Life expectancy is gradually increasing due to continuously improving medical and nonmedical interventions. The increasing life expectancy is desirable but brings in issues such as impairment of quality of life, disease perception, cognitive health, and mental health. Thus, questionnaire building and data collection through the questionnaires have become an active area of research. However, questionnaire development can be challenging and suboptimal in the absence of careful planning and user-friendly literature guide. Keeping in mind the intricacies of constructing a questionnaire, researchers need to carefully plan, document, and follow systematic steps to build a reliable and valid questionnaire. Additionally, questionnaire development is technical, jargon-filled, and is not a part of most of the graduate and postgraduate training. Therefore, this article is an attempt to initiate an understanding of the complexities of the questionnaire fundamentals, technical challenges, and sequential flow of steps to build a reliable and valid questionnaire.

Postoperative endophthalmitis can occur after dropless cataract surgery with intravitreal triamcinolone-moxifloxacin.

A 40-year-old man presented with a visual acuity of 20/400 in his right eye due to acute retinal necrosis involving two inferior quadrants. Diagnostic vitreous tap was positive for varicella zoster virus and he received intravitreal injections of ganciclovir (2 mg/0.1 mL) and dexamethasone (400 mcg/0.1 mL). Oral prednisone was added on day 3 and tapered over 3 months. Lesions showed pigmentation around day 5 and healed by day 9. He developed vitreous hemorrhage 5 months after presentation and was treated with 25-gauge pars plana vitrectomy combined with panretinal photocoagulation. Final follow-up at 7 months showed a visual acuity of 20/30, mild optic atrophy, narrow arteries, healed retinal lesions, and good panretinal photocoagulation. Intravitreal injections of dexamethasone and ganciclovir may have a role as an adjunctive therapy in the management of patients with acute retinal necrosis, particularly those caused by varicella zoster virus.
