The National Eye Institute Visual Function Question naire-25 , Impact of Vision Impairment and Treatment Satisfaction Survey-Intraocular Pressure had the highest number of positive ratings in the content validity assessment .
Conclusion This study provides a descriptive catalogue of vision-specific PRO instruments , to inform the choice of an appropriate measure of patient-reported outcomes in a glaucoma context
Purpose To identify  vision Patient-Reported Outcomes instruments relevant to glaucoma and assess their content validity .
Comparison of Efficacy and Tolerability between Two Gel-Forming Timolol Maleate Ophthalmic Solutions in Patients with Glaucoma or Ocular Hypertension
Purpose : To compare two gel-forming timolol maleate ophthalmic solutions , Timoptol XE ® and Lizmon TG ® , in regard to efficacy and tolerability in patients with glaucoma or ocular hypertension by means of a patient-masked prospect i ve r and omized crossover study . Subjects and Methods : A total of 37 patients with glaucoma or ocular hypertension under treatment with antiglaucoma ophthalmic solutions including 0.5 % twice-daily timolol maleate  participated in this study . Only timolol maleate was withdrawn and either Timoptol XE or Lizmon TG was r and omly allocated . After instillation for 1 month , the other ophthalmic solution was subsequently instilled for another month . Routine ophthalmic examination including slit-lamp examination and intraocular pressure ( IOP ) monitoring was conducted before instillation of gel-forming ophthalmic solutions and just after completing the instillation of each ophthalmic solution . Patient question naire surveys were also performed just after completing the instillation of each ophthalmic solution . Results : Mean IOP , just before the withdrawal of timolol ophthalmic solution , was 16.4 ± 2.9 mm Hg . At the end of Timoptol XE or Lizmon TG instillation , mean IOPs were 16.3 ± 2.5 or 16.3 ± 3.0 mm Hg , respectively . The results of the question naire survey showed no significant difference between Timoptol XE and Lizmon TG in regard to all survey items . Twenty-nine patients ( 78.4 % ) preferred to use gel-forming timolol solutions rather than twice-daily timolol ophthalmic solution . The presence of concurrently used ophthalmic solutions did not effect the incidences of subjective symptoms . The incidences of objective adverse effects were not significantly different between two gel-forming timolol ophthalmic solutions . Conclusion : Both gel-forming timolol ophthalmic solutions could be good choices for glaucoma treatment
