Abstract:

Statement of the Problem: Primary congenital glaucoma (PCG) is one of the causes of childhood blindness. Surgery is the only treatment. The initial procedures of choice  are angle surgeries (goniotomy, trabeculotomy) and, when they fail glaucoma drainage device (GDD) implantation is an options, with  Ahmed glaucoma valve (AGV) being one of the most widely used. All studies on AGV in PCG include a small number of patients because of the rarity of the disease, and therefore further studies are needed. The purpose of this study is to report long-term outcomes of AGV  implantation in children with PCG who have failed previous surgeries. Methodology & Theoretical Orientation: The medical records of consecutive children with PCG and a history of previous failed angle surgery who underwent AGV implantation between 2005 and 2015 were retrospectively reviewed. Surgical success was defined as IOP 5 -22 mm Hg (with/without glaucoma medications), without need for additional glaucoma surgery or serious complications.

Abstract:

Although elevated intraocular pressure (IOP) is the main risk factor for glaucoma, other risk factors and in particular vascular risk factors have been implicated in the pathogenesis of glaucoma. Impaired microcirculation in the Optic Nerve Head may contribute to the initiation and progression of glaucomatous neuropathy. It has been proposed that the main pathologic changes in glaucoma are located in the deep vascular areas in Optic Nerve Head region. To find out the co-relation between ONH microvasculature perfusion and ocular pulse amplitude and their effect on Retinal Nerve fiber Layer Thickness in glaucomatous optic neuropathy. Study was conducted with 100 subjects aged 30-50, who were diagnosed with glaucomatous optic neuropathy and grouped as Normal Tension Glaucoma, Primary open angle glaucoma and non-glaucomatous. In every subject Peripapilary Vascular Perfusion (PVP), Ocular pulse amplitude (OPA) and Retinal nerve fiber layer thickness (RNFLT) was measured. In every group, glaucomatous stages and  glaucoma suspects showed significantly lower blood perfusion index compared with normal eyes (P ≤ 0.0015).Blood perfusion showed a direct correlation with Ocular perfusion pressure calculated with OPA (P ≤0.0123). Similar discrimination capability PVP compared with RNFL thickness was found in both disease groups. Impaired blood supply to the Optic Nerve head peripapilary area, may cause to develop RNFL thinning which directly leads to glaucomatous optic neuropathy. Investigations on PVP and OPA will provide a very early diagnosis and a repeatable follow up baseline for the disease

Abstract:

To predict the window period of stroke, Cerebrovascular Accident (CVA) by analyzing ocular risk factors. A retrospective study was performed in all consenting patients with diagnosis of stroke made by the consultant of neurology unit of multispecialty hospital from Dec 2017-May 2018. 24 cases with mean age of 60 years were included. Total 83.3% of the stroke cases showed ocular features of which 33% had diplopia and 6^th nerve palsy. Pre-stroke ocular findings from records shows 16.6% HTN retinopathy for mean period of 18  and 16.5% had Diabetic Retinopathy for 14, retinal vasculopathy seen in 25% including CRAO, CRVO for 1-3 m and BRVO for 3-6. Ocular risk factors can predict imminent stroke. HTN retinopathy and Diabetic Retinopathy are the long-term risk factors (>1 year) whereas BRAO (<6) and CRAO, CRVO (<3) are short term risk factors. Hence early prediction can help in early management thus reducing the occurrence of stroke

Abstract:

Statement of the Problem: Following the Tube Versus Trabeculectomy (TVT) study there has been a growing trend toward using tube-shunts rather than trabeculectomy in eyes with previous cataract extraction and/or failed glaucoma surgery. The TVT study however, examined only the Baerveldt implant and it is unknown whether the study results are applicable to other tube-shunts. The Ahmed Glaucoma Valve (AGV) is one of the most popular tube shunts. In recent years, trabeculectomy has been improved by the use of the Ex-PRESS shunt implanted under a scleral flap. Studies which directly compared AGV implantation versus Ex-PRESS surgery, showed similar outcomes for both operations, in complicated glaucoma cases. The purpose of this study was to compare outcomes of AGV and Ex-PRESS surgeries in pseudophakic patients, a group of patients similar to that in the TVT study.

Methodology & Theoretical Orientation: The records of patients who underwent AGV implantation or Ex-PRESS surgery and had prior clear-corneal phacoemulsification alone or failed trabeculectomy following phacoemulsification were reviewed. Surgical success was defined as IOP between 5 mmHg and 21 mmHg and a 20% IOP reduction from baseline (with/without glaucoma medications) without glaucoma reoperation.

Findings: Ninety two patients (92 eyes) were included (43 AGV, 49 Ex-PRESS). Overall success at 3 years was 92.7% for AGV and 66.1% for Ex-PRESS (P=0.006). Glaucoma reoperation rates was lower for AGV than for Ex-PRESS (4.6% and 30.6%, respectively, p=0.001). Similar rates of surgical success were observed with both implants, for patients with only previous phacoemulsification (87.5% AGV vs. 69.4% Ex-PRESS, P=0.205). AGV however, had a higher success rate in patients with failed trabeculectomy (96% AGV vs. 64.1% Ex-PRESS, P=0.023).

Conclusion & Significance: In patients with prior clear-corneal phacoemulsification, AGV compared to Ex-PRESS shunt has similar success rate for primary surgeries and higher success rate for secondary surgeries.

Abstract:

The aim is to describe the use of Fibrin Tissue Adhesive (FTA) as a tissue sealant and hemostatic agent in various ophthalmic surgeries. Ninety-six (96) consecutive surgical procedures consisting of 28 orbital, 52 eyelid, 14 pterygium and 2 strabismus surgeries were performed in 72 patients from February to August 2002; one surgeon performed all surgeries. FTA (Tisseel, Immuno Baxter Healthcare Corporation, Deerfield, IL) was adjunctively used as a tissue graft, implant sealant and hemostatic agent in all cases. Fibrin tissue adhesive was used in 28 orbital, 52 eyelid, 14 pterygium and 2 strabismus procedures. Intraoperative observation of less need for cautery, decreased number of sutures applied, absence of drains in orbital surgeries and a markedly diminished post-operative swelling and hematoma formation were noted. No complications were encountered. Fibrin tissue adhesive is an effective and useful adjunctive hemostatic agent and tissue graft and implant sealant in various ophthalmic surgical procedures

Abstract:

Aim is to investigate whether autologous activated omental cells are as effective as fat derived stem cells in healing process of alkaline burn in limbus of rats. Corneal alkaline burn was created in three groups of rats (each group was composed of six rats). Then each group were treated differently : Group-1 (control group) with topical medication only, Group-2: Subconjunctivally injected by autologous activated omental cell (AAOC) after alkaline burn induction , Group-3: Subconjunctivally injected by non-autologous abdominal Fat Derived Stem Cells (FDSC). Clinical outcome was evaluated after 2 months by corneal reepithelization, corneal opacity and neovascularization. Pathologic study was done to asses corneal integrity and cell proliferation. After three weeks all three groups had relatively same degree of corneal neovascularization and opacity. But at the time of 2-month follow-up, Group-3 rats showed the best clinical results with more clear, healed cornea compared with other groups. All rats on group-1 developed severe central corneal neovascularization and opacity with no healing. Auto evisceration was done in two of them. In group-2, most cases achieved a clear cornea with peripheral neovascularization two of them developed central corneal neovascularization, but in group-3, none of the rats developed central corneal neovascularization and all corneas were relatively clear with no epithelial defects. Activated omental cells are as effective as fat derived stem cells in prevention of corneal neovascularization and wound healing after alkaline burn. Some differences between group-2 and 3 were detected, that should be evaluate in future studies
