Background: Dry eye disorder is a disease mainly due to the tear insufficiency which results in eye discomfort and disturbances in vision. Dry eye also affects the ocular dimensions, especially corneal thickness. Central corneal thickness (CCT) assessment plays an important role in refractive surgeries and in the pre-operative assessment of other ocular surgeries. Aims and Objectives: This study aims to assess the effect of dry eye disease (DED) on CCT with age- and gender-matched controls. Materials and Methods: One hundred and four subjects (52 cases and 52 controls) who attended SRM Medical College and Hospital ophthalmology outpatient department were included in the study. DED was diagnosed with DEQS questionnaire, slit-lamp examination, TFBUT, and Schirmer’s test. Pachymetry was used for measuring the CCT of all subjects. Student “t”-test was used to determine the significance of difference between two means. P

Background: Rheumatoid arthritis is an autoimmune disease. It is a chronic disease that causes symmetrical deforming type of polyarthritis. Rheumatoid arthritis most commonly involves the anterior segment of the eye. It causes keratoconjunctivitis sicca, episcleritis, scleritis, sclerosing keratitis, stromal keratitis, paracentral keratolysis, and peripheral ulcerative keratitis. Aims and Objectives: The purpose of this study was to evaluate central corneal thickness (CCT) and corneal curvature in patients with rheumatoid arthritis. We also evaluated the association between CCT, corneal curvature, and rheumatoid arthritis severity. Materials and Methods: A total of 49 rheumatoid arthritis patients and 49 control subjects were enrolled in this study. The study was conducted in the ophthalmology department of SRM medical college, Chennai. A detailed ophthalmological examination was performed on each subject. Dry eye evaluation was done using Shirmers test, tear breakup time, and corneal fluorescein staining. The CCT and corneal curvature were measured by ultrasonic pachymetry and auto keratorefractometer, respectively. For statistical analysis, we used chi-square test, Fisher exact test, student t-test, and ANOVA test. Results: Mean CCT in all rheumatoid arthritis patient group eyes was 532.78±14.03 micrometers. Mean CCT in rheumatoid arthritis with dry eye was 522.3±11.10 micrometer, in rheumatoid arthritis without dry eye was 536.90±11.60 micrometer and control patients’ group was 564.80±20 micrometer respectively. The difference of CCT was found to be statistically significant (P

Pigmented paravenous chorioretinal atrophy (PPCRA) is an uncommon retinal disorder of unknown etiology that is neither well understood nor classified. We report an atypical case of PPCRA, associated with Coat′s like response (CLR) in a 64-year-old man of Asian origin. Both the eyes were involved, though asymmetrically.
