Wildlife Ophthalmology
Wildlife Ophthalmology DR. HEATHER REID TORONTO WILDLIFE CENTRE TORONTO, ON CANADA Why understand eyes? Wildlife need to have excellent vision to survive in the wild Eye related problems are common in wildlife admitted to rehabilitation centers What we will cover Anatomy of the eye Differences between birds and mammals The eye exam Recognizing common problems Prognosis Treatment options When to see the vet Anatomy Around the Eye: Muscles & nerves Skin Eye lids Nictitating eyelid Conjunctiva & sclera Tear glands & ducts Ossicles (birds) Anatomy Front of the Eye: Cornea Iris Pupil Ciliary body Anterior Chamber Aqueous humor Anatomy Back of the Eye: Lens Retina Optic nerve Choroid Pecten (birds) Posterior Chamber Vitreous humor Fundus of the Eye Mammal Eye Bird Eye The Avian Eye - Differences Small eye size in most birds and small pupil size makes it hard to examine Can control the size of their pupil Lower eyelid more developed The nictitating membrane spreads the tears allowing birds to blink less Moves horizontally across eye The Avian Eye - Differences Eyes are not as protected by skull Less muscles around eye so less eye movement Boney ossicles support the eye Three main eye shapes; flat, globose & tubular The Avian Eye - Differences Four different color receptors compared to the three in mammals means better color detail Can see in the ultraviolet range Higher flicker rate – can detect lights that flicker at more than 100 flashes per second (humans detect at 50) The Avian Eye - Differences In some species the eye -

Corresponding Author: Dr.Pallavi.M.P ABSTRACT Purpose: To describe various types of ocular trauma due to different modes of injuryoccured on the same day Design: Prospective interventional study (case series) Materials & Methods: A series of cases of ocular trauma in different age group on the same day. Results: Five patients of ocular trauma were studied & managed. All five patients were males. Out of 5 cases, 3 cases had open globe injury and 2 cases had closed globe injury. Three out of five patients required surgical intervention while 2 patients were managed with medical therapy. Conclusion: This study describes the types and characteristics of ocular trauma presenting in eye department. The frequency of ocular trauma is common in males. Eye injuries resulting from ocular trauma pose a frequent threat to vision the world over. While afocussed history and prompt ocular examination are essential to immediate management, patient educationregarding safety precautions and risk reduction help to prevent future recurrences.

Smartphone-Based Dilated Fundus Photography and Near Visual Acuity Testing As Inexpensive Screening Tools to Detect Referral Warranted Diabetic Eye Disease
Smartphone-Based Dilated Fundus Photography and Near Visual Acuity Testing as Inexpensive Screening Tools to Detect Referral Warranted Diabetic Eye Disease BRIAN C. TOY, MD,*† DAVID J. MYUNG, MD, PHD,*† LINGMIN HE, MD,*† CAROLYN K. PAN, MD,*† ROBERT T. CHANG, MD,* ALISON POLKINHORNE, MA,‡ DOUGLAS MERRELL, BS,‡ DOUG FOSTER, MBA,‡ MARK S. BLUMENKRANZ, MD* Purpose: To compare clinical assessment of diabetic eye disease by standard dilated examination with data gathered using a smartphone-based store-and-forward teleoph- thalmology platform. Methods: 100 eyes of 50 adult patients with diabetes from a health care safety-net ophthalmology clinic. All patients underwent comprehensive ophthalmic examination. Concurrently, a smartphone was used to estimate near visual acuity and capture anterior and dilated posterior segment photographs, which underwent masked, standardized review. Quantitative comparison of clinic and smartphone-based data using descriptive, kappa, Bland-Altman, and receiver operating characteristic analyses was performed. Results: Smartphone visual acuity was successfully measured in all eyes. Anterior and posterior segment photography was of sufficient quality to grade in 96 and 98 eyes, respectively. There was good correlation between clinical Snellen and smartphone visual acuity measurements (rho = 0.91). Smartphone-acquired fundus photographs demon- strated 91% sensitivity and 99% specificity to detect moderate nonproliferative and worse diabetic retinopathy, with good agreement between clinic and photograph grades (kappa = 0.91 ± 0.1, P , 0.001; AUROC = 0.97, 95% confidence interval, 0.93–1). Conclusion: The authors report a smartphone-based telemedicine system that demon- strated sensitivity and specificity to detect referral-warranted diabetic eye disease as a proof-of-concept. Additional studies are warranted to evaluate this approach to expanding screening for diabetic retinopathy. -
Effects of Nd:YAG Laser Capsulotomy in Posterior Capsular Opacification
Original Research Article Effects of Nd:YAG laser capsulotomy in posterior capsular opacification Praveen Kumar G S1, Lavanya P2*, Raviprakash D3 1Assistant Professor, 2Associate Professor, 3Professor & HOD, Department of Ophthalmology, Shridevi institute of Medical Sciences and Research Hospital, Sira Road, NH-4 Bypass Road, Tumkur- 572106, INDIA. Email: [email protected] Abstract Background: Posterior capsular opacification (PCO) is the most common long-term complication of cataract surgery in both phacoemulsification and extracapsular cataract extraction (ECCE). The overall incidence of PCO and the incidence of neodymium-doped yttrium–aluminum–garnet (Nd:YAG) laser posterior capsulotomy has decreased from 50% in the 1980s and early 1990s to less than 10% today. Reported complications of Nd:YAG laser posterior capsulotomy include elevated intraocular pressure, iritis, corneal damage, intraocular lens (IOL) damage, cystoids macular edema, disruption of the anterior hyaloid surface, increased risk of retinal detachment, and IOL movement or dislocation. In some patients, a refraction change is noticed after Nd:YAG laser posterior capsulotomy, but proving this remains difficult. Materials and Methods: Nd; YAG LASER capsulotomy was performed in 200 eyes of 200 patients, some with pseudophakia and some with aphakia at Kurnool medical college, Kurnool. They were followed up between October 2008 and September 2010. Results: Elevation of IOP has been well documented after anterior segment laser procedures. The IOP rise after YAG laser posterior capsulotomy is of short duration starting about 1 hr after laser procedure and lasting for 24 hrs. In this study, in 1case IOP came down to normal level after 3 days and in another case after 7 days. -

Endoscopic Vitreoretinal Surgery: Principles, Applications and New Directions Radwan S
Ajlan et al. Int J Retin Vitr (2019) 5:15 International Journal https://doi.org/10.1186/s40942-019-0165-z of Retina and Vitreous REVIEW Open Access Endoscopic vitreoretinal surgery: principles, applications and new directions Radwan S. Ajlan1*, Aarsh A. Desai2 and Martin A. Mainster1 Abstract Purpose: To analyze endoscopic vitreoretinal surgery principles, applications, challenges and potential technological advances. Background: Microendoscopic imaging permits vitreoretinal surgery for tissues that are not visible using operat- ing microscopy ophthalmoscopy. Evolving instrumentation may overcome some limitations of current endoscopic technology. Analysis: Transfer of the fine detail in endoscopic vitreoretinal images to extraocular video cameras is constrained currently by the caliber limitations of intraocular probes in ophthalmic surgery. Gradient index and Hopkins rod lenses provide high resolution ophthalmoscopy but restrict surgical manipulation. Fiberoptic coherent image guides offer surgical maneuverability but reduce imaging resolution. Coaxial endoscopic illumination can highlight delicate vitreo- retinal structures difficult to image in chandelier or endoilluminator diffuse, side-scattered lighting. Microendoscopy’s ultra-high magnification video monitor images can reveal microscopic tissue details blurred partly by ocular media aberrations in contemporary surgical microscope ophthalmoscopy, thereby providing a lower resolution, invasive alternative to confocal fundus imaging. Endoscopic surgery is particularly useful when ocular -
