Abstract:

Background: Secondary Glaucoma, due to disease or drugs is common in uveitis.
Purpose: To evaluate prevalence of secondary glaucoma (SG) in uveitis with different treatment regimen.
Methods: Randomised prospective hospital based study of uveitis from 2007-2012. Baseline IOP, Field and optic nerve head
photographs were recorded. Three groups were randomised: (1) topical steroid, (2) Systemic steroid+gr-1 and (3) Topical
synthetic steroids, cycloplegic and periorbital triamcinolone injection. IOP more than 22 mm/4mm increase from baseline is
marker.
Results: 1254 uveitis cases, prevalence rate 63/100000 and 82 SG, 70% in anterior uveitis. During treatment, SG was maximum
(80%) in first group and least (5%) with synthetic steroid combined with periorbital triamcinolone. Multi variate analysis
shows synthetic steroid and periorbital triamcinolone has least association with SG.
Conclusion: SG is an underappreciated visual threat in uveitis which can be modulated effectively with newer steroids.

Abstract:

Trabeculectomy and glaucoma drainage device implantation are traditional surgeries and most commonly performed for glaucoma treatment, however, they carry the high rate of many complications and can lead to failure.
Minimally Invasive Glaucoma Surgery (MIGS) is a term which was coined in 2009 by Iqbal Ike Ahmed, MD, and describes a new group of implants, devices or surgical techniques that are less invasive and have lower risks than those of previously established procedures. All MIGS procedures share a number of common characteristics (ab interno microincision, minimal trauma, efficacy, high safety profile, and rapid recovery)1 and have four main mechanisms of IOP reduction as follows:2
1. Increasing trabecular outflow by bypassing juxtacanalicular trabecular meshwork
2. Increasing uveoscleral outflow via suprachoroidal pathways
3. Reducing aqueous production from ciliary body
4. Creating subconjunctival drainage pathway
These new alternative options are mainly indicated for patients with mild to moderate open angle glaucoma and
modest targeted IOP reductions. MIGS are frequently combined with cataract surgery and currently be the most common indication for surgery. Avoiding conjunctival dissection can preserve the tissue and suits for the future invasive surgeries.
MIGS can help minimize the number of medications, reduce the high cost of glaucoma treatment, and increase quality of life. Some MIGS had already been approved by US FDA eg. Trabectome, iStent, Kahook Dual Blade, Cypass, and XEN. And some are still under investigations eg. InnFocus, Hydrus, iStent inject, and iStent supra.3-7

Abstract:

Purpose: To study the role of ultrasound biomicroscopy (UBM) in assessment of the bleb function after trabeculectomy with Mitomycin C (MMC). Study design: Cross sectional study. Methods: Participants were recruited from the followup cases had undergone to trabeculectomy with MMC (0.2 mg/ml for 3 minutes) seen at Tanta University Eye Hospital in the period from Aug 2015 to Aug 2016. Full history taking and ophthalmological examination were performed. Intraocular pressure (IOP) was measured using Goldmann applanation tonometry and history of prescribed postoperative antiglaucoma
medications was recorded. Accordingly, cases were divided into: (20 eyes) of complete success, (9 eyes) of qualified success and (4 eyes) of functional failure. the filtering blebs were scanned by UBM, (VuMAXTM, Sonomed Escalon, USA), with 50 MHz transducer. Results: This study included 33 eyes of 25 patients (9 males and 16 females). The patients' age ranged from
25 to 71 years with mean 53.2 years ± 14.2 SD, the mean recorded IOP was 14.4 mm/hg ± 4.6 SD. UBM examination was performed 2 to 36 months after trabeculectomy with mean 13.6 months ± 9.7 SD. There was a significant correlation between certain UBM findings (the intra bleb reflectivity, draining sub scleral tract, bleb height, and presence of intra-bleb fluid cysts)
and different grades of clinical functional success (P < 0.01). Conclusion: UBM is a useful objective tool in the assessment of the post trabeculectomy filtering bleb as the study showed a significant correlation between certain UBM parameters and the different grades of clinical success.

Syed Mohammad Didarul Alam is an Optometrist at Institute of Community Ophthalmology, University of Chittagong, Bangladesh. Recently He Compeleted his Bachelor of Optometry Degree.His Research interest on Paeditric Optometry, Neuro Visual Science, Neuro-Optometry, Sports Vision, Community Eye Health, Low Vision, Contact lenses and Orthoptics.

Abstract:

The purpose of this study was to find out the ocular status, health seeking behaviors and barriers to uptake eye care services among children of slum community in Chittagong, Bangladesh. The study was conducted in several urban slums in Chittagong city, which is home of slum children. A total of 410 children were clinically examined. Their accompanying guardians were also interviewed for collecting health seeking behaviors and identifying the barriers, if any, to uptake eye care services. Three focus group discussions were held with guardians. Nearly 47.3% of the sampled children were male and 52.7% female. About 40% of children had different ocular complaints, where we found 36.6% having some ocular abnormalities. Most of them (73%) had never seen an eye care specialist. About 89.6% of the respondents have normal visual acuity 6/6. The common ocular problems encountered were Refractive Error (26.7%), Allergic Conjunctivitis (21.3%), Blepharitis (16.0%), Squint (7.3%), Convergence Insufficiency (4.0%), Meibomian Gland Dysfunction (8.7%), Dacrocystitis (3.3%), Congenital Cataract (2.7%), Conjunctivitis (4.0%), Xerophthalmia (1.3%), microphthalmos (1.3%), Ocular FB (1.3%). Infrequently Entropin, Corneal Opacities, Retobulbar Neuritis, Retinal Detachment, Episcleritis, Scleritis, Chalazion, Stye were also present among children. About 4.9% children have night vision problem. About 16.8% of the children complained to have some abnormalities. It may be mentioned that any complaint does not mean that the children have abnormalities because they have not been assessed clinically. Many slum dwellers strongly believe about traditional treatment but most of the guardians (70%) know where to go for the treatment. However, the guardians of slum children cannot afford medical treatment due to their low financial condition.

ophthalmology with further speciality training in Squint and Glaucoma services. Currently she is further pursuing training in anterior segment.

Abstract:

A prospective study was carried out to evaluate changes in Intraocular pressure (IOP) after phacoemulsification in eyes with occludable angle and compare with open angle in eyes without any prior diagnosed glaucoma. 60 subjects were divided into two groups of 30 eyes each into occludable angle (group-I) and open angle (group-II) groups after evaluation by gonioscopy. Patients who required immediate intervention for high IOP or treatment for glaucoma were excluded so that the sole effect of phacoemulsification on eyes could be evaluated. After obtaining institutional ethical clearance and informed
consent, cataract extraction by phacoemulsification was performed in both the groups. Follow-up was carried out on post op days 1, 7, 30 and 90 to evaluate visual acuity, IOP and central corneal thickness (CCT). The two groups showed significant reduction in IOP (p<0.05) with mean reduction of 1.9 mmHg (8.3%) in Group-I (occludable angle) and 1.4 mmHg (6.3%) in Group-II. Our study strengthens the fact that phacoemulsification can be used as an entity to decrease IOP along with cataract removal in occludable angle eyes showing high pre-op IOP without prior diagnosed glaucoma.

Biography:

Shubhank Khare has his expertise in evaluation and passion in improving the health and wellbeing of patients and their caregivers. His study emphasizes that
community-based support for the visually impaired individuals as well as for the caregivers should be a priority.

Abstract:

Caregivers who assist persons with visual impairment often neglect their needs, resulting in burden and depression. Rehabilitation efforts, directed to the disabled, seldom target the caregiver. This cross-sectional study was carried out in the outpatient department of a tertiary-level teaching hospital to assess burden and depression in persons caring for blind individuals. Institutional Ethical Board approval was obtained and written informed consent too was obtained from the participants involved in this study. Persons with best-corrected vision <20/200 in the better eye and their primary caregivers, were recruited. We recorded demography, other illness/disability, household income, relationship with disabled person, and caregiver burden (Caregiver Burden Scale) and depression (Centre for Epidemiologic Studies Depression Scale). Statistical analysis was carried out using SPSS version-20 (Released 2011. Armonk, NY: IBM Corp.); range, average and standard deviation were determined for age, burden and depression. The association between burden and depression was determined using Pearson's correlation, the relationship between degree of disability and caregiver burden and depression was determined using unpaired t-test, using multiple linear regression, factors were found to be statistically significant; significance was taken at P<0.05. 27 (53.0%) men and 24 (47.0%) women had visual impairment. Most caregivers (n=40; 81.6%) were first-degree relatives or a spouse; 32 (65%) had schooling <5 years and 29 (59%) were unemployed. Depression ranged from 21 to 52 (average 43.2±5.71), it correlated with degree of disability (P=0.012), household income (r=0.320; P=0.025) and burden (r=0.616; P<0.001). Burden ranged from 30 to 73 (average 54.5±6.73) and correlated with degree of disability (P=0.006). On multiple linear regression, burden predicted depression (r=0.557; P<0.001). Caregivers merit community support, financial benefit, interventions to diagnose and treat depression and training in coping. Centers that provide disability certification could offer counseling.

Abstract:

This prospective randomized case-control study is done to evaluate the efficacy of autologous Anterior Lens Capsule (ALC) in phacotrabeculectomy. After obtaining institutional ethical clearance and informed consent, 88 eyes posted for phacotrabeculectomy were divided into ALC (Group-I) and Non-ALC Group (Group-II). Combined phacoemulsification, with posterior chamber intraocular lens implantation and trabeculectomy was performed in both groups. Anterior lens capsule transplantation was done in the first group (Group-I) beneath the sclera flap. Follow up of 3 months was carried out
where in the morphology of bleb, intraocular pressure (IOP), requirement for additional medications and complications were compared between the two groups. Statistical difference favoring ALC group was seen in IOP reduction (p<0.05) at each follow up, qualified success rate and failure rate 3 month follow up (p=0.006) but no difference in bleb morphology was seen. The
authors believe that ALC implantation is beneficial in maintain filtration in a combined surgery with minimal complications.

Abstract:

Statement of the problem: There are various descriptive studies on different techniques of supracapsular phacoemulsification that claim to have lesser risk of complications like posterior capsular rent and nucleus drop and increased risk of corneal endothelial damage compared to conventional in the bag techniques of phacoemulsification. But to the best of our knowledge, there is only one comparative study between supracapsular phacoemulsification and in the bag phacoemulsification. Also, the studies do not describe the efficacy, safety and functionality of supracapsular phacoemulsification in different grades of nucleus sclerosis.

Purpose: To compare the safety and efficacy of Maloney’s Supracapsular technique with Stop and Chop phacoemulsification
in different nucleus sclerosis grades.

Methodology: A prospective randomized interventional study comprising of 153 patients undergoing surgery by two
techniques, evaluated for intraoperative phacoemulsification parameters, complications and endothelial cell loss and change in morphology (coefficient of variation and hexagonality).

Findings: Operative time, ultrasound time (41.28 ±19.20s and 88.41 ± 43.24s), cumulative dissipated energy (10.18±5.03 and 24.77±13.09), effective phaco-time, fluid volume, aspiration time and postoperative corneal thickness (on day-1: 575.72 ± 57.7 μ and 605.88 ± 57.49 μ) were significantly higher in stop and chop group. Endothelial cell loss (on day-1: 7.21% and 7.49%) was significant but comparable in two groups. No difference in complication rate. No significant correlation with nucleus hardness was seen with the corneal parameters where as an increase in each phacoemulsification parameter was seen with increase in nuclear hardness, with grade 3 using maximum time and energy.

Conclusion & Significance: Supracapsular technique uses less phaco-energy and time and both techniques are comparable with respect to final visual outcome and complications, including corneal edema and endothelial cell loss.

Abstract:

Introduction & Aim: Children after traumatic corneal lacerations, suffering from irregular corneal astigmatism, spectacle best-corrected (SVA) of less than 20/20 and unilateral amblyopia in children with BCVA less than 20/40. The purpose of this study was an objective evaluation of the clinical value of Rigid Gas Permeable Contact Lenses (RGPCLs) by investigating the cornea profile, optical defects and the simulated vision functions by using the Sirius topographer.

Methodology & Theoretical Orientation: A comparative study of visual acuity correction and improvement of visual disorders as corneal aberrations as (HOAs, LOAs, PSF and with and without RGPCLs fitting in 15 children with history corneal scars after trauma or irregular corneal incision after cataract extraction operation. We compared the UCVA, Spectacle (VA) and the BCVA post while fitting RGPCLs. We used the Sirius topographer (CSO) for evaluation of aberrometric corneal analysis preand while fitting RGPCLs.
Findings: Our study included fifteen children were fitting RGPCLs for 6 months under specific study wear regimen. Their age range was from 5-9 years with mean 7.2±1.1 SD. There was a significant improvement in the best corrected visual acuity and keratometric astigmatism while wearing RGPLCs (P=0.001). There was also a significant improvement in corneal aberrations
as; HOAs (P=0.008), LOAs, RMS & PSF (P=0.001).

Conclusion & Significance: The optical performance of RGP contact lens has been demonstrated to be an effective tool of visual rehabilitation in children with traumatic corneal lacerations. The corneal topography was an objective tool for detecting the optical disorders other than subjective tests of visual acuity assessment.

Abstract:

There is a great responsibility of an ophthalmologist while examining a patient in search or follow up of Glaucoma. Evaluation of glaucoma may start with the intraocular pressure measurement but the actual thing is start with the optic nerve head. So, the responsibility of an ophthalmologist is not merely to define the cup disc ratio but to carefully note and describe all the necessary relative information while evaluating the optic nerve head (ONH). From the first day in ophthalmology we are hearing about cup disc ratio and most of the time we are least bother about disc diameter. Only describing Cup Disc Ratio may be misleading because a large ONH have thinner neural rim width and large cup size despite a stable number of axons. Assessment of disc size is one of the initial step. So, we as an ophthalmologist have to prepare our mind to see the details of ONH. I will describe the importance of examination of ONH in detail with emphasis on disc size, cupping, neuroretinal rim and signs of progression.

Abstract:

Statement of the Problem: Patients with epiretinal membrane usually have coexisting cataract at presentation. Phacovitrectomy has become a common procedure in epiretinal membrane cases and offers quicker visual rehabilitation and reduce costs for additional surgery. In this study, we evaluate the accuracy of intraocular lens power estimation and the factors associated with outcome including preoperative central macular thickness in phacovitrectomy for epiretinal membrane.

Methodology & Theoretical Orientation: We performed a retrospective case review of 42 consecutive patients that underwent phacovitrectomy for epiretinal membrane. Axial lengths were measured using ultrasound (A-scan) and optical biometry (IOL Master). Achieved and predicted refractions were compared to calculate the mean postoperative refractive prediction error
(ME). Several preoperative and postoperative factors including preoperative central macular thickness measured by OCT related to the postoperative refraction were analyzed.

Findings: The goal diopters measured by A-scan and IOL Master were 0.05 ± 0.21 diopters (D) and -0.07±0.34 D, respectively with no statistical significant difference between the diopters (p=0.168). The actual postoperative manifest refraction was -0.43±0.43 D, which was statistically significant tendency to a myopic shift from the goal diopters (p<0.001, 0.003). ME of 23 eyes using A-scan and IOL Master were −0.48±0.46 D and -0.36±0.49 D, respectively. There was no statistically significant difference in the refractive outcomes between the refractive errors (p=0.407). Preoperative mean central macular thickness measured by ocular coherence tomography was significantly decreased after surgery from 462.50±48.30 μm to 372.39±47.70
μm (p<0.001). The decrease in central macular thickness showed the correlation with the magnitude of postoperative myopic shift (r=0.479, p=0.044; r=0.485, p=0.041).

Conclusion & Significance: Combined phacovitrectomy in epiretinal membrane showed small biometric errors within the tolerable range in most cases. The decrease in central macular thickness had a significant correlation with the magnitude of postoperative myopic shift.
