3 IntroductionSevere ocular surface inflammation can lead to different diseases and cause severe corneal involvement;Corneal ulcers in these diseases are chronic and frequently resistant to usual treatments,
4 Patients and methods5 cases of ocular surface inflammation with severe chronic corneal ulcers .All have already experienced different conventional treatments,The corneal ulcers were chronic and rebels to different treatments (lubricants, vitamine A, steroids, ciclosporine, amniotic membrane graft for one case)
5 TreatmentAll patients were treated with Cacicol a new matrix therapy , wich is a regenerating agent,Cacicol was prescibed at a dose regimen of one drop a day every other day for 4 weeksFollow up visits with ophtalmological examination, VAS scale evaluation and biomicroscopic records collected at D0, D3, D7, D15 and D30,
6 PatientsCase 1 : 40 years old man with severe ocular impairment in graft versus host disease (GVHD) in both eyesCase 2 : 51 years old woman with severe dry eye in Sjogren syndrome disease, in left eye (monophtalm patient)Case 3 : 71 years old man with neurotrophic ulcer in left eye (monophtam patient)Case 4: 12 years old child with chronic ulcer in aniridia , in both eyesCase 5: 65 years old woman with chronic ulcer and descemetocel in stevens johnson syndrome, in left eye;
7 Results 7 eyes of 5 patients were treated At D0 VAS pain scale average was 87 on a scale from 0 to 100At D30 mean VAS scale decreased to 30Perfect tolerance of the treatment without any side effect;Perfect corneal healing was observed in all cases at D30 (time to complete healing very variable , from 10 days to 3 weeks),
9 Discussion CACICOL® is a regenerating agent (RGTA) Biodegradable nano-polymer miming glycosaminoglycan,Substitutes with spoiled heparin sulphates in the matrix organisation to interact with structural proteins and growth factors,Matrix architecture is restored by the treatment, helping cell generation and healing.
10 RGTA Molecular Structure ReGeneraTing Agents (RGTA®) are structural analogues of GAGs (glucosaminoglycans)Heparan SulfateRGTAOTR4120
11 ConclusionCACICOL® is a matrix therapy showing great benefits in management of chronic corneal ulcersIndications may substitutes to human amniotic grafts, or autologus serum,Simplifies the treatment,Increase the efficiency,Lower the cost of the management of chronic epithelial defects,More clinical studies are required to proof its efficacy.
