Acute Angle-Closure Glaucoma: The Second Eye: An Analysis of 200 Cases

New comparative clinical and biometric findings between acute primary angle-closure and glaucomatous eyes with narrow angle

“…In agreement with other studies (6,8,26) , we found that echobiometric characteristics of eyes with angle closure were well correlated with their fellow eyes, which are known to have a high incidence of APAC if left untreated (Table 3). One author documented that without treatment, 58 of 113 patients developed an acute attack in the contralateral eye, one third of these occurring in the first year (27) . Another author reported that 43 of 72 second eyes not treated with LPI went on to develop some form of angleclosure glaucoma (28) .…”

“…It is known that the APAC fellow eyes should be treated with LPI in order to avoid an acute crisis of angle-closure (27)(28) , nevertheless, this treatment is not free of complications and side effects. Several provocative tests have been employed to try to identify patients at risk of developing acute angleclosure glaucoma, but most of them are either not very sensitive (29)(30) or time-consuming, and thus not suitable as screening procedures in general practice.…”

UK national survey of prophylactic YAG iridotomy

“…3 A previous series has demonstrated the characteristics of eyes that develop angle-closure; namely shallow anterior chambers, narrow angles, small corneal diameter, small corneal radius of curvature, short axial length, thick lens, and relative anterior displacement of the lens. 4 There is variation in the estimated prevalence of narrow or 'occludable' angles across the globe, quoted as 2.2-5.0% in Caucasian subjects over 55 years of age, rising markedly to 47.8% in similarly aged Vietnamese subjects. [5][6][7] The annual incidence of acute angle-closure glaucoma (AACG) is estimated at 3.8 per 100 000 in unselected European populations.…”

“…Alguns estudos documentaram a ocorrência de GAP no olho contralateral algum tempo após a eclosão da crise no olho inicialmente afetado (23)(24)(25) . Em trabalho realizado em 1962, constatou-se que, de 113 pacientes com GAP, 58 (51,3%) apresentaram crise no olho contralateral, sendo que, em um terço desses pacientes, a nova crise ocorreu um ano após a primeira (23) .…”

Em 1977, relatou-se que 43 (59,7%) de 72 pacientes não tratados com iridotomia a laser profilática desenvolveram GAP (24) .…”
