To study Visual Evoked Potential in patients with Optic Nerve diseases. Study design and settings: Cross – Sectional study. 72 patients were included in our study, aged 12 years and above, diagnosed as optic nerve diseases like optic neuritis, Nonarteritc ischemic optic neuropathy (NAION), hereditary, nutritional and compressive optic neuropathy etc. Flash and Pattern VEPs were used. VEP amplitude and latency were noted. Out of total 144 eyes, 107 eyes were affected. Ethambutol induced Toxic optic neuropathy was the most common etiology, followed by secondary optic neuropathy, idiopathic, traumatic optic neuropathy, optic neuritis, NAION, compressive and post CRAO (Central Retinal Artery Occlusion) optic neuropathy. Mean latency of all affected eyes was 132±22.5 msec. mean amplitude of the all affected eyes was 6.36±2.1 microvolt. Latency was moderately delayed (110-140 msec) in 45.8%, while severely delayed (>140 msec) in 40.3% of total eyes. Amplitude was reduced in 36.5% of total eyes. Prolonged latency with normal amplitude was found in most of the eyes with optic neuritis while latency was also prolonged in fellow eyes of optic neuritis. In case of NAION prolonged latency and reduced amplitude was found in all eyes. Flash or pattern VEP can be used as an important tool for diagnosis of optic neuropathies or revealing of recurrence of disease and for follow up. VEP can also be used to detect subclinical damage in the fellow eyes of optic neuritis and also useful in differentiating the optic neuritis from ischemic optic neuropathy.

Pterygium is a very common ocular surface disorder. Tear film dysfunctions have been reported in subjects with pterygium. We aim to study the correlation between pterygium and dry eye disease in patients with unilateral pterygium. A case–control study of patients with unilateral pterygium was undertaken after ethical clearance from the institutional ethics committee. Eighty-seven patients with unilateral pterygium were included in the study. Tear film break-up time (TBUT), Rose Bengal staining (RBS), and Schirmer’s test 1 were performed in both eyes of the patients. Test results were compared with contralateral normal eye of the same patient. Data were analyzed using t-test and Chi-square test. P <0.05 was considered statistically significant. The tear film function parameters, namely Schirmer 1, TBUT, and RBS in the study group, were statistically different as compared to the control group. The mean of TBUT was 8.19 ± 1.87 s in pterygium eyes and 11.83 ± 1.69 s in contralateral normal eyes. The mean of Schirmer’s 1 was 10.65 ± 3.69 mm in pterygium eyes and 16.37 ± 4.82 mm in contralateral eyes with no pterygium. There was a statistically significant difference in the values of tear film function between eyes with pterygium and contralateral normal eyes.

(1) To assess the knowledge, attitude, and practice about conjunctivitis among patients. (2) To educate society regarding preventive and therapeutic measures. A cross-sectional study, in which 500 patients were selected as participants, knowledge, attitude, and practice were assessed regarding conjunctivitis using prevalidate questionnaire, which contains 20 questions. Descriptive statistics were used to elaborate patients’ demographic characteristics. Categorical variable was percentage while the continuous variable was conveyed as mean ± standard deviation. A significance P < 0.05 was used for comparison. All analyses were performed using the Statistical Package for the Social Science Version 20. Out of 500 distributed questionnaires, 328 were male, 172 were female, majority having age range between 25-60 years. It was seen that 370 participants (74%) have adequate knowledge regarding conjunctivitis. Patients have sufficient knowledge and awareness about conjunctivitis, yet effort should be made to bring change about conjunctivitis. Proper eye health facilities and teaching should be involved in institute health services, and early presentation to eye care centers for its treatment should be encouraged.

To study the demographic profile of keratoconus (KC) patients visiting a tertiary eye care hospital in Western India. This cross-sectional, observational study included newly diagnosed KC patients visiting our hospital between January 2018 and October 2022. Patient’s demographic details (self-reported age at first presentation, age at diagnosis, and sex) and mean maximum curvature (K Max) were collected. The patients were divided into age band of 5-year groups. A subanalysis of gender and severity was performed among groups. Spearman’s correlation coefficient was used to evaluate the relationship between KC severity and age. A total of 536 patients with clinical KC were included. A self-reported age at first presentation was 19.4 ± 6.2 years. The mean age of diagnosis was 20.5 ± 6.0 years (range: 4–43 years). There were 61.6% (330) of males and 38.4% (206) of females (P < 0.01). The mean K Max value was 59.2 ± 13.3 diopter (D). The mean K Max was not significantly different between the sexes, with the exception of the age range of 24–28 years, where females had more severe KC than males (P = 0.02). Among the included patients, 38.6% (207) of patients were pediatrics (≤18 years), while 61.4% (329) were adults (>18 years). The mean K Max in pediatric KC (62.3 ± 15.1 D) was significantly higher than adult KC (57.3 ± 11.5), P < 0.01. Severity of KC did not correlate with the age of the patients (r = −0.20, P = 0.04). KC presented at a younger age with moderate-to-severe stage of the disease, indicating the need for early KC detection in our population.

An ocular injury in a kid is very common, especially in <5 years of age, which ranges from eye adnexa to globe injury. In breastfeeding kids, there are chances of eyelid avulsion with involvement of the canaliculus. In our case series, we report two cases of eyelid laceration and one case of corneal tear due to the use of a safety pin as a blouse hook. Our first case of a 2.5-year-old kid presented with multiple laceration of the eyelid and was managed by primary repair due to the unavailability of mini-monoka stent. The second child was managed well by the mini-monoka stent and had given excellent anatomical as well as functional outcome on 6 months of follow-up. Our third case was corneal tear which was managed well with good visual outcome without cataract formation on 6 months of follow-up.

Parkinson’s disease (PD) is a common degenerative disorder characterized by decreased dopamine levels from damage to the substantia nigra causing classic motor deficits. Several ocular deficits have been recognized in association with PD such as oculomotor disturbances and diplopia, glaucoma and visual field loss, dry eye disease, color and contrast impairment, visual hallucinations, and visuospatial and visuoperceptual impairments. These disorders remain underreported, underrecognized, and poorly understood. Patients with PD are largely dependent on visual cues for compensating the motor deficits. Hence, early recognition and timely management of the above ocular disorders can lead to greater patient safety, independence, and a better quality of life.

Vitreous prolapse is a postcataract surgery complication that can further cause corneal decompensation, glaucoma, macular edema, and retinal detachment. We present a rare case report of delayed vitreous prolapse in a 55-year-old man 20 years after cataract surgery with posterior capsular rupture causing diminution of vision and central corneal decompensation. To our surprise, the intraocular pressure was 18.6 mmHg (within the normal limits). The patient underwent pars plana vitrectomy for the same and had excellent postoperative visual recovery.

The purpose of this study was to describe five case series of patients who presented with isolated homonymous hemianopia (HH) heralding the ministroke. This was a retrospective observational case series. This was a retrospective case series of five patients who presented to the outpatient department with isolated HH and was followed up for 6 months. 30-2 Humphrey's perimetric analysis and neuroimaging was done. Patients also underwent 2D ECHO and 24 h holter monitoring. These patients who presented with isolated HH had best corrected visual acuity of 6/6, N6 with Snellen's chart. Pupils and color vision were normal. On neuroimaging, one patient had infarction only in the occipital lobe. Two had infarction in the cerebellar hemispheres along with the occipital lobe and one patient had infarction in the deep white matter of temporal lobe, corona radiata, and the last patient also had chronic infarct in the frontal lobe. But all these patients presented with isolated HH. 2D ECHO and 24 h holter monitoring were within normal limits and had no neurological deficits. They were put on oral antiplatelets, statins and nutritional supplements, followed up by neurologists for 6 months and showed no neurological deficits on follow up. On finger confrontation test, hemianopia was still persistent. Isolated visual symptoms may be an early presenting characteristic of stroke. As there is a finite window of time during which therapy for stroke is effective, prompt identification of such atypical symptoms is crucial.
本研究的目的是描述五个病例系列的患者，他们表现出孤立的同名偏盲（HH），预示着小中风。这是一个回顾性观察病例系列。这是一个由五名患者组成的回顾性病例系列，他们在门诊就诊时患有孤立性HH，并接受了6个月的随访。进行30-2 Humphrey的视野分析和神经影像学检查。患者还接受了2D ECHO和24小时动态心电图监测。这些出现孤立性HH的患者的最佳矫正视力为6/6，Snellen图表显示为N6。瞳孔和色觉正常。在神经影像学检查中，一名患者仅在枕叶出现梗死。两名患者在小脑半球和枕叶发生梗死，一名患者在颞叶深部白质、放射冠发生梗死，最后一名患者也在额叶发生慢性梗死。但所有这些患者均表现为孤立性HH。2D ECHO和24 h holter监测在正常范围内，没有神经功能缺陷。他们服用了口服抗血小板药物、他汀类药物和营养补充剂，由神经学家随访6个月，随访时没有表现出神经系统缺陷。在手指对抗测试中，偏盲仍然存在。孤立的视觉症状可能是中风的早期表现特征。由于中风治疗有效的时间窗口有限，因此及时识别此类非典型症状至关重要。
