Trabeculectomia com mitomicina C em pacientes com glaucoma congênito refratário

Abstract: INTRODUÇÃOA mitomicina C (MMC), antimetabólito alquilante, atua ligando-se ao DNA, acarretando ligações anômalas e quebras em sua estrutura, inibindo a mitose, a síntese protéica e levando à morte celular (1) . Inicialmente, foi utilizada como terapia adjuvante após exérese de pterígio (2) . Chen em 1983 foi quem primeiro relatou o seu emprego em cirurgias antiglaucomatosas (3) . A partir de então, vários estudos evidenciaram que seu uso no per-operató-rio reduz a cicatrização da ferida cirúrgica (4)(5)(6) . A… Show more

“…Young patients are known to be refractory to trabeculectomy without MMC. However, they seem to be more prone to ocular hypotony (26) and other serious retinal complications when MMC is used, particularly hypotonic maculopathy, as was seen in patients 1, 5, 7, 12 and 16. In one paper in which nine patients had undergone primary trabeculectomy with MMC, the authors reported chronic hypotonic maculopathy in five (55.6%) eyes (15) .…”

“…In the present study, this comparison was conducted by the table presented in the reference (1) , with the correlation being performed between the APD (in mm) and the age (in months) in normal eyes and in the patients studied, taking into account the mean value as well as the values found in the confidence interval of 95% (1) and the values in the existing forecast line (1) . In general the treatment of congenital glaucoma is surgical (1,2,(5)(6)(7)9,(11)(12)(13)17,18) , and clinical treatment is used only as a support (1,5,17) . The first choice for clinical treatment is the eyedrops of beta-blockers and carbonic anhydrase inhibitors (5,17) , and the alpha agonist eyedrops are contraindicated (1.17).…”

“…Due to consanguinity, GCP is more frequent in isolated populations, such as in Saudi Arabia (1:2,500) (2,6) , among gypsies in Slovakia (1:1,250) (6) and among people of Andhra Pradesh, India (1:3300) (6) . The treatment for congenital glaucoma is essentially surgical (1,2,(5)(6)(7)(8)(9)(10)(11)(12) . Goniotomy is the chosen procedure whenever the degree of corneal transparency allows to realize it (1,5,6) .…”

“…Cyclophosphamide belongs to the group of chloroethylamines and is a bifunctional alkylating agent with no specificity for any phase of the cell cycle (17) . On the other hand, mitomycin is an alkylating antimetabolite agent which binds to the DNA causing anomalous bonds and breaks in its structure, inhibiting mitosis and protein synthesis, and leading to cell death (18) . The inhibitory action of cyclophosphamide on the in vitro proliferation of fibroblasts suggests that it could be used to prevent the recurrence of pterygium after its removal.…”
