E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
Assess which of the two treatments results in a greater improvement in objective signs of dry eye in a month (improvement of at least 2 degrees of the scale of Oxford). |
Valutare quale tra le due terapie determina un maggiore miglioramento dei segni oggettivi di secchezza oculare a un mese (miglioramento di almeno 2 gradi della scala di Oxford). |
|
E.2.2 | Secondary objectives of the trial |
Assess which of the two treatments results in a greater improvement in subjective signs of dry eye in a month.
Assessing whether there is a difference in response to therapy based on the severity of symptoms at baseline and between the two groups (group artificial tears and autologous serum) that within the same treatment group.
Assessing whether there is a difference in response to therapy according to the different pathological condition that determines the dry eye is between the two groups (the group artificial tears and autologous serum) that within the same group of therapy.
Determine the efficacy and safety of topical treatment with autologous serum in dry eye disease. |
Valutare quale tra le due terapie determina un maggiore miglioramento dei segni soggettivi di secchezza oculare a un mese.
Valutare se esiste una differenza di risposta alla terapia in base alla gravità dei sintomi alla baseline sia tra i due gruppi (il gruppo lacrime artificiali e siero autologo) che all’interno dello stesso gruppo di terapia.
Valutare se esiste una differenza di risposta alla terapia in base alla diversa condizione patologica che determina la secchezza oculare sia tra i due gruppi (il gruppo lacrime artificiali e siero autologo) che all’interno dello stesso gruppo di terapia.
Determinare l’efficacia e la sicurezza del trattamento topico con siero autologo nella malattia dell’occhio secco. |

• by reduction of tear production (Aqueous Deficient Dry Eye ADDE) and comprises:
• dry eye associated with Sjogren's syndrome
• Primary: presence of ADDE in combination with the symptoms of dry mouth, presence of autoantibodies, evidence of reduced salivary secretion and score positive on biopsy of a minor salivary gland.
• Secondary: combines the features of primary SS with features of autoimmune connective tissue disease a clear (RA, systemic lupus erythematosus, polyarteritis nodosa, Wegener's granulomatosis, systemic sclerosis, primary biliary sclerosis)
• dry eye not associated with Sjögren's syndrome:
• for primary and secondary deficiencies of the lacrimal gland |
1- Presenza di alterazione corneale (cheratopatia puntata) e/o congiuntivale almeno di grado I° secondo la classificazione dello Schema Oxford (Allegato A) dopo colorazione con fluoresceina per la cornea e con verde lissamina per la congiuntiva.
2- Tear break-up time fluoresceina < 10 sec (cut-off stabilito per la diagnosi di occhio secco da Lemp e Hamill nel 1973)
3- Presenza di occhio secco causato da:
• da riduzione della produzione lacrimale (Aqueous Deficient Dry Eye ADDE) e comprende:
• occhio secco associato a sindrome di Sjogren
• primaria: presenza di ADDE in combinazione con i sintomi della bocca secca, presenza di autoanticorpi, evidenza di una ridotta secrezione salivare e score positivo alla biopsia di una ghiandola salivare minore.
• Secondaria: combina le caratteristiche della SS primaria con le caratteristiche di una chiara malattia connettivale autoimmune (AR, lupus eritematoso sistemico, poliarterite nodosa, granulomatosi di Wegener, sclerosi sistemica, sclerosi biliare primaria)
• occhio secco non associato a sindrome di Sjogren:
• per insufficienze primarie e secondarie delle ghiandole lacrimali |
