“…This is of relevance, particularly to Asian Chinese as they are known to have a high prevalence of pre-existing narrow angle. [6][7][8][9] We investigated in this pilot study, whether asymptomatic angle narrowing occurs in Chinese patients taking topiramate using ultrasound biomicroscopy (UBM).…”

Purpose To investigate whether subclinical ciliochoroidal effusion and resulting asymptomatic angle narrowing occurs in patients taking topiramate, by ultrasound biomicroscopy (UBM). Methods Chinese patients aged 18-75 years for whom topiramate was indicated were recruited. Examinations including UBM were performed before and 4 weeks after commencement of topiramate. Results In this pilot of 20 eyes of 20 patients, there were no statistically significant changes in the angle parameters noted on gonioscopy or UBM, including anterior chamber depth, angle-opening distance at 500 lm, trabecular ciliary process distance, trabecular-iris angle, and scleral thickness. Conclusion Short-term use of topiramate does not induce asymptomatic angle narrowing.

“…They found that there was no difference in visual acuity or disease progression between the 2 treatment groups. 66 In an ongoing study at our center, lens removal was found to be effective in majority of the cases with less than three quadrant PAS (unpublished data).…”

“…Two RCT 64,65 were conducted in Hong Kong comparing phacoemulsification with phacotrabeculectomy in medically controlled and medically uncontrolled chronic angle closure glaucoma. They showed lower intraocular pressures with phacotrabeculectomy than with phacoemulsification alone, but the difference was marginal and mostly statistically significant.…”

“…19 In another study on 52 medically uncontrolled PACG eyes with cataract, they noted better IOP control with combined surgery but again with greater post-operative complications. 20 They opined that further study is required to determine whether this marginally better IOP control with combined surgery justifies potential additional risks of complications.…”

“…15 For PACG eyes, the IOP response is much more and ranges from 2-8mmHg with a mean reduction of 6mmHg documented by a recent report released by American Academy of Ophthalmology (AAO). [16][17][18][19][20]10 Comparative studies between POAG and PACG subsets have clearly documented better response in ACG group in terms of IOP control and number of medications required, occurring despite a pre-existing patent laser iridotomy thus negating the aspect of relieving pupil block element as the sole cause.…”
