Condition childhood glaucoma
Treatment latanoprost, dorzolamide
Phase phase 2
Sponsor Azienda Ospedaliera Spedali Civili di Brescia
Start date July 2009
End date January 2017
Trial size 69 participants
Trial identifier NCT01527682, 2008-004763-19



The study will assess the ocular hypotensive effect of latanoprost and dorzolamide in a selected sample of patients affected by primary Pediatric Glaucoma (PG), refractory to surgical procedures. Safety will be assessed, too.In the first version of the protocol 96 eyes were forecasted to complete the enrolment. The protocol was then amended and now to complete the study 68 eyes should be included.

Study Design

Endpoint classification safety/efficacy study
Intervention model single group assignment
Masking open label
Primary purpose treatment
According to IOP assessment, the eye will receive Latanoprost, Dorzolamide or both.
latanoprost, dorzolamide - Latanoprost, a prostaglandin analogue
Latanoprost 0.005% ophthalmic solution given once a day at nighttime (9.00 PM) Dorzolamide 2% ophthalmic solution given three times a day as a monotherapy, two times a day if in combination with latanoprost

Primary Outcomes

Eligibility Criteria

Male or female participants up to 12 years old.

Inclusion Criteria: - Children of either sexes, aged 0-12 years - Diagnosis of mono- or bilateral primary congenital glaucoma - IOP greater than or equal to 22 mmHg and lower than 27 mmHg - Only one previous ocular hypotensive surgical procedure for treatment of glaucoma among the following: goniotomy, trabeculotomy, trabeculotomy with adjunct of mitomycin C) (only for medical treatment at least one month before) - Parent informed consent to data processing (at registration) - Parent informed consent before any study procedure Exclusion Criteria: - Secondary glaucoma (Sturge-Weber syndrome, type I neurofibromatosis, retinoblastoma, steroid-induced glaucoma, etc.) - Presence of concomitant abnormalities of the anterior segment of the eye (cataract, iridocorneal dysgenesia, congenital uveal ectropion uvea, etc.) - Previous treatment with the study drugs - Presence of concomitant systemic diseases (asthma, hypertension, cardiac disease, renal failure, etc.) that needs treatment with drugs, that could influence IOP (steroids, beta-blockers, ACE-inhibitors diuretics, etc.) - Abnormalities of the cornea that could influence IOP readings (marked cornea edema)
