Objective: To investigate the application of the calculated electrophysiological parameters in early diagnosis of carpal tunnel syndrome (CTS). Methods: 44 patients (60 hands) with a diagnosis of CTS and 31 healthy volunteers (44 hands) were enrolled. Acquired indicators include median nerve distal motor latency (DML), complex muscle action potential (CMAP) amplitude, conduction velocity (MCV), median nerve sensory nerve action potential (SNAP) amplitude, and conduction velocity (SCV). Then the terminal latency index (TLI), the residual latency (RL), and the difference in peak sensory latencies between the median and ulnar nerves (ΔPSL) were calculated. Results: The two groups were matched in age and gender distribution. The CTS group showed significant difference in SCV, DML, SNAP, and CMAP compared with the control group. The sensitivity, specificity, cutoff value, Youden index, and area under the curve of each indicator are respectively as follows: TLI (0.733, 0.932, 0.622, 0.629, and 0.877), RL (0.750, 0.977, 1.334, 0.727, and 0.907), ΔPSL (0.950, 0.841, 0.150, 0.791, and 0.942), SCV (0.950, 0.796, 56.5, 0.746, and 0.946), DML (0.867, 0.932, 3.55, 0.799, and 0.930), SNAP (0.683, 0.932, 21.68, 0.615, and 0.844), and CMAP (0.683, 0.773, 8.76, 0.456, and 0.758). Conclusion: The calculated electrophysiological parameters have higher sensitivities and specificities relative to a single electrophysiological parameter, which could greatly improve the accuracy of early diagnosis of CTS.

AIM: To investigate the efficacy, safety and localization of multilayer amniotic membrane transplantation (AMT) for the management of corneal perforation associated with ulceration.METHODS: Six eyes (6 patients) were treated with multilayer AMT for corneal perforation associated with ulceration. The perforation size was 0.5-2mm in diameter. The amniotic membrane (AM) was applied to tamp the perforation, fill the ulcer and cover the surface of ulcer. The follow-up ranged from 5-19 months.RESULTS: The anterior chamber reformed at the first postoperative day in all patients, and kept in normal depth in the follow- up time. The epithelialization of the AM grafts was observed in about 3 weeks after surgery. During the first postoperative month, the corneal thickness at the perforation site gradually increased, and the stromal inflammatory cell invasions surrounding the corneal ulcer were gradually subsided.Two months postoperatively, the ulcer healed with scar with part neovascutarization; the corneal thickness of the ulcer area was stable and recovered almost normal. The vision was not improved in all patients after operation. During-follow up,no severe complications or recurrence of ulceration was noted.CONCLUSION: Multilayer AMT is an effective and safe method for the management of small corneal perforation associated with ulceration, but the ulcer healed with scar.

AIM: To evaluate the efficacy and safety of annular bubble conjunctival excision combining with amniotic membrane transplantation(AMT) for vernal keratoconjunctivitis(VKC) with gelatinous swellings(papillae) at the limbus.METHODS: Twenty eyes(10 patients) with VKC, were characterized by gelatinous swellings(papillae) at limbus and were underwent annular bubble conjunctival excision associated with AMT. The follow up ranged 5-21months.RESULTS: After operation, the symptoms were subsided remarkably: itching,discharge and foreign body sensation were almost disappear; photophobia and tearing were obvious in the first week after surgery, but were gradually alleviated, and almost disappear after one month of postoperative.Yellow-brown or filthy red gelatinous protuberances at limbus were cleaned away by operation and did not recur during the follow up. Corneal superficial punctuate keratitis(11 eyes) and corneal ulcers(3 eyes) were healed during the first week after surgery and did not recur. Conjunctival congestion was gradually lessened after surgery, which could not be noted 1months after surgery in 19 eyes, and the conjunctiva around the limbus, where AMT was performed, was whiter than the normal. But conjunctival congestion in 1 eye lasted for about 5mon accompanying with a little of itch, and this eye was treated with eyedrops with improvement but recurrence. No severe complications had been seen during the follow up.CONCLUSION: Annular bubble conjunctival excision combining with amniotic membrane transplantation is an effective and safe method for the treatment of vernal keratoconjunctivitis with gelatinous swellings (papillae) at limbus. But the candidates must be chosen with discretion.

AIM: To investigate the efficacy and safety of annular conjunctival excision combined with amniotic membrane transplantation for the management of earlier Mooren's ulcer.METHODS: Thirty eyes (24 patients) with earlier Mooren's ulcer were treated with this method, followed-up for 5-30mo. The characteristic of these patients was localized periphery corneal ulcer: the ulcer involved 30-120° corneal limbus with depth of 1/3-1/2 cornealthickness and width of 2-5mm.RESULTS: After surgery, symptoms subsided remarkably and immediately in all patients,and almost disappeared after stitches were removed. Corneal melts were controlled. At postoperative 2-3mo, the corneal thickness of the ulcer area became almost stable, which in some patients recovered normal and in others were still thinner than normal, and the average increase was about 1/3 of the corneal thickness. Corneal transparence and vision were improved. During follow-up, no severe complications or recurrence were noted.CONCLUSION: Conjunctival peritomy combined with amniotic membrane transplantation is an effective and safe method for the treatment of earlier Mooren's ulcer.

Objective To investigate the efficacy,safety and localization of multilayer amniotic membrane transplantation(AMT) for corneal perforation associated with ulceration.Design A retrospective clinical case series.Participants Nine patients(9 eyes)with corneal perforation secondary to ulceration were enrolled into this study.These were little response to medicine,including bacterial keratitis(4 eyes ),fungal keratitis(2 eyes),fungal and bacterial mixed keratitis( 1 eye),virus keratitis( 1 eye),and Mooren's ulcer ( 1 eye).Size of perforation was 0.5～3.0 mm in diameter.Methods The AMT was applied to tamp the perforation,fill the ulcer and cover the surface of ulcer.After surgery,the medicine was continued to be used to treat the original corneal ulcer.The follow-up ranged from 6～20 months.In the suffering eyes,reformation of anterior chamber,healing of ulcer,complications and recurrence of ulceration were observed.Main Outcome Measures Of the postoperative eyes,reformation of anterior chamber,healing of ulcer,complications and recurrence of ulceration.Results The anterior chamber reformed at the first postoperative day in 9 eyes,and kept in normal depth in the follow-up time.At postoperative 2 months,the ulcer healed with sear and a smooth surface.Corneal thickness of the ulcer area recovered almost to normal.During follow up,no recurrence of ulceration or severe complications was noted.Conclusions Multilayer AMT is a safe and effective method for the management of small corneal perforation associated with ulceration,but the ulcer healed with scar.(Ophthalmol CHN,2008,17:101-103)
