Prevalence of refractive errors, uncorrected refractive error, and presbyopia in adults in India: A systematic review Sethu Sheeladevi, Bharani Seelam, Phanindra B Nukella, Rishi R Borah, Rahul Ali, Lisa Keay Indian Journal of Ophthalmology 2019 67(5):583-592 Purpose: The objective of this review is to estimate the prevalence of refractive errors, uncorrected refractive error (URE), and uncorrected presbyopia in adults aged ≥30 years in India. Methods: The Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines were followed. A detailed literature search was performed to include all studies published from India from the year 1990 using the Cochrane Library, Medline, and Embase. Refractive error was defined by >0.50 D ametropia. URE was defined by presenting visual acuity (PVA) worse than 6/18 improving with pinhole or spectacle correction, and uncorrected presbyopia by near vision

Comparison of the safety and efficacy of topical Tacrolimus (0.03%) versus dexamethasone (0.05%) for subepithelial infiltrates after adenoviral conjunctivitis Rahul Bhargava, Prachi Kumar Indian Journal of Ophthalmology 2019 67(5):594-598 Purpose: To compare the safety and efficacy of tacrolimus 0.03% ointment with dexamethasone 0.05% ointment for subepithelial infiltrates (SEIs) following adenoviral keratoconjunctivitis (AK). Methods: A randomized, double blind trial was done. Eligibility criteria was corrected distance visual acuity of 6/9 Snellen or worse for at least 4 weeks with corneal SEIs following AK. The grading of SEIs was done on a scale of 0 to 3; 0, no infiltrates, 1 mild infiltration, 2 moderate infiltration and 3, severe infiltration. Consecutive patients with SEIs following AK were randomized to receive either topical tacrolimus 0.03% or dexamethasone 0.05% ointment twice daily for 6 months. Treatment was successful if there was reduction of SEIs and improvement in vision. Results: A total of 45 patients each were assigned to the Tacro and Dexa groups, respectively. Baseline characteristics of patients did not differ significantly (P > 0.001). There was a significant change in symptoms, vision and SEIs in both the groups. However, the magnitude was greater in tacro group. Treatment was successful in 37 (92.5%) patients in Tacro and 34 (85%) patients in dexa group. In dexa group, after a period of 1.24 ± 0.24 months, 7 (15.6%) patients developed a significant rise in intraocular pressure (IOP). Three (7.5%) eyes in tacro and 6 (15%) eyes in dexa group had recurrence of SEIs after cessation of therapy. Conclusion: Tacrolimus 0.03% is an effective alternative to dexamethasone 0.05% with low recurrence rate, no significant rise in IOP but may cause burning and foreign body sensation in some patients.

Objective optical assessment of tear-film quality dynamics in patients with meibomian gland dysfunction and aqueous-deficient dry eye optical quality changes in different dry eye subtypes Fen Ye, Feng Jiang, Yan Lu, Chun Yan Xue, Xiao Min Zhu, Yan Wu, Zhen Ping Huang Indian Journal of Ophthalmology 2019 67(5):599-603 Purpose: To evaluate the optical quality and tear-film dynamics in patients with aqueous-deficient or evaporative subtype of dry eye disease (DED). Methods: Twenty-five aqueous-deficient dry eye (ADDE) patients, 25 DED patients with meibomian gland dysfunction (MGD), and 25 healthy subjects were included in this study. Vision-related health-targeted quality of life was evaluated using the Ocular Surface Disease Index (OSDI) questionnaire. Dynamic recording with a double-pass system (Optical Quality Analysis System [OQAS]) was performed in right eyes. Scattered light was measured as the objective scatter index (OSI) at 0.5-second intervals over 20 seconds without blinking. Then, we recorded OSI every 0.5 seconds within a 20-second period with the subjects asked to blink freely. Several parameters were established to evaluate the dynamic alterations of optical quality and the effects of blinks: OSI, OSI standard deviation (SD), ΔOSI, ΔOSI/time, blinking change (BC), and blinking frequency (BF). Additional clinical examination included tear film break-up time (BUT), Schirmer I test (SIT), fluorescein staining grade (FL), meibomian gland quality, meibomian gland expressibility, and meibomian gland drop-out. Results: The OSI, SD, ΔOSI, ΔOSI/time, BC, and BF were significantly higher in DED patients than controls (P < 0.01, respectively). The OSI, SD, ΔOSI, ΔOSI/time, BC, and BF were significantly higher in patients with MGD than patients with ADDE (P < 0.01). In the MGD group, BUT, FL staining score, lid abnormality, meibomian gland expressibility, and meibomian gland drop-out were correlated with Δ OSI and Δ OSI/time. Conclusion: Dry eye patients with MGD had significant alterations of optical quality compared with ADDE patients. The double-pass system has potential to be a useful quantitative method to evaluate the optical quality and tear-film dynamics in patients with dry eye.

Iridocorneal endothelial syndrome: Evaluation of patient demographics and endothelial morphology by in vivo confocal microscopy in an Indian cohort Chintan Malhotra, Natasha G Seth, Surinder S Pandav, Arun K Jain, Sushmita Kaushik, Amit Gupta, Srishti Raj, Deepika Dhingra Indian Journal of Ophthalmology 2019 67(5):604-610 Purpose: To evaluate the patient demographics and morphological characteristics of corneal endothelium by in vivo confocal microscopy (IVCM), in patients with Iridocorneal Endothelial (ICE) Syndrome. Methods: In this retrospective observational series, IVCM acquired endothelial images of patients with ICE syndrome were evaluated. 'ICE cells' morphology was classified as “−” or “+” if they were larger or smaller than contralateral normal endothelium. It was correlated with patient demographics and clinical manifestations. Results: IVCM was performed on 41 eyes of 21 patients, with 13 males (62%) and 8 females (38%). The disease was unilateral in 19 (90.5%) and bilateral but asymmetric in two (9.5%) patients. Total ICE was seen in 91% eyes. Eighty percent patients (12 out of 15) with ICE—cells were males while 83.3% (5 out of 6) patients with ICE + cells were females. Mean age of patients with ICE- cell type and ICE + cell type was 45.8 ± 17.8 years and 40.3 ± 9.2 years respectively (P = 0.02). Both ICE – and ICE + eyes had similar incidence (33.3%) of corneal edema. ICE + eyes had more severe (grades 2/3) glaucoma (n = 5/6 eyes, 83.3%) compared to ICE – eyes (n = 8/15 eyes, 53.3%). Conclusion: A male preponderance, predilection of ICE – and + cell variants for male and female gender respectively, lack of association of the endothelial cell morphology with corneal edema, and apparent association of ICE + phenotype with more severe glaucoma occurring at a relatively younger age, are some novel findings of the present study. In the clinical setting correlation of patient demographics with these IVCM findings may help in better long-term prognostication of eyes with ICE syndrome.

Discharge teaching, readiness for discharge, and post-discharge outcomes in cataract patients treated with day surgery: A cross-sectional study Chujin Qiu, Xianqiong Feng, Jihong Zeng, Hongmei Luo, Zhifeng Lai Indian Journal of Ophthalmology 2019 67(5):612-617 Purpose: To investigate the quality of discharge teaching, readiness for hospital discharge (RHD), and post-discharge outcomes (PDO) of cataract patients in a day ward and to explore the relationships among these three variables. Methods: This cross-sectional study used an opportunistic sample from the ophthalmic day ward in a general hospital in Sichuan province, China. Data were collected using four questionnaires. Results: The total average score on the Quality of Discharge Teaching Scale was 192.95, and the dimension with the lowest score was “guidance obtained practically.” The total average score on the Readiness for Hospital Discharge Scale was 175.51, and the dimension with the lowest score was “knowledge of disease.” The total average score on the Post-Discharge Outcome Questionnaire was 77.08, and the four dimensions with the lowest scores were “compliance behaviors,” “avoiding excessive use of eye,” “avoiding strenuous exercise,” and “regular check-up.” Pearson correlation coefficients indicated low to moderate correlations between discharge teaching quality and PDO (0.245, P < 0.01), RHD and PDO (0.271, P < 0.01), and discharge teaching quality and PDO (0.559, P < 0.01). Conclusion: The quality of discharge teaching among cataract patients who underwent day surgery was relatively high, and patient preparation for discharge and PDO were good. However, medical staff should focus more attention on patients' individualized needs for discharge teaching while emphasizing the importance of compliance behavior.
