ABSTRACT
In the present study, 80 eyes of 40 patients with glaucoma, glaucoma suspect and ocular hypertension and visual acuity of 6/12 or better were studied. In these patients, contrast sensitivity measurements were done using Pelli-Robson contrast sensitivity chart and were related to visual field loss on perimetry using on Humphrey's visual field analyzer model in order to obtain mean deviation. Mean deviation in decibel was converted in log units (1 dB = 0.1 log units). In the present study, contrast sensitivity losses were noticed in only small number of patients as compared to mean deviation shown by these patients on perimetry. Although contrast sensitivity has proven to be an important test for the early detection/screening of the people for glaucoma in some studies, we observed that contrast sensitivity testing by means of Pelli- Robson chart was not as efficacious as automated threshold perimetry for early detection of glaucoma.
ABSTRACT
The current study was done to evaluate the utility and safety of Trypan Blue staining of the anterior capsule for enhancing visualization of capsulorrhexis in mature and hypermature cataracts.This study included 100 eyes of 100 patients with a unilateral mature or hypermature cataract. In all these cases 0.2ml of 0.1% Trypan blue dye was used to stain the anterior capsule in cataract surgery. In all 100 eyes the Continuous Curvilinear Capsulorrhexis (CCC) was completed. Successful cataract surgery with intraocular lens (IOL) implantation was performed in all eyes. Adverse reactions related to the dye such as raised intraocular pressure or anterior chamber inflammation was not observed in the immediate postoperative period or at the end of mean follow-up of 3 months.Trypan blue dye staining of the anterior capsule was found to be an effective and safe technique that helps in completion of Continuous Curvilinear Capsulorrhexis (CCC) in mature and hypermature cataracts.
ABSTRACT
The present study was undertaken to find out the incidence of convergence insufficiency in patients presenting in eye OPD with chief complaints of headache. Only patients with normal visual acuity and fundus picture were included in this study. All the 100 patients included in this study were subjected to detailed orthoptic examination which included tests for near point of convergence by RAF, Maddox rod tests and synaptophore examination. It was found that a substantial number of patients had convergence insufficiency and maximum no. of such patients (49%) were in the age group of 20-40 years. The sudy highlights the importance of ortoptic examination in all patients of strain and headache.
