Objective: To compare the pre-operative central corneal thickness (CCT) in paediatric cataract patients with reference to normal control group.
Study Design: A case control study.
Place And Duration Of Study: Paediatric Ophthalmology Clinic of Al-Shifa Trust Eye Hospital (ASTEH), Rawalpindi, from November 2009 to May 2010.
Methodology: The study included 116 subjects with equal number of cases and controls. Demographic profile of all the subjects was noted followed by history and detailed ophthalmic examination. CCT was measured using an ultrasonic pachymeter (model Pac Scan 300). The mean of three measurements from the central cornea were recorded in microns. RESULTS were analyzed using SPSS version 17.0.
Results: Mean CCT values of the cases was 566.83 ± 37.646 microns while the control group had a mean CCT of 535.81 ± 24.466 microns. Difference between the CCT values of the two groups was highly significant (p < 0.001).
Conclusion: Eyes with congenital cataracts have greater CCT values as compared to normal paediatric population. This factor must be kept in mind while interpreting intra-ocular pressure in such patients.

The Captopril Challenge Test Predicts Cardiac Structure and Dysfunction in Primary Aldosteronism.
J Clin Endocrinol Metab

Division of Cardiology, Department of Internal Medicine, National Taiwan University Hospital and National Taiwan University College of Medicine, Taipei, Taiwan.
Context: The captopril challenge test (CCT) is a commonly used confirmation test that identifies the magnitude of renin- and angiotensin II-independent aldosterone production, and thus the presence and severity of primary aldosteronism (PA).
Objective: This study investigated the association between the post-CCT plasma aldosterone concentration (PAC) and cardiovascular remodeling and diastolic dysfunction.
Methods: A total of 540 PA patients with complete CCT and echocardiographic data were retrospectively analyzed.

Background: To evaluate the ocular biometry agreement and prediction of postoperative refractive outcomes obtained using two swept-source optical coherence tomography (SS-OCT) biometers: Anterion (Heidelberg Engineering, Heidelberg, Germany) and Argos (Alcon, Fort Worth, TX, USA).
Methods: Ambispective analysis was conducted on 105 eyes at the Samsung Medical Center, Seoul, Republic of Korea, between June 2021 and March 2022. Biometric values were assessed using both devices before cataract surgery.
Predicting corneal decompensation in Fuchs endothelial corneal dystrophy with Scheimpflug tomography and clinical parameters.

Department of Ophthalmology, Université Paris Cité, Cochin Hospital, Assistance Publique-Hôpitaux de Paris, Paris, France.
Purpose: This study aims to evaluate the efficacy of various tomographic indices, both established and novel, in predicting endothelial decompensation leading to either spontaneous corneal transplantation or transplantation following cataract surgery in patients with Fuchs endothelial corneal dystrophy (FECD).
Methods: In this cross-sectional, retrospective study, we reviewed the files of 93 eyes from 54 FECD patients undergoing regular follow-up. We recorded clinical metrics such as morning visual disturbance (MVD) and corrected distance visual acuity.
