This document describes different types of keratitis, including ulcerative keratitis, non-ulcerative keratitis, and infective keratitis caused by bacteria, fungi, viruses, and protozoa. It discusses the classification, etiology, signs, diagnosis, and management of various forms of corneal inflammation and infection. Key pathogens mentioned include Staphylococcus aureus, Pseudomonas, herpes simplex virus, acanthamoeba, and fungi like Aspergillus and Fusarium.
Rigid Gas Permeable Lenses Complications and Management
Contact lenses are used to correct refractive error, improve visual acuity, and enhance appearance for cosmetic reasons.
RGP lenses can provide sharper vision correction than soft lenses for a few different reasons. First of all, they won't dry out and fluctuate in shape the way soft lenses can. Gas permeable lenses are custom-made to have a smooth surface and hold their shape on the eye. The wear of RGP contact lens can damage normal physiological function of tears and aggravate dry eyes. These slides describe the Complication of RGP lenses and required Management
Congenital glaucomas are a group of disorders where abnormal high intraocular pressure results from developmental abnormalities of the anterior chamber angle that obstruct aqueous humor drainage. They can be primary, caused by trabecular meshwork maldevelopment, or secondary, associated with other ocular or systemic anomalies. Surgical treatment via goniotomy or trabeculotomy aims to create a drainage pathway and lower pressure. Medications may be used before or after surgery to control pressure. Early diagnosis and treatment leads to the best visual prognosis.
This document provides information on the management of cataracts, including both non-surgical and surgical approaches. Non-surgical management focuses on controlling underlying causes, delaying progression, and improving vision. Surgical management involves extracting the opaque lens using various techniques like intracapsular cataract extraction (ICCE), extracapsular cataract extraction (ECCE), or phacoemulsification. Pre-operative evaluation is important to assess retinal function and rule out infections. Intraocular lenses are then implanted to restore vision.
Vision 2020 is a global initiative to eliminate preventable blindness by 2020. It targets diseases like cataract, refractive errors, childhood blindness, trachoma, and onchocerciasis globally. In India, it also focuses on glaucoma, corneal opacity, and diabetic retinopathy. The program implements a 4-tier system of primary vision centers, secondary service centers, tertiary training centers, and centers of excellence. Onchocerciasis is not included for India since it is not prevalent, and epidemic conjunctivitis is excluded globally and nationally. Cataract is the major cause of blindness in India. School screening programs help identify and refer children who cannot read certain lines to community health centers
This document provides an overview of procedures for examining the eyes in an outpatient department (OPD). It describes taking a patient history, assessing vision, performing a torch light examination, slit lamp evaluation, and fundus evaluation. Key areas examined include visual acuity, refraction, visual fields, eyelids and adnexa, pupil response, ocular motility, the anterior chamber, iris, lens, and intraocular pressure. Examination findings are used to identify common pathologies that may cause sudden or gradual vision loss or pain. A thorough eye exam evaluates both the anterior and posterior segments to screen for ocular diseases.
Trachoma is a chronic conjunctivitis caused by Chlamydia trachomatis that often leads to blindness. It spreads through direct contact with eye and nose discharges of infected individuals or through flies. Repeated infections cause scarring of the eyelid that turns the eyelashes inward, damaging the cornea. Over 150 million people worldwide require treatment for active trachoma infections. The WHO's SAFE strategy aims to eliminate trachoma through surgery, antibiotics, facial cleanliness, and environmental improvements.

The cornea can recover from minor injuries on its own. If it is scratched, healthy cells slide over quickly and patch the injury before it causes infection or affects vision. But if a scratch causes a deep injury to the cornea, it will take longer to heal.

This document discusses hordeolum or styes, which are red, painful lumps near the eyelid caused by bacterial infections or blocked oil glands. It describes the types of styes, etiological factors, signs and symptoms, diagnostic evaluation, pathophysiology, and management. Styes are usually external, located at the base of an eyelash follicle or internal, found in the oil glands inside or under the eyelid. Management involves application of warm compresses, cleansing, and topical antibiotic ointments and eye drops. Complications can include infection of the eyelids or surrounding tissues if not properly treated.
This document discusses bacterial keratitis and corneal ulcers. It defines bacterial keratitis as any corneal inflammation caused by bacteria, and a corneal ulcer as bacterial keratitis accompanied by a loss of epithelium. It then lists common bacterial causes and describes characteristics of infections caused by different bacteria. The document provides guidance on diagnosing, treating, and managing bacterial keratitis and corneal ulcers.
Uveitis refers to inflammation of the uvea, which is the middle layer of the eye that includes the iris, ciliary body, and choroid. Uveitis can be classified based on the location of inflammation as anterior, intermediate, posterior, or panuveitis. Common causes include infection, autoimmune disorders, and malignancy. Symptoms include eye redness, pain, blurred vision, and sensitivity to light. Diagnosis involves examination with a slit lamp and tests to identify underlying causes. Treatment focuses on managing inflammation with corticosteroids and treating any underlying condition. Complications can include cataracts, glaucoma, cystoid macular edema, hypotony, and retinal detachment if uve
This document discusses the verification process for contact lenses. It has two main stages - laboratory and clinical. In the laboratory, lenses are checked to ensure their parameters match what was ordered. Clinically, lenses should be verified upon receipt to ensure the correct lens was dispensed. Parameters like radius of curvature, diameters, thickness and power must be measured for both rigid and soft contact lenses using various techniques and instruments. On-eye verification is also important to assess fit and comfort. The goal of verification is to ensure patients receive high quality lenses that meet specifications and provide good vision.
Acute catarrhal or acute muco purulent conjunctivitisPraful SonnePatil
1) The document discusses acute catarrhal or acute muco-purulent conjunctivitis, listing causes, symptoms, signs, diagnostic criteria, complications, and treatment options.
2) Common causative organisms include staphylococcus, pneumococcus, and adenovirus. Symptoms include redness, discharge, photophobia, and sticking eyelids.
3) Treatment involves washing the conjunctival sac with saline, using mild astringent or antibiotic drops, and avoiding steroids. Homeopathic medicines like Belladonna and Euphrasia are also effective options.
1. Microbial keratitis is caused by bacterial or fungal infection of the cornea and can lead to corneal scarring and perforation if not treated promptly.
2. Common bacterial causes include Pseudomonas aeruginosa, Staphylococcus aureus, and Streptococci. Risk factors include trauma, contact lens wear, and topical steroid use.
3. Fungal keratitis is less common but more difficult to treat. Filamentous fungi like Aspergillus and Fusarium and yeasts like Candida are common causes. Risk factors include ocular surface disease, contact lens wear, and immunosuppression.
This document discusses techniques for measuring corneal thickness, known as pachymetry. It begins by introducing pachymetry and its importance in assessing corneal health and thickness. It then describes 12 techniques for measuring corneal thickness, including the gold standard of ultrasonic pachymetry. The document provides details on the principles, advantages, and disadvantages of each technique. It concludes by discussing the clinical utility of pachymetry in procedures like LASIK and for conditions like glaucoma and keratoconus.
This presentation describes the background of the cornea and the corneal diseases in general, also it describes in detailed manner how to manage the corneal ulcer with its different causes
Assessment and management of strabismus conquest 10 feb 2011Hossein Mirzaie
This document discusses the assessment and management of strabismus, or eye misalignment. It covers the development of visual acuity from infancy through childhood, techniques for assessing vision at different ages, and the development of binocular single vision. It also briefly classifies different types of strabismus, describes tests for assessing strabismus, and outlines the typical management approach, including correction of refractive errors, occlusion treatment, exercises, and possibly surgery. Risk factors for strabismus development include prematurity, developmental delays, refractive errors, and family history.
This document provides an overview of conjunctivitis, including:
- The anatomy and histology of the conjunctiva.
- The signs and symptoms of conjunctivitis.
- Bacterial conjunctivitis (BC), its etiology, clinical presentations, laboratory findings, differential diagnosis, complications, treatment, and typical course.
- Details are given on diagnosing and treating different types of BC, from hyperacute to chronic forms.
This document discusses bacterial keratitis, including common pathogens, risk factors, symptoms, signs, investigations, management, and visual rehabilitation. It notes that Pseudomonas aeruginosa and Staphylococcus aureus are common causes. Risk factors include contact lens wear and ocular surface disease. Treatment involves topical antibiotics, with fluoroquinolones or combination therapy used. Steroids may be added after initial antibiotic treatment but are avoided if thinning/perforation occur. Systemic antibiotics are used if systemic involvement is possible. Surgical intervention like patching or keratoplasty may be needed for perforations or dense scarring.
Viral conjunctivitis is caused by various viruses that infect the conjunctiva. The most common types are adenoviral conjunctivitis, caused mainly by adenovirus types 8 and 19, and herpes simplex conjunctivitis caused by HSV-1. Adenoviral conjunctivitis presents with redness, watering, follicles and can cause punctate keratitis if the cornea is involved. Treatment focuses on supportive care and antibiotics to prevent secondary infections. Acute hemorrhagic conjunctivitis is caused by enterovirus 70 and presents with redness, watering, hemorrhages and follicles. Ophthalmia neonatorum can be caused by gon
Fungal keratitis is an infection of the cornea caused by fungi, typically seen after injury involving vegetable matter or contact lens use. Common causative organisms include Aspergillus, Fusarium, and Candida albicans. Symptoms include defective vision, photophobia, watering, and conjunctival congestion. Signs include a dry-looking corneal ulcer with an irregular border and satellite lesions. Diagnosis involves KOH wet mount, culture, and USG to check for endophthalmitis. Treatment consists of antifungal medications like natamycin or amphotericin B for filamentous fungi and nystatin for yeast. Surgery such as corneal grafting may also be required
An intraocular lens (IOL) is an artificial lens implanted in the eye during cataract surgery or refractive lens exchange to replace the natural crystalline lens and correct vision. IOLs have evolved over generations from rigid PMMA lenses to modern foldable designs made of silicone, acrylic, or hydrogel materials. IOLs are either placed in the posterior chamber behind the iris or in the anterior chamber in front of the iris. Newer multifocal and accommodating IOL designs aim to provide both distance and near vision. Precise biometry is required to calculate the optimal IOL power to achieve the desired postoperative refraction. Potential complications include dislocation, opacification, deposits, and inflammation.
The document summarizes common pathologies of the eyelids and adnexa. It discusses that eyelid lesions are similar to skin lesions elsewhere on the body and includes cysts, inflammations/infections, metabolic changes and degenerations, and tumourous conditions. Specific conditions covered include inclusion cysts, retention cysts, dermoid cysts, blepharitis, hordeolum, chalazion, and molluscum contagiosum. The document provides details on the types, causes, and characteristics of these common eyelid conditions.
This document provides an overview of retinoscopy, including:
- A brief history and the development of different types of retinoscopes.
- The optical principles behind how retinoscopy works to assess refractive error.
- Different techniques for performing retinoscopy, including static, dynamic, and near retinoscopy.
- Factors that can impact the results or make retinoscopy more difficult in some patients.
- Uses of retinoscopy beyond assessing refractive error, such as detecting other ocular issues.

Keratokonus– stadiengerechte Therapie und Astigmatismus – bogenförmige Keratotomien“ – vorgetragen auf dem Innovations-Symposium Augenchirurgie 2014 in Düsseldorf.
Comparison of the two treatments for Keratoconus shows: iCXL is only a treatment for grade I (and II)
Increase irradiation period: from 30 min to 40 min
- more time for oxygen diffusion
- compensates for epithelial UV-absorbance
With regard to safety and predictability ReLEx SMILE is slightly better than Femtosecond LASIK. No overall superiority of any method. More long-term data needed
The Conclusion of the analysis was:
No consistent statistically significant dependency between postoperative regression and the considered preoperative parameters could be detected. Stability of postoperative results after ReLEx SMILE is equally good for all included cases.
Intelliaxis-L capsular marks provided excellent alignment of toric IOLs, with a surgical misalignment of only 0.74° ± 0.58° in 77 eyes. After 3 months, misalignment increased slightly to 3.00° ± 3.99°, around half the errors reported in literature. Capsular marks were more reproducible, sharper, and closer to the IOL plane than corneal marks, improving precision of toric IOL alignment. Capsular marks were still visible in only 21% of eyes after 3 months.
Dr. Breyer presents data and subjective patient reports: Patients report a more „crisp“ vision in the Fine Vision TriumF eye when compared to classical trifocal Fine Vision IOL in the other eye.
This presentation compares the 5-year-outcomes after small incision lenticule extraction and femtosecond lasik. According to the patient questionnaire, there are less dry eyes, less pain sensation and better patient comfort in ReLEx SMILE group and
ReLEx SMILE is the treatment of choice.

• Abwarten
• Hohe Spontanheilungstendenz
• 80 – 90% Abheilung innerhalb der ersten 4 Monate
• aber Rezidivrate von 30 % bis 50%
• Mehrfachrezidive bei ca. 10% der Patienten
• Bei Rezidiven reduzierte Visusprognose
• Ersterkrankung beobachten bis zu 4 Monate
