In this retrospective study, the clinical record of all the patients of binocular dysfunction was obtain from Electronic medical record (EMR). We reviewed the record of 527 symptomatic patients with binocular vision dysfunction related problems who were referred between July 2022 to June 2023, to binocular vision therapy clinic. Out of which 393 patients (74.57%) who had accommodative dysfunction were included in the study. Patients with any ocular surgery, manifest strabismus, amblyopia, anisometropia (more than 2.00 dioptres), ocular pathology, neurological disorders, were not included in the review. Prepresbyopic patient also excluded from this study. All clinical assessments were done by one of the two experienced optometrists. Of the 527 symptomatic patients examined, 74% (393 subjects) showed binocular dysfunction. Among the 393 binocular dysfunction patients, most of them diagnose with convergence insufficiency (18.82%), convergence insufficiency with accommodative insufficiency (26.97%), convergence insufficiency with accommodative infacility (23.40%), convergence insufficiency with accommodative excess (19.24%), poor PFV (4.58%), and convergence excess (6.36%).: In conclusion, we have evaluated the binocular vision dysfunctions of a non-presbyobic population. Out of 527 symptomatic patients examined, 74% (393 patients) showed had binocular dysfunctions. Incident CI was more than CE. This study will provide the prevalence data of binocular vision dysfunction. The study will also provide insight into the differences in binocular vision parameters. A diagnosis of binocular dysfunction depends not only on a few clinical findings of some accommodative and binocular investigations but on a whole battery of tests, in order to produce diagnosis of the type of dysfunction of the patient. For this reason optometrists should systematically complement their routine examination with a whole battery of accommodative and binocular tests that would help to avoid the non-detection of these anomalies in daily optometric practice.","PeriodicalId":13485,"journal":{"name":"Indian Journal of Clinical and Experimental Ophthalmology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-07-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141645071","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study was a prospective interventional study in which 35 eyes with corneal perforation (25, 71.4%) and descemetocele (10, 28.5%) of different sizes (2-5.5mm) were surgically treated with tenon's patch grafting (TPG) by a single surgeon at a tertiary centre. Preoperative, operative, and post-operative data were recorded. The eyes were evaluated over a minimum postoperative period of 12 months. The outcome of TPG was assessed based on the achievement and maintenance of the anatomical integrity of the eye. Statistical analysis was conducted using SPSS. The mean size of the corneal lesions for corneal perforation was (3.1±1.04 mm) and for descemetocele was (2.45±0.42 mm). The most common underlying ocular pathology was infectious keratitis in 23(65.7%) patients. The most common systemic comorbidity was diabetes mellitus in 10 (28.5%) patients. At 12 months postoperative follow-up, the integrity of the globe was maintained in 69% eyes. In the entire post-op follow-up eight Keratoplasty procedures, seven cataract surgeries, two repeat TPG procedures and one evisceration were done as additional surgeries.

In the present study, all slides were retrieved and examined to gather information on demographics, laterality, choroid invasion, optic nerve invasion, anterior chamber invasion, tumor discrimination, chemotherapy effects, and tumor regression.In this study, the predominant presenting complaint was leukocoria (90%), with a slight female preponderance (53%), in comparison to males (47%). Unilateral cases accounted for 96%, while bilateral presentations were observed in 4% of cases. The mean age was 38 months, with 43% of eyes exhibiting significant choroid invasion and 27% showing invasion beyond the post-laminar optic nerve or resection margin. 76 patients (56%) underwent primary enucleation and 60 (44%) had secondary enucleation after chemotherapy.
