure and other complications.

“…[14] Corneal allograft has many advantages over other materials. [12,16,20,22,33] The cornea is structurally tight and hard, and thus does not easily melt. Moreover, the translucency of the cornea gives the patient's eye a better cosmetic appearance, especially when the surgical site is at the inferior conjunctiva.…”

Objective:The aim of the present study was to observe the feasibility and effect of cornea slice acquired from femtosecond laser surgery, small incision lenticule extraction (SMILE) as patch graft for the prevention of drainage tube exposure and to compare with the sclera.Methods:The research is a prospective comparative randomized study. Patients who received Ahmed glaucoma valve implantation surgery from August 2015 to January 2017 at the Xiamen Eye Center were randomly divided into 2 groups. Group A (corneal group) included 131 cases (135 eyes), receiving the 3 layers of allogeneic cornea slices as graft. Group B (scleral group) included 124 cases (127 eyes), using the sclera as allograft. The appearance, graft, conjunctiva melting, and tube exposure were the primary observation points.Results:After followed up for 6 to 20 months, a thinner appearance was seen in 3 eyes (2.2%) in the corneal graft group and 7 eyes (5.5%) in the scleral group. Conjunctiva melted and drainage tube exposed in 0 eyes (0%) in the corneal graft group and 2 eyes (1.6%) in the scleral group. One eye needed repair surgery. There was no statistical difference between the 2 groups (P > .05). After surgery, the intraocular pressure was reduced significantly in both groups (P < .05). The white sclera slice could be seen under the conjunctiva, thereby affecting the cosmetic appearance.Conclusion:The cornea slice acquired from SMILE surgery can effectively prevent drainage tube exposure. Moreover, it is easy to acquire, safe, and cheaper, giving the patient a better cosmetic appearance.

[15] Prenatal diagnosis by means of ultrasonography, fetal magnetic resonance imaging and fetoscopy is possible. On obstetric ultra sound scan, amniotic bands can be seen as linear echoes floating in the amniotic fluid and connected to the fetal body such abnormalities are generally diagnosed at the end of the first or the beginning of the second trimester using two-dimensional ultrasonography (2DUS).…”

to determine presentation of constriction band syndrome and its association with other congenital anomalies seen at our institution. Ten patients with constriction band syndrome were included in the study. All were admitted through the outpatient department. The site and extent of each constricting ring and related anomalies were recorded. Surgery was performed. The most common associated anomalies were syndactyly, acrosyndactyly, hypo plastic phalanges, lymph edema and Talipes Equino Varus. Such type of study in our population is conducted for the first time which shows that constriction band syndrome is also not uncommon in our setup and successful surgical repair is also possible. Further research is also required in order to diagnose this in uterus, intra uterine lysis/ surgical intervention and possible causative factors needs elaboration.
